1.  Purpose
1.1  The purpose of this document is to define good practice and to establish a reasonable approach for the performance of an inspection of a commercial property.
2.  Definitions
2.1  Core Definitions
2.1.1  Commercial Property:  A commercial property is defined as the building structures and improvements located on a parcel of commercial real estate.  These may include structures such as buildings with residential units operated for profit, mixed-use buildings, strip malls, motels, factories, storage facilities, restaurants and office buildings.
2.1.2  Inspection:  The inspection is defined as the process of an inspector collecting information through visual observation during a walk-through survey of the subject property, conducting research about the property, and then generating a meaningful report about the condition of the property based on the observations made and research conducted by the inspector.  A commercial inspection requires the inspector to make observations, conduct research, and report findings.
2.1.2.1  Observations:  Observations are defined as those potential items of interest noted by the inspector during the walk-through survey portion of the inspection.
 
2.1.2.2  Research:  Research is defined as the process of gathering information through document review and interviews to augment the observations made during the walk-through portion of the inspection.  This research may include reviewing readily available documents, such as previous inspection reports, building permits, code violation notices and environmental studies. This research may also include interviews with readily available personnel, such as building managers, tenants and owners.
 
2.1.2.3  Report:  An inspection report is defined as a written communication describing the issues discovered from observations made and research conducted by the inspector that are, in the inspector's opinion, likely to be of interest to his/her client.  A report may contain photographs of observations made during the walk-through survey portion of the inspection and/or copies of documents reviewed during the research portion of the inspection.

There likely exist other standards, codes, local laws, and manufacturers' instructions that differ or are in conflict with this Standard and with each other.  Although this Standard does not require an inspector to know or discover all the provisions that may pertain to every situation, this Standard does require an inspector, if aware of such conflicts, to author the inspection report based on the requirements that provide the greatest protection of life and property, in the inspector's judgment.  This Standard is not intended to usurp or abridge adopted codes or ordinances.
3.3  Substantial Compliance
The inspector shall substantially abide by this Standard, unless otherwise agreed to in writing by the inspector and client.
3.4  Disclaimer of Liability
InterNACHI administers the process in the development of its standards.  InterNACHI does not independently test, evaluate or verify the accuracy of any information or the soundness of any judgments contained in its Standards.  InterNACHI disclaims liability for any personal injury, property or other damages of any nature whatsoever, whether special, indirect, consequential or compensatory, directly or indirectly resulting from the publication, use of, or reliance on this document.  InterNACHI also makes no guarantee or warranty as to the accuracy or completeness of any information published herein.
 
Anyone using this document should rely on his or her own independent judgment, or, as appropriate, seek the advice of a competent professional in determining the exercise of reasonable care in any given circumstances.
4.  Inspection
4.1  Objective
The objective of an inspection is to provide written communication describing the issues discovered from observations made and research conducted by the inspector, which, in the inspector's opinion, are likely to be of interest to his/her client, and to enhance the client's information and knowledge about the commercial property to improve decision-making for buying, selling, maintaining or improving the property.
4.2  Who May Perform the Inspection
Any portion of the inspection, including the walk-through survey, research and report-generation, may be performed by the inspector, his/her staff, or any consultant hired by the inspector.  This Standard recognizes that, for the majority of commercial inspections, the inspector is likely an individual with a general, well-rounded knowledge of commercial properties, and that the inspector or client may want to augment the inspector's skills with specialty consultants who have particular expertise in certain areas.  The decision to hire specialty consultants will, of course, rely on budget and time constraints, as well as the risk-tolerance of the client. 
4.3  Varying Levels of Due Diligence
This Standard is designed as a baseline from which the inspector and client can develop and agree to a scope of work that may deviate from this Standard, depending on budget, time constraints, purpose of the inspection, age of the subject property, and risk-tolerance of the client.  The level of due diligence should be set where the cost, in time and money, of acquiring information about the subject property will not likely exceed the value of that information.  Therefore, an inspection performed in accordance with this Standard will not be technically exhaustive. 
 
4.3.1  Sample Language for Use When Defining the Scope of Work
"The inspection will be performed in accordance with InterNACHIcomsop, except that..."
4.3.2  Representative Observations
In recognizing that the client likely has the goal of acquiring information about the subject property at a cost, in time and money, that does not exceed the value of that information, representative observations are not just permitted by this Standard, but recommended, as well.
4.4  Uncertainty
The client should understand that no inspection report is completely accurate.  A report is only the written communication of the observations made and research conducted by the inspector.  The report contains those items which, in the inspector's opinion, are likely to be of interest to his/her client. 
4.5  Subjectivity
The client should understand that the inspection report is, to a large degree, the subjective opinions of the inspector based on his/her observations and research within the limits of access, time and budget, and without the aid of special equipment or meters, and without dismantling, probing, testing or troubleshooting, and without detailed knowledge of the commercial property, its components or its systems.  The inspection report is not much more than a subjective professional opinion. 
4.6  Not an Architectural or Engineering Service
An inspector performing a commercial inspection in accordance with this Standard is not practicing architecture or engineering.   
4.7  Not a Warranty, Guarantee or Insurance Policy
The inspection is not a warranty, and the inspection report is merely the written communication of the inspector's subjective opinion on the condition of the subject property.
5.  Research
5.1  Objective
The objective of research, including the review of documents and the performing of interviews, is to augment the information obtained during the walk-through survey and to provide supporting documentation to the inspection report. 
5.2  Document Procurement
It is the client's responsibility to obtain copies of all documents and provide them for the inspector.  These documents are most often obtained from the seller or from local government offices.  The inspector is not responsible for gathering or paying for copies of appropriate documents to be reviewed unless these tasks are specifically assigned to the inspector in the Scope of Work Agreement.
5.3  Documents to be Reviewed and Included in the Inspection Report
The inspector should review all documents provided by the client and owner.  The inspector should also make an inquiry and review of any other documents that can be reasonably procured on-site or from the building owner or manager, such as Certificates of Occupancy, building code violation notices, repair invoices, and warranties.  The inspector is not required to uncover and review information that is not provided or cannot be reasonably ascertained or acquired on-site.  Copies of documents that the inspector believes may be of interest to the client and copies of documents that support the inspector's opinions should be included in the inspection report.
 
5.3.1 Examples of documents the inspector may want to request for review:
  • accessibility surveys;
  • appraisals;
  • building plans;
  • Certificates of Occupancy;
  • citations;
  • deck age records, plans and construction permits;
  • deck and balcony maintenance, power-washing, painting, treating, repair and modification history;
  • emergency evacuation plans;
  • environmental studies;
  • evacuation drill records;
  • fire-detection test and maintenance records;
  • fire door inspection reports;
  • fire-prevention plans;
  • fire extinguisher service records;
  • fire records;
  • flame-resistant certificates;
  • floodplain maps;
  • floor plans;
  • kitchen grease-cleaning records;
  • kitchen post-fire inspections;
  • maintenance records;
  • manufacturers' installation instructions;
  • notices;
  • permits;
  • power-washing records;
  • previous inspection reports;
  • proposals;
  • rent records;
  • repair estimates/invoices;
  • safety inspection records;
  • seller disclosures;
  • sprinkler head replacement records;
  • utility bills; and
  • warranties.
5.4  Interviews
The inspector should identify and interview the person(s) with the most knowledge about the condition of the building.  Typically, this will be the building owner or manager.  Unless otherwise agreed to in the Scope of Work Agreement, it is the responsibility of the client to arrange to have such person(s) on hand for interview by the inspector on the day of the walk-through survey. 
5.5  Pre-Inspection Questionnaires
The inspector may request that the owner, building manager and/or client fill out pre-inspection questionnaires to gather information.  The inspector may rely that these responses are truthful.  In cases where parties refuse to fill out questionnaires in writing, the inspector may interview the parties and fill out the questionnaires for them.  The inspector should note in the report if s/he filled out the questionnaire based on an interview and whether such interview was performed in person, by telephone, or by email.  Copies of all responses to such questionnaires should be included in the inspection report. 
5.6  Reliance
The level of accuracy of information varies, depending on its source.  The inspector may rely on information obtained to the extent that the information appears to be accurate and complete.  This Standard does not require the inspector to independently verify the accuracy of the documents reviewed by the inspector or included in the report, nor the statements made by those interviewed by the inspector.
5.7  Fraud
The inspector is not a fraud investigator, and this Standard does not require the inspector to look for intentionally hidden deficiencies in the subject property.  The inspection report is supplementary to the seller's disclosures.
5.8  Previously Generated Reports
A previously generated inspection report should be treated no differently than any other document reviewed during the research portion of the inspection, and, as with information collected from any other source, information obtained from a previously generated report should reference its source in the new inspection report.  No portion of a previously generated report should be used as a substitute for the new inspection report.
6.  Walk-Through Survey
6.1  Objective
The objective of the walk-through survey is to allow the inspector to visually observe the subject property, gather information, and note items of interest.
6.2  Access Responsibility
It is the client's responsibility to arrange for the inspector to receive timely access to the subject property for the walk-through survey portion of the inspection, as well as access to all documents and interviewees needed for the research portion of the inspection.  This includes access to all documents, information and previously generated reports in the client's possession.  The inspector is not responsible for obtaining, reviewing or providing information, should the source withhold, impede or delay access.  Anything that hinders the inspector's access should be noted in the report.
6.3  Revisits
It is expected that the inspector will perform only one walk-through survey per inspection report.  However, it may be necessary for the inspector to revisit certain areas of the subject building after performing the research portion of the inspection.
6.4  Inspector Safety
It is the responsibility of the inspector to perform the walk-through survey safely.

7.  Report
7.1  Format
The report must be in writing.  This Standard does not require any one particular format.  It is InterNACHI's opinion that the commercial inspection industry and consumer clients are best served when inspectors are free to compete through report-generation innovation.
7.2  Date
The report should be dated on the first page.
7.3  Inspection Firm Information
The report should include the name and contact information of the inspection firm on the first or second page.
7.4  Property Address
The report should include the address of the property inspected, or a description of the real estate sufficient for identification, on the first or second page.

7.8  Opinions of Shut-Down Systems
The inspector should still try to render an opinion of the condition of systems even if they were shut down or were not operational at the time of the walk-through survey.
7.9  Obsolescence
The client should only rely on the inspection report at the point in time that the inspector's observations were being made and research was being conducted.  The client should deem the report as obsolete to some extent, even while it is being prepared.
7.10  Site-Specific
The client should understand that an inspection performed in accordance with this Standard only relates to the observations made and research conducted.  Consequently, this Standard does not address issues such as business operations at the subject property, deed encumbrances, neighborhood conditions, etc.
7.11  Multiple Buildings
An inspection report produced in accordance with this Standard may encompass more than one building within a single report.
7.12  Cost to Remedy

ANCILLARY DOCUMENTS 
10.  Commercial Inspection Agreement (between Inspector and Client)
The address of the property is: _________________________________________________________________________.
 
Fee for the commercial inspection is $____________________.   INSPECTOR acknowledges receiving a deposit of $_________________ from CLIENT.
 
THIS AGREEMENT made this _____________ day of _______________________________________________________, 20__, by and between
 
__________________________________________________________ (hereinafter “INSPECTOR”) and the undersigned (hereinafter “CLIENT”), collectively referred to herein as “the parties.”    The parties understand and voluntarily agree as follows:
 
1. INSPECTOR agrees to perform a visual inspection of the commercial building, and to provide CLIENT with a written inspection report identifying the defects that INSPECTOR both observed and deemed material.  Where accessible, INSPECTOR will view a representative sample of the building components covered under this inspection to be used in the preparation of the written inspection report.  INSPECTOR will not test or otherwise analyze elements of the commercial building where destruction or dismantling of the particular element is required.  The primary purpose of the inspection is to enhance the CLIENT’S information and knowledge about the commercial building to improve decision-making for buying, selling, maintaining or improving the property.  As it may relate to this commercial building inspection, INSPECTOR may offer comments as a courtesy, but these comments will not comprise the bargained-for report.  The report is only supplementary to the seller’s disclosures.
 
2. Unless otherwise inconsistent with this Agreement or not possible, INSPECTOR agrees to perform the inspection in accordance with InterNACHI's International Standards of Practice for Inspecting Commercial Properties.  Although INSPECTOR agrees to follow these Standards, CLIENT understands that these Standards contain certain limitations, exceptions and exclusions.  CLIENT also understands that InterNACHI is not a party to this Agreement, and that InterNACHI has no control over INSPECTOR or representations made by INSPECTOR, and does not supervise INSPECTOR.  As noted above, this commercial building inspection is visual only.  In certain instances, INSPECTOR may engage or deploy certain mechanical or other systems in the commercial building for purposes of preparing the written inspection report.  However, it is not possible to engage or deploy many systems in a commercial building, including fire-suppression systems, and, thus, determination of whether such systems are properly functioning or otherwise in need of repair, replacement or maintenance is beyond the scope of this basic commercial building inspection.  The SCOPE OF WORK outlining the specific elements of the commercial building to be inspected by INSPECTOR under this Agreement is attached hereto and incorporated by reference as EXHIBIT A.  Where noted in the written inspection report, INSPECTOR may recommend, and CLIENT acknowledges that such may be necessary, that CLIENT hire a professional engineer, or other qualified and licensed professional, to provide an independent inspection and analysis of certain elements that may be beyond the scope of this basic commercial building inspection.  Unless otherwise indicated below, CLIENT understands that this basic commercial building inspection EXCLUDES compliance with applicable building codes, or testing for the presence of potential dangers arising from asbestos, lead paint, formaldehyde, molds, radon gas, soil contamination, and other environmental hazards or violations.   
 
3. The inspection and report are performed and prepared for the use of CLIENT, who gives INSPECTOR permission to discuss observations with real estate agents, owners, repair persons, and other interested parties.  INSPECTOR accepts no responsibility for use or misinterpretation by third parties.  INSPECTOR’S inspection of the property and the accompanying report are in no way intended to be a guarantee or warranty, express or implied, regarding the future use, operability, habitability or suitability of the commercial building or its components. Any and all warranties, express or implied, including warranties of merchantability and fitness for a particular purpose, are expressly excluded by this Agreement to the fullest extent allowed by law. If any structure or portion of any structure that is to be inspected pursuant to this Agreement is a log home, log structure or similar log construction, CLIENT understands that such structures have unique characteristics that make it impossible for an inspector to inspect and evaluate them by an exterior visual inspection.  Therefore, the scope of the inspection to be performed pursuant to this Agreement does not include decay of the interior of logs in log walls, log foundations or roofs, or similar defects that are not visible by an exterior visual inspection.
 
4.  INSPECTOR assumes no liability for the cost of repair or replacement of unreported defects or deficiencies, either current or arising in the future. CLIENT acknowledges that the liability of INSPECTOR, its agents and employees, for claims or damages, costs of defense or suit, attorney’s fees and expenses, and payments arising out of or related to the INSPECTOR’S negligence or breach of any obligation under this Agreement, including errors and omissions in the inspection or the report, shall be limited to liquidated damages in an amount equal to the fee paid to the INSPECTOR, and this liability shall be exclusive.  CLIENT waives any claim for consequential, exemplary, special or incidental damages, or for the loss of the use of the commercial building, even if the CLIENT has been advised of the possibility of such damages. The parties acknowledge that the liquidated damages are not intended as a penalty, but are intended:  (i) to reflect the fact that actual damages may be difficult and impractical to ascertain; (ii) to allocate risk among the INSPECTOR and CLIENT; and (iii) to enable the INSPECTOR to perform the inspection at the stated fee.
 
5. INSPECTOR does not perform engineering, architectural, plumbing, or any other job function requiring an occupational license in the jurisdiction where the inspection is taking place, unless the inspector holds a valid occupational license, in which case s/he may inform the CLIENT that s/he is so licensed, and is therefore qualified to go beyond this basic commercial building inspection and, for additional fee, perform additional inspections beyond those within the scope of the basic commercial building inspection.  Any agreement for such additional inspections shall be in a separate writing, or noted here: ______________________________________________________________________________________________ _______________________________________________________________________________________________________________________.
 
6.  In the event of a claim against INSPECTOR, CLIENT agrees to supply INSPECTOR with the following: (1) written notification of adverse conditions within 14 days of discovery; and (2) access to the premises.  Failure to comply with the above conditions will release INSPECTOR and its agents from any and all obligations or liability of any kind.  Additionally, if there is a dispute between INSPECTOR and any consultant or third party arising out of INSPECTOR'S inspection, CLIENT agrees to provide INSPECTOR with reasonable access to the premises upon request by the INSPECTOR. 
 
7. The parties agree that any litigation arising out of this Agreement shall be filed only in the Court having jurisdiction in the County in which the INSPECTOR has its principal place of business.  In the event that CLIENT fails to prove any adverse claims against INSPECTOR in a court of law, CLIENT agrees to pay all legal costs, expenses and fees of INSPECTOR in defending said claims.  CLIENT further understands that any legal action against InterNACHI itself, allegedly arising out of this Agreement or INSPECTOR’S relationship with InterNACHI, must be brought only in the District Court of Boulder County, Colorado.
 
8. If any court declares any provision of this Agreement invalid or unenforceable, the remaining provisions will remain in effect.  This Agreement represents the entire agreement between the parties.  All prior communications are merged into this Agreement, and there are no terms or conditions other than those set forth herein.  No statement or promise of INSPECTOR or its agents shall be binding unless reduced to writing and signed by INSPECTOR.  No change or modification shall be enforceable against any party unless such change or modification is in writing and signed by the parties.  This Agreement shall be binding upon and enforceable by the parties and their heirs, executors, administrators, successors and assignees.  CLIENT shall have no cause of action against INSPECTOR after one year from the date of the inspection.
 
9. Payment of the fee to INSPECTOR (less any deposit noted above) is due upon completion of the on-site, walk-through survey portion of the inspection.  The CLIENT agrees to pay all legal and time expenses incurred in collecting due payments, including attorney’s fees, if any.  If CLIENT is a corporation, LLC, or similar entity, the person signing this Agreement on behalf of such entity does personally guarantee payment of the fee by the entity.  If CLIENT requests a re-inspection, the re-inspection is also subject to all the terms and conditions set forth in this Agreement.

CLIENT HAS CAREFULLY READ THE FOREGOING, AGREES TO IT, AND ACKNOWLEDGES RECEIPT OF A COPY OF THIS AGREEMENT.

    EXHIBIT A
    STATEMENT OF WORK
     
    Under this Contract, and as part of this Professional Services Contract, the Inspector and the Consultant agree that the following elements shall be included under this Statement of Work and shall constitute the Services to be performed hereunder:
     

    ______________________________________________________________________________________

    ______________________________________________________________________________________
     
     
    13.  Thermal Imaging Addendum to Commercial Inspection Agreement 
    This is an addendum to the Commercial Inspection Agreement regarding the inspection at: _______________________________________________________________________.
     
    Thermal imaging is a technology that allows the InterNACHI INSPECTOR to show you things about a building that no one can show you using other inspection methods. Thermal imaging produces images of invisible heat energy emitted from objects and systems in the building, and allows us to measure it. Thermal imaging helps to diagnose the problem rather than merely identify symptoms, and can sometimes, but not always, identify and document: electrical faults before they cause a fire; overloaded and undersized circuits; circuit breakers in need of immediate replacement; missing, damaged, and/or wet insulation; heat loss and air infiltration in walls, ceilings, floors, windows and doors; water and moisture intrusion that could lead to mold; possible pest infestation; hidden roof leaks before they cause serious damage; air-conditioner compressor leaks; under-fastening and/or missing framing members; structural defects; broken seals in double-pane windows; energy loss and efficiency; dangerous flue leaks; damaged and/or malfunctioning radiant heating systems; unknown plumbing leaks; and overheated equipment. These color images can then be included in the inspection report, providing supporting documentation to the report.  A picture is worth a thousand words. 
     
    1. CLIENT requests and authorizes INSPECTOR to perform a thermal imaging scan on the structure at __________________________________ for the following purposes:  ___________________________________.  The fee for this additional service will be $_____________, all of which is due prior to delivery of the thermal images.
     
    2. INSPECTOR’s liability for any damages allegedly arising out of any aspect of the thermal-imaging service shall be limited to the additional amount paid for the thermal-imaging scan.  CLIENT voluntarily waives any claim for consequential, exemplary or incidental damages to the fullest extent allowed by law.
     
    3. The thermal-imaging scan will be limited in scope to the equipment used by INSPECTOR.  The inspection will be a non-invasive and non-destructive examination of the visible, safe and readily accessible portions of the interior and/or exterior of the structure for atypical temperature/thermal variations.  NO OTHER WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING, BUT not LIMITED TO, WARRANTIES REGARDING FUTURE USE, HABITABILITY, OPERABILITY, SUITABILITY OR MERCHANTABILITY, WITH RESPECT TO THE SUBJECT PROPERTY, ARE PROVIDED.
     
    4. Thermal-imaging services do not include any inspections, examinations, testing or evaluations for harmful, dangerous or toxic substances, materials or environmental hazards, including, but not limited to: mold; bio-aerosols; radon; lead; asbestos; non-biological airborne particulates; contaminants; petroleum products; petrochemicals; radioactive materials; electromagnetic radiation; or plant, animal or insect secretions or excretions.  Infrared cameras are not moisture meters but can aid in identifying areas that warrant further investigation.  If INSPECTOR offers any information or opinions about any of the foregoing, this information shall be deemed to be informational only and supplied as a courtesy to the CLIENT, and shall not be deemed to be an amendment to this Addendum or the Commercial Inspection Agreement.
     
    5. CLIENT agrees to indemnify and hold harmless INSPECTOR, its agents, employees and inspectors for the presence of any harmful, dangerous or toxic substances or materials, or environmental hazards, including, but not limited to, those listed in Part 4 of this addendum, as well as for any and all damages and liability for any mitigation, construction, or any other costs associated with the presence of any such hazards, substances or materials.
     
    6. If CLIENT desires to obtain information regarding the presence of any harmful, dangerous or toxic substances, materials or environmental hazards, including, but not limited to, those listed in Part 4 of this addendum, it is solely the responsibility of the CLIENT to contact and engage the services of qualified individuals or companies that specialize in the areas of specific interest or concern.  
     
    7.  All of the other terms of the Commercial Inspection Agreement are incorporated herein by reference.
     
    I have carefully read the foregoing and I understand, accept and agree with all of the terms and conditions of this Addendum.

    14.  InterNACHI's Standard Accessibility Inspection Report for Existing Commercial Buildings    
    14.1  About This Accessibility Inspection Report
    Various laws around the world require public accommodations to provide goods and services to people with disabilities on an equal basis with the rest of the general public.  Businesses benefit from the patronage of all people.  Those who own, lease, lease out, or operate places of public accommodation should have as a goal the identification and reduction of physical barriers to this patronage.  This inspection report will help identify possible accessibility deficiencies in existing facilities.
    14.2  Who Must Comply
    Most laws regarding accessibility regulate only new construction and remodeling, and do not oblige existing building owners to reduce barriers if such reduction is not readily achievable.  This report does not cover all of the possible local, state, provincial or federal requirements regarding accessibility or barrier reduction.  The information presented within this report was derived from a visual-only inspection of the property, and is intended solely as informal guidance, and is not a determination of legal rights or responsibilities. 
    14.3  Stand-Alone Inspection Service Option
    This report may be offered in conjunction with a complete commercial property inspection, or offered as a separate, stand-alone inspection service.

    15.  InterNACHI's Observed Green Features Report for Existing Commercial Buildings
    15.1  Definition of "green"
    “Green” describes features, technologies and products that increase efficiency in a building’s energy and water usage, help protect the health of its occupants, and reduce the commercial property’s impact on the environment.  Green buildings are healthier, more environmentally friendly, and economically smarter than average buildings. 
     
    Green features:
    • improve energy efficiency;
    • reduce pollution;
    • provide healthier air;
    • increase comfort;
    • reduce water usage;
    • preserve natural resources;
    • increase durability;
    • make a building quieter;
    • reduce maintenance;
    • lower monthly costs; and
    • improve resale value.
    15.2  Codes and Standards
    Nearly all green building codes and standards have been developed by private organizations and pertain to new construction, not existing commercial properties.  Nevertheless, many existing properties, by design, by luck, or through modification, have green features that clients should know about.
    15.3  Purpose
        This Standard does not require the inspector to determine the “green-ness” of a building. The purpose of the Green Features Report is to permit the inspector to easily point out common green features of the property, thus increasing client awareness of the property's green features. The inspector is not required to perform an energy audit, determine code compliance, perform environmental assessments, test for radon, lead, asbestos or mold, or report on all green features or the lack of them (see Section 8:  Limitations, Exceptions and Exclusions).
    15.4  Optional Add-On Inspection Service
      This Standard does not require the inspector to perform this green features inspection.  The Observed Green Features Report may be offered in conjunction with a complete commercial property inspection, or as a separate, stand-alone inspection service.
      15.5  Green Checklist
      The following checklist is designed to help identify commonly found green features noticed by the inspector.
       
                       ____________________________________________

    Key:

        Y = Yes. This feature was observed and may exist.
        N = No. This feature was not observed and so might not exist.
        U = Unknown. Inspector did not note.
        N/A = Not applicable.
        * = May be implemented in existing properties.

    16.  International Standards of Practice for Inspecting Commercial Fire Doors

    16.1  About These Standards for Inspecting Commercial Fire Doors

    Many buildings, including schools, high-rises, healthcare facilities, churches, office buildings, factories and warehouses are likely to have fire doors.  Should a fire occur, the health, safety and welfare of building occupants and emergency responders depend on the regular inspection of fire doors.

    16.2  Purpose

    The purpose of this document is to establish international standards for the inspection of commercial fire doors.  This document also provides a universal commercial fire door-inspection reporting form.

    16.3  Definitions
    16.3.1  Fire Door-Specific Definitions
  • active leaf:  the door of a pair of swinging doors that is normally used.
  • automatic closing device:  a device that causes the door to close when activated by a fusible link or heat-actuated device.
  • barrel:  a cylindrical part of a rolling steel fire door that contains the counter-balance springs.
  • bottom bar:  the lower edge of the door assembly.
  • coordinator:  a device used on pairs of swinging doors that causes the inactive leaf to close before the active leaf.
  • flame baffle:  a hinged piece of sheet metal that closes the space between the top of a rolling steel fire door and its hood.
  • fusible link:  a device consisting of pieces of metal held together by solder that melts during a fire.
  • hood:  a sheet metal housing that contains the rolled door.
  • inactive leaf:  the door of a pair of swinging doors that is normally latched.
  • non-combustible:  not capable of igniting when subjected to fire.
  • sill:  the bottom part of a doorway opening; threshold.
  • 16.3.2  Terminology Commonly Found in Commercial Property Inspection Reports

    16.4  Goal of the Inspection

    The goal of a commercial fire door inspection is to provide an indication as to whether the door is in a state of readiness to perform its intended function during a fire. 

    16.5  Limitations

    It is not the purpose of this Standard to establish inspection procedures to:  determine the fire rating or the degree of protection provided by a fire door or surrounding wall; determine the need for a fire door in any particular location; determine proper placement of detectors; determine the functionality of fire-detection systems; heat-test fusible links; determine the combustibility of floor coverings extending through doorways; inspect accordion, folding, hoistway, elevator, chute, access or dumbwaiter doors; inspect fire windows; or inspect fabric fire-safety curtains.

    16.6  Optional Add-On Inspection Service
    InterNACHI's Standards of Practice for Inspecting Commercial Properties does not require the inspector to perform fire door inspections.  The fire door inspection may be offered in conjunction with a complete commercial property inspection or as a separate, stand-alone inspection service.  

    16.7  Inspection Frequency

    Fire doors should be inspected after any incidents that may have damaged the door or its components, or upon noticing possible damage, but not less than annually.

    16.8  Visual Inspection

    16.8.1  The inspector should visually inspect from both sides of the door assembly.

    16.8.2  The inspector should inspect the door opening and surrounding area for potential obstructions, items or conditions that might interfere with the free operation of the door.

    16.8.3  The inspector should inspect for auxiliary items that could interfere with door operation.

    16.8.4  The inspector should inspect for missing or insecure mounting and assembly bolts.

    16.8.5  The inspector should inspect for evidence of field modifications that may void the door’s fire rating.

    16.8.6  The inspector should inspect for open holes or breaks that exist in either the door or frame.

    16.8.7  The inspector should inspect for failed glazing or glazing beads that are not intact or securely fastened.

    16.8.8  The inspector should inspect for missing or broken parts.

    16.8.9  The inspector should inspect for combustible sills.  Sill should be non-combustible.

    16.8.10  The inspector should inspect for clearances of swinging doors between the top and vertical edges of the door and the frame, and the meeting edges of doors swinging in pairs, measured from the pull-side of the door, that exceed 1/8-inch (3.18 mm) + 1/16-inch (1.59 mm) for steel doors, and + 1/8-inch (3.18 mm) for wood doors.

    16.8.11  The inspector should inspect for clearances of swinging doors under the bottom of the door that exceed ¾-inch (19 mm), and 3/8-inch (9.5 mm) for doors that have sills more than 38 inches (965 mm) above the finished floor (such as repair counters).

    16.8.12  The inspector should inspect the opening of sliding doors at the sides and top for overlaps that are less than 4 inches (102 mm).

    16.8.13  The inspector should inspect and note whether combustible floor coverings extend through the door opening, although, depending on the rating of the door, some combustible floor coverings are permitted to extend through door openings.  Determining compliance lies beyond the scope of a commercial fire door inspection.  Combustible flooring should never extend through doorways protected by three-hour (or greater)-rated fire doors.

    16.9  Operational Check

    16.9.1  Before checking, the inspector should identify anything that might create a hazard during the operational check.  If, in the opinion of the inspector, a hazard might be created by operating the door, the inspector shall not perform the operational-check portion of the inspection.

    16.9.2  The inspector should open and close the door using normal operation.  Doors should open and close easily.

    16.9.3  The inspector should inspect the condition of any gaskets or edge seals.

    16.9.4  The inspector should inspect the guides and bearings for lack of lubrication.

    16.9.5  The inspector should inspect for blocking or wedging of doors in the open position, or blocked or wedged release arms and weights of sliding and rolling doors.

    16.9.6  The inspector should inspect for kinked, pinched, twisted, or excessively worn chains or cables of sliding and rolling doors.

    16.9.7  The inspector should inspect the condition of any fusible links and heat–actuated devices (if equipped).  Links should not be painted or coated with dust or grease.

    16.9.8  The inspector should inspect signs installed on the surface of the fire door for interference with the proper operation of the door.

    16.9.9  The inspector should inspect for signage that exceeds 5% of the total area of the face of the fire door to which it is attached.

    16.9.10  The inspector should inspect for signs that are attached by mechanical means, such as screws or nails.  Signs should be attached to fire doors by the use of adhesive only.
     
    16.9.11  The inspector should inspect for rating and inspection labels and tags that have been painted over.  Labels and tags should not be painted over. 

    16.10  Simulation (Drop) Test

    16.10.1  Before testing, the inspector should identify anything that might create a hazard during testing.  If, in the opinion of the inspector, a hazard might be created by testing, the inspector shall not perform the testing portion of the inspection.

    16.10.2  The inspector should perform all testing and re-setting of the release mechanism in accordance with the manufacturer’s instructions.  If instructions are not made available at the time of the inspection, the inspector should continue only if s/he has knowledge and understanding of the operating components of that type of door.

    16.10.3  The inspector should inspect for missing closing devices (self-closing or automatic).  Every fire door should have a closing device.

    16.10.4  The inspector should test any self-closing devices of swinging doors to assure that they close and latch the door completely when operated from the fully-open position.

    16.10.5  The inspector should inspect closing mechanisms of swinging doors for hold-open features.  Closing mechanisms should not have hold-open features unless they are on doors that are designed to automatically close during an alarm condition.

    16.10.6  The inspector should test any coordinators of dual-leaf doors for failure to close the inactive leaf before the active leaf.  A coordinator is not needed where each door leaf closes and latches independently of the other.

    16.10.7  The inspector should inspect for latching hardware that fails to operate or fails to secure the door when it is in the closed position.

    16.10.8  The inspector should inspect for normal operation and full closure of sliding and rolling doors with an initial simulation (drop) test.

    16.10.9  The inspector should inspect the closing for speeds slower than 6 inches per second (152 mm/sec.), or faster than 24 inches per second (610 mm/sec.).

    16.10.10  The inspector should perform a second simulation (drop) test of sliding and rolling doors to verify that the automatic closing device has been re-set.

    17.  International Phase I Standards of Practice for Inspecting Fireplaces and Chimneys
    17.1  About These Standards for Inspecting Fireplaces and Chimneys
    Although this Standard applies to both commercial and residential fireplaces and chimneys, it exceeds the requirements of both InterNACHI’s Commercial and Residential Standards of Practices. The inspection shall include examination of readily accessible and visible portions of solid-fuel-burning, low-heat fireplaces and chimneys. 
    17.2  Purpose
    The purpose of this document is to establish international standards for the inspection of fireplaces and chimneys. This document also provides universal fireplace and chimney inspection reporting language.

    • connector:  the pipe that connects a fuel-burning appliance to a chimney.
    • crown:  the sloped top of a masonry chimney designed to shed water away from the flue; also called a splay or wash.
    • damper:  a manually operated plate for controlling draft in a flue.
    • fireplace lintel:  a horizontal, non-combustible member that spans the top of the fireplace opening.
    • flue:  a passage through which gases move from the fire chamber to the outer air.
    • hearth:  the floor within a fireplace.
    • hearth extension:  non-combustible material in front of and at the sides of a fireplace opening.
    • mantel:  a shelf or horizontal ornament above a fireplace opening.
    • Phase I:  a type of fireplace and chimney inspection that exceeds the standards required by a traditional home inspection.
    • single-wall metal chimney:  a field-constructed chimney not permitted in one- and two-family dwellings.
    • solid fuel:  wood, coal, pellets, and other materials that can be burned for heat.
    • thimble:  the tube or lining through a wall that a connector passes through to enter a flue or that a flue passes through to exit a roof. 
    • wall protector:  non-combustible shield between a wall and anything heat-producing for the purpose of reducing the required clearance. 
    17.3.2  Terminology Commonly Found in Commercial Property Inspection Reports
    17.4  Goal of the Inspection
    The goal of the inspection is to provide observations which may lead to the decrease of hazardous conditions associated with fireplaces and chimneys.  
    17.5  Limitations
    The inspection is limited to readily accessible and visible portions of the fireplace and chimney.  The inspection should not be considered all-inclusive or technically exhaustive. 
     
    This Standard does not require the inspector to:
    • inspect appliances, wall furnaces, stoves, water heaters, incinerators, mechanical draft systems, draft regulators, catalytic converters, pollution-control devices, heat-reclamation devices, spark arrestors, induced-draft chimneys, fire-stopping, or for condensation issues.  
    • determine fire rating, adequacy of combustion air, status of product listing, compliance with manufacturers' instructions, proper clearances, proper load paths, combustibility, proper placement of flue size changes, proper thimble installation, or repair history.  
    • remove or inspect fireplace inserts, stoves or accessories.
    • determine the need for fire-stopping, chimney enclosures, hearth thickness mitigation, or seismic reinforcing.  
    • test smoke detectors or carbon-monoxide detectors.
    • perform video scans, smoke tests, flue-gas measurements, or engineering calculations. 
    These Standards do not apply to the inspection of mobile homes. 
    17.6  Optional Add-On Inspection Service
    Although InterNACHI's Standards of Practice for Inspecting Commercial Properties and InterNACHI’s Standards of Practice for Performing a General Home Inspection do not require the inspector to perform a Phase I Fireplace and Chimney Inspection, it may be offered in conjunction with a complete commercial or residential property inspection, or as a separate, stand-alone inspection service. 
    17.7  Inspection Frequency
    The inspector should advise his/her client that all fireplaces and chimneys should be inspected prior to the client's first use, and not less than annually.
    17.8  Visual Inspection
    17.8.1  Initial Inspection

    17.8.5.2  The inspector should inspect for chimneys that terminate less than 3 feet above the highest point where they pass through the roof surface.
     
    17.8.5.3  The inspector should inspect for chimneys that terminate less than 2 feet above any portion of a building (ridge, wall or parapet) within 10 feet.
     
    17.8.5.4  The inspector should inspect for chimneys that terminate less than 3 feet from adjacent buildings or building openings.
     
    17.8.5.5  The inspector should inspect for chimneys that terminate less than 10 feet above grade or walkways.
     
    17.8.5.6  The inspector should inspect for chimney outlets that jeopardize people, overheat combustible structures, or that might cause flue gases to enter nearby building openings.
     
    17.8.5.7  The inspector should inspect the crowns of masonry chimneys for slopes that direct water into flues.
    17.8.6  Flues and Liners

    17.8.6.5  The inspector should inspect for liners that are visibly softened, cracked, deteriorated or damaged.
     
    17.8.6.6  The inspector should inspect readily accessible and visible flues and liners for excessive accumulation of creosote, soot, or other combustible material.
     
    17.8.6.7  The inspector should inspect for flues that have two or more openings at the same level.
     
    17.8.6.8  The inspector should inspect for venting into the space around and between liners.  The remaining space surrounding a chimney liner should not be used as a vent.
    17.8.7  Flue Size 
    The inspector should inspect the size of the flue, if visible, and compare it to the size of the fireplace opening. This relationship is the most important factor in achieving sufficient draft.  A flue that is too small relative to the fireplace opening will be unable to lift and remove hazardous flue gases to the outside.

    18.  International Standards of Practice for Inspecting Radon-Mitigation Systems
    18.1  About Radon and These Standards for Inspecting Radon-Mitigation Systems
    Radon is a radioactive gas that has been found in homes, schools and buildings around the world.  Radon comes from the natural breakdown of uranium in soil and rock, and moves up into the indoor air that people breathe.  Radon is the leading cause of lung cancer in non-smokers.  Radon-mitigation systems reduce radon levels in homes and buildings.  Inspection of these systems helps assure that they were installed properly and are performing as designed.
     
    Although this Standard applies to both commercial and residential radon-mitigation systems, this Standard exceeds the requirements of both InterNACHI’s Commercial and Residential Standards of Practices.
    18.2  Purpose
    The purpose of this document is to establish international standards for the inspection of radon-mitigation systems.  This document also provides universal radon-mitigation inspection reporting language.
    18.3  Definitions
    18.3.1  Radon-Mitigation System-Specific Definitions
    • active soil-depressurization system:  one or more of the following types of radon-mitigation system types involving mechanically driven soil depressurization:  sub-slab depressurization; sump (pit) depressurization; drain-tile depressurization; sub-membrane depressurization; hollow-block wall depressurization; and crawlspace depressurization.
    • crawlspace depressurization:  an active radon-mitigation system that lowers the air pressure inside a crawlspace in relation to the rooms adjacent or above the crawlspace.  A fan draws air directly from the air space of the crawlspace and discharges the air outside.  This type of system is typically not the best choice because of the great potential for appliance back-drafting and energy loss.
    • defect:  a condition of a radon-mitigation system that may have an adverse impact on its performance.
    • depressurization:  a negative pressure created in one area compared to an adjacent area.
    • discharge:  the end of a vent stack pipe open to outside air.
    • drain-tile depressurization:  an active soil-depressurization system whereby a suction point is located at a drain tile.
    • heat-recovery ventilation (HRV) system:  a system that lowers radon levels by using outside air to dilute and pressurize indoor air.  HRV systems are considered active radon-mitigation systems.
    • hollow-block wall depressurization:  an active radon-mitigation system that depressurizes the open spaces within concrete block foundation walls.
    • inspection:  a non-invasive, visual examination of a radon-mitigation system.
    • manifold pipe:  pipe between a vent stack pipe and suction-point pipe with two or more suction points.
    • radon-mitigation system:  any system designed to reduce the radon concentrations of indoor air.
    • radon system piping:  the piping of a passive or active radon-mitigation system that is composed of a suction-point pipe, manifold pipe, and vent stack pipe.
    • readily accessible:  a system or component that is, in the judgment of the inspector, capable of being safely observed without the removal of obstacles, detachment or disengagement of connecting or securing devices, or other unsafe or difficult procedures to gain access.
    • sub-membrane depressurization:  an active radon-mitigation system creating  low air pressure under a vapor retarder.  A common example is when a vapor retarder (polyethylene plastic sheet) is installed over the exposed dirt floor of a crawlspace.  The radon fan draws air from below the vapor retarder and sends it outside.
    • sub-slab depressurization (active):  a radon-mitigation system that creates low air pressure under a concrete floor using a fan.
    • sub-slab depressurization (passive):  a radon-mitigation system that creates low air pressure under a concrete floor without the use of a fan.
    • suction point:  the end of a radon-mitigation system that penetrates the slab, wall, vapor barrier, sump cover, or drain tile.
    • sump (pit) depressurization system (active):  a radon-mitigation system that has a suction point installed in the sump (pit).
    • vent stack pipe:  pipe leading from the suction point (in a system with a single suction point) or the manifold pipe (in a system with more than one suction point) to outside air.  In active radon-mitigation systems, the radon fan is installed vertically in the vent stack pipe.
    18.3.2  Terminology Commonly Found in Commercial Property Inspection Reports
    18.4  Goal of Inspection
    The goal of the inspection is to provide observations which may indicate that a radon-mitigation system was installed improperly, is not performing as designed, or is in need of repair.
    18.5  Limitations
    The inspection is limited to readily accessible and visible portions of the radon-mitigation system.  The inspection should not be considered all-inclusive or technically exhaustive.  It is not a substitute for a radon level measurement.
     
    This Standard does not require the inspector to:
    • inspect any portion of the system that is not readily accessible and visible.
    • activate a system that has been turned off, unplugged or deactivated.
    • measure the radon level.
    18.6  Optional Add-On Inspection Service
    Although InterNACHI's Standards of Practice for Inspecting Commercial Properties and InterNACHI’s Standards of Practice for Performing a General Home Inspection do not require the inspector to perform radon-mitigation system inspections, one may be offered in conjunction with a complete commercial or residential property inspection, or as a separate, stand-alone inspection service.
