IAC2’s standards clearly lay out the ground rules for home inspectors when confronting mold; the standards make it clear, among other things, that a mold inspection is not a home inspection, nor should it be considered a proper indoor air quality inspection.
“A mold inspection,” according to IAC2’s standards, “is a non-invasive visual examination of a building to identify and report on conditions that have led to water intrusion, water damage and conditions conducive to microbial growth.”
The inspector is not required, for example, to enter the attic, touch insulation or walk on the roof during a mold inspection. On the other hand, an inspector is required to inspect visible duct work, gutters and the ventilation of attic spaces, to name just a few requirements.
The standards indicate that a mold inspection is not “technically exhaustive” and is not designed to find concealed or latent defects in the house. Mold inspectors should also know that IAC2’s standards only apply to housing structures with four or fewer dwelling units.
