Send Data to InterNACHI:

License applicants must have their supervising home inspector submit to Moranda Evans at the "5 Field Inspection Events" form. This step is critical. Without sending proof of your 5 Field Inspection Events to InterNACHI, we can not confirm your licensing data with the state.
