Does a home inspector test all the wall switches in a house?

Thursday, October 1, 2020

The Standards of Practice of both the national home inspector associations require an inspector to examine a “representative number” of wall switches in a home, not all of them. The American Society of Home Inspectors (ASHI) defines a representative number as “one component per room for multiple similar interior components such as windows and electric receptacles; one component on each side of the building for multiple similar exterior components.”  The International Association of Certified Home Inspectors (InterNACHI) uses a simpler definition: “A number sufficient to serve as a typical or characteristic example of the item(s) inspected."
