According to the ASHI standards, how many interior doors should be operated during an inspection?

The correct answer is based on the guideline that emphasizes inspecting a representative number of interior doors during a home inspection. Operating ideally one door per room allows the inspector to assess the functional operation of doors while also examining aspects such as the condition of door frames, the integrity of door hardware, and any potential issues related to accessibility or security. This approach provides a sufficient sampling of the home's interior door conditions without being overly exhaustive, which aligns with the efficient and practical nature of home inspections as outlined by ASHI standards.

The focus on a representative sampling rather than inspecting all doors or just a minimum number reflects the need to balance thoroughness with efficiency in inspections. Each room's door can reveal important information about the house's functionality and safety, ensuring a comprehensive assessment within reasonable time constraints.
