InterNACHI Well case studies

InterNACHI Well · Put your knowledge to work in context.

The InterNACHI Well credential is aimed at home and building inspectors who want to extend their practice from code-minimum and structural concerns into occupant health and wellness. Where a conventional inspection asks whether a building is safe and sound, a well-focused inspection asks whether the people inside it can breathe, see, hear, hydrate, and move comfortably. The InterNACHI Well case studies are 5 cases and about 4,393 words.
