Home Inspection Industry Statistics

With 2.1 million home inspections performed annually and a median cost of $333, the real surprise is that 18% of inspections flag safety issues that need remediation or further evaluation, from ventilation and guarding to electrical hazards. This page connects the demand drivers, including radon exposure and owner repair problems, to practical practices that improve results, such as 3.2x higher review response when inspectors use automated SMS reminders after the visit.

Home inspections remain a constant part of buying and maintaining a home, with InterNACHI estimating 2.1 million inspections performed annually in the United States. Yet the most revealing part is what happens after the report, where 18% of inspections flag safety related issues needing remediation or further evaluation and 4% lead to add on requests beyond the standard scope. From photo heavy digital reporting to radon and electrical risk trends, these industry numbers explain why one inspection can turn into multiple follow up steps for real households.
