Different types of structures have different inspection needs. Single-family homes need to be sound so you and your family can enjoy them for decades to come, ideally with little more than routine maintenance.

Commercial buildings, such as apartment buildings, duplexes, co-ops and condos have additional needs. These buildings need to be comfortable for tenants, but they also need to be up to current building codes, to limit the owner's liability and ensure the safety of those who live there. Generally, multi-family dwellings are held to a higher standard than single-family homes. Buildings used for commerce, such as warehouses and storefronts, have even more potential issues, such as air quality.

A good home inspector, who has experience with multi-family and commercial buildings, can help you to evaluate whether a particular building is really a good investment.
