Michigan's housing stock is old. In Detroit and many of its surrounding communities, the median home age sits well above the national average, meaning buyers are often looking at construction from the 1910s through 1950s. That's not a problem in itself, but it does mean inspections regularly uncover lead paint, knob-and-tube wiring, aging cast iron drains, and foundation issues that wouldn't appear in a 1990s-built suburban home.
The other major factor is water. Michigan sits in the Great Lakes region with significant precipitation and soil that retains moisture. Basement water infiltration is the most common finding in inspections across the state, from Detroit to Traverse City to Kalamazoo. Buyers who've only purchased homes in drier climates are often surprised by how consistently moisture shows up in Michigan reports.
Radon is also a concern. Michigan has areas of elevated radon potential, particularly in the southern Lower Peninsula. The Michigan Department of Environment, Great Lakes, and Energy recommends radon testing for homes in affected areas. Many buyers add a radon test to their standard inspection package.
Michigan requires home inspectors to be licensed through the Department of Licensing and Regulatory Affairs (LARA). When hiring an inspector, verify their license is current and ask about their experience with the specific era and type of home you're purchasing. An inspector who specializes in new construction may not be your best choice for a 1920s Detroit bungalow.
Common Michigan Considerations
- Basement water infiltration
- Lead paint in pre-1978 homes
- Knob-and-tube wiring
- Aging cast iron plumbing
- Radon in southern Lower Peninsula
- Deferred maintenance on older housing stock
Local Requirements: Home inspectors licensed through Michigan LARA. Michigan follows its own statewide building code with local amendments in some jurisdictions.
