Michigan has a housing stock that skews older than most of the country, with a large proportion of homes built between 1940 and 1975. Those homes were built with materials and techniques that were standard at the time, which means a lot of Michigan homeowners are working around plaster-over-lath that previous owners patched with drywall, undersized vapor barriers, and wall assemblies that weren't designed with today's understanding of moisture management.
The climate is genuinely hard on interior finishes. Michigan winters bring temperatures that regularly dip below zero in the northern half of the state, and the freeze-thaw cycle drives seasonal movement in foundations and framing that shows up as cracking every spring. The summers are humid enough, especially near the Great Lakes, that moisture intrusion into basements and crawl spaces is a persistent problem.
The good news for Michigan DIYers is that the construction industry here is well-supplied and the drywall material costs are reasonable compared to coastal markets. A sheet of 1/2-inch standard drywall runs about the same as anywhere in the Midwest, and the labor market for contractors, while tight in metro areas, is more accessible than in high-cost cities.
Common Michigan Considerations
- Freeze-thaw cracking at door and window corners from seasonal foundation movement
- Basement moisture intrusion through block or poured walls in older homes
- Plaster patched with drywall in inconsistent ways by previous owners
- Nail and screw pops in spring after framing dries from winter moisture absorption
- Condensation and mold in poorly insulated exterior walls
Local Requirements: Michigan follows the Michigan Residential Code, which is based on the International Residential Code with state-specific amendments. The Michigan Department of Licensing and Regulatory Affairs (LARA) oversees building codes. Type X fire-rated drywall is required in attached garage ceilings and walls per code.
