Michigan environmental factors
Building for Michigan's conditions.
Three things shape Michigan home improvement costs more than anywhere else: frost-line depth, snow load on roofs, and an old housing stock with hidden plumbing and electrical surprises. Plan for them and your project comes in on budget.

What shapes a Michigan project
Deck footings, porch piers, and any permanent outdoor structure must extend below this depth. Skipping it means the structure heaves and fails inspection.
Roof structures, additions, and screened porches must be designed for these loads. Old roofs may fail the load calculation when you re-shingle or add solar.
Plan for ice-and-water shield extending 24 inches past the inside wall line on any re-roof. Add ridge and soffit vents during the same project.
Expect to encounter galvanized supply lines, knob-and-tube wiring, 60-amp panels, and asbestos floor tiles in pre-1980 builds. Budget 12–15% contingency for surprises.
Sump pumps and exterior drainage matter more in Michigan than in dry climates. Factor this into any basement remodel or finishing project.
EPA RRP rules apply to any contractor touching painted surfaces in pre-1978 homes. Adds $300–$800 to most painting and renovation projects.
