Do I need a permit for water damage repairs in Michigan?

The two phases of a water loss sit on opposite sides of the permitting line. Mitigation is damage control — removing water, running drying equipment, demolishing unsalvageable materials — and is treated as emergency work, not construction. Reconstruction is construction: replacing framing or subfloor, rewiring circuits that got wet, re-running supply lines, installing new drywall at scale, or replacing a water heater or furnace all commonly trigger permit requirements under Michigan’s construction codes, with the specifics varying by municipality — Sterling Heights, Troy, and Warren each administer their own building departments.

Two practical protections for homeowners. First, Michigan requires a licensed Residential Builder for reconstruction work performed for compensation — verify any contractor’s license on the state LARA lookup before signing a rebuild contract. Second, the contractor should pull the permits, not you: an owner-pulled permit can shift code-compliance responsibility onto the homeowner, and a contractor who asks you to pull the permit for their work is waving a flag.

Why it matters beyond legality: unpermitted electrical and plumbing work surfaces at the worst times — home sale inspections, appraisals, and future insurance claims, where an uninspected repair in the loss chain complicates everything. On insurance-paid rebuilds, permit fees are a normal documented cost of the reconstruction scope. Prime Restoration rebuilds under Michigan Residential Builder license #262500491 and handles permitting as part of the reconstruction phase; confirm local specifics with your city’s building department, and consult your carrier on scope questions.
