What Is a Certificate of Occupancy?

A COO is issued by a local building or code enforcement department confirming a dwelling is safe and legal to occupy under that municipality's codes. It is not one universal Michigan standard, each city sets its own process.

Municipal Variation

When a COO Matters

COO requirements often surface with new construction, major renovations, change of use, or rental conversions. Some cities require updated COO documentation at transfer; others do not.

Pair this overview with our Point-of-Sale Inspection guide, many municipalities use both concepts in sell-side compliance.

Before Listing

Seller Preparation

  • Ask your municipality whether COO documentation is required at sale
  • Resolve open permits or code violations before listing when possible
  • Disclose unpermitted work honestly. Surprises kill deals at inspection
  • Coordinate with your agent on timeline if COO reinspection is needed
