Genesee County sets no countywide lot-coverage limit. The maximum share of a lot you can build on is set by your city or township zoning ordinance and district.
Maximum lot coverage—the percentage of a parcel that buildings may occupy—is set locally under the Michigan Zoning Enabling Act, not by Genesee County. Residential districts often cap coverage around 25–35% of the lot, with separate limits on total impervious surface and on accessory-building footprint. Denser and commercial districts allow more. These standards protect drainage, light, and open space, and tie into the Genesee County Drain Commissioner's stormwater rules on larger sites. Grand Blanc and other Genesee County municipalities list coverage limits in their zoning ordinance dimensional schedules. Check your parcel's zoning district for the exact maximum before adding a structure or paving.
Exceeding lot coverage means a denied permit or a required variance from the local zoning board of appeals; over-building can force removal. The county sets no coverage cap.
