Wyoming, MI Building Setbacks & Zoning: Lot Coverage Limits (2026)

Lot coverage is defined at Sec. 90-212(4) as 'the part or percent of the lot occupied by buildings or structures, including above ground accessory buildings or structures such as decks and porches,' so attached decks and porches count against the cap even though they are not fully enclosed. Chapter 90's Article 4A development-standards tables set the residential ceiling at 35 percent for the R-1, R-2 and R-3 Residential Districts (Sec. 90-403A, 90-408A and 90-413A) and the ER Estate Residential District, rising to 40 percent in the R-4, R-5 and R-7 Residential Districts (Sec.

90-419A and neighboring sections). Article 4B carries the same 40 percent ceiling into the B-1 Local Business, B-2 General Business, B-3 Planned Shopping Business and RO-1 Restricted Office Districts, and into the PUD-1 and PUD-2 Planned Unit Development Districts under Article 4C. The city's three industrial districts get the most room: I-1 Light Industrial (Sec. 90-427B), I-2 General Industrial and I-3 Restricted Industrial all cap coverage at 50 percent, though I-1 also requires a 43,560-square-foot (one-acre) minimum lot and 100-foot minimum width. Sec. 90-104 makes the zoning chapter mandatory citywide: 'No building, structure or land shall be used or occupied, and no building or structure or part thereof shall be erected, moved, placed, reconstructed, extended, enlarged or altered, except in conformity with this chapter,' which is how the planning and building departments enforce the coverage cap at the building-permit stage.

These figures apply strictly inside the City of Wyoming, Kent County; they do not extend into neighboring Grand Rapids, Kentwood, Grandville or Byron Center, each of which sets its own zoning table.
