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

Warren's R-1-A One Family Residential District, the city's primary single-family zone under Article V of the Zoning Ordinance, caps building footprint as well as setbacks. 03 could therefore support roughly 3,294 square feet of combined building footprint under the strict 30 percent ceiling. 11(7) for the churches, synagogues, mosques, public schools, public libraries, funeral homes, community buildings, country clubs, and fraternal lodges the Planning Commission may approve in residential districts, layered on top of that section's own half-acre minimum site size and 100-foot lot width.

01(i) separately restricts to no more than 700 square feet of floor area regardless of how much coverage allowance remains. Coverage is checked at the building-permit stage by the Department of Buildings and Safety Engineering, and a structure built beyond the cap is subject to the same municipal civil infraction process as other zoning violations: a zoning inspector may cite the property under Section 1-11(b)(5), with fines of $100 to $1,000 per violation under Section 1-8(b), plus each day of noncompliance counted as a new offense.
