Livonia R-1 districts limit total building coverage to 25 percent of lot area, with additional impervious surface limits. Exceeding coverage requires a variance or a stormwater management plan.
The Livonia Zoning Ordinance caps building coverage in R-1 single-family residential districts at approximately 25 percent of the lot area, including the principal dwelling plus any detached accessory structures. Some districts apply stricter maximums for larger estate lots and more permissive rules for small R-7 parcels. Beyond building footprint, the city regulates total impervious coverage through the stormwater ordinance, which requires new development exceeding certain impervious thresholds to provide on-site detention or infiltration to limit runoff to Rouge River tributaries. Rear yard coverage by accessory structures is also capped, typically at 30 percent of the rear yard, to preserve open space. Homeowners planning additions, large patios, pools, or detached garages should verify coverage at the permit stage. Variances are heard by the Zoning Board of Appeals, which expects demonstration of practical difficulty and proof that drainage and neighbor impacts are managed.
