Maximum lot coverage in Yonkers varies by zoning district: roughly 25-30% in R-1 (lowest-density single-family), up to 40-50% in denser R-4/R-5 districts. Accessory structures count toward coverage.
Yonkers Zoning Ordinance Chapter 43 establishes district-specific maximum lot coverage: R-1 (lowest density detached) typically 25%, R-2 around 30%, higher-density R-3/R-4/R-5 up to 40-50%. Coverage includes the footprint of all buildings (primary and accessory). Impervious surface coverage (patios, driveways) is separately regulated in some districts. Coverage calculations affect additions, new accessory structures, and ADUs. Existing non-conforming coverage may be maintained but not expanded without variance.
Exceeding coverage: zoning denial of permit. Construction over limits requires variance or removal.
