Lot coverage in Downey is regulated by zone. No building may occupy a greater percentage of lot area than specified for its zone. Open space required for one building cannot count toward another.
Downey zoning code limits maximum lot coverage, defined as the percentage of a lot covered by buildings, driveways, patios, and other impervious surfaces. Typical residential limits are 40 to 60% depending on zoning district and lot size. Lot coverage calculations include primary structures, accessory buildings, paved areas, and covered patios. Permeable pavers may receive partial credit in some jurisdictions. Exceeding lot coverage requires a variance. Stormwater management requirements may apply to highly impervious lots.
Exceeding lot coverage: correction required. May need to remove impervious surface. Fines $200 to $1,000.
