Irvine's Zoning Code sets maximum lot coverage by planning area and zoning district. Lot coverage includes all structures on the property. As a master-planned community, lot coverage standards are designed to maintain the intended character of each neighborhood. Impervious surface coverage may be separately regulated for stormwater purposes. Exceeding limits requires a variance.
Irvine 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.
