Lot coverage limits in San Diego are established by zone in the development regulation tables of the Land Development Code (Tables 131-04C through 131-04G). Coverage varies by zone from approximately 50-60% for single-family zones to higher percentages for multi-family zones. ADUs of 800 sq ft or smaller are exempt from lot coverage calculations. Guest quarters and non-habitable accessory structures are permitted in addition to ADUs.
San Diego 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.
