Lot coverage limits in unincorporated San Diego County are set by the Zoning Ordinance. Coverage typically ranges from 25% to 60% depending on zone. ADUs up to 800 sq ft are exempt from lot coverage calculations per state law.
The County Zoning Ordinance establishes maximum lot coverage percentages for each zone. Rural zones typically allow 25-35% coverage, semi-rural zones 35-50%, and village residential zones up to 60%. Lot coverage includes all structures (buildings, garages, carports, covered patios) measured at their foundation footprint. ADUs up to 800 sq ft are exempt from lot coverage calculations per California Government Code §65852.2, meaning they can be built even on lots at maximum coverage. Uncovered decks, walkways, and swimming pools typically do not count toward lot coverage. Lot coverage variances require demonstrated hardship.
Exceeding lot coverage limits without approval may result in permit denial for new construction or required removal of non-compliant structures.
