Deck permit checklist — San Diego County, California

Do you need a permit?
San Diego County requires a permit for a deck.
Per PDS 110, decks, walks and driveways are exempt from a building permit when they are not more than 30 inches above adjacent grade. Above that height, or where the deck is attached to the dwelling structurally, serves an exit door, or carries a roof or cover, a permit is required. San Diego County does not add a square-footage cap to this exemption the way Riverside County does, so height above grade is the whole test. A related exemption allows a patio cover up to 300 square feet of projected roof area, which frequently comes up on the same project. WUI construction requirements and Fire District approval apply to attached decks in high fire hazard unincorporated areas even where the height exemption would otherwise apply.
