Decks over 30 inches above grade require a building permit in San Bernardino County. Ground-level patios and decks less than 200 square feet that are under 30 inches above grade and not attached to a dwelling generally do not require a permit.
San Bernardino County follows California Building Code exemptions for decks and patios. Decks not exceeding 200 square feet, not more than 30 inches above adjacent grade, not attached to a dwelling, and not serving a required exit door are exempt from building permits. Decks over 30 inches above grade require a building permit and must comply with structural requirements, including guardrails at least 42 inches high. Concrete patios at grade generally do not require a permit. Covered patios and pergolas may require permits depending on size and attachment to the house. All decks and patios must meet zoning setback requirements. Permit applications require construction drawings showing structural details, footings, and connections.
Building a deck without a required permit may result in stop-work orders, administrative citations, and the requirement to obtain a retroactive permit. Unsafe decks may be ordered removed.
