Decks over 30 inches above grade require a building permit in Bexar County. Ground-level patios at grade generally do not require a permit. Covered patios and pergolas attached to the house may require permits depending on size.
Under the 2021 International Residential Code adopted by Bexar County, decks more than 30 inches above adjacent grade require a building permit. Ground-level patios (concrete, pavers) at grade do not require a permit. Attached decks must meet structural requirements for ledger board connections and footings. All decks must meet zoning setbacks. Guardrails at least 36 inches high are required where the deck is more than 30 inches above grade. Covered patios and pergolas attached to the dwelling typically require permits. In San Antonio, permits are obtained through the Development Services Department. Plan review typically takes 1-2 weeks for residential decks.
Unpermitted decks may result in stop-work orders, fines up to $2,000 per day, and requirement for retroactive permits. Unsafe decks may be ordered removed.
