Deck Construction Permits in San Antonio
Local Rule
City of San Antonio Development Services Department (DSD)
San Antonio's Development Services Department confirms a real tiered permit system based on scope: a smaller one-story deck uses a Residential Improvements Permit, while any deck over 1,000 square feet or two stories needs the full Residential Building Permit. The narrow exemption applies only to a deck 200 square feet or less, no more than 30 inches above grade, not attached to the home, and not supporting a hot tub; missing any condition, including that last hot tub carve-out, triggers a permit. A property in a floodplain needs additional review from Public Works, and a historic-designated property needs approval from the Office of Historic Preservation before the deck permit can be issued.

How This Compares to Bexar County
San Antonio's own rule is shown above (Depends on project scope). Here is the separate rule that applies at the county level, for context:
City of San Antonio Development Services (BuildSA)
The City of San Antonio requires a permit for most residential decks and uses a distinctive two-tier system based on size. A smaller one-story deck is permitted through the simpler Residential Improvements Permit in the BuildSA portal (approval often in one to two days), while a deck over 1,000 square feet OR a two-story deck must use the full Residential Building Permit with complete construction documents (Information Bulletin 151). The general trigger is a deck more than 200 square feet, more than 30 inches above grade, or attached to the home; construction documents must show footings, decking, stairs, handrails, guards, and joist spans for code compliance under the adopted IRC. Two local wrinkles: a property in a floodplain needs additional review from Public Works, and a historic home requires approval from the Office of Historic Preservation before permitting. Owner-builders must certify they will live in the home for more than 12 months, if selling in the short term, a license
