Small, low, freestanding decks may be exempt. Permit required if: more than 200 sq ft (unverified — some sources say 300 sq ft), more than 30 inches above grade, attached to dwelling, or serves a required exit door.
If your deck does NOT meet all exemption criteria, you must obtain a permit before construction. Building without a required permit can result in fines, stop-work orders, and required demolition.
Review the exemption criteria above. If your deck exceeds any threshold, a permit is required.
You'll need a site plan, deck dimensions, framing details, and footing specifications. Check San Antonio's specific documentation requirements.
Apply through BuildSA . Pay the permit fee at submission.
Once approved, post your permit visibly and schedule required inspections (typically footing, framing, and final).
