Process
How the permit process works
- Determine whether your deck requires a permit Check whether the deck is attached to the house, or whether it will exceed 30 inches above grade at any point or 200 square feet as a freestanding structure. If any condition applies, a building permit is required through the San Antonio Development Services Department (DSD).
- Prepare plans and supporting documents Draw up a site plan and construction drawings showing footings, posts, beam sizes, joist spacing, decking layout, guardrail details, and stair layout if applicable. San Antonio plan reviewers reference the 2021 IRC with local amendments, so standard IRC-compliant structural details are accepted.
- Submit through the DSD online permit portal Create or log in to an account at sanantonio.gov/DSD, select the appropriate residential building permit type, upload your documents, and submit. In-person service is also available at the DSD offices at 1901 S. Alamo St., San Antonio, TX 78204.
- Respond to plan review comments DSD reviewers evaluate the submittal against the 2021 IRC with local amendments and the San Antonio Unified Development Code. If corrections are requested, update the drawings and resubmit through the portal.
- Receive approval and pay remaining fees Once the permit is approved and all fees are paid in full, save or print the issued permit. Keep the permit card or approval document accessible at the job site during all phases of construction.
- Schedule required inspections Request inspections through the DSD portal or by contacting Development Services as construction progresses. A typical deck requires a footing or foundation inspection before pouring concrete, a framing inspection before covering structural members, and a final inspection.
- Pass final inspection and close out the permit After the inspector signs off on the final inspection, the permit is closed and the completed deck becomes part of the official city record. This protects you during home sales, insurance claims, and future permitting.
Code basis
What Austin reviews against
2021 International Residential Code (IRC) as adopted by the City of San Antonio with local amendments, administered by the San Antonio Development Services Department (DSD).
If you skip the permit
What can go wrong
- San Antonio Development Services can issue a stop-work order if unpermitted construction is discovered.
- The city may require the deck to be structurally opened for inspection or removed entirely at the owner's expense.
- Fines and daily penalties can accrue under city code until the violation is resolved.
- Homeowner's insurance may deny claims for damage caused by or related to unpermitted structures.
- Unpermitted work flagged during a home sale can delay or kill a transaction, and retroactive permitting is more expensive and disruptive than doing it upfront.
- Unpermitted decks may create liability exposure if a guest is injured on a structure not inspected for code compliance.

FAQ
Common Austin deck permit questions
Do I need a permit to build a deck in San Antonio, TX?
Usually yes. A building permit is required for any deck attached to the house and for any freestanding deck that is taller than 30 inches above grade at any point or larger than 200 square feet. A small, low freestanding deck at or below 30 inches and 200 square feet or less may not require a permit, but San Antonio zoning setbacks and HOA rules still apply.
How much does a San Antonio deck permit cost?
San Antonio permit fees are based on the declared construction valuation. For a typical residential deck, expect roughly $150–$450 in combined building permit and plan review fees. Actual amounts depend on project size, scope, and valuation. Confirm the current fee schedule at sanantonio.gov/DSD before applying.
Where do I apply for a deck permit in San Antonio?
Submit your application through the San Antonio DSD online permit portal at sanantonio.gov/DSD/Permits. In-person service is available at the Development Services Department offices at 1901 S. Alamo St., San Antonio, TX 78204.
What documents are required for a San Antonio deck permit?
At minimum, submit a scaled site plan, construction drawings with dimensions and framing layout, footing and structural details, and a completed permit application through the DSD portal. For an attached deck, include a ledger attachment and flashing detail. If a contractor applies for you, include appropriate authorization and contractor license documentation.
How long does plan review take in San Antonio?
Residential deck submittals typically take 10–15 business days for plan review. Total project time including inspections is generally 4–6 weeks, but resubmittals for corrections can extend that timeline.
What building code does San Antonio use for decks?
San Antonio adopted the 2021 International Residential Code (IRC) with local amendments, administered by the Development Services Department. Deck design and framing should comply with IRC Section R507 (Exterior Decks) and the applicable structural provisions in Chapters 5–6.
Can I build a small deck without a permit in San Antonio?
Possibly, if the deck is freestanding (not attached to the house), no more than 30 inches above grade at any point, and 200 square feet or less in area. However, San Antonio zoning setbacks and the Unified Development Code still apply, and HOA covenants may impose additional restrictions. If in doubt, contact San Antonio DSD before you build.
What inspections are required for a San Antonio deck permit?
A standard residential deck permit typically requires a footing or foundation inspection before pouring concrete, a framing inspection before covering structural members, and a final inspection upon completion. Your permit documentation will list the specific inspections required for your project.
