Process
How the permit process works
Sequential — each step gates the next.
-
Confirm whether your deck is exempt or permitted Use Austin's residential permit guidance to determine whether the deck is attached, over 30 inches above grade, or over 200 square feet. If any of those conditions apply, plan on filing a permit.
-
Prepare plans and supporting documents Assemble a site plan, construction drawings, and structural details showing footings, posts, beams, joist spacing, and guardrail/stair details where applicable.
-
Submit through Austin Build + Connect Create or sign in to your AB+C account, upload the plans, and submit the residential building permit application.
-
Respond to plan review comments Austin Development Services reviews the submission against the adopted residential code and local amendments. If reviewers request revisions, update the drawings and resubmit.
-
Receive permit and pay any remaining fees Once approved, pay any remaining charges and keep the permit available on site before starting work.
-
Schedule inspections during construction Request the required inspections in AB+C as the project progresses. For a typical deck, expect footing/foundation, framing, and final inspections.
-
Pass final inspection and close out the permit After final approval, the completed deck is recorded as permitted work, which helps with insurance and future home sale diligence.

FAQ
Common Austin deck permit questions
Do I need a permit to build a deck in Austin, TX?
Usually yes if the deck is attached, higher than 30 inches above grade, or larger than 200 square feet. A small freestanding deck at or below 30 inches and 200 square feet or less may be exempt, but Austin zoning and HOA rules can still apply.
How much does an Austin deck permit cost?
Austin deck permit fees vary by project valuation. A practical estimate is $200–$650 in base city fees, covering the building permit and plan review. Actual fees depend on valuation, scope, and whether the project triggers additional review. Verify current amounts on the official fee schedule at austintexas.gov/page/fees.
What documents are usually required?
Expect a site plan, construction drawings, structural details, and the AB+C permit application. If a contractor files for you, include the owner authorization.
How long does plan review take?
A straightforward residential deck submittal commonly takes about 15 business days for plan review, with total project timing of roughly 4 to 6 weeks when inspections are included.
Can I skip the permit for a backyard deck?
Not safely. Unpermitted work can trigger stop-work orders, corrective work, and sale or insurance headaches later. If the deck is even close to Austin's thresholds, verify the exemption with Development Services before building.
