Deck Construction Permits in Austin
Local Rule
Austin Development Services Department (DSD)
The city's own Work Exempt from Building Permits page states the exemption directly, with a genuinely more detailed fifth condition than most cities publish: a deck no more than 200 square feet, no more than 30 inches above grade at any point, not attached to a dwelling or townhouse, not providing egress from the dwelling, and not located within a flood hazard area needs no permit; all five conditions must hold at once. A real local detail tied to Austin's expansive clay soil: footings need to go only 18 inches deep in the city itself, deepening to 24 inches for areas north of Austin. Applications go through the Austin Build + Connect (AB+C) online portal, and DSD can be reached directly at (512) 978-4000.

Travis County Transportation and Natural Resources
Deck permits in unincorporated Travis County (much of Spicewood and the Hill Country) are administered by Transportation and Natural Resources, a fully separate department from the City of Austin's Development Services Department, with its own submission portal, fee schedule, review timeline, and inspection protocol. Incorporated municipalities within the county (Lakeway, Bee Cave, West Lake Hills) also run entirely independent building departments.
