Travis County primarily handles development permits for unincorporated areas, focusing on floodplains, septic systems, and driveway access. Incorporated cities like Austin, Pflugerville, and Cedar Park maintain exclusive jurisdiction over building and zoning permits within their respective city limits. Development in unincorporated areas is subject to additional review for environmental regulations, including the Balcones Canyonlands Conservation Plan.
How this fits with the state
The state authority here is Texas Department of Licensing and Regulation; Texas State Board of Plumbing Examiners. The county file does not replace that — it adds the permit office, local overlays, and the actual filing path.
