What requires a building permit in Travis County?

If you're doing work in Travis County, most new construction, structural changes, or system installations will require a permit. Travis County permits make sure your project is safe, zoning compliant, and environmentally protected (especially in water quality zones).

  • Additions, remodels, or renovations to existing residences
  • Accessory buildings / non-habitable structures (e.g. shed, gazebo) on residential property
  • Fences, retaining walls, driveways, pools/spas, septic/on-site sewage facilities (OSSF), and other site-improvement work
  • Work in county right-of-way (ROW), or utility / sewage / drainage installations on unincorporated land

  • Subdivision of land, grading, clearing, excavation, filling, paving, or other land-use changes
  • Projects in or affecting flood-prone areas / drainage / stormwater / environmental impact
