Do I need a permit for solar panel installation in Travis County (Unincorporated)?
Yes. In Texas, solar panel installation generally requires a permit, and Travis County (Unincorporated) is no exception.
Texas cities require both a building and an electrical permit for a rooftop solar system, and utilities such as Austin Energy require a separate interconnection approval in addition to the city permit. Ground-mount and building-integrated (solar-shingle) systems face additional plan-review and engineering requirements beyond a standard roof-mount array. Confirm scope with the local building department and your utility. In Travis County, permits outside the cities are handled by the Travis County TNR Development Services, reachable on 512-854-4215 at https://www.traviscountytx.gov/tnr/development-services/permitting-center. Its online permit portal is https://www.mypermitnow.org. This office covers the unincorporated parts of Travis County. Texas counties differ widely in how much residential work they permit, and many do not issue residential building permits at all, so confirm what your specific project needs. If your address sits inside a city, that city issues the permit instead. Solar involves a building permit for the attachment and a separate electrical permit, plus a utility interconnection that runs outside the permit process.
