Window replacement costs in Austin

Austin publishes a list of the jobs that don't need a building permit, and it's specific. Replacing a door with one of the same size and operation is on it. Windows aren't, so a window swap isn't one of the exemptions the City spells out.

The energy code is the City's own, too, and newer than the state's. Austin has enforced the 2024 International Energy Conservation Code, with local amendments, since July 10, 2025. Texas's statewide rule for houses is still the energy chapter of the 2015 International Residential Code, in force since September 1, 2016. Travis County is in climate zone 2, labeled hot-humid in the federal climate-zone guide.

Older neighborhoods add another layer. Austin has eight local historic districts. On a contributing property in one of them, exterior changes need approval from the Historic Preservation Office or the Historic Landmark Commission, apart from routine maintenance and in-kind repairs, and the work has to follow that district's design standards. If you rehabilitate a contributing house, the City offers a property tax abatement on the value the work adds, as long as the work meets those standards.
