Driveway
A driveway onto a Travis County road may need a permit
Out past the city street systems, a driveway isn't just your business. Where it meets a county-maintained road, it's a road-access question the county wants a say in. Connecting a driveway to a maintained Travis County road takes a county driveway permit, and that requirement shows up on both the single-family and the commercial development tracks.
For a house on a few acres or a business site, that means the legal entrance onto a county road can hinge on getting the curb cut, the culvert, and the drainage right. Promise a buyer access in a land sale before the county has signed off, and you may be promising something you can't yet deliver.
Square it with Travis County Transportation and Natural Resources at (512) 854-4215 before anyone breaks pavement, since the access point and the right-of-way work usually need their review first.
