Because Austin is still in Texas, there is no new driver license to get and no out-of-state vehicle inspection to schedule. You do need to update your address. Texas asks drivers to change the address on their license within 30 days of moving, which you can do online through the Texas Department of Public Safety, and your vehicle registration should be updated with the county tax office as well. For utilities, the City of Austin runs Austin Energy and Austin Water, so most addresses inside the city set up electric and water service through the city’s utility customer service.
