Round Rock permits and contractor registration

Round Rock residential permits are applied for through the city's Permit Portal at permits.roundrocktexas.gov. The city runs a strict one-permit system: the general contractor and each subcontractor must accept their assignment in the portal before the permit is issued. So the plumber, electrician and HVAC company on a remodel should all appear on one permit record. Ask for the permit number and look it up yourself.

The Building Inspection Department also keeps a contractor registration sheet for general, plumbing, mechanical, electrical and irrigator contractors, signed by the license holder. A state license and a city registration are separate checks, so ask the company whether it is registered with Round Rock before the job is scheduled.

Before tree removal or work near a creek, ask the city which tree-size and floodplain rules apply to your lot.

Round Rock power, water and watering days

Oncor delivers electricity in Round Rock, and residents choose the retail provider that bills them through Power to Choose. Atmos Energy provides gas. If you are moving in, you pick an electricity plan yourself.

The City of Round Rock provides water, wastewater, stormwater drainage, and garbage and recycling. Its water service area also includes several municipal utility districts outside city limits, so a neighbor a mile away may be a city water customer without living in the city.

Round Rock was in no drought stage when checked on October 22, 2026. Its Year-Round Water Use Standards allow outdoor watering only before 10 a.m. or after 7 p.m., on days set by the last digit of your address: 0 waters Monday and Thursday, 1 waters Wednesday and Saturday, and 4 or 8 waters Sunday and Thursday.

Brush, mosquitoes and property taxes in Round Rock

Residents inside city limits can request curbside brush pickup by 4 p.m. Tuesday for that week, run by Round Rock Refuse, or drop off up to 2 cubic yards of brush free at the Brush Recycling Center, 310 Deepwood Drive. Ask a tree crew whether its price includes hauling, since the city route may cover small loads.

The Williamson County and Cities Health District, based at 355 Texas Ave. in Round Rock, runs mosquito surveillance and coordinates treatment with cities, but does not treat private property. A backyard problem is yours or a licensed pest company's to handle.
