How Round Rock plumbing permits name the plumber
Texas cities of more than 5,000 people must regulate plumbing by ordinance, water heaters included, and require a permit. The exceptions are small jobs such as fixing a leak or swapping a faucet, ballcock, garbage disposal or toilet. A water heater replacement, a slab leak reroute or new bathroom lines fall on the permit side.
Round Rock applies for residential permits through permits.roundrocktexas.gov and runs what it calls a strict one-permit system. On a remodel, the general contractor holds the permit and each subcontractor, the plumber included, has to accept its assignment in the portal before the permit issues. If a contractor says the plumbing is "covered under the main permit", look up the record and check that a plumbing company has accepted it.
Before any Texas city issues a plumbing permit, it must check with the Texas State Board of Plumbing Examiners (TSBPE) that the Responsible Master Plumber has a certificate of insurance on file. Installed work then has to be inspected by a licensed plumbing inspector. Keep the final payment until that inspection passes.
Round Rock plumbing contractor registration
Separately from the permit, the Building Inspection Department keeps a registration sheet for plumbing contractors, signed by the license holder.
Checking a Round Rock plumber's license
Every Texas company that advertises plumbing must secure the services of a Responsible Master Plumber (RMP). That person pulls permits, requests inspections, makes sure the crew is licensed or registered, and makes sure the trucks show the company name and the RMP's license number.
- The paperwork: each written proposal, invoice or contract must show the RMP's name and license number plus TSBPE's name, mailing address and phone number, and you must get an invoice when the job is done.
- The lookup: TSBPE's Public License Search finds a plumber by name, license number, city or county.
- The insurance: the RMP must keep at least $300,000 of commercial general liability coverage on file with TSBPE.
- The person in your house: license and registration holders must carry the card on them while working.
TSBPE issues four licenses (Tradesman Plumber-Limited, Journeyman, Master and Plumbing Inspector), each renewed every year. A homeowner can do plumbing in their own homestead without a license, though you should check Round Rock's permit rules first; anyone you pay needs one. Complaints go to TSBPE on its General Complaint Form; the board's number is (512) 936-5200.
What a plumber costs in Round Rock
The useful yardstick is national: HomeGuide puts U.S. plumber rates at $45 to $150 an hour, with average jobs at $125 to $450 and service-call fees of $50 to $200. A burst pipe repair runs $400 to $2,000, or about $150 to $250 per linear foot of pipe.
Ask whether the service-call fee is credited to the repair, and whether the quote includes the city permit. The Texas plumbing guide covers pricing by job type in more detail.
Round Rock water lines, sprinklers and freezes
The City of Round Rock provides both water and wastewater, and its water service area also includes several municipal utility districts outside city limits. If you live in one of those districts, ask your plumber whether city or district rules apply to a sewer tap or meter-side repair.
Outdoor watering is allowed only before 10 a.m. or after 7 p.m. on your assigned days under the Year-Round Water Use Standards (no drought stage when checked in October 2026). Round Rock also registers irrigator contractors on the same sheet as plumbers, so a sprinkler repair firm should be able to show it is on file. A backflow assembly test needs a TCEQ Backflow Prevention Assembly Tester license, valid for three years.
Texas health officials confirmed 246 deaths related to the February 2021 winter storm. Have exposed attic and exterior lines checked in the fall, and book the Round Rock AC and heating tune-up the same week. City-wide hiring rules sit on the Round Rock hub, and Georgetown plumbers work under that city's MGO Connect permits.
Round Rock plumber FAQs
Does a water heater replacement in Round Rock need a permit?+
Texas law has cities of more than 5,000 people require plumbing permits, and it names water heaters specifically. Ask the plumber to pull the permit in the Round Rock Permit Portal and give you the number.
How do I know my plumber is licensed in Texas?+
Find the Responsible Master Plumber's name and license number on the quote, which state rules require, then search it on TSBPE's Public License Search.
Can I cancel a plumbing job within three days?+
Texas's three-day home-solicitation cancellation law generally does not apply to plumbing work you called for, except for breach of an express warranty or negligent installation that violates code. Read the contract before you sign.
Does the plumber have to register with Round Rock?+
Round Rock keeps a plumbing contractor registration sheet signed by the license holder. Ask the company to confirm it is on file with the Building Inspection Department.
