Short answer
Yes. The City of Houston requires a plumbing permit to replace or install a water heater, and only a master plumber registered with the City of Houston may obtain it.

What does Houston require to replace a water heater?
The Houston Permitting Center publishes one permit for this job, HPWCODE1101[1]. Here is what it says, as read on October 14, 2026:
| Item | City of Houston rule[1] |
|---|---|
| Permit needed? | Yes, to replace or install a water heater |
| Who may obtain it | A master plumber registered with the City of Houston |
| Plan review | Not required for a single-family residence |
| Inspection | Required |
| Heater fee | $34.24 for the first three heaters, $11.41 per heater after that |
| Admin fee | $33.56 |
| Minimum permit fee | $97.56 in the fee line; $91.05 in the conditions section |
| Valid for | 180 days |
| Processing time | 1 business day |
| Code basis | 2021 Uniform Plumbing Code and 2021 International Residential Code, each with Houston amendments |
The page lists two different minimum fees[1]. We report both rather than guess which is current. The plumber pulling the permit will see the charged amount at checkout, so ask for the permit receipt with your invoice.
Can a Houston homeowner pull the permit themselves?
In practice, no. Two rules point in different directions, and both are real.
State law. Texas Occupations Code 1301.051 says a property owner does not need a plumbing license to do plumbing in their own homestead[2]. That is an exemption from the state license, not from city permits.
City rule. Houston's permit page says the water heater permit "must be obtained by a master plumber registered with the City of Houston"[1]. A homeowner without that registration cannot be the permit holder.
So a permitted water heater replacement inside Houston city limits runs through a city-registered master plumber. Texas plumbing licenses come from the Texas State Board of Plumbing Examiners (TSBPE)[4]. Under the board's rules, a company may not advertise or contract for plumbing work unless it has secured at least one Responsible Master Plumber holding a current Master Plumber License[3]. The master plumber who pulls your permit is the person accountable for the work.
What do nearby cities require?
Each city in the metro sets its own permit process. Houston's rule stops at the city limits.
| City | What the city publishes | Source |
|---|---|---|
| Houston | Permit required; city-registered master plumber must obtain it; $34.24 heater fee plus $33.56 admin fee; inspection required | [1] |
| Pasadena | Residential gas or electric water heater is a $15.00 line item on the plumbing permit; minimum permit fee $50 including the application fee; the application requires a master plumber's signature | [5] |
| Sugar Land | Water heater replacement is an Express Permit: no plan review, issued right after online application and payment, inspection can be scheduled right away | [6] |
| League City | Plumbing permit base fee $75 plus $7 per fixture; the schedule does not name water heaters, so confirm with the Building Department | [7] |
| Pearland | A construction permit is required for work on plumbing systems tied to a structure; water heaters are not named on the page | [8] |
We did not find a published water heater permit rule for Conroe. If your city is not listed, call its building or permitting department and ask two questions: is a permit required to replace a water heater, and who may pull it.
What does the permit cost the homeowner?
The city fees are a small part of the job. For one heater in Houston, the published heater fee plus the admin fee comes to $67.80, but the page also lists a minimum permit fee of $91.05 or $97.56[1]. Plumbers usually fold the permit into the quote. When you compare quotes, ask whether the permit is included, because a quote that leaves it out is not comparable to one that includes it. For the full installed price, see our water heater replacement cost page.
Why the permit is worth having
The inspection is the only point where a third party checks the install against the city code. Houston's code basis is the 2021 Uniform Plumbing Code and 2021 International Residential Code with local amendments[1]. Items such as the relief valve discharge line, venting on gas units and the expansion tank are where installs tend to go wrong. A permit record also helps when you sell the house or file an insurance claim.
When to call a pro
- Any water heater replacement inside Houston city limits: the permit must come from a city-registered master plumber.
- A switch from tank to tankless, or from gas to electric or heat pump: gas sizing, venting and new circuits are trade work.
- A relief valve that drips or discharges: see our relief valve guide and have a licensed plumber check it.
- If you smell gas, leave the house now, do not use switches or phones inside, and call 911 or your gas utility from outside. In Houston the natural gas utility is CenterPoint Energy[9].
More questions
Does a tankless or heat pump water heater need the same Houston permit?
Houston's permit page covers installing or replacing a water heater and does not split it by type. A gas tankless unit may also involve gas piping and venting, and a heat pump unit may need a new circuit, which can bring separate trade permits. Ask the plumber which permits the job needs.
How long is a Houston water heater permit good for?
The City lists the permit as valid for 180 days, with processing of about 1 business day.
I live in Kingwood or Clear Lake. Do Houston rules apply?
If your address is inside the City of Houston limits, yes. If it is in a separate city, such as Pasadena or League City, that city's building department sets the rule. Check the city name on your property tax statement.
