If you are planning a whole-house repipe in Houston, one of the first questions you will probably ask is: do I need a permit? The short answer is yes. The City of Houston requires a plumbing permit for any work that involves replacing, rerouting, or installing new water supply lines throughout a home. Understanding the permit process before your project starts can save you from delays, failed inspections, and potential legal headaches down the road.

This guide walks you through everything Houston homeowners need to know about repiping permits, including who pulls them, what they cost, and why skipping the permit is never worth the risk.

Does Repiping Require a Permit in Houston?

Yes. Under the City of Houston plumbing code, any project that modifies or replaces the water distribution system inside a residential structure requires a plumbing permit issued by the City. A whole-house repipe, which involves removing old galvanized, polybutylene, or deteriorating copper lines and replacing them with new PEX-A or copper piping, falls squarely into this category.

This applies whether you live inside Houston city limits, in an ETJ (extraterritorial jurisdiction) area, or in a surrounding municipality like Sugar Land, Katy, or Pearland, each of which has its own permitting authority. If your property falls in unincorporated Harris County, county-level permits may apply instead.

Minor repairs, such as fixing a single leaking joint or replacing a faucet, typically do not require a permit. But once you are replacing supply lines through walls, ceilings, or a slab foundation, a permit is required.

Who Is Responsible for Pulling the Permit?

In Houston, only a licensed master plumber or a licensed plumbing company can pull a plumbing permit. Homeowners cannot pull their own plumbing permits in the City of Houston the way they can in some other Texas cities.

This means your repiping contractor should handle the entire permit process on your behalf. At We Do Repipes, we pull all necessary permits before any work begins. If a contractor tells you permits are not needed, or asks you to pull the permit yourself, that is a major red flag. It often signals unlicensed work, which creates serious problems if something goes wrong or when you try to sell the home.

What Does the Permit Process Look Like?

The typical permitting process for a residential repipe in Houston follows these steps:

Step 1: Application. The licensed plumbing company submits a permit application to the City of Houston Department of Public Works and Engineering. This includes details about the scope of work, the property address, and the contractor license information.

Step 2: Permit Issuance. For straightforward residential repipes, permits are often issued within one to two business days. Some contractors use the city online portal for faster processing.

Step 3: Work Begins. Once the permit is issued, the repiping work can begin. The permit number is associated with the property and must be available on-site during the project.

Step 4: Inspection. After the repipe is complete, the city sends a plumbing inspector to verify the work meets code. The inspector checks pipe materials, connections, support brackets, water pressure, and overall workmanship. If everything passes, the permit is closed out.

Step 5: Final Approval. A passed inspection means the work is officially approved by the city. This record stays on file and can be pulled up during a future home sale or insurance claim.

How Much Does a Repiping Permit Cost in Houston?

Permit fees for residential plumbing work in Houston are relatively affordable. For a standard whole-house repipe, the permit fee is typically between $50 and $150, depending on the scope of work and the number of fixtures involved.

At We Do Repipes, the cost of the permit is included in your project estimate. You should never pay a separate surprise fee for permitting. If a contractor does not mention permits at all in their quote, ask about it directly. It is a basic part of any legitimate repiping job.

What Happens If You Repipe Without a Permit?

Skipping the permit might seem like a way to save time or money, but it creates significant risks for homeowners:

Failed home sale. When you sell your home, the buyer title company and inspector will often check for open or missing permits. Unpermitted plumbing work can delay or kill a sale, or force you to pay for a retroactive permit and re-inspection before closing.

Insurance denial. If a pipe fails and causes water damage, your homeowners insurance company may deny the claim if the plumbing work was done without a permit. Insurers view unpermitted work as a material risk factor.

Code violations and fines. The City of Houston can issue fines for unpermitted work. If the work is discovered during a future renovation, addition, or complaint, you may be required to open walls, expose the piping, and have it inspected after the fact, which is far more expensive than doing it right the first time.

Safety concerns. The inspection process exists to catch mistakes. Without it, there is no independent verification that the work was done correctly. Improperly installed pipes can leak inside walls, cause mold, or fail under pressure.

Do Surrounding Cities Require Permits Too?

Yes. Virtually every incorporated city in the Greater Houston area requires a plumbing permit for repiping work. Here is a quick overview:

Sugar Land: Permits issued through the city Building Services Department. Inspections required.

Katy: Homes inside Katy city limits follow Katy permitting. Homes in the Katy area but within Harris or Fort Bend County follow county or Houston ETJ rules.

Pearland: Permits through the Pearland Permits and Inspections Division. Standard residential plumbing permit required.

The Woodlands: Falls under Montgomery County or the jurisdiction of The Woodlands Township depending on exact location.

League City, Friendswood, Pasadena, Baytown: Each has its own permitting office and inspection process. Your contractor should know which jurisdiction your property falls under and pull the correct permit.

Questions to Ask Your Repiping Contractor About Permits

Before hiring a repiping company, ask these questions to make sure the permit process is handled properly:

Are you licensed to pull plumbing permits in my city? Make sure the contractor holds a valid master plumber license in the jurisdiction where your home is located.

Is the permit fee included in your estimate? Reputable companies include permitting in the total project cost.

Will the work be inspected by the city? A yes answer means the contractor is doing things the right way. If they dodge this question, move on.

Can you provide the permit number before work starts? You should be able to look up the permit on the city website to confirm it is active and associated with your address.
