Plumbing Permit in Houston, Texas (2026)
A simple water heater replacement can get you a stop-work order and daily fines if you start without the proper Plumbing Permit from the City of Houston’s Department of Public Works & Engineering (PWE). This permit, often called a PWE plumbing authorization, is mandatory for any plumbing work that isn’t a simple repair. Most applicants complete this in under 15 minutes with ApronPrep, which auto-fills 12 of 14 fields.

Why You Need a Plumbing Permit
A Plumbing Permit is a mandatory local approval for any significant plumbing installation or alteration in Houston, required by the City of Houston Construction Code, which adopts the International Plumbing Code with local amendments, and Title 14 of the City's Code of Ordinances. The permit process, managed by the Houston Public Works Department's Building Code Enforcement Division, ensures all work meets state-mandated standards from the Texas Accessibility Standards and the Texas State Board of Plumbing Examiners rules. This legal framework is designed to prevent health hazards, ensure water safety, and protect the structural integrity of your building and the municipal water supply system.
Without this permit, your restaurant project faces immediate and costly practical consequences. Based on ApronPrep's analysis of enforcement actions in Harris County, common penalties include:
- Stop-Work Orders issued by city inspectors, halting all construction and renovation activities on-site.
- Significant fines levied per violation, with amounts escalating the longer non-compliant work remains.
- Denial of your final Certificate of Occupancy, legally preventing you from opening your restaurant to the public.
- Required demolition of completed plumbing work that inspectors cannot verify, leading to 100% loss on that labor and materials.
Legal code: State building code (locally administered), local building ordinances, state accessibility code
Recent update: As of 2026, Houston Public Works has fully implemented its digital permitting portal for all trade permits, including plumbing, requiring applications to be submitted electronically unless a waiver for paper filing is granted.
Who Needs a Plumbing Permit?
| Type | Required | Notes |
|---|---|---|
| Restaurant (Full-Service) | Required | Required — Installation of commercial-grade fixtures (e.g., three-compartment sinks, grease interceptors) triggers Houston Plumbing Code § P-101.2. |
| Bar / Nightclub | Required | Required — A commercial bar sink installation, ice machine supply lines, or drainage modifications fall under permitted work per Houston Building Code § 106.1. |
| Food Truck | Not Required | Typically exempt for plumbing on the vehicle; however, any permanent connection to a city water/sewer line (a ‘shore line’ at a commissary or fixed location) does require a permit per Houston Code § P-105.2. |
| Coffee Shop / Café | Required | Required — Installation of espresso machine water lines, prep sinks, or dishwasher connections qualifies as new plumbing work, requiring a permit under Houston Code § P-105.1. |

12 of 14 auto-filledProperty Address
textEnter the full street address of the restaurant or business where the plumbing work will be performed, matching the legal address on file with the City of Houston and Harris County.
COMMON MISTAKE: Listing a P.O. Box or a nearby cross-street instead of the exact physical address, which causes the permit to be flagged for incorrect location.
Permit Type
textSpecify the exact category of plumbing permit required, such as 'New Construction,' 'Alteration/Repair,' 'Water Heater Replacement,' or 'Fixture Installation' as defined by Houston Public Works.
COMMON MISTAKE: Using generic terms like 'plumbing work' or selecting the wrong permit type (e.g., 'Alteration' for a new grease interceptor install), which triggers a review for incorrect scope.
Description of Plumbing Work
textProvide a clear, detailed description of all plumbing work, including fixture counts (e.g., 'Install 3 new sink basins, 2 toilets, and associated DWV lines'), materials, and connection points.
COMMON MISTAKE: Submitting vague descriptions like 'fix plumbing' or omitting key details like fixture quantities, which results in a 'scope clarification' hold from plan reviewers.
Using Licensed Contractor
checkboxCheck this box if a licensed plumbing contractor will perform the work; if you are the property owner performing your own work (owner-builder), leave it unchecked and you must sign an affidavit.
COMMON MISTAKE: Incorrectly checking the box when acting as an owner-builder, which then requires submission of invalid contractor documents and causes immediate rejection.
Contractor License Number
textIf using a contractor, enter their current Texas State Board of Plumbing Examiners (TSBPE) Master Plumber License number, which is required for all commercial plumbing work in Houston.
COMMON MISTAKE: Entering an expired license, a Journeyman license number instead of a Master license, or a license from another state, which fails the TSBPE database verification.
Contractor Registration Number
textEnter the contractor's City of Houston Local Business Registration number, which is separate from the state license and is required to legally pull permits within city limits.
COMMON MISTAKE: Leaving this field blank or entering an inactive/out-of-city registration, resulting in a 'non-compliant contractor' hold until proof of current Houston registration is provided.
Contractor License Certificate
textConfirm you have a copy of the contractor's active TSBPE license certificate; you must attach this PDF to the application or the permit will not be processed.
COMMON MISTAKE: Attaching an expired license certificate or a screenshot instead of the official TSBPE-issued PDF, which reviewers reject for non-verifiable documentation.
Contractor Registration Certificate
textConfirm you have a copy of the contractor's current City of Houston Local Business Registration certificate, which must be submitted with the application packet.
COMMON MISTAKE: Submitting an expired city registration or a state license as proof of city registration, causing a mismatch with the registration number field and triggering a rejection.
Plumbing Plans and Specifications
textConfirm that detailed plumbing plans, drawn to scale by a Texas-registered professional engineer or designer, are ready for submission, as they are mandatory for all but minor repair permits.
COMMON MISTAKE: Assuming simple repairs don't need plans or submitting hand-drawn sketches without engineer seals, which leads to an automatic 'plan deficiency' rejection.
Application Form Completed
checkboxCheck this box to affirm that all sections of the City of Houston Plumbing Permit Application (Form PWE-510P) have been filled out completely and accurately before submission.
COMMON MISTAKE: Checking this box with missing or contradictory information elsewhere on the form, which constitutes a false certification and can lead to application denial and fines.

Top 5 Plumbing Permit Mistakes
1. Incorrectly Sizing and Listing Water Fixtures
Using generic fixture counts (e.g., '3 sinks') instead of specifying the exact fixture type (e.g., 'lavatory, 1.2 gpm'), location, and proposed flow rate. Houston Public Works reviews for compliance with the 2018 International Plumbing Code's water conservation standards. This omission triggers a 'Plan Correction' notice, adding 2-3 weeks for a resubmission cycle. ApronPrep auto-fills this section using your uploaded floor plan to generate a precise fixture schedule.
2. Omitting Contractor/Sub-Contractor License Numbers
Leaving the 'Licensed Plumber' or 'Master Plumber' information blank or entering an expired license number. Houston requires the responsible Master Plumber's Texas State Board of Plumbing Examiners (TSBPE) license number to be active and in good standing. Applications without a valid, verifiable license are rejected outright, as the city cannot issue a permit to an unlicensed entity. Always verify your plumber's current TSBPE license status before listing it.
3. Incomplete or Missing Site Plan/Floor Plan Details
Submitting a site plan that lacks the required scale, dimensions, or clear routing from the main sewer line or water meter to the proposed work area. For interior work, failing to show the location of all existing plumbing walls, vents, and stacks relative to new fixtures is a common error. Incomplete plans result in a 'Plans Held for Corrections' status, delaying review by the plans examiner until corrected documents are uploaded, typically adding 10+ business days to your timeline.

Visit the Houston Permitting Center located in downtown Houston or access the online portal
Begin by creating an account on the City of Houston's iPermits portal (http://www.houstontx.gov/permits) or prepare to visit the Houston Permitting Center at 1002 Washington Ave. You need your business's legal name, address, and the Contractor's license number of the licensed plumber performing the work before starting. Most initial planning takes 30–60 minutes.
Complete the plumbing permit application form
Enter all required data into the official City of Houston plumbing permit application. You'll need precise details: the licensed plumber's state license number, the exact property address (including suite number), the valuation of the plumbing work, and a detailed scope of work description. Applications listing incomplete contractor details are the #1 cause of same-day rejection. Completion typically takes 20-30 minutes if you have all information ready.
Submit application through online system or in-person at the Permitting Center
Upload your completed application and any required supplemental documents (like detailed plumbing diagrams for complex jobs) through the iPermits portal or submit paper copies at the Permitting Center public counter. For online submissions, you must upload all documents as a single PDF under 10MB. Missing supplemental plans for non-residential projects is a common cause of processing delays. Submission takes 1 day.

See All RequirementsProcessing time varies significantly and is not a fixed timeline, according to the Houston Public Works Department. The review duration depends entirely on the project's complexity and the current volume of applications in the permit queue. For a definitive estimate on your specific project, you must contact the authority directly—applicants should plan for this uncertainty to avoid construction delays, especially when coordinating with other permits like a Building Permit.
The government filing fee for this permit is listed as $0–$0. However, this does not mean the permit is free—the cost is typically calculated based on the scope and valuation of your specific plumbing work, as determined by Houston Public Works during plan review. You must contact the authority for a fee quote based on your project details; this upfront cost variability is similar to the process for an Electrical Permit. Not legal advice — verify fees with Houston Public Works.
No, plumbing permits are not transferable between locations, per standard Houston Public Works policy. A permit is issued for a specific property address and scope of work; any change in location requires submitting a new application. This site-specific rule mirrors other local permits, such as a Certificate of Occupancy, which are also tied to a particular building.
Plumbing permits themselves are not renewable—they are single-use authorizations for a defined project. However, if work is not started or completed within the timeframe stated on the issued permit, it will expire, and you must apply for a new one. Separate from the permit, ongoing compliance is required for related systems, such as maintaining an active Backflow Prevention Device Certification, which does require periodic renewal.
A city inspector from Houston Public Works will visit the job site to verify the installed work matches the approved plans and complies with the International Plumbing Code (IPC), as adopted by the City of Houston. They will check for proper materials, venting, drainage, fixture installation, and connections. You must have the approved permit card and plans on-site; failing inspection can result in rework orders and significant project delays.
