Why You Need a Plumbing Permit
A Plumbing Permit in San Antonio is required by state and local law to ensure all plumbing work meets minimum health and safety standards. The primary legal authority is the International Plumbing Code (IPC), as adopted by the State of Texas and amended by the City of San Antonio's Local Building Codes. Additionally, the work must comply with the Texas Accessibility Standards (TAS) for any public facilities. This permit is administered and enforced by the City of San Antonio Development Services Department (DSD). You cannot legally install, alter, or replace any water supply, drainage, or vent system without this permit on file.
Proceeding without this permit triggers immediate enforcement actions. Based on the City's enforcement protocols, the primary consequences are:
- Stop-Work Orders: The DSD will post an order on your site, halting all construction. You cannot proceed until the permit is obtained and inspections are scheduled, adding weeks to your timeline.
- Fines and Penalties Government authorities can levy fines, often calculated as a multiple of the original permit fee. Unpermitted work discovered during a final inspection can void your Certificate of Occupancy.
- Required Demolition If the work is found to be non-compliant with code, you may be forced to demolish and rebuild the plumbing at your own expense to pass inspection.
- Insurance and Sale Complications Most property insurance policies exclude coverage for damages caused by unpermitted work. Furthermore, unpermitted improvements can cause significant delays or cancellations during a property sale or refinancing.
Legal code: State building code (locally administered), local building ordinances, state accessibility code
Recent update: In 2025, San Antonio DSD integrated its plumbing permit application more fully into its online SA Permit Center portal, reducing the need for paper submittals for most residential and commercial projects.

Top 5 Plumbing Permit Mistakes
1. Using the Wrong License Number for the Master Plumber
Entering a journeyman license number or an expired license for the supervising Master Plumber is the top cause of immediate rejection. The City of San Antonio's Development Services Department requires the active, Master-level license number from the Texas State Board of Plumbing Examiners (TSBPE). If you input an invalid or incorrect number, the application is flagged and returned, adding 5–7 business days to your timeline. Always verify the Master Plumber's TSBPE license is current and matches the name on the application.
2. Incomplete or Incorrect Job Site Address
Submitting a parcel number or a mailing address (like a P.O. Box) instead of the physical street address where the work will occur causes significant delays. The permit system cross-references the address with the city's property database for zoning and utility checks. An un-matchable address halts review. For example, entering '123 Main St' without the suite or unit number for a multi-tenant building will trigger a correction request, adding 3–5 days. Use the full, formatted address as it appears on your lease or utility bill.
3. Misclassifying the Scope of Work
Selecting a broad category like 'Repair' when the work involves new fixture installations or changes to the water supply line leads to underpayment of fees and an incorrect permit type. San Antonio's fee schedule is based on the valuation and type of work (e.g., 'New Construction,' 'Alteration,' 'Service Repair'). If the valuation is too low for the actual scope, the permit may be revoked during inspection. This mistake can result in re-application, double fees, and a 2–3 week setback. Be precise; list all fixtures, pipe runs, and connections being installed or replaced.

Prepare Application Materials & Professional Design
Gather your completed plumbing permit application, construction plans, and supporting documents. For most restaurant projects, you will need detailed plumbing riser diagrams and fixture schedules stamped by a Texas-licensed professional engineer or architect, confirming compliance with the San Antonio Plumbing Code and International Plumbing Code (IPC). This step is required for all work beyond simple repairs and is the most common cause of initial submission rejection due to inadequate drawings.
Submit Application Through SA ePermits Portal
File your complete application packet electronically via the City of San Antonio's SA ePermits system. You must register an account, upload all plans in PDF format, and enter detailed project information, including contractor license details if applicable. You will pay the government filing fee online, which is based on the total fixture count and valuation of the plumbing work. Applications submitted in person at the Development Services Department (DSD) counter are also accepted but may involve longer in-person wait times.
Plan Review by DSD Plumbing Division
The DSD Plumbing Division reviews your submitted plans for code compliance. The review checks fixture counts, pipe sizing, venting, backflow prevention, grease interceptor requirements, and connection to city sewer/water. Reviewers will issue comments if corrections are needed. This is where most delays occur; a complex commercial kitchen layout with gas lines and specialized equipment often requires at least one round of revisions. You can check review status in the SA ePermits portal.

See All RequirementsProcessing time varies significantly based on project complexity and city review workload, per the Development Services Department. Simple, complete applications for minor repairs may be reviewed in days, while complex new construction plans can take several weeks. Contact the DSD Plan Review counter for current processing estimates before scheduling work.
The official government filing fee range is $0–$0, according to the City of San Antonio Fee Schedule. This does not include costs for required plan reviews, Backflow Prevention Device Certification testing, or inspector travel fees for failed inspections. Contact Development Services Department customer service to confirm any non-permit fees associated with your specific project.
No. Permits are issued for a specific property and project scope, as stated in the San Antonio Plumbing Code. If you move locations, you must apply for a new permit. For renovations at your new site, you'll also likely need a separate Building Permit if structural work is involved.
Plumbing permits themselves are not renewed; they are valid until the approved work passes final inspection. However, if work does not commence within 180 days, the permit may expire per city ordinance, requiring a re-application. Certain installed devices, like backflow preventers, require annual testing and certification, which is a separate process.
A city inspector visits the site to verify the installed plumbing matches the approved plans and meets code. They will check pipe sizing, material, slope, venting, fixture connections, and any required backflow prevention assemblies. If the work fails, the inspector provides a correction notice detailing deficiencies, which must be fixed before a re-inspection (often incurring an additional fee).
