Why You Need a Plumbing Permit
In Dallas, a Plumbing Permit is legally mandated for almost all plumbing work on a commercial building under Chapter 52, Article VI of the Dallas City Code and the locally enforced Texas Plumbing License Law (Title 8, Occupations Code, Chapter 1301). The Dallas Department of Sustainable Development and Construction (DSDC) administers these state and local codes to ensure systems are installed to prevent health hazards like contamination and gas leaks, meet water conservation standards, and comply with the Texas Accessibility Standards. This permit is a non-negotiable checkpoint before you can cover walls or connect to city water and sewer mains.
Starting plumbing work without this permit triggers immediate enforcement, which can halt your entire project and lead to significant financial penalties. The DSDC can issue a stop-work order, freezing all construction. Common consequences include:
- Daily fines until compliance is achieved, as stipulated by Dallas City Code.
- Certificate of Occupancy denial, meaning you cannot legally open your restaurant to the public.
- Required demolition of completed work for inspection, at your own expense, to verify code compliance.
- Voided warranties or insurance claims if non-permitted work causes damage or fails.
- Lease violations if alterations are not properly permitted, potentially putting your tenancy at risk.
Legal code: State building code (locally administered), local building ordinances, state accessibility code
Recent update: In 2025, Dallas DSDC expanded its online permit portal to accept applications for a broader range of commercial plumbing projects, reducing the previous in-person submission requirement for initial filings.
Who Needs a Plumbing Permit?
| Type | Required | Notes |
|---|---|---|
| Restaurant (Full-Service) | Required | Required because Dallas plumbing code § 26-1.3 mandates a permit for installation or alteration of any plumbing system, which includes commercial kitchens, bars, and multiple restrooms. |
| Bar / Nightclub | Required | Required for any new or altered plumbing serving bar sinks, prep sinks, ice machines, or restroom facilities, per Dallas Construction Code § 26. |
| Food Truck | Required | Typically required for the permanent plumbing system installation during the vehicle's build-out, but mobile unit plumbing is often covered under the Texas Department of State Health Services' plan review for the commissary. |
| Coffee Shop / Café | Required | Required for installing or modifying plumbing for espresso machines, commercial dishwashers, triple-sink compartments, and restrooms, as regulated by Dallas's plumbing ordinances. |

22 of 27 auto-filledScope of Work Description
textEnter a brief, clear description of all plumbing work, specifying locations (e.g., 'install grease interceptor and new water heater line for rear kitchen prep sink').
COMMON MISTAKE: Listing only a general term like 'plumbing'—the reviewer needs specifics to assign the correct valuation and required inspections.
Work Includes Kitchen Sinks
checkboxCheck this box if your project involves installing, relocating, or replacing a commercial kitchen sink (any fixture used for food prep or dishwashing).
COMMON MISTAKE: Failing to check this when adding a three-compartment sink; this omission can trigger a failed inspection for missing fixture documentation.
Work Includes Grease Trap
checkboxCheck this box if the plumbing work involves a grease interceptor or trap, a critical requirement for any FSE (food service establishment) drain line.
COMMON MISTAKE: Leaving this unchecked when connecting a new fryer or dishwasher drain, which will cause an immediate correction notice from plumbing review.
Work Includes Water Heater
checkboxCheck this box if installing, replacing, or significantly modifying a commercial water heater; this triggers separate gas/electrical and energy code reviews.
COMMON MISTAKE: Checking this for a simple repair like replacing a heating element, which may incorrectly escalate permit valuation and fees.
Maintenance/Repair Only (May Be Exempt)
checkboxCheck only if work is a direct, like-for-like repair (e.g., fixing a leak, replacing a faucet washer) without altering the existing system.
COMMON MISTAKE: Using this exemption for work that changes pipe routing or fixture type, which is a common cause for permit revocation after inspection.
Permit Exemption Notice
textIf you believe the work qualifies as an exempt minor repair, state the specific code section justifying the exemption (e.g., 'Dallas Plumbing Code Section 106.2').
COMMON MISTAKE: Leaving this blank or writing 'N/A' when claiming an exemption; the authority requires a specific legal citation for review.
Installation Type (New/Modification)
textEnter either 'New Installation,' 'Modification/Relocation,' or 'Replacement'—this determines the required plan review level and inspection sequence.
COMMON MISTAKE: Writing 'repair' here, which conflicts with the 'Maintenance Only' checkbox and confuses the routing of your application.
Business Name
textEnter your restaurant's exact, registered legal name as it appears on your state business registration or assumed name certificate.
COMMON MISTAKE: Using a DBA ('Doing Business As') name not formally registered with Dallas County, which causes a mismatch with official records.
Business Address
textEnter the restaurant's complete physical street address where the plumbing work will occur—do not use a P.O. Box or an owner's home address.
COMMON MISTAKE: Including suite or unit numbers in the wrong format (e.g., '#101' vs. 'Suite 101'), which can delay mailing of inspection notices.
Owner/Applicant Name
textEnter the full legal name of the business owner or authorized signatory who will be responsible for the permit.
COMMON MISTAKE: Listing a contractor or property manager's name without proof of authorization, which invalidates the application signature.

Top 5 Plumbing Permit Mistakes
1. Wrong Permit Type (e.g., Rough-In vs. Finish)
Selecting "New Work" when you're only replacing fixtures, or "Alteration" for a new gas line. The Dallas Development Services Department processes these differently, with separate review queues. Submitting under the wrong type sends your application back for correction, adding a minimum of 5-7 business days to your timeline. Always match the permit type to the exact scope: fixture replacement, water heater, gas piping, or sewer line.
2. Missing or Incorrect Contractor License Details
Entering the business name without the state license number, or using an expired or out-of-county license. Dallas requires the Master Plumber's Texas State Board of Plumbing Examiners (TSBPE) license number to be active and registered with the city. Applications without a valid, Dallas-registered license are rejected immediately. Verify your plumber's current TSBPE status and Dallas registration before applying.
3. Vague or Incomplete Scope of Work Description
Writing "repair kitchen sink" instead of "replace 1.5" basket strainer, tailpiece, and P-trap for a double-bowl kitchen sink." Reviewers need precise details to determine if the work complies with the plumbing code (UPC). Vague descriptions trigger a request for additional information (RFI), halting review for 10-14 days. Be specific: list each fixture, pipe material, size, and location.

Step 1: Determine if your plumbing work requires a permit. Kitchen sinks and grease traps in restaurants require permits; simple maintenance/repair of existing fixtures may be exempt.
Before you file, confirm your specific project triggers a permit by checking the Dallas Plumbing Code, Chapter 54 (based on the 2021 International Plumbing Code). For restaurant build-outs, installing new fixtures like a three-compartment sink, grease interceptor, or water heater always requires a permit. Replacing a faucet on an existing sink typically does not. A clear scope definition prevents wasting 1-2 weeks on an unnecessary application submission.
Step 2: Contact Dallas Building Inspection Division by phone (214-948-4480) or visit dallas.gov to obtain the plumbing permit application form.
Call the Division or visit the Development Services page at dallas.gov to download Form B-15 (Plumbing Permit Application). Having your contractor's Texas State Plumbing License number and your restaurant's address ready will speed up this request. The form is free, but requesting a mailed copy can add 3-5 business days versus an instant download.
Step 3: Complete the plumbing permit application with project details, including scope of work (kitchen sink installation, grease trap installation/modification).
Fill out all 25+ fields on Form B-15, including contractor information, valuation of work, and detailed description of the plumbing system. You must attach scaled plumbing plans showing fixture locations, pipe sizes, and grease trap details. Incomplete or unclear plans are the top reason for plan review rejection, which can add 10-15 business days to your timeline.

See All RequirementsProcessing time varies significantly based on project complexity, from minor repairs to full system installations, and the completeness of your application. For a standard review, the Dallas Department of Development Services typically requires a few business days. However, plan reviews for complex work can extend the timeline. Always contact the Dallas Development Services Department to confirm the current processing window for your specific scope.
Government filing fees range from $214 to $4,480 per the Dallas Department of Development Services fee schedule. The final cost is calculated using specific valuation formulas based on the project's scope and plumbing fixture count. For an exact fee, you'll need the project details reviewed, similar to the valuation process for a separate Building Permit. Not legal advice — verify final fees with Dallas Development Services.
No, plumbing permits are site-specific and tied to the property address listed on the original application. If you move your business, you must apply for a new permit at the new location, which will restart the entire review and inspection process. This requirement ensures each facility's plumbing system is independently approved for compliance with Dallas City Code, just as a new location would require its own Certificate of Occupancy.
Plumbing permits in Dallas are not renewable; they are one-time authorizations for a specific construction project. Once the permitted work passes final inspection, the permit is closed. Ongoing compliance for the installed system falls under general maintenance and is subject to periodic city inspections, not permit renewal. Contact Dallas Development Services to understand inspection schedules for existing facilities.
A city inspector verifies that all installed work matches the approved plans and complies with the Dallas Plumbing Code and the International Plumbing Code (IPC). They will check pipe sizing, materials, fixture installations, venting, and backflow prevention. The inspector will either approve the work or issue a correction notice listing specific deficiencies that must be fixed before a reinspection, which may incur additional fees.
