Why You Need a Grease Trap/Interceptor Permit
In the City of Tulsa, Oklahoma, a Grease Trap/Interceptor Permit is required as a condition for obtaining a building or plumbing permit for any food service establishment, as mandated by the Tulsa Revised Ordinances, Title 43, Chapter 101, which covers plumbing regulations, and by adherence to local sewer use policies set by the Tulsa Metropolitan Utility Authority (TMUA). The permit is issued by the Tulsa Planning & Development Department, Engineering Services Division, to ensure that the design, installation, and maintenance of grease control devices meet specific standards to protect the public sewer system. These ordinances require that any fixture discharging grease-laden wastewater, including sinks, dishwashers, and floor drains, must be routed through a properly sized and permitted interceptor before entering the municipal sewer lines.
Failure to obtain and comply with this permit carries significant practical and financial consequences. The City of Tulsa and TMUA enforce these regulations to prevent blockages (known as “fatbergs”) in the sewer system, which can cause costly overflows and environmental damage. The most common penalties include:
- Daily Fines: Civil penalties for illegal discharge, with fines accumulating daily until the violation is corrected. The specific amounts are set by the TMUA enforcement schedule.
- Cease-and-Desist / Shutdown Risk: The Engineering Services Division can issue a stop-work order on construction, and the TMUA can require the immediate cessation of all wastewater discharge, effectively halting restaurant operations until the proper interceptor is installed and permitted.
- Lease and Insurance Implications: Most commercial leases and business insurance policies require compliance with all local codes. Operating without this permit can void these agreements, leaving you liable for any sewer backup damages and potentially in breach of your lease.
Legal code: Local sewer use regulations, water connection requirements, road/sidewalk ordinances, grease discharge limits
Recent update: As of early 2026, the Tulsa Planning & Development Department now requires all new grease interceptor permit applications to include a signed affidavit from the plumbing contractor certifying the installation meets current TMUA specifications, a change from the previous practice of relying solely on city inspections.
Who Needs a Grease Trap/Interceptor Permit?
| Type | Required | Notes |
|---|---|---|
| Restaurant (Full-Service) | Required | Required per City of Tulsa Code § 51-63; any facility preparing food on-site and discharging grease-laden wastewater to the sanitary sewer must obtain this permit. |
| Bar / Nightclub | Required | Required because these establishments typically operate a kitchen for food service, which discharges grease-laden wastewater covered under City of Tulsa Code § 51-63. |
| Food Truck | Required | Required; all mobile food units must be registered with a permitted stationary commissary, which itself must have a valid grease trap/interceptor permit from the Tulsa jurisdiction where it's located. |
| Coffee Shop / Café | Required | Required if the facility has a kitchen preparing food (e.g., sandwiches, pastries) that generates grease-laden wastewater, as stipulated by City of Tulsa regulations. |

15 of 18 auto-filledConstruction/Installation Address
textEnter the precise street address of the commercial property where the grease trap or interceptor is being installed—this must match the legal site address on file with the City of Tulsa, not a P.O. box.
COMMON MISTAKE: Using the restaurant's mailing address or a corporate office address instead of the physical installation location can cause the application to be rejected by the inspection department.
Property Owner's Name
textEnter the full legal name of the individual or entity that holds title to the property where the grease trap is installed, as recorded on the deed—if owned by an LLC, use the LLC's registered name.
COMMON MISTAKE: Entering the business operator's name when the property is owned by a different entity (like a holding company) will trigger a rejection because the City of Tulsa Plumbing & Gas Codes require verification of ownership.
Business or Restaurant Name
textEnter the exact, registered name of the food service business operating at the installation address—this is the name that will appear on your City of Tulsa business license.
COMMON MISTAKE: Leaving this blank or entering a 'Doing Business As' (DBA) name that hasn't been formally registered with the city clerk's office can delay permit approval.
City of Tulsa Account Number
textEnter the unique 6- to 10-digit account number assigned to your property for water/sewer billing by the City of Tulsa—find it on your most recent utility bill or call the Customer Care Center.
COMMON MISTAKE: Using an old, disconnected, or personal residential account number instead of the active commercial utility account for the installation address will cause the application to be returned for correction.
Number of Plan Sets Submitted
textEnter the total number of identical, stamped plan sets you are physically submitting for review—typically 2 or 3 sets for a grease trap permit, as required by the Tulsa Development Services Department.
COMMON MISTAKE: Entering '1' when the city requires multiple sets for routing to different departments (Plumbing, Environmental, etc.) will delay review until the correct number is provided.
Pages Per Plan Set
textEnter the count of pages contained in a single, complete set of your submitted plans—include all site plans, plumbing details, manufacturer cut sheets, and specification pages.
COMMON MISTAKE: Under-counting pages (e.g., forgetting addenda or specifications) can lead to the city flagging your submission as incomplete, adding 1–2 weeks to your timeline.
Licensed Plumber/Contractor Name
textEnter the full business name of the licensed plumbing contractor performing the installation, exactly as it appears on their City of Tulsa contractor's license—this is a mandatory field for all plumbing permit applications.
COMMON MISTAKE: Listing an unlicensed contractor or a general contractor without a specific plumbing endorsement will result in an immediate rejection, as per Tulsa's plumbing code § 4-102.
Contractor Street Address
textEnter the contractor's primary business street address—this must be their physical place of business, not a P.O. box, for verification by the city's Licensing Division.
COMMON MISTAKE: Using a P.O. box or a residential address for the contractor can trigger a verification failure and pause the permit application until corrected.
Contractor City
textEnter the city where the licensed plumbing contractor's business is physically located—ensure it matches the city listed on their official license registration.
Contractor State
textEnter the two-letter state abbreviation (e.g., 'OK') for the contractor's business address—use the state where their plumbing license is primarily issued.

Top 5 Grease Trap/Interceptor Permit Mistakes
1. Submitting a Generic Pumping Schedule
Leaving the planned pumping frequency field blank or selecting 'per manufacturer' causes the most common rejection. Tulsa's Plumbing & Fuel Gas Code (Title 30, Chapter 5) requires a specific maintenance schedule based on interceptor size and estimated grease waste. List a frequency like 'Every 90 days' based on your projected FOG output. A vague entry triggers a review request, adding 1-2 weeks to your timeline.
2. Incorrectly Listing the Interceptor Manufacturer
Entering the installer's name or 'various' instead of the certified equipment manufacturer results in a correction notice. The permit must list the specific make and model (e.g., 'Zabel M1A-1500') of the interceptor listed on your submitted plans. Using an unapproved or unlisted model leads to immediate rejection. Verify the model is on the approved list from the Tulsa Development Authority's website to avoid this delay.
3. Missing the 'As-Built' Site Plan Attachment
Failing to attach the final, sealed 'as-built' plan showing the exact installed location is a top reason for permit closure. The application requires this specific document, not just the initial conceptual plan. Submitting the wrong drawing type will halt processing until the correct file is provided, which can postpone your final inspection by 3-4 weeks. Double-check that your attached PDF includes the engineer's or architect's seal.

Site Plan & Plumbing Review
Before applying, have a licensed plumber or engineer prepare a detailed site plan showing the proposed grease trap/interceptor location, size (in gallons), and connection points to your kitchen plumbing and the sanitary sewer line. This plan must comply with the <i>2018 International Plumbing Code (IPC)</i>, adopted by Tulsa, and Tulsa's specific amendments. The city's Development Services Department may require a pre-application consultation to review your site's suitability—this is critical for new construction or significant remodels to avoid costly revisions later.
Submit Permit Application Packet
File your complete application packet, including the city's plumbing permit application form, the engineered site plan, and the manufacturer's specification sheets for the selected grease interceptor. Submit these documents to the Tulsa Development Services Department, either online via the city's permitting portal or in person at the One Technology Center. You must include the required <strong>government filing fee</strong> (exact amount varies based on project valuation; contact the department for the current fee schedule). Applications are rejected immediately if they lack the engineered plan or correct fee payment.
Plan Review & Approval
A city plumbing plan reviewer will examine your submission for compliance with IPC standards and local codes, focusing on interceptor sizing calculations (based on fixture units and flow rates), venting, and access for maintenance. This review typically takes several weeks. If revisions are required, you'll receive a correction notice detailing the deficiencies—common issues include undersized interceptor capacity or missing cleanout access details—which can add 2-3 weeks to your timeline.

See All RequirementsProcessing time varies and depends on the completeness of your application and the current workload of the Tulsa Development Services Department. It is essential to submit a complete application, including all required plans and a Building Permit if new construction or plumbing modifications are involved, to avoid delays. Contact Tulsa Development Services for the most current timeline estimate for your specific project.
The City of Tulsa does not list a specific government filing fee for the Grease Trap/Interceptor Permit itself per the city's published fee schedules. However, fees are typically assessed as part of a broader plumbing or building permit review. You should contact Tulsa Development Services to confirm any associated plan review or inspection fees for your project.
No, grease trap/interceptor permits are not transferable between locations. The permit is issued for a specific installation and address based on the approved plumbing plans. A new permit application, including new plans and likely a new Certificate of Occupancy process, is required for any new restaurant location.
The initial installation permit does not typically require renewal. Ongoing compliance is enforced through mandatory maintenance and annual inspection reports submitted to the city's Wastewater Compliance Division. Failure to submit required maintenance records can result in violations and fines, separate from the initial permit.
A city plumbing inspector will verify that the installation matches the approved plans, checking the size, location, and accessibility of the interceptor. They will ensure proper venting, labeling, and that all plumbing connections meet code. Passing this final inspection is a prerequisite for receiving approval to operate the associated food service equipment.
