Why You Need a Grease Trap/Interceptor Permit
The City of Houston's Grease Trap/Interceptor Permit is a mandatory requirement primarily under the City of Houston Code of Ordinances § 47-1, which governs wastewater management and sewer use. This ordinance, enforced by the Department of Public Works and Engineering (PWE), specifically prohibits the discharge of fats, oils, and greases (FOG) in amounts that could obstruct public sewers or interfere with the operation of the city's wastewater treatment facilities. The permit process is the city's formal mechanism to review and approve the design, capacity, and installation of your grease control equipment before you connect to the municipal sewer system, ensuring compliance from day one.
Operating a food service establishment without this permit or failing to maintain your grease interceptor carries significant and escalating consequences. Common penalties enforced by Houston PWE inspectors include:
- Service disconnection: The city can physically disconnect your sewer line, halting all operations until the violation is corrected and fines are paid.
- Substantial fines: While specific dollar amounts vary by violation severity and duration, fines are assessed per day of non-compliance and can accumulate into thousands of dollars, creating a severe financial burden.
- Required remediation: You may be forced to excavate and replace or upgrade improperly installed equipment at your own expense, plus pay for any city-performed sewer cleaning necessitated by your discharge.
- Permit revocation: For repeated or egregious violations, the city can revoke your operating permits, effectively shutting down your business until a completely new application is submitted and approved.
Legal code: Local sewer use regulations, water connection requirements, road/sidewalk ordinances, grease discharge limits
Recent update: In recent years, Houston PWE has increased its use of remote video inspections for grease interceptor installations and repairs to accelerate permit close-outs, though in-person inspections are still commonly required for initial installations.
Who Needs a Grease Trap/Interceptor Permit?
| Type | Required | Notes |
|---|---|---|
| Restaurant (Full-Service) | Required | Required per Houston Code of Ordinances § 47-11 because these facilities generate fats, oils, and grease (FOG) from food preparation, dishwashing, and floor drains. |
| Bar / Nightclub | Required | Required if the establishment has a kitchen or food service component, as it discharges grease-laden wastewater into the city sewer under the city’s FOG control program (Houston Code § 47-11). |
| Food Truck | Not Required | Not required for the mobile unit itself, but the commissary kitchen where it operates must have a permitted grease interceptor, as the truck connects to that facility’s waste system for cleaning. |
| Coffee Shop / Café | Not Required | Typically exempt unless they have a full kitchen preparing greasy foods; beverage-only operations with minimal food prep (e.g., pastries) do not trigger the requirement under standard thresholds. |

20 of 24 auto-filledLegal Business Name
textEnter the exact, full legal name of your business entity as it appears on your Texas Secretary of State registration or Assumed Name Certificate (DBA) filing.
COMMON MISTAKE: Using a trading name (like 'Joe's Diner') instead of the registered legal name (like 'JDH Houston, LLC'), which causes document mismatch and delays.
Business Physical Address
textEnter the complete, physical street address where the grease interceptor will be installed, which must match the address on your Houston Food Service Permit and Certificate of Occupancy.
COMMON MISTAKE: Entering a mailing address, P.O. Box, or owner's home address, which is grounds for immediate rejection by Houston Public Works.
Ownership Proof Available
checkboxCheck this box to affirm you possess documentation proving legal ownership or right to operate at the business address, such as a lease or deed.
COMMON MISTAKE: Leaving the box unchecked because the form requires an affirmative declaration; an unchecked box can be interpreted as 'no' and stall the application.
Ownership Documentation
textList the specific documents you will submit as proof, such as 'Lease Agreement between [Owner] and [Business Name]' or 'Warranty Deed for [Address]'.
COMMON MISTAKE: Writing vague terms like 'lease' or 'deed' without specific parties and addresses, which fails to meet Houston's documentation specificity requirement.
Current Business License Status
checkboxCheck this box only if you already hold a valid, current City of Houston Food Service Operating Permit or equivalent city business license for this address.
COMMON MISTAKE: Checking the box if you have only applied for but not yet received the permit, which constitutes a false statement and leads to permit revocation.
Business License or Operating Permit
textEnter the exact permit number and issuing authority, for example: 'City of Houston Food Service Permit #HOU-FS-123456'.
COMMON MISTAKE: Listing an expired permit, a Harris County permit instead of a City of Houston permit, or omitting the permit number entirely.
Establishment Type
textSpecify the primary business activity, such as 'Full-Service Restaurant', 'Fast Food', 'Catering Kitchen', 'Bakery', or 'Food Truck Commissary'.
COMMON MISTAKE: Using overly broad or non-standard terms like 'eatery' or 'food place', which do not align with Houston's classification system for waste calculations.
Waste Generation Activities
textDescribe all kitchen activities that generate Fats, Oils, and Grease (FOG), such as 'deep frying, grill cleaning, dishwashing, and floor mopping'.
COMMON MISTAKE: Omitting major activities like 'dishwashing from a 3-compartment sink' or 'floor drain runoff', which underestimates FOG load and leads to undersized interceptor requirements.
Waste Generation Frequency
textState how often grease-laden wastewater is discharged, such as 'continuous during operating hours' or 'intermittent, 4 times per day'.
COMMON MISTAKE: Writing 'daily' instead of specifying if it's continuous or in batches; this detail is critical for Houston's hydraulic loading calculations.
Grease System Type
textSpecify the model and type of grease control device, such as 'Gravity Grease Interceptor (GGI), 1000-gallon capacity' or 'Automatic Grease Recovery Unit (AGRU), Model XYZ'.
COMMON MISTAKE: Listing a 'grease trap' (typically under 50 gpm) when Houston code requires a 'grease interceptor' (over 50 gpm) for most restaurants, resulting in an automatic plan rejection.

Top 5 Grease Trap/Interceptor Permit Mistakes
1. Submitting an Incomplete or Unsealed Plumbing Plan
Omitting the licensed professional's stamp and signature on the plumbing drawings is a top rejection reason. The Houston Public Works Department requires a wet-signed and sealed plumbing plan showing the exact trap location, pipe sizes, and drainage layout. Without this, your application is considered incomplete and is returned, which can add 2-4 weeks to your timeline. Hire a Texas-registered plumber to prepare and seal the drawings before submission.
2. Inaccurate Capacity Calculations or Trap Sizing
Using generic fixture counts or the wrong calculation method leads to an undersized trap, which will fail review. The permit requires sizing based on the Houston Plumbing Code (Chapter 10) using fixture discharge rates for your specific sinks, dishwashers, and floor drains. For example, listing a 20-gallon-per-minute (gpm) trap for a kitchen with a commercial dishwasher that needs 35 gpm causes immediate rejection and requires a full re-submission with corrected engineering specs.
3. Incorrect Business/Property Information on Form G-11
Entering the restaurant's trade name (DBA) instead of the legal business name registered with the Texas Secretary of State, or using a P.O. Box for the physical address, triggers a mismatch with city records. The Houston Wastewater Division cross-checks this data. For instance, listing 'BBQ Palace' when your LLC is 'Houston Smokehouse, LLC' will cause a delay for verification, adding 1-2 weeks. Always use the exact legal name and the street address of the food service establishment.

Determine permit type: Generator Registration (food establishment) or Generator Permit (non-food establishment)
Review Chapter 36 of the Houston Code of Ordinances to identify your establishment type. Food establishments (restaurants, cafeterias) require a Generator Registration, while non-food grease generators (car washes, laundromats) need a Generator Permit. The Health Department rejects applications submitted under the wrong type, which can delay your process by 1–2 weeks. Gather your lease, business license, and a preliminary kitchen layout to verify your classification.
Complete appropriate application form for your establishment type
Download the correct PDF form from the Houston Health Department’s online portal. The Generator Registration application has 45 fields; ApronPrep auto-fills 33. You must provide detailed kitchen schematics showing all grease-producing fixtures, plumbing connections, and the proposed trap/interceptor location. Missing or unclear diagrams are the top cause of rejection. Plan to spend 2–3 hours gathering floor plans, fixture specs, and contractor information.
Submit application to Houston Health Department, Consumer Health Services Bureau
File your completed packet (application, floor plans, fixture list) via the city's online submission portal or by mail to 8000 North Stadium Drive, Houston, TX 77054. You must include proof of business registration (certificate of occupancy or state business filing). In-person submissions can expedite initial review but are not required. Applications submitted without proof of business registration are held for 5–10 business days until documentation is provided.

See All RequirementsProcessing times are set on a case-by-case basis by the Houston Health Department. Per the department's application guide, you must contact the Bureau of Consumer Health Services directly for current timelines, as they depend on inspection scheduling and plan review. This process typically runs concurrently with your Building Permit review, so plan accordingly.
There is no separate government filing fee for the permit itself, per the Houston Code of Ordinances. However, costs are incurred through required plan reviews and inspections conducted by the Health Department. Not legal advice — verify specific assessment fees with the Houston Health Department.
No, permits are specific to the location and plumbing configuration for which they were approved. If you move or remodel, you must apply for a new permit. This new application will trigger a fresh plan review and inspection, similar to the initial process for a Certificate of Occupancy.
The permit itself does not have a standard annual renewal. Ongoing compliance is enforced through mandatory grease interceptor maintenance and annual waste hauler reports submitted to the Health Department. Contact the department to confirm current reporting requirements and inspection frequency for your facility.
A Health Department inspector verifies the interceptor's installation matches approved plans, checks for proper size/capacity, and ensures correct plumbing connections. They also confirm the unit is accessible for service and that a maintenance log is onsite. Failure can delay all related permits, so ensure your Plumbing Permit work is complete and signed off first.
