Grease Trap/Interceptor Permit in Los Angeles, California (2026)
Without a Grease Trap/Interceptor Permit from the Los Angeles Department of Public Works (LADPW), your restaurant's wastewater system won't pass inspection—and your landlord or lender won't sign off until it does. This permit (also called a grease interceptor permit or FOG control permit) certifies that your grease separation equipment meets LA's pretreatment standards. Key facts:

Why You Need a Grease Trap/Interceptor Permit
Los Angeles restaurants are required to install and maintain a grease trap or grease interceptor under the Los Angeles Municipal Code (LAMC) § 64.30, which governs fats, oils, and grease (FOG) discharge into the city's sewer system, and is enforced by the LA Sanitation & Environment (LASAN) Pretreatment Program. Installation work that affects sewer laterals or requires trenching under public sidewalks or roadways also triggers review under LAMC Title 62 (public works) and may require a separate encroachment permit from the Bureau of Engineering. Before your water or sewer connection is approved, LASAN inspectors verify that a properly sized and permitted grease interceptor is in place — meaning your restaurant cannot legally receive a certificate of occupancy or pass a final health inspection without this permit in hand.
Operating without a valid Grease Trap/Interceptor Permit — or failing to maintain the device in compliance with LASAN's cleaning and manifesting schedule — exposes your business to a compounding set of consequences:
- Sewer service disconnection — LASAN can order the physical disconnection of your sewer lateral, shutting down kitchen operations immediately
- Administrative fines — LASAN issues notices of violation with fines assessed on a per-day basis until the deficiency is corrected; contact LASAN to confirm current fine amounts, as they are subject to annual revision
- Mandatory remediation costs — you bear full liability for any FOG-related blockage or spill in the public sewer, including cleanup, pipe jetting, and third-party contractor fees
- Permit revocation — LASAN can revoke your pretreatment permit, which in turn triggers suspension of your LA County Health permit and forces closure
- Insurance and lease exposure — most commercial kitchen leases require tenants to maintain all required environmental permits in good standing; a lapsed grease interceptor permit can constitute a lease default, and some commercial general liability policies exclude FOG-related sewer damage claims when the required permit is not current
Legal code: Local sewer use regulations, water connection requirements, road/sidewalk ordinances, grease discharge limits
Recent update: As of 2024, LASAN updated its FOG Control Program inspection protocols to require electronic submission of grease interceptor service manifests through the city's online portal — paper manifests are no longer accepted for new permit applications in Los Angeles.
Who Needs a Grease Trap/Interceptor Permit?
| Type | Required | Notes |
|---|---|---|
| Restaurant (Full-Service) | Required | Full-service restaurants discharge fats, oils, and grease (FOG) from cooking operations and are explicitly required to install and permit a grease interceptor under Los Angeles Municipal Code § 64.30 and the LA Sanitation FOG Control Program. |
| Bar / Nightclub | Required | Bars and nightclubs that prepare or serve food — including bar snacks, appetizers, or full menus — generate FOG discharge and must obtain a grease interceptor permit per LA Sanitation's FOG Control Program requirements. |
| Food Truck | Required | Mobile food facilities operating in Los Angeles must connect to an approved commissary that holds a valid grease interceptor permit; the food truck itself must also comply with LA County Environmental Health grease waste disposal requirements at the commissary level. |
| Coffee Shop / Café | Required | Coffee shops that use espresso machines, dishwashers, or prepare any food items with oil or dairy discharge FOG into the sewer system and are subject to LA Sanitation's FOG Control Program interceptor requirements. |

27 of 32 auto-filledLegal Business Name
textEnter the full legal name of your business exactly as it appears on your Articles of Incorporation, DBA filing, or business license — not your trade name or 'doing business as' name unless that is your registered legal name.
COMMON MISTAKE: Entering a trade name or shortened nickname (e.g., 'Joe's Tacos' instead of 'JT Restaurant Group LLC') will cause a name mismatch with LA Sanitation's business records and trigger a rejection requiring resubmission.
Food Service Establishment Type
textSelect or enter the category that best describes your food service operation as defined by the LA County Health Department classifications — common values include 'Full-Service Restaurant,' 'Fast Food Restaurant,' 'Bakery,' 'Caterer,' or 'Institutional Food Service.'
COMMON MISTAKE: Using a vague or self-invented category (e.g., 'food place' or 'eatery') instead of an LA Sanitation-recognized establishment type will delay review because the reviewer cannot match your grease trap sizing requirements to the correct FOG loading table.
Street Address
textEnter the physical street address of the restaurant or food service facility where the grease trap/interceptor is installed or will be installed — this must match the service address on file with LA Sanitation and Bureau of Sanitation (LASAN).
COMMON MISTAKE: Entering a mailing address, P.O. Box, or corporate headquarters address instead of the actual facility address will cause LASAN inspectors to be dispatched to the wrong location, resulting in automatic rejection and re-inspection fees.
City
textEnter the incorporated city name where the facility is located — for properties within the City of Los Angeles boundaries, enter 'Los Angeles'; if your facility is in an unincorporated area or a separate municipality (e.g., Culver City, Beverly Hills), enter the correct city name, as jurisdictional authority over the permit may differ.
COMMON MISTAKE: Entering 'LA' as an abbreviation instead of 'Los Angeles,' or confusing a nearby incorporated city with the City of Los Angeles, can route your application to the wrong reviewing agency and delay processing by 2–4 weeks.
State
textEnter 'CA' or 'California' — this field is required for record-keeping but is rarely the source of rejections given that this permit is issued exclusively within California.
COMMON MISTAKE: Leaving this field blank can trigger an incomplete application notice from LASAN's automated form validation, adding unnecessary processing delays.
ZIP Code
textEnter the 5-digit USPS ZIP code for the physical facility address — LASAN uses ZIP codes to route applications to the correct district office and to verify service area jurisdiction.
COMMON MISTAKE: Using a ZIP+4 format without the hyphen separator, or entering the ZIP code for your mailing address rather than your facility address, can cause a jurisdiction mismatch that requires manual correction by a LASAN reviewer.
Food Preparation Activities
textDescribe all cooking and food preparation methods performed at the facility that generate fats, oils, and grease (FOG) — include activities such as deep frying, grilling, sautéing, wok cooking, and any industrial dishwashing, as LASAN uses this information to verify your grease interceptor sizing meets the required capacity per the FOG Control Program.
COMMON MISTAKE: Listing only primary cooking methods while omitting high-FOG activities like deep frying or hood filter cleaning will cause LASAN to flag the interceptor sizing as potentially undersized, triggering a plan check revision and adding 3–6 weeks to approval.
Types of Food Served
textList the specific categories of food your establishment serves — such as 'fried chicken, burgers, breakfast items with eggs and bacon' — because LASAN reviewers cross-reference food types with expected FOG generation rates to validate the interceptor capacity you are requesting.
COMMON MISTAKE: Entering a broad, uninformative description like 'American food' or 'mixed cuisine' instead of specific food categories forces the reviewer to request supplemental documentation, which can delay permit issuance by 2–3 weeks.
Estimated Daily Wastewater Volume (gallons)
textEnter the estimated total volume of wastewater generated daily by kitchen operations in gallons per day (GPD) — LASAN uses this figure, alongside FOG content levels, to calculate the minimum required grease interceptor capacity per the Wastewater Ordinance; if you are unsure, consult your plumber or use LASAN's FOG sizing worksheet available on the Bureau of Sanitation website.
COMMON MISTAKE: Entering an unrealistically low wastewater volume (e.g., 50 GPD for a full-service restaurant) to qualify for a smaller, less expensive interceptor is a common error that LASAN reviewers are trained to flag — underreporting triggers an automatic plan check revision and may result in a field inspection before approval.
FOG Content Level
textEnter the estimated fats, oils, and grease (FOG) concentration level in your wastewater, typically expressed as milligrams per liter (mg/L) or as a qualitative category (Low/Medium/High) per LASAN's FOG Control Program guidelines — this value directly determines whether an under-sink grease trap or a larger outdoor grease interceptor is required under Los Angeles Municipal Code § 64.30.
COMMON MISTAKE: Selecting 'Low' FOG content for high-volume frying operations (e.g., a fried chicken restaurant or donut shop) contradicts the food preparation activities listed elsewhere on the form, causing an internal data conflict that LASAN reviewers will flag as a material discrepancy requiring correction before approval.

Top 5 Grease Trap/Interceptor Permit Mistakes
1. Submitting Incorrect or Incomplete Grease Interceptor Sizing Calculations
The most common rejection trigger is providing sizing calculations that don't match the LA County Sanitation Districts' design standards — specifically, failing to account for peak flow rates, fixture unit counts, or required minimum capacity (typically 1,000–2,000 gallons for full-service restaurants). Reviewers will reject applications where the calculated interceptor size doesn't align with the number of kitchen fixtures listed elsewhere on the form. Before submitting, cross-check your sizing worksheet against the LA County Industrial Waste Section's grease interceptor sizing guidelines, and have a licensed plumber or engineer confirm the calculations match your floor plan. Not legal advice.
2. Using the Business Mailing Address Instead of the Installation Site Address
Entering a corporate office address, P.O. box, or home address in the 'installation location' field is a frequent error that flags the application for manual review and adds 2–3 weeks to processing. The permit must reflect the physical street address of the restaurant where the grease trap or interceptor will be installed — not the owner's billing address. Double-check that the address on your application exactly matches the address on your building permit and your lease agreement, including suite or unit number.
3. Failing to Attach Approved Plumbing or Building Plans
The LA Bureau of Sanitation and the Department of Building and Safety require stamped, approved plumbing plans showing the interceptor's location, connection to the drainage system, and access points — submitting without these attachments results in an automatic incomplete-application notice. A common mistake is attaching preliminary or hand-drawn sketches rather than plans that carry a plan-check approval number from LADBS. Retrieve your approved plan set from the LADBS permit portal and include the plan-check number on the application cover sheet before submitting.

Determine if your food service establishment requires a grease interceptor under Los Angeles County Code Title 20
Check LA County Code Title 20, Chapter 20.12 to confirm your restaurant size and type triggers the grease interceptor requirement — establishments with food prep sinks, floor drains, or dishwashing equipment typically require one. Contact LADPW Environmental Programs Division (888-LA-TRASH or ladpw.org) to verify your specific property; they can confirm requirements in 1–2 business days. Documentation of this determination protects you if an inspector later disputes the requirement.
Select appropriate grease interceptor type (gravity grease interceptor minimum 750 gallons or grease removal device)
LA County requires either a gravity grease interceptor with a minimum 750-gallon capacity (typical for most restaurants) or an approved grease removal device (GRD). Your plumber must confirm which type complies with your kitchen layout and flow rate — gravity interceptors are standard but require dedicated floor space, while GRDs are compact but must be NSF-certified. Have your plumber provide written confirmation of the type selected before design begins.
Hire a licensed plumber to design and install the grease interceptor system
Obtain bids from at least two California-licensed plumbers (verify license at CSLB.ca.gov) experienced with LA County grease interceptor installations. The plumber must follow LA County plumbing code and provide scaled system drawings; most plumbers charge $500–$2,000 for design and $3,000–$8,000 for installation depending on interceptor type and location. Confirm the plumber will handle permit application submission and inspection coordination — many experienced plumbers do this as part of their service.

See All RequirementsProcessing timelines for grease trap/interceptor permits vary based on inspection scheduling and application completeness. Contact LADPW (Los Angeles Department of Public Works) for current permit processing timelines, as they manage both the permitting and inspection phases. Delays commonly occur when initial inspections reveal non-compliant installations — plan for 2–4 weeks minimum from application submission to final approval, though expedited review may be available for certain circumstances.
Los Angeles does not currently charge a separate government filing fee for grease trap/interceptor permits; however, you are responsible for the cost of the grease trap installation itself, professional inspections, and any required repairs to meet City standards. Grease trap systems typically range from $1,500–$5,000+ depending on size, material (steel vs. fiberglass), and complexity of installation. Verify current fee policy with LADPW at (213) 485-5900 or on the City's Department of Public Works website. Not legal advice — contact LADPW to confirm.
Grease trap/interceptor permits are location-specific and tied to the restaurant's physical address and plumbing infrastructure — they cannot be transferred to a new location. If you relocate your restaurant, you must apply for a new grease trap/interceptor permit at the new address and have the system inspected and approved before opening. You should also apply for a new Business Tax Registration Certificate reflecting your new address, as the City tracks permits by business location.
Grease trap/interceptor permits in Los Angeles do not require periodic renewal — the permit remains valid as long as the system remains in service and continues to meet City compliance standards. However, you must maintain the grease trap through regular pumping (typically every 30–90 days, depending on usage) and ensure it passes annual or bi-annual health inspections as part of your restaurant's food service compliance. If your system is modified, upgraded, or replaced, contact LADPW to determine whether a new permit application is required.
During the grease trap inspection, an LADPW or certified inspector will verify that your system meets Los Angeles plumbing and environmental standards — checking for proper sizing, installation depth, access points, and compliance with the California Plumbing Code. The inspector will confirm that the trap is connected to the sewer line correctly and that it cannot overflow or discharge grease into storm drains or the environment. If deficiencies are found, you will receive a written report detailing required corrections; once repairs are completed, you must schedule a re-inspection to obtain final approval. This inspection is often coordinated with your Building Permit final inspection if you are opening a new restaurant or making major renovations.
