Restaurant Grease Trap Cleaning
in Los Angeles, CA
Grease traps prevent fats, oils, and grease (FOG) from entering the sewer system. Full traps cause backups, foul odors, and health code violations. Most municipalities mandate a pumping schedule and require disposal manifests.
25,000 kitchens, one sewer system — and LA's warmth never lets grease slow down
Los Angeles is one of the most complex restaurant markets in the world — over 25,000 licensed food establishments spread across 500 square miles of wildly different neighborhoods. For hood cleaning, the key variable isn't the city as a whole but the specific neighborhood and kitchen type. Koreatown runs some of the highest-grease-load kitchens in California, with charcoal and gas wok operations running 12+ hours daily. Downtown's Arts District hosts a dense cluster of high-end restaurants with elaborate kitchen builds. Hollywood and West Hollywood skew toward late-night high-volume operations that accumulate grease faster than the visible hours would suggest. East LA and Boyle Heights have concentrations of Mexican and Latin kitchens — carnitas, birria, and high-output fryers — that put consistent heavy load on hood systems. Each zone has a different cleaning cadence in practice.

Best price for Restaurant Grease Trap Cleaning in Los Angeles
If you find a lower price from a licensed, compliant provider, we'll match it. This is not a race to the bottom — Boh vendors are fully licensed, carry the required CDFA and LA County hauler permits, and issue the mandatory manifest report after every visit. The low price reflects volume efficiency, not corners cut on compliance.
LA's Climate Accelerates FOG Buildup Year-Round
Warm temperatures accelerate the breakdown of fats, oils, and grease in drain lines — meaning LA kitchens accumulate FOG faster than kitchens in colder climates. There is no winter slowdown. High-volume operations in LA often need more frequent pumping than the standard 90-day interval to stay ahead of capacity limits and H2S odor issues.
LA County Sanitation Districts enforce the 25% rule
LA County Sanitation Districts require grease interceptors to be cleaned when grease and solids accumulate to 25% of the interceptor's hydraulic depth. Manifests must be kept for 3 years.

Monthly for most LA kitchens, more often for Koreatown and East LA
Why LA operators call before a health inspector does
Grease trap cleaning in Los Angeles, answered
How often does LA County Sanitation actually require grease trap cleaning
The LA County Sanitation Districts require cleaning whenever grease and solids reach 25% of the trap's hydraulic depth. For high-volume kitchens — Korean BBQ in Koreatown, carnitas operations in Boyle Heights, late-night spots in Hollywood — that threshold hits monthly or faster. Lighter-use kitchens may stretch to every two to three months, but the 25% rule governs, not the calendar.
What happens if I miss a cleaning and a sanitation inspector visits
The LA County Sanitation Districts can issue an FOG violation, impose fines up to $5,000, and in serious or repeat cases move toward sewer connection revocation. An open citation requires documented cleaning and a signed manifest to close — verbal assurances don't satisfy the file.
Does LA's climate affect how fast my trap fills
Yes, significantly. LA's warm year-round temperatures accelerate biological activity in drain lines — there is no cold-weather slowdown that slows FOG accumulation the way it does in northern climates. Kitchens that might pump quarterly in Seattle are often monthly accounts in Los Angeles.
What documents do I need to keep on file after each service
LA County Sanitation Districts require pumping manifests to be retained for three years. Each manifest should identify the service date, trap volume, and the licensed hauler who transported the waste to an approved receiving facility. Gaps in that chain can expose you to the same penalties as skipped cleanings.
Can I use any hauler, or does it have to be a licensed one
The hauler must be licensed to transport FOG waste to an approved facility in California. Using an unlicensed hauler invalidates your manifest — the cleaning is effectively undocumented in the eyes of the LA County Sanitation Districts, regardless of whether the work was done.
My kitchen is in an older strip mall in Koreatown — does that affect the service
Older Koreatown buildings frequently have non-standard trap placements, limited access, and undersized interceptors relative to the cooking load. A charcoal or gas wok operation running 12-plus hours daily can saturate a small trap in under three weeks. Operators in these buildings should expect shorter intervals between cleanings and occasionally need trap resizing discussions.
What's the difference between a grease trap and a grease interceptor
A grease trap is typically a small, under-sink unit sized for lower-volume kitchens. A grease interceptor is a larger below-ground unit, often required for high-volume or multi-station kitchens. LA County Sanitation Districts apply the same 25% threshold to both, but interceptors hold more volume and are pumped by vacuum truck rather than by hand.
Is grease trap cleaning connected to my hood cleaning schedule
They address different parts of the grease pathway. Hood cleaning removes accumulated grease from exhaust systems above the cooking line; grease trap cleaning removes FOG that travels down drain lines after cooking and washing. High-grease kitchens — birria, wok cooking, fryers — need both services on aggressive schedules, and a failure in either one can trigger an inspection violation.
