Grease trap service in Los Angeles costs between $150 and $800 per cleaning for most commercial kitchens, with monthly service contracts ranging from $200 to $1,200 depending on trap size and kitchen volume. LA County enforces some of the strictest fats, oils, and grease (FOG) regulations in California, making regular professional service non-negotiable for restaurants, cafeterias, and food service facilities. This guide breaks down what you'll pay, which providers serve the Los Angeles area, and how to stay compliant with local regulations.
How Much Does Grease Trap Service Cost in Los Angeles?
Los Angeles grease trap service pricing follows a tiered structure based on trap capacity, service frequency, and accessibility. A standard 50-gallon under-sink trap in a small café typically costs $150 to $250 per cleaning, while a 1,500-gallon in-ground interceptor at a high-volume restaurant runs $400 to $800 per pump-out. Emergency cleanings after a backup or health inspection failure can exceed $1,000 due to after-hours labor and expedited scheduling.
Service frequency directly impacts monthly costs. Most LA restaurants require cleaning every 2–4 weeks to meet the 25% capacity threshold mandated by LA County's FOG ordinance. A monthly service contract for a mid-sized restaurant with a 500-gallon trap averages $350 to $600 per month, which includes pump-out, basic maintenance inspection, and compliance documentation. Bi-weekly service increases monthly costs by 40–60%, but prevents overflow violations that carry fines starting at $1,000.
Geographic factors also affect pricing within the LA metro area. Downtown Los Angeles and densely populated commercial districts see higher base rates ($20–40 more per visit) due to parking challenges, restricted access hours, and longer service times. Providers serving outlying areas like San Pedro, Woodland Hills, or Northridge may add fuel surcharges for travel, but face fewer logistical constraints.

| Service Type | Typical Cost Range |
|---|---|
| 50-gallon under-sink trap (monthly service) | $150–$250 |
| 500-gallon in-ground trap (monthly service) | $350–$600 |
| 1,500-gallon interceptor (monthly service) | $500–$800 |
| Bi-weekly service (add 40–60% to monthly rate) | +$140–$360 |
| Emergency/after-hours cleaning | $800–$1,200+ |
| Hydro-jetting (clogged drain lines) | $300–$600 |
LA County FOG Ordinance Requirements
Los Angeles County's FOG ordinance requires all food service establishments to maintain grease traps at no more than 25% capacity at any time. This triggers mandatory cleaning schedules based on kitchen volume — high-volume operations like full-service restaurants typically need service every 14–21 days, while lower-volume establishments like coffee shops may stretch to monthly cleanings. The ordinance applies countywide, including all 88 incorporated cities within LA County boundaries.
Facilities must maintain service records for three years and present them during health inspections. Missing documentation results in immediate violations, even if the trap appears clean. Service providers issue manifests after each pump-out detailing gallons removed, service date, and next recommended cleaning. Keep both physical and digital copies — health inspectors increasingly request electronic records during routine visits.
LA County conducts surprise FOG inspections at food service facilities. Traps exceeding 25% capacity trigger automatic violations with fines starting at $1,000. Repeat violations can result in permit suspension and mandatory daily inspections until compliance is restored.
The City of Los Angeles (serviced by LA Sanitation) enforces additional requirements beyond the county standard. All new or remodeled food facilities installed after 2012 must have grease interceptors sized to handle peak flow rates — typically 1,000 gallons minimum for full-service restaurants. Existing facilities with under-capacity traps face retrofit orders during permit renewals. For broader California compliance context, review our comprehensive FOG compliance guide.
What to Expect from Professional Grease Trap Service
A complete grease trap service visit includes pump-out, inspection, and basic maintenance — not just waste removal. Technicians arrive with vacuum trucks capable of handling solid and liquid waste, pumping the entire trap contents including settled solids that cause most backups. After pump-out, they flush the trap with water, inspect baffles and seals for damage, and document the service with photos and volume measurements.
Professional service includes trap inspection, not just pumping. Technicians should check baffles, gaskets, and inlet/outlet pipes for wear — catching small issues before they become thousand-dollar repairs.
Reputable Los Angeles providers also offer hydro-jetting for drain lines feeding the trap. Grease accumulation in pipes upstream causes slow drainage and odors even when traps function properly. Hydro-jetting uses high-pressure water streams to scour pipe interiors, removing built-up FOG and restoring flow. This supplementary service costs $300–$600 but prevents emergency plumbing calls that disrupt business operations.
Service timing matters in LA's competitive restaurant landscape. Most providers schedule cleanings during off-peak hours (early morning or late night) to minimize disruption. Emergency 24-hour service is standard across major providers, though after-hours rates run 50–100% higher than scheduled appointments. Establish a regular service schedule to avoid premium emergency pricing and maintain consistent compliance.
Schedule grease trap service the same day each cycle (e.g., first Monday of the month). Consistent timing helps kitchen staff anticipate service windows, ensures compliance tracking accuracy, and builds priority status with your provider during peak demand periods.
Choosing a Grease Trap Service Provider in Los Angeles
Los Angeles supports dozens of grease trap service companies, from regional chains to local independents. Verify that any provider holds current California contractor licenses, carries liability insurance (minimum $1 million coverage), and operates permitted waste hauling vehicles. LA County requires all FOG waste to go to approved receiving facilities — unlicensed haulers who dump illegally expose your business to joint liability and fines up to $25,000.
Compare service contracts carefully before committing. Flat-rate monthly agreements provide budget predictability, while per-visit pricing offers flexibility for seasonal operations. Most providers require 12-month contracts with automatic renewal clauses. Watch for hidden fees: fuel surcharges, weekend service premiums, extra charges for disposal of excessive solids, and penalties for service access delays. Get everything in writing, including guaranteed response times for emergency calls.
Local reputation matters more than national brand recognition in the grease trap industry. Check recent reviews on Google and Yelp, focusing on responsiveness, service quality, and billing accuracy. Ask potential providers for references from restaurants similar to yours in size and cuisine type — a company that excels at small café service may lack equipment for large-scale hotel operations. To explore verified providers across California, browse grease trap services in California.
Request digital service manifests via email or text immediately after each cleaning. Cloud-based records prevent documentation loss and allow instant access during surprise health inspections. Many modern providers offer customer portals for real-time service history tracking.
Additional Costs and Considerations
Beyond standard pump-out fees, budget for ancillary grease management costs. Enzyme treatments and bacterial additives help break down FOG between cleanings but aren't substitutes for professional service — LA County explicitly prohibits reducing cleaning frequency based on additive use. These products cost $40–$120 per month and work best as supplements to proper cleaning schedules, not replacements.
Trap repairs and replacements represent significant unplanned expenses. Baffles, gaskets, and covers wear out over 5–10 years depending on trap quality and maintenance history. Minor repairs (gasket replacement, cover resealing) run $200–$500, while full trap replacement starts at $3,000 for small units and exceeds $15,000 for large in-ground interceptors. Regular professional service extends trap lifespan by catching issues early.
Some LA restaurants add grease recovery services to monetize waste cooking oil. Providers pay $0.30–$0.60 per gallon for used fryer oil suitable for biodiesel production. While this doesn't offset trap service costs, it creates a small revenue stream that can cover 10–20% of monthly grease management expenses for high-volume frying operations.
Frequently Asked Questions
How often do grease traps need to be cleaned in Los Angeles?
Most Los Angeles restaurants require grease trap cleaning every 2–4 weeks to comply with LA County's 25% capacity rule. High-volume kitchens with heavy frying operations need bi-weekly service, while lower-volume establishments may extend to monthly cleanings. Your specific frequency depends on trap size, menu type, and kitchen volume.
What is the average cost of grease trap cleaning in LA?
The average cost ranges from $150 to $800 per cleaning depending on trap capacity. A typical 500-gallon trap at a mid-sized restaurant costs $350–$600 per monthly service visit. Monthly service contracts provide better value than per-visit pricing for restaurants requiring regular cleanings to maintain compliance.
Can I clean my own grease trap to save money?
LA County regulations don't prohibit self-cleaning, but professional service is highly recommended. You must properly dispose of FOG waste at approved facilities, maintain detailed records, and ensure the trap meets the 25% capacity threshold. Most restaurants lack proper equipment and disposal access, making professional service more cost-effective and compliant.
What happens if I miss a grease trap cleaning?
Missing scheduled cleanings risks FOG ordinance violations during health inspections, starting with $1,000 fines. Overfilled traps also cause sewage backups, kitchen flooding, and potential health permit suspension. Maintain consistent service schedules and keep all documentation accessible to avoid penalties and operational disruptions.
Do grease trap service costs vary by LA neighborhood?
Yes, providers charge 10–15% more for downtown LA, West Hollywood, and other high-density areas due to parking challenges and restricted access. Outlying areas like the San Fernando Valley or South Bay may have lower base rates but possible fuel surcharges. Overall cost differences typically amount to $20–$40 per visit across metro LA.
