For restaurant owners and facility managers in California, maintaining a clean and compliant grease trap or interceptor is a critical operational and legal responsibility.

California enforces strict, multi-layered regulations at the state and local levels to protect its wastewater infrastructure. Navigating these rules-which dictate cleaning frequency, maintenance standards, and record-keeping-is essential for avoiding significant fines and ensuring your business runs smoothly.

Understanding California's Grease Trap Regulations
California's approach to grease management is governed by a combination of the state's Plumbing Code and stringent local ordinances from city wastewater authorities. The goal is uniform: to minimize FOG discharge into public sewers.
The Core 25% Rule The fundamental standard statewide is known as the "25% rule." A grease interceptor must be cleaned when the combined volume of accumulated FOG and settled solids reaches 25% of the total liquid depth of the trap 1 2 3. Exceeding this level is a violation and requires immediate servicing. This rule emphasizes proactive, volume-based maintenance rather than relying solely on a fixed calendar schedule.
Mandated Minimum Cleaning Frequency While the 25% rule is primary, most local jurisdictions also set a mandatory maximum interval between cleanings. A common requirement across many California cities is that grease traps must be serviced at least every six months, regardless of accumulation 1 4 5. However, for high-volume kitchens-such as busy diners, fast-food establishments, or restaurants serving cuisine with high grease content-actual needed frequency can be much higher, often ranging from weekly to monthly 1 6.
Local Ordinance Compliance It is crucial to consult your specific city's municipal code. Regulations in Los Angeles, San Francisco, San Diego, and smaller cities like Fullerton or Claremont can have unique provisions regarding interceptor design, capacity, and inspection protocols 2 4. Always adhere to the strictest applicable standard, whether local or state.
Permitting, Record-Keeping, and Service Requirements
Proper administration is as important as the physical cleaning. California law sets clear expectations for documentation and the use of qualified professionals.
Permits and Approvals Installation or modification of a grease interceptor typically requires a permit from your local building or plumbing department. Furthermore, your facility is often subject to approval and ongoing oversight by the local wastewater authority (e.g., the city's Public Works or Sanitation District) 5 7. They may require an initial inspection to ensure proper installation and accessibility.
Essential Record-Keeping Maintaining detailed service records is non-negotiable. For every cleaning, you must obtain and keep a manifest or invoice from the service provider. This document should include:
- The date of service.
- The volume of waste removed (in gallons).
- The name and license number of the hauler.
- The disposal location (the approved rendering plant or wastewater facility). These records must be kept on-site for a minimum of three years and be readily available for annual or random inspections by city officials 1 5.
Using Licensed and Approved Haulers California regulations require that grease trap waste be pumped and transported by a licensed liquid waste hauler 1 7. These professionals are authorized to dispose of the collected FOG at approved facilities, such as rendering plants or wastewater treatment centers equipped to handle it. Using an unlicensed service can result in violations for your business.
Ensuring Accessibility The law mandates that grease interceptors be easily accessible for inspection, maintenance, and pumping 8. They should not be located in food preparation areas unless specifically approved, and clear access paths must be maintained.

Cost of Grease Trap Cleaning Services in California
The price for grease interceptor maintenance varies significantly based on several factors. Understanding these can help you budget effectively and evaluate service quotes.
Typical Price Ranges
- Small Indoor Grease Traps: Commonly found under sinks, these typically cost between $120 and $385 per service 9 10.
- Large Outdoor Grease Interceptors: These in-ground or concrete vault units service high-volume kitchens. Pumping costs for these larger systems range from $325 to over $1,040 per service 9 11.
Key Factors Influencing Cost
- Size and Type: Larger capacity interceptors naturally cost more to pump due to increased labor, time, and disposal volume.
- Service Frequency: Establishing a regular service contract (e.g., monthly or quarterly) can often reduce the per-service cost compared to one-time emergency calls 11 10.
- Location and Access: Traps that are difficult to access (e.g., in a cramped basement or a congested alley) may incur additional charges.
- Bundled Services: Many providers offer discounts if you bundle grease trap cleaning with other services like used cooking oil collection or drain line jetting.
Best Practices for Proactive Grease Management
Beyond compliance, effective grease management protects your plumbing and reduces long-term costs.
- Train Kitchen Staff: Educate employees on proper scrap practices-scraping food waste into trash bins before washing dishes-to minimize solids entering the trap.
- Avoid Additives: Do not use emulsifying agents or "grease digesting" chemicals that break up FOG. These simply pass the grease downstream where it can re-solidify and cause blockages in city lines, which you can be held responsible for 11.
- Schedule Regular Inspections: Visually check your indoor trap regularly for accumulation. For larger interceptors, work with your service provider to schedule inspections between pumpings.
- Establish a Service Contract: A contract with a reputable, licensed provider ensures regular service, helps you maintain compliance, and can lock in predictable pricing.
Consequences of Non-Compliance
Failing to maintain your grease trap properly can lead to serious repercussions:
- Substantial Fines: Wastewater authorities can levy significant fines for violations, often starting at hundreds of dollars and increasing for repeat offenses.
- Sewer Blockages and Backups: A neglected trap can cause backups in your own kitchen or the public sewer, leading to business interruption, costly cleanup, and potential liability.
- Permit Suspension: In severe cases, the city can suspend your operating or wastewater discharge permit until violations are corrected.
