Los Angeles Grease Trap & Interceptor Requirements
Los Angeles restaurants must maintain compliant grease traps and interceptors under strict Department of Environmental Affairs (LADEA) and Los Angeles Department of Health (LAPH) regulations. Failure to maintain proper grease trap systems can result in significant fines, closure orders, and environmental violations. Understanding local requirements is essential for restaurant operators and food service managers.
LA Grease Trap Sizing & Installation Standards
Los Angeles requires grease traps and grease interceptors to be sized according to flow rates and fixture counts under the California Plumbing Code and LAPH guidelines. All food service establishments must install traps with a capacity of at least 50% of the hourly drainage flow from kitchen fixtures. Grease interceptors must be accessible for inspection and cleaning, typically located outside the building or in designated areas. Installation must comply with LADEA permits, and professional licensed plumbers are required for all work. The city requires interceptors to be properly vented and equipped with baffles to effectively separate grease from wastewater.
Inspection, Maintenance & Pumping Requirements
LAPH and LADEA conduct unannounced inspections of restaurant grease trap systems as part of routine health and environmental compliance audits. Most LA establishments must pump and clean grease traps every 30–90 days, depending on usage volume and local regulations; high-volume establishments may require more frequent service. Owners must maintain detailed maintenance logs and retain documentation for at least three years, including service dates, amounts removed, and contractor information. Violations for neglected or improperly maintained traps are documented during health inspections and reported to the city. Professional pumping and disposal must be handled by licensed waste management contractors.
LA Fines, Violations & Enforcement
The City of Los Angeles enforces grease trap compliance through LAPH health inspections and LADEA environmental violations, with fines ranging from hundreds to thousands of dollars per violation. Improper grease disposal—including dumping grease into municipal sewer systems—can trigger separate fines from LA's Bureau of Sanitation. Repeated violations may result in closure orders, lost operating permits, or mandatory corrective action plans. Restaurants cited for grease-related violations during routine inspections must provide proof of remediation and ongoing compliance. Environmental discharge violations related to grease and FOG (fats, oils, grease) can also trigger state-level penalties through the Regional Water Quality Control Board.
