By the GreaseTrapFinder Editorial Team · Updated August 24, 2026 · California rules cited to official sources

Running a commercial kitchen in San Diego? Staying on top of grease trap cleaning keeps you out of a sewer backup and compliant with California's FOG rules. Here's what it costs in San Diego, how often you're required to clean, the permit and regulation basics, and the local companies that handle it.

What Grease Trap Cleaning Costs in San Diego

San Diego is in a higher-cost region — the Northeast and West Coast typically run 20–40% above the national baseline, so expect the upper end of these ranges.

Trap / interceptor sizeTypical cost per service
Small trap (under 50 gal)$115 – $240
Medium trap (50–500 gal)$150 – $475
Large interceptor (500–1,500 gal)$400 – $1,200
Large interceptor (1,500+ gal)$475 – $2,500

Typical ranges per service — your price depends on trap size, accessibility, and frequency. Recurring contracts usually run 15–30% below one-off rates. Estimate yours with the cost estimator or see the full pricing guide.

How Often You Must Clean It in San Diego

No single statewide interval. The Statewide Sanitary Sewer Systems General Order (Order 2022-0103-DWQ) requires sewer agencies to run FOG control programs, and city ordinances set the schedules — the 25% rule with a 90-day maximum interval is the dominant standard among major California cities. The industry-standard 25% rule applies either way: clean before fats, oils, and grease reach a quarter of your trap's capacity, because past that point grease passes straight through to the sewer. High-volume kitchens (fryers, BBQ, seafood) often need service more often than the minimum.
