Grease Trap Cleaning in Portland, OR: Cost, Rules & Top Companies (2026)
Running a commercial kitchen in Portland? Staying on top of grease trap cleaning keeps you out of a sewer backup and compliant with Oregon's FOG rules. Here's what it costs in Portland, 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 Portland
Portland 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 size | Typical 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 Portland
Clean at 25% of FOG-and-solids capacity (high-efficiency units up to 75%); BES sets frequency by establishment type, size, and flow (under Portland City Code 17.34; Administrative Rule ENB-4.26). 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.
