Grease Trap Cleaning in Boise, ID: Cost, Rules & Top Companies (2026)
Running a commercial kitchen in Boise? Staying on top of grease trap cleaning keeps you out of a sewer backup and compliant with Idaho's FOG rules. Here's what it costs in Boise, 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 Boise

| Medium trap (50–500 gal) | $150 – $475 |
| Large interceptor (500–1,500 gal) | $400 – $1,200 |

How Often You Must Clean It in Boise
When FOG and solids reach 25% of capacity; typically at least every 90 days (under Boise City Code Chapter 2 (Sewer Use); §11-05-07 (Violations)). 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.
