Grease Trap Violation Fines by City
What FOG violations can cost in 50 US and 8 Canadian cities. Figures marked High have been checked against a specific ordinance; the rest are being re-verified.
What FOG Violations Actually Cost
Grease trap non-compliance fines vary dramatically by city — from a few hundred dollars for a first violation in smaller markets to $10,000 per day in New York City or, in Toronto, up to $50,000 on a first conviction for an individual and $100,000 for a corporation. The difference comes down to how seriously each municipality treats FOG enforcement. Cities with active pretreatment programs and dedicated FOG inspectors issue fines as a matter of routine. Cities with framework-only programs may have fine schedules on the books but rarely enforce them administratively.
What most restaurant owners don't realize is that fines are rarely the worst consequence of non-compliance. A grease trap overflow that reaches the municipal sewer system can trigger a Sanitary Sewer Overflow (SSO) event — and SSOs carry federal Clean Water Act liability that dwarfs any local fine schedule. The cities that fine hardest are the same ones most likely to escalate to SSO enforcement. If your city shows "Active" enforcement below, take the fine schedule seriously.
This table is being re-verified against primary sources. Confidence reflects verification status, not severity: High means a specific ordinance or published fee schedule was opened and the citation appears on the row — click any row to read it. Medium and Low mean the figure has not yet been confirmed against a primary source and should be treated as indicative only. Most municipalities publish no FOG-specific fine schedule at all; where that is so, the figure shown is the maximum the sewer-use ordinance allows, not a typical first-violation fine.

About this data: Originally compiled in Q1 2026 and currently being re-verified against primary sources, city by city. High = checked against a named ordinance or published fee schedule, with the citation shown on the row. Medium and Low = not yet confirmed against a primary source; treat as indicative only. Fine schedules change, and many authorities publish no FOG-specific amount at all — always confirm with your local sewer authority before making compliance decisions.

Active vs. Framework Enforcement — What the Difference Means
An "Active enforcement" designation means the city has a dedicated FOG pretreatment program with inspectors who conduct regular compliance checks, issue notices of violation, and administratively levy fines without requiring a court proceeding. These are the markets where non-compliance carries real financial risk on a routine basis. Dallas, Nashville, New York, Los Angeles, and most major Canadian cities fall into this category.
"Framework only" means the city has FOG ordinances and fine schedules on paper, but enforcement is complaint-driven or reactive rather than proactive. Fines exist but are rarely issued for first offenses — inspectors typically respond to overflows or complaints rather than conducting routine compliance audits. This doesn't mean you can ignore compliance in these markets; it means the trigger for enforcement is usually a visible problem rather than a missed cleaning cycle.
FOG Fines — Common Questions
Yes, in active enforcement cities. FOG violations are typically issued for non-compliance with the cleaning schedule — not just for overflows. If your city requires cleaning every 90 days and an inspector finds your trap hasn't been serviced in 6 months, that's a violation regardless of whether anything overflowed. Some cities specifically cite capacity violations: if your trap is found to be more than 25% full of grease and solids during an inspection, that's a citable condition in markets with the 25% rule. Maintain your cleaning records and keep service manifests on file.
Often, but not universally. Many programs use a tiered structure where a first violation draws a warning or lower fine and repeat violations escalate, and chronic non-compliance can lead to permit suspension or mandatory equipment upgrades. Others publish a single specified penalty per offence with no escalation at all — Calgary is one. Check your own city’s ordinance rather than assuming escalation applies."Repeat" column in the table above shows the escalated fine schedule. In the most aggressive markets like NYC and Toronto, repeat violations can trigger daily fines that accumulate faster than most restaurants can respond. First offense leniency disappears after the first Notice of Violation is on record.
A FOG fine is an administrative penalty for non-compliance with the FOG ordinance — it's a citation, like a traffic ticket. A sewer surcharge is an additional fee added to your utility bill when discharge from your establishment exceeds permitted concentrations of fats, oils, and grease. Some cities use one, some use both. Surcharges are typically triggered by sampling results and show up on your water bill; fines are issued by inspectors and require a separate payment process. Both can run simultaneously if a discharge event triggers both the ordinance violation and the pretreatment concentration limit.
