Seattle Grease Trap Violations: What Inspectors Check

Common Grease Trap Violations in Seattle Inspections

Seattle health inspectors focus on three critical areas during grease trap assessments: maintenance frequency, documentation records, and physical condition. Common violations include grease accumulation exceeding 25% of trap depth, absence of cleaning logs, and evidence of illegal grease discharge into municipal sewers. Inspectors also cite restaurants lacking proper labeling on traps, blocked access covers, and undersized interceptors serving high-volume food preparation areas. The Seattle Municipal Code requires commercial food establishments to maintain interceptors in compliance with adopted plumbing codes, with inspectors photographing violations and cross-referencing disposal company records.

Seattle Penalty Structure and Regulatory Requirements

The Seattle Department of Construction and Inspections (SDCI) and local health department enforce violations under Washington State Administrative Code (WAC 246-215) and Seattle Municipal Code Chapter 15.47. First-time violations typically result in corrective action notices requiring compliance within 10–30 days; repeat violations trigger escalating fines of $500–$2,000 per citation. Establishments with persistent non-compliance face permit suspension or closure orders. Seattle also requires grease trap waste be disposed through licensed waste haulers; improper disposal can trigger additional enforcement from the EPA and State Department of Ecology, adding environmental violation charges separate from health department penalties.

Best Practices to Avoid Grease Trap Citations

Establish a documented maintenance schedule with professional grease trap cleaning at intervals specified by your waste hauler—typically every 30–60 days depending on volume and trap capacity. Maintain detailed records including pump-out dates, waste hauler contact information, and photographs of trap condition; inspectors specifically request this documentation during routine visits. Train kitchen staff on proper grease disposal (cooling oils before discarding, blocking drain screens, avoiding grease pours) and install visible signage at sinks. Schedule quarterly self-inspections measuring grease depth with a measuring stick and verify drain functionality; proactive maintenance prevents the 25% accumulation threshold that triggers violations during official inspections.
