FOG / Grease Trap Service Records — City of Chicago
Chicago requires grease traps cleaned when 25% full (typically every 30–90 days), with maintenance records kept at least three years.
What it is. Recurring cleaning of the grease trap/interceptor with retained records, under the City Sewer Use Ordinance.
Who issues/enforces it. City of Chicago — Department of Water Management (City layer).
When you need it. Ongoing. Clean when FOG and solids occupy 25% of the trap's capacity; pumping frequency is typically every 30–90 days depending on volume.
How to comply. Use a licensed hauler; keep detailed maintenance records (dates, hauler, volume removed, disposal, repairs, signatures) for at least three years.
Cadence. Typically every 30–90 days (or when 25% full).
What SpoonSeal tracks. The document(s) you upload for this requirement, with automatic renewal/expiration tracking (Current, Due Soon, Expired). Where the city publishes health-inspection results (e.g., NYC and Chicago), SpoonSeal syncs them automatically; elsewhere they can be added manually.
