# Hillsborough County Grease Trap Requirements (90-Day) > Hillsborough County grease trap requirements: service at least every 90 days, never over 25% full, 12-month records, and self-cleaning only under 50 lb. URL: https://greasetrapcleaningtampa.com/guide/hillsborough-county-grease-trap-rules/ Learn # What Are Hillsborough County's Grease Trap Requirements? The county rule for Brandon, Riverview, Carrollwood, Town 'n' Country and the rest of unincorporated Hillsborough, and how it differs from the City of Tampa's. Updated November 14, 2026 [Grease Trap Cleaning Tampa](https://greasetrapcleaningtampa.com/) follows Hillsborough County's grease rule for unincorporated areas such as Brandon and Riverview. Every grease trap and interceptor must be serviced at least once every 90 days, and its grease and solids may never exceed 25% of wetted volume. Invoices or manifests stay on site for 12 months. ## Who it covers Hillsborough County’s Grease Management Program applies to food service establishments in **unincorporated** Hillsborough County that discharge to the County’s sewer system. That includes Brandon, Riverview, Valrico, Seffner, Carrollwood and Town ‘n’ Country. It’s run by County Public Utilities under County Code Chapter 120 (Ordinance 06-31, Article VII). The City of Tampa and Temple Terrace have their own grease ordinances. Other incorporated cities should check with their own utility. ## The 90-day / 25% rule From the County’s grease management FAQ: - **All grease interceptors and grease traps** must be serviced **at least once every 90 days**. - At **no time** may the device’s contents exceed **25% of its wetted volume**. - The 90-day minimum doesn’t override a stricter schedule you’ve already been set. - **Alternate schedules** are reviewed case by case. You must show the unit can go longer without service and still meet the 25% standard continuously. The 90 days is a ceiling. A busy kitchen can hit 25% in a month, and the 25% limit is the one inspectors measure. ## Self-cleaning Small under-the-counter traps with **less than 50 pounds** of grease retention capacity may be cleaned by your own staff, with the removed material going out with your solid waste. Everything larger needs a hauler registered with the County. The County registers haulers separately from the City of Tampa. See [can I clean my own grease trap?](https://greasetrapcleaningtampa.com/guide/can-i-clean-my-own-grease-trap/) ## Records Keep a copy of the **invoice or manifest** for every service, showing the date and the volume removed, on site or available for at least **12 months**. Florida law separately requires you to keep each signed hauler manifest for a year. See [grease trap records and manifests](https://greasetrapcleaningtampa.com/guide/grease-trap-records-manifests-florida/). ## Inspections County staff carry out **scheduled and unannounced** inspections of food service establishments, checking installation, operation, maintenance and records. They may also take wastewater samples to check your discharge.

The City of Tampa uses condition-based triggers with no fixed day count, and Temple Terrace runs its own grease ordinance. ### Can I clean my own grease trap in Hillsborough County? Only small under-counter traps with less than 50 pounds of grease capacity, with the waste going out as solid waste. Larger traps and all interceptors need a County-registered hauler. ### Can I get a longer pumping schedule than 90 days? Possibly. The County reviews alternate schedules individually, and you must show the unit can go longer without service while staying under 25% the whole time. ## More guides - [How Do You Choose a Grease Trap Company?Eight questions that separate a hauler who keeps you compliant from one who just empties the tank.](https://greasetrapcleaningtampa.com/guide/choosing-a-grease-trap-company/) - [Do Grease Trap Enzymes Replace Pumping?What additives actually do, what each local program allows, and why none of them remove the need to pump.](https://greasetrapcleaningtampa.com/guide/grease-trap-enzymes-vs-pumping/) - [How Often Should a Grease Trap Be Cleaned in Tampa Bay?Nine rule sets in one metro.
