Grease Trap Cleaning Frequency Guide for Florida

Florida's Chapter 62-705 requires all food service establishments to maintain their grease traps and interceptors on a schedule that prevents grease waste from entering the public sewer system. While the state law does not prescribe a single statewide cleaning interval, most Florida counties require cleaning every 30 to 90 days depending on your trap type, size, and the volume of grease your operation generates. The safest rule of thumb is the 25% rule: clean your trap before accumulated grease and solids reach 25% of the trap's total capacity.

Getting your cleaning frequency right protects you from costly violations, prevents emergency overflows, and keeps your kitchen running smoothly. This guide covers state requirements, county-specific rules across Florida, recommended frequency by establishment type, and the factors that should inform your schedule.

State Requirements Under Chapter 62-705

Chapter 62-705 F.A.C. (Florida Administrative Code) establishes the regulatory framework for grease waste removal and disposal in Florida. The regulation, administered by the Florida Department of Environmental Protection (DEP), requires:

• All grease waste must be removed by a DEP-licensed hauler
• Every pump-out must be documented on DEP Form 62-705.300(3)
• Grease traps and interceptors must be maintained in proper working condition
• Accumulated grease waste must not be allowed to pass through to the sewer system

The state regulation intentionally defers specific cleaning frequency requirements to local jurisdictions (counties and municipalities), recognizing that the appropriate interval varies by trap size, establishment type, and local sewer infrastructure capacity. This means your cleaning schedule is primarily determined by your county's FOG (fats, oils, and grease) ordinance.

However, the state's requirement that grease not pass through to the sewer effectively means you cannot let your trap go indefinitely between cleanings. If an inspection reveals that your trap has failed — meaning grease is passing through the outlet — you are in violation regardless of whether you met a specific time interval.

County-Specific Frequency Requirements

Florida's 67 counties each have their own FOG control programs with specific cleaning requirements. Here are the documented requirements for Florida's major counties:

Miami-Dade County

Enforcement agency: DERM (Department of Environmental Resources Management) Program: FOG Control Program

Miami-Dade uses the 25% capacity rule rather than a fixed time interval. Your grease trap or interceptor must be cleaned before accumulated grease and solids reach 25% of the trap's total liquid capacity.

What this means in practice:

• A high-volume restaurant with a 1,000-gallon interceptor might need monthly cleaning
• A lower-volume establishment might go 60 to 90 days
• Interior traps (20-100 gallons) typically need weekly to biweekly cleaning under this rule

The 25% rule is actually the gold standard and is recommended statewide as a best practice, even in counties that use fixed intervals. Find Miami-Dade providers.

Pinellas County

Enforcement agency: Pinellas County Utilities Program: Commercial Grease Management Program

Pinellas County has some of Florida's most stringent requirements:

• Grease interceptors: Monthly cleaning required
• Interior grease traps: Per permit — typically weekly to biweekly
• Automatic grease removal devices: Per manufacturer specifications, with quarterly professional inspection

Monthly interceptor cleaning is more frequent than most Florida counties require. Pinellas restaurants should budget accordingly — see our cost guide for Pinellas County pricing. Find Pinellas providers.

Hillsborough County

Enforcement agency: Hillsborough County Public Utilities Program: Grease Management Program

• Grease interceptors: Every 90 days (quarterly) minimum
• Interior grease traps: More frequent cleaning may be required based on inspection
• Interceptors serving multiple tenants: May require monthly cleaning

Hillsborough's 90-day interval is the most common standard across Florida and is a reasonable baseline for most establishments. Find Hillsborough providers.

Sarasota County

Enforcement agency: Sarasota County Utilities Program: FOG Program (established 2020)

Sarasota County distinguishes between trap types:

• Interior grease traps: Every 30 days
• Underground grease interceptors: Every 90 days
• More frequent cleaning may be required if inspections show excessive buildup

The 30-day interior trap requirement is stricter than many counties and reflects the rapid accumulation rate of small under-sink units. Find Sarasota providers.

Orange County

Enforcement agency: Orange County Utilities Program: FOG Control Program

• Frequency: Per permit conditions — typically 90 days for interceptors
• Interior traps: Per permit, typically monthly or more frequent
• Variance: Available for establishments that demonstrate consistent low accumulation

Orange County's permit-based approach allows some flexibility, but the default expectation is quarterly interceptor cleaning. Find Orange County providers.

Duval County (Jacksonville)

Enforcement agency: JEA (Jacksonville Electric Authority) Program: Preferred Hauler Program

• Frequency: Per permit — typically 90 days for interceptors
• JEA preferred haulers are pre-vetted for compliance, making selection easier
• Interior traps: Per permit conditions

JEA's Preferred Hauler Program is unique in Florida — haulers on the list have been verified for licensing, insurance, and disposal compliance. Using a preferred hauler simplifies your compliance burden. Find Duval providers.

Palm Beach County

Enforcement agency: SWA (Solid Waste Authority) and local utilities Program: Grease Waste Program

• Frequency: Per permit — typically quarterly for interceptors
• Interior traps: Monthly or per permit
• Manifests required for every service visit

Find Palm Beach providers.

Broward County

Enforcement agency: County and municipal utilities (varies by city) Program: FOG Control Programs (city-level)

• Frequency: Varies by municipality, typically quarterly for interceptors
• Fort Lauderdale, Hollywood, Pompano Beach each have their own specific requirements
• Check with your local utility for exact requirements

Find Broward providers.

Lee County

Enforcement agency: Lee County Utilities Program: FOG Ordinance

• Frequency: Per permit — typically quarterly for interceptors
• More frequent cleaning for high-volume establishments
• Interior traps: Per permit conditions

Find Lee County providers.

Volusia County

Enforcement agency: Volusia County Utilities Program: FOG Program

• Frequency: Per permit — typically quarterly
• Seasonal adjustments may be required during peak tourist season (higher restaurant volume in beach communities)

Find Volusia County providers.

Frequency by Establishment Type

Your establishment type significantly affects how quickly grease accumulates and, therefore, how often you need to clean. Here are recommended frequencies based on typical grease production:

High-Volume Restaurants (Full-Service, Fried Food Heavy)

• Interior traps: Weekly to biweekly
• Underground interceptors: Monthly to every 45 days
• Examples: Fried chicken restaurants, seafood restaurants, Chinese/Asian restaurants, burger joints, 24-hour diners

These establishments produce the highest volumes of FOG due to deep fryers, wok cooking, and high meal counts. In Miami-Dade, they frequently trigger the 25% rule within 30 days.

Average-Volume Restaurants (Full-Service, Mixed Menu)

• Interior traps: Biweekly to monthly
• Underground interceptors: Every 60 to 90 days
• Examples: Casual dining chains, Italian restaurants, steakhouses, Mexican restaurants, pizza restaurants

These are the "typical" restaurant and represent the majority of food service establishments in Florida. Quarterly interceptor cleaning (90 days) is usually sufficient if kitchen practices are good.

Low-Volume Food Service

• Interior traps: Monthly
• Underground interceptors: Quarterly (90 days)
• Examples: Bakeries, delis, sandwich shops, coffee shops with limited food prep, corporate cafeterias with light cooking

These establishments produce less FOG but still require regular maintenance. Don't assume that low volume means you can skip cleanings — even a small amount of grease accumulates over time and can cause blockages.

School and Institutional Cafeterias

• Interior traps: Monthly during the school year, less frequent during breaks
• Underground interceptors: Quarterly, with possible variance during summer
• Examples: K-12 school kitchens, university dining halls, hospital cafeterias, nursing home kitchens

Institutional kitchens often have predictable, seasonal patterns. Some counties allow adjusted schedules during extended closures (summer break, holiday breaks) as long as you resume regular cleaning when operations restart.

Hotels and Resorts

• Interior traps: Weekly to biweekly (multiple food outlets)
• Underground interceptors: Monthly to every 60 days
• Examples: Full-service resort restaurants, hotel banquet kitchens, room service kitchens

Hotels and resorts often have multiple grease traps serving different kitchen areas. Each trap should be evaluated individually — the main restaurant kitchen trap will fill faster than the poolside bar's trap.

Catering Companies

• Interior traps: Biweekly to monthly
• Underground interceptors: Monthly to quarterly, depending on event volume
• Examples: Off-premise catering, commissary kitchens, event venues

Catering volumes fluctuate with the event calendar. During peak season (November through April in Florida), you may need more frequent cleaning.

Food Trucks

• Interior traps: Weekly to biweekly (small traps fill quickly)
• Examples: Mobile food vendors with on-board grease management systems

Food trucks have very small grease traps (typically 5-20 gallons) that fill rapidly during service. Frequent cleaning is essential to prevent backups in the confined space of a food truck kitchen.

Factors That Affect Your Cleaning Frequency

Beyond establishment type and county requirements, several operational factors influence how often your trap needs cleaning:

1. Menu Type

The type of food you prepare is the strongest predictor of grease production:

• Deep-fried foods: Highest grease production. Fryer oil, batter drippings, and grease-laden wash water fill traps rapidly.
• Grilled and sauteed foods: Moderate grease production. Pan drippings and cooking oils contribute, but less than deep frying.
• Baked goods: Lower grease production, but butter, shortening, and oil-based recipes still generate FOG.
• Cold prep (salads, sandwiches): Minimal grease production, primarily from dressings and mayo.

A restaurant that deep-fries 80% of its menu will need cleaning two to three times more frequently than one that focuses on grilled items.

2. Daily Meal Count

More meals served equals more grease produced. A restaurant serving 500 covers per day will fill its trap much faster than one serving 100. If you significantly increase your daily volume (adding a lunch service, extending hours, or adding catering), reassess your cleaning frequency.

3. Trap Size

Larger traps accumulate grease more slowly relative to their capacity, allowing longer intervals between cleanings. A 2,000-gallon interceptor serving the same restaurant that would overflow a 500-gallon interceptor in 30 days might go 90 to 120 days between cleanings.

However, a larger trap does not eliminate the need for regular cleaning. Even a large interceptor that is cleaned infrequently will develop hardened grease deposits that are more difficult and expensive to remove.

4. Kitchen Practices

Good kitchen practices can extend your cleaning interval by 25% to 50%:

• Scrape before washing: Scraping plates and pans into the trash before putting them in the wash significantly reduces grease entering the drain.
• Use drain strainers: Metal mesh strainers in floor drains and sink drains catch food solids before they reach the trap.
• Separate used cooking oil: Collect fryer oil and cooking grease in a separate container for recycling, rather than pouring it down the drain.
• Cool grease before disposing: Let pans cool so grease solidifies, then scrape it into the trash.
• Staff training: Regular training on proper waste handling makes a measurable difference.

5. Seasonal Volume

Many Florida restaurants experience significant seasonal volume fluctuations:

• Peak season (November - April): Snowbird and tourist traffic can double or triple daily covers in popular areas like Naples, Sarasota, and the Keys.
• Off season (May - October): Reduced traffic may allow extended cleaning intervals.

Adjust your cleaning schedule with the seasons. Don't keep a summer schedule during peak winter season.

6. Number of Connected Fixtures

A trap that receives waste from multiple sinks, dishwashers, and floor drains fills faster than one connected to a single fixture. If you remodel your kitchen and add new drain connections to your existing trap, you may need to increase your cleaning frequency.

Consequences of Infrequent Cleaning

Skipping or delaying grease trap cleanings is a false economy. The consequences compound quickly:

Immediate Consequences

• Grease bypass: When the trap exceeds capacity, grease passes through to the sewer system. This triggers violations from your local utility and potentially the DEP.
• Kitchen backups: A full trap causes slow drains, standing water in sinks, and eventually sewage backups into your kitchen. This can force you to close during service hours.
• Odors: Accumulated grease waste produces hydrogen sulfide and other foul-smelling gases that permeate your kitchen and, in severe cases, your dining room.

Regulatory Consequences

• FOG inspection failures: County inspectors will cite you for exceeding the 25% capacity threshold or missing required cleaning intervals.
• Fines: $100 to $5,000 per violation under Chapter 62-705, plus potential county-level fines.
• Increased inspection frequency: Failed inspections often trigger more frequent inspections, creating an ongoing compliance burden.
• Health department issues: Grease overflow and sewage backups can trigger health department violations, jeopardizing your food service license.

Financial Consequences

• Emergency cleaning costs: An emergency pump-out costs 50% to 100% more than a scheduled cleaning. See our cost guide for pricing details.
• Plumbing repairs: Grease-clogged lines may require hydro jetting ($200-$500) or manual snaking.
• Business interruption: A sewage backup during dinner service can cost thousands in lost revenue, plus cleanup costs.
• Trap damage: Hardened grease deposits corrode baffles and trap walls, potentially requiring expensive repairs or replacement ($5,000-$15,000 for an underground interceptor).

Creating Your Cleaning Schedule

Follow these steps to establish the right cleaning frequency for your establishment:

Step 1: Know Your County's Minimum Requirement

Check your county's FOG ordinance for the mandated minimum cleaning interval. If your county is listed above, start there. If not, contact your county utilities department or check our county directory for information.

Step 2: Identify Your Baseline

Start with your county's minimum requirement as a baseline. If your county requires quarterly cleaning, begin with quarterly service.

Step 3: Monitor and Adjust

After the first two to three cleaning cycles, have your hauler measure the grease accumulation level before pumping. If the trap is consistently above 25% capacity at the time of service, increase your frequency. If it is consistently well below 25%, you may be able to extend the interval (as long as you meet your county's minimum).

Step 4: Document Everything

Keep records of every cleaning, including the date, the measured grease level, and the volume removed. This data helps you optimize your schedule over time and demonstrates diligence during inspections.

Step 5: Review Seasonally

Reassess your schedule twice per year — once before peak season and once after. Adjust frequency to match your actual volume.

Frequently Asked Questions

How often does Florida law require grease trap cleaning?

Florida's Chapter 62-705 does not specify a single statewide cleaning interval. Instead, it requires that grease traps be maintained to prevent grease from passing through to the sewer system. Specific cleaning frequencies are set by county FOG ordinances, ranging from monthly (Pinellas County interceptors) to quarterly (Hillsborough, most other counties). The 25% capacity rule used in Miami-Dade is the recommended best practice statewide.

What happens if I miss a scheduled grease trap cleaning?

Missing a scheduled cleaning puts you at risk of exceeding your trap's capacity, which can cause grease bypass (a violation), kitchen backups, and foul odors. If an inspector finds your trap above the allowed capacity or past its required cleaning date, you face fines of $100 to $5,000 under Chapter 62-705 and potentially additional county-level penalties.

Can I clean my grease trap myself between professional cleanings?

You can and should perform routine maintenance between professional pump-outs: scraping accumulated surface grease, cleaning strainer baskets, and checking for proper water levels. However, the actual removal and disposal of grease waste must be performed by a DEP-licensed hauler using proper manifests. Self-service pump-outs are not legal unless you hold a DEP Grease Waste Transporter license.

Does cleaning frequency change based on the season?

Yes. Florida restaurants in tourist-heavy areas often see 50% to 200% increases in volume during peak season (November through April). If your meal count increases significantly during these months, your grease production increases proportionally, and you should increase your cleaning frequency to match. Conversely, you may be able to reduce frequency during slower months, as long as you meet your county's minimum requirement.

How do I know if my grease trap needs cleaning sooner than scheduled?

Watch for these warning signs: slow-draining sinks, gurgling sounds from drains, foul odors near the trap or in the kitchen, visible grease accumulation on the trap surface (for accessible interior traps), and standing water around the interceptor access cover (for underground units). Any of these signs means your trap needs immediate attention — don't wait for the next scheduled cleaning.
