Florida Fire Code Requirements for Commercial Kitchen Hoods

Florida enforces commercial kitchen hood requirements through the Florida Fire Prevention Code, which adopts NFPA 96 as the governing rule for hood and exhaust cleaning. NFPA 96 is the national Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations. In practice that means your local fire marshal inspects your system against it: how often it is cleaned, how clean it gets, who cleans it, and how the work is documented. Here in St. Lucie County, that authority is the St. Lucie County Fire District. Below is what the code requires and what inspectors here expect to see.

Cleaning Frequency Is Set by How You Cook

The code does not set one schedule for everyone. It ties the minimum inspection-and-cleaning interval to your cooking volume and fuel type, and your authority having jurisdiction can require more frequent service based on what they find. There are four tiers.

• Monthly: solid-fuel cooking (wood, charcoal, pellets) and high-volume operations. Solid fuel carries the strictest interval and the highest risk.
• Quarterly: high-volume, 24-hour, charbroiler, and wok cooking that runs hot most of the day.
• Semi-annually: moderate-volume sit-down restaurants with a typical lunch-and-dinner service.
• Annually: low-volume and seasonal kitchens such as churches, day cares, and senior centers.

The Grease-Depth Triggers

Beyond the calendar, the standard sets measurable grease-depth thresholds (§12.6.1.1) that require cleaning regardless of the schedule. A certified technician measures buildup with a grease gauge against these limits.

• 0.002 inch: a paper-thin layer on hoods, filters, fans, and ducts. This is the strictest trigger and it governs the primary grease path.
• 0.078 inch: roughly two stacked dimes, on other interior surfaces.
• 0.125 inch: one-eighth of an inch, on fan housings.

The most restrictive threshold governs. Because the 0.002-inch limit applies to the primary grease path, that is the number that usually decides whether your system is due.

What a Compliant Cleaning Must Cover

NFPA 96 requires the system be cleaned by a properly trained, qualified, and certified person acceptable to the AHJ, and that the work meet the bare-metal standard. That means every accessible surface scraped and washed to the metal. The code also sets specific access and documentation requirements.

• Ductwork must have adequate access panels; panels are restored to operational condition after cleaning and tagged with the company name and date (§12.6.9-10)
• Rooftop fans need a hinge kit or a minimum 3"x5" (or 4" diameter) access opening so they can be cleaned and inspected (§8.1.6.3)
• Rooftop grease containment is required around the exhaust fan to protect the roof
• A dated service sticker goes on the hood after cleaning (§12.6.13), and a written report documents any areas that could not be reached (§12.6.14-15)

Important note: under NFPA 96 §4.1.5, responsibility for keeping the system compliant rests ultimately with the system owner unless transferred in writing. The restaurant operator is on the hook, not the cleaner alone. That is why keeping documented, certified cleanings on file protects you directly.

What St. Lucie County Inspectors Expect

Fire-prevention authority across Port St. Lucie and Fort Pierce is the St. Lucie County Fire District, an independent countywide special district. One Fire Prevention Bureau is the AHJ for the whole area. Florida also requires kitchen fire-suppression systems to be UL-300 listed, and inspectors here expect to see a dated professional-cleaning certificate posted on the hood, ready at inspection. A consistent, documented cleaning schedule is what clears a visit without trouble.

Please note: requirements vary by jurisdiction. If your kitchen is in Martin County (Stuart, Palm City, Jensen Beach, Hobe Sound) or Indian River County (Vero Beach), a different fire-prevention office is your AHJ, and some counties inspect every commercial occupancy annually. Always confirm the specific requirements with your local fire marshal. Ask us if you are unsure which authority covers your address.

Meeting the Florida fire code comes down to a documented, bare-metal cleaning on the right interval, done by a certified technician. Our commercial kitchen hood cleaning is built around the national fire code for kitchen exhaust and delivers the sticker, photos, and report your inspector looks for.
