NFPA 96 is the national standard for fire protection of commercial cooking operations — and in Florida it's not optional. The Florida Fire Prevention Code adopts it statewide, your local fire marshal enforces it, and your insurance carrier holds you to it. This guide covers what the standard actually requires: cleaning frequencies, who may do the work, the bare-metal benchmark, and the paperwork that keeps you open.
NFPA 96 is the National Fire Protection Association's Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations. It governs how commercial kitchen exhaust systems — hoods, grease ducts, filters, and exhaust fans — must be designed, inspected, cleaned, and maintained. On its own it's a standard; it becomes law wherever a fire code adopts it.
Florida adopts it statewide. The Florida Fire Prevention Code (FAC Chapter 69A-60) incorporates NFPA 96 by reference, which makes professional kitchen exhaust cleaning a legal requirement for every commercial kitchen in the state — from a Tampa food truck to an Orlando resort. Local fire departments (the "authority having jurisdiction," or AHJ) enforce it during inspections.
NFPA 96 sets frequency by cooking volume and fuel type — the table below is the one your fire inspector uses. Two details operators miss: the tier follows your busiest cooking style, not your average week, and any solid-fuel appliance (a wood-fired oven, a charcoal grill) pulls that system into the monthly tier regardless of everything else.
| Cooking operation | Typical examples | Required frequency |
|---|---|---|
| Solid-fuel cooking | Wood-fired ovens, charcoal, mesquite, smokers | MONTHLY |
| High-volume cooking | 24-hour kitchens, charbroiling, wok cooking | QUARTERLY |
| Moderate-volume cooking | Typical sit-down restaurants, hotel kitchens | SEMI-ANNUALLY |
| Low-volume cooking | Churches, day camps, seasonal businesses, senior centers | ANNUALLY |
These are inspection intervals at minimum — a system inspected on schedule and found grease-laden must then be cleaned. The commonly cited trigger is measurable accumulation of about 2,000 microns (~2 mm) of grease on system surfaces.
All of it — that's the point most cut-rate vendors miss. Grease-laden vapor condenses along the entire exhaust path, and NFPA 96 requires the whole path be cleaned to bare metal: canopy hood and plenum, baffle filters, every foot of grease duct (through access panels, added where missing), and the rooftop exhaust fan. A shiny canopy over a loaded duct is a failed inspection and a fire waiting for an ignition source.
NFPA 96 requires the exhaust system be inspected and cleaned by properly trained, qualified, and certified persons acceptable to the AHJ — in practice, a professional exhaust cleaning company. Your staff can (and should) wash baffle filters and wipe the canopy between services, but staff cleaning does not satisfy the code, and it produces none of the documentation your fire marshal or insurer will ask for.
After a compliant cleaning, three artifacts prove it happened — and they're exactly what gets requested at inspection time and after any fire:
Insurance carriers treat this file as your due-diligence record. After a kitchen fire, the cleaning certificate is the first document an adjuster requests — and claims can be denied when there's no proof of scheduled professional cleaning. Every VentWash service produces this package as standard.
Two agencies touch your kitchen, and operators often mix them up. The fire side — your local fire marshal, under the Florida Fire Prevention Code — owns the exhaust system: hood, duct, fan, suppression, and the NFPA 96 cleaning schedule. The health side— DBPR's Division of Hotels and Restaurants — licenses the restaurant and inspects sanitation, and reviews ventilation plans before a new kitchen opens.
Locally that means Tampa Fire Rescue in Tampa, the Orlando Fire Department in Orlando, and county fire rescue for unincorporated sites — each city page in our service area directory names the AHJ that inspects there. Non-compliance risks citations, fines, and in serious cases closure; a grease-loaded system found during inspection means a short-deadline re-inspection at best.
Related obligation on the same calendar: your kitchen fire suppression system requires semi-annual inspection under NFPA 96 and NFPA 17A. Different service, same inspector — keep both current.
Yes. The Florida Fire Prevention Code — adopted statewide under Florida Administrative Code Chapter 69A-60 — incorporates NFPA 96 by reference. Every commercial kitchen in Florida is legally required to have its exhaust system inspected and cleaned on the NFPA 96 schedule, enforced by the local fire marshal.
It depends on cooking volume and fuel: monthly for solid-fuel cooking (wood, charcoal), quarterly for high-volume operations (24-hour kitchens, charbroiling, wok cooking), semi-annually for moderate-volume kitchens, and annually for low-volume operations such as churches and seasonal businesses.
NFPA 96 requires the system be inspected and cleaned by properly trained, qualified, and certified persons acceptable to the authority having jurisdiction — in practice, a professional hood cleaning company. Kitchen staff may handle routine filter washing, but staff cleaning does not satisfy the code or produce the certificate inspectors request.
A certificate of performance naming the company, technician, service date, systems cleaned, and any deficiencies; a service sticker on the hood showing the last and next service dates; and increasingly, before/after photos proving the duct interior — not just the canopy — was actually cleaned.
NFPA 96's cleanliness benchmark: after cleaning, grease-contaminated surfaces in the hood, duct, and fan must be taken down to bare metal. The commonly cited threshold requiring cleaning is measurable grease accumulation of about 2,000 microns (roughly 2 mm) on system surfaces.
