NFPA 96 Explained for Restaurant Owners
By Texas Hood Cleaning Co. · General planning information
NFPA 96 is the standard the fire marshal is working from when they look at your kitchen exhaust — but almost no restaurant owner has read it. Here is the plain-English version of what it requires and why it exists.
What NFPA 96 is
NFPA 96 is the National Fire Protection Association’s "Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations." In plain terms, it’s the rulebook for how commercial kitchen exhaust systems are built, maintained, and cleaned so they don’t start or spread fires. Most Texas jurisdictions adopt it by reference through the fire code, which is why your local marshal enforces it.
What it requires of you
For an operating restaurant, the standard comes down to a few practical obligations:
- Inspect grease buildup at the applicable monthly, quarterly, semiannual or annual baseline; clean based on deposits and applicable requirements.
- Clean the entire system to bare metal where accessible — hood, filters, ducts, and the rooftop fan.
- Keep the system in good working order: proper filters in place, cleanout panels accessible, fan functioning.
- Document each cleaning with a date and the name of the servicing company.
The parts of your system it covers
NFPA 96 treats the exhaust as one connected system, and each part matters:
- The hood and baffle filters that capture grease-laden vapor.
- The duct run — vertical and horizontal — where grease travels and collects.
- The rooftop exhaust fan, the high point where grease pools and can drip onto the roof.
- Any fire-suppression system tied to the hood (inspected separately by a suppression company).
Why it exists
Grease is fuel. Every time you cook, a fine film of grease-laden vapor travels up the hood and through the duct to the fan. Left to build, that grease becomes a fire load running through your ceiling and roof — and a duct fire spreads fast and hot. NFPA 96 exists to keep that fuel from accumulating. The documentation requirement exists so inspectors and insurers can verify it’s actually happening.
Staying on the right side of it
Keep inspections, cleaning and corrective work documented. Confirm the adopted requirements for your property with the local authority and qualified technician. Retain reports of inaccessible or uncleaned areas and arrange follow-up when needed. A service label does not by itself establish that every part of the property complies.

FAQ
Is NFPA 96 law in Texas?
NFPA 96 is a standard, but Texas jurisdictions adopt it by reference through their fire codes, which makes it enforceable. Your local fire marshal inspects to it.
Does NFPA 96 apply to my small kitchen?
If you operate a commercial grease hood over a cook line, yes — regardless of size. Frequency scales with volume, so a low-use kitchen simply has a longer interval.
What’s the most common compliance mistake?
Assuming a hood wipe-down counts. The standard requires the full system — duct and rooftop fan included — cleaned to bare metal where accessible and documented.
Does NFPA 96 cover my fire-suppression system?
It addresses fire protection for cooking operations, but the wet-chemical suppression system itself is inspected and serviced by a licensed suppression company, separate from hood cleaning.
