What Is NFPA 96? A Practical Guide for GTA Restaurant Owners
If you own or manage a restaurant, keeping your commercial kitchen clean is part of everyday business. But some of the most important areas aren’t always visible.
Grease and cooking residue can build up inside your hood, filters, ductwork, and exhaust fan over time. That’s why regular inspection and professional commercial hood and exhaust cleaning are important parts of maintaining a safer kitchen.
This is also where NFPA 96 comes in.
Here’s what restaurant owners across Toronto and the Greater Toronto Area (GTA) should know.
What Is NFPA 96?
NFPA 96 is the Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations, published by the National Fire Protection Association.
It addresses fire-safety considerations associated with commercial cooking operations, including kitchen ventilation and exhaust systems.
For restaurant owners, an important part of NFPA 96 involves managing grease and other combustible buildup within components such as:
✔ Commercial kitchen hoods
✔ Grease filters
✔ Exhaust ductwork
✔ Exhaust fans
✔ Other applicable exhaust-system components
The important thing to remember is that commercial hood cleaning isn’t only about making the visible hood look clean. Grease can travel farther into the exhaust system where it may not be easily seen.
Why Does NFPA 96 Matter for Restaurant Owners?
Every busy commercial kitchen produces heat, smoke, grease-laden vapours, and cooking residue.
Some grease is captured by the filters, but over time, contaminants can accumulate throughout other parts of the exhaust system.
Regular inspection helps restaurant operators understand the condition of the system and identify when professional cleaning is needed.
A proactive approach can help with:
✔ Managing grease buildup
✔ Maintaining a cleaner exhaust system
✔ Supporting commercial kitchen fire safety
✔ Keeping better maintenance records
✔ Identifying areas that need professional attention
Rather than waiting until the hood looks extremely dirty, restaurants should have an appropriate inspection and maintenance schedule based on their type of cooking operation.
How Often Should a Commercial Kitchen Exhaust System Be Inspected?
NFPA 96 establishes different inspection frequencies based on the type and volume of cooking.
Monthly
Solid-fuel cooking operations
Quarterly
High-volume cooking operations, including certain operations involving 24-hour cooking, charbroiling, or wok cooking.
Semi-Annually
Moderate-volume cooking operations
Annually
Low-volume cooking operations, including certain seasonal or limited-use facilities.
Important: Inspection Doesn’t Automatically Mean Cleaning
This distinction is important.
These are inspection frequencies, not a universal rule that every restaurant must have its hood cleaned on exactly the same schedule.
The actual need for cleaning depends on the condition of the exhaust system and the amount of grease or other combustible contamination found during inspection.
A high-volume restaurant using fryers or woks may accumulate grease much faster than a low-volume commercial kitchen.
What Parts of the Kitchen Exhaust System Need Attention?
Professional commercial kitchen exhaust cleaning goes beyond wiping down the visible hood.
Depending on the system and its condition, attention may be needed in several areas.
Hood
Grease and cooking residue can accumulate on interior hood surfaces above cooking equipment.
Filters
Grease filters capture contaminants generated during cooking and can become heavily coated over time.
Ductwork
Grease can travel beyond the filters and accumulate within accessible portions of the kitchen exhaust ducts.
Exhaust Fan
The exhaust fan is often located outside or on the roof, making it easy to overlook. Grease can accumulate around accessible fan components and surrounding areas.
A properly maintained exhaust system should therefore be considered as a complete system rather than just the visible hood.
Signs Your Hood & Exhaust System May Need Cleaning
Restaurant owners and kitchen managers should pay attention to noticeable changes in their exhaust system.
Some common warning signs include:
✔ Visible grease around the hood
✔ Heavily coated grease filters
✔ Persistent grease or cooking odours
✔ Grease buildup around exhaust equipment
✔ Reduced exhaust performance
✔ No clear record of the last inspection or cleaning
If you notice these signs, it may be time to have your commercial kitchen exhaust system professionally assessed.

How Often Does Your Restaurant Hood Need Cleaning?
There isn’t one answer that applies to every restaurant.
Your cleaning needs can depend on:
✔ Cooking volume
✔ Operating hours
✔ Type of cooking equipment
✔ Frying, wok cooking or charbroiling
✔ Type of fuel used
✔ Amount of grease produced
✔ Previous inspection findings
A restaurant operating long hours with high-volume cooking may require more frequent attention than a lower-volume kitchen.

Keep Records of Your Hood & Exhaust Cleaning
Good documentation can make commercial kitchen maintenance much easier to manage.
Restaurant owners should consider keeping records such as:
✔ Date of inspection or cleaning
✔ Areas inspected
✔ Areas professionally cleaned
✔ Before-and-after photographs
✔ Findings or recommendations
✔ Follow-up service information
Before-and-after documentation also provides greater transparency about the work completed.
NFPA 96 & Commercial Hood Cleaning Across the GTA
Restaurants throughout the GTA have different cooking volumes, equipment, menus, and operating hours.
A high-volume restaurant in Toronto or North York may have different cleaning needs from another commercial kitchen in Mississauga, Brampton, Vaughan, Markham, Scarborough, Etobicoke, or Richmond Hill.
That’s why professional restaurant hood cleaning in the GTA should consider the actual condition and operation of each kitchen rather than applying the same schedule to every business.
