How Often Does NFPA 96 Require Hood Cleaning in Alberta?

Short answer: NFPA 96 Table 11.4 sets your cleaning schedule by what you cook and how much. Solid-fuel cooking and 24-hour or high-volume frying operations require monthly cleaning. Most standard commercial kitchens — the majority of restaurants in Red Deer — fall under quarterly. Low-volume kitchens like churches, seniors' centres and seasonal concessions are semi-annual. Alberta doesn't publish a separate schedule; the Alberta Fire Code requires exhaust systems be kept free of grease accumulation, and NFPA 96 is the benchmark your fire inspector and your insurer will measure you against.

The Three Tiers, With Central Alberta Examples

Where Operators Get It Wrong

Two mistakes come up constantly. First, owners assume "annual" is fine because that's what their last contractor scheduled. Annual is not a tier in Table 11.4 — the only annual item is inspection of systems serving solid-fuel or low-volume equipment, not full cleaning of a working restaurant. Second, seasonal operators forget the schedule follows operating months. A food truck with a fryer needs monthly cleaning while it's running, not once before the season starts.

Solid fuel is the tier people miss most often. If you burn wood or charcoal, that appliance needs its own dedicated exhaust system, and the monthly requirement applies regardless of how busy you are.

Bare Metal Is the Real Standard

Frequency is only half of it. NFPA 96 requires the system be cleaned to bare metal where accessible — hood, filters, the full length of horizontal and vertical duct, and the fan. A wipe-down of the hood canopy alone will not pass an inspection, and it's the ductwork above the ceiling that actually carries fire. Ask for before-and-after photos of the duct interior and a service sticker showing the date and the areas cleaned.

Typical Costs in Central Alberta

Most single-hood restaurant jobs in this area run $400–$900. Multi-hood kitchens with long rooftop duct runs typically land in the $1,200–$2,500 range. Rural sites outside Red Deer sometimes carry a travel charge.
