How Often Does a Colorado Springs Commercial Kitchen Hood Need to Be Cleaned?

Ask ten restaurant owners how often their hood needs cleaning and you’ll get ten different answers, partly because the question runs two separate obligations together. The fire code sets how often your exhaust system has to be inspected, on a schedule keyed to what you cook. Cleaning is then required wherever that inspection finds grease — and NFPA 96 governs what that cleaning has to cover. For most working kitchens the two schedules converge, but knowing which is which is what keeps you defensible.

What the Code Actually Requires

Inspection intervals are not advisory. Colorado Springs enforces the 2021 International Fire Code and the city’s local amendments, and its commercial cooking provisions require that hoods, grease-removal devices, fans, ducts and associated components be inspected on a set schedule, by qualified individuals — with the fire code official able to approve a different interval where circumstances warrant. Where an inspection finds grease accumulation, the affected components must be cleaned.

So the question an inspector from the Division of the Fire Marshal is really answering is not whether your system has been cleaned recently enough. It is whether the system was inspected on schedule, and whether whatever that inspection found was cleaned and recorded. A kitchen producing real grease volume fails the second test every time it skips the first. The wider legal framework behind all of it is set out in our guide to NFPA 96 compliance in Colorado Springs.

Monthly: Solid Fuel Operations

Solid fuel carries the shortest interval in the code: monthly inspection for any operation using solid fuel-burning appliances — wood-fired pizza ovens, mesquite and charcoal grills, and any open wood flame. These produce considerably higher grease and particulate loads than gas or electric cooking, and in practice a monthly inspection on a solid fuel system almost always finds enough accumulation to require cleaning. Treat monthly hood cleaning as the working assumption for these kitchens rather than the exception.

Every Three Months: High-Volume Cooking

The code puts high-volume cooking on a three-month inspection cycle, and it names the characteristic operations: 24-hour cooking, charbroiling and wok cooking. That last pair matters more than owners expect. A full-service restaurant with a charbroiler sits in this tier regardless of its overall covers, and so does any kitchen running a wok station. Add near-continuous operations with constant fryer use and this captures a large share of Colorado Springs kitchens that assume they are on a longer cycle.

Every Six Months and Annually: Everyone Else

Cooking operations that do not fall into the categories above default to a six-month inspection cycle. That covers a lot of moderate-volume full-service kitchens, hotel dining rooms, healthcare and corporate cafeterias and brewpub food programs — provided they are not charbroiling, wok cooking or running around the clock.

Low-volume operations get twelve months. The code names places of religious worship, seasonal businesses and senior centers; community centers and day camps that cook a handful of times a year sit here too.

The interval changes but the obligation attached to it does not. At every tier the inspection has to be carried out by qualified individuals, anything found has to be cleaned, and both have to be recorded.

How to Confirm Which Interval Applies to You

Work through these in order and stop at the first one that describes your kitchen:

1. Do you use any solid fuel-burning appliance — wood, charcoal, mesquite? Every month.
2. Do you charbroil, cook on a wok range, or operate 24 hours? Every three months.
3. Are you a low-volume operation — a place of religious worship, a seasonal business, a senior center or similar? Every twelve months.
4. Anything else? Every six months.

Three rules settle most of the awkward cases. Where a kitchen spans more than one category — a gas line plus a single wood-fired oven, say — the shorter interval governs the whole system, because the exhaust run is shared. If you cannot establish when the system was last inspected or cleaned, treat yourself as due: without a dated, attributable record there is nothing for an inspector to verify against. And your fire code official can approve a different interval for your specific operation, so if you have been given one in writing, that is the one that applies to you.

One caution about reading the code as a ceiling rather than a floor. A six-month inspection cycle does not mean six-month cleaning is adequate for your kitchen — it means that is how often somebody qualified has to look. If your ducts are loading up in eight weeks, the code requires cleaning at every inspection, and your insurer will expect a maintenance record that matches your actual grease production rather than the minimum schedule. What happens when the record does not hold up is set out in what happens when your Colorado Springs restaurant fails a fire inspection.

Building a Schedule That Keeps You Covered

Kitchen Guard of Colorado starts with a thorough assessment of your kitchen type, cooking volume, and current system condition before recommending a service frequency. We then build a recurring maintenance schedule around your operation — so you’re always within your compliance window, never scrambling before an inspection. Kitchen Guard works with full-service restaurants, hotel kitchens, healthcare cafeterias, school food service operations, and brewpubs across El Paso County. If you’re unsure which inspection interval applies to your equipment, we can assess your setup and put you on the right schedule — before an inspector does it for you.
