A kitchen exhaust inspection evaluates the condition and code compliance of a commercial cooking ventilation system — hood, filters, ductwork, fire suppression components, and the rooftop fan — without necessarily performing a full cleaning. It's how a fire marshal, insurer, or restaurant owner confirms the system is being maintained on the schedule NFPA 96 calls for and catches problems, like grease buildup or a damaged duct seam, before they become a fire hazard. Inspections and cleanings are related but distinct services, and knowing which one you're scheduling — and from whom — matters.
Inspection vs. cleaning: not the same service
A cleaning removes grease buildup from system surfaces down to bare metal. An inspection assesses whether that buildup, or other problems, exist and whether the system meets code — it may or may not include cleaning as part of the same visit. Some companies combine both in one appointment; others send a dedicated inspector first and schedule cleaning separately, especially in larger facilities where documentation and cleaning are handled by different specialists. IKECA's acCESI credential specifically certifies inspectors, distinct from the CECS credential for cleaning technicians, which reflects how the industry treats the two as separate skill sets.
What a thorough inspection checks
Grease accumulation throughout the system, measured against the "bare metal" standard NFPA 96 sets for a properly cleaned system — an inspector documents how much buildup exists in the hood, plenum, ductwork, and fan.
Filter condition and fit, since damaged, warped, or missing baffle filters let grease-laden air pass through unfiltered.
Duct integrity, including seams, access panels, and clearances to combustible construction, which matter for containing a fire if one occurs in the duct.
Fire suppression system components that interface with the exhaust system — nozzles, fusible links, and whether they're unobstructed by grease.
Fan condition and hinge kit function, confirming the exhaust fan can be safely tilted back for cleaning access and that the fan itself isn't caked with grease.
Documentation history — whether certification stickers, service reports, and prior inspection records are present and consistent with the cooking volume and required frequency.
How often inspections happen
NFPA 96 ties required cleaning frequency to cooking volume and fuel type, with solid-fuel cooking needing the most frequent attention, followed by high-volume and moderate-volume kitchens, and lighter-use kitchens less often — but the exact interval enforced in your area comes down to your local fire marshal, AHJ, or insurance carrier, which may set a stricter schedule than the code minimum. Many kitchens fold a visual inspection into every service visit and treat a more thorough documented inspection as an annual or semi-annual event; check your local requirements rather than assuming a national default.
Who requests an inspection, and why
Fire marshals and AHJs may inspect kitchens as part of routine fire code enforcement or after a complaint or incident.
Insurance carriers sometimes require documented inspections or cleaning records as a condition of coverage, particularly after a claim involving a kitchen fire.
Restaurant owners and property managers commonly request an independent inspection when taking over a lease, after a change in cleaning vendors, or simply to verify that a cleaning company's work is holding up between visits.
Red flags during an inspection
Be cautious of an inspector who won't document findings in writing or with photos, one who recommends an immediate full cleaning without explaining what specifically triggered that recommendation, or an outfit that performs both the inspection and the resulting cleaning with no separation of the assessment from the sales pitch — a second opinion is reasonable if the findings seem to justify unusually large or urgent work.
FAQs
Can the same company that cleans my hood also inspect it? Yes, and many do both — but if you want an independent check on whether a prior cleaning was adequate, consider a separate inspector for that specific question.
Do I need an inspection if I already get regular cleanings? Regular cleaning on schedule is the main defense against grease fire risk, but an inspection adds a documented, code-focused check of things a routine cleaning crew might not evaluate in depth, like duct seam integrity or suppression system interface.
What happens if an inspection finds a violation? The inspector or AHJ will typically specify what needs correction and a timeframe. Depending on severity, this can range from scheduling an overdue cleaning to requiring duct or suppression system repairs before the kitchen can continue operating.
How to choose and verify a kitchen exhaust inspector
Look for IKECA's acCESI-certified inspectors, a credential specific to assessing exhaust system condition and NFPA 96 compliance, and check the IKECA member directory for companies with certified staff in your area. The NFPA 96 standard resources explain the code an inspection is measured against. Our listings are compiled from public, source-backed records — we are an independent directory and do not certify or endorse any kitchen exhaust cleaning company, so verify current certification and insurance directly before hiring an inspector.
