Reviewed August 16, 2026. Kitchen exhaust inspection and cleaning requirements come from the code and edition adopted for the location, the authority having jurisdiction, and the actual system condition. NFPA 96 is an important model standard; it is not automatically the law everywhere.
Identify the controlling authority and edition
Start with the local fire authority. Ask which fire-code edition and NFPA 96 edition are adopted, whether local amendments apply, how the cooking operation is classified, who may inspect or clean, and what labels and records must be kept.
A health department, insurer, landlord, brand standard, or contract may impose additional conditions, but none should be assumed from a national web article. Keep the written local requirement with the facility records.
Inspection frequency is not automatically cleaning frequency
A common NFPA 96 inspection table used in adopted rules calls for grease-buildup inspection monthly for systems serving solid-fuel cooking; quarterly for high-volume operations such as 24-hour cooking, charbroiling, or wok cooking; every six months for other operations; and annually for specified low-volume operations. The edition and local adoption must be confirmed.
Under that model approach, cleaning follows when inspection finds grease deposits. The table should not be rewritten as a universal promise that every system is cleaned on those calendar dates. A local authority may use different categories, documentation, personnel rules, or intervals.
Know what system is being addressed
The exhaust path may include the hood, grease-removal devices, plenum, ducts, fan, and related components. System design, access panels, roof conditions, and other equipment affect what can be inspected and cleaned.
Staff should not open ducts, access roofs, or perform hazardous inspection work based on this article. Use personnel accepted for the work by the local authority and follow the system and safety instructions.
Records and labels are local
Some fire authorities require a service label and an on-site report; the required fields and retention period vary. A sticker alone does not establish that every required area was accessible, inspected, or cleaned.
Keep the provider’s scope, date, system identification, findings, inaccessible areas, work completed, deficiencies, photos when required, and next action. Match those records to the locally required form and retention period.
Handle wastewater under the applicable rule
Ask how wash water, grease, and solid waste will be contained and disposed of. Do not send hood-cleaning wastewater to a storm drain. Do not assume it may be sent to a grease interceptor or sanitary sewer without approval; local wastewater rules control.
For proposal and provider questions, use the kitchen hood cleaning hiring checklist.
Frequently asked questions
Does NFPA 96 automatically apply to every restaurant?
No. Confirm the adopted code, edition, amendments, and system scope with the local fire authority.
Are the monthly, quarterly, six-month, and annual periods cleaning schedules?
They are commonly presented as grease-buildup inspection categories in NFPA-based rules. Cleaning is performed when required by the adopted rule and inspection findings.
Must the cleaner hold an IKECA certification?
IKECA is an industry credential, not a nationwide licence. Ask the local authority which training, certification, registration, or permit it accepts.
Does a service sticker prove compliance?
No universal claim is justified. Keep the label and report required locally, but also review scope, findings, inaccessible areas, and unresolved deficiencies.
