Who may clean and inspect commercial cooking exhaust systems
The Massachusetts Department of Fire Services states that anyone who cleans and inspects commercial cooking exhaust systems must hold a certificate of competency from the State Fire Marshal.
Companies performing this work also have a state registration process. A restaurant should verify both the individual credential and the company information rather than relying only on a website badge or verbal claim.
Credentials do not replace a clear scope. The proposal should still identify the systems, accessible components, cleaning method, documentation, and any work that requires another trade.
Inspection, cleaning, and service labels
State guidance addresses inspection and cleaning of commercial cooking exhaust systems and requires service labels to communicate the result. Massachusetts provides label requirements and complaint forms related to missing, inaccurate, or noncompliant labels.
A label is not a substitute for an invoice, report, photographs, or repair records. Operators should maintain a file that allows management, ownership, insurers, and authorities to understand what was inspected or cleaned and when.
Frequency is based on the operation
The correct inspection frequency depends on the cooking operation and applicable requirements. Cooking method, volume, fuel, grease production, hours, system condition, and prior findings can all matter.
A restaurant should not copy another kitchen's schedule without evaluating its own operation. When in doubt, ask a properly credentialed provider and the relevant local authority.
What hood cleaning does not cover
Hood cleaning does not automatically include fire suppression system inspection, fire extinguisher service, electrical repair, fan repair, roofing, grease-trap pumping, appliance service, or building-code approval.
Do not accept a guarantee that cleaning alone will make a facility pass every inspection. The fire official or other authority makes the final determination within its jurisdiction.
Practical checklist
- Ask for the individual certificate of competency
- Ask for the company's current registration information
- Confirm insurance and the exact legal business name
- Require a written system-by-system scope
- Confirm how service labels and records will be provided
- Keep invoices, reports, photos, labels, and follow-up repair records
- Contact the local authority when a notice or requirement is unclear

Frequently asked questions
Clear answers without fake guarantees
Requirements and individual facility conditions can change. Verify current information before authorizing work.
Is NFPA 96 itself a Massachusetts license?
No. NFPA 96 is a standard. Massachusetts credentials are issued through the state process. Marketing language such as NFPA 96 compliant is not a substitute for verifying the individual and company credentials.
Can an unlicensed employee work under another person's credential?
Credential and supervision questions should be directed to the Massachusetts Department of Fire Services. Do not assume a company name alone answers who is authorized to perform or certify the work.
Who decides whether the system is compliant?
The relevant authority having jurisdiction makes official determinations. A cleaning company can inspect and document within its authorized scope, but should not misrepresent government approval.
Where can I verify the current rules?
