When a fire inspector walks into a commercial kitchen, one of the first things they may ask to see is proof that the exhaust system has been cleaned. That proof usually takes the form of a hood cleaning certificate and the service records behind it. If you cannot produce it, you may have a problem even if the hood looks clean.
This post explains what a hood cleaning certificate is, what it should contain, and how to keep your paperwork inspection-ready.
What Is a Hood Cleaning Certificate?
A hood cleaning certificate is documentation from your cleaning contractor confirming that your kitchen exhaust system was cleaned on a specific date. It is often a sticker placed on the hood or system, together with a written service report. The certificate is evidence that the work was done, who did it, and when the next cleaning is due.
The standard behind this practice is NFPA 96, which addresses ventilation control and fire protection for commercial cooking operations. Local fire codes, which can vary by jurisdiction, adopt and enforce these requirements. If you want a deeper look at the standard itself, read our guide to NFPA 96 hood cleaning in Florida.
Why Inspectors Ask for It
Grease buildup in hoods, ducts and fans is a serious fire hazard. Inspectors cannot see inside every duct run, so documentation is how they confirm the system is being maintained on schedule. A current certificate shows that the cleaning is not just planned but completed. It also helps your insurance company and landlord see that you take fire safety seriously.

What a Good Service Report Includes
Not every certificate is created equal. A thorough record should include:
- The date of service and the name of the company that performed it.
- The areas cleaned, such as the hood, filters, ductwork, and exhaust fan.
- Any areas that could not be reached. If an access panel was missing or a section of duct could not be cleaned, the report should say so.
- Before and after photos, which are useful if the inspector asks questions.
- Recommendations, for example if a fan needs repair or additional access panels are needed.
- The next recommended cleaning date.
Keep the sticker visible and file the full report where managers can find it quickly.
How Often Should the Certificate Be Renewed?
The cleaning schedule depends on what you cook and how much. Kitchens with high-volume or grease-heavy cooking generally need cleaning more often than those with light cooking. Your fire code and cleaning contractor can help you set the right interval based on your menu and volume.
The important point is that the certificate should never be allowed to expire. Put the next due date on your calendar as soon as the work is done.
Mistakes That Cause Problems at Inspection
- Relying on a verbal promise. If the cleaning was done but not documented, it is hard to prove.
- Using a contractor who only cleans what is visible. A hood that looks clean can still have grease in the ducts above it.
- Losing the paperwork. Keep digital copies as well as paper.
- Ignoring access problems. If your system lacks proper access panels, the contractor may not be able to clean it fully, and that can show up in the report.
- Letting the schedule slip. Missed cleanings create gaps that are hard to explain.
A Simple Inspection-Ready Checklist
- Confirm the certificate sticker is current and visible.
- Keep the last few service reports in one folder.
- Make sure staff know who to call if an inspector arrives.
- Check that filters are in place and in good condition.
- Schedule your next cleaning before the current one expires.
