Who regulates fire extinguisher service companies in Minnesota?

Minneapolis and other city licensing authorities is the agency the research identified for this trade in Minnesota. Requirements and license classes change, so confirm the current rules with them directly.

How do I confirm the exact Minnesota requirements before my first job?

Contact Minneapolis and other city licensing authorities and confirm, in writing, the company license or registration, the technician certification, and any surety bond or insurance filing your scope needs. Requirements vary by jurisdiction — verify with your AHJ (authority having jurisdiction) before you take paid work. This page is a starting point, not legal advice.

If Minnesota has no state company license, can I just start?

Not without checking. Even where there is no state license for the trade, you typically still need a business license, sales-tax registration, liability insurance, and possibly a local registration — and the NFPA service standards still govern the work. Verify the full picture locally before you quote a job.

What must a fire extinguisher service tag say in Minnesota?

This research pass could not read a Minnesota service-tag rule, so this page states none. There is no national tag standard to fall back on and no national colour code: NFPA 10 mandates no tag colour, and the per-state rules that do exist disagree with each other. Ask Minneapolis and other city licensing authorities what a tag must carry here before you print one.

Licensed locally

Fire extinguisher service license requirements in Minnesota

Updated August 2026

Minnesota has no single statewide company license for this trade — it is licensed locally. Check the jurisdiction where you will work (Minneapolis and other city licensing authorities).

What the research found

State: Minnesota (MN)
Regulating agency: Minneapolis and other city licensing authorities
License / class: Fire extinguisher servicing license, Class A / Class B (City of Minneapolis)
Notes from the source: Company licensing is municipal, and Minneapolis runs a real one: a Class A or Class B license to test, fix and charge portable extinguishers. Separately, the state fire code requires the individual doing the maintenance to hold a certificate from an approved organisation, so "no state company license" does not mean nothing applies statewide.
Service tag: Verify with the agency

Verify with your AHJ. This is a research-derived starting point, not legal advice. Rules change, and local requirements stack on top of state ones, so the only answer that governs your work is the one you get from Minneapolis and other city licensing authorities and from your AHJ, the local authority having jurisdiction, before you take a paid job.

Which code edition applies in Minnesota

An NFPA standard carries no legal force until a jurisdiction adopts it, and jurisdictions adopt different editions, years apart, with local amendments. So the useful question is never "what does NFPA 10 say". It is "which edition has my authority adopted".

This research pass did not reach an adoption record for Minnesota, so this page names no edition. That is a gap in what we could read, never a finding that the state adopts nothing. Ask Minneapolis and other city licensing authorities which edition of NFPA 10 and which fire code are in force, and ask your authority having jurisdiction the same question, because the two answers are not always the same one.

What a service tag must carry in Minnesota

This research pass could not read a Minnesota service-tag rule, so this page states none. There is no national tag standard to fall back on: NFPA 10 mandates no tag colour, the popular "the colour tells you the year" rule is a vendor convention rather than law, and the state rules that have been read do not match each other. Ask Minneapolis and other city licensing authorities what a tag must carry here, in writing, before you print a run of them.

The per-state picture, and why the colour folklore is wrong, is laid out in the state-by-state tag requirements guide and what a fire extinguisher tag colour actually means.

The cadence underneath all of it

Whether or not Minnesota licenses this trade, the intervals your customers owe are set somewhere else, and one layer of them is federal. Under OSHA's portable fire extinguisher regulation, an employer subject to OSHA has to have extinguishers visually inspected monthly and put through an annual maintenance check, wherever the building is. The state's adopted edition of NFPA 10 and the local fire marshal stack on top of that floor.

The interval that surprises people is the pressure test, because it is not one number: it depends on the agent and the shell, and a unit on the wrong assumption reads as current for years when it is not. The full picture, with the section of the federal regulation each interval comes from, is in the federal extinguisher intervals guide, and the by-type test schedule is in hydrostatic test intervals by extinguisher type. To put dates against a specific unit, the free cadence lookup takes a manufacture date and an equipment type and returns the next dates due. It is a planning aid, never a verdict on a building.
