About this bond

What it is and who needs it.

What the mechanical bond actually guarantees

Minnesota does not issue a statewide mechanical contractor license, but under Minn. Stat. 326B.197 anyone who contracts to do gas, heating, ventilation, cooling, air conditioning, fuel-burning, or refrigeration work must give and maintain a $25,000 bond with the State, filed with the Department of Labor and Industry, Construction Codes and Licensing Division.

The bond is for the benefit of persons suffering financial loss because of the contractor's failure to comply with the State Mechanical Code. A party harmed by non-compliant mechanical work can recover against the bond, up to the $25,000 penal sum.

The DLI bond filing is generally valid for two years (a $100 filing fee at DLI, separate from the surety premium). It is not insurance for you — if the surety pays a claim, you repay the surety. Contractors who work to code treat the bond as a cost of doing business, not a risk.

FAQ

Common questions.

How much is the Minnesota mechanical bond?The premium is $219 — set by our carrier’s rate book for this bond. The $25,000 bond amount is set by statute, so there is no quote process. (DLI also charges a separate $100 filing fee.)

Do I pay the $25,000?No. You pay $219. The $25,000 is the surety's maximum liability to harmed parties — not a deposit, and nobody holds your money.

Do I need a license too?Minnesota does not issue a statewide mechanical contractor license, but the $25,000 bond is mandatory under Minn. Stat. 326B.197 to contract gas/HVAC/refrigeration work. Local jurisdictions may have their own licensing.

Is there a credit check?Not on this bond — the application collects no credit information. Fixed-amount bonds like this one typically don't need one.

How long is the filing good for?The DLI bond filing is generally valid for two years, with a $100 renewal fee at DLI. You can buy a 1, 2, or 3-year surety term; a 2-year term lines up with the DLI cycle. We send renewal notices 60 and 30 days out.
