$25,000 bond × 3% = $750, one-time per term. Fixed amount, fixed price, multi-year if you want it. (DLI filings run on a two-year cycle — a 2-year term lines up.)
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.
