Bonding in Minnesota

A surety bond is a 3-party promise. The contractor (the principal) pays a surety company for a bond that a customer, subcontractor, or a government entity (the obligee) can draw against if the contractor breaks the rules the bond covers. The surety pays valid claims up to the bond face value. The contractor then owes the surety for what the surety paid out. A bond protects the public. It is not insurance for the contractor. Minnesota uses a mix of state-issued license bonds for specific trades and public-works bonds for government projects. Keep the categories separate. 1. Electrical Contractor license bond. The Minnesota Department of Labor and Industry requires firms holding an Electrical Contractor license to file a license bond with DLI. The bond runs to the state for the benefit of persons injured by the licensee's failure to perform work in accordance with Minnesota Statutes Chapter 326B. The Master Electrician of record is the underlying individual license; the contractor registration (and its bond) is what authorizes the firm to contract and permit in Minnesota. 2. Plumbing Contractor license bond. Minnesota DLI requires a license bond from Plumbing Contractors under Minnesota Statutes Chapter 326B. The bond runs to the state for the benefit of persons injured by the licensee's failure to perform plumbing work in compliance with the Minnesota Plumbing Code (Minnesota Rules Chapter 4714). 3. Mechanical Contractor bond (HVAC and gas). Minnesota Statutes section 326B.197 requires a $25,000 bond filed with DLI for any person installing gas piping, heating, ventilation, cooling, air conditioning, fuel-burning, or refrigeration equipment. Minnesota does not separately license HVAC technicians at the state level; the mechanical contractor bond is the state-level compliance instrument for HVAC firms.

Many Minnesota cities and counties require their own contractor license bond on top of the state filings. Amounts and obligees vary by ordinance. Confirm the local requirement in each city and county where you will pull permits. 5. Public works bonds (Minnesota Statutes 574.26 to 574.32, the Public Contractors' Performance and Payment Bond Act). A contract with a Minnesota public body for public work is not valid unless the contractor provides (a) a performance bond to the public body conditioned on completion and indemnity, and (b) a payment bond for the benefit of all persons furnishing labor and materials. The bond penalty must not be less than the contract price; payment bonds are generally mandated for contracts exceeding $175,000. Subcontractors and suppliers on bonded public jobs pursue claims against the payment bond rather than filing liens against public property.

On private Minnesota projects, subcontractors and suppliers use the mechanic's-lien procedures in Minnesota Statutes Chapter 514. An owner or original contractor may post a bond to clear liens under Chapter 514; that is a project-specific tool, not a state license bond. Premium math. A surety charges an annual premium, typically 1% to 3% of the bond face value for a contractor with strong credit and no prior claims. Weaker credit, tax liens, prior surety losses, or a new business can push the rate to 5% to 10% or more. Public works performance and payment bonds are priced per job, usually 0.5% to 3% of the contract price depending on contract size, job type, and the contractor's financial statements. Bond, insurance, and workers' compensation are separate requirements. A Minnesota contractor typically carries the state license bond required for the trade held, the $25,000 mechanical contractor bond if doing HVAC or gas work, any city-specific bond, general liability and workers' compensation insurance, and statutory performance and payment bonds on any qualifying public contract. Confirm each requirement against the current statute and contract before you assume you are compliant.
