Licensing rules change and cities add requirements on top of state law. Use this page as orientation; the lookup links below are the authoritative check before you sign a contract.

Who must be licensed in Minnesota

Minnesota requires residential building contractors and remodelers to hold a state licence from the Department of Labor and Industry (DLI) when they build or improve dwellings, with licence categories tied to project type and value. Electricians, plumbers, and HVAC technicians hold separate DLI credentials. Building permits are issued locally under the Minnesota State Building Code. Verify contractor and trade licences on DLI’s licence lookup before signing — a Minnesota business registration alone does not authorize regulated construction work.

Contractor hiring checklist

Insurance and bond minimums

DLI residential contractors must maintain general liability insurance and workers’ compensation as required by statute. Trade licences carry programme-specific requirements. Request COIs from insurers.

Who issues permits

Minnesota adopts a statewide building code enforced by local building officials. DLI licences who may contract; municipalities issue permits and inspections.

Homeowner permits — can you pull one, and should you

Owner-occupiers may obtain permits in many cities for work on their own home. Regulated trades require DLI-licensed contractors even when the owner holds the permit.

Deposits, cancellation rights, and liens

Deposit rules: Minnesota’s contractor laws include disclosure and warranty requirements for residential work — compare payment schedules to DLI consumer guidance rather than assuming unlimited deposits are lawful.
Rescission / cooling-off: Home solicitation sales may include cancellation rights under Minnesota law and the federal Cooling-Off Rule when applicable.
Mechanic's lien timeline: Minnesota mechanic’s lien statutes (Minn. Stat. Chapter 514) set pre-lien notice and filing deadlines. Owners should use waiver forms at each payment.

Where to file a complaint

File licence complaints with DLI. Warranty and contract disputes may go to the Attorney General. Permit violations go to the local building official.

If you hire someone unlicensed

Unlicensed residential contracting can void warranty protections and fail inspections. Unlicensed electrical or plumbing work creates fire and freeze-damage risk in Minnesota winters.
