Minnesota Contractor License Lookup & List - DLI

Minnesota Contractor License List and DLI License Lookup (businesses only)

Every licensed Minnesota contractor business, from the Minnesota Department of Labor and Industry's (DLI) official nightly license files. About 33,000 active contractor businesses: residential building contractors, remodelers and roofers (about 10,800), electrical, technology-systems and sign contractors (about 3,600), plumbing contractors and pipelayers (about 2,000), HVAC/mechanical contractors with a mechanical bond (about 2,500) and registered construction contractors (about 14,000). Each row has the business name, DLI license number, license type, status, first-licensed and expiration dates, enforcement-action flag, business phone, address, city, state and ZIP.

No browser, no proxies, no login, no API key. The Actor downloads DLI's official CSV exports, so a full run takes about 15 seconds.

Three ways to use it

1. New-contractor leads. Set licensedWithinDays (for example 7 or 30) to get every contractor business Minnesota licensed or registered in that window, newest first. DLI refreshes the files nightly, so schedule it daily or weekly.
2. Full Minnesota contractor list. Leave licensedWithinDays at 0 and filter by category, city, ZIP or business name. Use expiresFrom / expiresTo for renewal prospecting.
3. Bulk DLI license lookup / verification. Paste license numbers into licenseNumbers to check status, type, expiration and enforcement flag for a whole subcontractor list in one run.

Who uses this

• Lumber yards, building-supply, electrical, plumbing and HVAC distributors prospecting newly licensed Minnesota contractors.
• Insurance, surety and bonding agents, including renewal prospecting by expiration date.
• Construction software, estimating, financing and payments companies selling to contractors.
• General contractors, property managers and home-service marketplaces verifying subcontractors in bulk.

Privacy by design

• Businesses only. Personal licenses (journeyworker and master electricians and plumbers, qualifying persons, technicians) are never output. Business licenses held under a person's name (sole proprietors) are dropped unless the trade name is a registered entity, and then the address and phone are blanked. RUN_SUMMARY.droppedPersonalLicense and droppedPersonName show the counts.
• No email addresses. DLI's files include an email column; this Actor never outputs it.

Common questions

Is this data legal to use? Yes. DLI publishes these exports on its license lookup page for anyone to download, sort and filter, and refreshes them nightly.

How fresh is it? Each run downloads the current files. RUN_SUMMARY.files shows each file's last-modified time (usually early that morning).

How do I check a Minnesota contractor license? Paste the number into licenseNumbers, or part of the business name into keywords with activeOnly off. You get type, status, expiration and an enforcement-action flag. Always confirm on the DLI license lookup (verifyUrl) before you hire.

Does Minnesota require a contractor license? Residential building contractors, remodelers and roofers need a DLI license; electrical and plumbing contractors need a DLI contractor license; HVAC/mechanical contractors need a mechanical contractor bond; and many other construction contractors must register with DLI. This Actor covers all five.

How much does it cost? Free to try with Apify's free plan ($5/month credit, no credit card), which covers about 1,600 records a month. After that it is $3.00 per 1,000 results, plus a fraction of a cent per run.

Can I get new contractors automatically every week? Yes. Save your filters as a task and add a weekly Schedule with licensedWithinDays: 7. Send each batch to Google Sheets, Slack, email, Zapier, Make or n8n under Integrations.

Can I call it from code or an AI agent? Yes. Use the Apify API or the Python/JavaScript clients, or connect it to Claude, ChatGPT or Cursor through the Apify MCP server.
