Michigan Contractor Licensing: What to Check Before Hiring

Why Michigan Contractor Licensing Is Non-Negotiable

Michigan has some of the most clearly defined contractor licensing laws in the Midwest — and for good reason. Whether you're adding a tornado safe room in Kalamazoo, reinforcing a basement shelter in Macomb County, or repairing storm damage in the Thumb region, the contractor you hire must be properly licensed under state law.

Michigan's contractor licensing framework is administered by the Michigan Department of Licensing and Regulatory Affairs (LARA) through its Bureau of Construction Codes (BCC). The state does not issue a single blanket "general contractor" license. Instead, it regulates specific trades and residential construction activities through a tiered system of licenses, registrations, and permits — and the rules vary significantly depending on the scope of work and the trade involved.

The bottom line for homeowners: any person or company performing residential construction or remodeling work valued at $600 or more (including labor and materials) is required by law to hold either a Residential Builder license or a Maintenance & Alteration (M&A) Contractor license. If your contractor cannot show you a valid license before work begins, stop the conversation there.

The Two Main License Types You'll Encounter

When hiring for home improvement, storm shelter installation, or structural work in Michigan, you'll most commonly encounter these two license categories:

• Residential Builder License: Covers full residential construction and renovation projects — including garages, additions, safe room installations, and complete remodels. A builder with this license can hire and oversee subcontractors across multiple trades under a single project.
• Maintenance & Alteration (M&A) Contractor License: Issued to specialists in specific trades such as roofing, masonry, insulation, concrete, excavation, and carpentry. If you're hiring a roofing contractor after a tornado or a concrete crew to pour a safe room foundation, this is the license type to verify.

Both license types are issued by LARA's Bureau of Construction Codes and are valid for three years, expiring on May 31st of the renewal year. Contractors must complete 21 hours of continuing education during the first six years of licensure to renew.

Specialty Trade Licenses to Know

Beyond general residential builder licenses, Michigan also independently licenses several key trades that may be involved in safe room or structural projects:

Michigan does not offer reciprocity for residential builder licenses — meaning out-of-state contractors who followed a storm or disaster into Michigan must still fulfill all Michigan licensing requirements before performing work on your home. Be especially cautious after major weather events when out-of-state crews flood the market.

How to Verify a Michigan Contractor's License

Don't take a contractor's word for it — always verify independently. Here's your step-by-step checklist:

1. Search the LARA MiPLUS Portal: All active Michigan builder and contractor licenses are searchable at Michigan.gov/LARA. Use the "Find / Verify a Licensed Professional or Business" tool to confirm the license is current, not expired or suspended.
2. Confirm the License Category Matches the Work: A roofing M&A license does not authorize full structural work. Make sure the license type aligns with the scope of your project.
3. Check the Expiration Date: Licenses expire every three years on May 31st. An expired license is the same as no license.
4. Verify Workers' Compensation Insurance: Michigan law requires workers' comp for employers with three or more employees, or with at least one employee working 35 or more hours per week. Ask for a current certificate of insurance.
5. Ask for General Liability Insurance: While Michigan does not mandate a specific minimum for state licensure, contractors typically carry $500,000 to $1,000,000 in general liability coverage — and most reputable ones do. Always get a certificate naming you as an additional insured.
6. Confirm Local Permits and Bonds: State-level surety bonds are not universally required, but many municipalities — including Oakland County and St. Clair Shores — require local contractor license bonds. Always ask your contractor whether local permits have been pulled for the job.

Red Flags to Watch For

• Contractor asks for full payment upfront before work begins
• No physical business address or only a P.O. Box
• Unlisted phone number or no online presence
• Pressures you to "skip the permit" to save money
• Cannot produce a license number on the spot
• Arrived in your neighborhood unsolicited immediately after a storm

What Happens If You Hire an Unlicensed Contractor?

The consequences of hiring an unlicensed contractor in Michigan fall on both parties — but homeowners often bear the greatest financial risk. If a contractor is caught performing unlicensed work, initial violations can result in fines ranging from $5,000 to $25,000, a jail term of up to one year, or both. Repeated violations carry potential jail time of up to two years.

But here's the risk to you as a homeowner: work performed without a proper license may void your homeowner's insurance policy, fail municipal inspections, and create significant liability if someone is injured on the job. If an unlicensed worker is hurt on your property, you could be held personally responsible. When it comes to life-safety installations like tornado shelters and safe rooms, cutting corners on licensing is never worth it.

Michigan Building Code: What Changed in 2025

As of May 1, 2025, the updated Michigan Building Code (MBC) took effect statewide. The 2025 MBC is derived from the International Building Code with specific Michigan amendments. Any contractor performing structural work — including safe room construction, storm shelter installation, or post-storm repairs — must be working to these updated standards. Ask your contractor directly: "Are you familiar with the 2025 Michigan Building Code, and will this project be permitted and inspected?" A confident yes is the right answer.

The Bottom Line: License Verification Protects Your Family

Michigan's active tornado season and increasingly severe spring storms across counties from Washtenaw to Montcalm make properly built safe rooms and storm shelters a genuine life-safety investment. That investment is only as good as the contractor who builds it.

Before signing any contract:

• Look up the license at Michigan.gov/LARA
• Confirm insurance with certificates in hand
• Require that permits be pulled before work starts
• Check that the license type matches your project scope
• Get everything in writing — scope, timeline, payment schedule, and warranty
