Ask the contractor for a license number in writing, then look it up yourself on LARA's state license search at michigan.gov/statelicensesearch. Read the license type (residential builder or maintenance and alteration), the craft or crafts listed, the term and the status. Then make sure the name on the license is the company named in your contract.
Before you look anything up
A license check takes a few minutes and answers one narrow question: may this person or company lawfully take this work in Michigan. Michigan has no foundation repair license, so you are looking for a residential builder license or a residential maintenance and alteration license whose crafts cover the job, a point our penalties guide explains. Contractors taking $600 or more in labor and materials must hold one, according to LARA’s homeowner guidance.
Get two things from the contractor first: the exact company name as it will appear on the contract, and the license number, in writing. A number given by phone and never repeated on paper is a number you cannot check later.
Step by step on the LARA lookup
LARA’s page for finding or verifying a licensed professional or business lists residential builders and links to the state license search at michigan.gov/statelicensesearch. Open it yourself instead of following a link the contractor sends you.
- Search by the license number, or by the company name if you only have that.
- Open the record and read the name. Is it the company on your contract, or the owner as an individual? A company license and an owner’s personal license are different records.
- Read the license type: residential builder, or maintenance and alteration.
- Read the craft or crafts on a maintenance and alteration license. LARA says the trades a contractor may practice are listed on the license. The possible ones are carpentry, concrete, excavation, insulation work, masonry, siding, roofing, screens and storm sash, gutters, tile and marble, house wrecking, swimming pools and basement waterproofing.
- Read the status and the dates. A license is issued for three years. An expired or suspended status is a reason to stop.
Residential builder licenses cover building a complete residential structure and maintenance and alteration work. A maintenance and alteration license covers the specific trades named on it, and a licensee may do work in another craft only if it is incidental and supplemental to the licensed craft. If the crack injection company holds only a roofing craft, ask why that covers your wall.
Match the craft to your job, with caution
The statute names no craft for foundation work, so the match is a judgment. Concrete, masonry, excavation and waterproofing a basement are the crafts that plausibly fit crack repair, piers, drain tile and wall work, and a residential builder license fits anything. That is our reading and not LARA’s. A contractor with a sensible answer can say which of their crafts they are relying on. If an answer is vague, ask LARA’s Residential Builders section at 517-241-9309, or the Licensing Section at 517-241-9316.
Note two limits. Sump pumps, drains tied to a plumbing system and electrical work for a dehumidifier or a radon fan fall under other trades’ licenses, which you check separately. And there is nothing to look up for radon testers and mitigators, since EGLE says they are not licensed or regulated in Michigan. We make no claim either way about home inspectors; we found no primary source and left it out.
Company or owner
When a company holds the license, MCL 339.2405 requires it to designate a qualifying officer who passed the exam, holds an individual license and supervises the work. If that person leaves, the company license is suspended. So ask who the qualifying officer is, and check that the name on the contract, the license record and the person who walks your house line up. A salesperson is not the licensee.
LARA says the state license must be displayed at the place of business, and contractors and their salespersons must carry a pocket card that a homeowner may ask to see. A contractor who bristles at the request has told you something.
What the contract should contain
LARA lists what the contract should include: the company name, address, phone and license number; detailed specifications and any architect or engineer drawings required; start and completion dates; a statement that the contractor will obtain all required building permits; a warranty statement; and a right-to-cancel clause, which is three days if the sale was solicited and signed at your home. MCL 570.1114 adds a point that matters if a dispute ever reaches a court: a contractor has no construction lien right on a residential structure unless the work was under a written contract with changes in writing, and the contract must state that the contractor must be licensed and give the license number.
Ask for the warranty in writing and read who backs it, whether it transfers when you sell, and what voids it. Those three questions cost nothing and will tell you more than the brochure.
The three-day cancellation rule
Michigan’s home solicitation sales law, MCL 445.112, lets a buyer cancel until midnight of the third business day after signing. MCL 445.111 defines the sale as one over $25 that was solicited and agreed at the buyer’s residence, and excludes sales that follow negotiation at the seller’s place of business or a published ad. The rule does not appear to cover you when you called the contractor yourself, which is our reading of the definition, not a ruling. If a salesperson knocked on your door after a storm or phoned you and you signed in your kitchen, the right probably applies, and the contract should say so.
What a license does not prove
It does not prove the diagnosis is correct. The person who tells you that a wall must be pinned, a drain tile replaced or a crawl space encapsulated is often the person who sells it. A license says nothing about that conflict, and the lookup will not show it. Our engineer guide explains how to get a written read from someone with nothing to sell, and the cost guide explains how to compare quotes once you have it. Foundation companies pay us for referrals, and we pass your request to one company without checking its license for you. Do the check yourself before you sign, even if the company came from us.
If the check turns up a problem, or the work goes wrong later, LARA says to try the contractor first, then the local building inspector, and then a complaint to the Residential Builders section, within 18 months of completion. The foundation repair page and the basement waterproofing page say what the work involves.
Questions people ask
Where do I look up a Michigan contractor license?
Use LARA's state license search at michigan.gov/statelicensesearch, which LARA's Find or Verify a Licensed Professional page links to; residential builders are listed there. For licensing questions, LARA's Residential Builders section lists 517-241-9309, and the Licensing Section lists 517-241-9316.
Does a Michigan builder license last forever?
No. Residential builder and maintenance and alteration licenses are issued for three years. LARA says applicants must pass an examination, complete a minimum of 60 hours of courses before applying and be 18, and renewal requires continuing competency and a current copy of the Michigan residential code.
Can I cancel a contract I signed at my house?
Often, yes. MCL 445.112 lets a buyer cancel a home solicitation sale until midnight of the third business day after signing, and MCL 445.111 defines that as a sale over $25 solicited and agreed at your residence. It does not apply to sales that follow negotiation at the seller's business location or a published ad, and by our reading it does not apply when you called the contractor yourself.
Does a valid license prove the contractor is good?
No. It shows the person or company may lawfully take the work. It does not show their workmanship, their finances or whether they are the right person to diagnose your problem. Ask for references, a written scope and, for anything structural, an engineer's report.
Are radon contractors on the LARA lookup?
No. EGLE says radon testers and mitigators are not licensed or regulated in Michigan, so there is no state license to look up. Ask a radon contractor for references and more than one estimate instead.

Request sent
We passed your request about job to one foundation company serving your area. Keep your phone nearby.
- 1The company calls or texts from its own number, which may not be ours. It should say who it is and what it can do for you.
- 2Before you agree to any structural work, ask for an engineer's written report that the company did not write, and ask for the license number so you can check it yourself.
- 3Say no if the price or the plan does not make sense. A second opinion costs you a day and may save you a repair.
If you smell gas at any point, leave the house and call 911 and your gas utility from outside.
- Photograph every crack with a coin or ruler for scale, and mark each end of it with a pencil and the date.
- Note when you first saw it and whether it has grown.
- Find the age of the house and any past repair paperwork or warranty.
- Get at least two quotes, and an engineer's report for anything structural.
- Clear a path to the wall, crawl space hatch or sump pit so a visit does not start with moving boxes.
