Licensed Pool Contractor in Michigan: How to Verify Before You Hire

Michigan's warm summers create strong demand for pool installation, and the state has a licensing system that applies directly to pool contractors. Before you hand over a deposit for an inground or above-ground pool, you need to understand which Michigan licenses are required, who issues them, and how to verify each one. Getting this wrong can leave you with no legal recourse if the project goes sideways.

Does Michigan require a license to install a swimming pool?

Yes. Michigan requires pool contractors to hold a Residential Builder license from the Department of Licensing and Regulatory Affairs (LARA) when pool installation involves excavation, structural work, or connections to the home's utilities. The electrical connections to a pool require a separate licensed Electrical Contractor, and plumbing connections require a licensed Master Plumber. All are issued by LARA.

Michigan's Residential Builder license covers any work on one-to-four family residential structures, including constructing or altering structures on the property. Inground pool installation typically involves all of these elements: excavation that affects the surrounding property, structural concrete or fiberglass installation, and utility connections. The Michigan Occupational Code is explicit that compensation for this type of work requires licensure.

Where do you verify a Michigan pool contractor's license?

Search Michigan contractor licenses at michigan.gov/lara using the "License Search" feature. You can search by business name or individual name. The database shows the license type, license number, issue date, expiration date, and current status (active, expired, suspended). Always verify on the day you plan to hire, since licenses can expire or be suspended at any time.

For pool projects, verify three separate licenses: the Residential Builder license (for the pool company), the Electrical Contractor license (for the electrician doing pool wiring), and the Master Plumber license (for plumbing connections). Ask the pool contractor to provide all three license numbers and then verify each one independently at michigan.gov/lara.

What is the bond requirement for Michigan pool contractors?

Michigan requires Residential Builders to maintain a $10,000 surety bond as part of their licensing. This bond is designed to protect consumers if the contractor abandons the project, causes damage, or fails to complete the work. While $10,000 is less than the typical cost of a pool project, the bond is the state's minimum backstop and a necessary baseline for any contractor you hire.

In practice, reputable pool contractors carry significantly more liability insurance than the state bond minimum requires. Request a Certificate of Insurance showing general liability coverage of at least $500,000 per occurrence and confirm workers' compensation coverage for all employees. Call the insurer to verify the policy is active before signing.

What happens if I hire an unlicensed pool contractor in Michigan?

Hiring an unlicensed contractor in Michigan for residential construction work creates serious legal and financial exposure. Under the Michigan Occupational Code, an unlicensed residential builder cannot collect payment for their work through the courts — they have no right to enforce the contract. More directly, if an unlicensed contractor causes damage to your property or fails to complete the project, your options for recourse are severely limited.

Unlicensed contracting is a criminal misdemeanor in Michigan. LARA actively investigates consumer complaints and pursues enforcement actions against unlicensed contractors. In 2024, LARA issued dozens of consent orders and license revocations against contractors in the residential construction space. According to LARA data, over 50% of pool-related consumer complaints in Michigan involve contractors who are either unlicensed or operating outside their license scope.

What permits are required for pool installation in Michigan?

Michigan law requires building permits for all inground pool construction. The permit process involves a review of pool placement, barrier requirements (fencing), electrical systems, and plumbing connections. Local building departments issue permits and conduct inspections at multiple stages of construction. Electrical inspections are conducted by a state-licensed electrical inspector.

Michigan has strict pool barrier requirements under the Residential Code. Fencing around pools must meet specific height and gate requirements. A licensed pool contractor will be familiar with these requirements and will include barrier installation in the project scope. If a contractor doesn't mention permits or barriers, that is a significant red flag.

What should I check beyond the license?

License verification is the floor, not the ceiling. Beyond verifying the Residential Builder, Electrical, and Plumbing licenses, check the contractor's standing with the Michigan Builder's Association or Pool & Spa Association. Review complaint history on the Better Business Bureau. Ask for at least three references from pool projects completed in the last two years and actually call them.

Pool construction timelines typically run four to eight weeks for inground installations. Get a detailed written contract specifying the pool type, dimensions, materials, equipment brands and models, timeline with milestones, payment schedule, and warranty terms.
