Does Ohio license pool contractors? What to check

No. Some states license pool builders directly. Ohio does not. The state board that licenses construction trades, the Ohio Construction Industry Licensing Board (OCILB), issues licenses to electrical, heating, ventilating and air conditioning, plumbing, hydronics and refrigeration contractors who pass its exam. Pool construction is not on that list.

The Ohio Attorney General puts it plainly in its home improvement tips: state law does not require home improvement contractors to be licensed, but many Ohio cities do. That leaves the checking to local building departments and to you. A builder who says they are "state licensed to build pools" in Ohio is describing something that does not exist, so ask what they mean.

It varies by city, village, township and county. Some keep a contractor registration list. Others check the contractor's paperwork each time a permit is issued. Summit County's Department of Building Standards is a good example of how this is changing. In 2024 it replaced its annual contractor registration, with its yearly fee and $10,000 bond, with a permit-based process. Contractors still have to provide proof of liability insurance, a state license if one applies to their trade, and a tax ID number when they apply for permits.

Whatever your town's system, an inground pool needs a permit, and the builder should be the one pulling it. A permit in the contractor's name means the contractor's paperwork has been through the building department and the work will be inspected. We handle the permits on every pool we build.

If a builder suggests you pull the permit yourself as the homeowner, treat it as a warning sign. It moves responsibility for code compliance onto you.

A pool runs on electricity next to water, and some pools add gas for a heater. Those are the parts of the job where state trade licenses can come in. OCILB licenses electrical, plumbing and hydronics contractors, among others, and you can look up any license number on the Ohio Department of Commerce's site.

Whether your town requires a state-licensed electrical contractor for residential pool wiring is set locally, and your building department can tell you. Either way, ask the builder who does the electrical work, whether it is their own crew or a subcontractor, and for the license number if one applies. The bonding, the equipment wiring and the run from your panel will all be inspected, and you want them done by someone who does this work routinely.

More than many people realize. Ohio Revised Code Chapter 4722 covers home construction services, which it defines as construction on a residential building, including repair, improvement, remodeling or renovation. A residential building means a one-, two- or three-family dwelling and any accessory construction incidental to it. Under section 4722.02, a supplier performing a home construction service costing $25,000 or more has to use a written contract that includes:

• the supplier's name, physical business address, business phone number and taxpayer identification number
• the owner's name, address and phone number
• the address of the property
• a general description of the work, including the goods and services to be furnished
• the anticipated start and completion dates or periods
• the total estimated cost
• any installation, delivery or other cost the estimate does not cover
• a copy of the supplier's certificate of insurance showing general liability coverage of at least $250,000
• dated signatures of the owner and the supplier

The same section covers surprises. If unforeseen but necessary extra costs add up to more than $5,000 over the whole contract, the owner has a right to an estimate of those costs before the work is done, written or oral as the owner chose in the contract. A firm-price contract that rules out extra charges does not need that notice.

With inground pools typically well above $25,000, a pool contract will usually be over that threshold. If a builder hands you a one-page quote with a signature line and no insurance certificate, ask why.

Section 4722.03 lists practices a home construction service supplier may not engage in. Among them: starting work without a compliant written contract, charging for excess costs the owner did not approve, failing to perform the work in a workmanlike manner, intentionally understating the estimated cost, misrepresenting the quality of the work or materials, failing to give the owner copies of documents the owner signs, and failing to refund payment for goods or services not delivered under the contract.

It also requires disclosure before work starts if part of the job will be done by someone other than the supplier or its employees and the contract disclaims any warranty on that part. On a pool, that can mean a subcontracted electrician, concrete crew or fence installer. Ask who does each part.

Chapter 4722 makes it a violation for a supplier to fail to perform the work in a workmanlike manner, and section 4722.01 defines the term. Workmanlike manner means construction that meets or exceeds the minimum quantifiable standards promulgated by the Ohio Home Builders Association.

That gives a homeowner something concrete to point to if work is plainly substandard. It is a floor, not a finish standard, and it is no substitute for a clear scope. The best protection is a contract that names the shell model, the equipment by brand, the deck size and finish, the backfill material and the drainage plan, so there is no argument later about what was promised.

The Ohio Attorney General's checklist for home improvement contracts is a solid starting point, and it applies well to pools:

• Check with local officials whether permits are required, then confirm the builder will pull them.
• Get references and actually call them. Ask to see a finished pool in person if you can.
• Ask for proof of licenses, insurance and bonding where they apply.
• Check the Better Business Bureau and the Attorney General's office for complaints.
• Get written estimates from more than one contractor. The Attorney General suggests at least three.
• Make sure the contract states any contractor guarantee or warranty, along with oral promises.

Two more checks take a few minutes. Search the business on the Ohio Secretary of State's business search to confirm the company name on the contract is a registered, active entity. Our legal name is Ohio State Pools, Inc. And read the builder's online reviews for the pattern, not the stars: how they handle problems, whether they show up when they say, and whether the pools still look good a few seasons on.

If you can, ask to see a job in progress, not only finished pools. A backyard in the middle of a build tells you a lot: how the site is kept, how the dig is protected from water, whether the crew treats the neighbor's lawn with care. Finished pools all look good in photos. The work in between is where builders differ.

General liability is the floor. Chapter 4722 has the contract include a certificate showing at least $250,000 of general liability coverage, and Summit County asks for proof of liability insurance with each permit. On a pool, where an excavator and loaded trucks will cross your lawn and possibly your driveway, many homeowners reasonably want more than the minimum.

Ask for the certificate to come from the insurance agent, not as a photocopy, and check the dates and the named business. Ask about workers' compensation coverage for the crew as well. If someone is hurt in your backyard, you want that handled by the contractor's coverage, not your homeowners policy.

The Attorney General advises against contracts that require a large down payment or full payment before the project is complete and inspected. Pool projects are commonly paid in stages tied to milestones such as excavation, shell set, deck and completion. What matters is that payments follow the work, that the schedule is written into the contract, and that the final payment comes after the pool passes inspection and is running. If you are financing, ask how the lender pays out. Some pool and home improvement loans fund in one lump sum, and HFS Financial, one of the lenders we work with, offers loans with no stage funding.
