Contractor disputes sit inside the state’s consumer protection framework, described in Ohio Consumer Sales Practices Act rights and remedies. This article covers which office takes a contractor complaint, what each one does with it, the estimate and cancellation rules Ohio imposes on home improvement work, and how an agency complaint relates to a court case for the money.
Which office takes a contractor complaint
Ohio has no statewide license for general residential home improvement contractors. The Ohio Construction Industry Licensing Board licenses five trades: heating, ventilating and air conditioning, refrigeration, electrical, plumbing, and hydronics. Ohio Rev. Code § 4740.01 also defines the “construction project” those licenses attach to as one that excludes residential buildings, so a remodeler, roofer, or driveway paver working on a house falls outside state licensing entirely.
Three offices divide the work that follows.
- Ohio Attorney General, Consumer Protection Section. Takes complaints that a supplier used a deceptive or unconscionable practice in a consumer transaction. Home improvement work sold to a homeowner is a consumer transaction.
- The local building department. Handles permits, inspections, and code violations for the jurisdiction where the property sits. Unpermitted work, failed inspections, and construction that does not meet code are its subject matter rather than the Attorney General’s.
- Ohio Construction Industry Licensing Board. Handles the five licensed trades on non-residential projects and can act against a contractor’s license.
A homeowner with a residential complaint often files in two places at once: the Attorney General for the sales, estimate, and billing conduct, and the building department for the physical work. The two files serve different purposes later. The Attorney General’s record supports a Consumer Sales Practices Act claim; the building department’s inspection notes and violation notices document the defect itself.
Cities and counties are free to impose their own contractor registration requirements even though the state does not. Registration status, bond information, and any prior complaints are held at the local level, so the building department is also where a homeowner confirms whether the contractor was registered at all.
Filing the consumer complaint with the Attorney General
The Attorney General accepts consumer complaints through the intake linked from its file a complaint page, which opens the online complaint portal. A printable complaint form sits on the same page for consumers who prefer to mail the complaint with attachments.
Collect the transaction record
The complaint asks for the contractor’s business name and address, the dates of the transaction, the amount paid, and a description of what went wrong. Copies of the contract, the estimate, invoices, cancelled checks, and text or email exchanges attach to the complaint.
Describe the practice, not only the outcome
The Consumer Protection Section acts on conduct that Ohio’s consumer sales practices law treats as deceptive or unconscionable. A complaint that names the specific conduct, such as no written estimate offered, charges well above the estimate, or work billed but never performed, connects directly to the rules the office enforces.
Submit and keep the confirmation
The portal issues a confirmation with a complaint number. That number identifies the file in any later correspondence with the office.
Respond to the dispute resolution contact
The office forwards most consumer complaints to the business and invites a written response. This stage is informal mediation, not an order. A business that ignores the request faces no immediate penalty, but the complaint stays on file and feeds the office’s enforcement picture of that supplier.
What happens to a complaint after submission, including how individual complaints feed public enforcement actions, is covered in Ohio attorney general complaint.
The estimate rule Ohio contractors have to follow
The most frequently violated home improvement rule in Ohio is the estimate requirement in Ohio Adm. Code 109:4-3-05. Where a repair or service is expected to cost more than $25 and there has been face-to-face contact before work starts, the supplier must give the consumer a form to choose a written estimate, an oral estimate, or no estimate, and must deliver the estimate chosen before beginning the work.
The same rule caps overruns. The notice a supplier must post or hand over states that the bill will not be higher than the estimate by more than $5 or ten per cent, whichever is greater, unless the consumer approves a larger amount before repairs are finished (Ohio Adm. Code 109:4-3-05). Where an estimate was requested and the anticipated cost exceeds $50, the contractor must obtain authorization for unforeseen additional repairs costing ten per cent or more of the original figure.
Other conduct the rule labels a deceptive act includes charging for repairs the consumer never authorized, representing that repairs were made when they were not, representing that work must be done away from the residence when that is untrue, and failing to give the consumer a written itemized list of the work performed with parts and labor broken out. Each of those is a concrete allegation a complaint form can carry, and each is easier to prove than a general claim that the work was poor.
Cancelling a contract signed at your home
Contracts signed at the homeowner’s door carry their own cancellation right. Ohio Rev. Code § 1345.22 gives the buyer in a home solicitation sale until midnight of the third business day after signing to cancel, by written notice delivered to the seller by certified mail, personal delivery, fax, or email. Notice sent by certified mail is effective on the postmark date, which is why the mailing receipt matters more than the delivery receipt.
A contractor who starts tearing off a roof the same afternoon a contract was signed at the door has handed the homeowner a documented allegation that stands apart from the quality of the finished work.
Getting the money back after the complaint
Agency complaints do not produce refunds. Recovery runs through Ohio Rev. Code § 1345.09, which lets a consumer rescind the transaction or recover actual economic damages plus an amount not exceeding $5,000 in noneconomic damages. Where the practice had already been declared deceptive by an Attorney General rule, or determined to violate the statute by an Ohio court, before the transaction happened, the same section allows three times actual economic damages or $200, whichever is greater.
Small claims is the usual venue for a residential job. Ohio Rev. Code § 1925.02 limits a small claims division to money claims of $6,000 or less, exclusive of interest and costs, a figure that took effect April 9, 2025. Punitive damages fall outside small claims jurisdiction, but the section expressly preserves claims for the damages authorized by division (B) of § 1345.09. Ohio Legal Help publishes a walkthrough of how to file in small claims court covering venue and the county filing details.
A contractor who was not paid in full may answer the dispute by recording a lien against the property. The recording deadlines, affidavit contents, and service requirements are set out in Ohio mechanics lien deadlines.
Frequently asked questions
Does the Ohio Attorney General make the contractor refund my money?
No. The Consumer Protection Section forwards complaints to the business, offers informal dispute resolution, and brings enforcement actions in the state’s name against patterns of conduct. It does not enter judgments for individual consumers. A refund the business will not agree to comes from a court under Ohio Rev. Code § 1345.09, which allows rescission or actual economic damages plus up to $5,000 in noneconomic damages.
Is my contractor supposed to be licensed in Ohio?
Only in five trades. Ohio Rev. Code § 4740.01 covers heating, ventilating and air conditioning, refrigeration, electrical, plumbing, and hydronics contractors, and the “construction project” definition in that section excludes residential buildings. Cities and counties can impose their own registration requirements on residential contractors, so the local building department confirms whether a registration applied to a particular job.
What if the contractor never pulled a permit?
Permit and inspection questions belong to the building department for the jurisdiction where the property sits. That office can issue a violation notice, require correction, and order work stopped. Unpermitted work also surfaces later, at resale or on an insurance claim, so the department’s file becomes part of the permanent record on the property.
How long do I have to sue over defective contractor work?
The answer depends on the theory pleaded. Written contract claims, breach of warranty claims, and Consumer Sales Practices Act claims each run under a different section of the Revised Code, and several of them run from the date the defect was or reasonably could have been discovered rather than the date the work finished. Because the periods differ and start on different dates, the filing window for a particular job turns on the specific facts.
Can I take a contractor to small claims court in Ohio?
Yes, for money claims of $6,000 or less, exclusive of interest and costs, under Ohio Rev. Code § 1925.02. Larger claims go to the regular docket of the municipal or county court, or to common pleas. A small claims division cannot award punitive damages, though the same section preserves the damages authorized by division (B) of § 1345.09.
