Ohio General Contractor License: County, City & Township Rules (No State Board)

Ohio does not issue a statewide general contractor license — any licensing is local, and city, county and township rules differ. Who actually licenses general contractors and where to check, verified from official sources.

Source-verified

Requirements below are drawn from No Ohio state board licenses general contractors. General and residential contractors are regulated by local (city, county, township) building departments. The Ohio Construction Industry Licensing Board (OCILB), in the Ohio Department of Commerce Division of Industrial Compliance, licenses only five commercial specialty trades - electrical, HVAC, hydronics, plumbing and refrigeration - and does not issue a general contractor license. (official site) and last verified August 5, 2026. Boards change fees and rules often — confirm before acting.

Requirements at a glance

State general contractor license: None. Ohio does not license general contractors or residential contractors at the state level. The Ohio Department of Commerce states plainly on its Verifying Licensed Contractors page: "Note: residential contractors are not required to be licensed in Ohio."
Who regulates general construction instead: Local building departments. Commerce directs consumers to ask the county, city or township building department. Requirements vary by jurisdiction and are not published in one statewide list.
Statewide rules that apply with no license at all - ORC Chapter 4722 (home construction service): Ohio Revised Code Chapter 4722 creates no license, no registration and nothing to apply for - but it binds Ohio residential contractors statewide. The duties attach to a "home construction service supplier", defined in ORC 4722.01(D) as "a person who contracts with an owner to provide home construction services for compensation and who maintains in force a general liability insurance policy in an amount of not less than two hundred fifty thousand dollars"; "home construction service" is the construction, repair, improvement, remodel or renovation of a one-, two- or three-family dwelling and accessory construction incidental to it, excluding industrialized units, manufactured homes and mobile homes; it does not reach a structure of four or more dwelling units except work on an individual unit, or condominium common areas (ORC 4722.01(B), (F)). WRITTEN CONTRACT AT $25,000 - ORC 4722.02(A): "no home construction service supplier shall perform any home construction service the cost of which equals or exceeds twenty-five thousand dollars unless the supplier enters into a written home construction services contract with the owner", and that contract must carry nine listed terms, among them the supplier's taxpayer identification number, the anticipated start and completion dates, the total estimated cost, "a copy of the supplier's certificate of insurance showing general liability coverage in an amount of not less than two hundred fifty thousand dollars" and the dated signatures of both parties. Unforeseen excess costs above $5,000 over the life of the contract require advance notice of a written or oral estimate, per the owner's election (ORC 4722.02(B)(1)-(2)) - unless the contract fixes a firm price with no excess charges (ORC 4722.02(B)(3)); cost-plus contracts are excepted from both duties (ORC 4722.02(C)). DOWN PAYMENT CAP - ORC 4722.04: a supplier "may take as a down payment not more than ten per cent of the contract price before the supplier's performance that is required by the contract begins", except up to seventy-five per cent of a special-order item that is otherwise not returnable or usable; the section does not apply to a cost-plus contract. PROHIBITED ACTS - ORC 4722.03(A) lists eleven, including starting work without the required written contract, charging unapproved excess costs, and failure to "perform the home construction service in a workmanlike manner", a phrase ORC 4722.01(G) ties to "the minimum quantifiable standards promulgated by the Ohio home builders association". ENFORCEMENT - the Ohio Attorney General may investigate and may "administer oaths, subpoena witnesses, adduce evidence, and require the production of relevant matter" (ORC 4722.06(A)-(B)), bring injunction and class actions with civil penalties (ORC 4722.07), and an owner has a private cause of action under ORC 4722.08. None of this is a credential: Chapter 4722 contains no licensing or registration provision anywhere, so there is no state list of home construction service suppliers to join and nothing to file with the Attorney General.
When a state license IS required: When a contractor performs commercial (non-residential) work in one of the five OCILB trades - electrical, HVAC, plumbing, hydronics or refrigeration. ORC 4740.13(A): "No person shall act as or claim to be a type of contractor that this chapter licenses unless that person holds or has been assigned a license issued pursuant to this chapter for the type of contractor that person is acting as or claiming to be."
Limit on local registration schemes: ORC 4740.12(A): "No political subdivision, district, or agency of the state may adopt an ordinance or rule that requires contractor registration and the assessment of a registration or license fee unless that ordinance or rule also requires any contractor who registers and pays the registration or license fee to be licensed in the contractor's trade pursuant to this chapter." Read that with the chapter's own defined terms, which are narrower than the sentence sounds. "Contractor" is defined in ORC 4740.01(B) by responsibility for construction "on a construction project", and ORC 4740.01(F) defines a "construction project" as one "involving a building or structure subject to Chapter 3781. of the Revised Code and the rules adopted under that chapter, but not an industrialized unit or a residential building as defined in section 3781.06 of the Revised Code" - so one-, two- and three-family dwellings (ORC 3781.06(C)(9)) sit outside it. The companion municipal statute is drawn the same way: ORC 715.27(H) defines "specialty contractor" as "a heating, ventilating, and air conditioning contractor, refrigeration contractor, electrical contractor, plumbing contractor, or hydronics contractor", and ORC 715.27(A)(3) lets a municipal corporation provide for licensing "house movers; plumbers; sewer tappers; vault cleaners; and specialty contractors who are not required to hold a valid license issued pursuant to Chapter 4740. of the Revised Code". In practice Columbus, Cleveland, Cincinnati and Toledo all require a general-contractor or building-contractor registration under live ordinances (see below), and Toledo's chapter prices its license - T.M.C. 1313.05(d): "If the licensee has more than one place of business, a separate license shall be necessary for each location. Each license shall cost the same as the first ($140)...". Nothing in the statute, in the OCILB's own pages, or in the local ordinances and application forms cited here reconciles the two, so this page states each as written and does not resolve the tension - confirm with the building department that will issue your permit. ORC 4740.12(B) preserves local authority to regulate the five trade systems and to register tradespersons.
Insurance (OCILB trade license): OAC 4101:16-2-09(D) requires a licensee to "maintain contractor's liability insurance in the individual's name including, without limitation, complete operations coverage in an amount of at least five hundred thousand dollars"; where the license has been assigned to a business entity the policy must be in that entity's name, and "the business entity must be registered with the Ohio secretary of state to do business in Ohio" (see also ORC 4740.06(B)(4)). OCILB puts the same rule this way: "you are responsible for maintaining at least $500,000 in liability coverage, and your insurance must be in a single contracting company name."
License assignment (OCILB trade license): The license is issued to the individual but must be assigned to a contracting company; if unassigned, the specialty section places it in inactive status (ORC 4740.07(A)-(B)). One company name only, no DBAs. Non-transferable.
Workers under the license (OCILB trade license): All tradespeople must be W-2 employees of the company or hired through a nationally recognized temporary agency. Workers paid by 1099 are independent contractors and must hold their own state license for the trade. ORC 4740.131 permits leased employees from a PEO, AEO or temporary agency under direct supervision.
Who the local registration is issued to - it differs by jurisdiction, and two large counties have no standing general-contractor registration (Franklin County says so for its unincorporated area; Summit County moved the paperwork to permit time): Ohio's local schemes do not agree on who holds the credential, so there is no statewide answer. ISSUED TO A NAMED INDIVIDUAL: Columbus City Code 4114.933(A) - "A special inspector's registration, demolition contractor's registration, and a general contractor's registration, shall be issued in the name of the registrant who successfully met the qualifications as required by this chapter. However, said registrant, at the time of applying for such registration, or at any time thereafter, may assign, the rights of a registration to a business concern with whom the registrant is associated as a legal, full-time officer, proprietor, partner, or employee"; the registration "shall become null and void 90 calendar days after such disassociation". Toledo Municipal Code 1313.03(a)(1) grants its Certified Remodeler's License "to an individual who demonstrates his knowledge of and experience in construction and remodeling structures", and 1313.05(a): "No license shall be assignable or transferable. However, a licensee may use his license in another company providing he has an ownership position in that company..." ISSUED TO THE CONTRACTING ENTITY: Cleveland Codified Ordinances 3107.01(c) - a Certificate of Registration is issued "to a Contractor", defined in 3107.01(d) as "any individual, firm, co-partnership, corporation, association or other organization" - with 3107.07(c) requiring that "When an applicant for a Certificate of Registration is a firm or corporation, at least one (1) member of that firm or corporation, shall individually be qualified for registration". Cincinnati Building Code 1106-9: "No person or entity shall undertake or perform work requiring a permit of a registered building construction contractor... without first obtaining a building construction contractor registration". NO GENERAL-CONTRACTOR REGISTRATION - BUT READ THE SCOPE: Franklin County's answer covers its unincorporated area only - "You do not need a Contractor's License to obtain a structural building permit to work in unincorporated Franklin County, however to perform electrical, heating, or plumbing work you must possess a valid license." Summit County abolished the standing annual registration but moved the paperwork to permit time - "Do I need to register as a contractor? No, not as previously required. Registration is a permit basis only. When applying for a permit, include your Certificate of Insurance (COI), Federal ID number and if applicable, your State License with each application." EMPLOYEES: in none of these jurisdictions does an employed general-construction worker need a credential of their own - Toledo states it outright at 1313.03(e), "No license shall be required by any workman who is under contract to, or employed by, a licensee", and Columbus's individual registration is expressly assigned to and operated through the business concern. These six jurisdictions are a sample, not a census: Ohio has no statewide list of local requirements, so confirm with the building department that will issue your permit.

Legal basis

Ohio does not license general contractors at the state level.

Ohio issues no state general contractor or residential contractor license. The Ohio Department of Commerce says so on its Verifying Licensed Contractors page: “Note: residential contractors are not required to be licensed in Ohio”, and in its OCILB news release: “While residential contractors are not required to be licensed by the state, local building departments throughout Ohio may have their own verification or licensing requirements.” The Ohio Attorney General states the same from the consumer side: “State law does not require home improvement contractors to be licensed, but many Ohio cities do.” Under ORC 4740.01(D) the only “licensed trades” are HVAC, refrigeration, electrical, plumbing and hydronics; ORC 4740.13(A) forbids acting only as “a type of contractor that this chapter licenses”, so contracting outside those five trades requires no OCILB license. ORC 4740.01(F) further excludes residential buildings from the definition of a “construction project”, and ORC 3781.06(C)(9) defines a residential building as a one-, two- or three-family dwelling house and accessory structures. No state license is not the same as no state law, though: ORC Chapter 4722 imposes written-contract, down-payment and conduct duties on home construction service suppliers statewide without creating any license or registration.

What it’s called

There is no Ohio general contractor license; the phrase “Ohio contractor license” in practice refers to the OCILB state commercial trade license. OCILB: “Licenses issued by the Board are Contractor Licenses and also referred to as Master Licenses.” Also called the OCILB commercial contractor license. ORC Chapter 4740 is referred to by OCILB as “The Ohio Contractor Licensing Law.” At the local level the equivalent is typically a contractor registration issued by a city, county or township building department.

Who does NOT need a license — exemptions

This is the core of Ohio’s answer. (1) General contractors and residential contractors need no state license at all - Ohio Department of Commerce, Verifying Licensed Contractors: “Note: residential contractors are not required to be licensed in Ohio” and “While residential contractors are not required to be licensed by the state, local building departments throughout Ohio may have their own verification or licensing requirements.” No state license, however, does not mean no statewide duty: ORC Chapter 4722 imposes written-contract, down-payment and conduct rules on home construction service suppliers without licensing anyone (see the requirements above). (2) Any contracting work outside the five licensed trades is outside OCILB entirely: ORC 4740.01(D) defines “licensed trade” as only work performed by an HVAC, refrigeration, electrical, plumbing or hydronics contractor, and ORC 4740.13(A) prohibits only acting as “a type of contractor that this chapter licenses.” (3) Residential work is excluded by definition: ORC 4740.01(F) defines “construction project” as one “involving a building or structure subject to Chapter 3781. of the Revised Code and the rules adopted under that chapter, but not an industrialized unit or a residential building as defined in section 3781.06 of the Revised Code” - and ORC 3781.06(C)(9) defines “residential building” as “a one-family, two-family, or three-family dwelling house, and any accessory structure incidental to that dwelling house.” A local building or health department may nonetheless require the state commercial license for residential contractors in its jurisdiction. (4) Low-voltage exemption - ORC 4740.13(D): “A person is not an electrical contractor subject to licensure under this chapter for work that is limited to the construction, improvement, renovation, repair, testing, or maintenance of the following systems using less than fifty volts of electricity: fire alarm or burglar alarm, cabling, tele-data sound, communication, and landscape lighting and irrigation.” (5) ORC 4740.13(C): a licensed contractor may install, service and maintain related control wiring for equipment tied to their license, provided the control wiring is less than 25 volts. (6) Tradespersons - defined in ORC 4740.01(E) as individuals employed by a contractor who do not assume responsibility for the means, method or manner of the work - do not need a contractor license; they work under the licensee’s license but must be W-2 employees or supplied through a nationally recognized temporary agency. (7) Reciprocity - ORC 4740.08 allows a license without examination under a written reciprocity agreement; OCILB lists agreements with Alabama, Arkansas, Kentucky, Louisiana, Mississippi, North Carolina, South Carolina, Tennessee, West Virginia, Virginia and Texas for various trades. (8) Inactive (escrow) status - a licensee in inactive status is exempt from continuing education and need not maintain liability insurance while inactive, but must still renew annually and may not perform work requiring the license (OAC 4101:16-2-12(B)-(D)). (9) ORC 4740.06(K): an OCILB license does not limit any requirement of, or license issued by, the Ohio Fire Marshal.

Where to get licensed

Local building departments. The Ohio Department of Commerce directs consumers to “Ask your county, city or township building department to verify that the contractor is licensed or registered to work in your area and ask if permits are required for the specific work being completed.” Residential-contractor complaints go to the Ohio Attorney General’s Consumer Protection Section (1-800-282-0515) and/or the local building department. Requirements vary by jurisdiction and are not published in any single statewide list. Note the statutory limit on local schemes - ORC 4740.12(A): “No political subdivision, district, or agency of the state may adopt an ordinance or rule that requires contractor registration and the assessment of a registration or license fee unless that ordinance or rule also requires any contractor who registers and pays the registration or license fee to be licensed in the contractor’s trade pursuant to this chapter.” That sentence has to be read with the chapter’s own defined terms, which are narrower than it sounds, and with the local registrations several Ohio cities do require - see “Limit on local registration schemes” in the requirements below.

Verify a license in Ohio

Ohio Department of Commerce, Division of Industrial Compliance / Ohio Construction Industry Licensing Board publishes a public license search , searchable by License Type, Credential Number, First Name, Last Name, Maiden Name, State or County. It covers individual OCILB licensees in the five commercial specialty trades only - electrical, HVAC, hydronics, plumbing and refrigeration. It does NOT cover general contractors or residential contractors, who hold no state credential.

Records come from Ohio Department of Commerce, Division of Industrial Compliance / Ohio Construction Industry Licensing Board’s own system. LicensingAtlas does not hold license records and cannot confirm any individual’s status — the date on this page refers to the requirements described above, not to anyone’s credential.

Frequently asked questions

Does Ohio license general contractors at the state level?

No. Ohio does not issue a statewide individual general contractor license; licensing is handled locally — by city, county and township building departments — and the requirements differ between them; some jurisdictions require none at all.

How do I find the right general contractor licensing authority in Ohio?

Because there is no statewide license, check the building or licensing department of the specific city or county where you will work — the section above lists Ohio’s relevant authorities and official links.
