Ohio trade license reciprocity

How local licensing works. Ohio's contractor licensing statute (R.C. Chapter 4740) covers only the individual electrical contractor license issued by OCILB and does not license tradespersons; any journeyman requirement is local. Most large cities require only that electrical work be done by or under a state-licensed contractor who has registered with the city.

Toledo. The Division of Building Inspection issues Journeyman Electrician and Residential Journeyman licenses after an examination ($100 exam fee), with proof of graduation from an apprenticeship program with 8,000 hours or an equivalent qualification (a journeyman certificate earned by testing in another city jurisdiction, completion of a recognized apprenticeship, or four years in the electrical construction industry). A Traveler Journeyman registration ($100) is available with the same documentation, and apprentices register for $25. Licenses renew annually by December 31.

Cincinnati. Contractors performing work in the city must hold a contractor registration under Municipal Code Chapter 1106 ($131.25 per year including surcharges); registration of state-licensed contractors runs until the state license expires. Toledo's application does accept a journeyman certificate obtained by testing in another city jurisdiction as a qualification to sit for (or register for) its exam.

How local licensing works. Ohio's contractor licensing statute (R.C. Chapter 4740) covers only the individual HVAC and refrigeration contractor licenses issued by OCILB and does not license tradespersons; any journeyman or technician requirement is local. Most large cities require only that HVAC work be done by or under a state-licensed contractor who has registered with the city.

Toledo. The Division of Building Inspection issues an HVAC Journeyman license after an examination ($100 exam fee) to applicants who prove graduation from an apprentice program with 5,600 hours of work experience and 576 hours of schooling, or who hold a journeyman certificate earned by testing in another city jurisdiction; a Traveler Journeyman registration ($100) is available with the same documentation, and apprentices register for $25 (state-program indenture papers attached). Applications are notarized, include an employment history and three references, and are approved by the Board of Control. Toledo also issues Refrigeration journeyman and apprentice licenses and Mechanical contractor licenses; all renew by December 31 each year.

Cincinnati. Contractors performing work in the city must hold an annual contractor registration under Municipal Code Chapter 1106 ($131.25 including surcharges); registration of state-licensed contractors runs until the state license expires. Cincinnati does not license journeyman or technician-level HVAC workers.

Hamilton. A Master Registration is required to obtain HVAC permits and covers the registrant's registered employees; no journeyman registration or exam is described.

Out-of-state holders. None of the pages reviewed publish a reciprocity path for another state's journeyman or technician license. Toledo's application does accept a journeyman certificate obtained by testing in another city jurisdiction as a qualification to sit for its exam or register as a traveler journeyman.

How local licensing works. Ohio's contractor licensing statute (R.C. Chapter 4740) covers only the individual plumbing contractor license issued by OCILB and does not license tradespersons; any journeyman requirement is local. Most jurisdictions require only that plumbing work be done by or under a state-licensed plumbing contractor who has registered locally.

Toledo. The Division of Building Inspection issues Plumbing Journeyman and Apprentice licenses (alongside Electrical, HVAC and Refrigeration journeyman licenses and Plumbing, Electrical and Mechanical contractor licenses). New journeyman applicants file the Plumbing Journeyman Exam/Apprentice Application and sit a city exam; all licenses renew by December 31 each year, and a license that lapses past the deadline requires a new application, payment and exam. Toledo's HVAC application accepts a journeyman certificate obtained by testing in another city jurisdiction for its traveler registration; Toledo's published pages do not say whether the plumbing application does the same, so ask the Division of Building Inspection (419-245-1220).

How local licensing works. Ohio has roughly 800 certified building departments, and each city, county or township decides for itself whether residential contractors are licensed, registered or left alone. A credential from one Ohio jurisdiction does not carry into the next one, and none of the jurisdictions below grants anything for a license held in another state. Use the Board of Building Standards jurisdiction map at com.ohio.gov/JurisdictionMap to find out which department has authority over a given address before applying anywhere.

Columbus. Building and Zoning Services licenses residential work under Chapter 4114 of the Columbus Building Code. A Home Improvement General Contractor license covers structural work on existing one-, two- and three-family dwellings and their accessory structures. It requires "a score of 70% or higher for 767 Ohio Home Improvement Contractor" (the ICC exam, booked through the International Code Council on (877) 783-3926), a "minimum of three (3) full years of hands-on experience in the one (1), two (2), and three (3) family home improvement field", and approval by the Board of Review of General and Home Improvement Contractors, which meets on the first Wednesday of each month and needs the notarized application at least seven days beforehand. A Home Improvement Limited Contractor license covers roofing, siding, decking, waterproofing, fencing, driveway approaches and similar specialized work and requires one full year of hands-on experience in that field plus board approval. A builder putting up new houses registers instead as a General Contractor, which covers "all permits to build new 1, 2, or 3 family, multi-family (4 or more dwelling units), and commercial structures" and needs a $25,000 bond on the city's bond form and liability insurance of at least $300,000 for damages to a single person and $500,000 per occurrence, with no exam. The 2026 fee schedule sets a $300 application fee for the board-reviewed licenses (including Home Improvement Contractor and HIC-Limited) and a $350 annual license and registration fee; a change of assignment is $100. Registrations expire at the end of the twelfth month from issuance. Building and Zoning Services, 111 North Front Street, (614) 645-7433, [email protected].

Toledo. The Division of Building Inspection licenses "contractors engaged in the business of making improvements to residential structures regulated by the Residential Code of Ohio" under Toledo Municipal Code Chapter 1313, in two tiers. A Certified Remodeling Contractor "may engage in all residential construction, alterations and renovations" and must first pass the ICC Building Contractor C examination (exam ID 767-OH-GC, delivered by Pearson VUE, nearest center in Maumee) and then the City of Toledo Certified Remodeling Exam covering Chapters 11 and 13 of the Municipal Code. A Limited Remodeling Contractor is "restricted to residential improvements such as roof and window replacement, siding application, installation of insulation, fencing, and swimming pools greater than 24 inches in depth" and sits only the city exam, which covers Chapter 13 and the 2024 International Residential Code. Both exams are open book. Applications go first to the city's Board of Control for Home Improvement and Remodeling Contractors, which decides whether the applicant may test, and the applicant must document one of four qualifications: a two-year degree in construction management, architecture or engineering; a licensed journeyman certificate in a construction trade; five years working in general building construction under a licensed remodeler, homebuilder or general contractor, evidenced by a notarized employer statement and five years of tax records; or five years self-employed on construction projects, evidenced by a notarized resume and five years of tax records. Three unrelated references and a full employment history are filed with the application. The fee is $200, of which $175 is refunded if the Board of Control finds the applicant unqualified to test. After passing, a Certificate of Compliance from the Division of Taxation is required before the license issues, and holders must carry liability insurance "in the amount of $100,000 to $300,000." Licenses renew annually and expire December 31; ten hours of continuing education are required each year. One Government Center, Suite 1600, 419-245-1220.

Cleveland. The Department of Building & Housing states that "to build or rehabilitate Cleveland homes, contractors must be bonded, insured, and registered", and that "contractors must be registered with the City of Cleveland within their trade in order to obtain permits. Separate permits are required for each separate trade, i.e. general, plumbing, HVAC, electrical, and elevator." Registration runs under Chapter 3107 of the Codified Ordinances, Registration of Contractors, which provides for both a Certificate of Registration and a Limited Certificate of Registration and sets separate qualifications for each. The city publishes a General Contractor Registration Application package in the Contractor Packages section of its construction permitting resources page; the bond amount, insurance limits and fee are set out in that package and in Chapter 3107 rather than on the department's web pages, so confirm them with Building & Housing on 216-664-2910 before filing. Registration status can be checked on 216-664-2884. Electrical, plumbing and HVAC contractors must hold the OCILB state license before the city will register them.

Cincinnati. The Department of Buildings & Inspections registers contractors under Chapter 1106 of the Municipal Code in three classes, two of which reach housing. A Home Improvement Contractor registration covers "all contractors that are involved in repair, remodeling, alteration, improvement, or addition to any building used as a private residence in one, two and three family structures." A Building Construction Contractor registration covers everything else, and expressly "include[s] contractors that engage in the construction of new one, two and three family dwellings" as well as specialties such as demolition, carpentry, masonry and glazing. The filing is the signed application, a certificate of liability insurance from an Ohio-licensed insurer with "minimum liability limits of one hundred thousand dollars ($100,000) for damages to a single person, and three hundred thousand dollars ($300,000) for one (1) occurrence", proof of Ohio workers' compensation, an assignment form naming everyone allowed to sign permit applications, and a federal tax ID or Social Security number. The fee is $125.00 plus a 3% technology surcharge, a 1% financial recovery fee and a 1% training surcharge, a total of $131.25 a year, and a registration may be bought for up to three years; same-day processing costs $208 more and mid-term changes $78. There is no exam, experience or bond requirement. An owner of a one-, two- or three-family dwelling is exempt where they personally perform the work and will occupy the home for at least a year. Working unregistered draws a $750 citation for a first offense. 805 Central Avenue, Suite 500, (513) 352-3271.

Akron and Summit County. Akron's rule is short: "the City of Akron requires all contractors regardless of trade to register as a contractor if the work they are performing requires a permit to do the work." The filing is the contractor registration application, an Akron Tax Registration Number, a certificate of liability insurance, any state licenses the trade requires, and proof of workers' compensation unless there are no employees. There is no exam and no published registration fee. The building permits themselves come from the Summit County Department of Building Standards, which in March 2024 replaced annual contractor registration with a permit-based process: "the $135 annual fee for contractors and the requirement for a $10,000 bond are now eliminated", though "contractors will still be required to provide liability insurance, State license if applicable, and a Tax ID Number." The same code change requires that property owners working on homes they do not and will not occupy have a qualified contractor take responsibility for the installations. Akron Plans & Permits, 1030 E. Tallmadge Ave., 330-375-2010; registration questions 330-375-2037. Summit County Building Standards, same address, 330-630-7280.

Dayton. The Division of Building Inspection publishes registration and bond forms only for electrical, plumbing, warm air heating and pipe-laying contractors, with separate plumbing journeyman and apprentice forms. There is no Dayton registration for a remodeler or a homebuilder as such; a residential builder pulls permits and hires or employs the registered trades. Building Inspection, 937-333-3979; One Stop Center, 371 West Second Street, second floor, 937-333-3883.

Cuyahoga County. The county created a Division of Building Standards in 2025 "with the mission of improving compliance with State of Ohio Board of Building Standards for both residential and commercial/non-residential construction within the County." It will provide contractor registration, plan review, permitting and inspections for partner communities, with registration "completed through a secure online portal" on its website; the partner community list is still being announced and an approved fee schedule is due by December 1, 2026. The county notes that it "does not offer formal endorsement, evaluation, or recommendation of any contractors or construction services" and directs residents to the state's building department look-up tool for their address.

Everywhere else. The remaining hundreds of Ohio municipalities, townships and county building departments each set their own rules, from a full licensing board to nothing beyond a permit and proof of insurance. Identify the department with jurisdiction over the address first, then ask what it registers. Whatever the local answer, the statewide obligations are the same: an OCILB license for any self-performed electrical, HVAC, refrigeration, plumbing or hydronics work, and a written contract meeting R.C. Chapter 4722 for any home construction service contract over $25,000.

How local licensing works. No Ohio agency issues a general, commercial, building or unlimited contractor license, and there is no Ohio equivalent of a qualifying party, a NASCLA route or a state business-and-law exam for builders. Ohio has around 800 certified building departments, each with its own contractor rules, so identify the department with jurisdiction over the site - the Board of Building Standards map at com.ohio.gov/JurisdictionMap does this by address - and register there before bidding. One statewide rule shapes what those departments ask for: R.C. 4740.12 provides that "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", which OCILB describes as requiring building and health departments with a registration program to demand the state license before issuing commercial permits.

Columbus. Building and Zoning Services registers a General Contractor under Chapter 4114 of the Columbus Building Code. The registration "can be associated with all permits to build new 1, 2, or 3 family, multi-family (4 or more dwelling units), and commercial structures, as well as alter or add to existing multi-family and commercial structures." The filing is a notarized application, "a Bond in the amount of $25,000" on the city's own bond form under C.C. 4114.515, and a certificate of liability insurance with "limits of liability no less than $300,000.00 for damages to a single person and $500,000.00 for one occurrence", naming Building and Zoning Services as certificate holder. There is no exam, experience, reference or financial requirement, and no board hearing - the General Contractor registration is one of the few Columbus categories that does not go before a review board. The 2026 fee schedule sets a $350 annual contractor license and registration fee, with $100 for a change of assignment or elective suspension; the registration runs to "the end of the twelfth month from the date of issuance." 111 North Front Street, (614) 645-7433, [email protected].

Cleveland. The Department of Building & Housing requires that contractors "must be bonded, insured, and registered" and that "contractors must be registered with the City of Cleveland within their trade in order to obtain permits. Separate permits are required for each separate trade, i.e. general, plumbing, HVAC, electrical, and elevator." Registration sits in Chapter 3107 of the Codified Ordinances, Registration of Contractors, which provides for a Certificate of Registration and a Limited Certificate of Registration with separate qualifications for each. A General Contractor Registration Application package is published in the Contractor Packages section of the city's construction permitting resources page, and the bond, insurance and fee figures are stated in that package and in Chapter 3107 rather than on the department's web pages - confirm them with Building & Housing on 216-664-2910 before filing. Registration status is verified on 216-664-2884, and electrical, plumbing and HVAC registrations require the OCILB state license first.

Cincinnati. Buildings & Inspections registers contractors under Chapter 1106 of the Municipal Code, and commercial builders fall in the Building Construction Contractor class, the catch-all that "will apply to all other contractors that are not addressed in the two previous descriptions" and covers specialties such as crane operations, demolition, carpentry, masonry and glazing alongside new one-, two- and three-family construction. Electrical, plumbing, HVAC, hydronic and refrigeration firms register in the separate OCILB Licensed Specialty Contractor class on their state licenses, and that city registration runs to the state license's expiry date. The filing is the signed application, liability insurance with "minimum liability limits of one hundred thousand dollars ($100,000) for damages to a single person, and three hundred thousand dollars ($300,000) for one (1) occurrence" (crane operators carry $1,000,000 per occurrence, $2,000,000 aggregate and a $4,000,000 or $10,000,000 umbrella depending on lift capacity), proof of Ohio workers' compensation, an assignment form listing everyone authorized to sign permit applications, and a federal tax ID. The fee is $125.00 plus surcharges, $131.25 a year, for up to three years; same-day processing is $208 extra. There is no exam and no bond. A company operating under more than one business name needs a separate registration for each legal entity, and where a company holds several OCILB licenses through different people, each license holder registers separately. 805 Central Avenue, Suite 500, (513) 352-3271.

Akron and Summit County. Akron requires "all contractors regardless of trade to register as a contractor if the work they are performing requires a permit to do the work", on a contractor registration application with an Akron Tax Registration Number, a certificate of liability insurance, state licenses where the trade needs one, and workers' compensation coverage unless there are no employees. No exam or fee is published. Ohio Building Code permits for Akron projects come from the Summit County Department of Building Standards, which since March 2024 has run "a permit-based process" in place of annual contractor registration: "the $135 annual fee for contractors and the requirement for a $10,000 bond are now eliminated", while "contractors will still be required to provide liability insurance, State license if applicable, and a Tax ID Number", and commercial application fees rose by $10. Akron Plans & Permits, 1030 E. Tallmadge Ave., 330-375-2010; Summit County Building Standards, same address, 330-630-7280.

Toledo. Toledo licenses Electrical, Mechanical, Plumbing, Fire, Home Improvement and Remodeling, Sign and Sidewalk contractors, plus journeymen and apprentices in the electrical, HVAC, plumbing and refrigeration trades. There is no commercial or general building contractor license, so a commercial builder in Toledo pulls permits without a city contractor credential while the trades hold theirs. All Toledo licenses renew annually and expire December 31. Division of Building Inspection, One Government Center, Suite 1600, 419-245-1220.

Dayton. The Division of Building Inspection publishes registration and bond forms only for electrical, plumbing, warm air heating and pipe-laying contractors. Dayton has no general or building contractor registration; a commercial builder works through the registered trades. Building Inspection, 937-333-3979; One Stop Center, 371 West Second Street, 937-333-3883.

Cuyahoga County. A Division of Building Standards was created in 2025 to serve partner communities with contractor registration, plan review, permitting and inspections, with registration "completed through a secure online portal" on its site. The partner community list is still being announced and "an approved fee schedule will be released by December 1, 2026", so check the state's building department look-up tool for a specific address before assuming which department has jurisdiction.

What does and does not travel. An out-of-state general contractor license, a NASCLA Accredited Examination and out-of-state project experience carry no weight in any of these jurisdictions, because none of them tests or qualifies commercial builders at all. What does matter is holding, or employing someone who holds, the OCILB license for each of the five state-licensed trades in scope, then registering that license with the city as well. OCILB's own reciprocity list is the only place an out-of-state license shortens the path, and every entry on it - Alabama, Arkansas, Kentucky, Louisiana, Mississippi, North Carolina, South Carolina, Tennessee, Texas, Virginia and West Virginia - is scoped to the electrical, HVAC, refrigeration, plumbing or hydronics trades, so those routes belong on this site's electrical, HVAC and plumbing pages rather than here.
