Ohio to North Dakota: general contractor license reciprocity

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.
