Do you need a general contractor license in Ohio?

State law and licensing-board sources · Last reviewed October 11, 2026

Journeyman level Licensed by cities or counties, not the state What's a journeyman?

Ohio has no statewide general contractor license. The state's licensing board, OCILB, licenses only five trades: electrical, HVAC, hydronics, plumbing and refrigeration contractors. General contractors answer to cities instead: Columbus, for example, registers general contractors and licenses home improvement contractors. If your work includes one of the five licensed trades, that contractor license comes from the state. [1][2][3]

New to the trade?

Starting from zero in Ohio

Ohio has no state general contractor license and no state card for construction workers, so you start by getting hired by a builder or applying to a registered carpentry apprenticeship. The Central Midwest Regional Council of Carpenters runs union apprenticeships with Ohio training centers, and ApprenticeOhio lists registered programs; you apply to a program just like applying for a job. [1][6][7][8]

  • High school diploma or GED

    No state rule, because Ohio doesn't license general building work. Programs set their own: the Central Midwest Regional Council of Carpenters lists age 17 and passing a substance abuse test as its requirements and asks you to bring any high school, GED or college transcripts Its FAQ doesn't list a diploma requirement. Ask any other program or employer what it requires. [1][6]

  • Minimum age

    Ohio's apprenticeship law defines an apprentice as at least 16. The carpenters' council takes applicants at 17. [6][9]

  • Drug test and ID

    The carpenters' council requires a substance abuse test and a state or government photo ID Ohio applicants also bring a copy of their birth certificate, and veterans their DD214. [6]

  • Cost and classes

    Carpenter apprentices pay no tuition Costs are hand tools, books (about $100 a year) and union dues. You attend one week (40 hours) of class every three months, 160 hours a year, and work at least 1,300 hours a year for a union contractor over the four-year program. [6]

  • Pay while you learn

    ApprenticeOhio says registered apprentices are full-time employees from day one, with pay increases as they progress. The carpenters' council says missed classes or work hours delay its six-month to one-year raises. [6][8]

  • Credit for school or military

    Ohio graduates of the carpenters' apprenticeship receive 30 college credits from Cuyahoga Community College. Many veterans can use GI Bill benefits during a registered apprenticeship. [6][8]

  • Trade work needs a state license

    If you plan to contract for electrical, HVAC, plumbing, hydronics or refrigeration work, that needs an OCILB contractor license, which takes five years in that trade. [2][4]

  • Still in high school?

    Registered apprenticeships can start at 16, and ApprenticeOhio says Ohio has more than 100 pre-apprenticeship programs for youth ages 16 to 20, where high school students work part-time while meeting graduation requirements. The state's high school Construction Technologies career field has a structural pathway with courses such as Carpentry and Masonry Technical Skills and Construction Pre-Apprenticeship. Through College Credit Plus, students in grades 9 to 12 can take college courses for high school and college credit. Because there's no state general contractor license, there are no state license hours for school to count toward. [1][9][10][11][12][13][14]

The license pathway in Ohio

  1. 1

    City contractor license or registration

    Ohio has no state general contractor license, so there's no state ladder to climb. Cities set their own rules. Columbus registers general contractors and separately licenses home improvement contractors, who need three years of experience and an exam. Check with the building department in each city where you'll work. [1][3]

Ohio has no state general contractor license

Ohio's contractor licensing law defines a "license" as one the Ohio Construction Industry Licensing Board (OCILB) issues to a heating, ventilating and air conditioning contractor, refrigeration contractor, electrical contractor, plumbing contractor or hydronics contractor. General contractors, builders and remodelers aren't on that list.

OCILB "issues State Licenses to Commercial Contractors" in those five trades only, so general contracting is left to cities and other local governments. [1][2]

The trades Ohio does license

If you plan to contract for this work yourself, or want to know who you'll hire, the state licenses these contractors through OCILB:

Each license takes five years as a tradesperson in that trade, two exams and at least $500,000 in liability insurance. The state license covers commercial work, and OCILB says local building departments may require it for residential work. [2][4]

City rules: Columbus

Columbus Building and Zoning Services licenses and registers contractors under Chapter 4114 of the city code. All contractors working in the city must get "the appropriate license or registration before they can apply for permits and begin the job."

General contractor. You need a completed, notarized application, a $25,000 bond on the city's form, and a certificate of liability insurance from an insurer licensed in Ohio. Columbus doesn't require board approval for general contractors. A registered general contractor can build new structures and do structural work on commercial buildings and on multi-family buildings (4 or more units). On 1-, 2- and 3-family homes, a general contractor can only coordinate the work and must subcontract it to city-licensed contractors.

Home improvement general contractor. To do structural work on existing 1-, 2- and 3-family homes, including garages and accessory buildings, you need this license instead. It requires at least three full years of "hands-on" home improvement experience, a score of 70% or higher on the International Code Council's 767 Ohio Home Improvement Contractor exam (taken through Pearson VUE), and approval by the city's Board of General and Home Improvement Contractors.

Fees are on the city's Building and Zoning Services fee schedule. Contact Building and Zoning Services at (614) 645-7433. [3]

Other Ohio cities

Other cities set their own rules, and some suburbs differ from the city next door. Cleveland, for example, registers contractors through its Department of Building & Housing, and electrical, plumbing and HVAC contractors must hold the state license before they register. Before you bid a job, call the building department of the city where it is. [5]

Steps to get licensed in Ohio

  1. Confirm you don't need a state license for your work

    General building work needs no state license in Ohio. But if you'll contract for electrical, HVAC, plumbing, hydronics or refrigeration work, you need that OCILB contractor license. [1][2]

  2. Check each city where you'll work

    Contact the building department in each city. In Columbus, all contractors must get the right city license or registration before they can apply for permits. [3]

  3. Meet the city's conditions

    Expect forms, fees, a bond and insurance. A Columbus general contractor needs a notarized application, a $25,000 bond and a certificate of liability insurance; a Columbus home improvement contractor also needs three years of experience and a passing ICC exam. [3]

  4. Use licensed trade contractors

    In Columbus, a general contractor managing work on 1-, 2- and 3-family homes must subcontract it to city-licensed home improvement, mechanical, electrical and plumbing contractors. [3]

Not from the state. Ohio's contractor licenses cover only electrical, HVAC, hydronics, plumbing and refrigeration contractors. Cities set their own rules: Columbus, for example, registers general contractors and licenses home improvement contractors. [1][2][3]

What does Columbus require of a general contractor?

A notarized application, a $25,000 bond and a certificate of liability insurance. There's no board approval or exam for general contractors, but structural work on existing 1-, 2- and 3-family homes needs a separate home improvement contractor license. [3]

Is there a test for a home improvement contractor license in Columbus?
