Quick answer: Ohio's Construction Industry Licensing Board (OCILB) issues state licenses only for commercial electrical, HVAC, plumbing, hydronics & refrigeration contractors. There is no state license for general contractors, roofers, painters, carpenters, landscapers, or handymen, and residential work in every trade is licensed or registered at the local (city/county) level, so requirements vary by jurisdiction.
In Ohio, whether you need a license depends on both the trade and whether the job is commercial or residential.
Which trades need a license in Ohio?
| Trade | State license required? | Licensing body |
|---|---|---|
| Plumber | State + Local | Commercial plumbing contractors must hold a state OCILB plumbing (master) license, earned by 5 years of trade experience plus passing the PSI exam. Residential plumbing is regulated locally: cities such as Columbus, Cincinnati and Cleveland require contractor registration and often require the state license or a local journeyperson credential to pull permits. Confirm rules with the local building department. |
| Electrician | State + Local | Commercial electrical contractors need a state OCILB electrical license (5 years' experience plus PSI exam). Residential electrical work is governed by local building departments; Cleveland and Cincinnati require electrical contractors to be state-licensed and locally registered. Verify with your municipality. |
| HVAC | State + Local | Commercial HVAC (and refrigeration) contractors must hold a state OCILB HVAC license via the same 5-year experience and PSI exam path. Residential HVAC is handled by local building departments, which frequently require the state license plus city registration to obtain permits. |
| General Contractor | Local | Ohio has no statewide general contractor license. Requirements are set locally: for example, Columbus registers general contractors and requires a $25,000 bond, and Cincinnati and Cleveland require contractor registration (bonded and insured) before work begins. Check the city or county building department where you work. |
| Roofer | Local | There is no Ohio state roofing license (a bill to license commercial roofers has been proposed but is not law). Roofers are handled through local contractor registration and permitting; many cities require registration, bonding and insurance. Confirm locally. |
| Painter | No state license | Ohio does not license painters at the state level. Some municipalities may require general contractor or home-improvement registration for paid work, and lead-paint (RRP) rules apply to pre-1978 housing, so check local requirements. |
| Carpenter | No state license | Ohio has no state carpentry license. Carpentry falls under local building permits and, where applicable, city general-contractor or home-improvement registration. Requirements vary by jurisdiction. |
| Landscaper | No state license | General landscaping is not licensed by the state of Ohio. Note that some specialty activities (such as commercial pesticide application) are separately regulated by the Ohio Department of Agriculture, and local registration may apply for hardscaping/construction work. |
| Handyman | No state license | Ohio has no state handyman license. A handyman may still need local home-improvement or contractor registration and cannot perform work reserved for licensed trades (commercial electrical, HVAC, plumbing, hydronics, refrigeration). Cincinnati, for instance, exempts owner-occupants of 1-3 family homes but requires most paid contractors to register. |
| Cleaner | No license | Residential and commercial cleaning services are not a licensed construction trade in Ohio and need no state or trade license, though standard local business registration and tax rules apply. |
Statuses reflect state-level rules; local city/county building departments frequently add registration, bonding, or licensing requirements—especially for residential work.
State commercial licensing vs. local residential rules
Ohio splits construction licensing between the state and local governments. The Ohio Construction Industry Licensing Board (OCILB), part of the Department of Commerce's Division of Industrial Compliance, issues state licenses to commercial contractors in five specialty trades. Residential work in those same trades—and virtually all other trades—is regulated by local building and health departments. Under Ohio's contractor licensing law, permitting authorities must verify a state license before issuing commercial permits, and localities may also require the state commercial license for residential jobs. Always confirm requirements with the city or county where the work is performed.
The five OCILB state-licensed trades
OCILB issues Contractor (master) licenses for electrical, HVAC (heating, ventilating & air conditioning), plumbing, hydronics, and refrigeration contractors. Applicants must have worked in the trade for at least five years immediately before applying and must pass the PSI licensing examination. These are the only construction trades licensed at the Ohio state level, and the board regulates commercial contractors performing this work. You can verify any license through the OCILB eLicense Center.
Trades with no Ohio state license
Ohio does not issue a state license for general contractors, roofers, painters, carpenters, landscapers, or handymen. This does not mean the work is unregulated—local building departments commonly require contractor or home-improvement registration, bonding, insurance, and permits. A proposal to license commercial roofers statewide has been introduced in the legislature but is not currently law.
Local requirements in major Ohio cities
Because residential and general work is regulated locally, requirements differ by city. Columbus registers contractors, requires OCILB-licensed trades to submit their state license, and requires a $25,000 bond, with separate local credentials such as journeyperson plumber and home-improvement contractor. Cincinnati requires nearly all contractors to register annually and requires plumbers, electricians and HVAC/mechanical contractors to also hold their OCILB state license, while exempting owner-occupants of 1-3 family homes. Cleveland requires contractors to be bonded, insured and registered, and requires electrical, plumbing and HVAC contractors to first be licensed by the State of Ohio, with separate permits per trade. Always check the local building department before bidding or pulling permits.
How to get licensed in Ohio
- Determine whether your work is commercial or residential and identify the exact trade, since state licensing (OCILB) applies only to commercial electrical, HVAC, plumbing, hydronics, and refrigeration work.
- If your trade is OCILB-licensed, document at least five years of trade experience and register for and pass the PSI licensing examination, then apply through the OCILB for your state contractor (master) license.
- For general contracting, roofing, painting, carpentry, landscaping, or handyman work, contact the city or county building department where the job is located to learn local registration, bonding, and insurance requirements.
- Register with each local jurisdiction as required (e.g., Columbus, Cincinnati, or Cleveland), providing your OCILB state license number, bond, and proof of insurance where applicable.
- Verify any license or registration through the OCILB eLicense Center and pull the required trade-specific permits before starting work.
