Ohio Contractor License & Insurance Requirements

Ohio licenses commercial trades — electrical, plumbing, HVAC, hydronics, refrigeration — at the state level via OCILB. There is no statewide GC license. Cities (Columbus, Cleveland, Cincinnati) license GCs at the local level. Residential work is largely unlicensed at state level.

License threshold
Trade-specific (OCILB). Cities: typically any building-permit work.
WC trigger
All employers — Ohio is a monopoly-state-fund WC state (BWC).
Bond
OCILB trades: $25K bond. No statewide GC bond.
License authority: Ohio Construction Industry Licensing Board (OCILB) — for trades; no statewide GC license license verification portal.

Workers' comp posture

Ohio is one of four monopoly-state-fund states. Workers' comp is purchased exclusively from the Ohio Bureau of Workers' Compensation (BWC). Out-of-state subs need either BWC coverage or a BWC certificate of extraterritoriality. Stop-Gap Employer's Liability is added by endorsement to the GL policy.

Common public-bid insurance minimums

These are limits commonly required on OH public-works prequalification. They are NOT a state-mandated minimum — verify against your specific procurement spec or contract.

General Liability
$1M per occurrence / $2M aggregate (typical ODOT + state-university spec)
Workers' Comp
BWC coverage; $500K-$1M Stop-Gap EL on the GL policy
Auto Liability
$1M combined single limit

Ohio state-specific quirks

3 pitfalls every OH GC misses

Out-of-state WC policy

Like Washington, an out-of-state sub's WC policy does NOT cover Ohio work. Either BWC coverage or extraterritoriality. Stop-Gap on the GL handles EL.

Missing Stop-Gap endorsement

Because BWC doesn't write EL, the GL policy needs a Stop-Gap endorsement. Most out-of-state COIs miss this.

Residential vs commercial OCILB scope

OCILB licenses commercial trades only. A residential remodeler may legitimately have no state license — verify city-level rules.

Frequently asked questions

Does Ohio require a state GC license?

No. Ohio licenses commercial trades (electrical, plumbing, HVAC, hydronics, refrigeration) at state level via OCILB. There is no statewide GC license. Cities license GCs locally.

Why is Ohio workers' comp different?

Ohio is one of four 'monopoly-fund' states. WC must be purchased from the Ohio BWC (or self-insurance). Private WC insurers cannot write WC in OH. Employer's Liability is handled via Stop-Gap on the GL policy.

How do I verify an Ohio contractor license?

Use the eLicense Ohio search at elicense.ohio.gov/oh_communitieslookup for OCILB trade licenses. For city GC licenses (Columbus, Cleveland, Cincinnati) use the city Building Department portal.

What is Stop-Gap Employer's Liability in Ohio?

An endorsement to the GL policy that provides EL coverage for monopoly-state-fund states (OH, WA, ND, WY). Required because the BWC WC policy does not carry EL.

Can an out-of-state sub bring their existing WC policy to Ohio?

Generally no. They must obtain BWC coverage for the OH exposure or qualify for extraterritoriality. Stop-Gap on their GL handles the EL piece.
