Contractors in Ohio | ReadyDocs Compliance

Article I · State Baseline

Licensing sets the baseline. Local offices control the job.

Municipal building departments can impose contractor registration, local bonds, insurance proof, and permit-specific requirements beyond the OCILB credential.

Ohio does not issue one statewide general-contractor license. OCILB licenses commercial electrical, HVAC, hydronics, refrigeration, and plumbing contractors, while residential and general contractor rules are usually local.

Use OCILB for state-regulated specialty trades; use the city or county permit office for local registration, permits, and inspections.

Insurance and risk

Ohio uses a state-run workers' compensation system through the Bureau of Workers' Compensation for employers with employees.
