The state file is the first pass: licensing authority, reciprocity posture, workers' compensation threshold, bond notes, and renewal rules. It should not be treated as the final filing answer for a job site.
Municipal building departments can impose contractor registration, local bonds, insurance proof, and permit-specific requirements beyond the OCILB credential.
Use OCILB for state-regulated specialty trades; use the city or county permit office for local registration, permits, and inspections.
Primary licensing body
Ohio Construction Industry Licensing Board; local building departments is the main statewide reference point for this file. County and municipal departments may still impose separate registration, permit, insurance, inspection, or bond requirements.
