Workers' comp in Ohio

Ohio employers with employees must carry workers' comp through the Ohio Bureau of Workers' Compensation (BWC) or be approved to self-insure. Private carriers can't write it.

The agency in charge is the Ohio Bureau of Workers' Compensation. It can tell you whether a specific business needs coverage, and most states let you look up an employer's policy online.

Contractor licensing and insurance

We found no statewide general liability minimum tied to a general contractor license. Ohio has no statewide general contractor license. Cities and counties can set their own licensing and insurance rules, so check where the project is.

Indemnity and additional insured clauses

Ohio's anti-indemnity statute (Ohio Rev. Code Ann. § 2305.31) voids construction contract clauses that make a contractor indemnify another party for that party's own negligence, even in part. Clauses limited to the contractor's own share of fault generally hold up.

What to check on a contractor COI for a Ohio project

  1. Workers' comp. Ohio workers' comp comes only from the state fund, so a private carrier's workers' comp line on the COI doesn't cover work there. Ask for the state fund certificate, and look for stop gap employers liability, which is usually added to the general liability policy.
  2. General liability. Ohio doesn't set a statewide floor for a general contractor license, so your project requirements set the bar. Compare each limit on the COI with what the contract asks for.
  3. Additional insured. The endorsement is a separate promise from the indemnity clause, so check both. Ask for the endorsement itself, not just a box ticked on the certificate.
  4. Dates. Every policy should run through the end of the job. A COI only shows coverage on the day it was issued, so check again at each renewal.
