Workers' comp in Idaho
Idaho employers with one or more full-time, part-time, seasonal or occasional employees must carry workers' comp before the first hire.
The agency in charge is the Idaho Industrial Commission. 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
Idaho contractor registration requires general liability, including products and completed operations, of at least $300,000 single limit, plus proof of workers' comp or a statement of why it isn't required.
Indemnity and additional insured clauses
Idaho's anti-indemnity statute (Idaho Code § 29-114) voids construction contract clauses that make a contractor indemnify another party for that party's sole negligence. Clauses that cover shared fault are generally allowed.
What to check on a contractor COI for a Idaho project
- Workers' comp. Nearly every contractor with employees needs it in Idaho. A contractor with a crew and no workers' comp on its COI is a gap. For an out-of-state contractor, confirm Idaho is listed on the workers' comp policy.
- General liability. A Idaho license only shows the contractor met the state's floor. Compare each limit on the COI with your project requirements, which are usually higher.
- 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.
- 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.
Forsured checks every contractor COI against your project requirements, then keeps checking for the life of the project. Send us one project's requirements and a contractor COI or two for a free COI risk check.
