New York Licenses Builders Locally, Not Statewide
New York has no state general contractor license. Licensing is local: New York City, Westchester, Suffolk, Nassau and other counties run their own. Electricians and plumbers are also licensed by counties or cities, not the state.
How To Vet A New York Barndominium Builder
- Check your county’s licensing and the entity. Ask your county or city what it requires, and look the business up with the New York Department of State.
- Get insurance from the agent. Ask for general liability and workers’ comp certificates sent to you directly by the insurance agent, not forwarded by the builder.
- Stand in a finished one. Ask for three completed barndominiums and visit at least one.
- Check the business. Look the company up with the Secretary of State and confirm the name matches the contract.
- Ask about snow load for your town; upstate design loads run 40–68 psf and higher in lake-effect belts.
