Tennessee Licenses Builders On Larger Jobs
Tennessee requires a contractor license for projects of $25,000 or more, issued by the Tennessee Board for Licensing Contractors. A barndominium clears that easily, so your builder should be licensed.
Tennessee licenses also carry a monetary limit, the largest job the contractor is approved for. Check that the limit covers your project, not just that a license exists.
How To Vet A Tennessee Barndominium Builder
- Look up the license with the Tennessee Department of Commerce and Insurance. Confirm it’s active, residential, and that the monetary limit covers your contract.
- 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.
- In West Tennessee, ask about seismic design. The New Madrid zone adds foundation and connection requirements.
