How To Vet A South Carolina Barndominium Builder
- Look up the license through SC LLR and confirm it’s an active residential builder license under the contract name.
- 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.
- On the coast, ask about wind-borne debris protection for windows and doors, which the code requires in that region.
