Builder Licensing In Wyoming Is Local
There’s no statewide residential code in Wyoming, and builder licensing, where it exists, comes from your city or county. Electrical work needs a state wiring permit from the State Fire Marshal where there’s no local program, with exemptions for owners working on their own property and for farms and ranches of 40 acres or more.
How To Vet A Wyoming Barndominium Builder
- Check local licensing and the entity. Ask your city or county what it requires, and look the business up with the Wyoming Secretary 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 wind and snow. Design wind is typically 115 mph, and Teton County mountain snow loads run 120–175 psf.
