Missouri Does Not License Home Builders
There’s no state general contractor or residential builder license in Missouri. Licensing, where it exists, is local: Kansas City, St. Louis County, Springfield and others run their own.
Missouri offers a voluntary statewide electrical contractor license that localities must recognize. Plumbing and HVAC are licensed locally.
How To Vet A Missouri Barndominium Builder
- Check local licensing and the entity. Ask whether your city or county licenses contractors, and look the business up with the Missouri 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.
- In the Ozarks, ask about karst. Sinkholes and shallow rock affect foundation and septic design.
