Colorado Licenses The Trades, Not The Builder
Colorado’s state boards license electricians and plumbers. General contractor licensing, where it exists, is run by cities and counties, so ask your building department what applies to your site.
How To Vet A Colorado Barndominium Builder
- Check the trades and local license. Look up the electrician and plumber with DORA, and ask your city or county whether it licenses contractors.
- 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 soils and snow. Swelling soils under the Front Range need an engineered foundation, and mountain snow loads can exceed 100 psf.
