Colorado splits contractor licensing between the state and local governments, which confuses a lot of homeowners. Here's the short version.
Licensed by the state
- Plumbers and electricians are licensed through DORA (the Colorado Department of Regulatory Agencies). You can look up a license online before work starts.
- Household movers and towing carriers are regulated by the Public Utilities Commission.
- Commercial pest control applicators are licensed by the Colorado Department of Agriculture.
Licensed or registered locally
General contractors and roofers are not licensed statewide in Colorado. Many cities and counties require their own license or registration, so ask for the one that matches your address.
Five checks before you sign
- Verify the license or registration.
- Ask for proof of insurance.
- Get a written scope and price.
- Tie payments to finished work, not dates.
- Ask who pulls the permit.
