3. Check that the license is current and in good standing -- not expired, suspended, or revoked.

6. Request a copy of the contractor's insurance certificate and verify it is current.

Hiring an unlicensed contractor in Colorado carries significant risks for both the homeowner and the contractor:

• No consumer protections: State recovery funds and guaranty programs typically only cover work performed by licensed contractors.
• Insurance issues: Your homeowner's insurance may deny claims related to work done by an unlicensed contractor.
• Permit problems: Building permits often require a valid contractor license. Work done without permits can create issues when selling your property.
• Quality concerns: Licensed contractors have demonstrated minimum competency through exams, experience requirements, or both.
• Legal liability: Homeowners may bear greater legal responsibility for injuries or property damage caused during unlicensed work.

Colorado does not currently have reciprocal contractor licensing agreements with other states. Contractors licensed in other states must apply for a new Colorado license through the standard application process. Some states may credit out-of-state experience toward licensing requirements -- contact the Colorado Department of Regulatory Agencies (DORA) for details.
