Colorado - 2026 Contractor License Requirements
Official Colorado contractor license lookup information, agency details, and homeowner notes for verifying a contractor before hiring.
Official agency
Department of Regulatory Agencies (DORA)
Colorado does not use one broad statewide GC board like CA; this is the main state license lookup starting point. Local contractor licensing still matters.
Visit official lookupAbout Colorado contractor licensing
Colorado does not have a single statewide general contractor license the way California or Arizona does. The Department of Regulatory Agencies is the right state starting point for regulated trades, but homeowners often also need to verify city or county licensing, especially in metro areas where local permitting and contractor rules are more developed.
How licensing works in Colorado
Colorado's system is mixed. The state regulates certain professions and trades through DORA, but broad general contractor licensing is commonly handled by local jurisdictions. That means a contractor may need local approval in Denver, Colorado Springs, Fort Collins, or another city even though there is no universal statewide GC card to check. For homeowners, the practical rule is to verify state-regulated trades first, then confirm local contractor licensing wherever the property sits.
What to verify in Colorado
Start with the DORA license search for any state-regulated trade involved in the project. Then check the local building department or contractor licensing office for the city or county where the home is located, because that is often where general contractor approval lives. Confirm the license or registration is active, issued to the exact business name on your proposal, and valid in your jurisdiction. Denver and nearby municipalities can have very different local requirements, so do not assume one city's license carries everywhere.
State-specific tips
- › If your property is in the Denver area, verify both the municipality and the specific suburb; local licensing does not automatically travel.
- › For roofing after hail season, ask which local jurisdictions the contractor is currently licensed to work in.
- › Check trade licenses separately for electrical and plumbing even if the main remodel contract comes from a general contractor.
- › If the contractor says Colorado has no license requirement, treat that as incomplete and ask about your city or county.
- › Mountain-town permit rules can be stricter than statewide assumptions, especially for structural, septic, and wildfire-related work.

Frequently Asked Questions
- Does Colorado require general contractors to be licensed statewide?
- No. Colorado has no statewide general contractor license. Licensing and registration requirements are set by individual cities and counties, so what is required in Denver differs from what is required in Colorado Springs or an unincorporated county. The Colorado Attorney General's consumer protection office (C.R.S. §6-1-101 et seq.) provides the primary statewide protection for homeowners dealing with contractor fraud or deceptive practices.
- How do I verify a contractor is legitimate in Colorado without a state license to check?
- Confirm the contractor is registered as a business with the Colorado Secretary of State at sos.colorado.gov. Ask whether they have pulled permits on similar local projects — a contractor unwilling to pull permits is a red flag. Request current certificates of general liability insurance and workers' compensation, then verify both directly with the insurers. Check the Better Business Bureau (bbb.org) and ask for references from recent Colorado projects.
- Are specialty trade contractors licensed in Colorado?
- Yes. Electrical contractors must be licensed through the Colorado Department of Regulatory Agencies (DORA) under C.R.S. §12-115. Master and journeyman electricians are separately licensed. Plumbing contractors are licensed through the Colorado Department of Regulatory Agencies as well. HVAC and mechanical contractors are not licensed at the state level in Colorado — verify those through local jurisdictions. Specialty trade licenses can be verified at dora.colorado.gov.
- Does my city or county require contractors to be licensed in Colorado?
- Many do. Denver requires a contractor license through Denver Community Planning and Development (denvergov.org/cpd). Colorado Springs requires contractor registration through its Pikes Peak Regional Building Department. Aurora and Boulder both have local contractor licensing programs. Always contact your local building department before hiring — a licensed contractor in one Colorado jurisdiction is not automatically licensed in another.
- What insurance should I require from a contractor in Colorado?
- Require at minimum general liability insurance (at least $500,000 per occurrence is a common benchmark for residential work) and workers' compensation insurance. Colorado requires workers' comp for employers with one or more employees under C.R.S. §8-40-202. Without a state contractor board to verify coverage, you bear more of the verification burden — always request certificates of insurance and call the insurer to confirm the policies are active and in force.
- Is a written contract required for home improvement work in Colorado?
- Colorado has no specific home improvement contract statute setting a dollar threshold or required contract elements. However, the Colorado Consumer Protection Act (C.R.S. §6-1-105) prohibits deceptive trade practices and applies to contractor relationships. As a practical matter, always get a written contract for any project — it should include the full scope of work, materials, payment schedule, start and completion dates, and a lien waiver provision. A written contract is your primary legal protection in a state without a licensing board.
- What recourse do I have if a contractor does poor work or abandons my project in Colorado?
- File a complaint with the Colorado Attorney General's Office under the Colorado Consumer Protection Act (C.R.S. §6-1-113) — the AG can pursue civil penalties and injunctions against deceptive contractors. You may also sue in small claims court (up to $7,500) or district court for larger amounts. If the contractor committed fraud, contact local law enforcement. Document everything in writing and keep all contracts, receipts, photos, and communications.
- Where do I find contractor requirements for my city or county in Colorado?
- Start with your local building department — Colorado's building departments vary widely by jurisdiction. Denver's requirements are at denvergov.org/cpd; Colorado Springs uses the Pikes Peak Regional Building Department (ppbuild.com); Aurora's building division is at auroragov.org; Boulder's is at bouldercolorado.gov/building-safety. For unincorporated areas, contact your county's planning and building department. Colorado has no central directory of local contractor requirements.
- How do mechanic's liens work in Colorado and how can I protect myself?
- Under C.R.S. §38-22-101 et seq., a contractor, subcontractor, or material supplier who is not paid can file a mechanic's lien against your property — even if you paid the general contractor in full. In Colorado, a lien must be filed within four months of the last work or materials furnished. Protect yourself by requiring the GC to provide lien waivers from all major subcontractors and suppliers at each payment milestone, and consider using a title company to manage disbursements on larger projects.
