Colorado contractor license requirements
Colorado does not issue one broad statewide general-contractor license. The state licenses regulated trades such as plumbing and electrical, while cities and counties commonly control general-contractor licensing, registration, supervision, and local exams. Start with the Colorado Division of Professions and Occupations (DPO). Confirm the exact credential for your trade, project size, and location before bidding.

How to start a contracting business in Colorado
Use this order as a planning path. Open each official state link and confirm what applies to your entity, trade, project size, and job location.
Choose the business structure
Compare the entity options available in Colorado before you file. Your structure affects registration, taxes, ownership records, and the documents a licensing agency may request.

Register the business
Use the official Colorado filing system to form or register the entity and confirm whether a separate business name filing is needed.
Set up state tax accounts
Check the state revenue agency for business tax registration, sales or marketplace tax rules, withholding, and any industry-specific accounts that apply to your work.
Confirm the contractor credential
Start with Colorado Division of Professions and Occupations. Match the license, registration, classification, or local requirement to the exact trade and scope you plan to sell.

Check permits and local rules
State registration does not replace city, county, building-department, or trade-permit rules. Confirm the job address and scope before bidding or starting work.
Register before hiring
If you will have employees, confirm employer registration, withholding, unemployment, workers compensation, and workplace-safety responsibilities with the responsible agencies.

What to verify before you bid
- Match the credential to the work. General building, residential work, electrical, plumbing, HVAC, roofing, public work, and specialty trades can follow different rules.
- Check the project location. A state registration never replaces city or county contractor registration, permits, bond requirements, or local business licensing.
- Set up the business first when required. Confirm the entity name, tax account, workers' compensation status, and insurance certificate match the name used on the license application and contracts.
- Confirm money and deadlines directly. Fees, financial limits, bonds, insurance minimums, renewal dates, notice rules, and lien deadlines are deliberately omitted unless they were checked against the responsible agency or statute.
