Do you need a state license in Colorado?
Colorado does not issue a statewide general contractor license. Any license you need comes from the city or county where the job is, so the rules can change from one town to the next.
Licensing is local. Denver requires a supervisor certificate, or an employee who holds one, before issuing a contractor license, and renewals run every one to three years. Denver does not accept other counties or states licenses. Estes Park requires general contractors to hold a Town contractor license. In unincorporated Jefferson County, a building contractor must hold a license from the county Division of Building Safety before doing business.
How to get set up in Colorado, step by step
- List the cities and counties where you will work.
- Check each building department for its general contractor license rules.
- In Denver, get a supervisor certificate (or hire someone who holds one) first, then the contractor license.
- In unincorporated Jefferson County, get a building contractor license from the county Division of Building Safety.
- Pull local permits for each job.
What it costs in Colorado
There is no state license fee for general contractor work in Colorado. Ask the city or county where you work about any local fees.
Good to know in Colorado
- Plumbers and electricians must be licensed or registered with the State of Colorado.
- A 2026 bill to create an optional state certification for residential construction contractors (HB 26-1415) was lost, so there is still no state credential.
Once you are cleared to work
The license lets you take the work. Getting the work is the next job.
- Register the business. If you work under a name other than your own, register it where your state asks (often the Secretary of State, sometimes the county), and keep the name the same on your license, your truck and your invoices.
- Claim your Google Business Profile. It is the listing people see when they search for a contractor near them. Fill in your service area, hours and real photos of your work.
- Put up a website that shows the license. Customers look for it before they call. Koira builds a contractor website for you and keeps it current.
- See where you stand. The free Koira report checks how your business shows up in search and on maps against shops near you.
