Are plumbers required to be licensed in Colorado?
Yes, you’re required to have a plumbing license to perform work in Colorado. Licenses vary based on years of experience and what levels you’re allowed to supervise. With your license, you’ll be able to work on plumbing projects such as pipe installation, plumbing repairs, and sewage repairs.
The type of projects you’re allowed to work on will depend on the type of license you have: residential plumbers can perform plumbing work on residential projects, whereas Journeyman plumbers can work on both residential and commercial projects.
Those looking to perform plumbing work on their own home aren’t required to get a plumbing license but will still need to obtain the necessary permits. If you’re interested in starting your own plumbing business, you’ll need to look into getting a contractor’s license from your local jurisdiction. Licenses are issued by Colorado’s Department of Regulatory Agencies (DORA) Division of Professions and Occupations.
Types of plumbing licenses in Colorado
Colorado offers a few types of plumbing licenses that vary based on your level of experience. To get started earning your license, you’ll start off as an apprentice. As you get more experience, you can apply for higher-level licenses until you reach your master plumbing license:
- Apprentice: less than 2 years of experience
- Residential: 2 years of experience
- Journeyman: 4 years of experience
- Master: 5 years of full-time experience
Plumbers who want to own their own business will also need to get a contractor’s license from their local jurisdiction. In Denver, the Contractor’s License will be issued to individuals who have a state-issued Master Plumber license or have an individual who holds a city-issued supervisor certificate to qualify the license.
Colorado plumbing license requirements
There are a few requirements you’ll need to start the process of becoming a master plumber. The requirements needed to receive your license are as follows:

Colorado does not have any reciprocity agreements with other states for plumbing licenses but out-of-state license holders can apply for a Colorado license via endorsement.
To obtain your license via endorsement, you must provide proof of the required work experience and upload a copy of your license.

If your license has expired, you must stop all plumbing work and pay the late fee to renew your license. You’ll have a 60-day grace period from the expiration date to renew your license. Failure to renew within the grace period will result in a delinquent license and you’ll need to complete a reinstatement process. You can check if your license has expired using the DORA online portal.
Requirements for business owners
To start a plumbing business, you’ll need to complete a few additional steps beyond receiving your license. Only those with a locally-issued contractor’s license will be able to operate a plumbing business.
When starting a business, you’ll first need to establish the structure in which you’ll operate. You can choose from business structures such as an LLC, sole proprietorship, or partnership. Once you decide on your business structure, you’ll need to choose a name and register your business with your local government.
You’ll need to meet the following requirements to start your business:
- Get the necessary insurance: Business owners are required to obtain general liability, worker’s compensation, and commercial automobile insurance. The minimum coverage amount required depends on the monetary limit of your contractor’s license. This monetary amount is based on your financial statement.
- Obtain the necessary permits: The specific permits you need will depend on the local jurisdiction of the location where the project will take place. Check with your local Building and Codes office for what specific permits you’ll need.
On average, it costs around $10,000 to get all the tools, equipment, and insurance needed to start a plumbing business. If needed, you can apply for a small business loan to help cover the initial costs. You can also check with your local government to see if any small business grants are available.
