How to Get a Colorado Contractor License
If you want to work as a contractor in Colorado, you need to understand its specific regulations.
Unlike the majority of states in the U.S., Colorado does not require general contractor licensing at the state level. This only applies to plumbing and electrical contractors, who must carry state-issued licenses.
However, most general contractor projects are regulated at the local level. So, you may have to get a license or permit in the counties and cities where you work.
Whether you're seeking state registration or dealing with your local city licensing office, we are here to guide you through the essential details. Count on us to equip you with the information you need to obtain and navigate your contractor's license in Colorado successfully.
Types of Contractor License in Colorado
In the State of Colorado, electricians and plumbers require state-level licenses, which are handled by the Colorado Department of Regulatory Agencies (DORA). General contractor Licenses are handled at the municipal level.
Here are the main license types available:
Electrical License
The electrical contractor license has three levels—residential wireman, journeyman, and master electrician.
Note: Electrical contractors may be eligible for reciprocity if they hold a journeyman or master electrician’s license from a state that’s in good standing with National Electrical Reciprocal Alliance (NERA), or from another entity or jurisdiction that has a reciprocity agreement with the board. Reciprocity will only be granted at the journeyman level regardless of previous level attained. Full prerequisites can be found under the rules and regulations section of the Electrical Board’s Laws, Rules and Policies.
Plumbing License
There are multiple classifications available for plumbing licensing in Colorado, including residential, journeyman, and master plumber. Licensed plumbers can register as a plumbing contractor once they reach the level of master plumber or have an employee with that title.
Check out all the Laws, Rules and Policies at the State Plumbing Board section.
General Contractors
General contractors and subcontractors—building contractors, mechanical contractors, contractors for roofing and fire protection—are licensed at the municipal level and are subject to regulations passed by individual cities.
For this reason, it is essential to review the appropriate legislation based on your type of work. Various municipalities may also have additional registration requirements for plumbers and electricians.
Note: Some cities may also require a business license. If this is the case, applicants will first need to register their business with the Secretary of State. To do so, you may need proof of tax registration (identification number, sales and use tax, income tax withholding), general liability insurance, and other requirements to proceed.

4. Pass Examination
Once your application has been approved by the Colorado State Board, you’ll receive a letter of acceptance and information on where to obtain a testing handbook. This also provides testing locations, fees, and schedules. Tests are administered by a private agency, PSI.
Review the licensure by examination section on the Electrical Board and State Plumbing Board sites to see which codes you will be tested on.
5. Obtain Your Contractor License Bond
Contractor licenses are awarded at the municipal level, and other requirements such as a contractor license bond can be made at this level.
We are frequently questioned about the necessity of a Colorado Contractor License Bond. Beyond compliance, the bond serves as a powerful assurance to your clients and the municipality. It is required to ensure you will complete any contracted work and carry out that work in accordance with international building codes and any other local regulations.
A contractor license bond costs a small percent of the required bond total—usually 1% - 10%, pending good credit and that the underwriting process deems you low risk. For example, a $20,000 bond will cost a flat fee of approximately $200 - $2000.
Applying for Colorado Contracting Licenses by City
