Colorado Contractor License


Thinking about launching a construction business in Colorado? Your first step is to obtain a Colorado contractor license, which gives you the right to operate. 

There are no statewide requirements for the licensing of general contractors. You have to obtain a Colorado general contractor license from your municipal authorities, such as in Denver and Boulder. Electricians and plumbers, on the other hand, have to get a state license from the Department of Regulatory Agencies. 

In the guide below, you can find out the essentials about the licensing process for all types of contractors across the state, and specific requirements about getting a Denver contractor license. 

The Colorado Contractor License Requirements

For all types of licenses, you have to undergo a business licensing procedure in order to set up your operations in the state. 

Business Entity Registration 

You have to register your business with the Colorado Secretary of State. You can select between a few different structures, which are sole proprietorship, general partnership, corporation and LCC. 

Trade Name 

In case you will be doing business under a trade name, you have to obtain it from the Secretary of State as well. 

Tax ID

You have to obtain a Taxpayer Identification Number and Certification from the Colorado Department of Revenue.

Complete the Colorado Contractor License Application

  • Construction (General Contractor Class A, Building Contractor Class B and Residential Contractor Class C)
  • Demolition / Moving
  • Electrical (includes Access Control and Electrical Signal)
  • Fire Protection
  • Mechanical
  • Specialty Class D

The licensing authority in the city is the Community Planning and Development Department.

You first need to apply for a supervisor certificate, or alternatively, you should already hold a Colorado electrical license from the Department of Regulatory Agencies. In order to obtain a supervisor certificate in Denver, you have to provide proof of the following:

  • Appropriate and sufficient education and experience
  • Previous licenses and certificates
  • Affidavit of Lawful Presence
  • Successful completion of a test

Once you have obtained a supervisor certificate or state-level electrical license, you can apply for a contractor license via the application form online. The Department will review your application within 10 days after you have submitted it. 

License and Registration Fees

The licensing fee for the Denver contractor license is $250 for three years. The supervisor certificate fee is $60

Provide a Surety Bond and Insurance

Depending on the Colorado contractor license that you want to obtain, you may have to get a surety bond and insurance in addition to meeting the requirements listed above. 

Worker’s compensation insurance

If you will be hiring employees, you will need to get worker’s compensation insurance. You can find information about it from the Department of Labor and Employment.

Surety Bond 

For some types of contractor licenses in Colorado, you have to obtain a surety bond. This is a protection mechanism that safeguards the interests of your customers. 

The amounts of the required Colorado contractor license bond vary, as they are set by the city licensing authorities. Here are some of the bond amounts in the state:

  • Denver cement sidewalk contractor bond - $10,000
  • Denver structural contractor bond - $25,000
  • Denver sewer contractor and general contractor bond - $50,000

In order to get bonded, you have to pay a small fraction of the amount. It is called the bond premium. If your finances are in good shape, you can expect rates between 0.75% and 5%
