Applying for a supervisor certificate is the first step to obtaining a contractor license. Each certificate type must be applied for separately.
Holders of a state electrical or plumbing license can apply directly for a contractor license and do not need a supervisor certificate first. For all other work, license applications will not be accepted until supervisor certificates have been approved.
Use the links below to review what work is allowed under each certificate type, the minimum experience required in order to apply for the certificate, and whether passing an ICC exam is required. Specialty Class D certificates do not require an exam.
The online certificate application will require you to upload notarized letters of experience that document how you meet the minimum experience needed for that certificate type. These letters must come from owners or officers of current or previous employers, or clients that have hired you to do work. If you are the owner of the company, you must go to previous employers or clients that you have done work for as you can not be your own reference.
Notarized letters should be in the following format:
Colorado Revised Statutes require that applicants submit an Affidavit of Lawful Presence and Secure and Verifiable Identification as proof that they are lawfully present in the United States.
Complete the Affidavit of Lawful Presence (PDF) and upload it with your certificate application.
Once your application is submitted online, it will take approximately 7 to 10 business days to be reviewed. You will receive an approval or denial email once the application has been reviewed, and will then be able to return to the online application to pay for the certificate.
Mail-in applications can take up to 14 business days to be processed. Do not submit payment with your application. You will be notified by telephone of application approval or rejection. (Please note that the Contractor License office can only give application status to the actual applicant.)
In the event that your application is not approved, you will be given the opportunity to apply a second time. Additional documentation is required.
However, if the application is not approved the second time, there is a six-month waiting period before applicants can re-apply for the same certificate type.
If your application is approved, you will have 90 days to procure your certificate by paying the appropriate fee amount. Specialty D certificates are valid for 3 years.
If your application is approved, you will have 90 days to procure your certificate by submitting the official ICC pass letter and your payment.
Approved supervisor certificate holders may now apply online for a contractor's license.
