Contractor Licensing

Contractor Licenses issued by the City of Aspen Building Department are valid jointly in Aspen and Pitkin County. These are issued separately from your Business License, both of which are required. Prior to applying for or renewing your Contractor License you must first have a valid BEST Card or other valid certification.

Types of Licenses

The type of contractor licenses or registrations you need depend on your roles and responsibilities on a project. These licenses are valid in both Aspen and Pitkin County. Contractor license descriptions can be found here.
