Contractor Licensing

The type of contractor licenses or registrations you need depend on your roles and responsibilities on a project. Contractor Licenses issued by the City of Aspen Building Department are valid in both in the City of Aspen and Pitkin County. These are issued separately from your Business License, both of which are required.
