What is a B.E.S.T. Card?
B.E.S.T. stands for Board of Examiners for Standardized Testing. B.E.S.T. is a program used by Aspen/Pitkin County and many other jurisdictions in the Roaring Fork Valley and along the I-70 corridor to verify the level of Code knowledge for contractors and job supervisors.
A B.E.S.T. Card is not the same as a Contractor’s License.
Please contact the Pitkin County Community Development Department for questions regarding B.E.S.T. testing or to schedule a test at (970) 920-5526.
Visit the Pitkin County Community Development website for additional information.

Colorado state law allows homeowners to build, remodel and otherwise work on their own homes and to install and work on plumbing and electrical systems. The City of Aspen and Pitkin County require homeowner/builders to take a 25-question test on the 2009 International Residential Code to demonstrate that they are aware of the minimum code standards they must comply with. There is no passing grade and no fee to take the test. Tests are taken in the Pitkin County Community Development Department offices.
Homeowner/builders must also sign an Insurance Affidavit to acknowledge the responsibility for maintaining minimum levels of employee liability and public liability insurance. No permit can be issued to an owner who has not taken the test and signed the affidavit.
A homeowner/builder is an individual personally engaged in the construction of a single-family residence or accessory building for his or her own use. The following conditions apply:
The owner/builder cannot be issued more than one building permit for new home construction in any two-year period; this restriction does not apply to work done on the same building, i.e. an owner may be issued more than one permit to remodel his/her home within a two-year period, but may not construct two residences within that period.
The owner/builder is responsible for ensuring that all paid personnel are covered by workman’s compensation as required by state law.
The owner/builder must be present at the work site during all inspections unless prior arrangements have been made with the building department.
The owner/builder is required to sign an ‘Owner/Builder Affidavit’.
For the purposes of this program, only buildings that fall under the International Residential Code are considered single-family residences. That means detached single-family residences, duplexes and IRC townhouses. The owners of a condominium unit are not included since the results of their construction efforts directly impact the safety of adjoining units.
Please call (970) 920-5526 for more information and to schedule a test.
