City of Grand Junction Contractor's License

Licensing is only required in the city limits of Grand Junction. The Mesa County Building Department administers the licensing program for the City of Grand Junction.

NOTICE: The Mesa County Building Department will only accept the 2012 and 2015 Code Cycle testing for contractor licensing through December 31, 2021. Effective January 1, 2022, any new license applications will require proof of Code Cycle 2018 or newer testing.



Often, contractors who build in several areas must pass an exam in each jurisdiction. With the successful passage of an ICC Contractor Exam, contractors can be secure in the knowledge that their results will be honored by the many agencies that participate in the program. Building departments will benefit from such commonality as well, having a solid foundation upon which to issue licenses to practice.

The examination measures the level of knowledge of building codes and establishes a basis for the issuance of licenses to practice–and results in a test that is acceptable from one jurisdiction to another.

Finally, contractors, building departments and their customers can benefit from the standardization of criteria determining contractor proficiency.


Notice of Contemporaneous Reviews for Electrical and Plumbing Licenses

This notice is the result of HB19-1086 (Plumbing) and 5B19-156 (Electrical).  HB19-1086 becomes effective January 1, 2020. 5B19-156 becomes effective July 1, 2019.

Procedure for Contemporaneous Reviews of Electrical and Plumbing License and Apprenticeship Requirements 

This standard procedure has been developed for conducting contemporaneous reviews to ensure consistent, timely and efficient enforcement of Colorado's electrical and plumbing licensure and apprenticeship requirements.  Inspections of projects requiring an electrical or plumbing permit must include a contemporaneous review of electrical and plumbing licenses, when possible.

Contemporaneous reviews may include a full or partial review of the electricians, plumbers and apprentices working at a job site being inspected, at the discretion of the inspector, based on the inspector's familiarity with the installers or other relevant factors.
Inspectors may perform contemporaneous reviews at any time. Inspectors may conduct occasional, random, on-site inspections while actual plumbing or electrical work is being conducted, with a focus on large commercial and multi-family residential projects.

If a contemporaneous review reveals any non-compliance with Colorado's electrical and plumbing licensure or apprenticeship requirements, the inspector who performed the review shall promptly notify his or her immediate supervisor. Inspectors may file a complaint with the State electrical and plumbing boards for any violation of C.R.S. Title 12, Article 23 (Electricians) or C.R.S. Title 12, Article 58 (Plumbers).
