Reciprocity

If you have a valid contractor license in, Arizona, Nevada or Utah, you may be eligible for a California contractor license without taking the trade portion of the exam.

The CSLB believes that reciprocity among respective licensing programs is a valuable benefit. Therefor specified classifications where practice and licensing requirements are either identical or fundamentally indistinguishable from California qualify for reciprocity. Reciprocity, if you are eligible, can make it much easier to get a license.

REMEMBER – CSLB may waive the Trade portion of the exam, but retains the right to require the Trade exam.

IMPORTANT – When the applicant is granted reciprocity, they are still be required to take the Law and Business portion of CSLB’s Contractor exam.

Reciprocity Exam Requirements:

Reciprocity requirements are the same in each participating state:

  1. The contractor must be applying for a license in a classification that appears on that state’s Reciprocal Classifications List.
  2. Also, they must have held an active license in good standing in one of the reciprocal states for the previous five years.
  3. Submit to CSLB the Request for Verification of License form that is completed by the licensing entity under which he or she already is licensed.
  4. Finally, complete the Application for Original Contractor’s License.

For example, a C-7 Carpentry license in Arizona corresponds to a C-5 Framing and Rough Carpentry license in California.

The following are the Reciprocal License Classifications for CALIFORNIA, ARIZONA, NEVADA, and UTAH.
