Reinstatement of Contractor Licenses and Certificates

License Reinstatements

If the license has been expired for more than one year, the license holder must complete a new license application and submit supporting documents as required for a new license. Once reinstated, the contractor's license number will remain the same.

Certificate Reinstatements

  • Supervisor certificates: Standards and requirements
    • Within one year of expiration, the certificate may be reissued without a new application.
    • If the certificate holder reapplies within 3 years of the date of expiration, a new certificate application is required, but not a new exam.
    • If the certificate holder reapplies more than 3 years after expiration, a new certificate application, new notarized letters of experience, and a new exam will be required (if an exam is required for that certificate type).

Expiration Dates 

Expiration dates are listed on each certificate/license and on the city's licensed contractor search page
