When will my CSL expire?

The expiration date is listed on your official CSL card. You can also view it online by logging into your MyLicenseOne account on the DOL website. Be sure to check this date so you can complete your CE and submit your renewal before it expires.

What if my license has already expired?

The DOL offers a one-year grace period with no additional steps or fees required to renew. After one year, an extra $100 fee is added. If your license has expired for more than two years, you must apply for a new license and pass the exam again.

How does the renewal process work?

To ensure a smooth renewal, the Division of Occupational Licensing (DOL) recommends completing the education requirements 60 days before your license expires. You will also need to submit proof that you attended relevant courses.

When you complete your construction supervisor training with Builders License Training Institute, we provide a downloadable completion certificate and submit your hours to the state every Wednesday. This ensures your CE is documented properly for your renewal.

You can then apply in one of three ways:

  1. Online using the MyLicenseOne Portal
  2. By mail (requires asking for an application)
  3. In person at the Office of Public Safety and Inspections building
