The mistakes that most often get contractor license applications returned, voided or denied, and how to avoid each one.

Checked against CSLB sources 3 minute read Help in English & Español

Quick answer

Most returned applications come down to missing information: unsigned or undated forms, forms filled out in pencil, experience that is too vague or certified by someone without firsthand knowledge, a missing fee or transcripts, or applying for more than one classification with an exam application. Missed 90 day deadlines can void the application entirely.

Form and Signature Mistakes

  • Filling out forms in pencil (they are returned)
  • Missing dates or missing signatures from anyone listed on the application
  • Applying for more than one classification on an exam application
  • Leaving out the $450 fee or sending bonds and the license fee too early

Experience Mistakes

  • Describing experience in vague terms instead of specific tasks
  • Experience that does not match the classification
  • Counting helper, laborer or apprentice time as journey level experience
  • A certifier who did not personally observe the work
  • Owner builder experience without a Project List form for each project
  • Claiming education credit without official sealed transcripts

Missed Deadlines

  • Not resubmitting a returned application within 90 days (it becomes void)
  • Not sending CSLB the Live Scan form copy within 90 days (it can void the application)
  • Not passing the exams within 18 months of acceptance (it becomes void)

Fingerprinting Problems

  • The name entered at Live Scan does not match the name on file with CSLB
  • A Social Security number entered incorrectly
  • Poor quality prints that are rejected and must be redone

Common CSLB Application Mistakes and Rejections: FAQs

Will I lose my fee if my application is returned?

The fee stays with your application if you resubmit within 90 days. If the application becomes void, you must reapply with a new fee.

Can I add experience after CSLB accepts my application?

No. Additional experience verification is not accepted after acceptance, so include everything up front.

What is the difference between returned and denied?

A returned application needs corrections and can be resubmitted within 90 days. A denial is a formal decision not to issue the license, for example after an investigation.
