Colorado Employment Screening Laws in 2025: What Employers Need to Know

 

Employment screening laws in Colorado have evolved in recent years, with new state and local regulations aimed at promoting fair hiring practices, protecting applicant privacy, and reducing barriers to employment.

As of 2025, employers in Colorado must comply with several key laws governing background checks, credit history inquiries, and criminal record screening.

Additionally, some municipalities have enacted stricter rules. Below is a comprehensive overview of the current legal landscape. Don’t forget to begin by first adhering to federal FCRA laws.

  • Employers may conduct background checks only after a conditional job offer.
  • Individualized assessment required if denying employment based on criminal history, considering factors such as the nature of the offense, time passed, and relevance to the job.

Follow a two-step adverse action process if denying employment based on background check results:

  • Pre-adverse action notice (with copy of report and rights summary).
  • Final adverse action notice (after waiting period, if no dispute is made).
Allow at least 5 business days (state) or 10 business days (Denver) for applicant response before final denial.

Drug Testing & Marijuana Policies

Do not discriminate against legal off-duty marijuana use unless job is safety-sensitive.
