Colorado Automated Decision-Making Technology Act (SB26-189)

Replaces the 2024 Colorado AI Act. Covers automated decision-making technology that materially influences decisions on education, jobs, housing, lending, insurance, health care and government services. Developers document systems for deployers; deployers give notice, explain adverse outcomes within 30 days, and offer correction and human review. AG enforces; no new private right of action.

What this means for you

If you build AI

  • From Jan 1, 2027, give deployers documentation: intended uses, training data categories, known limits and human-review instructions.
  • Tell deployers about material updates, and keep compliance records for at least 3 years.

If you deploy AI

  • Give clear notice when a covered ADMT is used, and a plain-language explanation within 30 days after an adverse decision.
  • Set up processes for data correction requests and meaningful human review and reconsideration.

If you use AI

  • From 2027 you should be told when an automated tool helps decide a job, loan, housing, insurance or similar outcome.
  • After an adverse decision you can ask for your data, corrections and a human review. You cannot sue under this act itself.
