SB 26-189, signed by Governor Polis on May 14, 2026 and effective January 1, 2027, repeals and re-enacts SB 24-205. It removes the 2024 duty of care, risk management program and impact assessment requirements and replaces them with a point-of-interaction notice, a post-adverse-outcome disclosure, and limited consumer rights for people affected by covered automated decision-making technology (ADMT) used in consequential decisions such as employment, education, housing and financial services. Enforcement is also on hold in xAI's lawsuit against the attorney general (X.AI LLC v. Weiser, D. Colo. No. 1:26-cv-01515): on April 27, 2026 the court granted the parties' stipulation and ordered that the attorney general not start enforcement under SB 24-205, or legislation replacing it enacted that session, until 14 days after the court rules on xAI's preliminary injunction motion. xAI files that motion within 28 days after final rules are adopted.
If you deploy ADMT that materially influences a consequential decision about a Colorado resident, plan for four things by January 1, 2027: a clear and conspicuous notice at the point of interaction, a plain-language description of the tool's role within 30 days after an adverse outcome, handling requests after an adverse outcome to get and correct the personal data used and to ask for meaningful human review and reconsideration (to the extent commercially reasonable), and keeping compliance records for at least 3 years. Developers must give deployers technical documentation (intended uses, categories of training data, known limitations, instructions for use and human review) and tell them about material updates. The attorney general enforces the act and must adopt rules on the adverse-outcome disclosure by January 1, 2027. We checked these points against the signed act (C.R.S. 6-1-1702 to 6-1-1706). The rules are not final yet: the attorney general's office filed proposed rules on August 11, 2026, posted an interim redline draft on October 6, 2026, and takes written comments through October 26, 2026, the day of its rulemaking hearing in Denver. Read the interim draft before you lock your notice wording.
