Colorado AI Regulations
Colorado's first AI Act (SB 24-205) never took effect: SB 26-189 repealed and replaced it in May 2026 with a narrower automated-decision-making law whose duties start January 1, 2027.
Colorado passed the first comprehensive state AI statute in the US, then rewrote it before it applied. SB 26-189, signed May 14, 2026, repeals and reenacts SB 24-205 as a law governing automated decision-making technology used in consequential decisions about employment, lending, housing, health care, insurance, education, and essential government services.
The new law replaces the duty-of-care and impact-assessment framework with developer documentation, consumer notice, post-decision explanations, human-review rights, and record-keeping. Duties begin January 1, 2027.
