By January 1, 2027, developers and deployers of automated decision-making technology must notify Colorado residents when ADMT materially influences consequential decisions, explain adverse outcomes, enable meaningful human review, and maintain developer documentation.
What it requires
You must give consumers clear notice when automated decision-making technology (ADMT) will materially influence a consequential decision affecting them. For adverse outcomes, you must provide explanation. You must offer meaningful human review of the automated decision. You must keep developer documentation on file. The law replaces Colorado's earlier AI Act and applies to ADMT that materially influences consequential decisions about Colorado residents.
Who it binds
Developers who build ADMT systems and deployers who use them to make consequential decisions affecting Colorado residents. This spans product teams, engineering leads, privacy and compliance leads, and business units that rely on algorithmic decision-making in areas like credit, housing, employment, benefits, and other high-impact contexts.
How to check whether you comply
Audit your decision-making systems to identify which ones use automation and which decisions qualify as 'consequential' under Colorado law.
Verify your consumer notice templates include the required disclosure that ADMT is being used and what decision it influences.
Document your human review workflow and confirm it allows meaningful intervention or override of automated recommendations.
Maintain and version developer documentation covering your ADMT system design, data, logic, and outcomes.
What teams get wrong
This deadline's enforcement status is uncertain. A federal lawsuit reportedly has enforcement on hold; verify the current litigation status and any agency guidance before treating this as fully active. The confidence level on this record is uncertain, so confirm with the Colorado Attorney General's office or check for agency rulemaking before final implementation.
Status: uncertain. Verify against the primary source before relying on this date.
