Colorado Regulatory Research

Teaches how to locate Colorado regulations, including historical regulations.


Since 2007, the official source for Colorado regulations is the online version available through the Colorado Secretary of State's website.  This guide provides instructions on how to search for regulations using this version.  

Researchers can still locate regulations using an unofficial source from LexisNexis.  Sometimes researchers will need to use the print resources if researching superseded regulations.

Finally, Westlaw, Lexis Advance and Bloomberg Law each provide Colorado regulations on their research platforms.  Subscribers of those services should consult those systems for details on how to research them.
