Colo. Rev. Stat. § 29-1-1201
The general assembly hereby finds, determines, and declares that the imposition of restrictions by a local government upon when or how often individuals may meet upon private residential property to pray, worship, or otherwise study or discuss issues relating to religious beliefs infringes upon the fundamental right to the free exercise of religion. The general assembly further finds and declares that such restrictions are of significant interest to people living outside the jurisdiction of the local government. In addition, the ability of individuals to freely determine when and how often they wish to meet for such purposes should be uniform throughout the state. Accordingly, the general assembly finds that restrictions that specifically limit when or how often individuals may meet upon private residential property to pray, worship, or otherwise study or discuss issues relating to religious beliefs are a matter of statewide concern and the provisions of this section shall preempt any provisions of any local government ordinance, resolution, regulation, or other restriction to the contrary.
