Colorado Residential Rent Increase Notice

Colorado Residential Rent Increase Notice

Use this form only after completing the legal, lease, coverage, and applicable rent-restriction checks below. Colorado bars county and municipal rent-control ordinances on private residential housing, while allowing specified voluntary affordable-housing agreements and deed restrictions. Check whether either applies to this property. Colo. Rev. Stat. § 38-12-301.
