Who this covers — and who it does not

This page covers rent increases in Colorado for a residential tenancy — whether there is a cap, and what notice a landlord must give.

It does not cover commercial leases, subsidised housing (which follows federal rules), or any city whose local ordinance differs from the state rule.

Is there a rent cap?

Sources and how to verify them

Every figure on this page comes from the official text or a state court opinion, not from a summary. The table below lists each provision used and the date it was last checked.

Where the official text and a secondary summary disagree, this page follows the official text and says so. Where a provision admits of more than one reading, that is flagged rather than smoothed over.

When you need a lawyer instead of a tool

A self-help guide is the right starting point for understanding your position. Get legal help if:

• You have received an eviction notice — the timeline is now court-driven
• The dispute involves discrimination, unsafe conditions or retaliation
• Your landlord has filed anything in court already
• You are unsure whether a local ordinance changes the state rule

Local legal aid organisations and tenant unions offer free help for qualifying cases. They are independent of this site — we list them because they are the right place to go, not because they link here.
