Is there a cap on rent increases in Colorado?
No Colorado law caps the amount of a residential rent increase.
Local rent control
- None. Counties and municipalities may not enact residential rent control (C.R.S. § 38-12-301). A 2023 repeal bill (HB23-1115) failed; no later repeal was found.
How much notice is required?
For a tenancy without a written agreement, at least 60 days' written notice of a rent increase (C.R.S. § 38-12-701). A landlord may not serve a notice to quit mainly to raise the rent and avoid this rule. With a written lease, the notice is set by the lease.
How often can rent go up?
At most one increase in any 12-month period, regardless of the type of lease (C.R.S. § 38-12-702).
During a fixed-term lease
Only if the lease allows it, and still at most once in 12 months (C.R.S. § 38-12-702).
Retaliatory increases
Retaliation for good-faith habitability complaints, tenant organizing or exercising legal rights is prohibited, including by raising the rent (C.R.S. § 38-12-509).
Other rules to know
- Pet rent is capped at the greater of $35 a month or 1.5% of the monthly rent, and pet deposits at $300 (HB23-1068, since January 1, 2024).
- Mobile home parks: increases are barred while a park is unregistered or out of compliance with a final state order (HB24-1294).
