Colorado Rent Increase Notice

Quick answer: raising the rent in Colorado takes 60 days' advance written notice (Colo. Rev. Stat. 38-12-701), and the increase is limited: no dollar limit, but rent may not be increased more than once in any 12-month period (Colo. Rev. Stat. 38-12-702). On a fixed-term lease, the rent is locked until renewal unless the lease says otherwise. Details below.

A rent increase notice tells the tenant, in writing and in advance, that the rent changes on a named date. On a fixed-term lease the rent is locked until renewal unless the lease says otherwise; on a month-to-month tenancy the increase is a change of terms with its own notice clock. Colorado requires 60 days' advance written notice (Colo. Rev. Stat. 38-12-701).

Verify before you rely on it

Rent increase statutes and local rent control ordinances are moving targets: several states have added caps or longer notice periods in recent years, and cities can regulate increases where the state does not. Confirm the current Colorado rule in the statute cited above (or with your local rent board or court self-help resources) before serving the notice, and follow the lease when it requires more.

Colorado rent increase notice requirements

Legally, raising the rent in Colorado is a modification of the rental contract, and a landlord cannot modify a contract unilaterally except where the tenancy itself allows it: at renewal of a fixed-term lease, or with proper advance notice on a month-to-month arrangement. The rent increase notice is the document that exercises that right, in writing, with a clean effective date.

Colorado sets the timing by statute: 60 days' advance written notice under Colo. Rev. Stat. 38-12-701. Count from the day the notice is delivered, not the day it is written, and land the effective date on the start of a rental period unless the lease says otherwise.

Colorado also regulates the size of the increase: no dollar limit, but rent may not be increased more than once in any 12-month period (Colo. Rev. Stat. 38-12-702). Check the current numbers before writing the new rent into the notice; a figure over the limit is not trimmed to the maximum, it exposes the whole increase to challenge.

The lease term is the other clock. A fixed-term lease locks the rent for the term unless the lease itself contains an escalation clause, so the notice's real function there is at renewal: it tells the tenant what the rent will be if the lease renews or rolls into a month-to-month arrangement. Serve it far enough ahead that the tenant can decide before any non-renewal deadline in the lease.

Whatever the state allows, federal and state law forbid two motives. Retaliation: an increase that answers a tenant's complaint to code enforcement, repair request, or organizing activity can be voided and can support damages, and timing alone often creates the presumption. Discrimination: the increase must not single out tenants by race, national origin, familial status, disability, or any other protected class. Consistent criteria applied to the whole building are what a landlord shows when challenged.

The notice itself is short and factual: the parties and the property, the current rent, the new rent, the effective date, and how the tenancy otherwise continues unchanged. No justification is legally required in most markets, but a one-line business reason (taxes, insurance, maintenance costs) keeps the relationship professional. Deliver it the way the lease's notice clause requires and keep dated proof; the effective date is measured from delivery.

How to complete a rent increase notice in Colorado, step by step

Here is the sequence that makes a Colorado rent increase stick: right authority, right amount, right date, right delivery.

  1. Check what governs the tenancy. Read the lease first. A fixed term locks the rent until renewal unless an escalation clause says otherwise; a month-to-month tenancy can be re-priced with proper notice. The lease's own notice clause can require more than the statute, never less.
  2. Verify the ceiling before picking the number. Colorado limits the increase: no dollar limit, but rent may not be increased more than once in any 12-month period (Colo. Rev. Stat. 38-12-702). Confirm the current year's figure before writing the new rent.
  3. Compute the effective date. Give 60 days' advance written notice (Colo. Rev. Stat. 38-12-701). Count from delivery, land the new rent on the first day of a rental period, and add margin for the delivery method.
  4. Write the notice with exact numbers. Parties, property, current rent, new rent, effective date, and a statement that all other terms continue unchanged. Address every tenant named on the lease and sign it.
  5. Deliver it with proof. Use the method the lease's notice clause requires (hand delivery with a witness, certified mail, or the statute's service method) and keep dated proof. An increase the tenant can plausibly deny receiving is an increase a court will not enforce.
  6. Handle the response. The tenant can accept (often silently, by paying), negotiate, or give their own move-out notice. If the tenant stays past the effective date and pays the old rent, respond promptly in writing; acquiescing to short payments can waive the increase. Keep the notice and the proof of delivery with the lease file.

Colorado rent increase notice FAQ

How much notice does a landlord have to give to raise rent in Colorado?

60 days' advance written notice (Colo. Rev. Stat. 38-12-701). The lease can require more notice than the statute; it can never validly require less.

Is there a limit on how much rent can be raised in Colorado?

Yes: no dollar limit, but rent may not be increased more than once in any 12-month period (Colo. Rev. Stat. 38-12-702).

Can a landlord raise rent in the middle of a lease in Colorado?

Not unless the lease itself allows it. A fixed-term lease locks the rent for the term; the increase takes effect at renewal or when the lease rolls into a month-to-month tenancy. On a month-to-month arrangement, the rent can change with proper advance written notice, effective at the start of a rental period.

What can a tenant do about a rent increase in Colorado?

Three lawful paths: accept it (paying the new rent is acceptance), negotiate before the effective date, or give the required move-out notice and leave before the new rent starts. An increase served with short notice does not bind until the full period has run, and an increase that retaliates against a complaint or discriminates against a protected class can be challenged.
