Grounds

An unconditional notice offers no chance to fix the problem, and is only available for conduct that cannot be cured — nuisance, waste, illegal activity, or a repeat of a breach already cured. If the tenant could fix it, use Cure or Quit instead.

Ending the tenancy

This is a no-cause termination. Many cities require just cause, and some require relocation assistance. Verify locally before serving.

Where Colorado landlords get this wrong

Local rules that sit on top of Colorado law

A notice that is perfect under the state statute still fails if it ignores the city. These are the jurisdictions with material local overlays for this kind of notice.

Denver, Aurora, Boulder
Local just-cause and relocation-payment requirements sit on top of the state framework introduced in 2024. Verify with the city before serving a no-fault notice.

Common questions

How long is the notice period for a 10-day notice to pay rent or quit in Colorado?
10 days, under Colo. Rev. Stat. § 13-40-104(1)(e). Colorado requires a 10-day demand for compliance or possession. Under HB 24-1098 a nonpayment case must give the tenant a meaningful opportunity to cure within that 10-day window.
Does service by mail change the Colorado notice period?
Colorado does not add days for service by mail, but the notice must still be served by a method the statute allows.
Can the rental agreement change the Colorado notice period?
A lease can lengthen a cure period, and where it does, the longer period controls. Enter your lease's period in the generator and the deadline is recomputed for you. A lease cannot shorten a period the statute sets.
Is this Colorado 10-day notice to pay rent or quit legally binding?
RentDemand generates a self-help document from the statute cited on its face. It is not legal advice and it is not a substitute for a lawyer in Colorado, particularly if the tenancy is contested or the unit is covered by a local ordinance.

Questions landlords ask at 11pm

Is this legal advice?
No. RentDemand is not a law firm and does not provide legal advice. It assembles a self-help document from the statute shown on the notice and computes your deadline. For anything contested, hire a lawyer in your state — the notice you generate here is the document you hand them.
How is this different from a free template?
A free template gives you the same paragraph in every state with blank day counts. RentDemand knows that a Florida pay-or-quit skips weekends and holidays, that Virginia gives 21 days to cure but only 5 to pay, that North Carolina terminates a month-to-month tenancy in 7 days, and that Georgia has no cure period at all. It also computes the actual date the period ends.
What if my lease sets a different period?
Change the number. The notice period field is pre-filled with the statutory default and is yours to edit — a lease can lengthen a cure period, and the longer period then controls.
Do I get a PDF?
You get a print-ready document with correct 8.5×11 pagination. Click Unlock and your browser's print dialog opens; choose Save as PDF. That gives you a cleaner file than most generators produce, because the browser does the typesetting.
What if I serve it wrong?
Service is where these notices fail. Every document includes a proof-of-service block with the recognised methods for your state, and the day-of-service exclusion is already built into the deadline. If you serve by mail, tick the box and the mailing extension is added automatically.
