The written notice Colorado requires before you can file an eviction — 10 days for non-payment under C.R.S. §§ 13-40-104, 13-40-107, 13-40-10... — with the balance, deadline date and delivery record filled in from the tenant's ledger.
The reason changes the wording and the deadline. Pick the situation; the period on each card is Colorado's minimum — your lease can require more, never less.
C.R.S. §§ 13-40-104, 13-40-107, 13-40-107.5C.R.S. §§ 13-40-104, 13-40-107, 13-40-107.510 days (C.R.S. §§ 13-40-104, 13-40-107, 13-40-107.5). Your lease can require more notice than the statute, never less.
A lease can lengthen the period. Whether it can shorten it depends on the state — Colorado's rule is above; when the lease is silent, the statutory period applies.
From the day after delivery, and the notice should state the deadline as a date. Where Colorado counts business or judicial days, weekends and court holidays are skipped.
You file the eviction in the local court. Filing before the notice period ends gets the case dismissed, so keep the delivery date.
Only if the lease agrees to electronic delivery; otherwise use hand delivery, mail or posting where Colorado permits it. The in-app notice emails the tenant and logs it, and prints for hand delivery.

Notice periods are Colorado's statutory minimums as of 2026, reviewed against Colorado Revised Statutes, Title 38, Article 12 (Tenants and Landlords). General information for landlords, not legal advice; local rules — and the CARES Act 30-day notice for covered properties — can add requirements.
