Colorado Landlord-Tenant Laws
Colorado Security deposits
Colorado caps security deposits at two months' rent — a rule in force since August 2023 — and layers on one of the country's most tenant-protective return regimes after a major 2025 rewrite took effect on January 1, 2026: deposits are due back within 30 days (a lease can stretch that to 60 at most), any retention needs a written statement of the exact reasons limited to four permitted causes, and tenants can demand the landlord's photos, receipts, invoices, and estimates within 14 days.
Colorado Rent increase notice
Colorado limits how often rent can rise — no more than once in any 12-month period of consecutive occupancy, no matter what kind of lease the tenant has or whether anything is in writing — but sets no limit on how much.
Colorado Late fees
Colorado has one of the strictest late-fee statutes in the country: no fee at all unless rent is at least seven calendar days late, and the fee is capped at the greater of $50 or 5% of the past-due amount — note it keys to the amount actually unpaid, not the full month's rent.
Colorado Entry notice
Colorado has no general statute requiring advance notice before a landlord enters a rental home — notice periods, purposes, and timing are governed by the lease, so a well-drafted entry clause matters more here than in most states.
How this record was verified: Colorado's official CRS text is published via LexisNexis without stable deep links (GA-class sourcing situation), so verification pairs official session-law sources with current code mirrors: the HB25-1249 enrolled act read verbatim from the official leg.colorado.gov PDF (full text extracted) and re-confirmed against the official bill-page summary (independent reads matched on the 30-day return deadline, wrongful-retention standard, 125% presumption, walk-through, and carpet/paint rules, and confirmed NO deposit-cap change); official bill pages read for SB23-184 (deposit cap), SB21-173 (late fees), HB21-1121 (rent-increase notice/frequency), HB23-1068 (pet deposits), HB23-1115 (rent-control repeal — died), HB25-1092 and HB26-1047 (died), and SB26-054 (PCOA exemption, eff. 2026-11-01). Statute text quoted from the colorado.public.law and FindLaw mirrors (official: false), with §§ 38-12-105 and 38-12-701 each read on the mirror twice via independent fetches that matched.
