Kansas Landlord-Tenant Laws
Kansas Security deposits
Kansas caps security deposits at one month's rent for an unfurnished rental, 1½ months' rent if the unit comes furnished, plus up to an extra half month's rent as a pet deposit when the lease allows pets.
Kansas Rent increase notice
Kansas has no statute requiring advance notice of a rent increase — the 30-day figure quoted for month-to-month tenancies is derived from K.S.A. 58-2570(b), which lets either party end a month-to-month tenancy by written notice effective on a rent-paying date at least 30 days after the other side receives it, so a landlord proposing higher rent is effectively offering new terms the tenant can decline by leaving.
Kansas Late fees
Kansas sets no cap on residential late fees and mandates no grace period — the Residential Landlord and Tenant Act never mentions late fees, and rent is payable without demand or notice at the time the lease fixes (K.S.A. 58-2545(c)), so a lease-based fee can start accruing the day after rent is due.
Kansas Entry notice
Kansas requires only 'reasonable notice' before a landlord enters a rental — no statute fixes a number of hours, and entry must happen at reasonable hours of the day (K.S.A. 58-2557).
How this record was verified: Direct read of statute text on the official Kansas Office of Revisor of Statutes site (ksrevisor.gov), each load-bearing section fetched twice by independent methods (WebFetch page read plus raw curl of the same official page, all figures reconciled verbatim): 58-2550 (1-month/1.5-month/half-month pet caps, 14-day and 30-day return clocks, 1.5x penalty), 58-2548 (5-day joint inventory), 58-2557 (reasonable notice/reasonable hours entry), 58-2570 (7-day/30-day/15-day termination notices), 58-2565(b) (30-day absence entry, 10-day abandonment presumption), 58-2564(b) (3-day nonpayment cure), 58-2563 (1.5 months' rent ouster remedy), and 12-16,120 (express local rent-control preemption). Negative checks run against the full Residential Landlord and Tenant Act: all 34 sections (58-2540 through 58-2573) downloaded and searched — no late-fee, grace-period, deposit-interest, escrow/separate-account, or rent-increase-notice provision exists. Pending-bill check 2026-07-11 on kslegislature.gov: 2025-26 biennium adjourned sine die 2026-04-11; HB 2666 (late-fee restrictions), SB 482 (condemned-unit deposit return), and HB 2768 (split rent payments) all died in committee; enacted Sub HB 2357 (eviction expungement) and SB 391 (voucher-mandate preemption) do not affect these four topics.
