Oklahoma Landlord-Tenant Laws
Oklahoma Security deposits
Oklahoma sets no cap on security deposits, but landlords must keep every deposit in an escrow account at a federally insured financial institution located in Oklahoma, and must return the balance, without interest, within 45 days after the tenancy ends, possession is delivered, and the tenant makes a written demand for the money.
Oklahoma Rent increase notice
Oklahoma has no statute requiring advance notice of a rent increase — the 30-day convention for month-to-month tenancies is derived from 41 O.S. 111(A), which lets either party end a month-to-month or at-will tenancy on 30 days' written notice (7 days for shorter periods), so a landlord proposing higher rent is effectively offering new terms the tenant can decline by leaving.
Oklahoma Late fees
Oklahoma sets no cap on residential late fees and mandates no grace period — rent is 'payable at the time and place agreed to by the parties' (41 O.S. 109(B)), so a lease-based late fee can begin accruing the day after rent is due.
Oklahoma Entry notice
Oklahoma landlords must give tenants at least one day's notice before entering a rental for inspections, repairs, services, or showings, and may enter only at reasonable times — with no notice needed in an emergency or where giving it is impracticable.
How this record was verified: Direct read of statute text on two official state hosts: oscn.net (Oklahoma State Courts Network) section pages for 41 O.S. 115, 128, 124, 111, 109, 103, 104, and 131 and for 11 O.S. 14-101.1, cross-checked verbatim against the Oklahoma Legislature's complete-title PDFs (oklegislature.gov/OK_Statutes/CompleteTitles/os41.pdf and os11.pdf), downloaded and text-extracted locally. Every load-bearing figure matched word-for-word across both hosts: the escrow-account requirement, the misappropriation penalty (county jail up to 6 months plus fine up to twice the amount misappropriated), the 45-day return clause with its three triggers (termination of tenancy, delivery of possession AND written demand by the tenant), the 6-month demand window with reversion to the landlord, 'without interest', the 30-day/7-day termination notices of 111(A)-(B), the 'one (1) day's notice ... reasonable times' entry rule of 128(C), and the 5-day pay-or-quit window of 131(B). Negative checks run against the full extracted Title 41 text (both the ORLTA and the pre-1978 provisions): no deposit cap, no deposit interest, no late-fee amount/structure/grace regulation anywhere in the title. Pending-bill check 2026-07-09 via the Legislature's own subject index (Session 2600) plus LegiScan/BillTrack50 statuses: the 60th Legislature's 2026 Regular Session adjourned sine die, killing SB1296 (7%+CPI rent cap with 90-day notice; dead 2026-05-14, never heard in committee) and HB3389 (pet deposit/fee regulation; died in House Rules); no enacted 2026 law touches the four topics.
