Oklahoma does not cap how large a residential security deposit may be. Unused deposit plus an itemized list is generally due within 45 days (Okla. Stat. tit. 41, § 115). Missing that deadline can cost double damages.
A month-to-month tenancy generally takes 30 days’ written notice (Okla. Stat. tit. 41, § 111).
Except in an emergency, the landlord must give at least one day’s notice before entering (Okla. Stat. tit. 41, § 128).
A Oklahoma rent increase should be in writing. Many landlords use at least the same notice they would use to end a month-to-month tenancy. A month-to-month tenancy generally takes 30 days’ written notice (Okla. Stat. tit. 41, § 111). The lease may require more. Local rent-control rules can cap the amount even when the notice period is met.
