Oklahoma Lease Amendment

This Lease Amendment is built with Oklahoma as the governing state. These are the Oklahoma landlord-tenant rules that most often bear on it, with the statute for each.

Oklahoma rules at a glance

Oklahoma rules for a Lease Amendment
Rent-increase notice	No specific statute; a month-to-month change needs the 30-day termination notice41 O.S. §111(A)
Rent increases	No statute sets a rent-increase notice period. Rent can’t be raised mid-term on a fixed-term lease unless the lease allows it; for a month-to-month tenancy, a change of terms should be given with at least the 30 days’ written notice needed to end the tenancy (§111(A)).
Rent control	Oklahoma has no rent-control law, so the market sets the rent.
Security deposit limit	No statutory cap; must be held in an Oklahoma escrow account41 O.S. §115(A)
Deposit return	45 days after termination, delivery of possession and the tenant’s written demand41 O.S. §115(B)
Itemized statement	Any deductions for rent or damages must be itemized in a written statement delivered by mail, return receipt requested, or handed to the tenant in person if they can reasonably be found (§115(B)).

Security deposits in Oklahoma

Oklahoma puts no dollar limit on a security deposit. What it regulates is where the money sits and how it comes back: every damage or security deposit must be kept in an escrow account for the tenant, maintained in Oklahoma with a federally insured financial institution. Misappropriating it is a crime punishable by up to six months in county jail and a fine of up to twice the amount taken (41 O.S. §115(A)).

Three-part trigger — The landlord must return the balance, without interest, within 45 days after the tenancy ends, the tenant delivers possession, and the tenant makes a written demand for the deposit. The clock doesn’t start until all three have happened (§115(B)).
Itemized statement — Any deductions for rent or damages must be itemized in a written statement delivered by mail, return receipt requested, or handed to the tenant in person if they can reasonably be found (§115(B)).
Six-month demand window — If the tenant makes no written demand within six months after the tenancy ends, the deposit reverts to the landlord and the tenant’s interest in it terminates (§115(B)).
Not last month’s rent — Unless the lease says otherwise, a tenant can’t apply the deposit to the last month’s rent or use it in place of rent at any time (§115(F)).
If the landlord doesn’t comply — The tenant may recover the deposit and any prepaid rent, plus any other damages available under the Act (§115(E), (G)). Oklahoma’s statute does not add a double-damages penalty for late return.
Sale of the property — When the landlord’s interest ends, deposits must either be returned to the tenants or transferred to the successor, with written notice of the transferee’s name and address (§115(C)).

Rent, late fees & rent increases

Rent is payable at the time and place the parties agree. If the lease is silent, it’s payable at the dwelling unit at the start of each term of a month or less, and monthly in advance on longer terms (41 O.S. §109).

Late fees — Oklahoma has no late-fee statute. In Sun Ridge Investors, Ltd. v. Parker, 1998 OK 22, the Oklahoma Supreme Court treated a late charge as liquidated damages and struck a $5-per-day charge stacked on a $20 late fee as an unenforceable penalty. A late fee should be a reasonable estimate of the landlord’s actual cost of late payment and must be written into the lease.
Rent increases — No statute sets a rent-increase notice period. Rent can’t be raised mid-term on a fixed-term lease unless the lease allows it; for a month-to-month tenancy, a change of terms should be given with at least the 30 days’ written notice needed to end the tenancy (§111(A)).
Rent control — Oklahoma has no rent-control law, so the market sets the rent.
Occupancy limits — A lease may set reasonable limits on use and occupancy; two persons per bedroom is presumed reasonable, not counting children born to the tenants during the lease (§117(B)–(C)).

Oklahoma Lease Amendment FAQs

How much can a landlord charge for a security deposit in Oklahoma?

There is no statutory cap — the lease sets the amount. Oklahoma instead requires the deposit to be held in an escrow account with a federally insured financial institution in Oklahoma, and misappropriating it is a crime (41 O.S. §115(A)).

How long does a landlord have to return a security deposit in Oklahoma?

45 days after the tenancy ends, the tenant delivers possession, and the tenant makes a written demand — all three. Deductions must be itemized in writing, sent by mail with return receipt requested or delivered in person. If the tenant doesn’t demand the deposit in writing within six months, it reverts to the landlord (41 O.S. §115(B)).

Is there a limit on late fees in Oklahoma?

No statute caps late fees. Under Sun Ridge Investors, Ltd. v. Parker, 1998 OK 22, a late fee is treated as liquidated damages and must be a reasonable estimate of the landlord’s actual loss; an excessive or stacked daily fee can be struck as a penalty.
