10 of the 10 rules below carry a statute citation that was read at the official source (most recently October 2026), with the controlling text quoted. The rest are conservative reference values from Aptoria's compliance data and are labeled unverified.
Security deposit size: No statewide statutory cap on the amount of a security deposit. 41 O.S. § 115 regulates custody (deposit must be held in an escrow account in an Oklahoma federally insured institution; misappropriation is a misdemeanor punishable by up to six months in county jail and a fine of up to twice the amount taken) and return, but sets no maximum amount. (41 O.S. § 115, confirmed 2026-10). Returning the deposit: Within 45 days after the later of termination of the tenancy, delivery of possession, AND the tenant's written demand, return the balance of the deposit (without interest) less amounts applied to unpaid rent or damages. If the tenant makes no written demand within six months after termination, the deposit reverts to the landlord. Landlord has no duty to return absent the tenant's written demand. (41 O.S. § 115(B), confirmed 2026-10).
How Oklahoma treats the landlord's core obligations
Late fees: No statewide statutory cap on late fees and no mandatory grace period. The Residential Landlord and Tenant Act's rent section (41 O.S. § 109) addresses only amount, time and place of payment; late charges are left to the rental agreement (general unconscionability/penalty limits apply). (41 O.S. § 109, confirmed 2026-10). Application fees: No statewide cap on rental application fees; Title 41 (Residential Landlord and Tenant Act) contains no application-fee section. (41 O.S. §§ 101–136 (no application-fee section), confirmed 2026-10).
Nonpayment notice: Landlord may terminate for nonpayment if the tenant fails to pay within 5 days after written notice of the landlord's demand for payment. The demand for past-due rent is deemed a demand for possession; no separate notice to quit is required. The notice may be given before or after filing a rent-recovery action under subsection A. (41 O.S. § 131(B), confirmed 2026-10). Rent increases: No statutory notice period for a rent increase. On a month-to-month tenancy an increase is effected by terminating on the old terms with at least 30 days' written notice (§ 111(A)); the Residential Landlord and Tenant Act has no rent-increase section. (41 O.S. § 111(A); 41 O.S. §§ 101–136 (no rent-increase section), confirmed 2026-10). Ending a month-to-month tenancy: Month-to-month or tenancy-at-will: written notice at least 30 days before the effective termination date. Tenancies shorter than month-to-month: at least 7 days' written notice. (41 O.S. § 111(A)-(B), confirmed 2026-10). Entry: At least one day's notice of intent to enter, and entry only at reasonable times, except in an emergency or when notice is impracticable. Landlord may enter without consent in an emergency. (41 O.S. § 128(B)-(C), confirmed 2026-10).
Oklahoma has no statewide rent regulation on file, so any cap on increases would come from a local ordinance. Source-of-income protection is not on file statewide, although cities and counties can add it. Card surcharges on rent: allowed within card-network limits. Managing property for others for compensation generally requires a state license: State real estate broker license required for property management for others — confirm with state commission.
Security deposits
What Oklahoma allows a landlord to collect up front, how it must be held, and the deadline and paperwork for returning it.
Security deposit limit
Source-confirmed 2026-10
No statewide statutory cap on the amount of a security deposit. 41 O.S. § 115 regulates custody (deposit must be held in an escrow account in an Oklahoma federally insured institution; misappropriation is a misdemeanor punishable by up to six months in county jail and a fine of up to twice the amount taken) and return, but sets no maximum amount.
“the landlord shall return the balance of the security deposit without interest to the tenant within forty-five (45) days after the termination of tenancy, delivery of possession and written demand by the tenant”
Excerpt from the cited source as read on the date shown.
it contains no amount limit. Third-party sites claiming a '2 months' cap could not be matched to any statutory text.
Reference value in Aptoria's compliance data: “No statewide cap”. Where it differs from the statute above, the statute controls; differences found in review are logged for an engine update.
The maximum a landlord may collect up front as security against unpaid rent or damage, usually expressed as a multiple of one month's rent. Separate pet, key or cleaning deposits often count toward the same limit.
Deposit return deadline
Source-confirmed 2026-10
Within 45 days after the later of termination of the tenancy, delivery of possession, AND the tenant's written demand, return the balance of the deposit (without interest) less amounts applied to unpaid rent or damages. If the tenant makes no written demand within six months after termination, the deposit reverts to the landlord. Landlord has no duty to return absent the tenant's written demand.
“If the tenant does not make such written demand of such deposit within six (6) months after termination of the tenancy, the deposit reverts to the landlord.”
Excerpt from the cited source as read on the date shown.
Reference value in Aptoria's compliance data: “45 days after move-out”. Where it differs from the statute above, the statute controls; differences found in review are logged for an engine update.
The window after the tenant vacates in which the landlord must refund the deposit or deliver an itemized statement of deductions. Missing the deadline is the most common way a landlord forfeits the right to keep any part of the deposit.
Separate pet deposit
Source-confirmed 2026-10
No statewide cap on security deposits and no statute addressing pet deposits; 41 O.S. § 115 neither authorizes nor prohibits a separate pet deposit, so a pet deposit may be charged by agreement. Any pet deposit is a 'damage or security deposit' that must be held in an Oklahoma escrow account and returned under § 115.
“Any damage or security deposit required by a landlord of a tenant must be kept in an escrow account for the tenant, which account shall be maintained in the State of Oklahoma with a federally insured financial institution.”
Excerpt from the cited source as read on the date shown.
Reference value in Aptoria's compliance data: “Permitted”. Where it differs from the statute above, the statute controls; differences found in review are logged for an engine update.
Whether a refundable pet deposit can be collected on top of the security deposit. Even where it is permitted, the combined amount usually has to stay inside the overall deposit limit.
In practice
• Hold the deposit the way the statute requires (separate or escrow account where applicable) and record the account in the file.
• Document move-in condition with a dated, photographed inventory the tenant can sign; it is the only evidence that supports a later deduction.
• Send the itemized statement and any refund by a trackable method, and keep the receipts or estimates behind every deduction.
Rent, late fees and application fees
The fees a Oklahoma lease can charge, the statutory ceilings that override the lease, and whether rent increases are regulated statewide.
Late fees
Source-confirmed 2026-10
No statewide statutory cap on late fees and no mandatory grace period. The Residential Landlord and Tenant Act's rent section (41 O.S. § 109) addresses only amount, time and place of payment; late charges are left to the rental agreement (general unconscionability/penalty limits apply).
“Rent shall be payable at the time and place agreed to by the parties.”
Excerpt from the cited source as read on the date shown.
no late-fee section exists in the Act.
Reference value in Aptoria's compliance data: “No statewide cap (reasonableness standard)”. Where it differs from the statute above, the statute controls; differences found in review are logged for an engine update.
Any statutory ceiling on the fee for late rent and any mandatory grace period before it can be charged. Where there is no statutory cap, courts still strike fees they find punitive rather than a reasonable estimate of the landlord's cost.
Application fee limit
Source-confirmed 2026-10
No statewide cap on rental application fees; Title 41 (Residential Landlord and Tenant Act) contains no application-fee section.
Reference value in Aptoria's compliance data: “No statewide cap”. Where it differs from the statute above, the statute controls; differences found in review are logged for an engine update.
A cap on what an applicant can be charged to apply, sometimes limited to the actual cost of screening and sometimes prohibited outright. Fee receipts and refund rules usually travel with the cap.
Statewide rent regulation
Source-confirmed 2026-10
(b) Statewide preemption: no municipal governing body may regulate the amount of rent charged for privately owned single-family, multi-unit residential, or commercial rental property (11 O.S. § 14-101.1(A)). Exceptions (subsection B): municipally owned property, agreements setting subsidized rents, and CDBG-assisted properties. No statewide rent-increase cap.
“No municipal governing body may enact, maintain, or enforce any ordinance or resolution which regulates the amount of rent”
Excerpt from the cited source as read on the date shown.
Located via the OSCN Title 11 index (entry '14-101.1.
Reference value in Aptoria's compliance data: “No statewide rent regulation (check local ordinances)”. Where it differs from the statute above, the statute controls; differences found in review are logged for an engine update.
Whether a statewide law caps annual rent increases or whether rent control exists for covered units. Local ordinances can add limits even where the state has none.
In practice
• State the late fee, the grace period and the application fee in the lease in dollars or a clear percentage; a fee that is not in the lease is rarely enforceable.
• Never charge above the statutory cap even when the lease says more; the excess is unenforceable and can expose the landlord to penalties.
• Keep fee calculations in the ledger so a tenant, a court or an auditor can reproduce them from the rent roll.
Notices, rent increases and termination
How much written notice Oklahoma requires before a rent increase, before ending a month-to-month tenancy, and before filing for nonpayment.
Rent-increase notice
Source-confirmed 2026-10
No statutory notice period for a rent increase. On a month-to-month tenancy an increase is effected by terminating on the old terms with at least 30 days' written notice (§ 111(A)); the Residential Landlord and Tenant Act has no rent-increase section.
Absence confirmed against the Title 41 section index; the 30-day figure is the termination notice, not a rent-increase rule.
Reference value in Aptoria's compliance data: “30 days”. Where it differs from the statute above, the statute controls; differences found in review are logged for an engine update.
The written notice a landlord must give before a rent increase takes effect on a periodic (month-to-month) tenancy. Fixed-term leases generally cannot be changed mid-term.
Month-to-month termination notice
Source-confirmed 2026-10
Month-to-month or tenancy-at-will: written notice at least 30 days before the effective termination date. Tenancies shorter than month-to-month: at least 7 days' written notice.
“at least thirty (30) days before the date upon which the termination is to become effective”
Excerpt from the cited source as read on the date shown.
Reference value in Aptoria's compliance data: “30 days”. Where it differs from the statute above, the statute controls; differences found in review are logged for an engine update.
The notice a landlord must give to end a periodic tenancy without cause. Some jurisdictions require longer notice for long-term tenants or require a stated cause.
Pay-or-quit notice
Source-confirmed 2026-10
Landlord may terminate for nonpayment if the tenant fails to pay within 5 days after written notice of the landlord's demand for payment. The demand for past-due rent is deemed a demand for possession; no separate notice to quit is required. The notice may be given before or after filing a rent-recovery action under subsection A.
“A landlord may terminate a rental agreement for failure to pay rent when due, if the tenant fails to pay the rent within five (5) days after written notice of landlord's demand for payment”
Excerpt from the cited source as read on the date shown.
'Demand for past due rent is deemed a demand for possession of the premises' also confirmed.
Reference value in Aptoria's compliance data: “5 days”. Where it differs from the statute above, the statute controls; differences found in review are logged for an engine update.
The notice a tenant must receive for nonpayment before the landlord can file for possession, and the time the tenant has to pay in full and cure. This is the step most often done wrong in an eviction.
In practice
• Serve notices in the form and by the method the statute names, and keep proof of service with the dated notice.
• Count notice periods the way the statute counts them (calendar days, business days, or "before the next rent due date") and build in a margin.
• Treat a notice to a possibly rent-regulated or subsidized unit as a legal check, because longer periods and extra content requirements usually apply.
Landlord entry
When a Oklahoma landlord may enter an occupied unit and how much notice the tenant must receive.
Non-emergency entry notice
Source-confirmed 2026-10
At least one day's notice of intent to enter, and entry only at reasonable times, except in an emergency or when notice is impracticable. Landlord may enter without consent in an emergency.
“the landlord shall give the tenant at least one (1) day's notice of his intent to enter and may enter only at reasonable times.”
Excerpt from the cited source as read on the date shown.
Reference value in Aptoria's compliance data: “24 hours”. Where it differs from the statute above, the statute controls; differences found in review are logged for an engine update.
The advance notice required before a landlord enters an occupied unit for repairs, inspections or showings. Emergencies are the usual exception.
In practice
• Give written notice with the date, a reasonable time window and the purpose, and log the entry afterwards.
• Emergencies are the only common exception; document what made the entry urgent.
• A pattern of unannounced entries is a common basis for tenant complaints and counterclaims.
Payments, fair housing and licensing
Operational rules that sit outside the landlord-tenant act but decide how rent can be collected, who can be screened out, and who may manage for others.
Card surcharges on rent
Allowed within card-network limits
Returned-payment (NSF) fee
No statewide statutory cap on file
Source-of-income protection
No statewide protection on file
Local ordinances can extend protection beyond the statewide rule.
Property-management licensing
License generally required to manage for others
State real estate broker license required for property management for others — confirm with state commission.

Is source of income a protected class in Oklahoma?
No statewide source-of-income protection is on file for Oklahoma, but cities and counties can adopt it. Check local law before refusing a voucher or benefit income, and apply any screening criteria consistently.
Can a Oklahoma landlord add a surcharge for paying rent by card?
Allowed within card-network limits. Where a surcharge is allowed, it must still follow card-network rules and be disclosed before payment.
How this page was verified
Every rule is shown in one of two states. “Source-confirmed” means an editor opened the official statute page named next to the rule on the date shown, read the controlling text, and recorded the excerpt you see; the excerpt is quoted verbatim so you can check it. “Reference value” means Aptoria's compliance engine applies a conservative number for this rule, but nobody has yet tied it to a specific statute section on this page, so it must be checked before you rely on it.
This page meets Aptoria's evidence floor for publication (10 source-confirmed rules and 2 fetched official sources). Statutes change; local ordinances can be stricter; the facts of a tenancy change the result.
