Kansas Lease Agreement Requirements: Deposits, Late Fees, and Repairs

A Kansas lease agreement is the written contract that sets the terms under which a tenant rents a residential property from a landlord, and in Kansas it operates under two overlapping statutes: the original Residential Landlord and Tenant Act starting at KSA 58-2540, and a newer set of provisions starting at KSA 58-25,100 that updated security deposit caps and termination notice rules. Anyone signing in 2026 should read the lease with both frameworks in mind, because the newer provisions now control several parts of new agreements.¹

One default matters before you write anything: a Kansas tenancy is month-to-month unless the written agreement specifies otherwise.¹ Hand over the keys without a written lease and both sides land in a month-to-month arrangement with fewer protections. Put the terms on paper.

What the Lease Should Cover

At a minimum, a Kansas residential lease should identify:

The names of the landlord (or property manager) and every adult tenant.
The specific street address or legal description of the unit.
The lease term, whether that is a fixed period or a month-to-month arrangement.
The monthly rent amount, the due date, and how it should be paid.
The total security deposit, broken down by category if there is a base deposit plus a pet deposit.
The late fee amount and when it triggers, since Kansas sets no statutory cap.

Security Deposit Limits

Kansas caps security deposits, and which cap governs depends on which framework applies to the lease. The original act at KSA 58-2550 breaks the limits down by unit type:

Unfurnished unit: no more than one month’s rent.
Furnished unit: no more than one and a half months’ rent.
Pet deposit: an additional half-month’s rent when the lease allows pets.

The ceiling under that framework for a tenant with a pet in a furnished unit works out to two months’ rent.²

The newer provisions at KSA 58-25,108 collapse those categories into a single cap of two months’ rent for all security deposits, regardless of furnishing or pets. For new leases signed in 2026, that two-month ceiling is the controlling limit. Collecting more than the statutory maximum exposes a landlord to liability under whichever framework applies.

Getting the Deposit Back

After a tenancy ends, a Kansas landlord has 30 days from the tenant vacating, returning possession, and demanding the deposit to return any remaining balance. If part of the deposit is being kept for damages or unpaid rent, the landlord must give the tenant an itemized written statement of the charges.²

If the tenant does not demand the deposit within 30 days after the tenancy ends, the landlord must mail whatever is owed to the tenant’s last known address. A landlord who wrongfully withholds part or all of the deposit can be liable for the amount owed plus one and a half times the amount wrongfully withheld as a penalty.²

Move-In Inventory and Lead Disclosure

Kansas requires a joint move-in inventory within five days of the tenant taking possession. The landlord or a representative walks through the unit with the tenant, and together they document the condition of every room along with any furnished appliances. Both parties sign duplicate copies and the tenant keeps one.³ That signed inventory is the baseline for any later deposit dispute. Skipping it almost always hurts the landlord, because proving damage occurred during the tenancy is much harder without one.

For any property built before 1978, federal law adds a lead-based paint requirement. Before the lease is signed, the landlord must provide a lead warning statement, a copy of the EPA pamphlet “Protect Your Family From Lead in Your Home,” and any known information about lead-based paint or hazards in the unit.⁴ Noncompliance carries significant federal penalties.

Clauses That Won’t Hold Up

Under KSA 58-2547, several types of lease clauses are unenforceable in Kansas even if both parties sign, and a landlord who knowingly includes them can owe the tenant actual damages. Void provisions include any that:

Waive rights the landlord-tenant act gives the tenant.
Authorize a confession of judgment against the tenant.
Require either party to pay the other’s attorney fees.
Remove or limit either party’s liability for negligence or other wrongful acts.

The one narrow exception allows a tenant to agree to limit the landlord’s liability for fire, theft, or breakage specifically in common areas.⁵

Late Fees

Kansas has no statutory cap on late fees in residential leases. The self-service storage act limits late charges for storage units, but there is no parallel restriction for houses or apartments. The lease itself is the only document setting the amount and the trigger. If the lease says rent is due on the first and late on the second, the late fee starts on the second, with no required grace period.

A court could still refuse to enforce a late fee that is wildly disproportionate to the landlord’s actual costs on unconscionability grounds, but there is no bright-line dollar limit in the statutes. Read this section closely before signing.

Repair Duties and Landlord Entry

Kansas landlords must keep electrical, plumbing, heating, ventilation, and air-conditioning systems in safe working order. They must also comply with applicable building and housing codes, maintain common areas with reasonable care, provide running water and reasonable amounts of hot water, supply reasonable heat unless the tenant controls heating through a direct utility connection, and arrange for trash removal from common-use receptacles.⁶ Tenants have their own obligations under KSA 58-2555 to keep the unit clean and safe, use appliances reasonably, and handle their own trash.⁷ Repairs caused by tenant misuse fall on the tenant.

A landlord may enter for inspections, repairs, agreed improvements, or to show the unit, but outside of emergencies must give reasonable notice and enter only at reasonable hours. The statute does not define reasonable notice as a specific number of hours, though 24 hours is the widely accepted convention in Kansas practice. The one exception is an extreme hazard involving potential loss of life or severe property damage, where the landlord can enter without consent or notice. The statute also expressly bars using the right of access to harass the tenant.⁸ If the lease sets a specific notice period, that contractual term controls; if the lease is silent, the statutory “reasonable” standard applies.

Ending a Month-to-Month Tenancy

Notice requirements again depend on the framework. Under the newer provisions at KSA 58-25,105, either party must give at least 60 days’ written notice to end a month-to-month tenancy unless the lease specifies a different period.¹ The older act at KSA 58-2570 requires only 30 days’ written notice, with the termination date falling on a periodic rent-paying date.⁹

A tenant in the military who needs to end a month-to-month tenancy because of military orders can do so with 15 days’ written notice under the older act.⁹ Federal protections under the Servicemembers Civil Relief Act may add rights for active-duty service members breaking fixed-term leases.

Making the Lease Binding

A Kansas lease becomes binding when it is signed by the landlord and every adult tenant. Electronic signatures carry the same weight as ink under the Kansas Uniform Electronic Transactions Act, and no notarization is required for a standard residential lease.¹⁰

Kansas also addresses what happens when one party never signs. If a landlord accepts rent from a tenant who signed and delivered a lease, the lease takes effect as though the landlord had signed. The reverse holds too: a tenant who takes possession and pays rent on a lease the landlord signed is bound even without a signature. Any unsigned lease that would otherwise run longer than one year is capped at one year under this rule.¹¹ Get signatures from both sides and keep a copy. Implied acceptance creates ambiguity that helps no one.
