One Kansas City market. Two deposit statutes.
A landlord in almost any other metro learns one security deposit law. A landlord here learns two, and has to know which one applies door by door.
The caps are different. The clocks are different. The penalty for getting it wrong is different. And the line between them runs straight through the middle of the portfolio.
Which deposit law applies to a Kansas City rental?
The law of the state the unit is physically in. Missouri units fall under RSMo § 535.300; Kansas units fall under K.S.A. § 58-2550. Where your office is and where the tenant moves to make no difference.
Missouri: up to two months’ rent, itemized and returned within 30 days, and the tenant may recover twice anything wrongfully withheld. Kansas: one month unfurnished, the balance within 14 days of determining deductions and never more than 30 days after termination, with damages of 1½ times anything wrongfully withheld.
Side by side
The two statutes, in the terms that actually bite.
| Missouri (RSMo § 535.300) | Kansas (K.S.A. § 58-2550) | |
|---|---|---|
| Statute | RSMo § 535.300 | K.S.A. § 58-2550 |
| Deposit cap | Two months' rent. | One month's rent unfurnished; 1½ months furnished; up to another ½ month for pets. |
| Return deadline | 30 days from termination of the tenancy. | 14 days after determining the amount withheld, and no more than 30 days after termination. |
| Itemization | A written itemized list of the damages withheld, inside the same 30 days. | A written, itemized notice of the deductions delivered to the tenant. |
| Move-out inspection | The tenant has the right to be present at the inspection, at the time and date the landlord schedules. | No equivalent move-out right, but K.S.A. § 58-2548 requires a joint move-in inventory. |
| If you get it wrong | The tenant recovers twice the amount wrongfully withheld. | The tenant recovers the amount due plus damages equal to 1½ times the amount wrongfully withheld. |
Statutes are summarized here as of August 2026 and change. This is not legal advice and WalkSpec is not a law firm — read the text yourself at the Missouri Revisor of Statutes and the Kansas Revisor of Statutes, and talk to a Missouri or Kansas attorney about your own units.
The line
Which side of State Line Road is this door on?
The Kansas City metro is a single rental market that happens to straddle a state border. Tenants cross it without noticing. Your deposit template cannot.
Missouri side — RSMo § 535.300
Jackson, Clay, Platte and Cass counties, including:
Kansas City, Missouri · Independence · Lee's Summit · Blue Springs · Raytown · Gladstone · Liberty · North Kansas City · Grandview · Belton · Riverside · Parkville
Kansas side — K.S.A. § 58-2550
Johnson and Wyandotte counties, including:
Overland Park · Olathe · Lenexa · Shawnee · Leawood · Prairie Village · Merriam · Mission · Kansas City, Kansas · Roeland Park · Gardner · De Soto
A manager running units in Raytown and units in Overland Park is running two compliance regimes out of one office. The failure mode is not ignorance of the law — it is a template built around whichever state you started in, quietly reused across the line.
The clock
Thirty days sounds generous until you count backwards.
The deadline starts at termination of the tenancy, not on the day you get around to the unit. Work backwards from there and the realistic budget looks worse than it reads.
A few days pass before anyone walks the unit. The walk produces a camera roll. Trades get called over the next week and quotes trickle back. Somewhere around day twenty, somebody sits down to write the statement — from a memory of a unit they stood in three weeks ago, against a penalty of two times in Missouri and one and a half times in Kansas for withholding something they cannot defend.
That is the whole reason deductions get rounded down. Not generosity — the reasonable fear of a multiplier on a charge nobody wrote the evidence for at the time.
What a compliant statement carries
Six things on the letter, whichever side of the line it goes out from.
- The correct statute for the state the unit is in — not the one your template was built around.
- The right deadline, counted from termination of the tenancy rather than from the day you got to the unit.
- Each deduction itemized: what the damage is, where in the unit it is, and what it cost or is estimated to cost.
- A normal-wear-and-tear call on every line, with the reasoning visible rather than assumed.
- Depreciation applied per component, so a nine-year-old carpet is not charged as a new one.
- The photo behind each line, so the tenant is reading evidence instead of an assertion.
WalkSpec drafts that document from the walk itself, with the Missouri or Kansas deadline and citation already on it depending on where the unit sits — and the same walk produces the make-ready scope for your trades, grouped and sequenced, the same afternoon.
It drafts. It does not send. A person reads every line and approves it, which is exactly where a two-times penalty says the decision should live.
Missouri's inspection right
The tenant can be at the walk. So let them film it.
Missouri gives the tenant the right to be present when you inspect, at the time and date you schedule. Handled as a scheduling problem it is a nuisance: two calendars, one unit, and a clock already running.
Handled as what it actually is — the tenant’s interest in seeing the condition the deductions are based on — there is a simpler answer. Send a walk link. The tenant films the unit on their own phone, in a browser, no app and no account. The link is capture-only and expires: they add to the record and never read a finding or a dollar figure out of it.
You get a complete record without driving to Belton. They get proof of what the unit looked like when they left it. And when the statement arrives, nothing on it is news to either of you.
Kansas City, answered
Deposit questions that come up on both sides of the line.
Deadlines, caps, penalties, and who has to be standing in the unit — for Missouri and Kansas specifically.
How long does a landlord have to return a security deposit in Missouri?
Thirty days from the date the tenancy terminates. Within that window the landlord must either return the full deposit or furnish the tenant a written itemized list of the damages being withheld, under RSMo § 535.300. Missouri also gives the tenant the right to be present at the move-out inspection at the time and date the landlord schedules.
How long does a landlord have to return a security deposit in Kansas?
Kansas runs two clocks under K.S.A. § 58-2550. If the landlord is keeping part of the deposit, the balance goes back within 14 days after the amount of the deductions is determined — and in no event more than 30 days after the tenancy terminates, possession is delivered, and the tenant demands it. The deductions have to be itemized in writing.
How much can a Kansas City landlord charge for a security deposit?
It depends which side of the line the unit is on. Missouri caps a deposit at two months' rent. Kansas caps it at one month's rent for an unfurnished unit, one and a half months for a furnished one, and permits up to another half month for a pet. A landlord operating on both sides of the metro cannot run one deposit policy across the portfolio.
What is the penalty for missing the deposit deadline in Missouri or Kansas?
They differ, and neither is small. Missouri lets a tenant recover twice the amount wrongfully withheld. Kansas lets a tenant recover the portion of the deposit due plus damages equal to one and a half times the amount wrongfully withheld. In both states the exposure is a multiple of the money you were trying to keep, which is why a deduction you cannot document is usually not worth taking.
Which state's law applies to a Kansas City rental property?
The law of the state the property is physically in. Kansas City is one housing market spread across the Missouri–Kansas line, so a manager with units in Raytown and units in Overland Park is operating under two separate deposit statutes with different caps, different clocks, and different penalties — regardless of where the office or the tenant is.
Does Missouri require a move-out inspection with the tenant present?
Missouri gives the tenant the right to be present at the inspection at the time and date the landlord schedules. In practice that turns into a scheduling problem — two calendars, one unit, and a thirty-day clock already running. A walk the tenant films themselves solves the same underlying issue, since the point of the right is that the tenant sees the condition the deductions are based on.
Do I need a license to manage rental property in Kansas City?
Managing property for someone else generally requires a real estate license in both Missouri and Kansas, while managing property you own generally does not. Kansas City, Missouri also runs a rental registration and inspection program, and several suburbs on both sides have their own registration or occupancy inspection requirements. Requirements change, so confirm with the city your unit sits in and with the relevant state real estate commission.
