Roommate Clause
in Your Lease
What it actually means, what Missouri law says, what's specific to Kansas City - and exactly what to do. In plain English.
Quick Summary - What You Need to Know
- No section in our record of Missouri Revised Statutes chapters 441 and 535 sets a number of days for telling a landlord that a new roommate has moved in. Any notice period is a term to look for in the lease.
- Mo. Rev. Stat. § 441.630(5) says an occupant "Shall not under any circumstances take in additional occupants" without the owner's knowledge and consent. It sits among the housing code receivership sections, §§ 441.500 to 441.643, and carries no clock.
- § 441.005(6) defines a tenant for chapters 441, 534 and 535 as "a person who occupies the premises with the landlord's consent."
- § 441.060.2 presumes an occupancy limit of two persons per bedroom reasonable, and that limit does not apply to children born to the tenants during the lease.
- Kansas City's zoning code counts a group of not more than five unrelated persons as one household under § 88-810-700, and its lodging and board standard in § 88-305-12 says "in no case shall more than five unrelated individuals reside within the dwelling."
Understanding the Roommate Clause
A roommate clause decides who may live in the unit, what has to happen before someone joins, and how soon the landlord must hear about it. On that last question, no section in our record of Missouri's chapters 441 and 535 sets a number of days, which leaves your lease as the document that answers it.
Missouri does bring consent into the picture. Mo. Rev. Stat. § 441.630(5) says an occupant shall not take in additional occupants "without the owner's knowledge and consent", and § 441.060.2 presumes two persons per bedroom a reasonable limit. Neither attaches a deadline.
Kansas City answers a different question, about the household. Its zoning code counts a group of not more than five unrelated persons living as one housekeeping unit as a household, and its property maintenance code sets floor space per occupant.

What renters assume
That Missouri gives a Kansas City renter a set number of days after a partner or friend moves in before the landlord must be told, and that any number of unrelated adults may share a home once the lease allows it.
What is actually true
No section in our record of chapters 441 and 535 attaches a day count to adding an occupant; § 441.630(5) speaks of the owner's knowledge and consent. Kansas City's lodging and board standard, § 88-305-12, adds that "in no case shall more than five unrelated individuals reside within the dwelling."
The bars in the comparison on this page measure the deadline for telling a landlord about a new roommate. Two of the 23 rows carry a figure: New York City at 30 days and Seattle at 30 days under a Seattle rule. The other 21 rows carry none.
Twelve of those read no statute: Austin, Los Angeles, Miami, Chicago, Denver, Phoenix, Atlanta, Nashville, Philadelphia, Portland, Boston and Las Vegas. Charlotte, Minneapolis and Milwaukee read no set deadline.
Baltimore reads no set deadline; zoning family limit, Detroit no statute; zoning family limit, Washington, DC lease controls consent, Columbus no statute; lease controls, and Newark no statute; city occupancy caps.
Kansas City's row reads no set deadline; zoning household limit. The definition in § 88-810-700 describes who makes up one household, and our record of it carries no notice period.
Plain English Version
Three separate questions sit under a roommate clause in Kansas City. Whether someone may move in, and how fast you must say so, starts with your lease; no Missouri section in our record sets a deadline for it, though one housing code section speaks of the owner's knowledge and consent.
Missouri presumes two people per bedroom a reasonable limit. And Kansas City's codes describe one household, which can be a group of up to five unrelated people, and set minimum floor space for each person who lives there.
Roommate Clause Example - What the Wording Looks Like in Kansas City, MO
The sample clause below is real lease language - a court quoted it word for word, and then ruled on it. What the judge decided is at the bottom of this block.
Find the equivalent paragraph in your own lease and read the two side by side. The wording will differ; the moving parts rarely do.
REIMBURSEMENT. You must promptly reimburse us for loss, damage, or cost of repairs or service caused anywhere in the apartment community by your or any guest's or occupant's improper use or negligence. […]
Quoted from the published opinion in Churchill Forge, Inc. v. Brown, 61 S.W.3d 368 (Tex. 2001). Judicial opinions are not subject to copyright; the lease language is reproduced in limited part for commentary under 17 U.S.C. § 107.
“You must promptly reimburse”
You is the person the landlord agreed to, and in Missouri that agreement is part of what tenant means. § 441.005(6) defines a tenant for chapters 441, 534 and 535 as “a person who occupies the premises with the landlord's consent.” This sentence then routes the household's damage bill to the person who signed.
“the apartment community”
The lease thinks in buildings. Kansas City's zoning code thinks in households, and it counts them. § 88-810-700 includes in a household “A group of not more than five persons, excluding servants, who need not be related by blood or marriage”, living as a separate nonprofit housekeeping unit with one kitchen. § 88-810-540 makes a dwelling unit the living quarters of a single household.
“by your or any guest's”
A guest and an added occupant are different words, and Missouri's consent rule uses the second. § 441.630(5) speaks of taking in “additional occupants”. Our Missouri record does not mark where a visit ends and an occupancy begins. Read the lease's own guest terms for that line.
“occupant's improper use or negligence”
Kansas City puts code duties on the occupant directly, whatever the lease says. § 56-62 says “every adult occupant of a dwelling shall be responsible for complying with the requirements of this code, even though a similar responsibility is also imposed upon the owner.” The section's subject is every adult occupant, not the leaseholder by name, while this sentence bills the leaseholder for an occupant's carelessness.
The co-signer's defence failed. JoAnn Brown signed an apartment lease as a cotenant with her adult son. He was alleged to have started a fire that damaged the complex, the landlord sued only her, and she argued she could not be charged for damage she had not caused. The Texas Supreme Court disagreed, reversed the summary judgment she had won and held this sentence enforceable against a cotenant who was not herself negligent. The route ran through two sections. Tex. Prop. Code § 92.052(b) gives a landlord no duty to repair damage caused by the tenant, an occupant or a guest, so § 92.006(e) had no repair duty to stop the parties contracting over; and the fair-notice doctrine did not apply, because the sentence does not shift the landlord's own negligence onto the tenant. The court added that neither statute, common law nor the Restatement bars “requiring a tenant to reimburse the landlord for damages negligently caused by the tenant or one occupying the premises with the tenant's consent.” A dissent would have held the sentence unenforceable outright because it was not underlined or conspicuous, as § 92.006(e)(4) requires. This is 2001 Texas law, decided on the Texas Property Code - state-specific, and not a national rule.
One court, one lease, one state. That answer is not automatically yours, and your lease may be worded to land differently. Use this to know what to look for and what to ask - your state's tenant hotline or a local tenant attorney can answer it for your document.
Missouri Law on Roommate Clause
- The state rule is a consent requirement without a timetable, and it sits in a specific part of the chapter. Mo. Rev. Stat. § 441.630 says that "Every occupant of a dwelling unit under the provisions of sections 441.500 to 441.643" must exercise reasonable care, and in subdivision (5) that the occupant "Shall not under any circumstances take in additional occupants, sublease, rent or turn over said premises to any persons without the owner's knowledge and consent." Those sections govern court receiverships to abate housing code nuisances, and § 441.560 makes it a defense in that proceeding that "the occupants are in violation of section 441.630." Separately, § 441.005(6) defines a tenant for chapters 441, 534 and 535 as "a person who occupies the premises with the landlord's consent."
- Missouri presumes two people per bedroom is a reasonable cap. Mo. Rev. Stat. § 441.060.2 provides that "An occupancy limitation of two persons per bedroom residing in a dwelling unit shall be presumed reasonable for this state. The two-person limitation shall not apply to a child or children born to the tenants during the course of the lease." The section creates a presumption about a limit; it does not set a notice period for adding someone.
- Kansas City zoning caps unrelated adults at five. Kansas City Zoning and Development Code § 88-810-700 defines a household as an individual, persons "related by blood, marriage, or adoption", "A group of not more than five persons, excluding servants, who need not be related by blood or marriage, living together and subsisting in common as a separate nonprofit housekeeping unit which provides one kitchen", or a group of eight or fewer unrelated disabled persons with up to two houseparents. Section 88-305-12 allows lodging or board for "not more than one individual or two individuals who are related to each other by blood or marriage" who "must live in common with the household", and adds that "in no case shall more than five unrelated individuals reside within the dwelling."
- Kansas City also sets floor space per person. Kansas City Code of Ordinances § 56-212 requires every dwelling unit to contain "a minimum gross floor area of not less than 120 square feet for the first occupant, and 100 square feet for each additional occupant", and § 56-213 requires a sleeping room for one occupant to have "at least 70 square feet" and one for more than one occupant "at least 50 square feet of floor area for each additional occupant thereof." Under § 56-62, "every adult occupant of a dwelling shall be responsible for complying with the requirements of this code, even though a similar responsibility is also imposed upon the owner."

Start with what our Missouri record leaves open. No section in our record of chapters 441 and 535 sets a number of days for telling a landlord that a new roommate has moved in, and any notice period for adding one is a term to look for in the lease.
What Missouri does write is a consent rule with no clock. Mo. Rev. Stat. § 441.630 lists the duties of "Every occupant of a dwelling unit under the provisions of sections 441.500 to 441.643", starting with reasonable care.
Subdivision (5) says the occupant "Shall not under any circumstances take in additional occupants, sublease, rent or turn over said premises to any persons without the owner's knowledge and consent."
Where that rule sits matters. §§ 441.500 to 441.643 are the sections under which a county, municipality, local housing corporation or neighborhood association may seek a receiver to abate housing code nuisances. § 441.560 makes it a defense in that proceeding that "the occupants are in violation of section 441.630."
Whether subdivision (5) reaches tenancies outside that process is a question our record does not settle, so read it where it stands. Its test is the owner's knowledge and consent, and no day count sits beside it.
Consent also runs through the chapter's definitions. § 441.005(6) defines a tenant for chapters 441, 534 and 535 as "a person who occupies the premises with the landlord's consent." The landlord's agreement is part of what the word tenant means in those chapters.
Missouri also speaks to numbers. § 441.060.2 provides that "An occupancy limitation of two persons per bedroom residing in a dwelling unit shall be presumed reasonable for this state." The two-person limit "shall not apply to a child or children born to the tenants during the course of the lease."
That section creates a presumption about a limit, and it sets no notice period for adding someone. Kansas City's codes, below, measure the same household in persons and in square feet.

Missouri Tenant Protections
Start with the lease. No section in our record of Missouri Revised Statutes chapters 441 and 535 sets a number of days for telling a landlord about a new roommate, which leaves the occupancy paragraph in your lease as the document that answers it.
Next is consent. Mo. Rev. Stat. § 441.630(5), among the housing code receivership sections §§ 441.500 to 441.643, says an occupant shall not take in additional occupants, sublease, rent or turn over the premises without the owner's knowledge and consent.
Section 441.560 makes an occupant's violation of § 441.630 a defense in that proceeding. Under § 441.005(6), a tenant for chapters 441, 534 and 535 is a person who occupies the premises with the landlord's consent.
Then there is a number. Section 441.060.2 presumes an occupancy limit of two persons per bedroom reasonable, and the limit does not apply to children born to the tenants during the lease.
In Kansas City, Zoning and Development Code § 88-810-700 counts a group of not more than five unrelated persons living together as a separate nonprofit housekeeping unit with one kitchen as a household. Section 88-305-12 allows lodging or board for one individual or two related individuals, with no more than five unrelated individuals in the dwelling.
Section 56-212 requires 120 square feet of floor area for the first occupant and 100 for each additional one, and § 56-213 sets 70 square feet for a one-person sleeping room and 50 more for each additional sleeper. Section 56-62 makes every adult occupant responsible for complying with the code. Read the current text of each section before relying on it.
What's Specific to Kansas City
Figures are the state rule, or the stronger city ordinance where one exists. Verify the current law for your own situation before relying on it.
Kansas City's zoning code starts from the household. § 88-810-540 defines a dwelling unit as independent living quarters for a single household, and § 88-810-700 says who counts. A household includes an individual, persons related by blood, marriage or adoption, and "A group of not more than five persons, excluding servants, who need not be related by blood or marriage", living together as a separate nonprofit housekeeping unit with one kitchen.
A fourth form covers a group of eight or fewer unrelated disabled persons, with up to two houseparents. These are land-use definitions, and they describe a household rather than a lease.
Renting out a room has a standard of its own. Under § 88-305-12, lodging and board is limited to "not more than one individual or two individuals who are related to each other by blood or marriage", who "must live in common with the household".
The section adds that "in no case shall more than five unrelated individuals reside within the dwelling."
The property maintenance code measures space. § 56-212 requires "a minimum gross floor area of not less than 120 square feet for the first occupant, and 100 square feet for each additional occupant". Under § 56-213, a sleeping room for one needs at least 70 square feet, and a shared one at least 50 square feet for each additional occupant.
Those duties are not the owner's alone. § 56-62 says "every adult occupant of a dwelling shall be responsible for complying with the requirements of this code, even though a similar responsibility is also imposed upon the owner." The section's subject is every adult occupant, not the leaseholder by name.
On the notice question itself, our record of the Kansas City Code of Ordinances and the Zoning and Development Code finds no section setting a deadline to tell a landlord about an added occupant. A Municode text search for roommate across both codes returned no results.
Municode marks the Code of Ordinances as codified through Ordinance No. 260342, enacted April 16, 2026, and the zoning code through Ordinance No. 260478, enacted May 21, 2026. Read § 88-810-700 and § 56-212 as they stand on the day you need them.
Missouri's § 441.043, in the version effective August 28, 2025, lists the subjects a city may not regulate between landlord and tenant, and an occupancy limit is not among them. We describe the Kansas City sections as enacted and take no position on how § 441.043 applies to any of them.
No section in our record of Missouri's chapters 441 and 535 sets a deadline for this notice, which leaves the lease as the place one would be written.
§ 441.630(5) speaks of the owner's "knowledge and consent", and § 441.005(6) defines a tenant as a person who occupies "with the landlord's consent". A dated written yes records both.
Kansas City's § 88-810-700 counts a group of not more than five unrelated persons as one household, and § 88-305-12 says no more than five unrelated individuals may reside within the dwelling.
§ 441.060.2 presumes two persons per bedroom a reasonable limit, and Kansas City's § 56-213 asks for 50 square feet for each additional sleeper in a shared room.

Red Flags to Watch Out For
-
A day count said to be Missouri law
If you are told Missouri fixes a deadline for reporting a roommate, ask for the section. No section in our record of chapters 441 and 535 sets one.
-
A sixth unrelated adult moving in
§ 88-305-12 says "in no case shall more than five unrelated individuals reside within the dwelling." A landlord's yes does not change what the zoning code counts.
-
A third sleeper in one bedroom
§ 441.060.2 presumes a limit of two persons per bedroom reasonable, so a lease cap at that number has the presumption behind it. Children born to the tenants during the lease sit outside the limit.
-
A roommate moved in on a nod
§ 441.630(5) speaks of the owner's knowledge and consent. A spoken yes is hard to show later, so get the consent in writing with the person's name and the date.
-
A shared room under the floor minimum
§ 56-213 asks for at least 70 square feet for one sleeper and 50 square feet more for each additional one, and § 56-62 makes every adult occupant responsible for meeting the code.
Your Rights as a Kansas City Tenant
-
Two per bedroom is presumed reasonable
§ 441.060.2 presumes an occupancy limit of two persons per bedroom reasonable, and the limit "shall not apply to a child or children born to the tenants during the course of the lease."
-
A tenant is defined by consent
§ 441.005(6) defines a tenant for chapters 441, 534 and 535 as "a person who occupies the premises with the landlord's consent."
-
A household of up to five
Kansas City's § 88-810-700 counts a group of not more than five persons, excluding servants, who need not be related, living as a separate nonprofit housekeeping unit with one kitchen, as one household.
-
Floor space measured per person
§ 56-212 requires at least 120 square feet of floor area for the first occupant and 100 square feet for each additional occupant, calculated on the habitable rooms.
What To Do - Step by Step
Find what the lease says about added occupants
Look for who may live there, whether consent is needed and any notice period. No section in our record of chapters 441 and 535 sets a deadline, which leaves those terms as the text that answers it.
Count the household against the zoning code
Kansas City's § 88-810-700 counts a group of not more than five unrelated persons as one household. Check where the new person falls before anyone moves in.
Count sleepers per bedroom
§ 441.060.2 presumes two persons per bedroom reasonable. § 56-213 asks for 70 square feet for one sleeper and 50 square feet more for each additional one.
Ask for consent in writing
Give the person's full name and planned move-in date. § 441.630(5) speaks of the owner's knowledge and consent, so keep the landlord's written reply with your lease.
Measure the whole unit
§ 56-212 requires 120 square feet of floor area for the first occupant and 100 square feet for each additional one, counted across the habitable rooms.
Check the current text before relying on it
Read § 441.630, § 441.060 and § 441.005 on revisor.mo.gov, and check § 88-810-700 and § 56-212 against Kansas City's current codes.
