Roommate Clause
in Your Lease
What it actually means, what Ohio law says, what's specific to Columbus - and exactly what to do. In plain English.
Quick Summary - What You Need to Know
- Ohio Rev. Code § 5321.05(A) opens "A tenant who is a party to a rental agreement shall do all of the following" and runs nine numbered duties, all about the condition and use of the premises. None of them is a duty to report an added occupant.
- The nearest of the nine is § 5321.05(A)(8), a duty to "Conduct himself and require other persons on the premises with his consent to conduct themselves in a manner that will not disturb his neighbors' peaceful enjoyment of the premises." That governs how a roommate behaves, not when the landlord hears about one.
- The chapter does write day counts where it means to. § 5321.17(A) lets either party "terminate or fail to renew a week-to-week tenancy by notice given the other at least seven days prior to the termination date specified in the notice", and § 5321.17(B) sets the month-to-month figure at "at least thirty days prior to the periodic rental date".
- Columbus City Code § 4541.01 provides that "Every room occupied for sleeping purposes by one occupant shall contain at least seventy (70) square feet of floor space, and every room occupied for sleeping purposes by more than one person shall contain at least fifty (50) square feet of floor space for each occupant thereof."
- One section does restrict who may be let in, and it is a prohibition rather than a clock. Ohio Rev. Code § 5321.051(A)(1) provides that "No tenant of any residential premises located within one thousand feet of any school premises, preschool or child care center premises, children's crisis care facility premises, or residential infant care center premises shall allow any person to occupy those residential premises" where that person is listed on the state registry of sex offenders and child-victim offenders for a stated conviction.
Understanding the Roommate Clause
A roommate clause settles three things: whose names may appear on the occupancy line, what has to happen before somebody joins them, and how fast the office has to hear about it. In Columbus the first two of those belong to your lease and the third has no state answer that our reading found.
The place a reporting deadline would sit in Ohio law is the tenant duty list, Ohio Rev. Code § 5321.05, and it is not there. § 5321.06 then lets the parties write any term not inconsistent with or prohibited by the chapter or another rule of law, which is how the roommate paragraph ends up carrying the day count instead of a statute.
Columbus does supply a limit, and it answers a different question from the one the lease answers. Columbus City Code § 4541.01 and § 4541.015 measure how many people a unit may hold in square feet of floor space rather than in heads, and a landlord saying yes does nothing to that arithmetic.
What renters assume
That Ohio gives a renter a grace period, some number of days after a partner or a friend moves in, within which telling the landlord keeps everything above board.
What is actually true
No section our Ohio record read in Chapter 5321 attaches a day count to adding an occupant. The chapter's day counts are elsewhere and do a different job: § 5321.17(A) fixes seven days for ending a week-to-week tenancy and § 5321.17(B) thirty days for a month-to-month one. Those are notice periods for ending a tenancy, not windows for reporting a roommate, and borrowing one to justify a delay is borrowing from the wrong section.
The metric behind these bars is the deadline to notify a landlord that a new roommate has moved in. Twenty-two rows sit on this chart and two of them carry a day count: New York City at 30 days to name an added occupant, and Seattle at 30 days under a city-only rule. Twelve read no statute: Austin, Los Angeles, Miami, Chicago, Denver, Phoenix, Atlanta, Nashville, Philadelphia, Portland, Boston and Las Vegas. Washington reads lease controls consent. Columbus reads no statute, lease controls. Newark reads no statute, city occupancy caps. Detroit reads no statute, zoning family limit. Charlotte, Minneapolis and Milwaukee read no set deadline. Baltimore reads no set deadline, zoning family limit.
Columbus and Washington sit apart from the twelve for the same reason, which is that their labels name the document that fills the gap rather than stopping at the absence. On the Ohio side that document is identified by a section: Ohio Rev. Code § 5321.06 lets a landlord and a tenant include any term not inconsistent with or prohibited by Chapter 5321 or another rule of law, so the reporting term is a lawful term of the agreement and its deadline is whatever the agreement says. A renter in Columbus reading this chart should not conclude that nothing governs the question. The right conclusion is that the governing text is in their own file rather than in the Revised Code, and that it was negotiable on the day it was signed.
One number on the Ohio side could be mistaken for the one this chart counts. § 5321.17(B) requires at least thirty days' notice before the periodic rental date to end a month-to-month tenancy. That thirty runs on ending an arrangement, not on adding a person to one, and it belongs to whichever party is giving the notice.
Plain English Version
Three separate questions, and they do not answer each other. Whether the person may move in, and how fast you have to say so, come from your lease, because the Ohio sections we read leave that term to the parties. How many people the rooms can legally hold comes from the Columbus housing code, in square feet. And one state section bars letting a particular person occupy the premises at all, regardless of what the lease permits. A landlord's approval settles the first question and leaves the other two untouched.
Roommate Clause Example - What the Wording Looks Like in Columbus, OH
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.
“REIMBURSEMENT. You must”
The duty under this heading belongs to whoever signed, and Ohio's own duty list opens on that same person. § 5321.05(A) begins “A tenant who is a party to a rental agreement shall do all of the following” and runs nine numbered duties, all of them about the condition and use of the premises. Paying for what somebody else broke is not among the nine; it is a term this paragraph adds, and § 5321.06 leaves the parties free to write their own.
“us for loss, damage”
The closest the duty list comes to other people is a behaviour rule, not a money rule. § 5321.05(A)(8) requires a tenant to “Conduct himself and require other persons on the premises with his consent to conduct themselves in a manner that will not disturb his neighbors' peaceful enjoyment of the premises.” A roommate keeping the neighbours awake is inside that duty. Loss and damage is the currency this sentence deals in, and no section our Ohio record read puts a ceiling on the figure.
“anywhere in the apartment community by”
This sentence draws its boundary by place; Columbus draws one too, in square feet. Columbus City Code § 4541.01 requires a sleeping room to hold at least seventy square feet of floor space for one occupant, and at least fifty square feet for each occupant where more than one person sleeps in it. § 4541.015 adds a minimum occupancy area table: a living room needs 120 square feet for 3 to 5 occupants and 150 for 6 or more, a dining room 80 and 100, a kitchen 50 for 1 to 2 occupants, 50 for 3 to 5 and 60 for 6 or more. A child under one year of age is not counted as an additional occupant.
“guest's or occupant's improper”
Occupant is the word carrying the risk: someone living there who signed nothing. Columbus puts a duty on that person directly - § 4551.02(j) requires that “Every occupant shall limit occupancy of that part of the premises which the occupant occupies or controls to the maximum permitted by this Code.” The one restriction our Ohio record found on who may be let in is a prohibition, not a clock: § 5321.051(A)(1) bars a tenant of premises within one thousand feet of school, preschool, child care, children's crisis care or residential infant care premises from letting a person on the state registry of sex offenders and child-victim offenders, for a stated conviction, occupy them.
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.
Ohio Law on Roommate Clause
- The tenant duty list is where a notice deadline would sit, and it is not there. Ohio Rev. Code § 5321.05(A) opens "A tenant who is a party to a rental agreement shall do all of the following" and then runs nine numbered duties, all of them about the condition and use of the premises. The closest any of them comes to other occupants is § 5321.05(A)(8), a duty to "Conduct himself and require other persons on the premises with his consent to conduct themselves in a manner that will not disturb his neighbors' peaceful enjoyment of the premises." That governs how a guest or roommate behaves, not when the landlord must be told one exists.
- The chapter does fix notice periods, which is what makes its silence here legible. Ohio Rev. Code § 5321.17(A) allows either party to "terminate or fail to renew a week-to-week tenancy by notice given the other at least seven days prior to the termination date specified in the notice", and § 5321.17(B) sets the month-to-month figure "at least thirty days prior to the periodic rental date". Those are deadlines the legislature wrote for ending a tenancy. No section we read attaches any comparable day count to adding an occupant, and § 5321.06 leaves that term to the rental agreement.
- Columbus caps occupancy by floor area rather than by a headcount. Columbus City Code § 4541.01 provides that "Every room occupied for sleeping purposes by one occupant shall contain at least seventy (70) square feet of floor space, and every room occupied for sleeping purposes by more than one person shall contain at least fifty (50) square feet of floor space for each occupant thereof." Section 4541.015 adds a Minimum Occupancy Area Requirements Table: a living room needs 120 square feet for 3 to 5 occupants and 150 for 6 or more, a dining room 80 and 100, and a kitchen 50 square feet for 1 to 2 occupants, 50 for 3 to 5 and 60 for 6 or more. The section adds that "a child under one year of age shall not be counted as an additional occupant."
- One section of the chapter does restrict who may be let in, and it is a prohibition rather than a notice clock. Ohio Rev. Code § 5321.051(A)(1) provides that "No tenant of any residential premises located within one thousand feet of any school premises, preschool or child care center premises, children's crisis care facility premises, or residential infant care center premises shall allow any person to occupy those residential premises" where that person is listed on the state registry of sex offenders and child-victim offenders for a stated conviction. On the Columbus side the duty runs to the occupant: § 4551.02(j) requires that "Every occupant shall limit occupancy of that part of the premises which the occupant occupies or controls to the maximum permitted by this Code."

Start where a reporting deadline would live if Ohio had written one. Ohio Rev. Code § 5321.05(A) opens "A tenant who is a party to a rental agreement shall do all of the following" and then lists nine numbered duties. They are about the condition and the use of the premises: the duties a renter owes to the property. None of them is a duty to notify a landlord that an occupant has been added, and none of them carries a day count.
The closest any of the nine comes to other people in the unit is § 5321.05(A)(8), a duty to "Conduct himself and require other persons on the premises with his consent to conduct themselves in a manner that will not disturb his neighbors' peaceful enjoyment of the premises." Read that carefully, because it does confirm that other people may be on the premises with the tenant's consent. What it regulates is their behaviour. It says nothing about when their arrival must be reported.
What makes that silence legible rather than merely absent is that the same chapter writes clocks freely elsewhere. § 5321.17(A) allows either party to "terminate or fail to renew a week-to-week tenancy by notice given the other at least seven days prior to the termination date specified in the notice", and § 5321.17(B) sets the month-to-month figure at "at least thirty days prior to the periodic rental date". The legislature wrote day counts for ending a tenancy. No section we read attaches one to adding an occupant.
Which leaves § 5321.06 holding the question: "A landlord and a tenant may include in a rental agreement any terms and conditions, including any term relating to rent, the duration of an agreement, and any other provisions governing the rights and obligations of the parties that are not inconsistent with or prohibited by Chapter 5321. of the Revised Code or any other rule of law." A clause requiring written approval before anyone moves in, or notice within a stated number of days, is such a term. It binds because you agreed to it, and the number in it is not measured against any state figure.
One section of the chapter does restrict who may be let in, and it is worth reading precisely because it is a prohibition rather than a procedure. § 5321.051(A)(1) provides that "No tenant of any residential premises located within one thousand feet of any school premises, preschool or child care center premises, children's crisis care facility premises, or residential infant care center premises shall allow any person to occupy those residential premises" where that person is listed on the state registry of sex offenders and child-victim offenders for a stated conviction. That is a bar on occupancy in defined circumstances, not a notice clock, and no lease term makes it go away.
The scope of the reading behind all of this, because a negative is worth exactly what its scope is worth. We read the bodies of § 5321.01, § 5321.02, § 5321.04, § 5321.05, § 5321.06, § 5321.07, § 5321.13, § 5321.15, § 5321.16, § 5321.19 and § 5321.20 in full, and the opening text only of § 5321.03, § 5321.051, § 5321.08, § 5321.09, § 5321.10, § 5321.11, § 5321.12, § 5321.14, § 5321.17 and § 5321.18. The chapter runs from § 5321.01 to § 5321.20, there is no § 5321.21, and § 5321.20 is a legislative findings section on rent control and rent stabilization rather than an operative rule. A duty tucked deeper inside one of the ten sections whose opening text alone was read has not been ruled out.
Those texts were read on a commercial republisher of the Revised Code, each page carrying the line "Current as of January 01, 2026". Read § 5321.05, § 5321.06 and § 5321.17 as they stand today before you rely on any of this in a dispute.
Ohio Tenant Protections
The protection that matters here is a negotiating one, and it comes from where the rule sits rather than from what it says.
Because no section our Ohio record read in Chapter 5321 imposes a deadline for reporting an added occupant, and because Ohio Rev. Code 5321.06 provides that a landlord and a tenant may include in a rental agreement any terms and conditions, including any term relating to rent, the duration of an agreement, and any other provisions governing the rights and obligations of the parties that are not inconsistent with or prohibited by Chapter 5321 of the Revised Code or any other rule of law, the roommate paragraph is a term open to negotiation before it is signed.
A clause promising a written decision within a named number of days, or promising that approval will not be unreasonably withheld, binds as a contract term even where our reading finds no statute demanding one. Two state provisions sit alongside that.
Ohio Rev. Code 5321.05(A) lists nine tenant duties, and 5321.05(A)(8) requires a tenant to conduct himself and require other persons on the premises with his consent to conduct themselves in a manner that will not disturb his neighbors' peaceful enjoyment of the premises, which confirms that other people may be on the premises with the tenant's consent while regulating only their behaviour.
And Ohio Rev. Code 5321.051(A)(1) provides that no tenant of residential premises located within one thousand feet of any school premises, preschool or child care center premises, children's crisis care facility premises, or residential infant care center premises shall allow any person to occupy those premises where that person is listed on the state registry of sex offenders and child-victim offenders for a stated conviction; that is a prohibition a lease cannot lift.
On the Columbus side, Columbus City Code 4541.01 requires every room occupied for sleeping purposes by one occupant to contain at least seventy square feet of floor space and every room occupied for sleeping purposes by more than one person to contain at least fifty square feet of floor space for each occupant, 4541.015 adds a Minimum Occupancy Area Requirements Table, and 4551.02(j) requires every occupant to limit occupancy of that part of the premises which the occupant occupies or controls to the maximum permitted by the Code. Ohio Rev. Code 5321.19(A) bars a political subdivision from regulating what Chapter 5321 regulates, and says so except as provided in division (B); Ohio Rev. Code 5321.19(B)(1) provides that the chapter does not preempt a housing, building, health or safety code of a political subdivision, and Chapter 4541 and Chapter 4551 both sit in Columbus City Codes Title 45, the Housing Code. The Columbus sections are described here as enacted and this page does not predict how those divisions would apply to them.
Confirm the current text of each before relying on it.
What's Specific to Columbus
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.
Columbus answers a question the lease does not, and it answers it with a tape measure. Columbus City Code § 4541.01 provides that "Every room occupied for sleeping purposes by one occupant shall contain at least seventy (70) square feet of floor space, and every room occupied for sleeping purposes by more than one person shall contain at least fifty (50) square feet of floor space for each occupant thereof." So the bedroom, not the building and not the headcount, is where the limit is applied.
§ 4541.015 extends that with a Minimum Occupancy Area Requirements Table covering the shared rooms. A living room needs 120 square feet for 3 to 5 occupants and 150 for 6 or more; a dining room 80 and 100; a kitchen 50 square feet for 1 to 2 occupants, 50 for 3 to 5 and 60 for 6 or more. The section adds that "a child under one year of age shall not be counted as an additional occupant."
The duty to stay inside those figures runs to the person living there. Columbus City Code § 4551.02(j) requires that "Every occupant shall limit occupancy of that part of the premises which the occupant occupies or controls to the maximum permitted by this Code." That is why a landlord's approval of a fourth person is not the end of the enquiry: the approval answers the lease, and the square footage answers the code.
How far the Columbus reading went. We read Chapter 4541 and Chapter 4551 in full on Municode. The page states that the code is "Codified through Ordinance No. 0923-2026, enacted April 20, 2026. (Supp. No. 85, 6/26)" and warns that it "may not reflect the most current legislation adopted by the Municipality". A later ordinance would not be in the text we read, so check the current edition before you measure anything against these numbers.
One structural note about every Columbus provision above. Ohio Rev. Code § 5321.19(A) bars a political subdivision from regulating what Chapter 5321 regulates, and it does so "Except as provided in division (B) of this section". Division (B)(1) is set out in the code as "Housing, building, health, or safety code, or any ordinance as described in division (A)(9) of section 5321.04 of the Revised Code, of any political subdivision". The square-footage sections above are in Chapter 4541 and Chapter 4551, both of which Columbus placed in Title 45, the Housing Code. These sections are described here as enacted, which is what our record supports; this page does not predict how the two divisions would apply to them, in either direction. If a Columbus provision is what your dispute turns on, that is a question for advice rather than for a guide.
The sections our Ohio record read supply neither, so any timeline you can enforce is one the agreement itself sets out. Ohio Rev. Code § 5321.06 is what makes such a term binding once it is in the document.
That single line is leverage a statute is not giving you here. Ask for it before signature, since the term is one the parties write.
Columbus City Code § 4541.01 requires at least seventy square feet for one occupant of a sleeping room and at least fifty square feet for each occupant where more than one person sleeps there. Measure before anyone commits.
No section our Ohio record read supplies a night count, so the number in the lease is the one that governs. Find it and read it rather than assuming a standard.

Red Flags to Watch Out For
-
Approval required with no reply window
A consent requirement with no date attached to the landlord's answer. Nothing in the sections our record read fills that in, which means a request has no point at which it becomes overdue unless the agreement gives it one.
-
A reporting deadline nobody can find
If a manager cites a state deadline for telling them about a new occupant, ask which section. No section our Ohio record read in Chapter 5321 attaches a day count to adding one.
-
The thirty days in § 5321.17(B) quoted at you
§ 5321.17(B) requires notice "at least thirty days prior to the periodic rental date" to end a month-to-month tenancy. It is a termination notice period, and it is not a window for reporting a roommate.
-
A bedroom that will not measure up
Columbus City Code § 4541.01 sets seventy square feet for one sleeping occupant and fifty per occupant where more than one sleeps in the room, and § 4551.02(j) puts the duty to stay within the maximum on the occupant.
-
A blank occupancy line on the agreement
The roommate term carries the day count here, so an unfilled or missing occupancy paragraph leaves the question open at exactly the moment it is asked. Get names and the process written down before signature.
Your Rights as a Columbus Tenant
-
Guests are contemplated by the duty list
Ohio Rev. Code § 5321.05(A)(8) requires a tenant to "Conduct himself and require other persons on the premises with his consent to conduct themselves" so as not to disturb neighbours. It regulates behaviour, and it assumes other people may be there with your consent.
-
The term is written, so it can be negotiated
§ 5321.06 lets a landlord and a tenant include any terms not inconsistent with or prohibited by Chapter 5321 or another rule of law. A better roommate clause is asked for before signature, not argued for after.
-
Floor space is measured, not asserted
Columbus City Code § 4541.01 and § 4541.015 state the minimums in square feet, and § 4541.015 provides that "a child under one year of age shall not be counted as an additional occupant." Ohio Rev. Code § 5321.19(A) restricts local measures on ground Chapter 5321 covers, and § 5321.19(B)(1) excepts a housing, building, health or safety code of a political subdivision; Chapter 4541 is in Title 45, the Columbus Housing Code. This page does not predict how those divisions would apply to these sections.
-
Ending a tenancy has its own notice periods
§ 5321.17(A) sets at least seven days for a week-to-week tenancy and § 5321.17(B) at least thirty days before the periodic rental date for a month-to-month one, running either way between the parties.
What To Do - Step by Step
Read the roommate paragraph word for word
Find whether approval is required, what it costs, what counts as a guest, and whether any deadline is stated. With no state day count in the sections our record read, that paragraph is the rulebook.
Measure the room the new person will sleep in
Columbus City Code § 4541.01 requires at least seventy square feet for a single sleeping occupant and fifty square feet per occupant where more than one sleeps there. Settle that before anyone gives notice on their current place.
Ask in writing, with the name and the date
Send the request by email with the person's full name and the intended move-in date. Where no statute supplies a timeline, the thread you create is the timeline.
Set your own follow-up date
Nothing our record read obliges a reply by any date. Pick one, say in the original message that you will follow up then, and follow up in the same thread so the sequence stays in one place.
Check the occupancy prohibition before anyone moves in
Ohio Rev. Code § 5321.051(A)(1) bars a tenant of premises within one thousand feet of the named school, preschool, child care, crisis care or infant care premises from allowing occupancy by a person listed on the state registry for a stated conviction. No lease term reaches that.
Verify the current text, then get help if it stalls
Read Ohio Rev. Code § 5321.05, § 5321.06 and § 5321.17 as published today, and check Chapters 4541 and 4551 against the current Columbus edition, since the copy our record read was codified through an April 2026 ordinance and warns that later legislation may not be reflected. If approval is refused or ignored, a Columbus legal aid or tenant advice service is the next call.
