Roommate Clause
in Your Lease
What it actually means, what Maryland law says, what's specific to Baltimore - and exactly what to do. In plain English.
Quick Summary - What You Need to Know
- Our record of Maryland's Real Property Article, a text search of Title 8 in the General Assembly's own text, finds no deadline for telling a landlord that a new roommate has moved in. The roommate paragraph of the lease is the document that answers the notice question.
- Real Property § 8-5A-01(c) defines a "Legal occupant" as "an occupant who resides on the premises with the actual knowledge and permission of the landlord". Knowledge and permission are both in the definition.
- Under § 8-5A-02(a) a tenant may terminate future liability under a residential lease if the tenant or a legal occupant is a victim of abuse, subject to the written notice and other requirements of that subtitle.
- Baltimore's Zoning Code § 1-306(g) counts as a family a group of not more than 4 people who need not be related, living as a single housekeeping unit. § 1-305(u) ties a dwelling unit to no more than 1 family.
- The city's Property Maintenance Code measures space: under § 404.4.1 a bedroom for one person needs at least 70 sq. ft. of floor area, and a shared bedroom at least 50 square feet for each occupant.
Understanding the Roommate Clause
A roommate clause answers who may live in the unit, what must happen before someone joins, and how soon the landlord must hear about it. On the last question, our record of Maryland's Real Property Article finds no deadline, which leaves the roommate paragraph of your lease as the document that answers it.
Maryland does give a roommate the landlord knows about a name. Real Property § 8-5A-01(c) calls a person who "resides on the premises with the actual knowledge and permission of the landlord" a legal occupant. That status matters in the abuse exit in § 8-5A-02(a).
Baltimore answers a different question, about the size of a household. Its Zoning Code counts a group of not more than 4 unrelated people as one family, and its Property Maintenance Code sets a floor area for each person in a bedroom.
Neither definition, as our record quotes it, turns on a landlord's approval.
What renters assume
That Maryland gives a Baltimore renter a set number of days after a partner or a friend moves in before the landlord has to be told.
What is actually true
Our record of Maryland's Real Property Article finds no deadline for that notice. What Maryland writes is a status: under § 8-5A-01(c) a legal occupant resides there "with the actual knowledge and permission of the landlord".
Baltimore's limits, in Zoning Code § 1-306(g), are on the size of the household, not on timing.
The bars in the comparison on this page measure the deadline for telling a landlord about a new roommate. Two of the 20 rows carry a figure: New York City at 30 days and Seattle at 30 days under a Seattle rule. The other 18 rows carry none.
Twelve of those read no statute: Austin, Los Angeles, Miami, Chicago, Denver, Phoenix, Atlanta, Nashville, Philadelphia, Portland, Boston and Las Vegas. Washington, DC reads lease controls consent, Columbus no statute; lease controls, Newark no statute; city occupancy caps, Detroit no statute; zoning family limit, Charlotte no set deadline, and Baltimore no set deadline; zoning family limit.
Baltimore's label pairs a gap with a limit. The gap is the notice period, which our Maryland record does not supply. The limit is Zoning Code § 1-306(g), whose 4 counts unrelated people in one household, not days.
Plain English Version
Our record of Maryland's landlord and tenant law finds no deadline for telling your landlord about a new roommate, which leaves your lease as the document that answers it. A person who lives there with the landlord's knowledge and permission is a legal occupant under Maryland law, and that matters if either of you needs to leave a lease because of abuse.
Baltimore's zoning code treats up to 4 unrelated people as one household. The city's maintenance code also sets a minimum floor area for each person in a bedroom.
Roommate Clause Example - What the Wording Looks Like in Baltimore, MD
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 us”
You means everyone who signed, and in Baltimore signing together has a fair housing side. Article 4, § 3-5(a)(9) lists a refusal “to consider 2 or more applicants' incomes when they seek to buy or rent a dwelling or dwelling unit” among practices unlawful when done because of a protected trait such as marital status or familial status. Applying as a pair is what puts two names in the place of you, and this sentence then speaks to each of them.
“caused anywhere in the apartment community”
The lease measures responsibility across the whole community. Baltimore's Zoning Code measures a household inside one unit. § 1-305(u) says a dwelling unit is used “as living facilities for no more than 1 family”, and § 1-306(g)(3) says a family does not include, in any case, more than 4 unrelated people. The landlord's reach in this sentence is wide; the city's count of who may live in the unit is narrow.
“by your or any guest's”
The lease charges you for a guest's conduct. The zoning definition our record quotes counts family members and roomers, and says nothing of guests. Under § 1-306(g) up to 2 roomers may live with an individual or with people related by blood, marriage, adoption or State-supervised foster care, where they share a common entrance and cooking and bathroom facilities. A group of unrelated housemates is not given that allowance.
“or occupant's improper use or negligence”
Occupant has a statutory meaning in Maryland when the landlord knows about the person. Real Property § 8-5A-01(c) defines a legal occupant as one “who resides on the premises with the actual knowledge and permission of the landlord.” This sentence makes you answer for that person's negligence. § 8-5A-02(a) runs the other way when the occupant is in danger: a tenant may end future liability if the tenant or a legal occupant is a victim of abuse.
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.
Maryland Law on Roommate Clause
- Baltimore's zoning definition caps unrelated housemates at four. Zoning Code § 1-306(g)(1) defines a family as "an individual", "2 or more people related by blood, marriage, adoption, or State-supervised foster care, living together as a single housekeeping unit in a dwelling unit", or "a group of not more than 4 people, who need not be related, living together as a single housekeeping unit in a dwelling unit", together with customary household helpers. Section 1-306(g)(3) says a family does not include, in any case, more than 4 unrelated people or the occupants of a rooming house, a hotel or motel, or a fraternity or sorority house.
- A dwelling unit is tied to that definition. Zoning Code § 1-305(u) says a dwelling unit means 1 or more rooms in a dwelling that "are used as living facilities for no more than 1 family" and contain permanently installed bathroom and kitchen facilities reserved for the occupants of those rooms.
- The Property Maintenance Code limits occupants by floor area. Section 404.4.1 says "Every bedroom occupied by 1 person must contain at least 70 sq. ft." of floor area and every bedroom occupied by more than one person at least 50 square feet for each occupant. Section 404.5 bars occupying a dwelling unit with more occupants than Table 404.5 permits: 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 5 occupants and 60 for 6 or more. Section 404.9 sets a minimum dwelling unit size of 240 square feet of clear floor area.
- Maryland law gives a roommate the landlord knows about one statutory role. Real Property § 8-5A-01(c) defines a "Legal occupant" as "an occupant who resides on the premises with the actual knowledge and permission of the landlord", and § 8-5A-02(a) lets a tenant terminate future liability under a residential lease if the tenant or a legal occupant is a victim of abuse, subject to the written notice and other requirements of that subtitle.
4, § 3-5(j) - statutes change; verify the current text for your situation.
Start with what our Maryland record leaves open. Our record of the Real Property Article, a text search of Title 8 in the General Assembly's own text, finds no deadline for telling a landlord that a new roommate has moved in.
That leaves the roommate paragraph of the lease as the document that answers the notice question.
The contrast in the comparison on this page is New York, whose row carries 30 days. Nothing in our Maryland record supplies an equivalent figure.
What Maryland does write is a status for the person a landlord knows about. Real Property § 8-5A-01(c) says "'Legal occupant' means an occupant who resides on the premises with the actual knowledge and permission of the landlord."
The definition has two parts, and both point at the landlord. Knowledge is one; permission is the other. A roommate the landlord has never heard of is not who those words describe, and neither is one the landlord knows about but has not permitted.
The status does its work in Subtitle 5A. Under § 8-5A-02(a), a tenant may terminate the tenant's future liability under a residential lease if the tenant or a legal occupant is a victim of abuse. That right is subject to the written notice and other requirements of the subtitle.
Read together, the two sections reach a roommate who never signed. Where the person in danger is a legal occupant rather than a tenant, it is the tenant who may end future liability under § 8-5A-02(a).
Whether a roommate is a legal occupant turns on the landlord's actual knowledge and permission.
That gives a written request a second use. The lease may set no deadline, but a request naming the new person, and the landlord's written reply, are a record of both knowledge and permission.
Our Maryland record does not reach how many people may share a unit or a bedroom. Those limits come from Baltimore's codes, set out below.

Maryland Tenant Protections
Our record of Maryland's Real Property Article, a text search of Title 8, finds no deadline for telling a landlord that a new roommate has moved in, which leaves the roommate paragraph of the lease as the document that answers the notice question. Real Property § 8-5A-01(c) defines a legal occupant as an occupant who resides on the premises with the actual knowledge and permission of the landlord.
Under § 8-5A-02(a), a tenant may terminate future liability under a residential lease if the tenant or a legal occupant is a victim of abuse, subject to the written notice and other requirements of that subtitle. In Baltimore, Zoning Code § 1-306(g) counts as a family an individual, 2 or more people related by blood, marriage, adoption or State-supervised foster care, or a group of not more than 4 people who need not be related, living as a single housekeeping unit.
Under § 1-305(u) a dwelling unit is used as living facilities for no more than 1 family. Property Maintenance Code § 404.4.1 requires at least 70 sq. ft. of floor area in a bedroom occupied by 1 person and at least 50 square feet for each occupant of a shared bedroom.
Article 4, § 3-5(a)(9) lists, among practices unlawful when done because of a protected trait such as marital status or familial status, a refusal to consider 2 or more applicants' incomes.
Read the current text of each section before relying on it.
What's Specific to Baltimore
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.
Baltimore's roommate rules are about the household, not the notice. Our record of the Baltimore City Code, read on codes.baltimorecity.gov, finds no Baltimore ordinance setting a deadline to tell a landlord about a new occupant.
A text search of that code returned no results for "roommate" and one for "roomer", Zoning Code § 1-306.
That section is where the household limit sits. Under § 1-306(g)(1), together with customary household helpers, a family means one of these:
- an individual
- 2 or more people related by blood, marriage, adoption, or State-supervised foster care, living together as a single housekeeping unit in a dwelling unit
- "a group of not more than 4 people, who need not be related, living together as a single housekeeping unit in a dwelling unit"
§ 1-306(g)(3) closes the definition. A family "does not include, in any case" more than 4 unrelated people, or the occupants of a rooming house, a hotel or motel, or a fraternity or sorority house.
Roomers have a narrower route. An individual, or a family of related people, may have up to 2 roomers, where they share a common entrance and cooking and bathroom facilities.
The allowance attaches to those two kinds of family, not to a group of unrelated housemates.
The definition feeds the dwelling unit. § 1-305(u) says a dwelling unit means 1 or more rooms that "are used as living facilities for no more than 1 family" and contain permanently installed bathroom and kitchen facilities reserved for their occupants.
The Property Maintenance Code counts space. § 404.4.1 says "Every bedroom occupied by 1 person must contain at least 70 sq. ft." of floor area, and a shared bedroom needs at least 50 square feet for each occupant. § 404.9 sets a minimum dwelling unit of 240 square feet of clear floor area.
§ 404.5 bars more occupants than Table 404.5 permits. 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 for 1 to 5 occupants and 60 for 6 or more.
A rooming house is defined apart. § 202.2.14 describes a building that is not a multiple-family dwelling and contains more than 2 rooming units, occupied by individuals who do not form a single housekeeping unit and do not provide compensation under a single lease.
Fair housing reaches people applying together. Article 4, § 3-5(a)(9) lists a refusal "to consider 2 or more applicants' incomes when they seek to buy or rent a dwelling or dwelling unit" among practices unlawful when done because of a protected trait such as marital status or familial status. § 3-5(j) leaves occupancy limits in place, and § 3-5(i) exempts some owner-occupied settings.
The city code index on that site reads Current through July 17, 2026. We describe these city sections as enacted and do not predict how the city applies them to a particular household.
Our record of Maryland's Real Property Article finds no deadline for this notice, which leaves the lease as the place a deadline would be written.
Under § 8-5A-01(c) a legal occupant resides there "with the actual knowledge and permission of the landlord", the status the abuse exit in § 8-5A-02(a) relies on.
Zoning Code § 1-306(g)(3) says a family "does not include, in any case" more than 4 unrelated people.
§ 404.4.1 requires at least 70 sq. ft. for a bedroom occupied by 1 person and 50 square feet for each occupant of a shared bedroom.

Red Flags to Watch Out For
-
A Maryland notice deadline with no section number
If you are told Maryland law fixes a deadline for reporting a roommate, ask which section. Our record of the Real Property Article finds no deadline for that notice.
-
A fifth unrelated adult moving in
§ 1-306(g)(3) says a family does not include, in any case, more than 4 unrelated people. The definition as our record quotes it says nothing of a landlord's approval.
-
Roomers taken in by a group of friends
The 2 roomers allowed under § 1-306(g) attach to an individual or to related people sharing a common entrance and cooking and bathroom facilities, not to a group of unrelated housemates.
-
A roommate the landlord never heard about
§ 8-5A-01(c) defines a legal occupant by the landlord's actual knowledge and permission. Someone living there unannounced is not who that definition describes.
-
Two sleepers in a box room
§ 404.4.1 requires at least 50 square feet for each occupant of a shared bedroom, so the minimum for a room grows with each person sleeping in it.
Your Rights as a Baltimore Tenant
-
A named status for a known occupant
§ 8-5A-01(c) defines a legal occupant as "an occupant who resides on the premises with the actual knowledge and permission of the landlord".
-
An abuse exit that counts occupants
Under § 8-5A-02(a) a tenant may terminate future liability under a residential lease if the tenant or a legal occupant is a victim of abuse, subject to the subtitle's notice requirements.
-
Joint incomes on fair housing terms
Article 4, § 3-5(a)(9) lists a refusal to consider 2 or more applicants' incomes, when done because of a protected trait such as marital or familial status, as an unlawful practice.
-
Space measured, not guessed
§ 404.4.1 sets 70 sq. ft. for a one-person bedroom and 50 square feet per occupant of a shared one, and § 404.9 sets 240 square feet for a dwelling unit.
What To Do - Step by Step
Read the occupancy and guest paragraphs
Find who may live there, whether approval is needed and whether a deadline is stated. Our record of Maryland's Real Property Article finds no deadline, which leaves those paragraphs as the text that answers it.
Count the household against the zoning definition
Zoning Code § 1-306(g) counts a group of not more than 4 unrelated people as one family. Check where the new person falls before anyone moves boxes.
Measure each bedroom
§ 404.4.1 requires 70 sq. ft. for one sleeper and 50 square feet for each sleeper in a shared room. Floor length times width gives the figure to compare.
Tell the landlord in writing
Name the person and the move-in date. A legal occupant under § 8-5A-01(c) lives there with the landlord's actual knowledge and permission, so keep the request and the reply with your lease.
Apply together if you are renting together
Article 4, § 3-5(a)(9) reaches a refusal to consider 2 or more applicants' incomes when it is made because of a protected trait. § 3-5(i) exempts some owner-occupied buildings.
Check the current text before relying on it
Read § 8-5A-01 and § 8-5A-02 in the General Assembly's current text, and § 1-306 and § 404 on codes.baltimorecity.gov, whose index read Current through July 17, 2026.
