Sharing a rental?. Create a roommate agreement →
When you rent to roommates, you have three basic setups: one joint lease that every roommate signs, separate leases for each room, or a lease with one tenant who brings in roommates under a sublease. For most small landlords, a joint lease with a joint and several liability clause is simplest: each roommate is responsible for the full rent and any damage, not just their share. The roommates can then divide rent, bills and chores among themselves in a separate roommate agreement, which you don't sign.
This guide compares the setups, explains the clauses that matter, and covers what to do when a roommate leaves or a new one moves in.
Three ways to rent to roommates
| Setup | How it works | Good for | Watch out for |
|---|---|---|---|
| Joint lease | All roommates sign one lease for the whole unit | Most houses and apartments shared by a group | One roommate leaving doesn't end the lease for the others; you need a process for replacements |
| Individual leases (by the room) | Each roommate leases a bedroom plus shared use of common areas | Larger houses, student housing, co-living | More paperwork; you fill vacancies room by room and handle disputes between roommates |
| Master tenant + sublease | One tenant signs the lease and sublets rooms to others | When one roommate wants control and you approve subletting | You have no lease with the subtenants; see subletting rules for landlords |
The joint lease: clauses that matter
Joint and several liability
The single most important clause:
Each Tenant is jointly and severally liable for all obligations under this lease, including the full rent, and not only for a share of it.
With it, if one roommate stops paying, you can collect the full rent from any of them. Without clear language, you may end up arguing about who owed what.
Who may live there
List every adult occupant by name, and say that anyone else staying more than a set number of nights needs your written approval. Set occupancy limits by bedroom based on your local code. HUD's long-standing occupancy guidance treats two persons per bedroom as a generally reasonable starting point, subject to factors like bedroom size and local law (HUD, Fair Housing Enforcement: Occupancy Standards).
One rent payment, or several?
You can require a single payment for the full rent, or accept separate payments from each roommate. A single payment is easier to track. If you take separate payments, record each one, and remember that under joint and several liability a shortfall is still owed by everyone.
Notices
Say that a notice to one tenant counts as notice to all, and that any one tenant's notice to end the tenancy needs to be signed by all of them to end the lease. Check your state's rules on notice; landlord notice to vacate by state covers ending tenancies.
Security deposit
Take one deposit for the unit, not separate deposits per roommate, unless you use individual leases. State in the lease that the deposit is returned at the end of the tenancy, not when one roommate leaves, and how you'll pay it out (one check to all tenants, or split as they jointly direct in writing). Your state's deposit rules still apply; see security deposit laws by state.

Screening roommates
Screen every adult who will live in the unit, with the same criteria you use for any applicant. For income, decide in advance whether you'll count combined household income, and apply that rule to every group. A rental application for each adult keeps it consistent. How to screen tenants covers the full process.
When a roommate wants to leave
Under a joint lease, a departing roommate is still on the hook until you release them in writing. Handle it with a short, signed process:
- The remaining roommates find a replacement, who applies and is screened.
- If you approve, everyone signs a lease amendment removing the departing roommate and adding the new one, effective on a set date.
- The roommates settle the deposit share among themselves. You keep the deposit for the unit as a whole.
- If you don't approve a replacement, the remaining roommates stay responsible for the full rent.
If a roommate simply leaves without a replacement, the others still owe the full rent under joint and several liability. Talk to them early about whether they can cover it.
Adding a roommate mid-lease
Treat it like a new application: screen the person, then add them to the lease by a signed amendment. An occupant who isn't on the lease isn't bound by it, which makes problems hard to enforce. The lease addendum guide explains roommate addenda.
The roommates' own agreement
Separately, roommates often sign a roommate agreement among themselves covering:
- How rent and the deposit are split
- How utilities, internet and shared supplies are paid
- Quiet hours, guests and overnight visitors
- Cleaning and chores
- Parking and storage
- What happens if one of them wants to leave
This agreement is between the roommates. It doesn't change what they owe you under the lease, but it reduces the disputes that end up at your door.
Common mistakes
- No joint and several clause, so each roommate argues they owed only their share
- An adult living there who never signed the lease
- Returning one roommate's deposit share early, then finding damage at move-out
- Approving a replacement verbally without a signed amendment

Frequently asked questions
What does joint and several liability mean on a roommate lease?
Each roommate is responsible for the entire rent and any damage, not just a share. If one roommate stops paying, the landlord can collect the full amount from any of the others.
How do I replace a roommate on a joint lease?
Screen the replacement like any applicant, then have everyone sign a lease amendment removing the departing roommate and adding the new one on a set date. Keep the deposit for the unit as a whole and let the roommates settle shares among themselves.
