Roommate Agreement vs. Lease: Know the Difference
A roommate agreement is a contract between the people who live together. It does not replace the lease you signed with the landlord — it sits alongside it and settles the questions the lease doesn't answer: who pays what share, who does which chores, and how the household makes decisions.
That distinction matters when money is involved. If everyone is on the lease, each roommate is jointly responsible for the full rent to the landlord — so if one person leaves, the others still owe the total. If only one person is on the lease and sublets a room, the subtenant's obligations run to the leaseholder, not the landlord, unless the landlord approves otherwise. Check whether your lease allows subletting and roommates at all before you move anyone in.
The generator on this page builds a roommate agreement from the details you enter. For the landlord-facing document, see our room rental agreement tool, and for formal subleases see the sublease agreement.
What to Include in a Roommate Agreement
A good roommate agreement covers the practical details that cause most household conflict, so everyone is on the same page from day one:
- ✓Rent split: each person's share, due date, and how to pay
- ✓Bills: utilities, internet, and who pays or who splits what
- ✓Chores: cleaning schedule and who owns which shared spaces
- ✓Guests: visits, overnight stays, and how long guests may stay
- ✓Quiet hours: when noise stays down, especially on weeknights
- ✓Shared items: food, supplies, and who buys what
- ✓Subletting: whether a roommate may bring in someone to replace them
- ✓Dispute process: how conflicts get raised and resolved
Add a section on what happens if one roommate leaves: how much notice is required, whether they keep paying their share until a replacement is found, and how the security deposit is returned. Agreeing on this before it happens is much easier than negotiating it mid-move-out.
How to Fill In the Form
- 1. List every roommate. Include full legal names of everyone who lives there, and note who is on the lease versus who is subletting.
- 2. Agree on money first. Rent split, utility split, and deposits are the most common source of roommate conflict — settle them before anything else.
- 3. Make the house rules specific. Chores, guests, and quiet hours only work when they are concrete enough to follow without interpretation.
- 4. Review, download, and sign. Preview the document, download the PDF, and have every roommate sign and keep a copy.
State Rules Vary — Check Yours
Roommate agreements are governed mostly by contract law plus the landlord-tenant rules in your state, and those rules vary widely — deposit handling, notice periods, and who counts as a tenant all differ. We don't print one-size-fits-all numbers here. Visit our state agreement pages for guides to the rules where you are, and for a deeper walkthrough see our how to write a room rental agreement guide, which covers roommate setups too.
Frequently Asked Questions
Is a roommate agreement legally binding?
Yes — a signed agreement between the roommates is enforceable as a contract. It doesn't override the lease or state law, and it isn't legal advice, but courts generally uphold clear, signed agreements about rent sharing and house rules.
What if one roommate stops paying rent?
If everyone is on the lease, the landlord can pursue the full rent from any roommate, so the others may need to cover the shortfall and recover from the departing roommate. A written agreement documenting each person's share makes that recovery much easier.
Can a roommate add a new person without asking?
Only if the agreement allows it. Put a rule in writing that new roommates need unanimous consent and landlord approval where the lease requires it.
Do I need a lease to have a roommate agreement?
No — the agreement works on its own, but you should also make sure the housing arrangement itself is legal. If you are subletting, check your lease and consider a formal sublease agreement.
