Roommate Agreement vs Lease: What's the Difference?
You signed a lease. Do you still need a roommate agreement? Yes. Here's why they're completely different documents — and why you need both.
Lease
Between you and your landlord. Covers: rent amount, lease term, security deposit, landlord obligations, eviction terms. Does NOT cover: who does dishes, guest policies, or how utilities are split between roommates.
Roommate Agreement
Between you and your roommates. Covers: rent split, chore schedule, guest policy, quiet hours, shared items, move-out notice. Does NOT replace the lease — it's an additional layer.
Why Your Lease Isn't Enough
Your lease says you owe $3,000/month to the landlord. It doesn't say each roommate pays $1,000. If one roommate doesn't pay, the landlord can come after any of you for the full amount. A roommate agreement creates a separate legal obligation between roommates — you can take your non-paying roommate to small claims court based on your signed agreement.
What Happens When There's No Agreement
Without a written agreement, disputes default to "he said, she said." Who agreed to pay what? Who was supposed to clean the bathroom? Did everyone agree the boyfriend could move in? Verbal agreements are almost impossible to enforce.
Can a Roommate Agreement Override a Lease?
No. A roommate agreement can't override the terms of your lease. If your lease says no pets, your roommate agreement can't allow pets. But it can add rules the lease doesn't cover — like how pet costs are split or who walks the dog.
