I've been splitting rent proportionally for years. By room size, by amenities, by whatever metric makes the math fair. But I've always had this nagging question in the back of my head: is this actually legal? Can a landlord charge different amounts for different rooms? Can roommates agree to pay different shares without getting in trouble?
I spent $150 on a 30-minute consultation with a landlord-tenant lawyer in Portland to get a real answer. Here's what I learned, and why I think every roommate should know this.
The short answer: yes, it's legal. The longer answer: it depends on how your lease is structured.
If you're all on one lease — which most roommate situations are — the lease says the total rent is $3,000 (or whatever). It doesn't say each person pays $1,000. It says the group pays $3,000. How you split that $3,000 among yourselves is entirely up to you. The landlord doesn't care as long as the full amount shows up on time.
This means you can absolutely charge more for the master bedroom and less for the closet room. You can charge couples more than singles. You can charge by income, by square footage, or by a complex algorithm that factors in bathroom proximity and natural light. The landlord doesn't care. The law doesn't care. It's a private agreement between roommates.
Where it gets complicated is if someone moves out. If Kevin is paying $1,200 for the master suite and Sarah is paying $600 for the small room, and Kevin moves out, the landlord still wants $3,000. Sarah can't suddenly say "well I was only paying $600 so that's all I owe." The lease says $3,000. Everyone on the lease is responsible for the full amount.
The lawyer told me the most common legal issue with roommate rent splits isn't the split itself. It's what happens when someone leaves. If you have a written agreement about who pays what, and someone stops paying, the other roommates can sue the non-paying roommate in small claims court. But they still have to pay the landlord first, because the landlord's lease trumps the roommate agreement.
He also told me something I didn't expect: some landlords actually prefer proportional splits because it reduces turnover. If the person in the small room is paying a fair price, they're less likely to move out quickly. If they're overpaying, they'll leave as soon as they can, and the landlord has to find a new tenant.
So yes, it's legal. Yes, you should do it if your rooms are different sizes. And yes, you should get it in writing so that when someone inevitably asks "why do I pay more?" you can point to the document instead of having the same argument every month.
The $150 was worth it for peace of mind. And now I can tell people "my lawyer said it's fine" which is a fun sentence to say at parties.
