Roommate's Friend Is Always at Your Apartment? Do This

There’s a person you didn’t sign a lease with who has now been on your couch for sixteen of the last twenty days. They have their own toothbrush in the bathroom. They know where the snacks are. Your roommate hasn’t said anything about it, like this is normal. It is not normal.

If your roommate’s friend is always at your apartment, the fix is one direct conversation with your roommate (not the friend), a clear rule on overnight stays, and — if it’s gone on this long — a real talk about a fair share of bills and groceries. You’re allowed to have this conversation. You’re paying rent, not running a hostel.

Here’s how to handle it without nuking the roommate relationship.

When does a friend become an unofficial roommate?

There’s no exact line, but most leases consider someone a guest until they hit one of these:

• Sleeping over more than 3 nights a week, consistently
• Receiving mail or packages at the address
• Having a key or knowing the door code
• Keeping clothes, toiletries, or food in the apartment
• Being there when your roommate isn’t

Hit two or three of those and they’re functionally living there, not visiting. Most leases cap “guest” stays at 10-14 days per month. After that, your landlord can technically classify them as an unauthorized occupant — which is a problem for everyone on the lease, not just your roommate.

This isn’t about being uptight. It’s about the fact that you didn’t agree to live with this person, and now you are.

How to talk to your roommate about it (not the friend)

Talk to your roommate. Never the friend. The friend is a guest in someone else’s home — your problem is with the person who invited them.

Pick a time when the friend isn’t there. Don’t ambush, don’t text. Sit down for two minutes. Use a version of this:

“Hey, I’ve been meaning to bring this up. [Friend] has been over a lot — which is fine, I like them — but it’s started feeling like they live here. Can we set a guest rule we both stick to? Like, no more than three nights a week unless we both agree in advance.”

Notice the structure: you’re not attacking the friend, you’re proposing a rule. “Can we” instead of “you need to.” You’d want the same courtesy if it was your friend.

If your roommate gets defensive, that’s information. People who are okay with shared living don’t react like that. People who’ve quietly turned a 2-person apartment into a 3-person one do.

What if the friend is eating your food or using your stuff?

Two separate problems. The friend being there a lot is one issue. The friend treating your apartment like an Airbnb is another. Both need addressing, both with your roommate.

What to bring up:

• Groceries. If the friend is eating shared food, they should be chipping in. Or your roommate should be buying enough for two people. Either way, your grocery bill shouldn’t be subsidizing them.
• Utilities. Three people in an apartment use more water, more electricity, more wifi than two. If you’re splitting bills 50/50, you’re now paying for a person you didn’t agree to host.
• Toiletries and supplies. Toilet paper, paper towels, dish soap. If the friend is using them, they should be replacing them. If they’re not, your roommate should be.
• Common space. The couch, the kitchen, the bathroom — you’re entitled to use them without working around a third person.

A script that works: “I want to keep things chill, but [Friend] being here this much is bumping our utility and grocery costs. Either they need to start chipping in, or we should cut back on the overnight stays.”

That’s a real ask, with two real options. Hard to argue with.

What if your roommate refuses to set a limit?

If you’ve asked once, asked twice, and nothing changed, you’re now dealing with two roommates instead of one — and only one of them is on the lease. Your options:

1. Escalate in writing. Send a text recapping the conversation and the rule you agreed on. Now it’s documented.
2. Loop in the landlord. Most leases have a guest clause. The landlord doesn’t want unauthorized occupants either. This is nuclear, only use it if the friend is causing actual problems.
3. Renegotiate the rent. If a third person lives here, they should pay third-person money. Either they go on the lease and split rent, or they stop staying over.
4. Plan your exit. If none of the above works, this isn’t a livable situation. How to ask a roommate to move out covers what comes next.

You’re not being dramatic. You signed a lease for a two-person place.
