What to Do When Your Roommate Smokes in the Apartment

You walked in after class and the whole apartment smells like a hot box. Or stale cigarettes. Or both. Your clothes hanging in your closet now smell like it. Your security deposit is suddenly in question. And the conversation you’ve been avoiding just became unavoidable.

When your roommate smokes in the apartment, you have three real moves: address it directly in a calm conversation, put a written rule in place that matches your lease, and — if neither works — involve the landlord. You’re not the bad guy for caring about this. Indoor smoke is a health and money problem, not a vibe issue.

What does your lease actually say?

Read it before you do anything else. Most leases in 2026 have an explicit no-smoking clause, and many cover weed even in states where it’s legal. The lease is your strongest piece of leverage and most renters never look at it.

Things to check:

• Is there a no-smoking clause? Does it cover indoor only, or the whole property including balconies?
• Does it specifically mention cannabis, vaping, or just “smoking”?
• What’s the penalty? Many leases mention loss of security deposit, fines, or grounds for eviction.

Screenshot the relevant paragraph. You’ll want it for the conversation and, if it comes to it, for the landlord.

How do you tell your roommate to stop smoking inside?

Talk to them in person, when no one’s high or hungover, and frame it around the lease and the deposit — not their habits.

You’re not telling them to quit. You’re telling them where they can do it. That’s a much easier ask.

The script:

“Hey, I checked the lease and there’s a no-smoking clause that puts our deposit at risk. Can we agree smoking happens outside or on the balcony? I don’t care that you smoke, I just don’t want us to lose two grand when we move out.”

What this does: it makes the lease the bad guy, not you. It gives them an option (outside, balcony). It puts a number on the cost. Most people will agree to this because nobody wants to lose their deposit.

What if they agree and then keep doing it anyway?

Document everything. This isn’t dramatic, it’s necessary.

Every time it happens, write down the date and time in a note on your phone. If you can, take a photo of an ashtray or a clear sign it happened indoors. If the smell is bad enough to affect your stuff, note that too.

After the second or third incident, send a text — not a confrontation, just a record. “Hey, smelled smoke inside again last night around 11. Just flagging.” Now you have a paper trail.

Why this matters: if you have to involve the landlord or break the lease, “trust me bro” doesn’t fly. Documented dates and a previous written agreement do.

When to involve the landlord

Three signs it’s time:

1. You’ve had the conversation twice and nothing changed.
2. The smell is in your belongings or affecting your sleep, work, or health.
3. You’re worried the deposit is already gone.

When you contact the landlord, keep it factual. Don’t rant. “Hi, I’m writing because my roommate has been smoking inside the unit despite our lease’s no-smoking clause. I’ve raised it with them twice. I want to flag this in writing so it’s documented.” That’s it.

The landlord’s response will tell you where you stand. Some will mediate. Some will issue a warning to the unit. A few will move toward eviction proceedings if it’s bad. None of those are your fault — they’re consequences of breaking the lease.

What about your security deposit?

If smoke residue is on the walls, ceiling, or carpets when you move out, the landlord will absolutely deduct from the deposit. They might deduct the entire thing for cleaning and repainting.

Before move-out, do a walkthrough with your phone camera. Photo every room, every wall, every ceiling. Note the smell. If your roommate caused the damage, you can argue (sometimes successfully) for the deduction to come out of their share, especially if you have your documented texts and notes.

Don’t wait until move-out day to think about this. The damage is being done now.

When to start planning your exit

Some people aren’t going to change their habits, and that’s a hard truth to accept. If smoking indoors is non-negotiable for them and intolerable for you, the math is simple: this isn’t a fit.

You can wait out the lease, find a sublet, or start the harder conversation. See how to ask a roommate to move out for that one.

How homies helps

homies gives you a shared house rules space where things like “no indoor smoking” live as actual agreed-on rules, not vague hopes from move-in day. The AI mediator can help you draft the conversation when you don’t know how to start, and the timeline of issues stays in the app so you’re not the one tracking dates in a Notes file.
