Living in Portland often means dealing with old buildings and their quirky charms. But for some tenants, that charm turns into a nightmare when the scratching in the walls becomes impossible to ignore. Lately, there’s been a lot of talk about a Portland apartment mice lawsuit, and honestly, the details are enough to make anyone’s skin crawl. It’s not just about a stray mouse in the kitchen; we’re talking about systemic neglect that has led to full-blown infestations and legal showdowns.
Oregon law is actually pretty clear about this, even if some landlords act like it isn’t. Under ORS 90.320, your landlord is legally required to keep your place "habitable." That fancy legal word basically means the apartment needs to be safe, clean, and—most importantly—free from rodents and vermin. If you move in and the place is already crawling with mice, that’s a direct violation of the law from day one.
Why the Portland Apartment Mice Lawsuit is Bubbling Up Now
You might be wondering why this is hitting the fan right now. Portland has seen a surge in habitability complaints over the last few years. High-profile cases, like the ongoing issues at Milepost 5, have highlighted how even large-scale housing projects can fall into disrepair. In late 2024 and throughout 2025, investigations found units infested with roaches and rodents, with some residents resorting to staying up all night with the lights on just to keep the pests at bay.
When things get that bad, a simple "please fix this" email usually doesn't cut it. Tenants are starting to realize that collective action is often the only way to get a landlord’s attention. A Portland apartment mice lawsuit usually isn't just about one person; it’s about a pattern of neglect.

The Real Cost of a Mouse Infestation
It’s easy for a property manager to say, "Oh, it’s just a mouse, we’ll set some traps." But for the people living there, it’s a health hazard.
- Property Damage: Mice love chewing on wires. This isn't just a nuisance; it’s a massive fire risk.
- Disease: We're talking Hantavirus, Salmonellosis, and other nasty stuff spread through droppings and urine.
- Mental Toll: Imagine trying to sleep while hearing scratching inches from your head. It’s exhausting.
Kinda makes you realize why people are suing, right? If you’re paying $1,800 a month for a one-bedroom in the Pearl or SE Portland, you expect a home that doesn't come with "unwanted roommates."
What the Law Actually Says (ORS 90.320)
Let’s get into the weeds for a second. In Oregon, the Warranty of Habitability is your best friend. Your landlord must ensure the building is free from rodents at the start of the lease. They also have to maintain the common areas. If the mice are coming through holes in the exterior walls or common hallways, that’s 100% on the landlord.

The tricky part? If the landlord can prove you caused the infestation—maybe by leaving heaps of trash or pet food everywhere—they might try to flip the bill on you. But if it’s a structural issue, like gaps in the foundation or poorly sealed doors, they don't have a leg to stand on.
Can You Withhold Rent?
This is where people get into trouble. Do not just stop paying rent. If you do, the landlord can slap you with an eviction notice for non-payment, and suddenly you’re the one on the defensive in court. Instead, you have to follow a very specific process. You need to give written notice. Not a text, not a phone call—a real, dated letter. Tell them exactly what’s wrong and give them a reasonable amount of time to fix it.
In Portland, if they don't act, you might be able to use the "repair and deduct" rule, but there are limits. Usually, it’s capped at around $300, which honestly won't cover a serious mouse problem that requires professional exclusion work. This is why many tenants end up looking at a Portland apartment mice lawsuit to recover damages for "diminution of value"—basically, you paid for a luxury apartment but got a rodent-filled box, so you want your money back.

The Role of the Portland Housing Bureau
There’s been some drama here lately, too. In late 2025, it came out that the Portland Housing Bureau was sitting on nearly $20 million in unspent funds from rental registration fees. This money was supposed to go toward things like eviction protection and helping renters. The fact that this money was just sitting there while people lived in sub-standard conditions has made a lot of folks very angry. It also means there might be more resources coming soon for legal aid to help with these types of lawsuits.
What to Do If Your Apartment Has Mice
If you’re currently dealing with this, you’ve got to be your own private investigator. Start taking photos of everything. Droppings, chewed baseboards, actual mice if you can catch them on camera.
- Document everything: Save every email and take photos of every mouse sighting.
- Written Notice: Send a formal "Notice of Habitability Violation."
- Call Inspectors: Contact the City of Portland’s Bureau of Development Services. If they find a code violation, that’s "exhibit A" for your lawsuit.
- Talk to your neighbors: If everyone in the building has mice, a group lawsuit is way more powerful than a solo one.
A Portland apartment mice lawsuit can take a long time to wind through the courts. Most landlords will try to settle before it gets to a jury because, honestly, no one wants a public record of their building being a "mouse house."
Actionable Steps for Portland Renters
Don't wait until the mice have taken over your pantry to act. If you see one, there are likely ten more you don't see.
- Check your lease: See what it says about pest control. Even if it says you’re responsible, state law (ORS 90.320) often overrides those "illegal" clauses if the building itself is the problem.
- Reach out for legal help: Organizations like the Community Alliance of Tenants (CAT) or Legal Aid Services of Oregon can give you the lowdown on your specific rights.
- Keep your receipts: If you had to buy traps, sealers, or throw away contaminated food, keep every single receipt. You’ll want that money back in a settlement.
At the end of the day, you have a right to a home that doesn't make you sick. The recent wave of legal actions in Portland shows that the "city of roses" is starting to get serious about holding negligent landlords accountable for the pests they ignore. If you're living with mice, start the paper trail now. It's the only way to protect your health and your wallet.
