Mold in Your Apartment: Your Rights and What to Do
Ongoing mold, especially from a leak or moisture problem the landlord hasn't fixed, is generally treated as a habitability issue. Document it, report it in writing, and Renter Shield can show you what happens next where you live.

What this means
Finding mold in your home is unsettling, and it's a common enough problem that you're far from alone. Small amounts of surface mildew in a bathroom are usually just a cleaning issue, but mold that keeps coming back, covers a large area, or comes with a musty smell throughout a room is a different story — especially if it's tied to a leak, poor ventilation, or a moisture problem the building isn't handling.
In most places, a rental is expected to be safe and livable, and that generally includes being reasonably free of serious mold problems — particularly when the mold is caused by something the landlord is responsible for, like a roof leak, plumbing leak, or a structural moisture issue. Mold linked to a health condition, like a respiratory issue, is generally taken more seriously than a small cosmetic spot.
Who's responsible for cleanup can depend on the cause. Mold from a maintenance issue (a hidden leak, poor drainage, a failing exterior wall) generally falls on the landlord to fix. Mold from something within the tenant's control, like never running a bathroom fan or letting standing water sit, can be viewed differently — so a clear, factual written report matters.
There's no single national number of days a landlord has to respond to a mold report — it depends on your state and the severity of the problem. Renter Shield shows the specific rule and options for where you live instead of leaving you to guess.
What to do
- Take dated photos and, if you can, video of the mold, including how much area it covers and anything nearby that might be causing it, like a leak or window condensation.
- Notify your landlord in writing (email or text is fine) describing where the mold is, when you first noticed it, and any related issue like a leak or musty smell. Keep a copy.
- Note any health symptoms that seem connected, especially for children, older adults, or anyone with asthma or allergies, and keep a simple log.
- Ask about professional testing or remediation if the area is large — store-bought sprays rarely fix mold caused by an ongoing moisture source.
- Keep every message, photo, and reply together in one place so you have a full record if you need to escalate.
- If your landlord doesn't respond, Renter Shield can show you the escalation options recognized in your state, and lawhelp.org or 211 can connect you to free local help.
