The short answer
Health Risks of Mold
Mold releases spores and volatile compounds that can irritate your eyes, skin, nose, and throat. For people with asthma or allergies, exposure can trigger coughing, wheezing, and more severe reactions. Even if you feel fine now, prolonged exposure can lead to new sensitivities or worsen existing conditions.
Some molds produce mycotoxins, which are more concerning, but you cannot tell by sight which mold is present. If you or your family members have chronic health issues, the risk is higher. See a doctor if you feel unwell after moving in or after visiting the basement.
Assess the Extent of Mold
A small patch of mold on a wall might be a quick fix, but mold that covers large areas or has spread into porous materials like drywall or carpet is a bigger problem. You need to know if the mold is a symptom of ongoing moisture, such as a leaking pipe or poor drainage.
Look for water stains, musty odors, and damp spots. Ask the landlord about past flooding or leaks. If the mold is widespread, it suggests a chronic moisture issue that will likely return unless the source is fixed. A professional inspection can identify the moisture source and the extent of contamination.
- Visible mold growth larger than a few square feet
- Musty or earthy smell in the air
- Water stains on ceilings or walls
- Warped or discolored flooring
- Condensation on windows or pipes
- Cracks in foundation or walls
Landlord Responsibilities
In most places, landlords are required to provide a habitable living space, and mold that poses a health risk may violate that duty. You have the right to ask for the mold to be removed before you move in. Get any agreement in writing, including what will be cleaned and when.
If the landlord refuses to address the mold, you may have legal options, but those vary by state and local law. Check your lease and local tenant protections. You can also ask for a mold inspection by a qualified professional to document the problem, which can be useful if you need to break a lease.
Before You Sign
Do not rely on the landlord's assurance that the mold is harmless. Ask to see the basement before the lease starts, and if mold is present, request that it be remediated by a professional. You can also ask for the moisture source to be fixed, such as repairing a leak or improving drainage.
If the landlord agrees to clean the mold, ask how it will be done. Simply painting over mold does not solve the problem. The mold must be removed, and the surface dried and treated. After remediation, you may want to have the area re-inspected to confirm the mold is gone.
When to Walk Away
If the mold is extensive, if the landlord is unwilling to fix the moisture problem, or if you have health concerns that make mold a significant risk, it may be sensible to find another place. Your health is not worth the risk. A basement with a history of flooding or persistent dampness is a red flag.
Consider the climate: in a mild marine climate with wet winters, basements can stay damp for long stretches. Look for a basement that has been properly waterproofed and has good ventilation. If the basement feels damp or smells musty, that is a sign the mold problem may be ongoing.

Can I remove the mold myself?
You can clean small patches of mold (less than a few feet) with soap and water, but you must wear gloves and a mask. If the mold is extensive or if you have health issues, hire a professional mold remediator. Do not disturb large areas, as that can release more spores.
What should I do if I already signed a lease and found mold?
Document the mold with photos and notify your landlord in writing. Ask them to remediate the mold and fix the moisture source. If the landlord does not act, you may have legal options, but those vary by state. See a doctor if you experience health symptoms.
Will my insurance cover mold damage?
Policies vary, and your insurer decides what is covered. Renters insurance may cover personal property damaged by mold, but only if the mold is caused by a covered peril, like a burst pipe. Check your policy and ask your insurer about mold coverage.
