How can I prevent mold growth?
Back to topTo help prevent the growth of mold and mildew in residential spaces, it is essential that resident students do the following:
- Keep windows closed.
- Set thermostats between 68 to 75 degrees Fahrenheit. Please note that some buildings’ thermostats are set to provide protections against these substances and cannot be changed below or above a certain temperature.
- Keep bathroom doors closed while showering.
- Keep air vents unobstructed.
- Hang wet towels or clothing to allow them to dry. Please note that hanging a wet towel that touches a wall can accelerate growth process with these substances. Make sure your wet towels do not come in contact with any porous materials, like walls, as they dry.
- Keep all surfaces, furniture, and clothing dry.
- Routinely clean bathroom areas to prevent the growth of soap scum or buildup of mildew (Community bathrooms are cleaned daily by maintenance staff).
- Report any water problems (leaks, dripping faucets, wet carpet, drips heard behind the air intake cover, etc.) immediately by submitting a Maintenance Request via the Housing Portal.
- Allow University Housing or its contractors to enter the room to inspect and make necessary repairs.

What can I do to treat mold?
Back to topIf you see or smell mold, you should remove it. You do not need to know the type of mold. If mold is growing in your home, you need to clean up the mold and fix the moisture problem.
Mold can be removed from hard surfaces with household products, soap and water, or a bleach solution of no more than 1 cup of household laundry bleach in 1 gallon of water.
If you use bleach
- Never mix bleach with ammonia or other cleaners. This will produce a poisonous gas.
- Follow manufacturers' instructions when you use bleach or any other cleaning product.
- Open windows and doors to provide fresh air.
- Wear rubber boots, rubber gloves, and goggles during cleanup.

Mold Regulations
The EPA does not set any federal exposure limits, permissible spore counts, or enforceable regulations for mold. EPA mold documents are guidance only, not legal standards.
This means:
There are no federal thresholds like “X spores per cubic meter.”
There are no required cleanup mandates or legally binding remediation procedures.
The EPA’s information is recommendations, often used as industry best practice.
Pennsylvania has no state laws that directly regulate mold, set exposure limits, or require landlords to test, prevent, or remediate mold. -
Mold Test Kits
CDC does not recommend mold testing.
DIY mold test kits fail to provide reliable results. They confirm the presence of mold without indicating whether the levels are dangerous or normal, as mold spores are everywhere in both indoor and outdoor environments.
Additionally, the health effects of mold are different for different people so you cannot rely on sampling and culturing to know whether someone might become sick. No matter what type of mold is present, you need to remove it.
