Moving into a dorm or apartment this fall? Here's how to check for mold before you unpack.

Back to school season is here, and we've heard some stories about college students getting exposed to mold in their dorms, sororities, and student housing. So we figured we'd put together a practical list before everyone gets settled in.

Look for:

  • Water stains or discoloration on ceiling tiles or around windows
  • Musty smell in closets, under sinks, or near AC units (even faint)
  • Peeling paint or bubbling drywall
  • Visible spots in bathroom grout that won't scrub off
  • Condensation on windows or walls

Ask about:

  • Any recent leaks, flooding, or water damage in the unit (landlords/RAs have to disclose some of this depending on your state)
  • How old the AC/HVAC system is and when it was last serviced

Pay attention to your body:

  • Sinus issues, headaches, or fatigue that show up specifically after being in the space for a while
  • Symptoms that ease up when you leave and come back when you return

If you find something, or you're not feeling great in the space:

  • Document what you're seeing (photos, notes on when symptoms happen)
  • Let your landlord or RA know so it's on record
  • If you want more clarity, testing options exist (air quality, surface swabs, at-home panels)

Ways to manage exposure if moving isn't an option:

  • Keep humidity below 50% with a small dehumidifier if the space runs damp
  • Run the AC or a fan to keep air moving, especially in bathrooms and closets
  • Wipe down window sills and any condensation regularly
  • Use an air purifier with a HEPA filter if you can swing one
  • Keep a moisture absorber (like DampRid) in problem spots like closets

Are you heading back to school yourself, or helping your kid move? Curious if anyone's dealt with mold in student housing, we'd love to hear your stories, experiences, or tips from past move-ins.
