Mold in Apartments and Condos: Who’s Responsible for Removal?

Mold can be a serious issue in shared living spaces like apartments and condominiums — and in New Jersey, where humidity and seasonal weather swings are common, it’s not unusual for tenants or condo owners to discover it lurking in walls, basements, or around leaky windows. But when it shows up, one big question follows: Who’s responsible for mold removal?

At Quest Air Mold Remediation, we’ve worked with both renters and property managers across NJ to help resolve these issues. Here’s a breakdown of what you need to know.


Renters in New Jersey: Know Your Rights

If you’re renting, your landlord is typically responsible for maintaining a safe and habitable living space. That includes addressing mold caused by leaks, structural issues, or poor ventilation.

When the landlord is responsible:

  • Mold results from a plumbing leak or roof issue

  • Mold appears around windows due to poor sealing or insulation

  • The HVAC system is spreading mold spores through the vents

When tenants may share responsibility:

  • Mold develops from poor housekeeping (e.g., leaving wet items on floors)

  • The bathroom isn’t ventilated after showers

  • Food or garbage is left out for extended periods

In most NJ towns, landlords are required to act promptly once they’re notified of a mold problem. If they delay or ignore it, you may have grounds to file a complaint with your local housing department.


Condo Owners: A Shared Responsibility

Condominium living adds another layer of complexity. You own your unit — but shared walls, roofs, and pipes can mean mold may originate from outside your space.

Here’s a general guide:

Unit owner’s responsibility:

  • Mold from personal appliances (dishwasher, washing machine)

  • Issues caused by interior maintenance lapses

Condo association’s responsibility:

  • Mold from roof leaks or exterior wall cracks

  • Shared plumbing leaks between units

  • Improper drainage or ventilation in common areas

It’s important to review your condo’s bylaws or speak with the association to determine coverage. Many NJ condo boards have specific mold remediation protocols and insurance policies in place.


What to Do If You Discover Mold in Your Apartment or Condo

  1. Document everything — Take photos and note the date you noticed the mold.

  2. Notify your landlord or condo board in writing — This creates a paper trail.

  3. Schedule a professional mold inspection — Especially if the source is unclear.

  4. Avoid DIY cleanup — Especially with black mold or widespread growth, improper cleaning can make the problem worse.
