Tenant Rights: What to Do If You Find Mold in Your Rental Unit

New York City tenants have some of the strongest housing protections in the country, yet many renters feel powerless when they discover mold. You might fear eviction, rent hikes, or simply being ignored by a busy management company.

But here is the truth: You have the right to a mold-free home.

In NYC, mold is not considered a “lifestyle choice” or a housekeeping issue; it is a legal violation. Under the Warranty of Habitability and Local Law 55, your landlord is legally required to remove mold and fix the underlying moisture problem.

If you have found mold in your apartment, do not panic. Follow this step-by-step guide to assert your rights and get the problem fixed.

Step 1: Document Everything

 

Before you send a single email, gather evidence. If you end up in Housing Court or filing a complaint with the city, you will need proof.

  • Take Photos and Video: Get clear, well-lit photos of the mold. Use a coin or ruler in the shot to show the scale of the growth.

  • Log the Smell: If you can’t see the mold but can smell it, write down when you first noticed it and if it gets worse when it rains or when the heat is on.

  • Track Your Symptoms: If you or your family members are experiencing headaches, coughing, or allergy symptoms, keep a daily health log.

Step 2: Notify Your Landlord (In Writing!)

 

A phone call to the super is not enough. You need a paper trail.

Send a formal letter or email to your landlord and management company. In the letter, include:

  1. A description of the mold and where it is located.

  2. Photos of the damage.

  3. A request for inspection and remediation.

  4. Reference Local Law 55: Remind them that under NYC Local Law 55, they are required to investigate and remediate indoor allergen hazards like mold.

Tip: Send the letter via Certified Mail so you have proof of delivery. This stops them from claiming they “never got the message.”

Step 3: The Landlord’s Responsibility

 

Once notified, your landlord cannot just paint over the mold. Under NYC law, they must:

  • Fix the Source: Repair the leak, roof, or plumbing issue causing the moisture.

  • Remediate Safely: If the mold covers more than 10 square feet, they are required to hire a NYS Licensed Mold Assessor and a NYS Licensed Mold Remediator (that’s us!). They cannot use their regular handyman for large jobs.

  • Use Safe Work Practices: They must use containment (plastic sheeting) and HEPA vacuums to prevent spreading spores to your furniture.

Step 4: If They Ignore You, Call 311

 

If your landlord fails to act within a reasonable time, it is time to escalate.

  • Call 311 or file a complaint online with the NYC Department of Housing Preservation and Development (HPD).

  • HPD will send a code enforcement inspector to your apartment.

  • If the inspector finds mold, they will issue a Class B (Hazardous) or Class C (Immediately Hazardous) violation.

  • The landlord will then face fines and a strict deadline to hire a professional to fix the issue.

Can I Withhold Rent?

 

This is a risky strategy. While New York law does allow for rent withholding when the Warranty of Habitability is breached, you should never do this without consulting a tenant lawyer first.

If you simply stop paying, your landlord can sue you for non-payment. Instead, many tenants choose to file an “HP Action” in Housing Court. This forces the landlord to make repairs without putting you at risk of eviction.
