If you’re renting an apartment in New York City and mold keeps coming back, you’re not powerless — and you’re not stuck footing the bill. NYC has some of the strongest tenant-protection rules on mold in the country. Here’s a plain-English guide to your rights, what your landlord is legally required to do, and how to get it fixed properly.
Is your landlord responsible for mold in NYC?
In most cases, yes. Under NYC law, landlords are responsible for keeping apartments free of mold hazards and for fixing the underlying moisture problems that cause them — leaks, poor ventilation, and water intrusion. Mold is treated as a housing-maintenance issue, not something a tenant is expected to live with or clean up alone, especially when it stems from building conditions like a leaking roof, failing pipes, or a chronically damp wall.
Local Law 55: the Indoor Allergen Hazards law
NYC’s Local Law 55 requires landlords of buildings with three or more units to inspect for and fix indoor allergen hazards — including mold — at least once a year and whenever a tenant requests it. The law puts the duty on the owner to both remove the mold safely and correct the condition causing it. For larger jobs, it also requires the work to be done following safe-work practices so spores aren’t spread through the rest of the unit. If you have asthma or allergies, these protections are even stronger.
What to do, step by step
1. Report it in writing
Tell your landlord or management company about the mold in writing — email or text works — and keep a copy. A dated written record is what protects you later. Describe where it is and any leaks or dampness you’ve noticed.
2. Document everything
Take clear, dated photos of the mold and the moisture source. Note any health symptoms that started or worsened. This documentation matters if you ever need to escalate or if there’s a dispute about who pays.
3. Give a reasonable chance to fix it — then escalate
If the landlord doesn’t act, you can file a complaint with NYC’s Department of Housing Preservation and Development (HPD) by calling 311. HPD can inspect and issue a violation that legally requires the landlord to fix the problem.
4. Insist on proper remediation, not a paint-over
This is where many tenants get shortchanged. Painting over mold or wiping it with bleach doesn’t fix anything — it comes back within weeks because the moisture source is still there. Real remediation finds and stops the water, removes affected materials safely under containment, and verifies the air is clean afterward. If your landlord’s “fix” is just cosmetic, the problem isn’t solved.
Why independent inspection helps tenants
An independent mold inspection with air-quality testing gives you something powerful: written, lab-backed proof of what’s actually in your apartment. That report is hard to argue with, whether you’re pushing your landlord to act or documenting a hazard for HPD. It also identifies hidden moisture sources behind walls that a surface look would miss.
When bigger work is needed
If mold has spread into drywall, insulation, or behind walls, it needs professional mold removal and remediation with proper containment — and on larger jobs, clearance testing afterward to confirm it’s truly gone. Landlords are generally responsible for arranging and paying for this work when the mold results from building conditions.
