If you own or manage a residential building in New York City with three or more units, you are likely familiar with the Asthma-Free Housing Act, better known as Local Law 55.
As we move through 2026, the City’s Department of Housing Preservation and Development (HPD) has ramped up enforcement. What was once considered a “suggestion” by some is now a primary source of heavy fines and litigation. Local Law 55 requires landlords to proactively keep their buildings free from “indoor allergen hazards”—specifically mold and pests.
Here is what you need to know to stay compliant and protect your investment this year.
The Core Requirements: Proactive vs. Reactive
Most NYC building regulations are reactive—you fix a problem when a tenant calls 311. Local Law 55 is different. It requires proactive annual action.
-
Annual Inspections: Landlords must conduct an annual inspection for mold and pests in all covered units.
-
The “Notice to Tenant”: Every year, you must provide tenants with a pamphlet (approved by the HPD) outlining the landlord’s and tenant’s responsibilities regarding indoor allergens.
-
Lease Riders: You must include a specific Local Law 55 notice in all new leases and lease renewals.
Identifying “Hazardous” Mold
Under Local Law 55, any visible mold in an indoor environment is considered a violation. However, the law distinguishes between small patches and large-scale infestations:
-
Class B Violation: Mold covering less than 10 square feet in a single room.
-
Class C Violation: Mold covering more than 10 square feet or mold found in multiple areas of the same unit.
Class C violations are “immediately hazardous” and can lead to daily fines if not corrected within a very tight window (usually 21 days).
The 2026 Standard for Remediation
You cannot simply paint over mold. To “clear” a Local Law 55 violation or satisfy an annual inspection, the remediation must follow specific work practices:
-
Identify the Source: You must fix the underlying moisture issue (e.g., a pipe leak, roof leak, or poor ventilation).
-
Professional Removal: For any area over 10 square feet, New York State law requires a licensed Mold Remediation Contractor.
-
HEPA Vacuuming: The area must be cleaned using HEPA-filtered vacuums to ensure spores aren’t redistributed throughout the apartment.
-
No Bleach: HPD guidelines advise against the use of bleach on porous surfaces; instead, antimicrobial cleaners and physical removal of contaminated materials (like drywall) are required.
Why Compliance is Urgent in 2026
HPD is increasingly using data-driven enforcement. If a building has a history of leaks or multiple 311 complaints, it may be flagged for a “comprehensive” inspection.
Furthermore, failure to comply with Local Law 55 is now frequently used by tenants in Housing Court as a defense in non-payment cases, citing a “breach of the warranty of habitability.” Keeping your annual inspections up to date is your best legal defense.
