Requires owners of covered NYC housing to address indoor allergen hazards, including mold and pests, and the underlying conditions that support them.
New York City jurisdiction · Sources checked September 15, 2026. Law numbers repeat by year. These educational summaries are not legal advice or a complete compliance checklist. Later amendments, agency rules, building characteristics, and effective dates determine the requirements for a particular property. Use the linked City sources to confirm current obligations.
Why it matters
Moisture intrusion, plumbing leaks, and pest entry points may require building repairs as well as cleaning or treatment. Review current HPD requirements for inspections, notices, safe work practices, and qualified contractors where applicable. Repainting a stained wall does not demonstrate that the moisture source was corrected.
In practice
A project example
A capital plan pairs repairs to leaking plumbing with appropriate mold work and follow-up, rather than carrying only a cosmetic painting allowance.
