Local Law 55 of 2018 becomes effective January 19, 2019 in all five boroughs of New York City, and requires owners of multi-dwelling rental housing to inspect these dwelling units for indoor allergen hazards. It further requires owners to maintain conditions in these housing units to ensure that common areas are free of indoor allergen hazards and conditions conducive to indoor allergen hazards, to prevent the occurrence of any such conditions, and to remediate all such conditions and underlying defects.

Landlords have additional obligations under the law, which include:

  • Perform annual inspections in each dwelling unit & common area of the building;
  • Provide an annual notice & New York City Department of Health & Mental Hygiene (DOHMH) pamphlet to prospective & current tenants at the time of lease renewal that informs the household of the owner’s obligation to do the following:

Under Local Law 55, some of the required work practices to remediate mold includes:

  • Investigate & correct any underlying defect, including moisture or leak conditions.
