Operative Text
a. The owner of a multiple dwelling shall cause an investigation to be made for indoor allergen hazards in all occupied dwelling units and in common areas as set forth on subdivision b of this section. b. Investigations shall be undertaken at least once a year and more often if necessary, such as when, in the exercise of reasonable care, an owner knows or should have known of a condition that is reasonably foreseeable to cause an indoor allergen hazard, or an occupant makes a complaint concerning a condition that is likely to cause an indoor allergen hazard or requests an inspection, or the department issues a notice of violation or orders the correction of a violation that is likely to cause an indoor allergen hazard. c. All leases offered to tenants or prospective tenants in such multiple dwellings shall contain a notice, conspicuously set forth therein, which advises tenants of the obligations of the owner and tenant as set forth in this section. Such notice shall be approved by the department, and shall be in English and in the covered languages set forth in section 8-1002*. The owner of such multiple dwelling shall provide the tenant or prospective tenant of such dwelling unit with the pamphlet developed by the department of health and mental hygiene pursuant to section 17-199.7 . Such pamphlet shall be made available in English and in the covered languages set forth in section 8-1002*. (L.L. 2018/055, 1/19/2018, eff. 1/19/2019) * Editor's note: Repealed.

Under N.Y.C. Admin. Code § 27-2017.2, owners of multiple dwellings are required to conduct annual investigations for indoor allergen hazards in all occupied units and common areas, and more frequently when certain conditions arise—such as a tenant complaint, a known hazardous condition, or a city-issued notice of violation. Leases must include a department-approved notice, in English and other covered languages, explaining both owner and tenant obligations under this section. Owners must also provide tenants with an informational pamphlet on indoor allergen hazards developed by the Department of Health and Mental Hygiene.

Operators of multiple dwellings subject to N.Y.C. Admin. Code § 27-2017.2 generally maintain a documented schedule of at least one allergen-hazard inspection per year for every occupied unit and common area, with additional inspections triggered by tenant complaints, observed conditions, or department notices of violation. Compliant operators ensure that all leases—including those offered to prospective tenants—contain the department-approved allergen-hazard notice in English and any other required covered languages. They also keep copies of the Department of Health and Mental Hygiene pamphlet on hand to distribute at lease signing, in all required languages.

Under N.Y.C. Admin. Code § 27-2017.2, tenants in multiple dwellings have the right to receive a lease that includes a notice about indoor allergen hazard obligations, as well as a city-developed pamphlet explaining those hazards. Tenants may trigger an additional inspection by making a complaint about a condition likely to cause an indoor allergen hazard, and the New York City Department of Housing Preservation and Development can issue notices of violation to owners who fail to comply. Tenants who believe their owner has not met these obligations may consider filing a complaint with the relevant city agency or reaching out to a local tenant-rights organization for general information about available options.
