Plain English

New York Multiple Dwelling Law § 12 establishes three categories of prohibited uses for multiple dwellings and their lots. First, the premises may not be used for prostitution or assignation in any form. Second, most livestock and poultry—including horses, cows, swine, chickens, and most pigeons—are barred from the property unless local law expressly permits them. Third, combustible or otherwise dangerous materials may not be kept or stored on the premises without a permit issued under local law or, where no local law exists, under fire department rules.

For Property Managers

Under N.Y. Mult. Dwell. Law § 12, compliant operators of multiple dwellings generally ensure that no part of the building or lot is used for prostitution or assignation, that no prohibited animals are kept on the premises without the backing of a local ordinance, and that any storage of combustible or hazardous materials is covered by a valid permit from the appropriate local authority or fire department. Property managers typically include lease provisions that mirror these statutory prohibitions and conduct periodic inspections to confirm compliance. Violations of § 12 can expose an owner to enforcement action by local housing or fire authorities.

For Tenants

N.Y. Mult. Dwell. Law § 12 gives tenants a basis to raise concerns when a multiple dwelling or its lot is being used in ways the statute prohibits—such as the storage of hazardous materials without a permit or the keeping of banned animals on the premises. Tenants who believe a violation exists may report the condition to local housing code enforcement, the fire department, or a local rent board if one has jurisdiction. Tenant-rights organizations can help residents understand how § 12 applies to conditions in their building and what complaint or defense options may be available.
