Any conviction of a tenant for violation of this code which:
(1) Results from wilful or grossly negligent conduct and causes substantial damage to the dwelling units; or
(2) Results from repeated or continued conduct which causes damage to the dwelling unit or substantially interferes with the comfort or safety of another person; or
(3) Consists of an unreasonable refusal to afford access to the dwelling unit to the owner or his or her agent or employee for the purpose of making repairs or improvements required by this code, shall constitute grounds for summary proceedings by the owner to recover possession of such dwelling unit from the tenant.
a. Legislative declaration. The council hereby finds that the enforcement of covenants contained in multiple dwelling leases which prohibit the harboring of household pets has led to widespread abuses by building owners or their agents, who knowing that a tenant has a pet for an extended period of time, seek to evict the tenant and/or his or her pet often for reasons unrelated to the creation of a nuisance. Because household pets are kept for reasons of safety and companionship and under the existence of a continuing housing emergency it is necessary to protect pet owners from retaliatory eviction and to safeguard the health, safety and welfare of tenants who harbor pets under the circumstances provided herein, it is hereby found that the enactment of the provisions of this section is necessary to prevent potential hardship and dislocation of tenants within this city.
b. Where a tenant in a multiple dwelling openly and notoriously for a period of three months or more following taking possession of a unit, harbors or has harbored a household pet or pets, the harboring of which is not prohibited by the multiple dwelling law, the housing maintenance or the health codes of the city of New York or any other applicable law, and the owner or his or her agent has knowledge of this fact, and such owner fails within this three month period to commence a summary proceeding or action to enforce a lease provision prohibiting the keeping of such household pets, such lease provision shall be deemed waived.
c. It shall be unlawful for an owner or his or her agent, by express terms or otherwise, to restrict a tenant's rights as provided in this section. Any such restriction shall be unenforceable and deemed void as against public policy.
d. The waiver provision of this section shall not apply where the harboring of a household pet causes damage to the subject premise, creates a nuisance or interferes substantially with the health, safety or welfare of other tenants or occupants of the same or adjacent building or structure.
e. The New York city housing authority shall be exempt from the provisions of this section.
