What is an illegal eviction in New York?
An illegal eviction in New York is any non-judicial removal: changing locks, shutting off utilities, removing the tenant's belongings, refusing to provide keys, or threatening with force. New York (and every US state) requires the landlord to use the judicial process (notice + court order + sheriff or marshal). Self-help is the most expensive landlord mistake: tenant possession is restored by court order, the landlord pays damages (often 2x or 3x rent), attorney fees, and may face criminal charges in extreme cases. The eviction process is fast enough (14 days for pay-or-quit under RPL 711(2), 30-60-90 tenure-based for non-renewal under RPL 226-c, then court within 14-30 days) that self-help is never justified on speed grounds.
