Illegal Transient Conversion (§ 28-210.3)
NYC Admin. Code § 28-210.3
NYC Administrative Code § 28-210.3 makes it unlawful for any person or entity who owns or occupies a multiple dwelling or dwelling unit classified for permanent residence purposes (a Class A multiple dwelling, occupancy group J-2 or R-2) to use, offer, or permit its use for other than permanent residence purposes, and such a conversion in use can occur even if no physical changes are made to the unit. It is a primary Department of Buildings provision used to cite illegal short-term/transient rentals, and under the Administrative Code's violation-classification rules a violation involving more than one dwelling unit, or a second or subsequent violation, is classified as immediately hazardous.
