N.Y. Gen. Mun. Law § 970-J
The legislative body shall prepare a feasible plan for relocation of all families and persons to be temporarily or permanently displaced from housing facilities in the project area. The legislative body shall insure that such plan for the relocation of families or single persons to be displaced by a project shall provide that no person or family of low and moderate income shall be displaced unless and until there is suitable housing available and ready for occupancy by such displaced person or family at rents comparable to those paid at the time of their displacement. Such housing shall be suitable to the needs of such displaced person or family including, but not limited to, access to work, adequate space and other financial considerations and such housing must be decent, safe, sanitary, and otherwise standard dwellings. The agency shall not displace such person or family until such housing is available and ready for occupancy.
