What is the definition of a “turnover” in the context of the obligations of a landlord to correct a lead paint hazard in a New York City apartment?

A “turnover” means the occupancy of a dwelling unit after the termination of a tenancy upon the vacatur by a tenant after the effective date of Local Law #1 of 2004 to wit: August 2, 2004. What this means is that any new tenant who commenced his/her tenancy after August 2, 2004 is afforded the protections granted by Local Law #1 and a landlord has the corresponding duties with respect to lead abatement as set forth in the law to this/these new tenant(s) before they move in.
