Developer's DescriptionBy SimplifyEmManage New York apartment buildings and communities.New York Apartment Lease Forms are used by New York property management companies that operate New York apartment buildings and communities. New York Apartment leases are typically custom designed because they need to include language that is specific to the shared spaces in the apartment building. If you are a landlord or property manager who is managing individual residential rentals (single family homes, duplexes, vacation homes), you may want to check out the residential lease instead.
