About "floor plans": NYC DOB does not publish architectural drawings online; the drawings live with the DOB borough office (viewable by appointment or FOIL request, job #340374598 is the most complete recent plan set) and with the owner/leaseholder. The site plan above is generated from the city's surveyed building footprints, which is the most accurate publicly available geometry.
