Background
In New York City, commercial office leases are negotiated privately between landlords and businesses. Rents are usually quoted as a yearly amount per square foot. Office space is not covered by rent stabilization or the residential rent laws that apply to apartments, so lease length, rent and terms are set by the deal itself and are often not made public.
