Manhatten-based digital content producers Zachary Bennett and Karen Nourse have been living in the suburbs of New York for more than six years without paying rent.
According to legal documents, the pair quit paying their $4,754.02 (NZ$6,766) monthly rent in 2010 and now owe $410,000 (NZ$583,000) in rent and electric charges, their landlord claims.
The couple, which have two children, say they have a right to live in the apartment rent-free as they are the only residents in a building, which is made up of commercial units and businesses, the New York Post reported.
Bennett and Nourse claim they don't have to pay rent as the building does not have a residential certificate of occupancy, according to court papers filed for a lawsuit.
The New York Post reported that before 2010 the pair had been paying rent. This was before the US Loft Law was expanded to protect "people whose apartments are in mostly commercial or industrial buildings."
