When extending the lease, the tenant may also find that the landlord has “reaculated” the surface and now claims that it is much larger. A well-known Manhattan landlord told a tenant whose tenant`s surface area I know has increased by 20%. It also demanded a higher rent per square foot – a double shot. A doctor in Suffolk County, New York, has signed an eight-year lease for offices. Less than a year later, the building burned down. The landlord complained about another rent and won, although he was not forced to repair the building. New York law would have protected the doctor from this kind of thing, but the lease contained a clause that provides that the rent does not decrease and that his liability under the lease persists even if a victim destroys the building.
