New York City’s fire safety ordinance for high-rise office buildings (Local Law 5) requires owners to make substantial physical and operational modifications to their buildings. Installation of elevator recall buttons fire alarm and communications equip ment and the development of fire safety lans are some of the requirements which apply to all new buildings and the 820 existing buildings which are over 100 feet in height. The most expensive task facing New York City building owners, by far, is Phase II of the law which requires either complete sprinklerization of the building, or alternatively, floor compartmentation and pressurization of all interior stairwells.
