KRK,

Fire safety is regulated with the building code for new buildings.  However the bldg code does not require mandatory upgrades in older buildings with each code cycle.  Only a few select items are made mandatory, usually changes in the electrical code.

Local governments which adopt the various bldg codes with legislation can require retrofits.  The Council is now considering that move.

Local governments can also remove safety items from bldg code adoption.  The Council removed the requirement for sprinklers in single family residences that is included in the 2012 International Building Code which will become our newest code in the near future.
