text: If fire sprinklers aren’t explicitly mandated, the codes often make it highly advantageous to install them as an optional system by allowing for less expensive construction types (and thus less expensive building materials), larger floor area limitations, longer egress paths, and fewer requirements for fire-rated construction in structures protected by fire sprinklers, reducing the total building cost.
