The difference is that the sprinkler requirement can often be avoided on existing buildings when renovated, depending on the level of renovations and the jurisdiction requirements. AHJs (and legislators) know sprinklers cost a lot to retrofit. In new construction just part of the cost. | |

However, a Sprinklers are installed at 10 or 20 times the cost of a smoke detector system, it must be certified each year, and is inflexible for future remodeling without additional design and remodeling cots. Sprinklers work on the basis of a raging fire getting hot enough to melt the retainer on a sprinkler head. Whereas a smoke detector will pick up products of combustion long before you have a fire raging in the building. Early detection allows you to respond to the problem early. | |

| Jan 15, 2021 at 21:40 | comment | added | ThreePhaseEel | My understanding (from reading HO policies) is that even at the dwelling level, there are overall savings offered for sprinklering, and the savings are more significant in commercial work. (The costs of prompt remediation of water damage are minimal compared to fire/smoke damage remediation) | |

They do little to nothing to protect property unless someone is at the building awake and competent to deal with it or if (typically in large commercial buildings but not individuals homes) centrally monitored. Sprinklers can save a building - and the neighboring buildings - even if nobody is there. | |
