But it does happen and failing to install is unconscionable.

How much does a fire sprinkler system cost?
The price of a fire sprinkler system varies based on the size and type of fire sprinklers you install. In general, here are the costs you can expect:
$1 to $2 per sprinklered square foot for new construction projects
$2 to $7 per sprinklered square foot for retrofitting existing homes and businesses
$2 to $4 per sprinklered square foot for retrofitting high-rise buildings
Up to $10 per sprinklered square foot for retrofitting historic buildings
