According to the Fire Protection Research Organization's 2009 Fire Sprinkler Cost Assessment, sprinkler installation costs homebuilders $0.38-$3.66 per sprinklered square foot, with an average cost of $1.61 per sprinklered square foot. For an average 2,200-square-foot home, expect to pay about $3,542.
Using a larger sample size, the current study attempts to gain a better understanding of the impact of sprinkler ordinances on home fire sprinkler system cost and other factors that affect system cost. The current study examines 51 homes in 17 communities; the 2008 study examined 30 homes in 10 communities. In the 2013 update, the average cost per sprinklered square foot was $1.35. In the 2008 report, the average cost per sprinklered square foot was $1.61.
