Home Sprinkler Law

Citizens Count Editor

Note: This write-up was last updated in October 2015. 

In 2009 the Building Code Review Board passed a measure calling for sprinkler systems in every newly constructed single- and two-family home and town house, starting in 2012.  In 2011 the Republican-controlled House and Senate then passed two bills that prohibit communities from mandating sprinklers in homes: SB 91 and HB 109.

A 2008 study from the National Fire Protection Association found that the average cost of a home sprinkler system was $1.61 per square foot, roughly $3,200 for a 2,000 square foot home.


"For" Position

By Citizens Count Editor

State Fire Marshal William Degnan argues that sprinkler systems save lives.

At least two states, California and New Jersey, have sprinkler mandates.

"Against" Position

By Citizens Count Editor

Opponents of sprinkler requirements claim that the requirements are too expensive for homeowners, and represent an overreach of state government. They also cite the cost-effectiveness of smoke detectors.

Thank you for you information on sprinkler mandates from small town planning boards. I believe these were put in place to discourage contractors from building developments in our town, because smaller subdivisions do not require sprinkler system requirements built into the deed as mandatory. We were subdividing only four lots (considered a major) and were told we must mandate sprinkler system requirements built into deed. Thank you for your information.
