So answering my own question, NFPA Research Foundation updated the report in 2013.
Checkioutpeople: cost has actually dropped. Mean $1.61 (2008) $1.35 (2013) Median $1.42 (2008) $1.22 (2013) From: Sprinklerforum [mailto:[email protected]] On Behalf Of Steve Leyton Sent: Tuesday, November 14, 2017 7:57 AM To: [email protected] Subject: Average cost for 13D systems NFPARF published an estimate of average cost for a residential (one/two family) sprinkler system in 2009 in the run-up to the IRC vote that year. I think the number was $1.61; does anyone know if they or HFSC have published an updated cost estimate recently? [Steve Signature (3)]
