Baltimore, MD became the largest US city to pass a zero sq. ft. home fire sprinkler requirement in all residential properties. According to a press release issued by the Mayor's Office, dated June 24th, "Mayor Mayor Stephanie Rawlings-Blake joined Council President Bernard Jack Young, Councilwoman Mary Pat Clarke (District-14), Councilman Warren Branch (District-13) and Fire Chief James Clack to sign into law City Council Bill 10-0437, Residential Code - Automatic Fire Sprinkler Systems."
Residential fire sprinklers have been saving lives across Maryland since the early 1990's. There have been no reported fire deaths in fire sprinklered properties. More than half of Maryland’s municipalities and nine counties have adopted similar requirements for one and two-family homes. They have paved the way for others in the state to follow. Prince George’s County has been a model, and published a report demonstrating the positive impact that home fire sprinkler adoption has had on its community.
The Maryland Department of Housing and Community Development completed its adoption process of the 2009 IRC, requiring fire sprinklers in all new one- and two-family homes and townhomes, with an effective date of January 1, 2011, allowing local jurisdiction to adopt or modify the code. However, with this move, Baltimore takes the lead by requiring fire sprinkler in all new homes beginning July 1, 2010.
