County-wide mandates for life-saving sprinklers do not result in reduced housing supplies, compared to counties without sprinkler requirements
July 15, 2009 — The results of a new study conducted for the National Fire Protection Association (NFPA) concluded that the presence of sprinkler ordinances has no negative impact on the number of homes being built.
Conducted by Newport Partners, Comparative Analysis of Housing Cost and Supply Impacts of Sprinkler Ordinances at the Community Level (PDF, 416 KB) compared residential construction in four counties; Montgomery County, Maryland, was paired with Fairfax County, Virginia, and Prince George's County was paired with Anne Arundel County, both located in Maryland. Montgomery County and Prince George's County have sprinkler requirements; Fairfax County and Anne Arundel County do not. The selected areas, all developmentally mature, cover a wide geographic area and contain a variety of housing stock and income levels, making them prime for comparing municipalities with and without sprinkler ordinances in place.
“This study clearly demonstrates that home fire sprinkler requirements do not impede housing development starts,” says Jim Shannon, NFPA president. “This report is another point to make the case for enacting life-saving sprinkler requirements in local communities. “
Sprinkler ordinances were enacted in Montgomery and Prince George’s Counties in several stages, beginning in the late 1980s, but never in Fairfax County. Anne Arundel County adopted a requirement for single-family detached residences this year; this study looked at Anne Arundel County housing starts prior to the ordinance. No reduction in the number of single-family homes built in either Montgomery County or Prince George’s County accompanied the enactment of ordinances, compared to the other two counties in the study that do not have sprinkler ordinances. Rather, both Montgomery and Prince George’ counties saw larger relative increases in construction in the year after the ordinances went into effect, compared to the other two counties.
Data for the analysis included annual single-family building permits, surveys of housing and households, local documents and news reports released before and after adoption of residential sprinkler requirements, as well as reviews of other housing regulations. Interviews with key builders, trade association staff and local government officials were also conducted.
In interviews, builders and staff of the Maryland-National Capital Building Industry Association (MNCBIA)all indicated that the sprinkler requirements did not significantly affect the volume, character or price of the construction of new homes. According to the report, "None of the statistical or interview information demonstrated that the requirements led to reduced housing supply."
All model safety codes now require the use of fire sprinklers in new one- and two-family homes. These requirements offer the highest level of safety to protect people and property. To review the complete finding from this report, please visit the Fire Sprinkler Initiative’s Web site.
