Residential Sprinkler
• Residential fire sprinklers are
mandated in all residential
buildings by the International
Building Code and the
International Residential Code.
• Many states have adopted all or
part of these requirements
including California, Maryland,
Pennsylvania, New Hampshire,
and Wisconsin
• Fire sprinklers are regulated by
either NPFA 13D or IRC Section
P2904.
Purpose of NFPA 13D and P2904
• The purpose of NFPA 13D
and IRC Section P2904 is
to:
– Provide protection of a
home with a sprinkler
system
– Assist in the escape from a
fire (within 10 minutes)
– Save lives
– Low cost
• Secondary benefit:
– Protect property
