Auached g-3 <br />with more than ~16 dweliihg uhits :4r <br /> <br />Here are some examples: <br /> <br />Multi-flintily home built to the International Building Code as an R-2. Not open on ~o sides. Row <br />houses back to back. <br /> <br />156' <br /> <br />These 14 single level units equal 8,580 square feet and are attached. These would require a 13R <br />system (R = residential). This system has one main water line that normally leads through the <br />center of the structure so that branch lines can feed offof it into the residence. Because majority of <br />these homes are back to back, they do not have two sides, therefore requiring them to be built under <br />the IBC. They are not built the same as a single family home. These systems would follow NFPA <br />13 R that would require a fire department connection and a horn and strobe to alert others of a <br />system activation. It would also need to be monitored if there are a total of 20 sprinkler heads or <br />11101'13. <br /> <br />Take Ihe same amount of homes, and give them access to two sides, front and back, and they can <br />now be built to the IRC and called a single family home. A fire sprinkler system (13D) would be <br />required if the total gross area of these is greater than 8,500 Sq. Ft. These systems run off the <br />domestic water system. They require no maintenance and need not be monitored by an alarm <br />company. If these were ATTACHED, three stories or greater and less than 8,500 Sq. Ft. they <br />wou Id be required to be sprinkled as well. <br /> <br />ALLEY <br /> <br />2 <br /> <br /> <br />
