Owen If the townhouse units are separated with the appropriate walls by the local building code, then yes 13D is acceptable. Beware that sometimes builders call apartments "townhomes". Check the platting to see if they are all individual lots. As for the water supply arrangement you mention, that does not appear as one of the options in 13D A.6.2. However that is annex material. If the AHJ is willing to accept that arrangement, it meets the Chapter 6 requirement for an automatic water supply. The issue is who owns the water meter and the bill. Is there an association? We see a similar arrangement quite often here in Florida because the water purveyor is afraid of shutting off the sprinkler system when turning off water for non-payment. They provide a single tap and we install a single backflow and run underground and up into each townhome. Make sure that your AHJ finds this an acceptable arrangement. Pete

The definition on townhouse is a one-family dwelling constructed in attached groups of three or more units in which each unit extends from the foundation to the roof and has open space on at least two sides. Question: Does that mean if you had five attached townhouses you can install 13D system in each unit (each having a system riser with flow switch and bell), with all five townhouses being supplied off of one water meter (five risers being served by one meter) with the most remote/demanding unit being calculated per 13D, 2 heads flowing? In other words, each unit has it's own water meter supplying domestic needs, with a sixth, stand alone water meter, supplying all six townhouses 13D system? Yes or NO? Or Does that mean each unit, because they are attached but separated foundation to roof, can have a 13D system, each being supplied off its own domestic water meter?
