Owen, It comes down to a building code issue. I recently completed a project such as you describe. Initially, it was "ruled" as 13D by the fire department. Then the building officials indicated that the architect had taken several sprinkler exceptions such as height, access road width, etc. These variances bumped the system from 13D to 13R. I'd recommend making some phone calls.

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?
