You make a lot of good points but I see many instances where 13D/13R are misapplied IMHO, for economics purely. I often think if a building is hard to define then do it 13 and be done. Just my thinking, a lowly Sprinkler Designer, NICET Level 0.

The problem is the definitions have various meanings depending on region of the country, and building code under which your working, and yes even the building code official. East coast "Row House" Mid-west and West "Town house" or "Attached" dwelling units. Then enter the realtors with "Condos"!!! Just because it's a condo doesn't mean it can't be a Row or Town House. Condo doesn't exclude it from being a single family dwelling or home. We try to use common sense, but that assumes that everyone else has some. Very risky! If the separation wall meets the requirement for 0 lot line exposure, and each unit has its own individually metered utilities then they are single family homes and can be done 13D even if there are 100 of them in a row. If however they use a common water supply, or they don't meet the 0 lot line separation requirements they are 13R. And finally if the Arch. took and the AHJ allowed area increases, possibly even some setback variances or egress issues then this may very well become a 13 system. Height is it's own separate issue, except where it changes 13R to 13 automatically after 4 stories. The is nothing in 13D which would not allow a 6 story single family home. That's a building code or ordinance issue. Just as an example lets say you get a call from Harold Homeowner, and he wants a 13D fire sprinkler system in his 1860's Row house in Phila. or Boston, or Balt.or Richmond, where ever. There are 50 houses in his block, all with adjoining walls, usually 2 or 3 courses of unfired red brick.These brick walls extend to or through the roof. Each home has its own water and elect. meters. Can you do this home 13D? I say yes, and in this case the 0 lot line separation may not meet current code. No code or standard can meet every contingency, that's when experience and common sense need to be brought to the fore.
