The triple-decker three family is great in that there are windows on four sides and stairs in front and back. There are also double triple-deckers (six units)- the stairs are shared by two triple-deckers sharing a common wall. Most of these are side by side, but in Worcester, there are also front / back ones like this (134 Elm St.): https://www.google.com/maps/@42.2661816,-71.8159232,3a,75y,189.92h,90.88t/data=!3m6!1e1!3m4!1sZZa7osu9oTqvDFT0z7ew7A!2e0!7i16384!8i8192?entry=ttu https://www.google.com/maps/@42.2661816,-71.8159232,3a,75y,1... or with turrets: https://www.google.com/maps/@42.2662587,-71.8167573,3a,75y,206.97h,92.86t/data=!3m6!1e1!3m4!1sBCLUtuf0OnJRq7Xb1t4FkA!2e0!7i16384!8i8192?entry=ttu https://www.google.com/maps/@42.2662587,-71.8167573,3a,75y,2... The stairs are definitely shared in the side-by-side ones, not sure how it works in these. So I used to rent in a 10-unit five story brick and wood building with front and back stairs, so I question a bit that the two stair requirement is such a big deal. This building had a central open area, and an old (broken) cage style elevator.
