While Berkeley does have a few examples of mid-rise buildings on a standard house-size 50' x 100' lot near campus where rents are high, the space taken up by the stairs and hallways makes this type inefficient. Single stair reform could change that. ordinaryhomes.blogspot.com/2023/09/poin... 14/
More likely, the 6-story density bonus buildings will be built on double lots - similar to how the building of Berkeley's 1960s mid-rise apartments also involved merging lots and replacing 2 or more houses. This size of building is currently being built near campus in Southside R-SMU zones. 15/
Wow I'd be thrilled if any of these density bonus examples are feasible and actually get built!
I think they are, as similar buildings are being built in Berkeley's commercial zones and R-3 and R-SMU zones high density residential zones.
