Right now, many adults in LA have to share a single family home with several other adults, living like college roommates, because otherwise they can’t afford rent. Even just the european solution of mixing rowhouses and 3-5 story apartment buildings would fix that. In fact, it would significantly increase density and reduce cost, in turn reducing commute times for many people. Even an apartment can be built well enough that you don't have to worry about sharing walls with neighbors. My neighbor is regularly watching movies at THX reference volume, and so am I, and neither of us can hear each others' audio. With land value as high as it is in LA, it's worth spending money on improving the quality of construction, so people can share walls with their neighbors without any of the negatives usually associated with it.
