It's generally agreed that five stories is about the limit before a broken elevator makes the building basically uninhabitable. That is the point in which you can expect people with disabilities and people living at the top to be the only people using the elevator most of the time.
obviously the solution is walkable 3d cities. every 5th floor have small streets connecting buildings, every 10 floors medium, every 20 floors "highways" but for feet. individual elevators for the 5 floor blocks too. Expand the neighborhood block into a cube

Also more than 5 stories and everyone living there is a stranger instead of a neighbor you can know and trust
