Here large apartment complexes get door delivery. For single family, unless resident is certifiably limited in mobility delivery is to communal array of postal boxes. Alternating 2 and 3 days a week. Running through a building is not too inefficient. Delivering between them is.

That still seems like a big waste of time. Having a postal worker walk door to door throughout a large building takes way longer than having them fill up the mailboxes in a single mailroom on the ground floor. I wouldn’t be surprised if it took ten times as many postal workers to deliver to apartment doors instead of mailrooms.
