Friendly reminder that Eddie Lampert effectively drowned Sears Holdings (Sears & Kmart) in the bath tub. He single-handedly wiped out two major retailers, hundreds of smaller ones, and tens of thousands of jobs in one of the most successful corporate raids ever executed.
Depending on what kind, I have the room to add as many as 3, but the problem here is city restrictions limit them to BACK yards only, not front yards. :( I have no back yard, it's ALL front yard.
So your mailbox and front door just need put on the other side, pave a little path around so it’s accessible by mail carriers and now you have a colossal back yard but no front yard.
Redefine your house as the ADU and the new unit as the house!

(It probably won't work because of rules saying that ADUs must have less square footage than the house and that the total must not exceed some floor area ratio for the whole lot, but it's a fun thought.)
There would probably be some nightmare with changing the address as well because the new unit(s) would be between the existing house and the street where the address is. Apparently your street address is determined by where your front door faces.
