Random Question About Houses and Streets

Alt. Hed.: Things One Might Wonder As One Walks In The Morning.

What — or who — determines how many digits are in the number of the addresses of houses on a street? Can any smart FrontBurnervian (is there any other kind?) tell me? Do developers get to decide if it’s going to be, say, 1313 Mockingbird Lane versus 131 Mockingbird Lane versus 13131? Does the city? And why are some houses four numbers off from their neighbor, some six, some whatever? If we don’t find out the answer today, I guess we’ll have to wait until Friday.
