How to set new addresses on a multifamily??

[Sylvia Santelli]

Anyone have experience doing this? 

I just purchased a 4-plex, but the previous owner does not have separate addresses for each unit.

For example, I pushed 123 MainStreet and I want each unit to be represented separately, 123 MainStreet Unit A.

Do I need to do anything official with the post office or city? Or do I just put the mailboxes and numbers on each unit door?

I can answer for San Antonio, although it May be different in Dallas.  If it is in fact zoned multi family then the city services will have separate addresses because of the utilities and billing. In that case they will have unit numbers. If not, you can work with the postal system to assign unit numbers.
