That gets a lot trickier. One meter will need to feed a 480V panelboard that feeds a transformer that feeds a 120V panelboard to deal with the Owner's 480V and 120V house power.
The other meters will feed the tenants who will likely want strictly 120/208V for their stores. Most POCO rules don't want a transformer on their side of the meter, so each Tenant will end up with a transformer...
If you can't change the Owner's mind about the 480V, see if you can get the POCO to give you (2) Service drops...480V and 120V.
That way there are no transformers to mess up the layouts, since most Tenants are very defensive about losing square footage for anything that doesn't add to their bottom line.
