There is a law in GA that prohibits 'shared' kitchen space. One operator per kitchen. Here is a link to another forum where they discuss it and possible ways to deal with it.

Looks like your best bet would be to find a church that has not leased their kitchen to a caterer already and see if you could rent that from them.
