Katt Williams: Stay Out or Else! Banned for Fighting Kid

Pretty soon Katt Williams won't be able to leave his own bedroom without getting arrested -- we've learned he could be locked up if he sets foot on a bunch of properties in Georgia.

A rep for the Gainesville Housing Authority tells TMZ ... Katt's been banned from all 14 of their housing complexes around town because of that brawl he had with a teenager. That went down at the Melrose Apartments -- a property managed by G.H.A.

Law enforcement sources confirm Katt will be arrested if he returns to any of the properties.
