an identical one, which would be a huge waste and certainly dumb.
The tv show flip or flop with tarek and that gorgeous christina:) have epis odes where they buy property at auction. when a unpermitted space turns up they must remove the drywall from at least one side, inspect it, bring it u p to code, get it inspected by the building inspector then replace the drwa ll. some unpermitted stuff thats real junk gets demolished but thats the ex ception not the rule.
I highly recommend the show, christiana is easy on the eyes, they make big bucks, and the show is educational....
