Coincidentally , my AHJ was explaining an 'open permit' to me today HotOne.

It's for one of those jobs that never really get done, but need checks along the way. Case in point is an old 9 unit apt/commercial building in town we've systematically weeded out the K&T on.

Because we really never know just how much we're going to do, until we start investigating, we simply have a running list that we 'check in' with our AHJ , who comes out when he deems it necessary
