The most basic and obvious safety related practice would seem an OC permit.

To me, this means the place has been looked at, considered finished, or finished enough to be habitable without incident.
I am being very liberal here and not 'splitting hairs' lest i entertain beuracratic opposition on the cost of this basic function.

Nope, i'll keep it simple heat, water,lights and some sort of 'contained' enviorment (i.e.-doors, windows..) to a finished and habitable degree.

My question is, how many states/countries actually have an OC process ?
