Re: When do you start over?
Some years ago in a nearby town a two-story commercial building was "remodeled." Everything from the second floor up -- walls, ceiling, roof structure -- was torn down. The second floor was then supported with cribbing and everything underneath -- walls, slab, foundation, footings -- was removed. After sitting there for several months with nothing but the second floor up in the air on cribbing due to the need to address some environmental issues (leaking underground fuel storage tank), the "remodeling" continued with new foundation, walls, and roof structure, but of course keeping the original second-floor floor structure.
But since the second floor was kept and the footprint of the building didn't change, it qualified as a "remodel" which meant that the owners avoided having meeting new setback requirements and didn't have to pay impact fees for "new" development.
Maybe you could do something similar?
