I agree in principle with the definitions CAR found but am looking at this issue thru the lens of local bureaucrats who will “categorize” the project according to city/county supervision level needed, the presence or absence of utilities, hookups and paved encroachments and thus the fees that will be imposed. My post above represents how a local jurisdiction will see the project and in reality, is how the “system” here works. Like it or not, it’s in the homeowner’s best interest to leave all or a portion of a wall standing and meters intact before beginning construction on their “complete remodel.”
After completion of a “complete-remodel,” the SD County Assessor will still report the original build date as the age of the property, even with all new systems, three new exterior walls and all new interior. This year will reflect the age as shown in a future listing (i.e. 1953). In the comments, section, the agent can state, “permitted complete remodel with all new systems signed off on 2003 – plans available,” or whatever applies.
Rustico, IMO, you have built a “custom mini-estate” for your family :=]
