@gkomo - Man that is great you are doing all of that and yes having an in with the contractor is huge. I know its more money but I would hire a 3rd party inspector before they start covering thing up (wall board, cabinets, flooring, etc.) so that pictures can be taken and a report done so they can correct any deficiencies prior to covering it up as that is expensive.
@Noobz347 - typically they inspect form boards for pouring concrete which typically has the rebar in it, plumbing rough in, electrical rough in, then plumbing final, and electrical final. Most say that you need to build to the 2018 building code but the vast majority of that is left to the trades to honorably do correctly.
In my world we have inspectors on the job a week before it starts until it's finished and the red line drawings are turned in. We have qualification testing for all the work, all the welding is 100% non-destructively tested (x-ray, ultrasonic, vacuum box, mag particle, etc), all of the welding is inspected including the welding rig function, soil compaction testing, concrete testing, pipe pressure testing, coating installation inspection, and then there is all the electrical and controls inspection.
I realize you cannot afford to inspect everything on a home build or remodel as we could not afford that but I know how city and count inspectors do things and its almost laughable in some places.
Anyhow, I would seriously consider having that same 3rd party inspector you were going to have look things over after you move in to do some inspecting now.
