My post was in response to @MidiMagic, who said he’d be looking for a new single-story house, not to @cbmmm3, who is building a new structure.Not to mention, permits with building inspectors will happen.
This build is not being done without permits, guaranteed.
What you are referring to is electrical rough in and must be signed off. Then insulation R-13 minimum in walls, once those two inspections are completed then it is ok to drywall.
Trust me Ricky knows all this.
Electrical inspection depends on both the jurisdiction and the extent of modification. I recently had a kitchen remodel done, and the “inspection” only verified GFI function, and missed the fact that the electrician wired up the kitchen to the wrong circuit. Most DIY projects don’t require inspection.
