The way most houses are built in the US is pretty idiot proof after the foundation is done. You follow the (rather basic and simple) rules of how you do the framing, and as long as you don't exceed the limits laid out by typical zoning laws for suburban houses, nothing is going to collapse.

There is expertise and education required to set the foundation in a safe and durable way, and there is the same required to do heating, cooling, wiring, etc, but the majority of how they are built is intentionally done so you can hire people who you can barely speak English and treat them like shit and they will still give you good enough results.
