> there's also a section that is engineered/calculated which is what makes the code very flexible

That section of the code requires a PE stamp.

PEs don't work on residential houses unless it's a mansion or a cookie-cutter subdivision.

In certain markets/jurisdictions it's standard/common to have multiple PEs stamp multiple different parts of the plans. For single family homes. Probably the lowest hanging fruit is energy calcs. For instance getting a PE to do title 24 calcs and stamp a plan is a couple hundred bucks. For $200 you open up a LOT of flexibility in design, materials, etc. Everything from window/door sizes, styles and locations to HVAC duct type.
