Reply to comment by TarondorIX in LPT: If you're buying a house still under construction, photograph everything before the sheetrock goes up. Knowing exactly where the pipes, wires, and ducts are may prove invaluable some day, and even if you never use them the next owner will appreciate it. by Needleroozer

There are likely construction drawings for any new construction. What there aren't and you probably want is asbuilt drawings showing any changes that happened. Those require each sub elec, hvac, plumbers, framers to keep red lines to give back to the engineer or architect and some one to then make all the corrections.

Not uncommon on large commercial jobs, would cost more than the average person would want to spend in residential construction. Also asbuilts usually aren't perfect even after all the time and money spent on them.
