There is a thing called the United States building codes. This are the basic construction standards (must do it this way). In addition, many localities add requirements based on their area problems - California has earthquake requirements, Florida has hurricane requirements, etc. I would suggest that you identify were you are and then ask a series of basic questions – foundation, framing, electrical, plumbing, out building, etc. After a few questions & answers, you will begin to learn what you must learn.
