Not wanting to get involved with the Code Folks hurts you more than them. Get a good site drawing showing all buildings, utility service locations. Add your proposed structure and make an appointment with a code officer. Yes, they can be the hardest of axxes but I’ve found them to be helpful face to face and actually appreciative that you take the time to ask. I’m of the opinion that it can make your site inspections on work done easier having them believing that you care to do it correctly.
