In fact, the permit process requires stamped engineered drawings in most states…NY and Ct for sure…in addition to naming licensed electricians, plumbers etc on the permit. The permit will also identify pool enclosure regulations that must appear on drawings.
Many towns also require approved grading and drainage plans as well.
I think your biggest challenge is with the health department; if they see something new they may really stumble you through the permit process. You may have to become an educator for these folks to help move your project along.
