Ouch! tough fees. Looks like a great start, keep up the good work. Agree on the pex in the floor, used boilers show up reasonably when you start asking around. Just don't let on to the county you are planning heat. Had a much lesser fee here, but a totally crazy time at the zoning office, wrong guy was up when my turn came, it seems. Built mine with walls higher than norm and a steep roof pitch, came in just barely under the code height.... Loft went in after the final inspection. Good place to store stuff I thought I wanted at the time. In retrospect.... I have often head "no matter how big you build, it will be too small too soon."
