First, find out what you can get away with. Go to the local office and get that sorted out. If not, you may end up on the wrong side of the deal and have to tear it down. Since I don't know the situation with your residency follow that advice accordingly.....
Secondly, it is much more affordable (or it was) to have a building put up and assembled by one company. I am sure prices are not the same but about 7 years ago a 32x32x12 installed and ready for use (and done in a day with exceptional quality) was about 11,000.00. I had the pad poured and ready to go. I can stress enough about how well it went and was finished in a day.... Carolina Carports.
The downside is noise, climate, and moisture. And can all be cured with good insulation. And you want to do that before anything is done inside. What that cost I do not know but looking back I made that mistake of not finishing the dealin regards to insulation. And make sure you get the right structure for your area. The companies that sell them know your area and will suggest the proper building accordingly. If they don't either ask or call another company that has the info....
