We are located in a county in FL that requires a permit for anything to include a portable buildings.  We came from a county in TN that if you built a pole barn for agricultural purposes i.e storing a tractor along with your MH no permit needed....go figure.  Having said this, in your situation, your county may have all together different guidelines.   Have you looked at one of those Versatube RV carports (https://www.versatube.com/)?  Home Depot may be able to get the size you need.
