Jenny, After finding a location and setting that you can see your future home. My recommendation would be to bring in an experience builder or remodeler that has experience to the area. Each municipality, or governing body, has there own rules and regulations that must be followed. I have had many experience's with both local and county governing bodies. everything is not black and white, much of it is very Gray. Have a experienced team to help in the process and could ultimately save you money and time.
