www.earthship.com/codes-regulations-laws What is the purpose of building permits and codes? What permits do I need to build an Earthship? Are there any places where Earthships are prohibited?

How are you fighting codes in overly regulated areas? If I want to build the latest Earthship model, what is my first step?
