The American Tiny House Association mission is to promote the tiny house as a viable, formally acceptable dwelling option for a wide variety of people.
Our goal is to support tiny house enthusiasts who are seeking creative and affordable housing as part of a more sustainable and self-reliant lifestyle.
We seek to represent the needs and values of the tiny house community:
– to gather and provide information regarding the building of and dwelling in tiny houses
– to promote a healthy social and political environment conducive to tiny house building and dwelling
– to educate members regarding tiny house quality and safety, and
– to network and cooperate with related government agencies, educational institutions, development organizations, and private industry to address these stated purposes.
