Hands down the number one question that I get asked when it comes to tiny houses is:
"What are the codes in my area for building tiny houses?"
In talking with other folks in the tiny house community this question is popular across the board.
Now, I can't speak for anyone else, but I wanted to take a moment to address this question because it is the one question that I can't answer.
Building codes are, in general, implemented and enforced at a municipal level. This can mean that the city has one set of codes but the rest of the county that city is in works with an entirely different set of standards. This country is vast and the codes in rural Michigan are going to be quite different than those of the city of Portland, Oregon.
There is really only one way to learn about the codes in your area and that is to talk to the local government. But be prepared. Tiny houses are still a thing of mystery to most people. Even though we understand and value the concepts of building small homes doesn't mean that it will be embraced by the code enforcement office.
One fantastic resource to consider if you are interested in building and living in a tiny house is "Cracking the Code" an eBook by Ryan Mitchell which is available at his website, The Tiny Life.
I really wish I had a magic answer for all the people who ask me about zoning or building codes. My only suggestion is to chose the general area where you want to live and do your research about what is possible. Sometimes rural areas have fewer restrictions but this isn't a universal truth. Other times you may fly under the radar by putting your home on wheels, but you'll need to be prepared to deal with the consequences if you get caught.
It does make me happy to hear from so many people interested in moving forward with changing their lives. Keep up the good work and learn all you can about how to make it happen for you!
