Kol Peterson

I’m Kol Peterson.  I live in Portland, Oregon, one the leading cities in accessory dwelling unit development in the United States (~2800 total permits issued, with 615 ADU permits issued in 2016). Since building my own ADU, I’ve focused my energies on ADU advocacy, education, consulting, policy work, and entrepreneurship. I'm the organizer of the largest ADU tour in the country, and I'm the author of Backdoor Revolution: The Definitive Guide to ADU Development (scheduled to publish in January, 2018). In 2013, my wife and I also opened the Caravan-The Tiny House Hotel, the first tiny house hotel in the world.

Hi, I'm Thad Peterson, Kol's older (and much smarter) brother. I've got a background in video production and product marketing, and I've become quite the fan of ADUs through Kol's passion and knowledge of them.
