Kol Peterson

Hi, I’m Kol Peterson, and I’ve been obsessed with ADUs for the last decade or so. I live in Portland, Oregon, which is the leader of accessory dwelling unit development in the United States (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 late 2017). 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.
