So Ryan and Adam Routh have a company building tiny movable houses to allow buyers to skirt the need for permitting in HI. All responsibility for pissing off your neighbors with your little trashy house on wheels is the buyers. It figures that Ryan was a Bernie Sanders supporter.

"The Hawaiian Islands face unique challenges; with land cost at a premium, cost of shipping supplies, and a complex and overloaded permitting process, any space becomes extremely expensive. The Camp Box vision is to try and help our neighbors and friends with an affordable option to provide that needed comfortable space. Everyone should be able to have their own private spot on the island and know they are worthy, worthwhile and belong as a part of the community. Using standard economical, fast and efficient construction techniques and materials we can produce solutions to our own problems right here on the island. We do not need impractical imported solutions.

Camp Box offers an extremely efficient design that is a mobile and towable unit, so that owners will always have the flexibility relocate or tow their unit wherever needed. As a mobile unit it is not permanent and with 16 ft units are less than 120 square feet, they stay under building code requirements to avoid the lengthy building permit process, if someone wishes to make it a permanent accessory structure."
