Just 252 square feet, this tiny house in Royalston, Massachusetts is fully permitted and legal, and was built using modified Tumbleweed “Bodega” plans. It’s on a permanent foundation and was completed in October 2013.
According to owner/builder Chris Haynes, the code in his area requires one room that is at least 150 square feet, and while the living room area was listed as only 120 square feet in the plans, when combined with the kitchen, Chris was able to achieve the 150 square feet minimum. He also had to add a back door to the plan, and he discusses the allowed width of that door. Chris praises the building inspectors in Royalston.
Derek “Deek” Diedricksen, of HGTV/DIY interviews owner/builder Chris Haynes, and the conversation on meeting the code starts at the 1:10 minute mark in the video.
