I think that the tiny house movement is a good thing , especially if it involves solar power, but for it to do well we are going to have to change our culture. When I was in grad school at UCCS back in the early 80's there was a consensus that houses should be smaller and use less resources, but what actually happened? Houses got bigger, used more resources, and local government made codes that discouraged smaller houses. Making them conform to existing codes or getting around codes is a short term solution. The codes should be changed to conform to what is needed.
