There is a good article about one in Boulder

It is the same story all over. People are experiencing mental health and substance abuse issue, the rent is too damn high and become unhoused. Temporary unhoused shelters are never a good solution, because they are not safe. A lot of unhoused people feel safer sitting in open public space than cramped up in shelters with other unhoused people, especially in places where the weather is usually manageable like Colorado.
The solution is to build permanent apartment for the unhoused, so they can live with dignity without rent burden. And then most people can work on other aspects of their lives, like finding a job, getting an education, etc. But why would the private sector build permanent housing for people who don't have money? They would rather buy 3-4 houses in a row, bulldoze them and build a luxury apartment complex for the techbros in the city.
