Cities don't have to build housing for people. They just have to make it legal for developers to build it and actually participate in the market. That solves the biggest group of homeless people, those who are down on their luck & couch surfing because they literally cannot afford a house. The second, more visible group, is a completely different story. But just allowing people to build housing instead of creating archaic and backwards rules that prevent any building will solve a huge part of it.
