While I agree that's a big part of the problem that needs to be solved. I don't think any one thing is going to tackle such a complex multi-faceted issue. For example the book Evicted by Matthew Desmond was a good read and told the story of some families on the edge of homelessness, facing eviction due to various reasons such as drug addiction, low income, etc. These problems won't go away with addressing housing regulations, although more affordable housing availability could certainly help.
