Every city in the state of California for many decades has failed to build enough housing to address the ever increasing demand for it and as a result people are losing housing. Every time rent increases significantly, homelessness increases significantly. The cost of housing in California cities and the Bay Area in particular has never decreased or even stabilized because we treat housing as an investment, keep it scarce through a number of local and statewide impediments to building, and expect outrageous returns on existing housing over time.
