San Francisco has become one of the most expensive cities in the country. The cost of living here is driving out the city’s cultural diversity. For the vast majority of the people affected, the problem can only be addressed through a dramatic expansion of the supply of housing. SPUR’s Housing Committee has the job of proposing policy changes that will increase the supply — and bring down the cost — of housing. It has put forward a series of policy papers that point the way out of the crisis. Work continues on this task of generating ideas that can be implemented today, on a local level.
