housing has become a key political issue in bay area elections. in november 2015, san francisco voters rejected two ballot propositions both of which were claimed by their supporters to reduce the crisis. the first, proposition f, would have enacted a number of restrictions on airbnb rentals within the city. the second, proposition i or the "mission moratorium", would have blocked all housing development in san francisco's mission district for 18 months, except for developments in which every apartment was subsidized at a below-market rate.
