I live in San Francisco. You’ve all heard about the cost of housing here. The main reason, in my opinion, is that housing stock is very low compared to the demand - one regional government body estimated that the gap between supply and demand is 100,000 units (something between 10% and 15% of current stock). SF is fairly unique as a city, in that there is zero room to expand except to the south, and the peninsula is already pretty well built up and only slightly less expensive than the city. New housing construction pretty much has to fill in existing neighborhoods, making them more densely populated.
SF has a pretty good public transportation infrastructure, but it is often very crowded and unpleasant to use. They need to run more frequently, I’m not sure why they don’t except for the cost of the additional buses/streetcars, and the cost of the labor to run them. The city wants developers to build multi-housing units with relatively little parking, as they are trying to get people out of their cars. The result is that the new residents park on the street, which infuriates the existing neighborhood. The result of that is that neighborhoods tend to put every roadblock they can think of in the way of new projects.
The mayor has recently issued a very thorough directive to city agencies to streamline the permitting process for housing projects, which may help with one part of the problem. There was also a recent state bill to reduce restrictions on in-law type units for single-family homes. This was over a year ago and little seems to have change on that front. There are laws about percentage of “affordable” units associated with any new housing project. This patently doesn’t work.
So there is a deep tension between the need to increase housing density, and the desire of current residents not to lose the character and livability of their neighborhoods. Also there is a gap between the city’s desire to reduce dependence on private vehicles and the ability of public transportation to keep up with current demand, let alone the demand increase stemming from an increased population. The problems are way more complex than I can outline in one or a dozen posts, but I think these two are among the most difficult issues. The city’s current path of becoming an enclave for the rich is not sustainable.
What perspectives are we missing? Where are the fresh ideas?
