If you're looking to block new development, drive up the cost of housing, and appear "progressive" all at the same time, one generally effective technique is to do it under the guise of historic preservation. San Francisco is really good at this, as are many other cities. And it works because, who doesn't think that history is important?

This exact thing just transpired in San Francisco, where earlier this year Supervisor Aaron Peskin passed an ordinance enacting new density controls for most development in the Northeast Waterfront Historic District, the Jackson Square Historic District, and the Jackson Square Historic District Extension (solid neighborhood names).

Of course, sometimes you can run into resistance when you're trying to push through new anti-housing policies. And in this case, San Francisco Mayor London Breed actually vetoed Peskin's bill. In a letter dated March 14, 2024, she wrote:

Restricting new housing runs counter to the goals of our Housing Element, which the Board of Supervisors unanimously approved just over a year ago. It also runs counter to what we need to do to make this City a place that creates opportunities for new homes for the people who need them today and for future generations growing up in San Francisco.

This ordinance passes off anti-housing policy in the guise of historic protections. Existing rules already protect against impacts to historic resources. I believe we can add new homes while also supporting and improving the vibrancy of our unique neighborhoods. Many areas of San Francisco, including eastern neighborhoods like the South of Market, Potrero Hill, and the Mission, have also already removed density limits to encourage new housing.

However, her veto was ultimately overridden by the Board of Supervisors and so, as far as I understand it, the above density controls stand.

What's particularly frustrating about this outcome -- sarcasm now firmly off -- is that it so obviously reeks of NIMBY selfishness. Here's an elaborate infographic created by Max Dubler explaining what many in San Francisco believe is the real reason behind this downzoning:

But like I said, San Francisco seems to be really adept at this sort of maneuvering.
