Housing costs are exaggerated in San Francisco by orders of magnitude more than every other component of cost of living.

There are other factors that also push up housing costs. placeybordeaux just disagrees that NIMBYism is the ONLY factor. I don't know if NIMBYism is even the primary factor.

For example, we have a small public transit network resulting in few options for high density construction.

There's a construction labor shortage that will likely worsen.

There's a sudden surge in jobs.

No, I don't think the GP is. But it's a rather predominant factor!
