Seattle is doing a much better job than SF, but they're also still doing a terrible job. Most of the residential land is still zoned for super low density housing, even though it's a major city. It's absurd, but people accept it because it's one of those American absurdities, like people dying because they couldn't afford health coverage.
Single family home-only zoning is economically segregationist, and should not exist. It's fine if people want to own a single family home themselves, but wrong to keep the poor and working class out of their neighborhood by making that type of home mandatory.
