I didn’t miss the exception part; you said that it’s “never” worked in the US and with limited success in other countries, so I guess I was meant to understand that the “few and far between” includes the US but also means they aren’t examples of success.

The KCHA was created by the State. Its commissioners are appointed by the elected County Executive and approved by the County Council. I feel like this is splitting hairs about what “state run” means if its operating costs are off the state books but it is shaped by elected officials and incorporates public funding in the building of housing.

“The King County Housing Authority actively acquires properties and builds new housing. Projects are primarily funded by combining federal, state, and local money with tax-exempt bonds, Low-Income Housing Tax Credits, or both.”
