It's everywhere. Can't be unwound.
One big irony (which is what modern liberal ideas have a habit of creating) is the fact that a decade or so ago some of this baloney was picthed as a way of keeping housing affordable. Hint: it hasn't worked.
The ratio of land to improvement values has radically shifted toward bare land. And the Portland Metro area real estate prices have moved up so much that homes are not affordable for people with little or no equity, or medium-pay jobs.
Biggest irony? You guessed it. Liberals in the area are spending governement money to look into.....housing affordability.
