Oregon eliminated burdensome parking regulations in most larger cities and: it's fine.
Many home builders still add parking to new projects because there is market demand for it - and they are also competing for tenants or buyers against existing housing which has parking.
But there is now the flexibility to do some projects without parking, which really helps at the affordable end of the spectrum, and is a good fit for more walkable locations.
BTW, Nolan Gray, cited as the author, has a book out himself that's really approachable and good reading if you're interested in cities: https://islandpress.org/books/arbitrary-lines
