Portland Just Passed the Best Low-Density Zoning Reform in US History

"Portland’s city council set a new bar for North American housing reform Wednesday by legalizing up to four homes on almost any residential lot.
Portland’s new rules will also offer a “deeper affordability” option: four to six homes on any lot if at least half are available to low-income Portlanders at regulated, affordable prices. The measure will make it viable for nonprofits to intersperse below-market housing anywhere in the city for the first time in a century.
And among other things it will remove all parking mandates from three quarters of the city’s residential land, combining with a recent reform of apartment zones to essentially make home driveways optional citywide for the first time since 1973.
It’s the most pro-housing reform to low-density zones in US history."
