Portland's housing problem is multifold. There's not enough single unit housing, but even single family homes are affected by an overly burdensome and expensive permitting process. It adds thousands of dollars to construction and creates a lot of delays so when a house is torn down the lot sits empty. The city also allowed a number of lots to be classified as historical; one near my house is now just a vacant lot that a historical home used to sit on but burned down. You now can't build on that lot. We need to get rid of historical homes in Portland, we need to geographically diversify the housing density, and we need a full scale review of our permitting process.
