Leaving something up to developers resulted in McMansions. This has been studied a lot and the results are clear.
One, directed policy is the fastest way to affordable housing.
Two, affordable doesn’t mean slums. This isn’t Section 8. This is the government setting policy that dense housing needs to be build near transit centers. Wow. What a concept. I would take it a step further and require certain building practices that increase the expected lifespan of the condo. It can be done without looking like a 70s prison.
Stop letting people build anywhere without penalty. Have defined city limits with dense housing and transit / walk ability to go with it.
So many things you can do we don’t do. More people should live aboard.
