2019 is only two months old and it is already the most ambitious year for housing policy in a decade. States and cities are taking up laws that once seemed impossible and issues that once seemed intractable.

The scale of the problem is immense. Home prices are rising twice as fast as wages. According to the National Low Income Housing Coalition, a minimum-wage worker cant afford to rent a two-bedroom apartment anywhere in the country. Homes in many coastal cities now require six-digit down payments, driving up inequality and pushing poor and minority residents further from jobs and schools.

But help is on the way. In the last year, the housing crisis has become a defining political issue in cities across the country, showing up in ballot initiatives, gubernatorial campaigns and municipal debates. Nearly every candidate in the Democratic presidential primary has proposed a plan to address the housing crisis. States and cities, too, have laid out measures unthinkably ambitious just a few years ago.
