Minneapolis and Seattle are among cities that have effectively abolished zoning that restricts neighborhoods to owner-occupied, single-family dwellings. Oregon has done so in its largest municipalities, and Californians, like residents of Salt Lake City, are now free to build small cottages, sometimes called “granny flats,” for use as rentals in neighborhoods that were previously single-family only…
Before World War II, only about 13% of Americans lived in a suburb; now more than half of us do, and as the New York Times reported, in many American cities, more than 75% of residential land is zoned for single family use only.
In some cities, the share is even higher: in Charlotte, North Carolina, for example, 84% of residential land is zoned single-family; in San Jose, California, 94% is, according to a Times analysis in collaboration with UrbanFootprint…
Other states with single-family zoning in the legislative crosshairs in 2020 include Virginia and Maryland, where House Delegate Vaughn Stewart says upzoning can correct social-justice issues, as well as housing problems. “For too long, local governments have weaponized zoning codes to block people of color and the working class from high-opportunity neighborhoods,” Stewart told Kriston Capps of CityLab.
Sonia Hirt, quoted in this article, argues that single-family homes drive zoning in the United States as the goal is to protect homes and homeowners from uses they find less desirable, threatening to a residential character, and negatively impact property values.
As someone who studies suburbs, zoning, and housing, here are a few thoughts about the future of these changes:
- Making changes at the city or municipal level will be easier or more palatable to more voters who tend to like local control over land use decisions. If zoning changes are made at the state level, it will be harder to enforce the guidelines or penalize communities that do not comply.
- Wealthier communities will fight hard to avoid these zoning changes. Part of the appeal for some to move to wealthier suburbs is to keep others out and have a particular aesthetic (and these homeowners usually are not looking for more density).
- Adding some accessory dwellings throughout single-family home neighborhoods may not change the character of communities much but asking for bigger changes – multi-family housing, apartments, condos, turning large single-family homes into multiple units – on a bigger scale will be a tough sell in many communities.
These difficulties suggest progress in providing more affordable housing or more housing units could be slow. If change and enforcement primarily happens at the local level, this limits the ability of regions to address affordable housing issues because the problem simply becomes one that other communities should address. Housing, like transportation or water, is an issue that benefits greatly from the cooperation of all actors in a region. While it is a difficult topic to address at this level, let alone a national level, significant progress requires broader cooperation and efforts.
