Research published in June by the Journal of the American Planning Association examined zoning changes in major U.S. metropolitan areas from 2003 to 2019, finding that zoning grew more accommodating to apartments in strong-market metro areas over that time period.

In addition to the abstract, which is available online, the researchers—Rolf Pendall, Lydia Lo, and Jake Wehmann—provide this "takeaway for practice":

Local land use planners in the United States have ethical and legal obligations to undo the racial segregation designed into zoning from its founding. They also must prepare for continued population growth. Tools and strategies exist to do both of these, and some planners have the commitment and political space to use them. In other places, planners and their professional organizations need to change rules within their own communities and advocate for state legislative reforms so that planning works predictably to unwind unequal and exclusionary settlement patterns within neighborhoods and cities.

The study's abstract suggests that the findings function as a counter-narrative to opinions of pundits and economists that zoning explains housing price inflation in fast-growth metro areas. This research shows the limitation fo the narrative, according to the authors. 

For more of the ongoing debate about zoning's role in the housing market, and attempts by local jurisdiction to create more affordable housing supply by loosening zoning restrictions on multi-family housing, see the collection of articles flied under Planetizen's Zoning Reform tag.

The article's abstract and a link to the (paywalled) study is available below. To access some of the research without a paywall, see also a follow up brief built on the original study, recently published by the Urban Institute and written by Patrick Spauster, Lydia Lo, and Yonah Freemark.

The Roadway Expansion Paradox

Motorists want expensive roadway expansions provided that somebody else foots the bill, but when required to pay directly through tolls, the need for more capacity often disappears. What should planners do?
