Changing zoning rules to allow more housing.
The U.S. is short millions of housing units, and the situation is especially tight for those with low incomes.
And one change in particular made national news: The city ended single-family zoning, allowing two- and three-unit homes to be built in every neighborhood.
"We saw Minneapolis add 12% to its housing stock in just that five-year period, far more than other cities," Alex Horowitz, director of housing policy initiatives at Pew, told NPR.
They found that for all the hubbub about duplexes and triplexes in former single-family-only areas, very few have been built.
Zoning reform looks different in every city, according to each one's own history and housing stock.
Changes to allow denser housing in Montana and Austin, Texas, have been blocked by judges after lawsuits from homeowners. »
