A new Housing Policy Toolkit from the White House admits that “local barriers to housing development have intensified,” which “has reduced the ability of many housing markets to respond to growing demand.” The toolkit, however, advocates tearing down only some of the barriers, and not necessarily the ones that will work to make housing more affordable.
“Sunbelt cities with more permeable boundaries have enjoyed outsized growth by allowing sprawl to meet their need for adequate housing supply,” says the toolkit. “Space constrained cities can achieve similar gains, however, by building up with infill.” Yet this ignores the fact that there are no cities in America that are “space constrained” except as a result of government constraints. Even cities in Hawaii and tiny Rhode Island have plenty of space around them–except that government planners and regulators won’t let that space be developed.
Instead of relaxing artificial constraints on horizontal development, the toolkit advocates imposing even tighter constraints on existing development in order to force denser housing. The tools the paper supports include taxing vacant land at high rates in order to force development; “enacting high-density and multifamily zoning,” meaning minimum density zoning; using density bonuses; and allowing accessory dwelling units. All of these things serve to increase the density of existing neighborhoods, which increases congestion and–if new infrastructure must be built to serve the increased density–urban-service costs.
