Housing Prices: The Whole Country Is Starting to Look Like California

Something is happening in the housing market that really shouldn’t be. Everyone familiar with America’s affordability crisis knows that it is most acute in ultra-progressive coastal cities in heavily Democratic states. And yet, home prices have been rising most sharply in the exact places that have long served as a refuge for Americans fed up with the spiraling cost of living. Over the past decade, the median home price has increased by 134 percent in Phoenix, 133 percent in Miami, 129 percent in Atlanta, and 99 percent in Dallas. (Over that same stretch, prices in New York, San Francisco, and Los Angeles have increased by about 75 percent, 76 percent, and 97 percent, respectively).

This trend could prove disastrous. For much of the past half century, suburban sprawl across the Sun Belt was a kind of pressure-release valve for the housing market. People who couldn’t afford to live in expensive cities had other, cheaper places to go. Now even the affordable alternatives are on track to become out of reach for a critical mass of Americans.

The Sun Belt, in short, is subject to the same antidevelopment forces as the coasts; it just took longer to trigger them. Cities in the South and Southwest have portrayed themselves as business-friendly, pro-growth metros. In reality, their land-use laws aren’t so different from those in blue-state cities. According to a 2018 research paper, co-authored by Gyourko, that surveyed 44 major U.S. metro areas, land-use regulations in Miami and Phoenix both ranked in the top 10 most restrictive (just behind Washington, D.C., and L.A. and ahead of Boston), and Dallas and Nashville were in the top 25. Because the survey is based on responses from local governments, it might understate just how bad zoning in the Sun Belt is. “When I first opened up the zoning code for Atlanta, I almost spit out my coffee,” Alex Armlovich, a senior housing-policy analyst at the Niskanen Center, a centrist think tank, told me. “It’s almost identical to L.A. in the 1990s.”

These restrictive rules weren’t a problem back when Sun Belt cities could expand by building new single-family homes at their exurban fringes indefinitely. That kind of development is less likely to be subject to zoning laws; even when it is, obtaining exceptions to those laws is relatively easy because neighbors who might oppose new development don’t exist yet. Recently, however, many Sun Belt cities have begun hitting limits to their outward sprawl, either because they’ve run into natural obstacles (such as the Everglades in Miami and tribal lands near Phoenix) or because they’ve already expanded to the edge of reasonable commute distances (as appears to be the case in Atlanta and Dallas). To keep growing, these cities will have to find ways to increase the density of their existing urban cores and suburbs. That is a much more difficult proposition. “This is exactly what happened in many coastal cities in the 1980s and ’90s,” Armlovich told me. “Once you run out of room to sprawl, suddenly your zoning code starts becoming a real limitation.”
