- In 2021, single-family housing starts reached 1.123 million, the highest since 2006.
- Detached homes have occupied large amounts of land near lucrative job markets.
- The limited supply of buildable residential land is pushing lower-income Americans out of the housing market.
America's suburbs are sprawling again.
Last year, single family housing starts rose to 1.123 million, the highest since 2006, according to the National Association of Home Builders, however, options for prospective homebuyers remain lean.
Experts say the problems of America's housing market relate to past policy decisions. In particular, they say restrictive zoning codes are limiting housing supply. These codes are based on 1930s-era Federal Housing Administration guidelines for mortgage underwriting. That includes "no sidewalks and curvy dead-end streets," according to Ben Ross, author of "Dead End: Suburban Sprawl and the Rebirth of American Urbanism."
Ross and others believe that more must be done to manage residential real estate development. Ross lives in Montgomery County, Maryland, which recently revised its zoning code to bring more population density to the area. The county didn't have many alternative options — 85% of build-worthy land is already developed.
Strict zoning laws favoring single-family homes have limited the supply of land available for multifamily construction and hampered production of more affordable housing. With land limited for multifamily projects, the price of that land has jumped and made those projects unaffordable for builders.
Today's homebuyers are paying for past sprawl by drawing on credit to finance their lifestyles. Meanwhile, the cost of public infrastructure maintenance is weighing on depopulating towns across the country.
