What causes housing in the US to be too expensive
The U.S. has two big housing affordability problems. They’re related — and solving the first would go some way toward solving the second. But they’re not the same, and it’s important to understand that.
The first problem is that some coastal metropolitan areas in the U.S. are generating lots of good jobs but aren’t building enough housing to keep up with employment growth. The main barrier to housing construction in these places is local regulation — zoning ordinances, environmental requirements, even affordable-housing rules. This problem has been getting a lot of attention lately. I’ve written about it several times over the past year, and it’s the subject of new pieces in the past few days from the Economist and the New York Times:
The second housing affordability problem is less geographically limited, and more chronic: Millions of Americans can’t afford even the cheapest housing. Here’s Jason DeParle in the New York Review of Books:
“The big problem is that it costs more to build even modest housing than millions of households can pay, whether the builder is greedy or not. That’s partly because restrictive zoning and overzealous building codes drive up the price. But it’s mostly because of the inherent cost of the basics: land, interest, materials, utilities. As a rule of thumb nationwide, even an efficient nonprofit developer can’t build an apartment affordable to a household making less than about $32,000 a year. That leaves out nearly a third of American households.”
Now, there’s an issue with using the cost of building new housing as the cutoff point. As economic consultant Joe Cortright wrote for City Observatory in February:
“In the United States, we have almost never built new market-rate housing for low-income households. New housing — rental and owner-occupied — overwhelmingly tends to get built for middle- and upper-income households. So how do affordable market-rate housing units get created? As new housing ages, it depreciates, and prices and rents decline, relative to newer houses.”
If we built lots of new housing that poor people can’t afford, the thinking goes — and there’s economic evidence to back it up — that will make existing housing cheaper, and some of it will fall into a price range where some households making less than $32,000 a year can afford it. That’s how solving the first affordability problem can help solve the second one.
Still, I can’t imagine that new construction alone will make housing affordable for everyone. Some housing will get cheaper, and some households making less than $32,000 will be able to move in. Most will still find it really hard, though. The Jason DeParle quote above is from his review of sociologist Matthew Desmond’s new bestseller, “Evicted: Poverty and Profit in the American City,” which details the troubled lives of low-income renters in Milwaukee. (I haven’t read the book, but I have read the New Yorker article adapted from it.) As DeParle recounts in his review, one character in the book is evicted from an apartment where the $550 rent takes up 88 percent of her income, and later moves to one where the rent is 96 percent. Nationwide, about half of poor households spend more than 50 percent of their income on housing.
DeParle, a New York Times reporter who’s been writing about poverty and government efforts to combat it for more than two decades, offered this short history of housing affordability:
