On its front page today, the Washington Post writes about legal and regulatory obstacles to building small second housing units on single‐family lots, often for aging family members.
Second homes, often called “granny flats,” have become a new front in the conflict that pits the need for more housing in the country’s most expensive cities against the wishes of neighbors who want to preserve their communities. The same battles flare over large developments that might loom over single‐family neighborhoods. But even this modest idea for new housing — let homeowners build it in their own back yards — has run into not‐in‐my‐back‐yard resistance.…
Homes like the Coffees’, proponents argue, could help ease housing shortages that have made $2,000-a-month one‐bedrooms look like a bargain in cities such as Los Angeles. They could yield new affordable housing at no cost to the public. They could add rentals and economic diversity to more neighborhoods. And they could expand housing options for a population in which baby boomers are aging and millennials are stuck at home.
Many neighbors, though, protest that a glut of back yard building would spoil the character of neighborhoods designed around the American ideal of one family on one lot surrounded by verdant lawn. …
“You have surging housing prices in the most prosperous cities in the country, and at the same time income inequality is growing, and there’s a cultural and demographic resurgence of urban living,” [Alan Durning, executive director of the Sightline Institute] said. Young people with less money, in particular, he adds, are “slamming into their parents and grandparents’ regulatory regimes of strict limits on construction of new housing.”
It’s not the first time I’d heard of the problem. In 1996 George Liebmann wrote in Regulation about how “Zoning makes it more difficult to keep aged parents close by and care for them.” He recommended that “Duplex homes and accessory apartments should be permitted in all new residential construction. Housing options such as these allow elderly persons to live near their adult children without intruding on their children’s privacy.” (“Modernization of Zoning,” pp. 71, 75). Note that he was talking not about separate structures but simply residential units attached to the main house. And even those were impeded by zoning regulations. I mentioned them briefly in my 1997 book Libertarianism: A Primer and my 2015 update, The Libertarian Mind (p. 309).
Local officials think their zoning rules are more important than keeping families together. They fume that allowing such small structures for grandma would “turn our zoning ordinance upside down.” And what’s more important, saving money and keeping grandma near her family or strict adherence to zoning regulations? The Post article, featuring a conflict in Los Angeles, notes the problem of NIMBY or “not in my back yard” attitudes by neighbors. And in this case, as reporter Emily Badger notes, it’s actually in your back yard. Or technically, it’s a matter of “not in my neighbor’s back yard.”
Brink Lindsey wrote about how zoning limits affordable housing in his recent paper on regressive regulation, as did Edward Glaeser and Joseph Gyourko in Regulation.
