Today’s affordability gap: Part 3, why
[Continued from Part 1 and Part 2.]
In Parts 1 and 2 we followed Michael Grunwald’s Washington Post essay on the rising income floor needed to afford market housing — but if there are people with money to pay for housing, why isn’t there more housing to buy with it?
In many communities, local regulations have stifled multifamily housing and even modest single-family housing. Minimum lot requirements, minimum parking requirements, density restrictions and other controls go well beyond the traditional mission of the building code and end up artificially reducing the development of safe, affordable housing.
A locality controls its property development with two levers:

A lot depends on the dummies pulling the levers
· Zoning, which caps the amount and type of development.
· Real estate taxation, which incentivizes some uses (and thereby implicitly dis-incentivizes others).
The unfashionable but accurate term for these restrictions is “snob zoning.” Suburbanites use them to boost property values by keeping out riffraff — even the riffraff who teach their kids, police their streets and extinguish their fires. Urbanites are susceptible to the same NIMBY impulses, often couched as opposition to “traffic congestion” or “overdevelopment” or protection of the neighborhood’s “character.” It’s easy to support affordable housing in someone else’s neighborhood. But when developers propose high-density projects, neighborhoods object.
I wish I could point to a long list of liberal communities that have put their buildings where their editorials are by embracing affordable housing.
But I can’t.
That’s an astonishing density increase — and well located.

The project will increase the supply of job-accessible housing and take commuters out of their cars; the county is even forcing the developer to set aside a small percentage of moderate-income units in exchange for an exemption from its anti-density rules.
Example of local levers being pulled: inclusionary zoning and density bonus.
But the

Maybe they’ll approve it next year?
Still,
I’ve documented frequently that inclusionary zoning — in effect, a tax on land or land development rights — is particularly effective in local contexts since it interpenetrates a small percentage (usually up to 25%) of affordable homes within a larger, market-oriented development. This pepper-potting (as the British evocatively phrase it) enables the affordable homes and residents to blend in.

This is a new workforce variant: the in-week apartment enabling someone to raise a family far away. It’s a means of remitting earnings from the city to the homestead, one we see throughout the world, in varying income levels and with varying housing consumption.
But these local projects address only a tiny fraction of the demand. For example,

What new housing
The main obstacle, Thornberg concludes, is “the intransigence of local zoning boards.”
In other words, the best thing local officials can do to promote affordable housing is to get out of the way — stop requiring one-acre lots and two-car garages, and stop blocking low-income and high-density projects.
It requires more than the laissez-faire no-zoning
Bush proposed a home-ownership tax credit during his 2000 and 2004 campaigns, but it turned out to be the rare tax cut he didn’t pursue.
A bill pending in Congress would divert a percentage of profits [5% -- Ed.] from federally chartered institutions such as Fannie Mae to a national affordable-housing trust fund, but it seems stalled. The only affordability ideas with any traction at the national level are not really housing ideas; for example, one way to make housing more affordable to workers would be to raise their incomes — through higher minimum wages, lower payroll taxes or an expanded Earned Income Tax Credit.
There are times when political force yields policy ideas, but every now and then the idea itself can create some political force. We’ve seen that nationwide there’s plenty of local interest in workforce housing affordability — how can we translate it into a national program?
For that we’ll have to turn to Recap’s Web Update 58, and …
