Review: Homelessness is a Housing Problem

In Homelessness is a Housing Problem, Prof. Gregg Colburn and data scientist Clayton Page Aldern seek to answer the question: why is homelessness much more common in some cities than in others? They find that only two factors are significant: 1) overall rents and 2) rental vacancy rates. Where housing is scarce and rents are high, lots of people are homeless. Where rents are lower, fewer people are homeless, even in very poor places. (In fact, high city incomes correlate positively with homelessness, because more and better jobs lead to higher demand for housing). By contrast, many other factors that one might think are related to homelessness in fact are not correlated on a citywide basis. For example, since homeless people are generally poor, one might think that places with high poverty rates or high unemployment rates have lots of homelessness. The authors show that this is not the case. Where most people are poor, there is less demand for housing, which translates into lower rents and less homelessness. One might also think that places with warm weather have lots of homelessness, because homeless people might be attracted to them. But high-rent cold cities like Boston have above-average levels of homelessness, while cheaper warm-weather cities like Orlando and Charlotte do not. However, homeless people are more likely to have temporary shelter in cold cities than in expensive warm-weather cities like San Diego- either because city governments are less motivated to build homeless shelters when no one is at risk of freezing to death, or because the homeless themselves are less eager to use shelters. I suspect that if the authors focused only on highly visible unsheltered homelessness, they might have found a stronger correlation with weather). It might be argued that shelters themselves (or other social services) attract the destitute. […]

The “outer boroughs” myth

One argument against bus lanes, bicycle lanes, congestion pricing, elimination of minimum parking requirements, or indeed almost any transportation improvement that gets in the way of high-speed automobile traffic is that such changes to the status quo might make sense in the Upper West Side, but that outer borough residents need cars. This argument is based on the assumption that almost anyplace outside Manhattan or brownstone Brooklyn is roughly akin to a suburb where all but the poorest households own cars and drive them everywhere. If this was true, outer borough car ownership rates and car commuting rates would be roughly akin to the rest of the United States. But in fact, even at the outer edges of Queens and Brooklyn, a large minority of people don’t own cars, and a large majority of people do not use them regularly. For example, let’s take Forest Hills in central Queens, where I lived for my first two years in New York City. In Forest Hills, about 40 percent of households own no car. (By contrast, in Central Islip, the impoverished suburb Long Island where I teach, about 9 percent of households are car-free- a percentage similar to the national average). Moreover, most of the car owners in Forest Hills do not drive to work. According to the U.S. Census Bureau’s American Community Survey (ACS), only 28 percent of the neighborhood’s workers drive or carpool to work. Admittedly, Forest Hills is one of the more transit-oriented outer borough neighborhoods. What about the city’s so-called transit deserts, where workers rely solely on buses? One such neighborhood, a short ride from Forest Hills, is Kew Gardens Hills. In this middle-class, heavily Orthodox Jewish neighborhood, about 28 percent of households are car-free- not a majority, but again high by American or suburban standards. And even […]

What’s a stickplex?

  A stickplex is a dense residential structure or group of structures built with inexpensive materials and techniques, most commonly wood. Stickplexes use 2,500 square feet of land per unit or less. Stickplexes have per-square-foot construction costs roughly in line with detached houses due to avoidance of costly features like elevators and more expensive construction methods. This type of housing includes features of both multifamily housing and single-family housing. They economize on land while avoiding the high construction costs of large multifamily buildings. Relative to high-rise housing, stickplexes can cost one-third less to build on a per-square-foot basis. And because they use a relatively small amount of land per unit, their land costs are lower than the typical detached house’s land costs.  Stickplexes versus missing middle Daniel Parolek coined the term “missing middle” and emphasizes that missing middle “is compatible in scale with single-family homes.” He advises caution about permitting three-story buildings, while a stickplex can be three stories or taller. A duplex on a 6,000 square foot lot would fit the definition of missing middle. But it would not be a stickplex since it would use more than 3,000 square feet of land per unit. Missing middle housing has found traction politically. Policymakers who have passed zoning reforms from Oregon to Nebraska to Durham have used the term to describe the type of construction they would like to see. Minneapolis Council Member Lisa Goodman described the city’s reform to permit triplexes in language similar to Parolek’s: “I like to refer to it as, ‘the box can’t change,” she said. “All that can change is how many families can live within the existing box.” However, in Minneapolis, questions remain about how feasible triplexes will be to build in permitted building envelopes. Zoning rules, including floor area ratio limits of less than one […]

Get the tuck out of here

In two previous posts, I’ve raised questions about the competitiveness of missing middle housing. This post is more petty: I want to challenge the design rigidities that Daniel Parolek promotes in Missing Middle Housing. Although petty, it’s not irrelevant, because Parolek recommends that cities regulate to match his design goals, and such regulations could stifle some of the most successful contemporary infill growth. Parolek’s book suffers from his demands that missing middle housing match his own tastes. For instance, he has a (Western?) bias against three-story buildings. Having grown up in the Northeast, I think of three stories as the normal and appropriate height for a house. To each his own – but Parolek’s constant insistence on this point offers aid to neighborhood defenders who will be happy to quote him to make sure three-story middle housing remains missing. The house in the doghouse No form is in Parolek’s doghouse as much as the “tuck-under” townhouse, an attached house with a garage on the first floor. This is clearly a building that builders and buyers love: “If your regulations do not explicitly prohibit it, it will be what most builders will build” (p. 140). In fact, tuck-under townhouses are probably the most successful middle housing type around. In lightly-regulated Houston, builders small and large have been building townhouses, sometimes on courtyards perpendicular to the road. Parking is tucked. Townhouses are usually three stories tall (bad!), sometimes four. A few are even five stories. Their courtyards are driveways (also bad!). In a very different context – Palisades Park, NJ – tuck-under duplexes are everywhere. Their garages are excessive thanks to high parking minimums, but the form has been very successful nonetheless. These examples are not to be dismissed lightly: these are some of the only cases where widespread middle housing is […]

Stuck in the (Missing) Middle

Everybody loves missing middle housing! What’s not to like? It consists of neighborly, often attractive homes that fit in equally well in Rumford, Maine, and Queens, New York. Missing middle housing types have character and personality. They’re often affordable and vintage. Daniel Parolek’s new book Missing Middle Housing expounds the concept (which he coined), collecting in one place the arguments for missing middle housing, many examples, and several emblematic case studies. The entire book is beautifully illustrated and enjoyable to read, despite its ample technical details. Missing Middle Housing is targeted to people who know how to read a pro forma and a zoning code. But there’s interest beyond the home-building industry. Several states and cities have rewritten codes to encourage middle housing. Portland’s RIP draws heavily on Parolek’s ideas. In Maryland, I testified warmly about the benefits of middle housing. I came to Missing Middle Housing with very favorable views of missing middle housing. Now I’m not so sure. Parolek’s case for middle housing relies so much on aesthetics and regulation that it makes me wonder whether middle housing deserves all the love it’s currently getting from the YIMBY movement. Can middle housing compete? Throughout the book, Parolek makes the case that missing middle construction cannot compete, financially, with either single-family or multifamily construction. That’s quite contrary to what I’ve read elsewhere. In a chapter called “The Missing Middle Housing Affordability Solution”, Daniel Parolek and chapter co-author Karen Parolek write: The economic benefits of Missing Middle Housing are only possible in areas where land is not already zoned for large, multiunit buildings, which will drive land prices up to the point that Missing Middle Housing will not be economically viable. (p. 56) On page 81, we learn, It’s a fact that building larger buildings, say a 125-150 unit apartment […]

Against Spot Text Amendments

As zoning has become more restrictive over time, the need for “safety valve” mechanisms—which give developers flexibility within standard zoning rules—has grown exponentially. U.S. zoning officially has two such regulatory relief mechanisms: variances and special permits. Variances generally provide flexibility on bulk rules (e.g. setbacks, lot sizes) in exceptional cases where following the rules would entail “undue hardship.” Special permits (also called “conditional use permits”) generally provide flexibility on use rules in cases where otherwise undesirable uses may be appropriate or where their impacts can be mitigated. An extreme grade change is one reason why a lot might receive a variance, as enforcing the standard setback rules could make development impossible. Parking garages commonly require special use permits, since they can generate large negative externalities if poorly designed. Common conditions for permit approval include landscaping or siting the entrance in a way that minimizes congestion.  (Wikipedia/Steve Morgan) In addition to these traditional, formal options, there’s a third, informal relief mechanism: spot zoning. This is the practice of changing the zoning map for an individual lot, redistricting it into another existing zone. Spot zonings are typically administered where the present zoning is unreasonable, but the conditions needed for a variance, special permit, or a full neighborhood rezoning aren’t. In many states, spot zonings are technically illegal. The thinking is that they are arbitrary in that they treat similarly situated lots differently. But in practice, many planning offices tolerate them, usually bundling in a few nearby similarly situated lots to avoid legal challenge. An example of a spot zoning. Variances, special permits, and spot zonings are generally considered to be the standard outlets for relief from zoning. But there’s a fourth mechanism that, to my knowledge, hasn’t been recognized: let’s call it the “spot text amendment.” Like spot zonings, spot text amendments […]

A great new paper on how government fights walking

Many readers of this blog know that government subsidizes driving- not just through road spending, but also through land use regulations that make walking and transit use inconvenient and dangerous.  Gregory Shill, a professor at the University of Iowa College of Law, has written an excellent new paper that goes even further. Of course, Shill discusses anti-pedestrian regulations such as density limits and minimum parking requirements.  But he also discusses government practices that make automobile use far more dangerous and polluting than it has to be.  For example, environmental regulations focus on tailpipe emissions, but ignore environmental harm caused by roadbuilding and the automobile manufacturing process.  Vehicle safety regulations make cars safer, but American crashworthiness regulations do not consider the safety of pedestrians in automobile/pedestrian crashes.   Speeding laws allow very high speeds and are rarely enforced.
