Zoning trade-off: privacy vs. adverse effects

The conclusion of Sonia Hirt’s book Zoned in the USA sums up the advantages and disadvantages of a zoning system that privileges the single-family home:

Arguably, zoning – the kind of zoning that makes explicitly private space the formative compositional element of America’s settlements – does deliver the gift of privacy to American families. But put all the other arguments mentioned in the previous paragraphs together, and one begins to wonder whether the original promises of zoning were either highly suspect from the beginning or have since been turned on their heads. Paradoxically (from the viewpoint of zoning’s founders), we may not have more pollution and worse public health with our current zoning that we would have if we had modified our land-use laws more substantially over the last hundred years.

As Hirt discusses, residents can have their own private homes – the largest new single-family homes in the world – but that comes at a cost of traffic and commuting, worse pollution and using more land, and worse health as well as some unrealized dreams of zoning including reduced crime. Some would argue that the privacy is overrated as well: compared to many other countries, Americans have given up on public life.

While it is easier to imagine mixed uses in dense urban neighborhoods – imagine Jane Jacobs’ vision of a bustling mixed use New York neighborhood – it is harder to imagine mixed use or zoning throughout the vast expanses of American suburbs. Even New Urbanists have tended to design neighborhoods or shopping centers dropped into suburban settings rather than the whole fabric of suburban communities. From the beginning of American suburbs, there was the idea that the urban dweller was escaping to a cottage in nature. The home out there offered refuge from people, dirt, and bustle. Today, this legacy lives on when suburban residents oppose certain land uses near their homes for fear of a lower quality of life and subsequently reduced property values.

Ultimately, would the American suburbs even exist without the fundamental desire for privacy?

A zoning paradox: sacred residential spaces are dependent on their market values

The last page of Sonia Hirt’s book Zoned in the USA lays out a key paradox in the American zoning system:

Isn’t it ironic that American residential space is so sacredly residential (so protected from intrusion through land-use law, that is) only because it is so commercial (because it is an object of trade rather than an object of our sentiments)?

Perhaps this another piece of evidence that single-family homes are one of the biggest objects of American consumption as well as key pieces in the American economic system.

Small house movement spreads in ADUs

One way to encourage smaller homes and affordable housing is to allow Accessory Dwelling Units:

The cottage, which won a top design award last year from the American Institute of Architects, is technically called an “accessory dwelling unit,” or A.D.U. Portland has been ahead of the curve in allowing these smaller housing units, which are illegal in many cities and towns under current zoning rules…

In 2010, during the economic slump, when many building plans were being shelved, Portland presciently began to allow homeowners the right to develop accessory dwelling units on standard 5,000-square-foot residential lots for the first time. The city also eliminated development charges of up to $15,000 for new accessory dwelling units to spur homeowners to build.

More incentives followed: Homeowners could build and even rent out a unit that did not have off-street parking; any design not visible from the street could be built without input from neighbors; and new height limits — raised to 20 feet from 18 feet — encouraged two-story units, like Ms. Wilson’s…

Not surprisingly, the concentration of accessory dwelling units has been in central, higher-income areas close to amenities like transit and shops. “Part of this could be due to the fact that people with large amounts of equity can more easily secure financing,” Mr. Wood said. “The City of Portland and Portland State University will be working on a project to encourage and facilitate A.D.U. development in more diverse neighborhoods.”

It may be helpful to compare the ADUs to other alternatives for affordable, small housing.

  1. Would residents and communities prefer tiny houses on their own lots or in communities of tiny houses? The first could be expensive due to the cost of land, defeating the purpose of the smaller housing which is supposed to be cheaper. The second could be too much of a change for some places. ADUs make use of existing lots and aren’t necessarily grouped together.
  2. Would residents and communities prefer larger apartment buildings? On the plus side, you can build more units up and everyone knows that this is an apartment structure (with its higher densities and other unique features). On the negative side, apartment buildings can alter the character of a neighborhood, may require parking, and people often have stereotypes about who lives in apartments. The ADUs hide the higher densities better than apartments – back behind the main housing unit – but don’t provide as many units.

Given the resistance of many municipalities to denser housing, I imagine ADUs could be attractive as they don’t require the density or size of some alternatives. Additionally they can use existing land and generate income for local residents. Even given all that, I think it would take a lot for many cities to adopt this. There is a large need for affordable housing throughout the United States and many communities don’t seem to be moved to do anything; I’m not sure ADUs are attractive enough to tilt the scales.

 

The Chicago of today influenced by 1920s zoning decisions

A new study suggests the beginning of zoning in Chicago had long-lasting effects:

Walsh and two other urban economists investigated zoning’s long-term effects in Chicago, using 1920s parcel-level data on land use and market values prior to, and immediately after, the adoption of the city’s first comprehensive zoning ordinance in 1923. They compared these early quilts of land use to that of the present day (or, at least, to the most recent complete dataset available, which came from 2005).

Contrary to what many economists may believe, they first found that zoning did not merely ratify existing land uses. Lot by lot, they found significant variation between the activities that predated zoning and those that came after, especially as years went by. For example, some factories and shopping areas that didn’t conform to the 1923 code were allowed to stay in their respective locations, thanks to a “grandfather” clause. But over time, the vast majority of them disappeared. The powerful force of zoning can be seen on a citywide scale, too: Whereas 82 percent of Chicago’s developed blocks had some form of commerce happening in 1922, that share had dropped by about half by 2005, researchers found.

In other words, the way Chicago looks in the 21st century tracks much more closely with the desires of its planners in 1923 than it does with the city that preceded zoning. This fact has had a huge effect on economic patterns, too. For example, the researchers found that exclusive residential zoning had a significant impact on home prices, driving up values in neighborhoods cordoned off for single-family homes. On a citywide level, they used a regression analysis to find that the zoning code of 1923 had bigger role in shaping economic patterns—i.e., where commercial and industrial activity is going on today—than either pre-existing transportation networks or geography, two factors you might think would best explain why there’s a factory by the old railroad tracks, or a shopping district near downtown…

Although the present paper didn’t explicitly analyze how Chicago’s old zoning codes have influenced racial segregation, a companion paper published in Julyby the same researchers found that the laws drawn up in 1923 were discriminatory: Areas with more black residents were zoned for higher-density housing, and “neighborhoods with larger populations of blacks or recent immigrants were zoned disproportionately for manufacturing.” Chicago consistently ranks as among the most segregated cities in the U.S., and its present-day economic divisions track closely with race (as well as with municipally recognized community boundaries). It wouldn’t be surprising to learn that zoning laws (much like housing policy) dating back a century are in some ways responsible. That’s a theory that needs investigation, Walsh says.

Zoning decisions are political ones. The suggestion here is that if the decisions are good ones, they can have positive effects for decades. The converse – particularly when used to limit options for particular groups – is also true.

The last paragraph of the article hints at recent suggestions regarding significant changes to urban zoning. It would be interesting to see what average Americans think of such ideas: would they trade predictability for flexibility? Continue with the example of Chicago: would more flexible zoning allow for the construction of more affordable housing or would it mean that more land would be converted to non-residential uses, limiting housing options? New Urbanists have touted mixed-use zoning for a long time but their vision of this is often limited to particular kinds of businesses or offices as well as nicer housing (even if it includes different price ranges).

The common uniformity of prison and suburban design

In A Burglar’s Guide to the City, a reformed bank robber describes a realization he had while walking through the suburbs of southern California:

For Loya, linguist George Lakoff’s book Metaphors We Live By took an unexpected spatial resonance, revealing ways in which the built environment could be read or understood as a series of metaphors or signs. He said that after being released from prison, he spent a lot of time taking long walks around the suburban landscape of Southern California. He began noticing that every twenty-five feet, he would hit a driveway; he’d then walk eight feet across the driveway before hitting another stretch of grass; then another twenty-five feet to the next driveway, and so on, seemingly forever, “and the uniformity of that totally echoed the uniformity of the prison environment,” he said to me, “where I had my cell and my seven feet of wall and then a door. And I remember thinking, ‘Oh my God, man.'” He laughed at the utter despair of it all, having gone from one system of containment to another. How would you get away or escape from this?

This is a common image of suburbs: prisons of conformity and tedium, laid out every twenty-five feet by developers to maximize profits while misguided Americans snap up the properties thinking they have found the American Dream. Yet, sameness in lot size doesn’t necessarily mean sameness in lives. These regular spacing could be a very good sign of a tract neighborhood but even then, the homes – like those in Levittown over the decades – could be altered as various owners put their own mark on the dwellings. Or, the neighborhood could be quite diverse, particularly in older suburbs.

Additionally, prisons are built with very different purposes in mind compared to suburbs. Developers and local officials are not scheming to control people in these homes (except maybe through a capitalistic system that keeps them focused on their own properties and blinded from larger issues). In contrast, prisons are all about surveillance – just think of Bentham’s Panopticon.

“Forty Percent of the Buildings in Manhattan Could Not Be Built Today”

Manhattan’s zoning code is complicated and there are a number of buildings – many built prior to 1930 – that would not meet current standards:

New York City’s zoning code turns 100 this year. That may not sound like cause for celebration — except maybe for land-use lawyers and Robert Moses aficionados. Yet for almost every New Yorker, the zoning code plays an outsize role in daily life, shaping virtually every inch of the city…

New York’s zoning code was the first in the country, meant to promote a healthier city, which was then filling with filthy tenements and office towers. Since it was approved in 1916, the ever-evolving, byzantine code has changed many times to suit the needs of a swollen metropolis. Just in March, the administration of Mayor Bill de Blasio won approval for a vast citywide plan that would encourage sleeker, more affordable developments…

Mr. Smith and Mr. Trivedi evaluated public records on more than 43,000 buildings and discovered that about 17,000 of them, or 40 percent, do not conform to at least one part of the current zoning code. The reasons are varied. Some of the buildings have too much residential area, too much commercial space, too many dwelling units or too few parking spaces; some are simply too tall. These are buildings that could not be built today…

Nearly three-quarters of the existing square footage in Manhattan was built between the 1900s and 1930s, according to an analysis done by KPF, an architecture firm based in New York. In a way, the zoning code helps to preserve such architectural diversity. The laws have gotten more restrictive over time, giving an edge to properties built in earlier eras.

Three quick thoughts:

  1. I particularly like the two examples of buildings cited in the story where it is clearly shown what would have to change should the buildings be subject to current standards.
  2. It is not entirely clear but it looks like this article credits zoning for protecting a lot of these older buildings. If you wanted to purchase an older building, tear it down, and build a new one, the new structure would not be quite the same. This means that zoning acts as a kind of historic preservation. Of course, we could ask how many older buildings are too many?
  3. There are calls to overhaul the zoning code to make it simpler. One of the problems is that different areas of Manhattan want different standards. Even though New York City the global city, many of the building decisions are local and residents want some control. Think of Jane Jacobs’ efforts to save Greenwich Village and certain structures during the 1960s. A more vanilla zoning code would make things simpler but could hinder local character.

China introduces plan to eliminate gated communities

Gated communities may be popular in the United States and many other countries but China is looking to open them up:

Along with its ambitions to finally put an end to “weird” architecture, China is also hoping to ban gated communities. In the same directive that called for stricter building standards, the State Council of the People’s Republic of China has also recommended that future residential enclaves be opened to the public. Existing gated communities would also gradually have their once-private streets integrated into the public road network. Not only would the move ease traffic congestion, the government argues, but it would also make better use of land.

But that particular part of the plan has drawn criticism from legal experts and fierce opposition from the public. Lawyers say such a mandate infringes on residents’ property rights, which according to China’s property laws, are “inviolable.” According to the South China Morning Post, the cost of roads and other shared spaces inside gated communities are factored into the price of residents’ homes, so they are essentially considered private property. China’s Supreme Court recently told the Hong Kong newspaper that they will be “paying close attention” to the directive.

Is this a microcosm of a larger debate between a more free market economic system versus more government control? The question of whether developers can build and residents, particularly those who feel they have joined the middle or upper class, can move into gated communities seems tied to a number of bigger issues.

I’m reminded that one tool of power available to governments is to dictate use of land and regulate architecture. Americans tend to prioritize property rights but the United States has a variety of land and architecture regulations, particularly zoning at a local level as well as historic preservation districts. Less frequent is the use of eminent domain, though it has been used regularly in the past for urban renewal which was often about taking land and profiting from new development. See the recent case in Chicago where Mayor Rahm Emanuel has discussed seizing the old post office building to make money for the city.

So how far should governments go regarding regulating land and architecture? A completely free market system would lead to some negative outcomes but too much implies tyranny.

Regulating sex businesses in the suburbs

Many suburbs want nothing to do with strip clubs and similar businesses so they employ several methods to discourage them:

Warren is running into something that has plagued businesses dealing in sex for decades. Local governments — and the officials elected to govern them — don’t want these businesses around, according to Judith Hanna, a professor at the University of Maryland.

Hanna has testified as an expert witness in more than 150 court cases involving sexually oriented businesses. She even wrote a book about her experiences…

The majority of the cases she testified for involve strip clubs, which Supreme Court rulings protect because of First Amendment rights…

Menelaos Triantafillou, a professor at the University of Cincinnati who teaches courses in planning and urban design, explains: “The only thing you can regulate is not the use itself,” he said, “but the specific location.”

Local governments typically allow these businesses to exist in industrial areas. Restrictions are placed on how close they can be to other establishments such as schools and day cares.

In the particular case discussed in this article, the community is working hard to make a swingers club go away. But, it sounds like they are making it up as they go to appease voters as several local officials have privately supported the new business.

Perhaps an alternative strategy is in order. Zoning is a big deal in suburbs as they get to keep uses that limit endanger property values or a high quality of life away from single-family homes. But, zoning can only do so much. Yet, communities can make it clear that certain businesses are not welcome. While suburbs often welcome new businesses (they provide jobs, property tax revenue, perhaps sales tax revenue), couldn’t they also make it hard for the new business to make money? I’m thinking bad publicity, protests, no invitations to the local chamber of commerce and local events.

Proposing a stronger theory of NIMBYism

A lawyer in Austin is working on a more-encompassing theory of explaining NIMBY responses to development:

The key to any strong definition or explanation, suggests Bradford, is that it must go beyond the simplistic idea that NIMBYism aims to protect home value, full stop. If that’s the case, why do some homeowners reject development projects so forcefully while others don’t? Why is California more NIMBY than Texas, for instance, or Austin more NIMBY than Houston? Why is NIMBYism more intense now than it was 40 years ago, when home value mattered just as much to personal wealth?

Bradford builds his own central thesis around the idea that NIMBYs seek to monopolize “access to neighborhood amenities”:

“In the absence of zoning restrictions on the number of housing units in a neighborhood, neighborhood amenities would be a public good. Zoning converts neighborhood amenities from a public good (a partially non-rivalrous, non-excludable good) into a “club” good (a partially non-rivalrous, excludable good). Because “club” membership is bundled with home ownership, zoning causes the value of neighborhood amenities to be capitalized into home prices. NIMBYism can be thought of as the practice of objecting to development in order to protect the value of “club” membership.”…

As for realistic policy solutions, Bradford makes an initial go at these, too. Rather than trying to undo existing single-family zones, he says, an easier place to start would be for local planners and officials to stop automatically applying such zoning to new developments. “There is no particular constituency for zoning fringe greenfields exclusively for single-family use, so cities ought to stop doing it,” he writes. “This practice merely begets the next generation of NIMBYs.”

It sounds like the argument is that property values are part of a deeper desire to protect the neighborhood from use by others. People buy a property with the expectation that they will have exclusive use of particular features, whether that is parks, roads with less traffic, or nearby open spaces.

The policy solution offered above is intriguing. If buyers don’t have any knowledge of how the land nearby might be used, it lowers their expectations about what might be there some day. Still, they might object to any changes – home buyers on the fringe become quite enamored with empty fields. Additionally, this recommendation doesn’t help deal with infill or redevelopment situations.

I wonder if some developer could up the value of their properties by writing into the deed or through some other contract that the land nearby will not change for a certain number of years. Would buyers be willing to pay a premium if that land was controlled and they knew they had exclusive rights to amenities? If a developer couldn’t be sure of the actions of a municipality, perhaps they could purchase a buffer zone that they would control.

Chicago set to expand TOD boundaries

The City of Chicago wants to expand the area that would be eligible for transit-oriented development guidelines:

According to the Tribune, the mayor is expected to introduce a reform that would allow developers to build new TODs within 1,320 feet of a transit station—which would more than double the surface area that developers could build within. In addition, the new rules would also allow developers to build TODs within 2,640 feet of designated pedestrian streets.

Here is a bit more on the background:

Generally, the city requires that developers include one vehicle parking space per residential unit, however the TOD ordinance allows developers to cut down their parking requirements by at least half if the project is located 600 feet from a transit station…The mayor believes that the big investment in renovating the CTA stations along the Brown, Red and Blue lines will serve as a catalyst to seeing more transit-oriented developments, and wants to expand the constraints that developers currently have to build within. “This ordinance will capitalize these investments by accelerating development near transit stations,” the mayor recently declared.

This may not sound like much – the TOD boundaries increase from 600 to 1,320 feet from the transit station – but it could have quite an impact in certain neighborhoods:

[Pretty much everything would be on-limits in the West Loop, River West and River
North neighborhoods if the changes are made.]

The average citizen may not pay much attention to such things but zoning and land regulations have a lot of influence on urban patterns. This change could provide more incentive for denser developments around transportation nodes.

It would be interesting to hear Emanuel’s justification for this: is this about capitalizing on developers who really want to build in these places? Is it about going green? Is it about cutting down on traffic?
