A brief refresher: single-family zoning (also known as "R1" in planning language) prohibits a community from constructing any sort of dwelling in a specific area other than a detached single-family house. It's almost universal in the suburbs, but it's also an issue in the city. The goal is to prevent overcrowding and maintain enough space so that each household has enough room for a lawn and a driveway.
It all started in the 1920s when people were moving away from cities and into the suburbs. At first, there were only single-family houses, which were fine for now, but as time went on, more families needed places to live. So, municipal officials decided to limit what could be built in these areas to avoid having too many people live in small spaces.
The problem with this approach is that it doesn't take advantage of advances in design or construction technology. If we knew then what we know now about home building today, would we still want to limit housing options like this? Most likely not, but that's how zoning laws work - they're stuck in the past with no idea what the future will bring.
In conclusion, single-family zoning is in place to make sure that you don't build too many houses in one area. This prevents overcrowding and ensures that enough space is left over for yards and driveways.
Single-family dwellings can still be built. One of the most prevalent justifications for maintaining single-family zoning is that most people prefer single-family houses. As seen by the premiums found in walkable urban districts, this is no longer the case, as studies demonstrate a demand for denser living even in car-friendly locations.
The need for more space than what is allowed in most single-family zones has been met by creating "mansion neighborhoods". These are usually located near major cities with strong economic growth and are designed with wide streets and large yards. They are often gated communities with security guards and limited access. These neighborhoods tend to be expensive to build because of the size of lot required by city regulations. If these neighborhoods were allowed in place of multiple family units they could increase the supply of housing while keeping prices low.
Other ways to provide for this need include building higher density apartment buildings or townhouses, but there are limits to how high you can build in most areas. Also, if you build too many such buildings they will start to look like a ghetto and property values will decline.
Finally, you can also buy land in these neighborhoods and build a house on it yourself. The cost of land in these neighborhoods is generally much higher than other areas so this option is only available to those who can afford it.
In summary, there is overwhelming evidence that single-family zoning has harmed the environment by increasing suburban expansion and automobile use, harmed affordability by limiting housing supply, and harmed inclusion by keeping low-income households out of high-opportunity communities. All things considered, do you believe that single-family zoning benefits or harms the environment? Why?
Single-family zoning affects the environment in different ways depending on the type of zoning used in a community. Neighborhoods with small residential blocks are thought to be more walkable and less prone to traffic problems than large expanses of land separated by only a street wall. Therefore, single-family neighborhoods are assumed to be better for the environment than larger scale development models. However'take away cars from the streets and you take away one source of pollution. ' In order to reduce auto usage in single-family neighborhoods, people need easy access to public transportation. However, this type of zoning limits the amount of land available for developing mass transit lines which would be needed if many areas wanted to reduce their reliance on automobiles.
There are several studies that have looked at the environmental impacts of different development types over large regions. One study conducted by David Favaro of Penn State University found that single-family neighborhoods tended to have smaller environmental impacts than other types of development. The study concluded that neighborhood zoning was responsible for most of the difference between average household incomes in developed countries and poor economies like Haiti's.
