A Brief Guide to Zoning
What Exactly is Zoning?
It’s a popular topic here at Civic Capacity, and local government agendas are often filled with these issues, but it’s a subject that many people may not have a deep understanding; it’s zoning. Many individuals are left wondering about how zoning works and how does it benefit a community. Today, our publication is dedicated to give some important background on what zoning is and what it might look like in the future.
Zoning is a crucial tool used by local governments to regulate land use and development within their boundaries. In Ohio, municipalities, counties and townships are all permitted to create and enforce their own zoning codes. And while the concept of zoning is universal, it’s important to realize that no two zoning codes are alike.
At its core, zoning divides a city or town into different districts (or zones), each with specific rules about how land can be used and what types of buildings can be constructed. This system helps create organized, functional communities by separating incompatible land uses and promoting harmonious development.
The concept of zoning emerged in the early 20th century as cities grew rapidly and conflicts arose between different land uses. Before zoning, it was not uncommon to find factories next to homes or noisy businesses in quiet residential areas. This haphazard development often led to health and safety issues, decreased property values, and a lower quality of life for residents.
The legal foundation for modern zoning in the United States was established by the landmark Supreme Court case Village of Euclid v. Ambler Realty Co. in 1926. This case upheld the constitutionality of zoning ordinances, recognizing them as a valid exercise of a municipality's police power to protect public health, safety, and welfare. The Court's decision paved the way for widespread adoption of zoning regulations across the country.
Today, most cities and towns have comprehensive zoning codes that divide the municipality into various districts. Common zoning categories include residential, commercial, industrial, agricultural and mixed-use. Within these broad categories, there are often subcategories that further refine allowed uses. For example, residential zones might be divided into single-family, multi-family, and high-density residential areas. Here in Troy, the R-1, Single-Family Residential district has larger lot sizes than the R-2, Single-Family Residential district; as a rule of thumb, the larger the number, the smaller the lot size.
Zoning regulations typically specify a range of factors for each district. These may include permitted land uses, building height limits, setbacks from property lines, lot sizes, and parking requirements. Some zoning codes also address aesthetic considerations, such as building materials or architectural styles, particularly in historic districts or areas with distinct character.
One of the primary benefits of zoning is its ability to separate incompatible land uses. By keeping industrial activities away from residential areas, for instance, zoning helps protect homeowners from noise, pollution, and heavy traffic. It also allows for more efficient urban planning by clustering similar uses together, which can improve transportation systems and the delivery of public services.
Zoning also plays a crucial role in shaping the character and feel of neighborhoods. By regulating factors like building height and density, zoning can preserve the low-rise, spacious nature of suburban areas or encourage the development of bustling, walkable urban centers. This ability to influence community character makes zoning a powerful tool for implementing a city's long-term vision and goals.
However, zoning is not without its critics. Some argue that strict zoning regulations can lead to urban sprawl, housing shortages, and increased segregation. In recent years, there has been a push in many cities to adopt more flexible zoning approaches that allow for greater mixing of uses and housing types, such as allowing accessory dwelling units. This trend reflects changing attitudes about urban living and a desire for more diverse, vibrant neighborhoods.
The legal landscape of zoning has continued to evolve since the Euclid decision. Subsequent court cases have addressed issues such as exclusionary zoning, religious land use, and environmental protection. For example, the Fair Housing Act of 1968 prohibits zoning practices that discriminate against protected classes, while the Religious Land Use and Institutionalized Persons Act of 2000 provides special protections for religious institutions in zoning matters.
Zoning ordinances must also comply with constitutional protections, particularly those related to property rights. The Fifth Amendment's Takings Clause requires that property owners be compensated if government regulations, including zoning, deprive them of all economically viable use of their land. This principle has led to ongoing legal debates about the balance between public interests and private property rights in zoning decisions.
In practice, zoning is implemented through a combination of maps and written regulations. Zoning maps visually depict the various districts within a municipality, while the zoning text provides detailed rules for each district. Changes to zoning, known as rezoning or zoning amendments, is a legislative process on the local level, requiring a recommendation from a local planning or zoning commission, public hearings and public notices, and a final decision by the local governing board.
Many municipalities also use special zoning tools to address specific planning goals or unique situations. Overlay districts, for instance, add additional regulations on top of existing zoning districts, often to protect natural resources or retain certain types of neighborhood characteristics, such as a historic overlay district. Also, common in zoning codes are Planned Unit Developments (PUDs) that allow for more flexible, integrated designs that might not fit neatly into standard zoning categories.
As communities face new challenges related to transportation, affordable housing, and changing demographics, zoning continues to evolve. Form-based codes, which focus on the physical form of buildings rather than specific uses, are gaining popularity as a way to create more adaptable, mixed-use neighborhoods; the recently enacted zoning code in Piqua would be an example of a form-based code. Some cities are also experimenting with zoning incentives to encourage sustainable development or the provision of affordable housing.
It is important to realize zoning is a complex and dynamic system that plays a vital role in shaping our communities. While its primary purpose remains the separation of incompatible land uses, modern zoning has become a sophisticated tool for implementing broader urban planning goals. As our communities continue to grow and change, zoning will undoubtedly remain a powerful tool to create livable and sustainable hometowns.
