Zoning regulations govern what kinds of businesses and homes may be built where. Their purpose is to protect residents from potential hazards while upholding aesthetics and limiting conflicts.
Some outdated zoning rules, like a 1961 regulation that restricted Woolworth’s or drugstores from opening in retail districts, no longer meet planning objectives. Others, like mandating parking in transit-served areas, can discourage business investment.
Acreage
Before purchasing property zoned for residential or commercial use, it’s essential that you understand its zoning. Zoning regulations dictate what kinds of structures can be built on a piece of land as well as their height and location; additionally, they help preserve environmental resources as well as historic or culturally significant sites.
Most jurisdictions provide various kinds of zoning regulations, from industrial and commercial zoning, through residential to “aesthetic” zones that regulate paint colors and building materials.
Pendergast notes the complexity of local zoning laws can be daunting: “[They are] like Russian nesting dolls of regulations.” To gain an overview, start with city or neighborhood ordinances before moving on to county and state regulations.
Uses
Zoning ordinances govern how property can be utilized. These regulations may include restrictions on size, density and location as well as specific requirements like parking spaces, green space or height limits.
Residential zoning laws tend to limit construction to buildings designed for human occupancy, such as single-family homes, apartments and condos. Furthermore, certain businesses that generate too much noise or traffic may also be barred.
Experts contend that zoning laws can be used to foster economic segregation. Restrictions such as large lot sizes and housing requirements often prevent low-income residents from moving into desirable neighborhoods with good schools and nearness to jobs – leading them into less desirable properties, lower property values, reduced safety and morale, as well as creating feelings of isolation among those without the means to relocate.
Density
Density regulations place restrictions on the number of people or businesses allowed per acre, while also setting regulations regarding building height, size and proximity between structures. Such regulations help ensure a city remains safe and functional for both its inhabitants and visitors alike.
Companies that would disrupt residential neighborhoods from opening nearby can also be prevented. For instance, drive-thru windows at restaurants may create too much noise and traffic disruptions for nearby apartments.
Modern zoning reforms seek to make neighborhoods more walkable, supporting sustainability efforts while decreasing financial and environmental costs associated with car ownership. Furthermore, such initiatives may improve access to jobs, schools, and amenities for residents.
Height
Zoning regulations set restrictions on how tall and for what purpose a building may stand. While residential, commercial, and industrial zoning districts exist in most cities, subcategories also regulate specific aspects of development like floor area ratio, lot coverage, and height regulation.
As such, it’s vitally important that you review your local zoning ordinances in detail to understand what each symbol or letter-number combination indicates for any particular parcel – this way you’ll avoid building factories in your backyard or skyscrapers far from transit lines.
Most zoning ordinances were created to prevent commercial encroachment into residential neighborhoods. Incentive zoning policies offer greater density in exchange for contributions made back to the community, such as affordable housing or transportation infrastructure upgrades – these serve as an ideal alternative to exclusionary policies such as New York City’s 1916 Zoning Resolution.
Setbacks
As soon as a home or building is constructed, it must adhere to setback regulations, which determine how far away from street-facing property lines it must stand. This ensures a certain amount of privacy as well as sufficient space for fire access, maintenance services and utility services.
These regulations vary based on your city and neighborhood; to understand any restrictions in effect, it’s wise to contact your local government for guidance.
Many critics point to zoning regulations as contributing to America’s housing crisis. Traditional applications of zoning laws tend to geographically isolate residential neighborhoods from places where people work and play, leaving residents reliant on cars for transportation costs that are increasingly high. New urbanist planning and design advocates favor integrated, walkable neighborhoods with less stringent zoning regulations.
