    What is Zoning Code?

    Zoning codes have shaped major U.S. cities for over a century, serving as the backbone of urban development by defining the permissible land uses and activities within neighborhoods. Zoning regulations enable cities to exercise control over the use and development of land, establishing clear guidelines for commercial, industrial, residential, and agricultural purposes. Essentially, zoning determines the possibilities and limitations for construction on a property.

    How does Zoning Impact Real Estate Values?

    Zoning plays a pivotal role in the entire lifecycle of a home and significantly influences various stages. Extensive research conducted by Zillow has underscored the importance of zoning regulations, showing their impact on home values. According to Zillow Research, housing markets with stricter land use regulations experienced the highest growth in home values. In fact, the most restrictive metropolitan areas witnessed an average appreciation of 23.4%, more than double that of the least restrictive metros. It's worth noting that zoning regulations are determined locally, and different cities may have varying degrees of restrictiveness. Furthermore, even within a city's zoning system, individual zones can vary in their level of restrictions, including different types of single-family zones.
