Each decade of exclusionary zoning is associated with an average increase in monthly median rent of $24-27 in impoverished neighborhoods, according to Eviction Lab. An incremental rise in monthly median rent of $24-27 accumulates over time, placing significant financial strain on households already struggling with limited resources. Furthermore, each decade of such zoning also correlates with an estimated one percentage point increase in the share of renting households experiencing rent burden in these same communities.
Zoning is often presented as a tool for orderly community development, guiding where homes, businesses, and industries can be built. However, it frequently restricts housing supply, which drives up costs and reinforces social segregation. The restriction of housing supply, which drives up costs and reinforces social segregation, creates a challenging environment for those seeking stable, affordable housing.
Based on historical and economic evidence, current zoning practices will likely continue to exacerbate housing crises and deepen societal divides. Significant reforms promoting density and inclusivity must be widely adopted to counter these trends.
What Zoning Is, and How It Shapes Our Cities
Zoning ordinances are local laws that regulate how land can be used in specific areas, directly influencing urban development. These regulations dictate everything from building height and density to the types of structures permitted on a parcel of land. By limiting the number and kind of homes that can be built, zoning directly impacts the availability of housing.
These zoning and land use regulations restrict housing supply, which can drive up housing prices when demand is high, according to PMC. For instance, areas zoned exclusively for single-family homes prevent the construction of multi-unit dwellings. This restriction inevitably leads to fewer available homes, increasing competition and costs for potential buyers and renters in 2026.
The restriction of housing supply by seemingly bureaucratic land-use rules has direct, measurable impacts on the financial stability of residents, especially those in vulnerable economic positions. The scarcity created by restrictive zoning contributes significantly to wealth disparities within communities.
