In recent years, cities across the United States have been reevaluating their zoning laws to address housing shortages and promote affordability. Traditional single-family zoning, which restricts development to detached homes, has been identified as a barrier to increasing housing density and diversity. For instance, in 2018, Minneapolis became the first major U.S. city to eliminate single-family zoning, allowing duplexes and triplexes in all residential neighborhoods. This move aimed to provide more affordable housing options and reduce racial inequities associated with housing segregation. en.wikipedia.org
Similarly, in 2021, California's Senate Bill 9 (SB 9) was enacted, enabling homeowners in single-family zones to build up to four units on their properties. This legislation sought to streamline housing development and increase density in areas with high demand. Additionally, the Abundant and Affordable Homes Near Transit Act (SB 79), introduced in January 2025, proposed upzoning areas near transit stations to allow for taller residential buildings, further promoting density and affordability. en.wikipedia.org
To adapt to these zoning changes, homeowners can explore opportunities to add accessory dwelling units (ADUs) or convert existing spaces into rental units, providing additional income and contributing to housing availability. Utilizing online platforms and local resources can assist in navigating the permitting process and ensuring compliance with new regulations.
