California's Housing Reforms: Early Results & Unintended Consequences
Locales: California, UNITED STATES

Sacramento, CA - February 15th, 2026 - California's ambitious attempt to tackle its decades-long housing crisis is entering a new phase. Following the implementation of Senate Bills 9 and 10 in 2022, the state is beginning to see the tangible effects - and facing the unforeseen consequences - of its dramatic overhaul of single-family zoning regulations. While proponents hail the changes as a necessary step toward affordability and increased housing stock, critics voice concerns about neighborhood character, infrastructure strain, and potential displacement of long-term residents.
For years, California has struggled with a severe shortage of housing, driving up prices and forcing many residents to leave the state or endure lengthy commutes. Traditional zoning laws, which largely restricted development to single-family homes on large lots, were identified as a major impediment to addressing the problem. SB 9, which took effect in 2022, allowed homeowners in many areas to build duplexes, triplexes, or fourplexes on lots previously reserved for a single-family dwelling. SB 10 went further, enabling cities to upzone areas near transit and employment centers, potentially allowing for the construction of multi-family buildings.
The initial goal was simple: increase housing density. Early data from cities across the state suggest that the legislation is, in fact, achieving that. Building permit applications for ADUs (Accessory Dwelling Units) and JADUs (Junior Accessory Dwelling Units) surged immediately after the bills were signed into law, and that trend has continued. Cities like Los Angeles, San Francisco, and San Diego are reporting a noticeable increase in smaller-scale, multi-family developments.
However, the reality on the ground is far more complex than simple supply and demand. While increased density is occurring, the types of housing being built are not necessarily affordable for the majority of Californians struggling with housing costs. Much of the new construction falls into the middle or upper-middle-income brackets, doing little to alleviate the burden on low-income families. Critics argue that the laws primarily benefit homeowners who can afford to build ADUs or subdivide their lots, creating a windfall for some while doing little to address the core affordability issues.
Furthermore, concerns about neighborhood character are proving to be valid. In some communities, the rapid influx of new, denser housing has led to increased traffic congestion, parking shortages, and strains on existing infrastructure like water and sewer systems. Some residents also express concern about the loss of green space and the changing aesthetic of their neighborhoods.
Perhaps the most pressing issue, however, is the potential for displacement. While tenant protections exist, they are not always sufficient to prevent landlords from evicting renters in order to build ADUs or redevelop properties. Advocates for affordable housing are calling for stronger tenant protections and increased funding for rental assistance programs to mitigate the risk of displacement. They point to instances where "renovictions" - evictions disguised as renovations - are being used to push out long-term residents.
The state government is now grappling with these unintended consequences. A series of legislative hearings were held last month to discuss potential amendments to SB 9 and SB 10. Proposed changes include increased funding for infrastructure improvements, stricter regulations on ADU construction, and expanded tenant protections. There's also discussion around incentivizing the construction of truly affordable housing through tax credits and density bonuses.
"We knew this was going to be a complex undertaking," stated Assemblymember David Chiu, a key sponsor of SB 9, during a recent interview. "We anticipated some challenges, but the scale of the infrastructure strain and the potential for displacement are concerning. We are committed to working with cities and community groups to find solutions that ensure this policy benefits all Californians."
The next few years will be crucial in determining whether California's zoning reforms can truly address the housing crisis without sacrificing the quality of life for existing residents. The balance between increasing density, preserving neighborhood character, and protecting vulnerable populations remains a delicate one, and the state is walking a tightrope between innovation and disruption.
