A more diversified housing landscape may soon be coming to California as state leaders implement aggressive new strategies to tackle an enduring affordability crisis. Governor Gavin Newsom signed a comprehensive package of housing legislation designed to slash bureaucratic red tape, incentivize residential construction, and accelerate overall housing production across the state. The newly enacted laws aim to reshape communities by clearing the path for a wider variety of housing options, ranging from towering residential high-rises in major urban transit hubs to townhomes, condominiums, and accessory dwelling units tucked away in suburban backyards.
The legislative push arrives as California continues to grapple with severe housing scarcity and some of the highest real estate prices in the nation. According to a 2024 Zoning Atlas analysis, more than 95% of all residential land area in California is strictly zoned for single-family housing only. This restrictive zoning legacy, combined with rapid job growth and historically sluggish housing production, has driven homeownership out of reach for millions of residents and contributed to the largest unhoused population in the United States.
Supporters of the legislative package argue that systemic changes are long overdue to address the root causes of the state’s housing and homelessness emergencies. While California has recorded recent steps forward in reducing its unhoused population—including a modest 2.8% decline in 2025—state officials emphasize that sustained progress depends entirely on building significantly more homes at every price point.
"Every Californian deserves a fair shot at a stable home—families shouldn’t have to wait years for housing to be approved and built in their communities," Governor Newsom said in an official news release following the bill signings. By streamlining approvals and limiting the ability of local jurisdictions to block multi-family developments, the state hopes to shift the momentum toward a more inclusive and productive housing market.
Finding the Missing Middle
For decades, housing development in California has largely been bifurcated into two extremes: detached single-family houses and large multi-family apartment complexes. This polarization has created a severe shortage of what urban planners call "missing middle" housing—duplexes, triplexes, townhomes, and courtyard apartments that offer affordable pathways to homeownership for working families and middle-class buyers. As a growing number of states explore middle-scale housing types to combat widespread affordability pressures, California is moving aggressively to mandate and encourage these developments.
Chief among these efforts is the Missing Middle Townhome Act, designated as AB 1751. The legislation establishes a streamlined, by-right approval pathway for townhome development projects of up to 150 units. Furthermore, it authorizes local governments to establish a fast-track, 60-day ministerial approval timeline for qualifying projects, according to a legislative analysis by the law firm Holland and Knight. Crucially, the legislation also exempts these much-needed townhome developments from lengthy and often litigious reviews under the California Environmental Quality Act, a frequent bottleneck for residential builders.
To complement these measures, a separate piece of legislation, SB 1116, strengthens the state’s existing Starter Home Revitalization Act, building upon previous frameworks established by SB 684 and SB 1123. According to analysis from the advocacy organization California YIMBY, the new law clears a clear, dependable path for a 60-day approval process for starter homes, including both townhomes and condominiums. Additionally, SB 1116 explicitly blocks local governments from using subjective zoning standards and local ordinances to block or restrict these types of attainable housing developments in certain residential zones.
Bigger Smaller Housing
While mid-scale housing developments promise to transform neighborhoods across the state, smaller secondary residential structures have already experienced a remarkable surge in popularity. California has witnessed a massive boom in the construction of accessory dwelling units, commonly known as ADUs or backyard cottages, as homeowners seek ways to generate rental income, accommodate aging relatives, or house adult children.
However, high development costs, particularly local impact fees charged per square foot, have historically posed a financial hurdle for property owners wanting to build slightly larger, family-sized ADUs. The new legislation signed by Governor Newsom addresses this specific barrier by eliminating the full impact fee for ADUs that exceed 750 square feet. Under the updated regulatory framework, local governments are now restricted to a marginal fee structure. Instead of charging full impact fees across every single square foot of a larger structure, municipalities can only charge proportionally for the square footage that exceeds the 750-square-foot threshold for the first two ADUs built on a single property.
Housing advocates and policy experts have praised the change as a vital step toward making secondary units more practical for growing families. Eliminating the prior fee structure substantially reduces upfront construction costs, providing a tangible incentive for homeowners to invest in larger secondary dwellings. Brian Hanlon, CEO of California YIMBY, noted in a press release that the reform represents a substantive change that will directly facilitate the creation of more family-sized accessory dwelling units throughout the state’s sprawling residential neighborhoods.
A Highway to High-Rises
While backyard cottages and townhomes address suburban and mid-density neighborhoods, urban cores face a different set of challenges that require high-density solutions. Many of California’s downtown commercial districts have struggled to recover fully in the post-pandemic economic landscape, leading state lawmakers to look at transit-oriented development as a dual solution for economic revitalization and housing production.
Under AB 2074, seven of the state’s largest and most transit-rich cities are now required to establish designated regional transit hub districts. Within these defined areas—which must encompass at least one major transit-oriented development stop—cities are legally required to set residential building height limits to a maximum of at least 150 feet. More dramatically, the law mandates that residential buildings with a maximum height of at least 450 feet must be permitted in at least 25% of all regional transit hub districts within a qualifying city.
The legislation aims to harness existing public investments in light rail, subways, and commuter rail networks by channeling dense residential growth directly to areas where residents can easily commute without relying on automobiles. Proponents argue this approach targets housing construction precisely where demand is highest while simultaneously stimulating local economies.
"Our downtowns are still struggling and need to be brought back to life," said Assemblymember Matt Haney, the primary sponsor of the bill, in a press statement released earlier this year. "AB 2074 makes that happen by building dense housing where it’s needed most while creating good-paying jobs."
As these diverse housing reforms take effect, municipal planners, developers, and local officials across California are preparing for a profound shift in how residential communities are built and regulated. Whether the combination of streamlined townhome approvals, reduced ADU fees, and high-rise transit corridors can successfully overcome the state’s historic housing deficit will depend heavily on local implementation in the months and years ahead.
