News Summary
California faces a severe housing shortage, with a projected increase of only 0.84% in new housing stock for 2024. Accessory Dwelling Units (ADUs) are a significant contributor to this growth, accounting for one-fifth of new constructions. However, many owners choose not to rent these units out, which limits their effectiveness in addressing the housing crisis. While legislative efforts aim to streamline ADU construction, rising costs pose challenges for homeowners. The effectiveness of ADUs in providing affordable housing remains under scrutiny as California continues to grapple with its persistent housing shortage.
California is grappling with a significant housing shortage, with new housing stock projected to increase by only 0.84% in 2024. This translates to approximately 125,000 housing units, a number that falls short of meeting the state’s growing demands. A notable contributor to the increase in new housing units is Accessory Dwelling Units (ADUs), which accounted for about one-fifth of these new constructions.
The construction of ADUs is experiencing a boom in various regions across California as homeowners construct additional units on their properties. These units are often seen as valuable investments, potentially increasing the property value. However, building an ADU can be costly, with expenses typically ranging in the hundreds of thousands of dollars.
Despite the increase in ADUs, many owners are opting not to rent these units out. Instead, they often use them to house family members or leave them vacant, which complicates their effectiveness in alleviating the ongoing housing shortage. In San Diego County, for instance, 85% of permitted ADUs are occupied by renters, leaving only 15% utilized by the owners themselves.
Eric McGhee from the Public Policy Institute of California notes the uncertainty surrounding the role of ADUs in the housing crisis. It remains unclear whether these units provide housing for people who would otherwise lack accommodation or if they merely offer additional living space for existing residents. In data reflecting production, ADUs saw a notable increase of 14.3% in 2024 compared to the previous year, which followed a 10% growth in 2023.
The city of Los Angeles stands out with a 6% increase in housing stock from 2020 to 2025, establishing itself as one of the leading cities for housing growth within Los Angeles County. Nevertheless, growth rates vary significantly across the state. For example, Madera County experienced a 2.7% increase in housing stock in 2024, while smaller cities like Huron reported growth rates nearing 8%.
Los Angeles County has permitted more ADUs per capita than any other county in California, with a noticeable trend showing that lower- and middle-income cities are approving more ADU constructions. Research conducted by UCLA indicates a higher prevalence of ADUs in areas that are lower income, have denser populations, and are occupied predominantly by younger renters.
Amid legislative pushes to enhance ADU construction, the challenges posed by rising construction costs continue to make ADUs less viable as a comprehensive solution to the housing crisis. Recent state laws have been enacted to ease the regulatory framework around ADU construction. These changes include reduced parking requirements and a streamlined approval process, aimed at expediting the construction of these units.
Costs associated with constructing ADUs can vary broadly across California. Fees can reach upwards of $26,000 depending on the ADU’s size and location, further complicating the financial feasibility for many homeowners. In response to these challenges, a bipartisan federal bill called the SUPPLY Act has been introduced, aiming to provide financing options for homeowners wanting to build ADUs. This proposed legislation strives to facilitate participation in ADU development, especially for modest-income families.
As California navigates its persistent housing shortage, the role of ADUs continues to emerge as both a potential solution and a subject of scrutiny. While they contribute to new housing stock, the effectiveness of ADUs in addressing the state’s pressing need for affordable housing remains to be fully realized.
