Short Summary
A deep dive into Sonoma County’s housing crisis and the community-led policy solutions being proposed to address it.
Long Summary
You listened to a presentation by Generation Housing on the state of the housing crisis in Sonoma County. The discussion highlighted a shortage of over 50,000 homes, which impacts everyone from young families to seniors, leading to school closures and workforce challenges. The event launched the ‘Housing for Healthy Communities’ initiative, focusing on state laws to encourage building more ‘missing middle’ housing and creating starter homes. The central theme was that a broad, community-wide advocacy effort is essential for creating meaningful change.
2025 State of Housing Report
The report focuses on telling a housing story using data to address successes, myths, and the intersectional nature of housing. There is a significant housing shortage at all income levels, particularly for affordable housing. The crisis is defined by the impact of this shortage on education, health, the economy, and the climate. The housing shortage is the result of 75 years of policy, requiring a multi-faceted approach (“silver buckshot”) rather than a single solution.
Housing & Community Impact
A panel of experts shared how the housing crisis affects various sectors of the community. Youth & Families: Sonoma County is losing homegrown talent as young people, including recent graduates and community leaders, are forced to leave due to high living costs. Education System: Teachers and school staff cannot afford to live in the community, leading to high turnover and negatively impacting student success. This has contributed to declining enrollment and school closures.
Workforce & Young Adults: The lack of affordable rental options is a “missing rung on the ladder” to homeownership, causing young adults to delay forming independent households or leave the area.
Seniors & Caregivers: Seniors on fixed incomes, even homeowners, face extreme cost burdens from rising insurance and utility costs. The caregivers they depend on are also priced out of the region, threatening seniors’ ability to age in place with dignity. Immigrant Community: Immigrants and foreign-born residents face immense barriers to housing stability, with homeownership often taking over 25 years to achieve. Housing policy needs to center the humanity of these community members.
Permanent Supportive Housing: This model is the most effective way to end homelessness but is very expensive to operate. Housing Choice Vouchers, which cap a resident’s rent at 30% of their income, are essential for the financial viability of these projects.
Benefits of Affordable Housing: A Napa County study revealed that the greatest benefits of affordable housing were social and economic stability, stress reduction, and the ability for residents to engage in long-term financial planning, such as saving for a home down payment.
Calculating Sonoma County’s Housing Need
The established goal is to build approximately 58,000 new homes by 2030. This number was validated through three independent methods that all produced similar results: Household Formation Deficit: A historical deficit of 38,000 households that should have formed, plus a
future need for 20,000 more. Property Value Method: The number of homes needed to bring the disproportionately high cost of land back to a normal market rate. Vacancy Rate Method: The number of homes needed to achieve a healthy 5% vacancy rate, as Sonoma County currently has one of the lowest per-capita availability rates in the state.
Independent analysis confirms the region has the capacity to build roughly 52,000 new homes within existing urban growth boundaries.
“Housing for Healthy Communities” Initiative
This is a new policy initiative focused on creating “missing middle” housing by encouraging jurisdictions to opt into two state laws.
SB-10: Allows for the creation of up to 10 housing units on a single parcel in transit-oriented or infill areas.
AB-1033: Allows Accessory Dwelling Units (ADUs) to be sold separately as condominiums, creating new starter-home opportunities without new construction. The goal is to build gentle density and create more diverse housing options, similar to older, walkable neighborhoods, by reversing decades of exclusionary zoning.
Fiscal Benefits of Infill Housing
Denser, infill housing provides a significant financial benefit to cities facing budget deficits. It maximizes property tax revenue per acre. An apartment building can generate $17M-$35M in taxable value per acre, compared to $9M-$11M for single-family homes. It minimizes long-term liabilities for cities. Delivering and maintaining infrastructure like roads, water, and sewer is significantly cheaper on a per household basis in denser areas.
