Jobs-Housing Fit: 149 low wage jobs with 0 low-cost rental unit
Source: Jobs from LEHD Origin-Destination Employment Statistics 2021; households from U.S. Census, American Community Survey B25056, B25061

Note: Jobs-Housing Fit measures the mismatch between wages and housing affordability as the ratio of low-wage jobs (less than $3,333/month) to the number of low-cost rental units (less than $1,500/month). In Monte Sereno, there are almost 5 low-wage workers competing for each affordable home.

Cost-Burdened (30% – 50% income spent on housing)
Renter Households: 11% of renter households (7)
Homeowner Households: 31.4% of homeowner households (380)

Severely Cost-Burdened (more than 50% of income spent on housing)
Renter Households: 0 of renter households
Homeowner Households: 17.52% of homeowner households (380)
Source: ACS 2022 5 year estimates

Note: Current standards measure housing cost in relation to gross household income: households spending more than 30 percent of their income, including utilities, are generally considered to be overpaying or “cost burdened.” Severe cost burden occurs when households pay 50 percent or more of their gross income for housing. The impact of high housing costs falls disproportionately on extremely low-, very low-, and low-income households, especially renters. While some higher-income households may choose to spend greater portions of their income for housing, the cost burden for lower-income households reflects choices limited by a lack of a sufficient supply of housing affordable to these households.

Overcrowding in Monte Sereno

Total Rental Homes: 62
Overcrowded Rental Homes: 0
Severely Overcrowded Rental Homes: 0
Percent of Rental Homes, Overcrowded: 0%
Source: ACS 2022 5 year estimates

  • The U.S. Census defines an overcrowded unit as one occupied by 1.01 persons or more per room (excluding bathrooms and kitchens). Units with more than 1.5 persons per room are considered severely overcrowded.

Note: Overcrowding increases health and safety concerns and stresses the condition of the housing stock and infrastructure. Overcrowding is strongly related to household size (particularly for large and very-large households) and the availability of suitably sized housing. Overcrowding impacts both owners and renters; however, renters are generally more significantly impacted. 

2022-2031 Regional Housing Needs Allocation (RHNA) 

Every eight years, the Regional Housing Needs Allocation (RHNA) process is used to assign each city and county in California their “fair share” of the region’s housing need, by income level. These homes are intended to address the housing shortage, meeting the needs of existing residents and accommodating projected growth in the region. 

The RHNA process is critical because state law requires each city and county to make a specific, actionable, and measurable plan, called a Housing Element, that complies with state law and addresses housing needs. It must identify enough sites to hold the RHNA, by income level, and create programs that remove barriers to housing production and protect residents vulnerable to displacement. Local jurisdictions must also take significant steps to affirmatively further fair housing (AFFH), addressing racial and economic segregation and disparities in access to resources, and meeting the unique housing needs of residents in protected groups. The California Department of Housing and Community Development (HCD) is responsible for certifying Housing Element compliance with state law.

In the past, many cities and counties have fallen far short of their RHNA targets, as the Bay Area’s housing crisis continues to grow. In this planning cycle, new laws give HCD additional tools to provide technical assistance and hold jurisdictions accountable to their plans. Each spring, jurisdictions are required to complete an Annual Progress Report on the Housing Element, including the number of homes permitted by income level, program actions taken, and outcomes achieved. The table below shows Monte Sereno’s target in the sixth cycle and progress to date in permitting new homes.

SOURCE: Units reported in the Housing Element Annual Performance Report that received building permits through 2023 were added to the unit counts in the previously reported 2018 Base Year table.  This methodology necessarily means that any ELI units, if any, are included in the VLI category since that is how HCD has required production data to be reported.  The RHNA data on new units relies on self-reporting by jurisdiction and can include units for which building permits were issued that never got built.  The percentage of the total housing stock in the community is based the California Department of Finance’s Table E-5.

Accessory Dwelling Units (ADUs)

All California cities and counties are mandated to permit ADUs and JADUs according to state law. The Legislature further updated ADU and JADU law effective January 1, 2021 to clarify and improve various provisions in order to promote the development of ADUs and junior accessory dwelling units (JADUs). These include allowing ADUs and JADUs to be built concurrently with a single-family dwelling, opening areas where ADUs can be created to include all zoning districts that allow single-family and multifamily uses, modifying fees from utilities such as special districts and water corporations, limited exemptions or reductions in impact fees, and reduced parking requirements. Please see the Accessory Dwelling Unit Handbook (PDF) for more information for local government bodies and homeowners interested in adding an ADU or JADU to their property. Our partner, the Housing Trust of Silicon Valley has kicked-off a major initiative, Small Homes, Big Impact to support ADU development throughout Santa Clara County, including outreach and education, and potential new financing mechanisms.

Affordable Housing Policies

Housing Element Policies

Monte Sereno relies primarily on the development of secondary units on single-family properties to meet its affordable housing objectives.  To this end, it has amended its second-units program to allow larger units, uncovered parking, fee waivers for rent-restricted units, and an amnesty program.  The City has established a multi-family zoning district which has yet to be utilized.  And the City allows residential care homes, supportive housing and transitional housing by right in all residential zoning districts.

The Housing Element of Monte Sereno’s General Plan includes policies pledge to:

  • Work with nearby communities to explore countywide housing needs and solutions, and requires the City Manager to report annually on such activities.
  • Monitor the availability of federal and State affordable housing funding and apply for such funds if available.
