Mountain View’s Demographics

Housing Types in Mountain View

It is important to have a variety of housing types to meet the needs of a community today and in the future. In 2022, 27.76% of homes in Mountain View were single family detached, 13.18% were single family attached, 7.97% were small multifamily (2-4 units), 48.45% were medium or large multifamily (5+ units) and 2.62% were mobilehomes. Between 2010 and 2020, the number of multi-family units increased more than single-family units. In Mountain View, the share of the housing stock that is detached single family homes is lower than the average of other jurisdictions in the region.

Jobs & Housing in Mountain View

Jobs: 89,738
Employed Residents per Household:  1.35
Jobs per Employed Resident: 1.95
Jobs-Housing Balance Ratio: 2.29
Source: ACS 2022 5 year estimates

Note: Jobs-Housing Balance is a measurement used by planners that assumes that a balanced community is one where people can both live and work. This ratio compares the number of jobs in a community to the number of housing units.

Jobs-Housing Fit: 5.29 low wage jobs per 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 Mountain View, there are more than 4 low-wage workers competing for each affordable home.

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 Mountain View

Total Rental Homes: 20,919
Overcrowded Rental Homes: 1,297
Severely Overcrowded Rental Homes: 1,532
Percent of Rental Homes, Overcrowded: 13.52%
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. 

2014-2022 Regional Housing Needs Allocation 

Every eight years, the Regional Housing Needs Allocation (RHNA) process is used to assign each city and county in California their “fair share” of new housing units to build. These units of housing are intended to accommodate existing need and projected growth in the region. The RHNA process is critical because it requires all cities and counties to plan for the housing needs of their residents, regardless of income, in an effort to plan for future growth and ease the Bay Area’s acute housing crisis. 

Many cities and counties regularly fall short of their RHNA targets, as the Bay Area’s housing crisis continues to grow. Each spring, jurisdictions are required to provide an Annual Progress Report to show how effective their efforts have been in achieving housing development targets by income level. The table below shows Mountain View’s progress.

2023-2031 RHNA Allocation

In January of 2023, about a year after local jurisdictions are given their final RHNA numbers, the local planning process will culminate in the Housing Element. This is a pivotal document that serves as a Constitution for land use planning and accounts for how and where the jurisdiction will accommodate allocated housing units. It must identify adequate sites for the full RHNA and all types of housing, including emergency shelters, rental housing, and ownership housing, and commit to policies and programs aimed at removing barriers to housing production, addressing racial and economic segregation and disparities in access to resources, providing for the unique housing needs of residents in protected categories, and protecting residents vulnerable to displacement.

Jobs & Housing in the Development Pipeline

As of January 2022, Mountain View has 2.7 jobs in the development pipeline for every 1 housing unit in the development pipeline.

Pipeline as of January 2022. Information reported from City of Mountain View.  The employment projections are derived by applying square-footage-per-employee factors to building floor areas by four building types: 250 square feet for office/R&D; 1,500 feet for hotels; 550 feet for retail/restaurant; and 2,500 feet for manufacturing/warehouse. All are figures applied to a building’s gross square footage.

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

The Housing Element of Mountain View’s General Plan includes a series of policies to encourage affordable housing development, including:

• City initiation of partnerships and continuing to work with developers for the development of affordable housing, especially housing affordable to extremely low-income households.
• Assessment of the feasibility of utilizing City-owned properties as subsidized housing development sites when appropriate and feasible.
• Proactive encouragement of redeveloping underutilized sites and facilitation of parcel assembly to create development sites.

Additionally, the City is:

• Reassessing residential development standards to ensure that there is flexibility under zoning regulations to permit such innovative housing types as co-housing, shared housing, and intergenerational housing.
• Initiating discussions with housing developers to review land and financial resources, development incentives, and the City’s entitlement process to promote alternative and innovative forms of residential development.

Inclusionary Housing

The City of Mountain View has an inclusionary housing policy that requires all residential developments with 7 or more units to designate 15 percent of the total units for moderate income households between 80% and 120% AMI at a weighted average of 100%. Alternatively, rowhouse and townhouse developments may provide 20% inclusionary units for households between 80% and 150% AMI, with a weighted average of 120%. Rather than providing inclusionary units as part of the development, for-sale residential projects with 3 to 7 units may pay an in-lieu fee for each unit that is equivalent to 3 percent of the sales price.  

For-rent residential developments with 7 or more units are required to designate 15 percent of the total units for low income households below 80% of the area median income. Alternately, applicants may petition the Mountain View City Council to pay an in-lieu fee or other alternative compliance method in place of providing affordable housing on-site.

All BMR units are required to be reasonably dispersed throughout the project and consistent with federal and state fair housing laws, have a distribution of units by number of bedrooms proportionate to the market-rate units, and be of comparable size based on net habitable square footage of the units, except that affordable units for seniors shall comply with applicable requirements for senior housing.

Affordable Housing Impact Fees

The City of Mountain View has an affordable housing impact fee policy that requires rental housing developments with 5 or more units to pay a $17 per square foot impact fee, which is used to fund the creation of affordable housing for low-income households (50-80% AMI).  

The City also charges impact fees for non-residential development at the following levels:

• Office, High Tech, Industrial: $29.62 per square foot.
• Hotel, Retail, Entertainment: $3.17 per square foot.

**Office, High Tech, and Industrial under 10,000 sq. ft. pays half the fee, and Commercial, Hotel, and Retail under 25,000 sq. ft. pays half the fee.
