More and more, purchasing a home is out of reach for many while renters face rent prices that are just too high. Just about every city in the region needs more housing, of all types and sizes. Portola Valley’s needs, as laid out in the Housing Strategic Plan, identify the following populations for housing support:
- Seniors with limited options to age in the community
- Young adults who grew up in Portola Valley who do not have options to stay
- Workforce that commutes long distances and pays high rents to support the community
Housing Elements are housing plans that are one part of the General Plan – a guide to all the ways each city, town or county is planned and managed, from our roads to our parks and neighborhoods. With an update required every eight years by the State of California, this Housing Element update will create a foundation for all the policies and programs related to housing. Learn more here.
The Ad Hoc Housing Element Committee began meeting in June/July 2021, and serve through December 2022. Committee members are anticipated to:
- Provide recommendations to the Town Council on an updated Housing Element that provides means to accommodate additional housing units
- Explore options to minimize the impacts of additional housing units on the Town’s character, safety concerns, and traffic.
- Maximize public participation in the update by encouraging residents, business owners, and the Town’s diverse workforce to attend meetings and share ideas
- Communicate information on the Committee’s progress and recommendations to residents

Community Conversations on Housing |
Home for All |
The Town utilized a grant from San Mateo County’s Home for All initiative to conduct two “Community Conversations on Housing,” or convenings, in 2018. The first convening was held on March 3rdand focused on participants sharing their ideas, thoughts, and stories about housing in Portola Valley. As a result of interest expressed at the first meeting, the Town held a second Community Conservation on May 5th that focused on second units, Town’s policies on second units, and converting a bedroom to an independent unit. |
Town of Portola Valley was awarded a grant in 2017 from Home for All to pilot new approaches to community engagement around the topic of housing. Home for All is a community collaborative addressing housing challenges in San Mateo County through convening community, sharing information and promoting innovation. |
Council Study Session on Second Units (ADUs) |
Rich Gordon's Housing Element Task Force |
Council Study Session on ADUs (Second Units) On July 11, 2018, the Town Council held a study session on ADUs. This study session was in response to suggestions from residentswho participated in the May 5, 2018 ADU Convening and helped the Council to develop a priority list for the Planning Commission’s work on ADUs in the next few months. It is anticipated that the Council will review the Commission’s work for potential adoption in early 2019. To kick off the discussion, staff shared information about the Town’s current ADU regulations and shared a list of ideas that could be considered to encourage their construction. None of the staff-generated ideas were recommendations; instead, they were offered to provide the maximum number of ideas thatcouldbe considered. The Council also heard from residents who attended the meeting, who overwhelmingly supported efforts to expand second unit opportunities. |
Assemblyman Gordon has assembled a task force to identify legislative options to address the pressing needs to balance local control and state mandates, while also addressing the need for affordable housing in the region. Councilmember Derwin and staff will continue to be active participants in this effort. |
Housing Strategic Plan |
State Housing Element Requirements |
In 2016, the Town Council identified housing in Portola Valley as a priority and formed theAd-Hoc Housing on Town Owned Property Committeeas part of theHousing Strategic Plan.The Committee's mission is to examine the possibility of whether any Town-owned properties may be appropriate for modest housing opportunities to support the communities, teachers, public safety workers, and employees. The Committee will not recommend any projects to the Council; rather, they would formally suggest that the Council further review recommended properties for potential housing at a future Council meeting. |
The Town's overall plan for housing is set forth in the Housing Element of the General Plan, which describes the Town's goals for housing and programs to plan for and encourage housing in the Town. |
