ADU, Old La Honda Rd, Woodside

In the Spring of 2020, the Town of Woodside updated its Municipal Code to comply with new State regulations governing Accessory Dwelling Units (ADUs) and Junior ADUs.  Woodside is encouraging ADUs in order to meet its affordable housing needs. ADUs can be used to house aging parents, adult children, health care aides, domestic helpers etc., and can be rented out, but not for less than 30 days.

What is an ADU? An ADU is an attached or detached residential dwelling unit (often referred to as a “granny flat” or guest house) that provides complete independent living facilities for one or more persons.  It includes a kitchen and permanent living, sleeping and sanitation provisions on the same parcel as the single-family dwelling.

What is a Junior ADU? A Junior ADU is no more than 500 sq ft and is entirely contained within a main dwelling.  It includes an efficiency kitchen, has a separate exterior entry but can maintain an interior connection to the main dwelling living spaces.

Building an ADU on your Woodside Property.  ADUs can be up to 1500sf in size, but all ADUs in Woodside must have a permanent foundation and permanent utilities. They can be attached to the main dwelling or detached; they can be above a garage, within a barn, or in a basement; they can also be created by converting an existing garage.  One parking space is required for ADUs with one or more bedrooms, and no parking is required for studio ADUs.  They are approved by the Planning Department, and provided they comply with the municipal code, are not required to go through ASRB or Planning Commission. They do need to receive approval from San Mateo County Health Department for septic or sewer capacity.
