PA-2021-004 / Zoning Text Amendments SMMC 27.19 & 27.04.165 (c) -  ADU/JADU Ordinance Update 

Project Description

Project Update

  • Staff is currently working on a revised draft ordinance that will be introduced to the City Council in the near future (date to be determined). The draft ordinance will be informed in part by feedback collected during community outreach efforts, the requirements of the Department of Housing and Community Development (HCD); peer review of development standards adopted by other jurisdictions in the county; staff recommendations based on experience processing ADU permits; and the recommendations and instruction received from both the Planning Commission and City Council previously.
  • On September 7, 2021, the City Council reviewed the proposed text amendments to San Mateo Municipal Code Chapter 27.19 – “Accessory Dwelling Unit and Junior Accessory Dwelling Unit – Residential Zones” in accordance with changes to State law Government Code § 65852.2 and § 65852.22, and provided comments and guidance to staff on specific areas remaining under local discretion during study-session.
  • On August 24, 2021, the Planning Commission will review the proposed text amendments to San Mateo Municipal Code Chapter 27.19 – “Accessory Dwelling Unit and Junior Accessory Dwelling Unit – Residential Zones” in accordance with changes to State law Government Code § 65852.2 and § 65852.22, and provide a recommendation to the City Council.
  • The City of San Mateo held two virtual Community Workshops on June 24 & 26, 2021, regarding the city’s Accessory Dwelling Unit (ADU) and Junior Accessory Dwelling Unit (JADU) Ordinance Update. The workshop’s provided an overview of the recent changes to state ADU/JADU law, and focused on obtaining community input on how these types of dwellings should look in the community. There were opportunities for attendees to ask clarifying questions and respond to poll questions that will serve to help inform the development of an update to San Mateo’s ADUs/JADU regulations. 
  • On April 5, 2021, the City Council pulled the draft Ordinance from the consent calendar and voted 4-0, disapproving the Ordinance as proposed, and instructed staff to perform community engagement and return with a revised ordinance reflective of input provided by the public. The meeting materials are available on the Public Meeting Portal.
  • The proposed draft ordinance was introduced to the City Council on March 15, 2021. The City Council voted 4-1 to introduce an Ordinance to amend San Mateo Municipal Code Chapter 27.19 – “Accessory Dwelling Unit and Junior Accessory Dwelling Unit – Residential Zones” in accordance with changes to State law and “Junior Accessory Dwelling Unit” definition, as amended to allow detached accessory dwelling units to be built up to a maximum of 16 feet to top-of-plate and up to 24 feet overall to the top ridgeline, as measured from existing grade.  The meeting materials available on the Public Meeting Portal.
  • On February 9, 2021, the Planning Commission voted 4-1 to recommend the proposed draft ordinance to amend San Mateo Municipal Code (SMMC) Chapter 27.19 – “Accessory Dwelling Unit and Junior Accessory Dwelling Unit – Residential Zones” in accordance with recent changes to state ADU and JADU legislation that went into effect January 1, 2020, and to modify SMMC Ch. 27.04.165 (c) “Junior accessory dwelling unit” definition. 
  • On March 2, 2020, Staff updated City Council regarding changes to State Law associated with ADU/JADU development, as well as to discuss the limited areas of regulation which remain under the City’s discretion. The Council provided Staff general direction to study a number of technical areas including a tiered minimum or “by-right” ADU size based on lot size; developing a maximum building height for ADUs and exemptions to address additional parking associated with ADU/JADUs; and exploring ways to expedite and streamline the permitting process. The Council agreed to continue banning short-term rentals on all ADUs, and to allow existing non-code compliant ADUs to remain provided they meet health and safety considerations. The Council was unanimous agreement that additional community outreach should be conducted by the City to ensure the community is informed on the recent changes to State Law.
