An accessory dwelling unit (ADU) is an attached or detached structure that provides independent living facilities for one or more persons and includes permanent provisions for living, sleeping, eating, cooking, and sanitation on the same parcel as a single-family dwelling unit. ADUs are sometimes referred to as secondary units, granny units, or in-law units. They can have a separate mailing address and be rented to a third-party or occupied by a property owner(s). 



A Planning Application must be submitted for review by a Planner prior to submitting for a building permit (or plan check review) to ensure compliance with the zoning regulations and preparation of a covenant to be recorded by the County Clerk Recorder. 

ADU Planning Application

ADU Urgency Ordinance (Adopted by City Council on 1-8-2020)

ADU Permitting Process

Planning Permit Fee is $2,197.80


In 2017 and 2018, the State of California adopted a series of regulations for ADUs in all residential zoning districts in an effort to address growing housing demand and reducing affordability across California. These laws went into effect in all cities on January 1st each year:

 2017  2018  2019 
 Senate Bill (SB) 1069   Senate Bill (SB) 229 Senate Bill (SB) 68
 Assembly Bill (AB) 2299  Assembly Bill (AB) 494 Senate Bill (SB) 881
     Senate (SB) 13


The California Department of Housing and Community Development (HCD) has prepared an Accessory Dwelling Unit Memorandum Guide and contains more information on their website. In tandem, the City has prepared map to identify all properties within a 0.5 mile of a public transportation stop and station that qualify for an ADU under State law

On January 7, 2020, the City adopted the attached ADU urgency ordinance, which replaces the Interim Development Control Ordinance adopted by the Council on December 17, 2019.  On January 14, 2020 the City Council will consider the second reading for the Zoning Text Amendment for ADUs.  The development standards in the urgency ordinance and in the Zone Text Amendment (ZTA) ordinance are the same.   If the Council adopts the ZTA ordinance, it will go into effect on February 14, 2020.  Use the development standards in the Urgency Ordinance until the Zoning Text Amendment goes into effect.    


The City prepared revisions to the ADU Interim Ordinance to incorporate:

  • State laws that went into effect January 1, 2018,
  • Lessons learned from City staff review of 100+ ADU permits since April 2017, 
  • Public input from upcoming community meetings, and
  • Further research conducted on ADU implementation in other cities.
  • In October 2019, the State of California adopted SB 13, AB 881, and AB 68, amending State ADU law. As a response, City Council adopted a Interim Development Control Ordinance on December 17, 2019 to comply with State law.
  • The City Council approved an Urgency Ordinance and introduced a Zone Text Amendment on January 7, 2020. The next meeting for the Zone Text Amendment will be January 14, 2020.
