Accessory Dwelling Units (ADUs)

In Government Code Section 65852.150, the California Legislature found and declared that allowing accessory dwelling units (ADUs) in zones that allow single-family and multi-family uses provides additional rental housing and is an essential component in addressing California’s housing needs. ADUs are a unique opportunity to address a variety of housing needs and provide affordable housing options for family members, friends, students, the elderly, in-home health care providers, people with disabilities, and others. Further, ADUs offer an opportunity to maximize and integrate housing choices within existing neighborhoods. 

On March 2, 2021 the City Council adopted an ADU Ordinance, providing standards for the development of ADUs on single- and multi-family properties throughout the City. See City Code Section 6.85.050 for City ADU regulations and requirements.

City applications for ADU development are reviewed through a ministerial process that involves submittal of a building permit applications and staff level plan review.  The City permit application checklist, forms and information on digitally submitting your application are available at
