Accessory Dwelling Unit (ADU)

Welcome to the City of Oceanside's Accessory Dwelling Unit (ADU) resource page. The information on this page is intended to help Oceanside residents understand zoning regulations, building codes, and the process for constructing an ADU in the City of Oceanside. 


Tuesday, November 12

6:00 PM to 8:00 PM

City Council Chambers

The City of Oceanside, in partnership with the ADU Coalition of San Diego and AARP California, will conduct a public workshop on Accessory Dwelling Units (ADUs). The workshop will be held on Tuesday, November 12, 2019, in the City Council Chambers at 300 N. Coast Highway, Oceanside from 6:00 PM to 8:00 PM. Doors open at 5:30 PM.

Oceanside residents who are interested in constructing an ADU are encouraged to attend this informative workshop. Topics include:

  • An overview of new ADU legislation
  • City regulations and incentives
  • Guidance through the permitting and construction process
  • An overview of cost and financing

The State legislature enacted ADU legislation in 2017 and 2018 (SB 1069, AB 2299, SB 229, & AB 494)  with the intent to reduce regulatory barriers and costs, streamline approval, and expand the potential capacity for ADUs in response to California's housing shortage. The City Council adopted revised ADU regulations on August 9, 2017 and May 9, 2018, conforming to the provisions of Government Code Section 65852.2 as mandated by state law.

The City's Accessory Dwelling Unit Ordinance is located in Article 30, Section 3006 of the Zoning Ordinance. Key revisions to the ordinance include the waiver of certain development impact fees, flexible parking requirements or parking waivers, and a streamlined permit review process.
