Accessory Dwelling Unit Ordinance Update

  • On February 14, 2023, the Santa Barbara City Council adopted Ordinance 6103 (Title 30) and 6104 (Title 28) to update the City’s Accessory Dwelling Unit (ADU) ordinances consistent with state law.
  • Since that time additional legislation has been adopted, including but not limited to SB 477, SB 1211 in 2024 and most recently the Governor signed four additional bills related to ADUs on October 13, 2025 (AB 462, AB 1154, SB 543, SB 9).
  • The 2023-2031 Housing Element includes a program to update the ADU ordinances to assist ADU applicants and ensure compliance with state law. Staff will complete the ADU ordinance update process within the next year in accordance with the Housing Element.
  • Where discrepancies exist between the City’s ADU ordinances and newly enacted state law, staff defaults to state law.
