Bakersfield, CA Accessory Structures: ADU Permits (2026)

BMC Chapter 17.65 implements the ministerial-approval regime required by Cal. Gov. Code §65852.2. An applicant submits a site plan review application to the Planning Division showing the proposed ADU footprint, setbacks, parking, and architectural compatibility, then files for a building permit with the Building Division. Detached new-construction ADUs must respect a 4-foot maximum required side and rear setback (the city may not require more). ADUs and JADUs must be architecturally compatible with the primary dwelling — same exterior materials and architecture per BMC Ch. 17.65. State law (Cal. Gov. Code §65852.2(b)(1)) requires the city to act on a complete ADU application within 60 days; if denied, the city must supply a full list of objective defects. SB 9 (Cal. Gov. Code §66411.7 and §65852.21) allows ministerial two-unit development and urban lot splits on single-family lots, separate from the ADU pathway. AB 1033 (Cal. Gov. Code §65852.26) authorizes — but does not require — Bakersfield to adopt an ordinance permitting separate condominium conveyance of an ADU; Bakersfield has not yet opted in.
