Yuba City, CA Accessory Structures: ADU Owner Occupancy (2026)

Under Sec. 5004(e) of the Municipal Code, junior accessory dwelling units carved out of a single-family home come with conditions that do not apply to a full-size, detached accessory dwelling unit. Before the City issues a permit, the owner must record a deed restriction confirming the JADU will never be sold separately from the primary dwelling, and that restriction is enforceable against anyone who later buys the property. Layered on top of that is the owner-occupancy requirement itself: the person who owns the parcel has to actually reside there, whether that means staying in the original house or moving into the converted JADU space.

The only carve-out is for an owner that is a governmental agency, land trust, or housing organization, entities that by definition cannot personally occupy anything. This differs sharply from a standard, detached accessory dwelling unit approved under the same section's state-exemption pathway, which state law bars the City from conditioning on owner occupancy. 5004(B): a 4-foot interior side and rear yard setback, height capped at the height of the existing or proposed primary dwelling, a required efficiency kitchen, matching architectural detailing to the primary home, and no parking requirement. The Development Services Department reviews and approves JADU applications ministerially, without a public hearing, within 60 days of a complete application.
