JADU Owner-Occupancy Rules Loosened.

AB 1154, Carrillo. Junior accessory dwelling units.

What AB 1154 Does.

Narrows the owner-occupancy requirement for Junior ADUs to apply only when the JADU shares sanitation facilities (bathroom) with the single-family dwelling. JADUs with independent bathrooms are now exempt from owner-occupancy requirements, and the bill clarifies that all JADU rentals must be for terms longer than 30 days.

What It Means For You.

JADU owner-occupancy is now required only when the JADU shares a bathroom with the main house. A self-contained JADU no longer chains you to the property.

The Official Summary.

Below is the Legislative Counsel's Digest, the official plain-language summary that accompanies every California bill.

Legislative Counsel's Digest · AB 1154 (2025)

The Planning and Zoning Law, among other things, provides for the creation of

junior accessory dwelling units by local ordinance, or, if a local agency has not adopted an ordinance, by ministerial approval, in accordance with specified standards and conditions. Existing law requires an ordinance that provides for the creation of a junior accessory dwelling unit to, among other things, require owner-occupancy in the single-family residence in which the junior accessory dwelling unit is permitted.

Under this bill, that owner-occupancy requirement would apply only if the junior accessory dwelling unit has shared sanitation facilities with the existing structure. The bill would require an ordinance that provides for the creation of a junior accessory dwelling unit to require that a rental of a junior accessory dwelling unit be for a term longer than 30 days.

Show The Full Digest

By imposing new duties on local governments with respect to the approval of junior accessory dwelling units, the bill would impose a state-mandated local program.

The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement.

This bill would provide that no reimbursement is required by this act for a specified reason.
