AB 1154: Junior accessory dwelling units.
What AB 1154 does, verified December 6, 2025
The bill aims to amend the government code to allow for the creation of junior accessory dwelling units. Currently, an ordinance must require owner-occupancy in the single-family residence where the unit is permitted. The proposed change would exempt this requirement if the unit shares sanitation facilities with the main structure. Additionally, the bill would require a rental of the unit to be for a term longer than 30 days. Local governments would need to adopt an ordinance allowing these units and obtain ministerial approval if no local ordinance exists.

Assembly Bill No. 1154

[ Approved by Governor October 10, 2025. Filed with Secretary of State October 10, 2025. ]
LEGISLATIVE COUNSEL'S DIGEST
AB 1154, Carrillo. Junior accessory dwelling units.
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.
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.
The people of the State of California do enact as follows:
SECTION 1.
Section 66333 of the Government Code is amended to read:66333.
Notwithstanding Article 2 (commencing with Section 66314), a local agency may, by ordinance, provide for the creation of junior accessory dwelling units in single-family residential zones. The ordinance may require a permit to be obtained for the creation of a junior accessory dwelling unit, and shall do all of the following:(a) Limit the number of junior accessory dwelling units to one per residential lot zoned for single-family residences with a single-family residence built, or proposed to be built, on the lot.
(b) If the junior accessory dwelling unit has shared sanitation facilities with the existing structure, require owner-occupancy in the single family residence in which the junior accessory dwelling unit will be permitted. The owner may reside in either the remaining portion of the structure or the newly created junior accessory dwelling unit. Owner-occupancy shall not be required if the junior accessory dwelling unit has separate sanitation facilities, or if the owner is another governmental agency, land trust, or housing organization.
(c) Require the recordation of a deed restriction, which shall run with the land, shall be filed with the permitting agency, and shall include both of the following:
(1) A prohibition on the sale of the junior accessory dwelling unit separate from the sale of the single-family residence, including a statement that the deed restriction may be enforced against future purchasers.
(2) A restriction on the size and attributes of the junior accessory dwelling unit that conforms with this article.
(d) Require a permitted junior accessory dwelling unit to be constructed within the walls of the proposed or existing single-family residence. For purposes of this subdivision, enclosed uses within the residence, such as attached garages, are considered a part of the proposed or existing single-family residence.
(e) (1) Require a permitted junior accessory dwelling unit to include a separate entrance from the main entrance to the proposed or existing single-family residence.
(2) If a permitted junior accessory dwelling unit does not include a separate bathroom, the permitted junior accessory dwelling unit shall include a separate entrance from the main entrance to the structure, with an interior entry to the main living area.
(f) Require the permitted junior accessory dwelling unit to include an efficiency kitchen, which shall include all of the following:
(1) A cooking facility with appliances.
(2) A food preparation counter and storage cabinets that are of reasonable size in relation to the size of the junior accessory dwelling unit.
(g) Require that a rental of a junior accessory dwelling unit be for a term longer than 30 days.
SEC. 2.
No reimbursement is required by this act pursuant to Section 6 of Article XIII B of the California Constitution because a local agency or school district has the authority to levy service charges, fees, or assessments sufficient to pay for the program or level of service mandated by this act, within the meaning of Section 17556 of the Government Code.Text of AB 1154 as chaptered, from the official record.
