(a) Notwithstanding Section 65852.2, 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:
(1) 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.
(2) 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 owner is another governmental agency, land trust, or housing organization.
(3) 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:
(A) 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.
(B) A restriction on the size and attributes of the junior accessory dwelling unit that conforms with this section.
(4) 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 paragraph, enclosed uses within the residence, such as attached garages, are considered a part of the proposed or existing single-family residence.
(5)
(A) Require a permitted junior accessory dwelling unit to include a separate entrance from the main entrance to the proposed or existing single-family residence.
(B) 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.
(6) Require the permitted junior accessory dwelling unit to include an efficiency kitchen, which shall include all of the following:
(A) A cooking facility with appliances.
(B) A food preparation counter and storage cabinets that are of reasonable size in relation to the size of the junior accessory dwelling unit.
(b)
(1) An ordinance shall not require additional parking as a condition to grant a permit.
(2) This subdivision shall not be interpreted to prohibit the requirement of an inspection, including the imposition of a fee for that inspection, to determine if the junior accessory dwelling unit complies with applicable building standards.
(c)
(1) An application for a permit pursuant to this section shall, notwithstanding Section 65901 or 65906 or any local ordinance regulating the issuance of variances or special use permits, be considered ministerially, without discretionary review or a hearing. The permitting agency shall either approve or deny the application to create or serve a junior accessory dwelling unit within 60 days from the date the local agency receives a completed application if there is an existing single-family dwelling on the lot. If the permit application to create or serve a junior accessory dwelling unit is submitted with a permit application to create or serve a new single-family dwelling on the lot, the permitting agency may delay approving or denying the permit application for the junior accessory dwelling unit until the permitting agency approves or denies the permit application to create or serve the new single-family dwelling, but the application to create or serve the junior accessory dwelling unit shall still be considered ministerially without discretionary review or a hearing. If the applicant requests a delay, the 60-day time period shall be tolled for the period of the delay. A local agency may charge a fee to reimburse the local agency for costs incurred in connection with the issuance of a permit pursuant to this section.
(2) If a permitting agency denies an application for a junior accessory dwelling unit pursuant to paragraph (1), the permitting agency shall, within the time period described in paragraph (1), return in writing a full set of comments to the applicant with a list of items that are defective or deficient and a description of how the application can be remedied by the applicant.
(d) A local agency shall not deny an application for a permit to create a junior accessory dwelling unit pursuant to this section due to the correction of nonconforming zoning conditions, building code violations, or unpermitted structures that do not present a threat to public health and safety and that are not affected by the construction of the junior accessory dwelling unit.
(e) For purposes of any fire or life protection ordinance or regulation, a junior accessory dwelling unit shall not be considered a separate or new dwelling unit. This section shall not be construed to prohibit a city, county, city and county, or other local public entity from adopting an ordinance or regulation relating to fire and life protection requirements within a single-family residence that contains a junior accessory dwelling unit so long as the ordinance or regulation applies uniformly to all single-family residences within the zone regardless of whether the single-family residence includes a junior accessory dwelling unit or not.
(f) For purposes of providing service for water, sewer, or power, including a connection fee, a junior accessory dwelling unit shall not be considered a separate or new dwelling unit.
(g) This section shall not be construed to prohibit a local agency from adopting an ordinance or regulation related to a service or a connection fee for water, sewer, or power, that applies to a single-family residence that contains a junior accessory dwelling unit, so long as that ordinance or regulation applies uniformly to all single-family residences regardless of whether the single-family residence includes a junior accessory dwelling unit.
(h) If a local agency has not adopted a local ordinance pursuant to this section, the local agency shall ministerially approve a permit to construct a junior accessory dwelling unit that satisfies the requirements set forth in subparagraph (A) of paragraph (1) of subdivision (e) of Section 65852.2 and the requirements of this section.
(i) For purposes of this section, the following terms have the following meanings:
(1) “Junior accessory dwelling unit” means a unit that is no more than 500 square feet in size and contained entirely within a single-family residence. A junior accessory dwelling unit may include separate sanitation facilities, or may share sanitation facilities with the existing structure.
