Notwithstanding any other provision of this division and any local law, a local agency shall ministerially approve, as set forth in this section, a parcel map for an urban lot split only if the local agency determines that the parcel map for the urban lot split meets all the following requirements:
The parcel map subdivides an existing parcel to create no more than two new parcels of approximately equal lot area provided that one parcel shall not be smaller than 40 percent of the lot area of the original parcel proposed for subdivision.
Except as provided in subparagraph (B), both newly created parcels are no smaller than 1,200 square feet.
A local agency may by ordinance adopt a smaller minimum lot size subject to ministerial approval under this subdivision.
The parcel being subdivided meets all the following requirements:
The parcel is located within a single-family residential zone.
The parcel subject to the proposed urban lot split is located within a city, the boundaries of which include some portion of either an urbanized area or urban cluster, as designated by the United States Census Bureau, or, for unincorporated areas, a legal parcel wholly within the boundaries of an urbanized area or urban cluster, as designated by the United States Census Bureau.
The parcel satisfies the requirements specified in subparagraphs (B) to (K), inclusive, of paragraph (6) of subdivision (a) of Section 65913.4, as that section read on September 16, 2021.
The proposed urban lot split would not require demolition or alteration of any of the following types of housing:

Housing that is subject to any form of rent or price control through a public entity’s valid exercise of its police power.
A parcel or parcels on which an owner of residential real property has exercised the owner’s rights under Chapter 12.75 (commencing with Section 7060) of Division 7 of Title 1 to withdraw accommodations from rent or lease within 15 years before the date that the development proponent submits an application.
Housing that has been occupied by a tenant in the last three years.
The parcel is not located within a historical landmark property included on the State Historic Resources Inventory, as defined in Section 5020.1 of the Public Resources Code, or within a site that is designated or listed as a city or county landmark pursuant to a city or county ordinance.
The proposed urban lot split does not require demolition or alteration of either of the following:
A contributing structure located within either a historic district that is included on the California Register of Historical Resources or within a historic district listed or designated pursuant to a city or county ordinance.
An existing exterior structural wall of a structure located within either a historic district that is included on the California Register of Historical Resources or within a historic district listed or designated pursuant to a city or county ordinance.
The parcel has not been established through prior exercise of an urban lot split as provided for in this section.
Neither the owner of the parcel being subdivided nor any person acting in concert with the owner has previously subdivided an adjacent parcel using an urban lot split as provided for in this section.
An application for a parcel map for an urban lot split shall be approved in accordance with the following requirements:
A local agency shall approve or deny an application for a parcel map for an urban lot split ministerially without discretionary review.
An application for an urban lot split shall be considered and approved or denied within 60 days from the date the local agency receives a completed application. If the local agency has not approved or denied the completed application within 60 days, the application shall be deemed approved.
If a permitting agency denies an application for an urban lot split pursuant to subparagraph (B), the permitting agency shall, within the time period described in subparagraph (B), 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.
A local agency shall approve an urban lot split only if it conforms to all applicable objective requirements of the Subdivision Map Act (Division 2 (commencing with Section 66410)), except as otherwise expressly provided in this section.
Notwithstanding Section 66411.1, a local agency shall not impose regulations that require dedications of rights-of-way or the construction of offsite improvements for the parcels being created as a condition of issuing a parcel map for an urban lot split pursuant to this section.
Except as provided in paragraph (2), notwithstanding any local law, a local agency may impose objective zoning standards, objective subdivision standards, and objective design review standards that are related to the design or to improvements of a parcel, consistent with paragraph (3) of subdivision (b) and with subdivision (e), and are applicable to a parcel created by an urban lot split that do not conflict with this section.
A local agency shall not impose objective zoning standards, objective subdivision standards, and objective design review standards that would have the effect of physically precluding the construction of two units on either of the resulting parcels or that would result in a unit size of less than 800 square feet.
Notwithstanding paragraph (2), no setback shall be required for an existing structure or a structure constructed in the same location and to the same dimensions as an existing structure.
Notwithstanding paragraph (2), in all other circumstances not described in subparagraph (A), a local agency may require a setback of up to four feet from the side and rear lot lines.
Notwithstanding subdivision (a), a local agency may deny an urban lot split if the building official makes a written finding, based upon a preponderance of the evidence, that the proposed housing development project would have a specific, adverse impact, as defined and determined in paragraph (2) of subdivision (d) of Section 65589.5, upon public health and safety for which there is no feasible method to satisfactorily mitigate or avoid the specific, adverse impact.

This subdivision shall not apply to an applicant that is a “community land trust,” as defined in clause (ii) of subparagraph (C) of paragraph (11) of subdivision (a) of Section 402.1 of the Revenue and Taxation Code, or is a “qualified nonprofit corporation” as described in Section 214.15 of the Revenue and Taxation Code.

Notwithstanding paragraph (3) of subdivision (c), an application shall not be rejected solely because it proposes adjacent or connected structures provided that the structures meet building code safety standards and are sufficient to allow separate conveyance.
For purposes of this section, both of the following shall apply:
“Objective zoning standards,” “objective subdivision standards,” and “objective design review standards” mean standards that involve no personal or subjective judgment by a public official and are uniformly verifiable by reference to an external and uniform benchmark or criterion available and knowable by both the development applicant or proponent and the public official prior to submittal. These standards may be embodied in alternative objective land use specifications adopted by a local agency, and may include, but are not limited to, housing overlay zones, specific plans, inclusionary zoning ordinances, and density bonus ordinances.
“Local agency” means a city, county, or city and county, whether general law or chartered.
A local agency may adopt an ordinance to implement the provisions of this section. An ordinance adopted to implement this section shall not be considered a project under Division 13 (commencing with Section 21000) of the Public Resources Code.
