Purpose. This Section provides objective subdivision standards for urban lot splits with development of two (2) residential units on single-family residential zone lots pursuant to Government Code Sections 66411.7 and 65852.21. Lot subdivision pursuant to this Section does not require discretionary review or a hearing and is approved ministerially through a parcel map application.
B.
Applicability.
1.
This Section applies to single-family residential zone lots that have not been established through prior exercise of an urban lot split pursuant to this Section and Government Code Section 66411.7. For the purposes of this Section, the following zones are considered single-family residential zones: R-1, RPD-4, RPD-56, RPD-126, RPD-153, RPD-169, RPD-284, and RPD-481.
2.
This Section does not permit an urban lot split if an owner of a lot or any person acting in concert with the owner of such lot has previously subdivided an adjacent lot pursuant to this Section and Government Code Section 66411.7.
C.
Subdivision Standards. An urban lot split pursuant to this Section is subject to the following standards.
1.
Eligibility requirements of Government Code Section 66411.7(a) shall be satisfied.
2.
Each lot created by the parcel map shall have a minimum area of one thousand two hundred (1,200) square feet.
3.
The newly created lots shall not be smaller than forty (40) percent of the area of the original lot.
4.
Each lot created by the parcel map shall have frontage on a public street unless the original lot has frontage on a private street.
5.
The original lot shall not be subdivided in a manner such that the boundary between the newly created lots passes through an existing structure that is not being demolished for the project.
6.
More than twenty-five (25) percent of the exterior structural walls of an existing dwelling shall not be demolished if the dwelling has been occupied by a tenant in the three (3) years prior to the urban lot split application.
D.
Exceptions. The Planning Director shall approve an exception to any of the standards specified in this Section upon determining that complying with the standard would physically preclude the construction of up to two (2) residential units or would physically preclude either of the two (2) residential units from being eight hundred (800) square feet in floor area.
E.
Denial. The Planning Director may deny an urban lot split upon making both of the following findings in writing based upon a preponderance of evidence.
1.
The proposed housing development project would have a specific, adverse impact upon the public health and safety or the physical environment as defined and determined in Government Code Section 65589.5(d) (2).
2.
There is no feasible method to satisfactorily mitigate or avoid the specific, adverse impact.
F.
Owner Occupancy Affidavit. Except as provided in Government Code Section 66411.7 for community land trusts and qualified nonprofit corporations, the Planning Director's approval of an urban lot split shall not be effective until the property owner submits an executed affidavit stating that the property owner intends to occupy one of the residential units as a principal residence for a minimum of three (3) years from the date of the approval of the urban lot split.
G.
Short-term Rental Restrictive Covenant. The Planning Director's approval of an urban lot split shall not be effective until the property owner submits an executed restrictive covenant prohibiting short term rental of a residential unit created pursuant to this Section. The restrictive covenant shall prohibit rental for a period less than thirty-one (31) days, shall be in a form approved by the City Attorney, and shall be recorded with the Los Angeles County Registrar-Recorder.
H.
Finality of Decisions. Decisions of the Planning Director administering this Section shall be final and shall not be subject to appeal.
