18.20.170 Ministerial Approval of Urban Lot Splits.

A. The Director of Community Development shall ministerially approve a parcel map application for an urban lot split if it meets the requirements of Government Code Section 66411.7 and conforms to all applicable objective requirements of the Subdivision Map Act (commencing with Government Code Section 66410). No public hearing shall be required. Notice shall be provided to adjacent property owners (including those across any public or private street) fourteen days prior to any action on the proposed project. The decision of the Director of Community Development shall be final.

B. The Director of Community Development shall require an urban lot split pursuant to this section to comply with objective zoning standards, objective subdivision standards, and objective design review standards applicable to the parcels created pursuant to this Section, to the extent that such standards do not conflict with Government Code Section 66411.7, including but not limited to the objective subdivision standards in Paragraph G.

C. Notwithstanding Paragraph A, the Director of Community Development may deny an urban lot split proposed pursuant to this Section, if the Building Official makes a written finding, based upon a preponderance of the evidence, that any housing development project proposed in connection with the lot split would have a specific, adverse impact, as defined and determined in Government Code Section 65589.5(d)(2), upon public health and safety or the physical environment and for which there is no feasible method to satisfactorily mitigate or avoid the specific, adverse impact.

D. In addition to any other conditions established in accordance with this Section, the Director of Community Development may require any of the following conditions when considering an application for a parcel map for an urban lot split pursuant to this Section:

  1. Easements required for the provision of public services and facilities.

  2. A requirement that the parcels have access to, provide access to, or adjoin the public right-of-way.

E. Any lot created pursuant to this Section shall be limited to residential uses.

F. An applicant for an urban lot split shall provide proof, to the satisfaction of the Director of Community Development, that the property has not been occupied by a tenant in the three years preceding the submission of an application.

G. An applicant for an urban lot split pursuant to this Section shall sign an affidavit stating that the applicant intends to occupy a housing unit on one of the lots created as their principal residence for a minimum of three years from the date of the approval of the urban lot split; provided, however, that this Paragraph shall not apply to an applicant that is a community land trust, as defined in Revenue and Taxation Code Section 402.1(a)(11)(C)(ii), or is a qualified nonprofit corporation, as described in Revenue and Taxation Code Section 214.15.

H. Objective Subdivision Standards for Ministerially Approved Lot Splits. In addition to any applicable objective subdivision standards in this Title or the Subdivision Map Act and the requirements of Government Code Section 66411.7, a lot split approved pursuant to this Section must, to the maximum extent permissible under Government Code Section 66411.7, comply with the objective standards including but not limited to objective standards for urban lot splits set forth in Sections 18.20.180, 19.28.060, and 19.40.050.

I. This Section shall remain in effect until such time as Government Code Section 66411.7 is repealed or superseded or its requirements for ministerial approval of lot splits are materially amended, whether by legislation or initiative, or are held to be unenforceable by a court of competent jurisdiction, at which time this Section shall become null and void.

18.20.180 Subdivision Standards for Two-Lot Subdivisions in Single-Family Residential Zones.

A. Lot Configuration

1. Single-Family Residential Zones (R1) a. No more than two new, non-curved property lines may be added to create a new lot. b. Existing interior lots or pie shaped lots with either (i) 60 feet or more street frontage, or (ii) more than 75 feet of street frontage and a lot depth of up to 145 feet, shall result in a street frontage that is between 40-60% of the existing street frontage of the lot being subdivided. Resulting lots shall have a side-by-side orientation and shall not create a landlocked parcel. c. Existing interior lots or pie shaped lots with more than 75 feet of street frontage and a lot depth of more than 145 feet, may be subdivided in one of the following ways: i. Resulting lots shall have a street frontage that is at least 40% of the existing street frontage of the lot being subdivided. Lots shall have a side-by-side orientation and shall not create a landlocked parcel; or ii. One of the resulting lots shall be a flag lot with access to the street. The buildable area of the flag lot shall span the entire distance between the two side property lines that intersect with the front property line of the lot being subdivided. d. Existing interior lots or pie shaped lots with less than 60 feet of street frontage shall result in one flag lot with access to the street. The buildable area of the flag lot shall span the entire distance between the two side property lines that intersect with the front property line of the lot being subdivided. e. Existing flag lot subdivision shall result in lots in the same orientation as the existing lot (i.e., the existing front lot line must be the front lot line of the future lots and the existing rear lot line shall be the rear lot line of the future lots) and that are between 40-60% of the lot width of the lot being subdivided. f. Corner lots shall be subdivided in a manner that splits the existing street side property line to create at least one front lot line on that frontage.
2. Residential Hillside Zones (RHS) a. Up to two new property lines may be added to create a new lot and shall follow the contours of the property. b. Each resulting lot shall share one common driveway. If an existing driveway or curb cut exists, a new driveway or curb cut location shall not be approved. c. If in an area where direct sanitary sewer connection is unavailable, a percolation test completed within the last five years, or if the percolation test has been recertified, within the last 10 years, must be provided. d. Building pads shall be identified on the flattest portion of a lot, closest to an existing driveway. Where no driveway exists, building pads shall be identified on the flattest portion of the lot, closest to the access road unless doing so would result in a combined grading total greater than that required for siting elsewhere on the lot. e. No new or expanded structures shall encroach upon any existing public or private utility easements. f. A cumulative total of 1,250 cubic yards, cut plus fill (including grading for building pad, yard areas, driveway, all other areas requiring grading, and basements), except if the original lot that was subdivided has already performed prior grading, then the amount of grading that has previously occurred shall be reduced from the maximum grading quantity allowed cumulatively on the two resulting lots.
