  • (4) The applicant shall provide easements for the provision of public services and facilities as required.

  • (5) Units constructed on sites created pursuant to Government Code section 66411.7 shall adhere to the following:

    • a. All new development shall be constructed, in accordance with code standards and design guidelines applicable to the R1 Single-Family Residential District.

  • (6) All lots shall have a minimum street frontage of ten feet to provide for vehicular access, or 16-foot frontage if the driveway serves two units. For a lot without physical street frontage, access to street frontage shall be provided by the granting of a duly recorded permanent easement for ingress and egress purposes in favor of the lot without physical street frontage.

  • (7) In order to preserve the City's inventory of on-street parking, existing and proposed development pursuant to Government Code section 66411.7 shall be limited to one driveway ingress/egress per resultant lot.

• (8) Required off-street parking shall consist of at least one garage parking space per unit and the location and configuration of such parking shall be in compliance with the standards set forth in this code, except that no parking requirements shall be imposed in either of the following circumstances:

  - a. The parcel is located within one-half mile walking distance of either a high-quality transit corridor as defined by Public Resources Code section **21155(b)** or a major transit stop as defined in Public Resources Code section **21064.3** ; or 
  
  - b. There is a car share vehicle located within one block of the parcel. 
  

• (d) The city shall not deny an application based on any of the following:

  • (1) The city shall not require dedications of rights-of-way or the construction of off-site improvements for the parcels being created as a condition of issuing a parcel map.

  • (2) The city shall not impose any objective zoning, subdivision, or design standards that would have the effect of physically precluding the creation of two units on either of the resulting parcels or that would result in a unit size of less than 800 square feet. If the city determines that the strict application of objective zoning, subdivisions or design standards would physically preclude the development of two units on a lot each with a minimum unit size of 800 square feet, the city may ministerially allow deviations from development standards generally applicable to the R-1 zoning district pursuant to city policies and/or regulations implementing this section if such deviation is in compliance with applicable building and fire code standards and regulations and if there are no other feasible means of complying with state law.

  • (3) The city shall not require the correction of nonconforming zoning provisions as a condition for the lot split.

  • (4) The city shall not deny an application solely because it proposes an adjacent or connected structure provided that all building code safety standards are met and they are sufficient to allow a separate conveyance.

• (e) An applicant for an urban lot split shall be required to sign an affidavit in a form approved by the city attorney to be recorded against the property stating the following:

  • (1) That applicant intends to occupy one of the housing units as their principal residence for a minimum of three years from the date of approval. This requirement does not apply when the applicant is a "community land trust" or a "qualified nonprofit corporation" as the same are defined in the Revenue and Taxation Code .

  • (2) That the uses shall be limited to residential uses.

  • (3) That any rental of any unit created by the lot split shall be for a minimum of 31 days.

  • (4) That the maximum number of units to be allowed on the parcels is four, including, but not limited to, units otherwise allowed pursuant to density bonus provisions, accessory dwelling units, junior accessory dwelling units, or units allowed pursuant to section 13-36 .

• (f) The city may deny the 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 Government Code section 65589.5(d)(2) , upon the 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.

• (g) This section shall not apply to:

  • (1) Any parcel which has been established pursuant to a lot split in accordance with this section; or

  • (2) Any parcel where the owner of the parcel being subdivided or any person acting in concert with the owner has previously subdivided an adjacent parcel in accordance with this section. For purposes of this section, it will be assumed that where a lot owner purchased the property from an adjacent owner who subdivided his property pursuant to this division within five years of the lot split, the owner is acting in concert with the then owner of the adjacent lot. However, acting in concert is not limited to this situation.

(h) The provisions of this section supersede any contrary provisions contained elsewhere in this code. (Ord. 2025-07, 10/21/2025)
