§ 17.905.020. Development and Subdivision Standards.

  • A. Objective development standards. An urban lot split, and any development of a parcel created from an urban lot split, shall comply with all requirements of this chapter, all objective development standards set forth in this Code or otherwise established by the City, and all other City requirements that are not in conflict with Government Code Section 66411.7 .

  • A. Development and subdivision standards. The lot to be split does not satisfy the requirements of Section 17.905.020 (Development and Subdivision), Section 17.905.020 (Development and Subdivision Standards), or Section 17.905.040 (Standards Specific to Urban Lot Splits).

  • B. Zone. The lot to be split is not zoned for single-family residential uses. If the lot is designated as a specific plan area, then it will be considered to be zoned for residential uses under this section if the lot is within a portion of the specific plan where a single-family residence is a permitted use.

  • C. Statutory exemptions. The lot to be split does not satisfy the requirements of Government Code Section 65913.4(a)(6)(B) through (K) . [See Government Code Section 66411.7(a)(3)(C).]

  • D. Inspection.

    1. Very high fire hazard severity zone. For lots within a very high fire hazard severity zone, the application does not include proof of an inspection by the City's building official or other City designee confirming full compliance all existing fire and building code standards.

    2. Earthquake fault zone. For lots within a delineated earthquake fault zone, the application does not include proof of an inspection by the City's building official or other City designee confirming full compliance with applicable seismic protection building code standards. Such inspection shall include all standard City requirements for development within an earthquake fault zone.

  • E. Historic properties and districts. The lot to be split is a historic property or within a historic district that is included on the State Historic Resources Inventory or the lot to be split is within a site that is designated by ordinance as a city landmark or as a historic property or within a historic district.

  • F. Prior urban lot split. The lot to be split was established through a prior urban lot split, or the lot to be split is adjacent to a lot that was established through a prior urban lot split by the owner of the lot to be split or by any person acting in concert with the owner.

    1. Housing that is income-restricted for households of moderate, low, or very low income.

    2. Housing that is subject to any form of rent or price control through a public entity's valid exercise of its police power.

    3. Housing, or a lot that used to have housing, that has been withdrawn from rental or lease under the Ellis Act (Government Code Sections 7060 through 7060.7 ) at any time in the 15 years prior to submission of the urban lot split application.

    1. Either resulting lot is more than 60% or less than 40% of the original lot area.
  • I. Unit count. Either or both of the resulting lots will have more than two units. For purposes of this section, a "unit" is any type of dwelling, including but not limited to an ADU or JADU, except to the extent such definition is determined to be inconsistent with Government Code Section 66411.7 .

  • J. Easements. The applicant does not convey all easements required for the provision of public services and facilities.

  • K. Specific adverse impacts. If the Director makes a written finding, based on a preponderance of the evidence, that the project would have a "specific, adverse impact" on either public health and safety or on the physical environment and for which there is no feasible method to satisfactorily mitigate or avoid the specific adverse impact.

    1. A specific adverse impact includes, but is not limited to, the following:

      • a. The subdivision or development within the MSHCP Area, which is based on the specific and defined environmental impacts on protected species and habitat, as well as established procedures for mitigating and avoiding such impacts as set forth in the MSHCP.

      • b. Any lot split which results in a driveway or other vehicular access that does not provide safe access into traffic or onto the lot from traffic.

    2. Because Government Code Section 66411.7 precludes the City from requiring any dedication of rights-of-way or construction of offsite improvements, the Director shall deny any application where either dedication of rights-of-way and/or construction of offsite improvements is necessary to satisfactorily mitigate a specific adverse impact, including but not limited to where a subdivision or development of property would otherwise require a dedication for sidewalk, parkways, curbs, gutters, street and road improvements or other traffic improvements.

    3. The City Council may establish additional guidelines that set forth circumstances where a project will have a specific adverse impact on either the public health and safety or on the physical environment. Nothing herein shall hinder or constrain the Director's discretion to make written findings, based on a preponderance of the evidence, that a project would have a specific adverse impact on either public health and safety or on the physical environment and for which there is no feasible method to satisfactorily mitigate or avoid the specific adverse impact.

  • M. No legal requirement. If for any reason, including but not limited to repeal of Government Code Section 66411.7 , initiative or referendum, court decision or any circumstance in which Section 66411.7 does not obligate the ministerial approval of an urban lot split, or if for any reason the Director is not required to ministerially approve an urban lot split.

§ 17.905.040. Standards Specific to Urban Lot Splits.

  • A. Applicability. The following development standards shall apply to urban lot splits subject to approval under this chapter.

  • B. Lot access. Each resulting lot must have direct access to the public right-of-way, which shall be shown on the tentative and final map.

  • C. Unit quantity. No more than two units of any kind are permitted on any lot created by an urban lot split.

  • D. Unit size. Notwithstanding any other providing of the Development Code, a unit other than an ADU or JADU on any lot resulting from an urban lot split shall be limited as follows:

    1. The total floor area of each residential unit developed on a lot to be split must be less than or equal to 800 square feet and more than 500 square feet.

    2. A primary dwelling that was legally established prior to the urban lot split and that is larger than 800 square feet in floor area is limited to the lawful floor area and structural footprint at the time of the urban lot split. It may not be expanded.

    3. A primary dwelling that was legally established prior to the urban lot split and that is smaller than 800 square feet in floor area may be expanded to 800 square feet in floor area after the urban lot split.

  • E. Setbacks.

    1. Subject to Subsections E.2 and 3 below, development on either or both of the resulting lots does must comply with all standard setbacks for its location.

    2. Only to the extent necessary to avoid a conflict with Government Code Section 66411.7 , no setback is required for an existing legally established structure or for a new structure that is constructed in the same location and to the same dimensions as an existing legally established structure.

    3. A unit may encroach into the side or rear setback only if strict application of the setback standard would have the effect of physically precluding the construction of two units of up to 800 square feet on a resulting parcel, in which case the encroachment into the setback shall be only as necessary to enable construction of the unit or units at a maximum size of 800 square feet. However, in no event may any unit be constructed without at least providing a four foot setback from the side and rear lot lines.

  • F. Parking. Subject to Government Code Section 66411.7(e)(3)(A) and (B) , each new primary dwelling unit that is built on a lot after the urban lot split must provide at least one off-street parking space per unit. This section does not preclude an applicant from complying with the City's standard parking requirements.

  • G. Utilities. Each dwelling unit on the resulting lots must have its own direct utility connection to the utility service provider.

  1. For each dwelling unit on the resulting lots that is or that is proposed to be connected to an onsite wastewater treatment system, the applicant must: 1) demonstrate that each primary dwelling unit will have its own septic tank and leach line; 2) submit a percolation test completed within the last five years or, if the percolation test has been recertified, within the last 10 years. This section shall not be interpreted to allow an onsite water treatment system where a sewer connection is available or where the property is required to connect to sewer.
