(Ord. 16-2149, § 8, 2016)


19.56.030 Density Bonus.

A. Housing developments that meet the criteria in Section 19.56.020A(1) and Section 19.56.020C, if applicable, are eligible for a maximum density bonus as set forth in Table 19.56.030.

19.56.040 Incentives or Concessions, Waivers and Reduction of Parking Standards.

  1. Incentives or Concessions:
    1. A housing development is eligible for incentives or concessions as shown in Table 19.56.040A. Incentives or concessions must be selected from only one category (very low, low, or moderate). No incentives or concessions are available for land donation or for a senior citizen housing development that is not affordable. Condominium conversions and day care centers may have one incentive or concession, or a density bonus, at the City's option, but not both.

      1. A reduction of development standards or a modification of zoning code requirements or architectural design requirements that exceed the minimum building standards approved by the California Building Standards Commission as provided in Part 2.5 (commencing with Section 18901) of Division 13 of the Health and Safety Code, including but not limited to, a reduction in setback requirements, square footage or parking requirements, such that the reduction or modification results in identifiable, financially sufficient, and actual cost reductions.
      2. Approval of mixed-use zoning in conjunction with the housing development if commercial, office, industrial or other land uses will reduce the cost of the housing development, and if the commercial, office, industrial or other land uses are compatible with the housing development and the existing or planned development in the area where the proposed housing development will be located;
      3. Other regulatory incentives or concessions proposed by the developer or the City, which result in identifiable, financially sufficient, and actual cost reductions.
    3. Nothing in this section requires the provision of direct financial incentives for the housing development, including but not limited to the provision of financial subsidies, publicly owned land by the City or the waiver of fees or dedication requirements. The City, at its sole discretion, may choose to provide such direct financial incentives;
    4. A housing development which requests incentives or concessions must demonstrate, in compliance with Section 19.56.060B, that the requested incentives or concessions are required to provide for affordable rents or affordable housing costs, as applicable.
  2. Waivers:
    1. An applicant may submit to the City a proposal for the waiver or reduction of development standards that will have the effect of physically precluding the construction of a housing development meeting the criteria outlined in Section 19.56.020 at the densities or with the concessions or incentives permitted under this chapter.
    2. A proposal for the waiver or reduction of development standards shall neither reduce nor increase the number of incentives or concessions to which the applicant is entitled to subject to Section 19.56.040A.
    3. The applicant shall demonstrate that the development standards that are requested to be waived will have the effect of physically precluding the construction of the development with the density bonuses and incentives or concessions.
  3. Reduction of Parking Standards:
    1. If a housing development is eligible for density bonus as provided in Section 19.56.020, upon request of the applicant, the maximum off-street parking standards that can be applied to the housing portion of the development, inclusive of handicapped and guest parking are indicated in Table 19.56.040B.

19.56.070 Findings.

  1. Before approving an application that includes a request for a density bonus, incentive or concession, waiver or reduction in parking standards, pursuant to this chapter, the decision-making body shall determine that the proposal is consistent with State Law by making the following findings, as applicable:
    1. That the housing development is eligible for the density bonus requested and any incentives or concessions, waivers or reductions in parking standards requested.
    2. That all the requirements included in Section 19.56.030C have been met, if the density bonus is based all or in part on donation of land.
    3. That all the requirements included in Section 19.56.030D have been met, if the density bonus or incentive(s) or concession(s) are based all or in part on the inclusion of a child care facility.
    4. That all the requirements included in Section 19.56.030E have been met, if the density bonus or incentive or concession is based on a condominium conversion.
    5. That the requested incentive(s) or concession(s) will result in identifiable, financially sufficient, and actual cost reductions based upon the financial analysis and documentation provided by the applicant and the findings of the peer-reviewer, if incentive(s) or concession(s) are requested (other than mixed use development).
    6. That the proposed non-residential land uses within the proposed development will reduce the cost of the housing development and are compatible with the housing development and the existing or planned development in the area where the proposed development will be located, if an incentive or concession is requested for mixed use development.
    7. That the development standard(s) for which the waiver(s) are requested would have the effect of physically precluding the construction of the housing development with the density bonus and incentives or concessions permitted, if a waiver is requested.
    8. That all the applicable requirements in Section 19.56.040C have been met, if a reduction in off-street parking standards for an eligible housing development is requested.
  2. If the findings required by subsection (A) of this section, as applicable, can be made, the decision-making body may deny an application for an incentive or concession or waiver requested pursuant to Section 19.56.040 only if one of the following written findings as applicable to each type of application, supported by substantial evidence:
    1. That the incentive or concession, or waiver would have an adverse impact on real property listed in the California Register of Historic Resources; or
    2. That the incentive or concession, or waiver would have a specific, adverse impact upon public health or safety or the physical environment, and there is no feasible method to satisfactorily mitigate or avoid the specific, adverse impact without rendering the residential project unaffordable to low and moderate income households. For the purpose of this subsection, "specific, adverse impact" means a significant, quantifiable, direct, and unavoidable impact, based on objective, identified, written public health or safety standards, policies, or conditions as they existed on the date that the application for the residential project was deemed complete; or
    3. That the incentive or concession, or waiver is contrary to state or federal law.
  3. An application for an incentive or concession may also be denied if the decision-making body makes the written finding, supported by substantial evidence, that the requested incentive or concession is not required to provide for affordable housing costs or affordable rents.
  4. If the findings required by subsection A. of this section can be made, the decision-making body may deny an application for a density bonus or incentive or concession that is based on the provision of child care only if it makes a written finding, based on substantial evidence, that the city already has adequate child care facilities.

D. Provision of Child Day Care Facilities

  1. When a housing development is proposed that contains affordable housing, as provided in Section 19.56.030A and Section 19.56.030C, and includes a child day care facility that will be located on the premises of, as part of, or adjacent to, the project, the City shall grant either of the following if requested by the developer:
    1. An additional density bonus in residential square footage that is equal to or greater than the square footage of the child day care facility.
    2. An additional concession or incentive that contributes significantly to the economic feasibility of the construction of the child day care facility in accordance with Section 19.56.040.
  2. The City shall also require that as a condition of approving the housing development:
    1. The child day care facility shall remain in operation for a period of time that is as long as or longer than the period of time during which the affordable units are required to remain affordable.
    2. Of the children who attend the child day care facility, the children of very low income households, lower income households, or families of moderate income shall equal a percentage that is equal to or greater than the percentage of dwelling units that are required for very low income households, lower income households, or families of moderate income.
  3. Notwithstanding any requirement of Section 19.56.030D, the City shall not be required to provide a density bonus or concession for a child day care facility if the City finds, based upon substantial evidence, that the City has adequate child day care facilities.

E. Condominium Conversions

  1. When an applicant for approval of a condominium conversion agrees to provide at least 33 percent of the total units of the proposed condominium project to low or moderate income households, or 15 percent of the total units of the proposed condominium project to lower income households; to include the affordable units required by Section 19.56.020C, if applicable, and agrees to pay for the reasonably necessary administrative costs incurred by the City, the City shall either:
    1. Grant a density bonus of 25 percent over the number of apartments to be provided within the existing structure or structures proposed for conversion; or
    2. Provide other incentives of equivalent financial value. This shall not require the City to provide cash transfer payments or other monetary compensation but may include the reduction or waiver of requirements that the City might otherwise apply as conditions of conversion approval.
  2. The City may place such reasonable conditions on the granting of a density bonus or other incentives of equivalent financial value as the City finds appropriate. The proposed lower or moderate income units shall be subject to a deed restriction ensuring continued affordability to lower or moderate income households consistent with Section 19.56.050A.
  3. An application shall be ineligible for a density bonus or other incentives under this section, if the apartments proposed for conversion constitute a housing development for which a density bonus or other incentives were previously provided under Government Code Section 65915 or this Chapter.
  4. Nothing in this section shall be construed to require the City to approve a proposal for a condominium conversion. Condominium conversions are subject to the requirements of Chapter 19.116.

F. Density Bonus Calculations:

  1. A density bonus may be selected from only one category listed in Section 19.56.020A(1), except that density bonuses for land donation may be combined with others, up to a combined maximum of 50 percent, and an additional square-foot bonus may be granted for a child day care facility as provided in Section 19.56.030C.
  2. In determining the number of density bonus units to be granted, any fractions of density bonus units shall be rounded up to the next whole number.
  3. Density bonus units authorized by this section shall not be included when determining the number of affordable units required to qualify for the density bonus. In determining the number of affordable units required to qualify for a density bonus, any fractions of affordable units shall be rounded up to the next whole number.
  4. An applicant may request a lower density bonus than the housing development is entitled to, but no reduction will be permitted in the percentage of required affordable units as shown in Section 19.56.020 or Section 19.56.020C.
  5. Regardless of the percentage of affordable units, no housing development will be entitled to a density bonus of more than provided in Government Code Section 65915, unless approved by the City pursuant to Section 19.56.030F(6).
  6. The City, at its discretion, may grant a density bonus higher than the maximum set forth in Table 19.56.030 or in paragraph (5) above to a housing development where all units (except manager’s unit(s)) are affordable to lower income households.
  7. For purposes of calculating a density bonus, the residential units do not have to be based upon individual subdivision maps or parcels. The bonus units shall be permitted in geographic areas of the housing development other than the areas where the affordable units are located.
