17.138.040 Inclusionary housing requirements.

A. General Requirements. All nonexempt residential development projects shall include inclusionary units as required by this chapter. If the calculated number of units results in a fraction, the number shall be rounded as described in Section 17.138.080(A).

  1. Construct the required number of inclusionary units for residential or mixed-use projects;

  2. Pay an in-lieu fee for residential or mixed-use projects; or

  3. Pay a commercial linkage fee (see Chapter 4.60) for new nonresidential or nonresidential portions of mixed-use project(s).

B. Residential Requirements.

  1. Ownership Dwelling Units. Ten percent of the dwelling units (see Section 17.138.080(A)) shall be made available for sale to eligible households with five percent for low-income households (fractional units may be rounded down to the next whole number) and five percent for moderate-income households (fractional units may be rounded up to the next whole number). See Section 17.138.080(A) for more information regarding fractional numbers.

  2. Rental Dwelling Units. Six percent of the dwelling units (see Section 17.138.080(A), Fractional Numbers) shall be made available for rent to eligible households with three percent for very low-income households (fractional units may be rounded down to the next whole number) and three percent for low-income households (fractional units may be rounded up to the next whole number).

  3. In-Lieu Housing Fees. An applicant may pay in-lieu fees to the city rather than construct inclusionary units on site for residential projects (see Section 17.138.060, In-Lieu Housing Fee).

C. Nonresidential Requirements.

  1. Commercial, Office, Service, Hotel, Retail, Industrial, and Institutional Uses. An applicant shall pay a commercial linkage fee based on the gross square footage of the nonresidential space in accordance with Chapter 4.60.

D. Mixed-Use Development Requirements.

  1. Dwelling Units and Commercial Space. For mixed-use development, the inclusionary housing requirement is determined in accordance with subsection B of this section for all dwelling units in addition to subsection C of this section for all new commercial square footage within the development project. For example, a for-rent mixed-use project includes twenty residential units and five thousand square feet of commercial space: the inclusionary requirement would be two affordable units (twenty times six percent equals one and one-fifth rounded to two) and a commercial linkage fee would be applied to the five thousand square feet of commercial space. (Ord. 1719 § 3, 2022)

17.138.050 Standards for inclusionary units.

A. Standards. Inclusionary units must meet the following standards:

  1. Inclusionary units shall be dispersed throughout the residential development projects to prevent a concentration of affordable units within the development project.

  2. Inclusionary units shall be consistent with the design of market rate units in terms of exterior appearance, materials, and finished quality.

  3. The applicant may reduce square footage of inclusionary units as compared to the market rate units as long as the minimum square footage of the affordable units is no less than seventy-five percent of the average size of all market rate units in the residential development project with the same bedroom count. For the purpose of this subsection, the “average size” of a unit with a certain bedroom count equals the total square footage of all market rate units with that bedroom count in the residential development project divided by the total number of market rate units with the same bedroom count in the residential development project.

  4. For residential development projects with multiple market rate unit types containing differing numbers of bedrooms, inclusionary units shall be representative of the market rate unit mix. For example, a for-sale residential project includes fifty dwelling units; ten three-bedroom units, twenty two-bedroom units, and twenty one-bedroom units. To represent the units within the residential project, the five required inclusionary units would be one three-bedroom, two two-bedrooms and two one-bedrooms.

  5. The required inclusionary units shall be constructed concurrently with market rate units, unless an alternative development schedule is otherwise stipulated by the applicable review authority of the residential development project.

  6. Inclusionary units shall be subject to the city’s and/or the administrator’s fee schedule in accordance with Section 17.138.110. (Ord. 1719 § 3, 2022)

Exceptions & meaning →

17.138.060 In-lieu housing fee.

A. Payment of In-Lieu Fee. The developer may, at their discretion, choose to pay a fee, as established by a resolution of the city council, to the city in lieu of constructing affordable units to meet their inclusionary housing requirement.

B. In-Lieu Fee Calculation. In-lieu fees shall be calculated using the new habitable square footage, as defined by California Building Code, included within the residential development project.

C. Affordable Housing Fund. All in-lieu fees collected shall be deposited into the affordable housing fund. The fund shall be administered by the finance director and shall be used exclusively to provide funding for the provision of affordable housing and for reasonable costs associated with the development of affordable housing, at the discretion of the council.

D. Timing. In-lieu fees shall be paid prior to building permit issuance. For projects constructed in phases, in-lieu fees shall be paid in the proportion that the phase bears to the overall project. (Ord. 1719 § 3, 2022)

Exceptions & meaning →

17.138.070 Inclusionary housing plan.

A. Application Requirements. An applicant proposing a project for which inclusionary housing is required shall submit a statement with their planning application or building permit (whichever applies), describing the project’s inclusionary housing plan. The statement shall include:

  1. A project description that includes details regarding the proposed residential development project such as, but not limited to, total number of dwelling units, number of bedrooms per dwelling unit, square footage of all units (both residential and commercial), type of project (rental or ownership), etc.;

  2. A description of the inclusionary housing plan for each construction phase, including the method chosen to meet the inclusionary housing requirement and including all of the following information including but not limited to:

a. Whether the unit is for sale or rental;

b. The number, location, unit type, tenure, number of bedrooms and baths, floor plan, construction schedule of all inclusionary units;

c. Preliminary calculation of in-lieu fees or commercial linkage fee as applicable;

Exceptions & meaning →

17.138.080 Procedures.

A. Fractional Numbers. In determining the number of dwellings that are required to be built pursuant to Section 17.138.040(B), if the number of required inclusionary dwellings results in a fractional unit, an applicant may pay the in-lieu fee for the fractional unit or provide an additional affordable unit in the project (based on the unit affordability for the type of project). The in-lieu fee for fractional units shall be calculated as described in Table 8-1 (Fractional Inclusionary Requirement Scenarios):

Table 8-1: Fractional Inclusionary Requirement Scenarios

Example Project: 25 Units (i.e., 1,000 sq. ft. per unit) Inclusionary Housing Requirement Option 1 Option 2 Option 3
For-Sale (10%) 1 2.5 units 1 2 Moderate 1 Low Pay in-lieu fee 3 1 Moderate 1 Low Pay fractional in-lieu fee 4
For-Rent (6%) 2 1.5 units 2 1 Low 1 Very-low Pay in-lieu fee 3 1 Low Pay fractional in-lieu fee 4

Notes:

1Five percent for low-income households (rounded down to the next whole number) and five percent for moderate-income households (rounded up).

2Three percent for very low-income households (rounded down) and three percent for low-income households (rounded up).

3In-lieu fee is calculated by the habitable area of the project multiplied by the in-lieu fee as established by the city’s comprehensive fee schedule.

4Fractional in-lieu fee amount is calculated by the remaining fractional inclusionary requirement (i.e., 0.5) multiplied by the in-lieu fee cost per square foot, and then multiplied by the habitable area of the project (excluding the area of any inclusionary units that are provided in the project).

(For-Sale Example: (0.5 x in-lieu fee) x 23,000 sq. ft. = Fractional in-lieu fee amount)

B. Affordable Housing Agreement. The applicant shall complete and sign an affordable housing agreement.

  1. Submittal of an Affordable Housing Agreement. Applicants of residential development projects subject to this chapter shall submit an affordable housing agreement on forms provided by the city and pay a processing and recordation fee.

  2. Timing. All building permits for inclusionary units in a residential development project shall be issued concurrently with, or prior to, issuance of building permits for the market rate units.

  3. Construction Schedule. The inclusionary units shall be constructed concurrently with, or prior to, construction of the market rate units, unless otherwise stipulated by the applicable review authority of the residential development project. Occupancy permits and final inspections for inclusionary units in a residential development shall be approved concurrently with, or prior to, approval of occupancy permits and final inspections for the market rate units.

  4. Review and Approval. The draft agreement shall be reviewed by the director and city attorney for compliance with project approvals, city policies and standards, and applicable codes. Following approval and signing of the agreement by the parties, the final agreement shall be recorded, and relevant terms and conditions shall be recorded as a deed restriction on those lots or affordable units subject to affordability requirements. The affordable housing agreement shall be binding to all future owners and successors in interest.

  5. Term. The affordable housing agreement shall ensure that affordability is maintained for the longest period allowed or required by state law, but not less than forty-five years for ownership and fifty-five years for rental.

  6. Exemption for In-Lieu Fee Payment. An affordable housing agreement shall not be required for projects which meet their inclusionary housing requirement through the payment of in-lieu fees. (Ord. 1719 § 3, 2022)

Exceptions & meaning →

17.138.090 Eligibility requirements.

A. Program Requirement. Only households qualifying as extremely low, very low, low, or moderate income, pursuant to the affordable housing standards, shall be eligible to rent, purchase, or occupy inclusionary units developed or funded in compliance with this chapter. For-sale inclusionary housing units shall be owner-occupied for the term of the affordable housing agreement.

B. Eligibility Screening. The city or an administrator designated by the city shall screen prospective renters or buyers of affordable units. Buyers of affordable units shall enter into an agreement with the city. Occupants must be selected by means of an open, public process which ensures that individuals of a group of interested participants are selected in accordance with the city’s BMR ownership and rental housing guidelines. Private selection of individuals by project owners is not permitted for any affordable units. (Ord. 1719 § 3, 2022)

17.138.100 Shared equity purchase program.

When a residential development project includes affordable housing units for sale in excess of the inclusionary housing requirement for the project, the additional units may be offered under the shared equity purchase program.

A. Under this program, the qualified buyer of a designated affordable dwelling unit shall enter into a shared equity agreement with the city. Said agreement shall be recorded as a lien against the purchased property, at no interest, securing and stating the city’s equity share in the property. The city’s equity share shall be calculated by the director, and shall be the decimal percentage of the property’s value resulting from:

  1. The difference between the property’s market value and the actual price paid by the homeowner, divided by the market value; and/or

  2. When applicable, the amount of subsidy provided by the city to the homeowner to purchase the property, divided by the property’s market value.

B. Upon sale, the city’s equity share shall be repaid to the city from the proceeds of the sale, less the city’s percentage share of title insurance, escrow fees, and documentary transfer taxes, at the close of escrow. The proceeds from the sale shall be deposited into the city’s affordable housing fund and shall be used for the purposes set forth in Health and Safety Code Section 33334.2(e).

C. In the event of “early resale,” owners of properties subject to the shared equity purchase program shall either: (1) pay an equity recapture fee to the city as described in the schedule below, in addition to the city’s equity share, or (2) sell the property to another eligible household.

If the owner chooses to pay the equity recapture fee, the recapture fee shall be paid to the city upon resale at close of escrow, based on the following schedule:

Table 8-2: Percent of Equity Build-up Recaptured

Year % of Equity Build-up Recaptured

Table 8-2: Percent of Equity Build-up Recaptured

Year % of Equity Build-up Recaptured
