17.138.040 – General Standards

  • A. Methods of Meeting Requirements. New development projects shall satisfy the inclusionary housing requirements, as specified in Tables 2 and 2A of the General Plan Housing Element (also included below) which require that all nonexempt development projects shall contribute toward the production of affordable housing by constructing at least one affordable dwelling unit or paying an in-lieu fee. To meet the requirements, the developer shall comply with one or more of the following methods:

    1. Construct the required number of affordable dwelling units, as specified in Table 2 of the Housing Element, as adjusted by Table 2A of the Housing Element; or

    2. Pay an in-lieu fee as described in Table 2, as adjusted by Table 2A. For development projects in which the adjustment factor under Table 2A equals zero (“0”), the minimum adjustment factor shall be 0.25 (resulting in a minimum in-lieu fee of 1.25 percent of the building valuation for development projects and commercial developments in expansion areas, and 3.75 percent of building valuation for residential developments in expansion areas); or

    3. Dedicate real property for affordable housing; or

    4. Provide for the rehabilitation of existing housing units that are vacant and in poor physical condition or are otherwise uninhabitable; or

Notes:

  1. Including allowed density bonus, where applicable.

  2. Multiply the total base Inclusionary Housing Requirement (either housing or in-lieu percentage) by the adjustment factor to determine requirement. At least one enforceably restricted affordable unit is required per development of five or more units.

  • B. Affordable Housing Standards . Affordable dwelling units constructed must meet City affordable housing standards and must be consistent with affordability policies in the General Plan Housing Element.

  • C. Concurrent Development. The required inclusionary units shall be constructed concurrently with market value units unless the developer and the Director agree within an affordable housing agreement to an alternative development schedule.

17.138.050 – Procedures

  • A. Fractional Numbers. In determining the number of dwellings that are required to be built pursuant to Table 2, fractional units shall be rounded up to the next higher whole number unit.

  • B. Determining Adjustment Factor Using Project Density and Average Unit Size. To determine the adjustment factor in Table 2A, project density shall be calculated by dividing the total number of density units proposed (including density bonus where applicable) by the development project site’s net area. Average floor area shall be calculated by dividing the total gross floor area of all dwellings (excluding garages) within the development project by the total number of dwellings. Dedicated open space shall not be included in a site’s net area.

  • C. Mixed-Use Development Projects. For mixed-use development projects with five or more dwellings, the inclusionary housing requirement is determined by: (1) using Table 2 to calculate the base inclusionary requirement for the commercial use, and (2) using Table 2A to adjust the base requirement based on project density and average unit size, as described in subsection (B) of this Section. For mixed-use development projects with fewer than five dwellings, the base inclusionary housing requirement for the commercial use shall apply.

  • D. Timing. The inclusionary housing requirement shall be met prior to issuance of a Certificate of Occupancy for the first unit in a building, or the first building in a complex to be constructed or remodeled; or for subdivisions, prior to Final Map approval; or prior to building permit issuance, for projects for which a Certificate of Occupancy is not issued; or as otherwise agreed to by the Director as part of tentative map, rezoning, Minor Use Permit, Conditional Use Permit, or other development approval.

  • E. Affordable Housing Agreement. To meet the requirement, the developer may enter into an agreement with the City, the Housing Authority of San Luis Obispo (HASLO), nonprofit housing provider, or other qualified housing provider approved by the Director to construct, refurbish, convert, operate, and maintain the required affordable housing. Such affordable housing agreements shall be to the approval of the Director and shall be in a form approved by the City Attorney.

17.138.060 – In- ~~ Lli ~~ eu Housing Fee

  • A. Payment of In-Lieu Fee. The developer may, at his or her discretion, choose to pay a fee to the City in lieu of constructing affordable dwellings to meet this requirement.

  • B. Amount and Method of Payment. The dollar amount and method of payment of the in-lieu fee shall be as described in Table 2 of Appendix N of the General Plan Housing Element, and where applicable, as adjusted by Table 2A in Appendix N of the General Plan Housing Element, as further described in Section 17.xxx.xx, to the approval of the Director. For subdivisions in which the construction valuation is not known, the Director shall estimate the average construction valuation based on lot area, land value, and applicable City development standards. The developer shall use the estimated average construction valuation to determine the amount of inlieu fees.

  • C. Timing. In-lieu fees shall be paid prior to release of occupancy of the first dwelling within a residential development; or for residential subdivisions to be built out by others, prior to final subdivision map approval; or prior to occupancy for new commercial buildings or remodels; or prior to building permit issuance, for projects for which a certificate of occupancy is not issued; or as otherwise provided by written agreement between the developer and City, to the approval of the Director. For mixed-use developments, these regulations shall apply to whichever occupancy release is first issued.

17.138.070 – Affordable Housing Fund Established

The City hereby establishes an 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. In-lieu fees collected shall be deposited into the Affordable Housing Fund, to the satisfaction of the Director of Finance.

17.138.080 – Real Property Dedication

  • A. Irrevocable Offer to Dedicate Real Property. At the discretion of the Council, an irrevocable offer to dedicate real property equal or greater in value to the in-lieu fee which would otherwise be required may be offered to the City, or to an affordable housing provider designated by the City, instead of providing the required number of affordable dwellings or paying in-lieu fees. The City shall have the option of negotiating with the applicant regarding dedications of properties with greater value that the in-lieu fee to achieve an equitable dedication. In considering an offer to dedicate real property, the Council must find that the dedication of real property will provide equal or greater public benefit than constructing affordable units or paying in-lieu fees, based on the following criteria and additional criteria set forth in Government Code Section 65915(g)(2)(A-H):

    1. Valuation of the land and/or improvements to be dedicated relative to other methods of meeting the requirement;

    2. Suitability of the land and/or improvements for housing, including General Plan conformity, size, shape, topography, and location; and

    3. Feasibility of developing affordable housing, including General Plan consistency, and availability of infrastructure.

  • B. Real Property Valuation. The valuation of real property offered in lieu shall be determined by the Director, based upon an appraisal made by a qualified appraiser mutually agreed to by the developer and the City. Costs

associated with the appraisal, title insurance and transfer, recordation, and related costs shall be borne by the developer.

  • C. Agreement and Timing. The real property dedication shall be by deed or other instrument acceptable to the City , and shall be completed by recordation through of the Office of County Clerk-Recorder prior to occupancy release of the first residential unit or commercial building in the development; or prior to building permit issuance, for projects for which a Certificate of Occupancy is not issued; or as otherwise provided by written agreement between the developer and the City.

  • B. Affordable Housing Agreement. Any incentives provided by the City, beyond those incentives to which a developer may be automatically entitled to under Chapter 17.14 0 Section 17.xx.xxx (Affordable Housing Incentives) shall require Council approval and shall be set out in an affordable housing agreement.
