Mill Valley City Zoning Code

CHAPTER 20

80 AFFORDABLE HOUSING REQUIREMENTS

§ 20.80.010 Findings.

A. 
Mill Valley is experiencing a housing shortage for affordable households. Increasingly, persons with extremely low, very low, low and moderate incomes who work and live within the City are unable to locate housing at prices they can afford and are increasingly excluded from living in the City.
B. 
The shortage of affordable housing in Mill Valley is detrimental to the public health, safety and welfare.
C. 
A goal of the City, as expressed in the Mill Valley General Plan, is to achieve a balanced community with housing available for households of a range of income levels. State law requires the City to make an adequate supply of housing available for persons of all economic segments of the community.
D. 
The high cost of newly constructed housing does not, to any appreciable extent, provide housing affordable to extremely low, very low, low and moderate income households, and new market-rate development which does not include nor contribute toward lower cost housing, further aggravates the current housing problems by reducing the supply of developable land.
E. 
The demolition and replacement or construction of new market-rate housing has a deleterious impact on affordable housing opportunities in the City, by displacing current tenants and occupants, by replacing smaller, older and more affordable units with larger and more expensive housing, and by reducing the supply of vacant or developable land in the City.
F. 
In order to meet the goals and objectives described in the General Plan, it is necessary that the City establish the Housing Trust Fund to fund City efforts to create affordable housing opportunities within the City.
G. 
All new market-rate residential development in the City must provide affordable opportunities to City residents or pay a fee to mitigate the impacts of the development on affordable housing opportunities in the City.
(Ord. 1295, September 5, 2017)

§ 20.80.020 Purpose and intent.

A. 
The purpose of this chapter is to enhance the public welfare and assure that all residential development projects proportionately contribute to the City's housing goals by constructing affordable unit(s) or pay a fee aimed at developing, constructing and/or maintaining affordable housing unit(s) in Mill Valley.
B. 
The provisions of this chapter are intended to:
1. 
Implement the Housing Element of the General Plan, and the requirements of state law (Government Code Section 65915, et seq.).
2. 
Maintain a balanced community with a wide variety of housing available to households of all income levels.
3. 
Increase the supply of affordable housing units.
4. 
Increase the supply of housing for the disabled, seniors, and other households with special housing needs, as defined in the Housing Element.
5. 
Address the need for affordable housing related to the increase in jobs and services associated with new and/or expanded market rate residential development.
6. 
Provide affordable housing units that are compatible in character and quality with their surrounding neighborhoods.
7. 
Maintain the physical condition and affordability of units produced through the provisions of this chapter over time.
8. 
Protect and maintain the existing affordable housing units within the City's existing housing stock.

§ 20.80.050 Applicable projects.

A. 
Summary. Development projects include single family, multi-family and mixed-use residential construction within a 24-month period (further defined in Section 20.80.040), including such projects as renovations, additions, new unit(s); and replacement unit(s).

1. 
Renovations and Additions to Existing Dwelling Unit(s) Less Than the Construction Valuation Threshold.

C. 
Projects Subject to Impact Fees. Residential development projects which meet or exceed the construction valuation threshold, are subject to the following impact fees:
1. 
Single Family Development Projects. Single family development projects including renovations and additions to existing single family residences and new or replacement units that meet or exceed the construction valuation threshold shall pay the impact fee, as set forth in Section 20.80.070. The impact fee shall be calculated based on a percentage of the construction valuation, as established by City Council resolution.

The impact fee shall be calculated based on a percentage of the construction valuation, as established by City Council resolution.
To ensure compliance with the Costa Hawkins Act (Chapter 2.7 of Title 5 of Part 4 of Division 3 of the Civil Code), the City may only approve a proposal to provide rental affordable units if the applicant agrees in a recorded agreement with the City to limit rents in consideration for a direct financial contribution or a form of assistance specified in Chapter 4.3 (commencing with Section 65915) of Division 1 of Title 7 of the Government Code. Such a proposal must be made by the applicant and not by the City, in the event that a court finds that this subsection would violate the Costa-Hawkins Act, the court shall sever this subsection from the remainder of this chapter, and the remainder of this chapter including, but not limited to, the requirement that an applicant pay the affordable housing impact fee shall remain in full force and effect.
D. 
Projects Subject to Providing Affordable Housing Units. The primary intent of the inclusionary requirement is to achieve the construction of new affordable units, as outlined in this chapter and as consistent with state and federal law. Other alternatives of equal value, such as, but not limited to, payment of the impact fee, acquisition and rehabilitation of existing units, construction of affordable units off site or the transfer of sufficient land and/or cash to the City or non-profit housing organization or housing developer to develop the required number of affordable units may be considered at the sole discretion of the City.
1. 
Multi-Family Rental and Ownership Units (Four or More New or Replacement Units). Multi-family and mixed use ownership projects of four or more units shall construct affordable housing unit(s) as follows:
a. 
Affordable Housing Units. At least 25% of the total number of dwelling units within a project that creates four or more new units shall be made available to moderate and low income households. Of these designated affordable units, at least 50% shall be rented or sold to low income households.
b. 
Fractions. Fractional numbers of inclusionary units are "rounded up" to the nearest whole integer and treated as a whole inclusionary unit; alternatively, the requirements of this section may be satisfied through payment of the impact fee, applied to remaining fractional number, and calculated based on a percentage of construction valuation for the project, as stipulated in Section 20.80.050(C).
c. 
Conditions of Approval. Any discretionary approval of new dwelling units shall have conditions attached which will assure compliance with the provisions of this chapter. Such conditions shall:
i. 
Specify the timing of payment of the impact fee and/or the construction of the affordable units, the number of inclusionary units and the appropriate income and purchase price or rental restrictions, and amenities associated with each unit.
ii. 
Require an affordable housing agreement providing for long-term affordability, income certification and screening of potential purchasers and/or renters of inclusionary units, resale control mechanism and on-going management of the affordable units.
iii. 
Contain a provision indicating that residents of affordable units shall not be denied access to common open spaces or recreational amenities.
iv. 
Where an applicant elects to initially rent all of the units in a residential ownership project, the affordable housing agreement shall provide affordable rents for the affordable unit(s) during the rental period.
2. 
Alternative to Building Affordable Units On-Site. Where feasible, it is the preference of the City that the requirements of this section be met through the construction of affordable units within the project. Construction of affordable units within another site or sites within the City may be approved on a case-by-case basis through the City's discretionary process; or upon finding by the Planning Commission or City Council that the construction of the required affordable units is not feasible or appropriate as part of the project or elsewhere in the City, the City may allow the applicant to satisfy the requirements of this section through the payment of the impact fee set forth in Section 20.80.070 for the new construction or the donation of land at the sole discretion of the City as provided below.
a. 
Land Donation. At the sole discretion of the City, applicants may satisfy the requirements of this chapter by an irrevocable offer of dedication of land for construction of affordable housing within the City.
i. 
Identification of the land to be dedicated shall be accomplished prior to approval of the discretionary permit for the residential development permit project.
ii. 
In addition to any other findings required by statute, ordinance, or otherwise, any project approval for an in-lieu land dedication shall include a finding that the land to be dedicated is not subject to liens, is served or proposed to be served by municipal services, including water, sewer, roads, electricity, telephone or other similar customary services, and contains no unusual planning or development constraints.
iii. 
Land for affordable housing projects shall be dedicated to either for-profit or non-profit affordable housing builders only, subject to an affordable housing agreement or other legal contract approved by the City Council that shall provide for the construction of affordable units and the long-term affordability, management, and maintenance of the units. The amount of land shall be at least as much as necessary to provide one and one-half times (150%) the required number of affordable units as stipulated in this chapter. The City Council may, in its sole discretion, approve, conditionally approve or reject such offer of dedication. Rejection of an offer of dedication of land under this section shall not relieve an applicant of the obligation to comply with this chapter through another means.
iv. 
Prior to City approval of the options set forth in this subsection, the City must find that the dedication of land will provide an equivalent or greater number of affordable units than would otherwise be required by this chapter consistent with any environmental constraints of the site.
b. 
Off-Site Units. Where provided for, applicants may satisfy the requirements of this chapter by constructing affordable units on another site within the City.
i. 
New inclusionary units not built on the site of the proposed original project shall be constructed simultaneously with market-rate dwellings constructed on the original site, unless alternative arrangements are approved as part of the project approval.
ii. 
The City may approve off-site rental affordable units be provided in lieu of ownership units.
iii. 
Where inclusionary units are permitted off-site, such units do not count as affordable units for the purpose of receiving a density bonus, as outlined in Chapter 20.81.
iv. 
In addition to any other findings required by state law or city ordinance, any approval of the linked project shall include a finding that the off-site inclusionary units shall be equivalent or greater in number than what would otherwise be required under this chapter, consistent with any environmental constraints of the site.

Lnclusionary units and impact fees are not considered to be mutually exclusive, and a project may create inclusionary units and pay impact fees, so long as the total amount of units and fees shall not exceed the cost of mitigating the impact on affordable housing in the City as described in this chapter.
9. 
Fractional requirements may be satisfied by the construction of an additional affordable unit or payment of the affordable housing impact fee by applying the fractional remainder to the construction valuation, and applying the fee accordingly.
B. 
Affordable Housing Trust Fund. The purpose of the affordable housing fund is to receive and disburse affordable housing impact fee revenues and other housing funds to address the housing needs of affordable households in the City. Separate accounts within such housing fund may be created from time to time to avoid commingling if required by law or as deemed appropriate to further the purposes of the housing fund.
1. 
All affordable housing impact fees shall be deposited into the affordable housing fund.
2. 
The affordable housing trust fund, including accrued interest, shall be subject to all the applicable provision of the Mitigation Fee Act, including, but not limited to, the requirements for accounting, reporting and expenditure of the fund to increase the supply of affordable housing in Mill Valley.
3. 
The fees collected under this chapter and all earnings from investment of the fees shall be expended exclusively to provide or assure continued provision of affordable housing in the City to meet the housing needs of the City's workforce through acquisition, construction, development assistance, substantial rehabilitation or maintenance, financing, rent or other subsidies, or methods, and for costs of administering programs which serve those ends. The housing shall be of a type, or made affordable at a cost or rent, for which there is a need in the City and which is not adequately supplied in the City by private housing development in the absence of public assistance and to the extent feasible shall be utilized to provide housing opportunities to affordable households.
4. 
Housing assisted with affordable housing impact fees shall be subject to long-term affordability covenants established through an affordable housing agreement.
5. 
Prior to the distribution of funds, guidelines and administrative procedures shall be approved by City Council resolution, outlining the application, review, scoring/ranking or priority setting, distribution and use of trust fund monies.

§ 20.80.080 Other affordable housing incentives.

It is the intent of this chapter that the requirements for affordable units shall not be determined by the availability of government subsidies. This is not to preclude the use of such programs or subsidies, if available. This chapter is also not intended to be an undue burden on the developers of residential projects. Therefore, as detailed below, the following provisions may be granted in association with the construction of affordable units.
A. 
Density Bonus. Applicants constructing affordable units within a project may apply for concessions outlined in Chapter 20.81, Density Bonus, if eligible.
B. 
Modification to Total Number of Units. The City may consider requests to reduce the total number of required moderate income inclusionary units within a project, or increase the number of market rate units, if some or all of the inclusionary units are sold or rented at prices affordable to very low or low income households.
C. 
Modification to Amenities in Affordable Units. The City may consider requests to modify the amenities in affordable units, provided that additional inclusionary units are built or the level of affordability associated with the affordable units is adjusted from moderate income to low or very low income households.
D. 
Planned Development Combining District. Should a proposed project exceed the required number of inclusionary units set forth in this chapter, an applicant may apply for the use of a planned development zoning designation as part of the project.
1. 
The planned development zoning designation, as outlined in Chapter 20.57 allows the City and applicant to review and assess development standards for an established Zoning District, which may be of particular impact, value and benefit to the entire community, such as providing additional affordable units.
2. 
A Planned Development Combining District request cannot be used in combination with density bonus regulations set forth in Chapter 20.81.
E. 
Fee Waivers. In the attempt to avoid any undue burden on developers who are required to provide inclusionary units under the provisions of this chapter, the City may waive or reduce park dedication, development fees, and other City fees applicable to the inclusionary units in the project.
F. 
Technical Assistance. In order to emphasize the importance of securing low and very low income housing as a part of this program, City staff, other agencies, or designated consultants may provide advice on financial subsidy programs to applicants. During individual project review, the City may request that the applicant provide an economic analysis which will indicate the most suitable methods for the implementation of the requirements of this chapter. This is to be done with the objective of increasing the feasibility and lowering the cost of units affordable to moderate, low, and very low income households.

A. 
Purpose. A Housing Advisory Committee shall be created for the purpose of assisting staff and advising the City Council (and Planning Commission) on matters relating to the Housing Element of the General Plan and the Affordable Housing Ordinance.
B. 
Appointment. The Housing Advisory Committee shall be appointed by the City Council. Members shall reside or work within the City. Term of service and number of individuals serving on the Housing Advisory Committee shall be outlined in the Committee by-laws, established in subsection C.

§ 20.80.100 Enforcement.

A. 
Except as provided herein, no building permit or occupancy permit shall be issued, nor any development approval granted, for any project which does not meet the requirements of this chapter.
B. 
In addition to, or in lieu of, the provisions of subsection A of this section, the City may institute appropriate legal actions or proceedings including, but not limited to, equitable relief for the enforcement of any affordable housing agreement or the requirements set forth in this chapter.
(Ord. 1295, September 5, 2017)

§ 20.80.110 Appeals.

A. 
Any person aggrieved by any action involving denial, suspension or revocation of a building or occupancy permit or denial, suspension or revocation of any development approval may appeal such action or determination to the Planning Commission, with further appeal possible to the City Council by filing a written appeal to the Director of Planning and Building and paying the appropriate application fees.
B. 
As part of an application for the approval of a residential project, an applicant may apply for a reduction, adjustment, or waiver of the requirements of this chapter based upon a showing, based on substantial evidence, that there is no reasonable relationship between the impacts of the project and the requirements of this chapter, or that applying the requirements of this chapter would result in an unconstitutional taking of property or would violate a provision of state or federal law. The applicant shall set forth in detail the requisite evidence to demonstrate the alleged unlawful result.
(Ord. 1295, September 5, 2017)

§ 20.80.120 Consistency with state law and severability.

The provisions of this section are intended to comply with California Government Code Section 65915, the Mitigation Fee Act at Government Code Section 66000, et seq., and state and federal law. In the event that any provision of this section conflicts with state or federal law applicable to the City, state or federal law shall apply. The provisions of this section are declared to be separate and severable. The invalidity of any clause, sentence, paragraph, subdivision, section, or portion of this section, or the invalidity of the application thereof to any person or circumstances shall not affect the validity of the remainder of this section, or the validity or its application to other persons or circumstances.
