Walnut Creek Zoning Code · 2026-06 edition · ingested 2026-07-07 · Walnut Creek

10-2.3.1001 Purpose.

The purpose of this chapter is to provide incentives for the production of housing for extremely low income, very low income, low income, and moderate income households, senior citizens, transitional foster youth, disabled veterans, homeless persons, and low income college students, in accordance with Government Code Sections 65915 through 65918 (State Density Bonus Law).

(§3, Ord. 2240, eff. 7/19/24)

10-2.3.1002 Title.

This article shall be known and cited as the "Density Bonus Ordinance of the City of Walnut Creek" or "Density Bonus Ordinance." (§3, Ord. 2240, eff. 7/19/24)

10-2.3.1003 Density Bonus Entitlement and Incentives.

A. The City shall grant a density bonus and one or more incentives or concessions to any housing development consisting of five (5) or more dwelling units, as and to the extent required pursuant to Section 65915 of the State Density Bonus Law.

B. The City shall grant a density bonus or other incentives of equivalent financial value to applicants for approval to convert apartments to a condominium project, as and to the extent required pursuant to Section 65915.5 of the State Density Bonus Law.

C. A developer may seek approval of a conditional use permit for additional bonus units that exceed the maximum density bonus available under the State Density Bonus Law. If the City grants and the developer accepts such additional bonus units, the additional bonus units shall be considered an incentive or concession.

D. If a developer agrees to construct a housing development that will contain less than the percentage of affordable units required to qualify for a density bonus pursuant to the State Density Bonus Law, the developer may seek approval of a conditional use permit for a density bonus that is proportionally lower than the minimum density bonus specified in the State Density Bonus Law.

E. With the exception of the additional density bonuses for a land donation, child care facility and qualifying affordable housing projects, as provided in this article or under the State Density Bonus Law, each housing development shall be entitled to only one (1) density bonus.

F. Any dwelling unit that would otherwise qualify as a restricted unit that is required to be maintained as an affordable unit pursuant to the City's Inclusionary Housing Ordinance shall also be considered a restricted unit for purposes of determining whether the housing development qualifies for a density bonus.

G. Any density bonus or incentive or concession awarded pursuant to this article shall generally apply only to the particular housing development for which the density bonus or incentive or concession is awarded. A density bonus or incentive or concession may be transferred, credited, or applied to a different housing development only if the City and the developer agree pursuant to an approved density bonus housing agreement.

H. The approval of a density bonus shall not, in and of itself, preclude a housing development from receiving other government subsidies for affordable housing.

I. The approval of a density bonus, incentive or concession, development standard waiver or modification, or parking modification as provided herein, shall not be interpreted, in and of itself, to require a general plan amendment, zoning change, or other discretionary approval. (§3, Ord. 2240, eff. 7/19/24)

10-2.3.1004 Waiver and Reduction of Development Standards.

A developer may seek a waiver or reduction of development standards that will have the effect of physically precluding the construction of a housing development that qualifies for a density bonus at the densities or with the incentives or concessions permitted by this article, as and to the extent required pursuant to Section 65915 of the State Density Bonus Law. The developer must make such request in writing. If the City determines that the requested waiver or reduction does not meet the criteria under Section 65915 of the State Density Bonus Law, and upon the request of a developer, the City shall meet with the developer to discuss such deficiencies and compliance with said criteria in a requested waiver or reduction of City development standards.

Notwithstanding the foregoing, the City shall not be required to approve any request for a waiver or modification of development standards as permitted by Section 65915 of the State Density Bonus Law. (§3, Ord. 2240, eff. 7/19/24)

10-2.3.1005 Density Bonus for Child Care Facilities.

When a developer proposes to construct a housing development that qualifies for a density bonus under Section 10-2.3.1003 and the qualifying housing development includes a child care facility that will be located on the premises of, as part of, or immediately adjacent to, the housing development, and the housing development otherwise meets the requirements under subdivisions (b) and (h) of Section 65915 of the State Density Bonus Law, the City shall grant an additional density bonus and concession or incentive as provided under subdivision (h) of Section 65915 of the State Density Bonus Law and subject to the requirements therein. (§3, Ord. 2240, eff. 7/19/24)

10-2.3.1006 Density Bonus for Qualifying Commercial Projects.

When a developer proposes to construct a commercial development project and has entered into an agreement for partnered housing to contribute affordable housing through a joint project or two (2) separate projects encompassing affordable housing, and such form and content of agreement, joint project and construction to affordable housing, the type of partner housing developer, and the site proposed for housing construction all comply with the requirements of Section 65915.7 of the State Density Bonus Law, the City shall grant a density bonus in accordance with Section 65915.7. For a commercial development project receiving a density bonus pursuant to this section, construction for the affordable housing shall commence in accordance with time lines ascribed by the agreement between the commercial developer and affordable housing partner, or the City shall withhold certificates of occupancy for the commercial development until the partner developer has completed construction of the affordable units. (§3, Ord. 2240, eff. 7/19/24)

10-2.3.1007 Floor Area Ratio Bonus for Qualifying Transit-Adjacent Projects.

When a developer proposes to construct an eligible housing development as defined in Section 65917.2 of the State Density Bonus Law, and that otherwise meets the requirements of that section, the City shall grant a floor area ratio bonus in lieu of a density bonus awarded on the basis of dwelling units per acre, and related incentives or concessions including reduced parking ratios, in accordance with Section 65917.2. In the case of an eligible housing development that is zoned for mixed-use purposes, any floor area ratio requirement under the Zoning Ordinance, General Plan, and any specific plan applicable to the nonresidential portion of the eligible housing development shall continue to apply notwithstanding the award of a floor area ratio bonus pursuant to this section. (§3, Ord. 2240, eff. 7/19/24)

10-2.3.1008 Revised Parking Standards.

Upon the written request of the developer of a housing development that qualifies for a density bonus under Section 10-2.3.1003, the City shall permit vehicle parking ratios, inclusive of handicapped and guest parking, which do not exceed the parking ratios established pursuant to Section 65915(p) of the State Density Bonus Law. (§3, Ord. 2240, eff. 7/19/24)

10-2.3.1009 Affordability Requirements.

All restricted units shall remain affordable in accordance with the requirements of, and for the minimum period required by, the State Density Bonus Law. The required affordability time limit for each restricted unit shall commence upon the issuance of a certificate of occupancy for such restricted unit. The owner of rental restricted units shall provide all notices and rights to tenants required to be given prior to and upon the

expiration of affordability covenants pursuant to Government Code Section 65863.10 or successor statutes. (§3, Ord. 2240, eff. 7/19/24)
