STATE DENSITY BONUS LAW SAMPLE ORDINANCE

Government Code section 65915, subdivision (a)(1), states that a local government shall adopt an ordinance that specifies how compliance with State Density Bonus Law (SDBL) is implemented. This SDBL sample ordinance provides local governments with an example of the minimum requirements for an implementing ordinance that meets the requirements of state law. Additionally, since the legislature frequently amends the SDBL, the model ordinance purposely defers to state law to reduce the need for local governments to complete municipal code updates.

HCD accepts requests for technical assistance from local governments through the online Housing Accountability Unit portal at https:// calhcd.service-now.com/csp?id=sc_cat_item&sys_ id=91e19b8ac31955109a97251ce0013105.

The SDBL sample ordinance is intended to guide a local government in its adoption and implementation of a local SDBL implementation ordinance. Local governments are responsible for complying with the SDBL. HCD is not responsible for any legal matter related to or arising from a locally adopted density bonus ordinance.

Additionally, Government Code section 65915, subdivision (n), allows local governments to grant a density bonus greater than what is required by the statute when qualifying projects meet the requirements of the law. If a local government grants density bonuses that exceed what is required by the statute, the local ordinance should account for those greater density bonuses.

CHAPTER XXXX | DENSITY BONUS

SECTION XXXXXXXX – PURPOSE

This chapter implements the State Density Bonus Law, as required by California Government Code section 65915, by providing incentives and other benefits for the production of housing that is affordable to moderate, lower income, and other households in accordance with sections 65915 through 65918 of the California Government Code.

SECTION XXXXXXXX – APPLICABILITY

This chapter shall apply to any housing development, as defined in the State Density Bonus Law (Gov. Code, § 65915 et seq), that applies for and is eligible to receive a density bonus, concessions and incentives, waivers of development standards, parking reductions and all other benefits granted by the State Density Bonus Law when the applicant agrees to provide very-low, low, or moderate income housing units, or units intended to serve seniors, transitional foster youth, disabled veterans, homeless persons, or lower income students, or the proposed housing development meets other eligibility criteria in the threshold amounts specified in the State Density Bonus Law.

The brief written statement shall not include a study, feasibility analysis, or pro forma.

c. An identification of all waivers sought, including the required standard and the requested standard, and a brief written statement of why the development standard from which any waiver is sought would have the effect of physically precluding the construction of the housing development at the density and with any concessions or incentives permitted.

d. Any parking reductions requested pursuant to Government Code section 65915, subdivision (p).

e. If the housing development is proposed on any property that includes a parcel or parcels with existing dwelling units or dwelling units that have been vacated or demolished in the five-year period preceding the date of the application, an explanation of how the project meets the State Density Bonus Law’s replacement housing requirements, set forth in Government Code section 65915, subdivision (c)(3) and in particular this information:

on any property that includes a parcel or parcels with existing dwelling units or dwelling units that have been vacated or demolished in the five-year period preceding the date of the application, an explanation of how the project meets the State Density Bonus Law’s replacement housing requirements, set forth in Government Code section 65915, subdivision (c)(3) and in particular this information:

  1. A description of all dwelling units existing on the site in the five-year period preceding the date of submittal of the application and identification of any units rented in the five-year period; subject to any form of rent control through a public entity’s valid exercise of its police power; or subject to a recorded covenant, ordinance, or law restricting rents to levels affordable to households of lower or very low income.

i. If the housing development is proposed to be located on any property that includes a parcel or parcels for which no density standard using dwelling units per acre is established by the general plan, specific plan, or zoning, then the applicant may provide a base density study by estimating the maximum number of units that could be provided by a hypothetical housing development consistent with all applicable development standards prior to the award of a density bonus, incentives or concessions, waivers, or parking reductions. If the applicant provides a base density study, the city shall accept it, provided that it includes all applicable objective development standards. If the applicant does not provide a base density study, the jurisdiction shall provide a base density study. The average unit size for the hypothetical housing development shall be the same size as the average unit size for the housing development proposed. The application for a density bonus shall include a table with calculations and diagrams for the hypothetical housing development used to determine the base density.
