Full Breakdown
, the state Density Bonus and Other Incentives law, which requires every city to adopt an ordinance specifying how it will grant concessions and incentives to developers who build affordable housing. The chapter lays out the procedures and requirements a housing development proposal must meet and the process by which the City evaluates it and grants a density bonus or other concessions to a developer who agrees to provide targeted dwelling units. 04: the density bonus process only applies to a housing development of five or more dwelling units, not counting the density bonus units themselves.
Fractional units created by the density bonus calculation always round up to the next whole number, a rule that works in the developer's favor. Importantly, granting the density bonus is not interpreted as requiring a General Plan amendment, zone change, or other discretionary approval, meaning eligible projects get the bonus without triggering the City's normal legislative approval process. 14.
Violations & Fines
Section 9512 is a benefit and procedure ordinance rather than a prohibition, so it carries no penalty of its own; a developer who misrepresents eligibility for a density bonus or fails to record and honor the required affordability covenants on the target units can lose the bonus and face enforcement under the City's affordable housing and Development Agreement compliance provisions tied to the approved entitlement.
