Summary
Chapter 17.46 grants residential developers a density bonus of up to 50 percent for providing very low or lower-income units, plus incentives, reduced parking, and waived development standards, implementing Government Code Section 65915 through a density bonus agreement approved by the planning commission.
For housing developments providing ten percent lower-income target units, the density bonus shall be calculated as follows: Percentage Low-Income Units / Percentage Density Bonus: 10/20, 11/21.5, 12/23, 13/24.5, 14/26, ... 24/50. ... For housing developments providing 100 percent of all units in the development for lower-income households ... the density bonus shall be 80 percent of the number of units for lower-income households. If a 100 percent affordable housing development is located within one-half mile of a major transit stop, the city shall not impose any maximum controls on density.

Full Breakdown
020 sets the eligibility thresholds: 10 percent lower-income units, 5 percent very low-income units, a senior citizen housing development, 10 percent moderate-income units sold to the public, 10 percent for transitional foster youth, disabled veterans, or homeless persons, 20 percent lower-income student housing units, or a 100 percent lower-income development. 040 ties the bonus to a sliding scale: at 10 percent low-income units the bonus is 20 percent, rising to 50 percent at 24 percent low-income units; at 5 percent very low-income units the bonus starts at 20 percent and also tops out at 50 percent at 15 percent very low-income units.
Senior housing developments get a flat 20 percent bonus, foster youth/veteran/homeless developments get 20 percent, student housing gets 35 percent, and a 100 percent lower-income project gets an 80 percent bonus, with no density cap at all if it sits within a half-mile of a major transit stop. 5 spaces for four or more bedrooms, and lets developers satisfy it with tandem or uncovered parking. 030(E) bars the city from applying any development standard that would physically preclude the bonus-density project, subject to specific findings on health/safety, historic resources, or conflict with state law.
070, and the city and applicant must sign a recorded density bonus agreement before entitlement. 080 lets the city charge an administrative fee, set by council resolution, to cover application review, marketing/lease-up oversight, and long-term affordability compliance monitoring.
Violations & Fines
An applicant who fails to record the required density bonus agreement before building permits are issued, or who does not maintain the affordability restriction (55 years for foster youth/veteran/homeless units, 30 years where a direct financial contribution applies under Government Code Section 65915), risks losing the density bonus and facing enforcement action to restore compliance with the recorded covenant. The city can also deny an incentive or concession only through a written finding based on substantial evidence under Section 17.46.070(C), such as a specific adverse health/safety impact or conflict with state or federal law.
