Irvine, CA Zoning Overlays & Bonuses: Density Bonus Law (2026)

Sec. 2-3-10.A states the purpose directly: "to comply with State density bonus standards, which are intended to provide incentives for the production of housing for Very Low income, Low, and Moderate income households, or senior households in accordance with California Government Code §§ 65915, 65918." Subsection B commits the City to grant density bonus and incentive requests under that same state statute rather than a separate local formula. Subsection C requires target (affordable) units to be built concurrently with market-rate units unless the applicant and City agree to an alternate schedule in the density bonus housing agreement, and requires target units to be dispersed on-site with a bedroom mix matching the market-rate units, or a higher bedroom count.

Beyond the base state bonus, Irvine layers two local land-donation incentives. Under Sec. 2-3-10.G, an applicant who donates land to the City (or a City-designated nonprofit) for affordable housing gets a density increase "equal to one-half of the base density... of the donated land," on top of any Government Code § 65915(b) bonus, up to a combined 50 percent increase; the donated parcel must be at least half an acre or large enough for 20 units. Under Sec. 2-3-10.H, donating resources worth at least as much as the in-lieu fee otherwise owed earns up to a 35 percent base-density increase instead of the land-donation bonus. Every density bonus requires a recorded density bonus housing agreement (Sec. 2-3-10.F) binding on future owners, with use restrictions running at least 55 years and final approval or disapproval made by the Planning Commission.
