Summary
Santa Cruz County grants a density bonus of up to 35% (50% with an enhanced bonus) above the zoning maximum to unincorporated-area housing developments that set aside affordable units under SCCC Chapter 17.12. Ten percent lower-income, five percent very-low-income, or a qualifying senior project trigger the bonus, along with incentives, parking cuts and standards waivers keyed to the affordable percentage.
(A) For the purposes of this chapter, "density bonus" means a density increase over the otherwise maximum allowable residential density as of the date of application by the applicant to the County. The applicant may elect to accept a lesser percentage of density increase, including, but not limited to, no increase in density. The amount of density increase to which the applicant is entitled shall vary according to the amount by which the percentage of affordable housing units exceeds the percentage established in SCCC § 17.12.020. ... (A) For the purposes of this chapter, "enhanced density bonus" means an additional density increase provided by the County in excess of the regular 35 percent bonus provided by State law, for those developments meeting the criteria for an enhanced density bonus as set forth in this section. Any enhanced density bonus granted pursuant to this section shall be subject to a maximum resulting project density of 30 dwelling units per acre, after application of the enhanced bonus, notwithstanding the result of any enhanced density bonus calculations provided herein.

Full Breakdown
12 of the Santa Cruz County Code implements state density bonus law (Gov. Code Section 65915) for the unincorporated county. 060(A); 5 percent very-low-income yields a 20 percent bonus, rising to 11 percent for 35 percent. Senior developments receive a flat 20 percent bonus. 065(A) caps the resulting project density at 30 dwelling units per acre no matter how the calculation runs. 120. Before approval the applicant signs an affordable housing agreement recorded against the property and binding on successors, and no final inspection is issued for market-rate units until the affordable units pass inspection. 160.
Violations & Fines
The affordable housing agreement required by SCCC Section 17.12.120(D) is a legally binding deed restriction recorded against the property for at least 55 years and binding on every future owner, enforced by the Planning Director and County Counsel. Building market-rate units out of sequence breaches the ordinance: SCCC Section 17.12.120(E) bars final inspection of any market-rate unit until the required affordable units have received final inspection, and misrepresenting eligibility to obtain a density bonus can void the approval entirely.
