Santa Cruz County, CA Zoning Overlays & Bonuses: Density Bonus Law (2026)

Chapter 17.12 of the Santa Cruz County Code implements state density bonus law (Gov. Code Section 65915) for the unincorporated county. A housing development qualifies by providing 10 percent of units for lower-income households, 5 percent for very-low-income households, 10 percent for moderate-income buyers in a common-interest development, or by building senior housing, and earns a bonus that scales with the affordable percentage: 10 percent low-income yields a 20 percent bonus, rising to 20 percent low-income for a 35 percent bonus under SCCC Section 17.12.060(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. Projects that clear 21 percent low-income or 12 percent very-low-income units qualify for an enhanced bonus reaching 50 percent, though SCCC Section 17.12.065(A) caps the resulting project density at 30 dwelling units per acre no matter how the calculation runs. Applicants may also request incentives or concessions (one for 10 percent low-income, two for 20 percent, three for 30 percent), reduced parking under SCCC Section 17.12.090 (one space for studios and one-bedroom units, two for two-to-three bedrooms, two and one-half for four or more bedrooms), or waivers of development standards that would physically preclude the bonus project, all reviewed under SCCC Section 17.12.120.

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. In the Coastal Zone, density bonus approvals stay subject to Coastal Act Section 30604(f) and remain appealable to the California Coastal Commission; nothing in Chapter 17.12 supersedes the Coastal Act, per SCCC Section 17.12.160.
