圣迭戈县包容性住房条例10月22日起施行：非建制地区10套以上新项目须配建可负担住房，出售项目三档为5%极低收入、10%低收入或15%中等收入
加利福尼亚州圣迭戈县—圣迭戈县《包容性住房条例》（Inclusionary Housing Ordinance）已于10月22日起施行。该条例由县监事会（Board of Supervisors）于6月24日以4票对1票通过，仅适用于县直辖的非建制地区（unincorporated areas），包括阿尔派恩（Alpine）、拉莫纳（Ramona）、莱克赛德（Lakeside）、福尔布鲁克（Fallbrook）与谷中心（Valley Center）等社区；圣迭戈、丘拉维斯塔、欧欣赛德等建制城市执行各自的住房政策，不受该条例约束。
适用门槛与配建比例方面，条例适用于10套及以上住房的新开发项目，9套及以下项目豁免，密度奖励单元与附属居住单元不计入门槛。出售型项目须三选一：5%的单元供极低收入家庭（地区收入中位数50%）、10%供低收入家庭（80%）或15%供中等收入家庭（120%）；出租型项目须三选一：5%供超低收入家庭（30%）、5%供极低收入家庭（50%）或10%供低收入家庭（80%）；涉及总体规划修正的项目要求最高，须配建20%的低收入单元。10月22日之前已向县政府提交的项目按旧规处理、不受新规约束。
替代合规方面，条例设有按优先级排列的替代路径：向县政府捐赠指定区域土地用于未来可负担住房为最高优先级，其次包括以共管公寓形式出售最多5套附属居住单元（可满足至多一半配建要求）、异地建设，以及缴纳替代费（in-lieu fees）进入县专项基金（视项目类型可满足50%或100%的要求）；开发商须先证明更高优先级的方案不可行，才能采用下一顺位方案。县政府官员在监事会审议时估计，该条例每年可产生约15至60套带产权限制的可负担住房。背景方面，按加州区域住房需求评估（RHNA），圣迭戈县须在2021至2029年间为非建制社区规划6,700套新住房，其中2,800套须供收入低于地区中位数80%的低收入与极低收入家庭。
In San Diego County, California, the county's Inclusionary Housing Ordinance took effect on October 22, 2026. The ordinance, adopted by the Board of Supervisors in a 4-1 vote on June 24, 2026, applies
The ordinance applies to new housing developments with 10 or more units; projects of nine or fewer units are exempt, and density bonus units and accessory dwelling units do not count toward the threshold. For-sale developments must choose one of three options: 5% of units at very-low income levels (50% of Area Median Income), 10% at low income levels (80% of AMI), or 15% at moderate income levels (120% of AMI). Rental developments must select from 5% of units at extremely-low income levels (30% of AMI), 5% at very-low income levels (50% of AMI), or 10% at low income levels (80% of AMI). General Plan Amendment projects face the highest requirement, 20% of units at low income levels. Any project submitted to the county before October 22, 2026, is grandfathered under the previous regulations.
The ordinance also establishes alternative compliance options in a prioritized hierarchy: donating land to the county in specified areas for future affordable housing ranks highest, followed by options including up to five on-site accessory dwelling units sold as condominiums (satisfying up to half the requirement), offsite development, and in-lieu fees paid into a dedicated county fund, which depending on project type can satisfy up to 50% or 100% of the requirement; developers must demonstrate why higher-priority options are not feasible before moving down the list. County staff told the Board of Supervisors that the ordinance could produce an estimated 15 to 60 deed-restricted affordable units per year. Under California's Regional Housing Needs Assessment process, San Diego County must plan for 6,700 new homes in unincorporated communities between 2021 and 2029, of which 2,800 must be affordable to low- and very-low-income households earning less than 80% of Area Median Income.
