San Diego County Inclusionary Housing Ordinance June 2026

June 24, 2026 • 28 min read • By San Diego Fast Cash Home Buyer

TL;DR: San Diego County Inclusionary Housing Vote (June 24, 2026)

The San Diego County Board of Supervisors votes today on an inclusionary housing ordinance requiring new developments in unincorporated areas (Fallbrook, Alpine, Ramona, etc.) to include affordable housing units. The ordinance creates a critical timing window: properties acquired before implementation avoid requirements, while future projects face compliance costs. Cash buyers can close on development sites in 7-14 days before the ordinance takes effect, securing grandfathered status.

The San Diego County Board of Supervisors is scheduled to vote today, June 24, 2026, on a Draft Inclusionary Housing Ordinance that would fundamentally reshape development economics across unincorporated areas of the county. This regulatory change affects communities including Fallbrook, Alpine, Ramona, Jamul, Spring Valley, and Lakeside—creating immediate implications for cash buyers, investors, and developers operating in these markets.

The proposed ordinance requires new market-rate housing developments to include affordable housing units when they are built, marking a significant policy shift for the unincorporated county. After the Board of Supervisors initially considered the ordinance in August 2024 but directed staff to return with revised options, today's vote represents the culmination of extensive economic analysis, stakeholder engagement, and community presentations that have generated both support and substantial resistance.

For cash buyers and real estate investors, this ordinance creates a critical timing window: properties acquired before the mandate takes effect will not be subject to the new requirements, while future development projects will face additional compliance costs and complexity that could impact project feasibility and returns.

Understanding the San Diego County Inclusionary Housing Ordinance

The San Diego County inclusionary housing ordinance is designed to address the county's obligation to ensure adequate affordable housing development within unincorporated areas in accordance with State law, the County's Sixth Cycle Housing Element, and Regional Housing Needs Allocation (RHNA) goals. The County of San Diego is responsible for planning 6,700 new homes in unincorporated communities for the 2021-2029 housing cycle, with a specific goal to finance and incentivize the creation of 2,800 Low- and Very Low-Income units.

According to the San Diego County Planning & Development Services, the ordinance applies to new housing development in the unincorporated areas of the County. While the exact percentage requirements have not been publicly finalized, county consultants have modeled set-asides ranging from 5-20 percent of project units to examine impacts on project viability across different scenarios.

The ordinance establishes a minimum project threshold that determines which developments must comply. Projects proposing fewer than the minimum number of residential units would not be required to provide affordable units, though the specific unit count triggering requirements has not been disclosed in available public documents.

Income targeting focuses primarily on Very Low-income households (up to 50% of the area median income, or AMI), which represents the greatest need category in the county's RHNA allocation. The ordinance also addresses affordability periods, though specific duration requirements have not been detailed in preliminary documents.

Developer Compliance Options

Recognizing that on-site affordable housing may not be feasible for all projects, the San Diego County inclusionary housing ordinance provides several alternative compliance pathways:

On-Site Development: Include the required percentage of affordable units within the primary project, integrating affordable housing with market-rate units.
Off-Site Development: Construct affordable housing at an alternative location within 3 miles or the vicinity of the community planning area.
Land Donation: Donate land suitable for affordable housing development to qualified affordable housing developers or the county's housing authority.
In-Lieu Fees: Pay fees deposited into a dedicated fund used to finance affordable housing projects elsewhere in the county.
ADU Credit: Accessory dwelling units may count toward inclusionary requirements under certain circumstances.
Density Bonuses: Projects that exceed affordable housing targets may receive priority permit review and density bonuses beyond state requirements.

According to best practices research, jurisdictions must ensure in-lieu fees are appropriately set to cover the true cost of constructing affordable units, calculated by determining the difference between the cost to develop the affordable unit and the total financed amount that can be covered by an affordable rent.

Geographic Impact: Unincorporated Communities Affected

The San Diego County inclusionary housing ordinance specifically targets new development in unincorporated areas—communities that fall under county jurisdiction rather than incorporated city governance. This geographic distinction is critical because it means the ordinance does not apply to the City of San Diego, which already has its own inclusionary housing requirements for projects of 10 or more dwelling units.

Key Unincorporated Communities Affected

North County Unincorporated Areas: Fallbrook, Bonsall, Rainbow, Valley Center, Hidden Meadows, and portions of San Marcos and Escondido spheres of influence.
East County Communities: Alpine, Jamul, Lakeside, Ramona, Julian, Crest, Harbison Canyon, and Pine Valley.
South County Areas: Spring Valley, Casa de Oro-Mount Helix, Bonita (unincorporated portions), and Otay.
Coastal Unincorporated Areas: Cardiff-by-the-Sea, Leucadia (portions), and Olivenhain.

These communities collectively represent significant development potential, particularly in areas like Fallbrook and Ramona where larger parcels and lower land costs have historically attracted residential developers. The median home price across San Diego County reached $922,000 in May 2026, according to Redfin market data, but unincorporated areas generally offer more affordable entry points for both developers and homebuyers. For detailed San Diego median price analysis, see our May 2026 market report.

For cash buyers, these unincorporated markets present distinct opportunities. Properties in communities like Alpine and Ramona typically offer lower acquisition costs than coastal markets while still benefiting from San Diego County's strong fundamentals: constrained inventory (approximately 2.0-2.3 months of supply countywide as of January 2026), consistent rental demand, and limited new construction pipeline.

Community Reaction and Developer Concerns

The proposed inclusionary housing ordinance has generated substantial pushback from local planning groups and development stakeholders, particularly in communities with strong rural character and slower development approval processes.

At a May 7, 2026 presentation in Ramona, the local Community Planning Group bristled at the county's affordable housing mandate proposal, with planning members raising concerns that the ordinance could extend already lengthy permit timelines and discourage development in the area.

Paul Stykel, a Ramona planning member, warned the ordinance could "add more time to an already drawn-out permit process." Basil Aruin argued that inclusionary requirements have historically functioned as development blockers, while Jonas Dyer stated he plans to oppose the ordinance, urging the county to "allow builders to build and do it quickly."

Primary Community Concerns

Loss of Local Control: Community planning groups fear the ordinance reduces their ability to shape development patterns in ways appropriate for their specific communities.
Permit Timeline Extensions: Adding affordable housing compliance requirements to an already complex approval process could extend timelines from months to years, particularly for projects requiring discretionary approvals.
Development Feasibility: Stakeholders worry that the additional costs and complexity of inclusionary requirements will make marginal projects economically unviable, reducing overall housing production rather than increasing it.

According to research on inclusionary housing impacts, a well-structured ordinance that enables developers to earn returns equivalent to or greater than what would otherwise be possible will not reduce construction activity. However, if the net cost is too great relative to land values, landowners may choose not to sell their properties, effectively preventing development.

Economic Impact on Development Feasibility

The financial implications of the San Diego County inclusionary housing ordinance are central to the policy debate and critical for cash buyers evaluating investment opportunities.

Development Cost Analysis

Inclusionary housing requirements impose real costs on developers. A housing development project is financially feasible when attainable rents or sales prices can cover total development cost, operating expenses, and a market-responsive level of developer profit. Inclusionary requirements reduce project revenues by requiring units to be sold or rented at below-market rates.

According to feasibility analysis research, the net cost of inclusionary requirements exerts downward pressure on land prices. If the net cost is small relative to land values and applied consistently across a jurisdiction, landowners will accept reduced prices. However, if the cost is too great, landowners may choose not to sell, preventing development entirely.

Example: 100-Unit Project with 10% Set-Aside

Market-rate unit value: $600,000
Affordable unit value (Very Low-income): $250,000
Revenue reduction per affordable unit: $350,000
Total revenue reduction (10 units): $3,500,000

Developer Response Strategies

Developers typically respond to inclusionary costs in three ways:

Reduce land acquisition prices by the net present value of the inclusionary cost
Utilize density bonuses and incentives to add market-rate units that offset affordable unit costs
Choose alternative compliance options (in-lieu fees, off-site development) if more cost-effective

Impact on Property Values

The ordinance's impact on existing property values is nuanced. Research indicates that affordable housing does not typically negatively impact nearby home values, and well-designed, well-maintained affordable housing generally does not affect neighboring property values.

Differentiated Value Impacts

Development Sites: Properties with development potential may experience value pressure as developers factor inclusionary costs into land acquisition budgets.
Existing Homes: Completed homes in unincorporated areas are unlikely to see value impacts from the ordinance itself, as the requirement only applies to new construction projects above the minimum threshold.
Pre-Ordinance Development: Properties with projects already entitled or under construction before the ordinance's effective date will be grandfathered, potentially creating a value premium for "vested" projects not subject to new requirements.

Cash Buyer Opportunities

For cash buyers and investors, the inclusionary housing ordinance creates specific strategic opportunities:

Pre-Implementation Acquisition Window: Properties acquired before the ordinance takes effect can be developed under current regulations, avoiding inclusionary requirements. This creates timing value for cash buyers who can close quickly on development sites.
Distressed Development Sites: Developers unable or unwilling to navigate inclusionary requirements may sell entitled or partially developed projects at discounts, creating opportunities for sophisticated cash buyers with affordable housing development experience.
Land Banking: Cash buyers can acquire developable parcels in unincorporated areas before inclusionary costs are fully priced into land values, holding for future development or resale as market conditions evolve.
Alternative Compliance Arbitrage: Investors who can efficiently deliver affordable housing (through modular construction, streamlined processes, or partnerships with affordable housing developers) may find opportunities to acquire projects from conventional developers seeking to avoid direct affordable housing production.

According to San Diego cash buyer market analysis, cash buyers can close on San Diego investment properties in 7-14 days, significantly faster than financed transactions that typically require 30-45 days. This speed advantage is particularly valuable in the current environment where developers may be seeking to close transactions before the ordinance takes effect.

Comparison to City of San Diego Requirements

Understanding the difference between the county's proposed ordinance and the City of San Diego's existing inclusionary housing requirements provides important context for investors operating across multiple jurisdictions.

The City of San Diego Inclusionary Affordable Housing Ordinance has been in effect for years and applies to all new residential development of 10 or more dwelling units outside the Coastal Overlay Zone, five or more dwelling units within the Coastal Overlay Zone, and all condominium conversions of two or more dwelling units.

Aspect	City of San Diego	County (Proposed)
Minimum Project Size	10 units (5 in Coastal Zone)	Not yet disclosed
Set-Aside Percentage	10% for rental, 10% for ownership	Under consideration (5-20% range modeled)
Income Targeting	60% AMI (rental), 120% AMI (ownership)	Focus on Very Low (50% AMI)
Affordability Period	55 years (rental), 45 years (ownership)	Not yet disclosed
In-Lieu Fees	$210,000-$275,000 per unit	Not yet disclosed
Geographic Scope	Within city limits	Unincorporated county areas

For cash buyers operating across both city and county markets, these differences create distinct investment considerations. City projects face known inclusionary requirements with established compliance costs, while county projects currently face regulatory uncertainty that will be resolved by today's Board vote.

Strategic Implications for Cash Buyers and Investors

The San Diego County inclusionary housing ordinance creates both challenges and opportunities for cash buyers and real estate investors operating in unincorporated markets.

Short-Term Opportunities (Pre-Implementation)

The period between today's Board vote and the ordinance's effective date represents a critical window for cash buyers:

Development Site Acquisition: Properties with development potential in unincorporated areas may be available at current pricing before inclusionary costs are fully incorporated into land values. Sellers motivated to close before implementation may accept competitive offers from cash buyers who can close quickly.
Entitled Project Purchases: Developers who secured entitlements under previous regulations but lack capital or appetite for construction may sell projects at discounts. Cash buyers can acquire these "grandfathered" projects and develop without inclusionary requirements.
Partnership Opportunities: Traditional developers uncomfortable with affordable housing production may seek joint venture partners or buyers who can navigate inclusionary compliance. Cash buyers with affordable housing experience or relationships with affordable housing developers can structure creative acquisitions.

Long-Term Strategic Positioning

Beyond the immediate implementation window, the ordinance reshapes long-term investment strategies:

Smaller Project Focus: If the ordinance sets a minimum threshold (e.g., 10 units), projects below that threshold will not face inclusionary requirements. Cash buyers can target smaller infill sites, lot splits, or small-scale developments that remain exempt.
Alternative Compliance Mastery: Investors who understand in-lieu fee economics, off-site development opportunities, and density bonus strategies will have competitive advantages. Properties where density bonuses can offset inclusionary costs become more valuable.
Affordable Housing Specialization: The ordinance increases demand for affordable housing development expertise. Cash buyers who partner with or become qualified affordable housing developers can pursue both inclusionary projects and stand-alone affordable developments funded by in-lieu fees and county housing programs.
Geographic Arbitrage: Some unincorporated areas may offer more favorable development economics than others based on land costs, entitlement complexity, and market rents/prices. Cash buyers can target communities where inclusionary requirements have minimal impact on feasibility.

Risk Mitigation Strategies

Conduct Feasibility Analysis: Before acquiring development sites, model projects with inclusionary requirements at various set-aside percentages (5%, 10%, 15%, 20%) to understand sensitivity to different Board decisions.
Secure Entitlements Quickly: If acquiring sites before implementation, accelerate entitlement processes to secure vested rights under current regulations before the ordinance takes effect.
Build Affordable Housing Relationships: Establish relationships with qualified affordable housing developers, nonprofit housing organizations, and agencies that can facilitate alternative compliance strategies.
Monitor Implementation Details: The Board's vote today will establish the framework, but implementation regulations, fee schedules, and administrative procedures will be developed over subsequent months. Active monitoring ensures investors can adapt strategies as details emerge.

Timeline and Implementation Process

The San Diego County inclusionary housing ordinance follows a multi-phase implementation timeline:

August 28, 2024: Board of Supervisors initially considered the ordinance but directed staff to conduct additional economic analysis and return with revised options ensuring housing production is not negatively impacted.
May 2026: County staff conducted community presentations, including the May 7 session in Ramona where local planning groups expressed concerns about permit timelines and development feasibility.
June 24, 2026 (Today): Board of Supervisors scheduled to vote on ordinance adoption. If approved, the ordinance framework, set-aside percentages, income targeting, affordability periods, and alternative compliance options will be established.
Post-Adoption Period: Following Board approval, county staff will develop implementation regulations including in-lieu fee schedules, off-site development standards, land donation procedures, density bonus guidelines, and affordability deed restriction templates.
Effective Date: The ordinance will specify an effective date, likely 30-90 days after adoption, during which projects can be submitted under current regulations.
Grandfathering Provisions: Projects with complete applications submitted before the effective date, or projects with vested entitlements, will likely be grandfathered under previous regulations.

For cash buyers, understanding this timeline is critical for strategic decision-making. Projects acquired and entitled during the post-adoption/pre-effective period may avoid inclusionary requirements, while projects in earlier acquisition or planning stages will need to incorporate compliance costs.

Regional Housing Context and RHNA Goals

The inclusionary housing ordinance must be understood within the broader context of California's housing crisis and regional planning requirements.

San Diego County faces an ambitious Regional Housing Needs Allocation (RHNA) for the 2021-2029 housing cycle. The County of San Diego is responsible for planning 6,700 new homes in unincorporated communities, with a goal to finance and incentivize the creation of 2,800 Low- and Very Low-Income units.

County Housing Initiatives

Innovative Housing Trust Fund: More than $100 million invested to help finance 3,000 affordable homes regionwide.
County-Owned Land Program: 11 County properties being converted into affordable housing to create 1,700 homes for approximately 3,800 residents.
ADU Separate Sale Ordinance: Recently approved ordinance allowing ADUs to be sold separately as condominiums under AB 1033, creating additional affordable homeownership opportunities.
Streamlined Approvals: Process improvements to accelerate housing development approvals in unincorporated areas.

The inclusionary housing ordinance represents an additional tool to generate affordable units through private development rather than relying solely on public funding and county-owned land. This context suggests the ordinance is one piece of a multi-faceted strategy, not a silver bullet solution. Cash buyers should recognize that county housing policy will continue evolving with additional incentives, streamlining measures, and programs designed to achieve RHNA targets.

Frequently Asked Questions

When does the San Diego County inclusionary housing ordinance take effect?

The Board of Supervisors is voting on the ordinance today, June 24, 2026. If approved, the ordinance will likely take effect 30-90 days after adoption, though the specific effective date will be included in the adopted ordinance text. Projects with complete applications submitted before the effective date may be grandfathered under previous regulations.

Which communities are affected by the inclusionary housing ordinance?

The ordinance applies exclusively to unincorporated areas of San Diego County—communities under county jurisdiction rather than incorporated city governance. This includes Fallbrook, Alpine, Ramona, Jamul, Spring Valley, Lakeside, Valley Center, Bonsall, Rainbow, Julian, Cardiff-by-the-Sea, Leucadia (portions), Olivenhain, and other unincorporated communities. The ordinance does not apply to the City of San Diego or other incorporated cities.

What percentage of affordable housing will developers be required to provide?

The exact set-aside percentage has not been publicly disclosed in preliminary documents. County consultants modeled scenarios ranging from 5-20 percent of project units to assess feasibility impacts. The Board of Supervisors will establish the final percentage as part of today's vote. For comparison, the City of San Diego requires 10% of units to be affordable.

Can developers pay fees instead of building affordable units?

Yes, the ordinance includes in-lieu fee provisions as an alternative compliance option. Developers can pay fees deposited into a dedicated fund used to finance affordable housing projects elsewhere in the county. The specific fee amounts will be established in implementation regulations following Board adoption, calculated to cover the true cost of constructing affordable units.

Will the ordinance apply to small residential projects?

The ordinance establishes a minimum project threshold below which inclusionary requirements do not apply. The specific unit count triggering requirements has not been disclosed, but the City of San Diego's threshold of 10 units (5 in Coastal Zone) may provide guidance. Small-scale developments, single-family homes, and lot splits that fall below the threshold would be exempt.

How will this affect property values in unincorporated areas?

Research indicates that well-designed affordable housing does not typically impact nearby property values negatively. However, the ordinance may create differentiated impacts: development sites may experience downward pressure on land values as developers factor inclusionary costs into acquisition budgets, while existing completed homes are unlikely to see value impacts from the ordinance itself.

What are density bonuses and how do they help developers?

Density bonuses allow developers to build more units than normally permitted under zoning in exchange for including affordable housing. California's state density bonus law already provides these incentives for projects with five or more units. The county ordinance may provide additional density bonuses beyond state requirements for projects exceeding minimum affordable housing targets.

Can developers build affordable units off-site instead of within the main project?

Yes, off-site development is an approved alternative compliance option. The ordinance specifies that off-site affordable housing should be located within a radius of 3 miles or the vicinity of the community planning area, ensuring affordable units remain connected to the communities generating the requirement.

How does this ordinance differ from the City of San Diego's inclusionary housing requirements?

The key differences are geographic scope and some policy details. The City of San Diego ordinance applies within city limits and requires 10% of units in projects of 10+ units to be affordable, with 55-year affordability periods for rentals. The county ordinance applies to unincorporated areas and is being adopted today, with set-aside percentages and affordability periods to be finalized in the Board vote.

What opportunities does this create for cash buyers?

Cash buyers have several strategic opportunities including pre-implementation acquisition of development sites before inclusionary costs are fully priced into land values, purchase of entitled projects from developers seeking to exit before ordinance takes effect, and focus on smaller projects below minimum thresholds that remain exempt. Cash buyers' ability to close in 7-14 days provides competitive advantages during the implementation transition period.

Conclusion: Positioning for the Post-Ordinance Market

The San Diego County Board of Supervisors vote today on the inclusionary housing ordinance marks a pivotal moment for real estate investment in unincorporated communities across the county. Whether the ordinance is adopted as proposed, modified based on stakeholder feedback, or delayed for further analysis, the trajectory is clear: affordable housing requirements will become a permanent feature of the development landscape in unincorporated San Diego County.

For cash buyers and investors, success in this evolving environment requires three strategic responses:

Act Decisively in the Pre-Implementation Window: Properties acquired before the ordinance takes effect, or projects entitled under current regulations, will avoid inclusionary requirements. Cash buyers who can move quickly have a competitive advantage during this transition period.
Develop Inclusionary Housing Competency: Long-term success requires understanding alternative compliance options, density bonus strategies, and affordable housing development economics. Investors who master these tools will identify opportunities that conventional developers overlook.
Maintain Strategic Flexibility: The ordinance framework will be established today, but implementation details will evolve over months and years. Successful investors will monitor regulatory developments, adapt strategies as details emerge, and position portfolios to benefit from both market-rate and affordable housing opportunities.

The median home price across San Diego County reached $922,000 in May 2026, while housing inventory remains constrained at 2.0-2.3 months of supply. These fundamental market conditions—strong demand, limited supply, and constrained new construction—will persist regardless of inclusionary housing requirements. The investors who thrive will be those who view the ordinance not as an obstacle but as a factor that can be understood, modeled, and incorporated into sophisticated investment strategies.

Unincorporated San Diego County communities from Fallbrook to Alpine to Ramona will continue offering compelling opportunities for cash buyers who understand local market dynamics, development economics, and the regulatory environment shaping the future of housing production.
