San Diego Density Bonus: 70% of Affordable Housing 2024

Understanding San Diego's Density Bonus Programs: How They Work

Unlike traditional community plan updates that require years of public hearings and political negotiations, density bonus programs operate on a different principle: they offer developers immediate incentives in exchange for including affordable housing in their projects. This "carrot" approach has proven far more effective than the "stick" of mandatory inclusionary housing requirements.

Here's how the system works: Developers building five or more dwelling units in the City of San Diego may be eligible for an increase in development density in exchange for setting aside a percentage of units as affordable housing. The percentage of affordable units provided correlates to a specific density bonus and up to five incentives that can include reductions in setback requirements, parking requirements, or open space standards.

San Diego enhanced California's base density bonus law in 2016 under Mayor Kevin Faulconer's administration. While state law caps density bonuses at 11% affordable units, San Diego raised this to 15%, with corresponding increases in development incentives and building capacity. This local enhancement proved so successful that in 2020, Governor Gavin Newsom signed AB 2345 to expand the program statewide—characterized at the time as "the most impactful housing production law" of that year.

The results speak for themselves: applications for density bonus projects increased by 900% after San Diego enhanced its program, with applications for deed-restricted affordable units seeing a 473% increase. In 2020, 44% of all homes entitled in San Diego used the program, a number that has only grown in subsequent years.

The Complete Communities Program: Density Bonuses on Steroids

If San Diego's enhanced density bonus was effective, the Complete Communities Housing Solutions (CCHS) program, adopted in 2024, took the concept even further. This optional program allows dramatically more dense housing projects near high-frequency transit, creating what critics call "unlimited FAR" (floor area ratio) development opportunities in some areas.

Under Complete Communities, qualifying projects earn heightened FAR by restricting 40% of base units for rental at affordable rates—specifically 15% for very low income households, 10% for low income households, and 15% for households earning up to 120% of area median income. In exchange, developers receive FAR ratios of 4.0, 6.5, 8.0, or even unlimited FAR in certain zones, along with up to five development incentives and various fee waivers.

The program offers substantial financial benefits to developers, including waiver of Development Impact Fees (DIF) for all covenant-restricted affordable units, all units under 500 square feet, and certain three-bedroom units if the development's residential density exceeds 120% of maximum permitted density. Perhaps most importantly, compliance with Complete Communities itself doesn't require discretionary approval for most projects, meaning massive infill developments can proceed without triggering California Environmental Quality Act (CEQA) review.

For neighborhoods within Transit Priority Areas—recently expanded to Sustainable Development Areas covering properties within a one-mile walk to major transit stops—this means an additional 5,000 acres of developable land became eligible for these intensive development programs. Virtually all of Normal Heights, North Park, and University Heights fall within these zones, as do significant portions of El Cerrito and City Heights.

El Cerrito and Adams Avenue: A Case Study in Development Pressure

No project better illustrates the dramatic impact of density bonus programs than the multi-story, multi-unit ADU development on Adams Avenue in El Cerrito that became a flashpoint in San Diego's housing debate throughout 2025.

This project, completed in January 2025, placed a seven-unit, two-story ADU structure behind a single-family home—capable of housing at least 16 people according to neighbors. One resident described how his "backyard garden paradise has been tainted" by the development, with windows from the new structure overlooking his private space. The project became a rallying point for critics who argued that San Diego's ADU bonus program—widely believed to be the most aggressive in California—had been "exploited" by developers and was "damaging community character in neighborhoods across San Diego."

The controversy led the City Council to unanimously direct city planners to bring forward legislation to reform or potentially eliminate the ADU bonus incentive in an unexpected shift from the city's previously pro-housing stance. The Planning Commission voted unanimously to recommend a two-story cap for all new backyard apartments and directed officials to explore additional options to reduce the programs' neighborhood impacts.

For homeowners on Adams Avenue and throughout El Cerrito, this project demonstrated how quickly neighborhoods can change under density bonus rules. El Cerrito's median home price sat at $652,495 in March 2025, up 20.9% from the previous year—but homeowners near intensive development projects faced a different reality: construction noise, loss of privacy, parking challenges, and uncertainty about how multi-unit projects would affect long-term property values and quality of life.

While adding ADUs can potentially increase property values for those building them, especially if they offer desirable features and rental income potential, the impact on neighboring properties tells a different story. Homeowners living adjacent to multi-story ADU developments report concerns about privacy loss, noise from tenants, and changes to neighborhood character that may negatively affect their property's desirability to future buyers.

City Heights: Where Density Bonuses Meet Affordable Housing Demand

While El Cerrito's Adams Avenue controversy grabbed headlines, City Heights has become a laboratory for how density bonus programs function in already-dense, working-class neighborhoods with significant affordable housing needs.

City Heights home prices were up 11.4% year-over-year in November 2025, selling for a median price of $670,000—well below San Diego County's overall median of approximately $1 million but representing significant appreciation for this historically affordable neighborhood. The neighborhood has been a consistent recipient of the city's Bridge to Home affordable housing funding, alongside communities like El Cerrito, Downtown, Encanto, Hillcrest, and Clairemont.

The neighborhood's location within a Transit Priority Area and its underlying zoning make it prime territory for Complete Communities projects. About 95% of projects using San Diego's affordable housing density bonus programs are located within half a mile of high-performing transit stops, and about two-thirds are in high-opportunity census tracts—categories that describe much of City Heights.

For City Heights homeowners, the density bonus surge creates a complex dynamic. On one hand, new affordable housing construction like the Bridge to Home program addresses genuine community needs and can bring neighborhood improvements. On the other hand, the construction process itself—which can last years for larger projects—brings noise, traffic disruption, parking challenges, and visual blight from construction equipment and materials. Homeowners adjacent to planned density bonus projects often face a difficult decision: wait out years of construction in hopes property values continue appreciating, or sell quickly to a cash buyer before intensive development begins and market perception shifts.

Community Plans vs. Density Bonuses: Understanding the Critical Difference

One of the most important things homeowners need to understand is that density bonus programs operate entirely separately from community plan updates—and they're delivering far more housing.

Community plans establish base zoning and maximum allowable densities for neighborhoods through a political process involving community input and City Council approval. These updates can take years or even decades to complete, with extensive environmental review and public debate. The recent Clairemont and College Area community plan updates, for example, went through years of hearings before approval.

Density bonus programs bypass this entire process. They allow development that exceeds what community plan base zoning would otherwise permit—and they do so as a matter of right, with minimal discretionary review. As one analysis noted, "San Diego has several bonus programs that bypass the political gridlock and allow more homes than restrictive community plans."

The numbers tell the story: in 2024, San Diego permitted 8,782 homes and more than half used bonus programs, with 71% of building permits in bonus density programs that don't count toward the City's community plan upzoning—including ADUs, Complete Communities, and City and State Affordable Density Bonus Programs. These programs create additional housing beyond the upzoning the City has planned through traditional channels.

What this means for homeowners is critical: your neighborhood's community plan may show one level of allowable density, but density bonus programs enable developers to build significantly more. A property zoned for 20 dwelling units per acre under the community plan might support 50, 75, or even more units when a developer uses Complete Communities or state density bonus provisions.

This disconnect explains why many homeowners feel blindsided by development in their neighborhoods. They attend community plan meetings, review zoning maps, and believe they understand what's allowed—only to see projects approved that seem to violate everything they thought they knew about local zoning. The reality is that density bonus programs have become the primary mechanism for housing production in San Diego, eclipsing traditional community planning processes.

Development Pressure and Property Values: What Homeowners Need to Know

Living in a density bonus-eligible neighborhood creates unique pressures that traditional zoning doesn't account for. Homeowners face uncertainty about when, where, and how intensive development might occur on neighboring properties—uncertainty that can affect both quality of life and long-term property values.

Construction impacts from density bonus projects can be substantial and prolonged. Multi-story developments require extended construction timelines, often 18-36 months for larger projects. During this period, adjacent homeowners endure noise from heavy equipment, traffic from construction vehicles, dust from demolition and grading, parking challenges when construction crews take street spaces, visual blight from equipment and materials storage, and potential damage to their properties from vibration or errant construction activities.

Property value impacts vary significantly based on proximity to development. Properties immediately adjacent to multi-story density bonus projects often see negative impacts from loss of privacy, reduced natural light if new structures create shadows, noise from tenants in multi-unit developments, and parking spillover if new developments have minimal parking requirements. Meanwhile, properties further from development sites may actually benefit from neighborhood improvements, new amenities that development brings, and general upward price pressure from limited housing supply.

San Diego's overall housing market has shown resilience, with the average home taking 35 days to sell—significantly faster than the 63-day national average. However, individual neighborhood performance varies dramatically. Coastal areas like La Jolla and Del Mar maintain the strongest performance with 4-7% appreciation, while areas undergoing intensive redevelopment may see more volatility.

For homeowners in Normal Heights, University Heights, El Cerrito, and City Heights—neighborhoods where density bonus development is most concentrated—the question becomes whether to stay and weather the transformation, or sell before major construction begins. Those who choose to sell often prefer cash buyers who can close quickly, typically within 7-14 days, allowing them to exit before construction impacts affect their daily lives and property marketability.

When to Consider Selling: Timing the Market in Density Bonus Neighborhoods

For homeowners in density bonus-eligible areas, timing a sale can make a significant difference in outcome. Several factors suggest optimal timing for considering a cash sale:

Cash buyers offer particular advantages in these situations. Traditional sales in San Diego average 80 days from listing to close (45 days on market plus 35 days to close), while cash buyers can close in as little as 7 days. This speed matters when construction timelines loom or when you want to avoid the stress of showing your home while adjacent properties undergo disruptive development.

The trade-off, of course, is price. Cash buyers typically offer around 70% of estimated after-repair value, meaning you'll receive less than market value in exchange for speed, certainty, and convenience. For many homeowners facing years of construction disruption, reduced privacy, and uncertainty about long-term property values, this trade-off makes sense—particularly in neighborhoods like El Cerrito and City Heights where density bonus development is rapidly accelerating.

The Future of Density Bonus Development in San Diego

Despite the backlash that led to reforms of the ADU bonus program, density bonuses overall continue to dominate San Diego's housing production strategy. The December 2025 analysis showing 70% of affordable units coming through bonus programs demonstrates their central role in meeting state housing mandates—and there's no indication this will change.

If anything, density bonus programs are expanding. The 2023 expansion from Transit Priority Areas to Sustainable Development Areas added 4,612 developable acres eligible for bonus ADU programs and other high-density policies. The Complete Communities program, adopted in 2024, offers even more generous incentives than previous programs. And the city's aggressive permitting pace—8,782 new homes in 2024 alone—suggests density bonus development will only accelerate.

For neighborhoods like Normal Heights, University Heights, El Cerrito, City Heights, Clairemont, and others within Sustainable Development Areas, this means continued development pressure. Properties that seem safely situated in single-family neighborhoods today may find themselves adjacent to four-, six-, or eight-story mixed-use developments within a few years as property owners and developers take advantage of density bonus incentives.

The political landscape also favors continued density bonus expansion. While community groups have successfully advocated for reforms to the most controversial ADU bonus provisions, the broader density bonus framework enjoys strong support from housing advocates, city leadership, and state government. Mayor Gloria's administration has made housing production a central priority, and California's housing mandates create ongoing pressure to approve projects that include affordable units.

Homeowners who value neighborhood stability, single-family character, and predictable development patterns increasingly find themselves at odds with city and state housing policies that prioritize density and affordability over existing residents' preferences. For those unwilling or unable to adapt to rapid neighborhood transformation, selling to a cash buyer offers a path to exit on their own terms before development fundamentally changes their community.

Conclusion

San Diego's density bonus programs have fundamentally reshaped how housing gets built in the city. With 70% of affordable units from 2021-2024 coming through these incentive programs, and more than half of all 2024 permits using density bonuses, these programs now drive housing production far more than traditional community planning processes.

For homeowners in El Cerrito, City Heights, Normal Heights, University Heights, and other neighborhoods within Sustainable Development Areas, this shift creates both opportunities and challenges. New development can bring neighborhood improvements and rising property values—but it also brings construction disruption, privacy loss, parking challenges, and uncertainty about long-term community character.

The Adams Avenue controversy in El Cerrito demonstrated how quickly neighborhoods can change under aggressive density bonus policies. While reforms may limit the most extreme ADU developments, the broader trend toward density bonus-driven development continues unabated, supported by city leadership and state housing mandates.

Homeowners facing nearby density bonus projects have choices to make: stay and weather years of construction and neighborhood transformation, or sell to a cash buyer and exit quickly before development impacts property values and quality of life. For many, particularly those who value privacy, quiet, and single-family neighborhood character, selling before construction begins offers the best path forward.

If you own property in a San Diego neighborhood seeing density bonus development pressure—whether it's a single-family home adjacent to a planned multi-story project or a property in an area where multiple developments are clustering—understanding your options and timing your decision strategically can make a significant difference in outcome. In a city where density bonus programs now define housing production, being informed about how these policies affect your property has never been more important.
