Fullerton's Development Story Starts With a Lawsuit
Most cities in Orange County are adding housing because the state told them to. Fullerton is adding housing because the state told them to, then sued them when they did not move fast enough, and then signed a legal settlement that set hard deadlines for compliance. The Governor's office, the California Attorney General, and the Department of Housing and Community Development were all involved. It is the kind of regulatory pressure that does not leave much room for debate at the local level.
The result is one of the most dramatic rezoning programs in Orange County history. The city's Housing Incentive Overlay Zone applies to 759 parcels across 593 acres of currently non-residential land. Developers who build on those parcels with 20 percent affordable housing get by-right approval, bypassing years of discretionary review. The total development capacity unlocked by the overlay exceeds 35,000 units, far more than the 13,209 the state requires.
Meanwhile, the city's most significant long-term development opportunity sits on 35 acres directly adjacent to Orange County's busiest train station: the Fullerton Transportation Center Specific Plan, a transit-oriented vision for 1,560 homes, a hotel, offices, and retail built around a Metrolink and Amtrak hub that serves 3,000 passengers daily.
Downtown Fullerton already has one of the most vibrant urban cores in North Orange County. A historic commercial district, a live music scene, proximity to Cal State Fullerton, and now billions in planned housing investment on and around the transit corridor. Here is how it all fits together.
The Mandate: 13,209 Units and a 600 Percent Increase
Every California city receives a Regional Housing Needs Assessment allocation each planning cycle. For the 2021 to 2029 cycle, Fullerton's allocation is 13,209 units. To understand how significant that number is, the previous cycle's requirement for Fullerton was 1,841 units. The 2021-2029 mandate is more than 600 percent higher than what came before it.
Of the 13,209 required units, 5,187 must be deed-restricted for low or very low income households, which is the category that the private market is least likely to produce without subsidy or regulatory incentive. The remaining units are spread across moderate and above-moderate income categories where market-rate development is more feasible.
When Fullerton inventoried its existing capacity, the shortfall was nearly the full 13,209. The city simply did not have enough residentially zoned land to accommodate the mandate through existing zoning alone. The entire city needed to be rethought as a place where housing could be built on parcels that had never previously allowed it. That is what the Housing Incentive Overlay Zone is designed to accomplish, and it is why the program applies to parcels across the city, not just in the traditional residential zones.
How the State Forced Fullerton's Hand
California has been systematically using legal enforcement to push cities that resist housing growth into compliance. Fullerton became one of the higher-profile cases. The city failed to adopt a state-compliant Housing Element within the required timeline, which triggered an enforcement action by the California Department of Housing and Community Development.
In January 2024, California Attorney General Rob Bonta, Governor Gavin Newsom, and state housing officials announced a formal settlement with the City of Fullerton. The terms were specific and legally binding:
- Adopt a compliant Housing Element no later than November 5, 2024
- Modernize the city's zoning code to accommodate new housing by December 29, 2024
- Comply with the Affirmatively Furthering Fair Housing statute, which requires the city to actively work against patterns of segregation in its housing planning
The City Council adopted the Housing Element on January 7, 2025, slightly past the settlement deadline but close enough to satisfy the state's core requirements. The HIOZ zoning program followed as the implementation mechanism, converting the policy commitments of the Housing Element into legally enforceable zoning changes on the ground.
The settlement is not unusual in the current California housing enforcement environment. What is unusual is the scale of Fullerton's required response. The combination of 759 rezoned parcels, by-right approval pathways, and the transit-oriented development opportunity at the Transportation Center makes Fullerton one of the more consequential housing battlegrounds in Orange County for the remainder of this decade.
The HIOZ: 759 Parcels, By-Right Approval, and What It Means for Developers
The Housing Incentive Overlay Zone is the legal mechanism that makes Fullerton's housing mandate executable. Applied to 759 currently non-residential parcels across 593 acres of the city, the HIOZ allows developers to build multifamily housing on land that previously could not accommodate it, under a streamlined by-right process that eliminates the lengthy discretionary approval hearings that can delay California projects by years.
The deal for developers is straightforward: include a minimum of 20 percent deed-restricted affordable units in your project and you qualify for by-right approval. No lengthy environmental review, no discretionary hearing, no opportunity for neighborhood opposition to kill the project through the approval process. The city processes the application administratively if the project meets the overlay zone's design and affordability criteria.
The total theoretical buildout capacity of the 759 HIOZ parcels exceeds 35,000 units, far more than the 13,209 the state requires. That headroom is intentional: California's housing law requires cities to demonstrate capacity at 125 percent of their RHNA allocation to account for projects that do not move forward. The realistic number of units that will actually be built on HIOZ parcels through 2029 will depend heavily on interest rates, construction costs, and market conditions, but the legal and zoning pathway is now open in a way it has never been before in Fullerton.
Local critics have noted that the HIOZ, if fully built out, could theoretically nearly double Fullerton's population. That is not a near-term projection, but it signals how transformative the underlying zoning change is relative to what Fullerton has historically looked like as a city.
The Fullerton Transportation Center: The Transit-Oriented Anchor
The most significant long-term development opportunity in Fullerton sits on 35 acres immediately adjacent to the Fullerton Transportation Center, Orange County's busiest Metrolink station. The FTC serves approximately 3,000 passengers daily on Metrolink commuter rail lines connecting Fullerton to Los Angeles, Riverside, and San Bernardino, as well as Amtrak's Pacific Surfliner, which runs daily between San Diego and San Luis Obispo with stops throughout the Los Angeles basin and Orange County.
The City of Fullerton selected JMI Realty and the Morgan Group as the Master Planner for the FTC site and commissioned architect Johnson Fain to develop the Fullerton Transportation Center Specific Plan, a form-based code framework that envisions:
- 1,560 multifamily residential units
- 100,000 square feet of retail
- 100,000 square feet of office space
- 120,000 square feet of hotel development
- A new parking structure
- Parks and pedestrian-oriented public space
- Preservation of the site's historic buildings
The Specific Plan uses a form-based code rather than traditional use-based zoning. The distinction matters: a form-based code regulates what buildings look like and how they relate to streets and public space, rather than simply separating uses into permitted and prohibited categories. The approach is specifically suited to dense, walkable, transit-oriented districts where the quality of the pedestrian environment matters as much as what goes inside any individual building.
The FTC development is a long-term vision rather than an immediate construction project. JMI Realty was acquired in February 2025, which introduces some uncertainty about the project's near-term momentum. What is certain is that the planning framework exists, the site is identified, the city is committed, and 3,000 daily train passengers already provide the built-in ridership that makes transit-oriented development at this scale viable. When capital markets favor the project, the legal and planning infrastructure is ready.
California's SB 79, which took effect in 2026, further strengthens the case for FTC-area development by upzoning parcels near high-frequency transit statewide. Land within walking distance of Fullerton's train station now has enhanced by-right development rights under state law, independent of any city action.
What Is Being Built Now
Fullerton's development pipeline is broader than any single landmark project. The city reports more than 1,100 units currently approved or under construction across the city as of early 2026, with several projects in plan check and environmental review adding to the queue.
Among the active projects:
- Pointe Commons at 1600 W. Commonwealth: A 62-unit affordable housing development. An information meeting was held with the community in November 2025, with the project advancing through the city's review process.
- 770 South Harbor: Completed apartments near downtown Fullerton offering 1 to 3 bedroom floor plans in a contemporary mixed-use format, contributing to the growing residential population along Harbor Boulevard.
- Multiple HIOZ pipeline projects: Several projects are in plan check and staff review taking advantage of the newly established by-right approval pathway. These projects represent the first wave of development under the HIOZ program and will determine the pace at which the overlay zone's capacity translates to actual housing.
The pipeline also includes projects stalled due to financing constraints. Higher interest rates through 2024 and 2025 reduced the number of multifamily projects that could pencil out even with favorable zoning, and Fullerton mirrors the broader Orange County trend of approved projects sitting in a holding pattern waiting for capital markets to improve. As rates continue to ease, the approved pipeline represents near-term supply that can move quickly.
Harbor Boulevard Gets a Road Diet: Infrastructure Following the Density
One of the clearest signals that a city is serious about its density ambitions is investment in the pedestrian and cycling infrastructure needed to support more residents living close together. Fullerton is making that investment on Harbor Boulevard, the main corridor connecting downtown to the wider city.
In April 2025, Fullerton secured a $4.85 million grant from OCTA and SCAG for the Harbor Boulevard Complete Streets Improvement Project. The project reduces Harbor Boulevard from six lanes to four between Brea Boulevard and Valencia Mesa Drive, converting the freed-up space into buffered bicycle lanes and improved sidewalks. Construction is scheduled to begin in summer 2026.
The design philosophy behind this kind of project, often called a road diet, reflects a straightforward calculation: a six-lane arterial optimized for car throughput is not compatible with the kind of walkable, active street life that makes dense residential development attractive to the residents being asked to live without the suburban lot sizes they might have elsewhere. Narrowing the roadway slows traffic, makes crossing easier on foot, and creates the conditions where ground-floor retail can succeed and where residents feel comfortable walking to the train station, the coffee shop, or the park rather than driving to each.
For the Fullerton Transportation Center area specifically, a more pedestrian-friendly Harbor Boulevard corridor makes the case for transit-oriented development even stronger. If residents can comfortably walk from an FTC apartment to the platform, buy a coffee on the way, and board a train to Los Angeles without needing a car, the value proposition of living near the station increases and so does the market for the housing that the Specific Plan envisions.
Cal State Fullerton and the Built-In Demand Base
Any discussion of Fullerton's housing market has to account for Cal State Fullerton, one of the largest universities in California with more than 40,000 students and a significant faculty and staff population. CSUF sits less than two miles from downtown and generates consistent, year-round demand for rental housing in a way that most Orange County cities simply do not have.
Student housing demand is particularly valuable for infill development economics because it is not cyclically sensitive in the same way that traditional homebuyer demand is. Students need to live somewhere near campus regardless of interest rates. That baseline demand provides a floor under rental occupancy rates for Fullerton's growing apartment inventory and helps justify new construction in periods when market-rate demand from working professionals might be softer.
The combination of university-driven demand, transit access to Los Angeles employment, and the HIOZ's by-right approval pathway creates a compelling case for Fullerton as a multifamily investment market over the next decade. For buyers considering the area, a growing renter population drives demand for ownership housing as well. As the density increases around downtown and the FTC corridor, the neighborhood becomes more urban and more walkable, which historically translates to sustained appreciation for owners who purchased before the transformation is complete.
