Market Fundamentals: Vacancy, Rent Trends & Demand Dynamics

Orange County’s apartment occupancy rates remain among the highest in the nation. As of the third quarter of 2025, the market’s overall vacancy rate stands at approximately 4.1%, a level that has stayed essentially flat over the past year. This is one of the lowest vacancy rates among major U.S. markets, ranking second-lowest out of the 50 largest metro areas. By comparison, the national multifamily vacancy rate has expanded to around 8%, highlighting Orange County’s unusually tight supply-demand balance. In practical terms, Orange County landlords are operating at 95–96% occupancy, which has been the norm for the past decade. Such high occupancy reflects a chronic housing shortage: affordable housing remains in extremely high demand, and even the newer luxury complexes are finding tenants as the region adds jobs and households.

Absorption (net leasing demand) has been consistently positive, albeit restrained by limited new supply. Over the 12 months through Q3 2025, Orange County absorbed roughly 2,500 apartment units, up from the prior year and a clear sign of ongoing renter demand. However, this pace still lags the historical annual absorption average of about 2,900 units. In fact, absorption in 2024 totaled only ~2,200 units (slightly higher than 2023’s level), largely because there were fewer new apartments available to lease than in past expansion periods. Demand has been bolstered by job growth, rising incomes, and a rebound in international immigration, which together have kept many would-be homebuyers in the rental market. With limited inventory to absorb, any new deliveries are quickly filled – a dynamic that has kept vacancy near 4% and underscores Orange County’s supply constraints.

Rent trends have been relatively flat in the past year, but are expected to reaccelerate. After a nation-leading rent surge in 2021–2022, Orange County saw rent growth stall out at roughly 0% in 2024, as property owners prioritized occupancy retention during a period of economic uncertainty. As of mid-2025, average asking rents are up only 1.4% year-over-year, reflecting this breather in rent increases. Many operators chose to offer renewals without large increases (and even applied concessions in new leases) in order to maintain near-full buildings. Those who aggressively pushed rents often saw higher vacancies, so the prevailing strategy has been to keep tenants in place. Class A luxury buildings, in particular, experienced a slight rent correction in 2024 – annual rent growth for 4 & 5 Star apartments swung from +4.6% at the end of 2023 to a year-over-year decline of about 1% in 2024 as a wave of new high-end supply hit the market. By contrast, rents in lower-tier, affordable units have been more stable: even during the slowdown, 1 & 2 Star (workforce) apartments still notched roughly +2% rent growth annually. Overall, Orange County rents remain among the priciest in the nation, but an interesting shift has occurred – local income growth has outpaced rent growth recently, slightly improving affordability. The average apartment now commands less than 28% of the median household income, down from a record 30%+ rent-to-income burden seen in mid-2022. With incomes still rising (~4% in the past year) and occupancy so tight, analysts expect landlords will regain pricing power. If job and population growth continue, rent increases in 2025 could return to the 3–4% range, closer to Orange County’s historical average rent growth of 4%+ per year. In sum, the market’s fundamentals – low vacancies, steady absorption, and limited new supply – position Orange County for a renewed period of healthy rent gains once economic conditions stabilize.

Financial Analysis: Cap Rates, Sales Volume & Investor Sentiment

Despite higher interest rates cooling real estate activity nationally, Orange County’s multifamily investment market has demonstrated resilience. Transaction volume did slow in 2023–2024, but not as dramatically as in many other regions. In 2023, Orange County’s apartment sales volume was about 30% below its recent 5-year average, a milder drop than the 56% plunge seen in U.S. sales overall during the capital markets tightening. Deal flow even picked up modestly in 2024: approximately 150 apartment transactions closed in Orange County in 2024 (about a 20% increase in deal count from the 2023 trough), though dollar volume only ticked up slightly to roughly $1.4 billion. This total is still well below peak years, reflecting the bid-ask spread created by higher financing costs. Nevertheless, investor interest in Orange County remains strong – buyers are drawn to the market’s robust demand, low vacancy, and limited future supply risk. These fundamentals, combined with the presence of many wealthy local investors, mean that property values have held up better than expected. Prices did correct from their frothy 2021 highs, but there has been no fire sale; on the contrary, cap rates in Orange County are still among the lowest in the nation because investors are willing to pay a premium for stable Southern California assets.

Cap rate trends: Over the past 18–24 months, rising interest rates pushed Orange County multifamily cap rates upward from the unprecedented sub-3% levels seen in 2021 to the mid-4% to low-5% range by late 2024. For institutional-quality properties, prevailing cap rates have settled roughly in the 5% range (±50 bps), based on recent trades. For example, one 160-unit garden complex in Santa Ana (built 1969, 94% occupied) sold in August 2024 for ~$41 million, reflecting a 5.3% cap rate – a notable increase from valuations a couple of years prior. Similar mid-5% cap rates have been observed in other 100+ unit sales in secondary submarkets. However, Orange County’s unique investor profile (dominated by long-term private holders and 1031 exchange buyers) has kept cap rates lower on smaller deals, especially in prime coastal locations. Some private buyers are accepting initial yields in the 3–4% range for well-located assets, essentially “parking” capital in Orange County for the long run and betting on future rent growth. One illustrative sale was a 5-unit property in Seal Beach that traded in August 2024 at roughly $525,000/unit – a 3.2% cap rate – as a 1031 exchange buyer was willing to forgo yield for a trophy coastal asset. These low-yield acquisitions underscore investors’ confidence in Orange County’s long-term appreciation and rent trajectory. Indeed, by early 2025 there were signs that the worst of the cap-rate expansion had passed; nationwide, cap rates for top-tier multifamily assets began compressing again after Q1 2024, suggesting that values may have bottomed out. In Orange County, industry sources foresee a similar stabilization: asset values inched up in late 2024 and are forecast to rise further in 2025 as cap rates level off and rent growth returns toward its historical norm. This nascent optimism is contributing to improved investor sentiment.

Investor sentiment and volume: While many institutional investors (including several Los Angeles-based REITs and private equity players) paused acquisitions in 2023, sentiment is gradually improving in 2025. The combination of a strong rental outlook and a perceived peak in interest rates is luring some capital off the sidelines. Orange County’s investment appeal is its reputation as a “safe haven” market – characterized by affluent demographics, high housing demand, and extremely constrained supply growth. Acquisition yields remain low by national standards (a reflection of those strengths) and local owners are often well-capitalized, which has prevented distress sales. By Q2 2025, brokers reported increased bidding activity, especially for well-located mid-size properties and value-add deals. Sales volume in early 2025 was still relatively soft, but there is an expectation that deal velocity will accelerate in the latter half of 2025 as price expectations between buyers and sellers converge. Notably, the overall price per unit in Orange County (averaging around $380,000 over the past 12 months) remains higher than most markets, and only slightly off its peak. Investors are effectively pricing in the market’s resiliency. InnoWave Studio’s sources indicate that many private buyers – including family offices and exchange-motivated investors – are pursuing Orange County multifamily assets for long-term holds or value-add repositioning plays, rather than short-term flips. Meanwhile, institutional buyers are selectively acquiring newer properties in submarkets with limited upcoming competition (for instance, newer assets in built-out coastal cities). Overall, the investment climate in Orange County for 2025 can be described as cautiously optimistic: buyers and lenders remain disciplined due to higher debt costs, but the enduring strength of market fundamentals (low vacancies, high incomes, and durable rent growth) is expected to support transaction activity going forward. As the broader capital markets recover and certainty improves, Orange County’s multifamily sector is positioned to attract increased investor interest, aligning with broader real estate finance trends in the region.

Development & Architectural Trends: Luxury vs. Workforce Housing and Redevelopment

New development in Orange County’s multifamily sector remains heavily skewed toward luxury projects, even as the need for workforce housing grows. Nearly all recent and ongoing apartment constructions are high-end, Class A communities aimed at upper-income renters, mainly because soaring construction costs and land prices push developers to seek higher rents to achieve feasible returns. Meanwhile, demand at the lower end of the market continues to intensify – occupancy rates for older, more affordable buildings are the highest in the market, often effectively 97%+ full. As of Q3 2025, vacancy in 1 & 2 Star (workforce) apartments is only ~3.3%, the lowest among all quality tiers. By contrast, the newest 4 & 5 Star properties have around 5–5.5% vacancy on average, partly due to recent lease-ups. This dichotomy highlights a structural issue: demand for affordable rentals is overwhelming, yet new supply is almost entirely luxury-focused. Developers target the upscale segment to offset high development costs (land, labor, materials) and to attract institutional investors, but the consequence is a persistent shortage of workforce housing. In Orange County’s tight-knit communities, this often translates to older Class B/C apartments commanding bidding wars among renters, while Class A landlords compete on concessions. The lack of new mid-tier housing has drawn concern from civic leaders, though efforts like incentive zoning and public-private partnerships for affordable units are only slowly gaining traction. For now, Orange County’s development pipeline is dominated by luxury multifamily, with extensive amenities (pools, co-working lounges, high-end finishes) designed to justify premium rents.

A noteworthy architectural trend addressing Orange County’s land scarcity is the redevelopment of obsolete retail and commercial sites into apartments. The county’s development landscape is increasingly shaped by urban redevelopment opportunities that convert malls, shopping centers, and office parks into mixed-use housing communities. For example, The Irvine Company’s “Colonnade at the Marketplace” project – a redevelopment of a portion of the Irvine Marketplace shopping center – and Simon Property Group’s plan to replace the Sears at Brea Mall with apartments are marquee instances of this trend. In fact, proposals are currently on the table to deliver over 12,000 new housing units by repurposing parts of a dozen different mall properties across Orange County. This indicates that a significant share of the county’s future multifamily growth will “sprout from shopping malls,” turning underutilized parking lots and retail pads into housing. These mixed-use projects typically incorporate pedestrian plazas, dining, and other community amenities, blending luxury housing with lifestyle centers. They are seen as a win-win: developers unlock high-value infill land (often with supportive zoning changes from cities eager to revitalize aging commercial zones), and municipalities make progress toward state-mandated housing goals without carving into untouched land. Another emerging angle is the redevelopment of office campuses to residential use, especially in the Irvine Spectrum and South Coast Metro areas, as remote work leaves some office parks under-occupied. In summary, adaptive reuse and infill redevelopment have become key strategies to overcome Orange County’s space constraints – the region is essentially building new luxury housing on the bones of old retail to meet housing demand.

Geographically, Irvine stands out as the dominant location for new development within Orange County. Long the county’s jobs hub and a master-planned city with available land, Irvine accounts for roughly two-thirds of all apartments currently under construction in the market. Over 4,000 units are underway in Irvine alone – including large projects like the Spectrum Terrace residential expansions and the aforementioned Marketplace redevelopment – out of about 5,900 units under construction countywide. This concentration in Irvine is no accident: Irvine’s pro-growth policies, extensive remaining tracts controlled by major developers (the Irvine Company, FivePoint, etc.), and strong economic base (tech and university jobs) make it the epicenter of multifamily building. Elsewhere in Orange County, new development is comparatively sparse. Land constraints and community resistance have kept the pipeline thin in built-out cities like Huntington Beach, Costa Mesa, or Anaheim (aside from a few specific large projects). Even where land is available, entitling a multifamily project can be challenging – for instance, a planned 500-unit complex in Anaheim Hills was rejected by the city in late 2024 due to resident opposition over density and wildfire evacuation concerns. According to InnoWave Studio’s sources, as of mid-2025 Orange County has roughly 5,900 units (13 projects) under construction, equal to only ~2.3% of existing inventory, which is below the national average development ratio. By comparison, in some fast-growing Sunbelt markets, 6–12% of the existing apartment stock is under construction at any given time. Orange County’s low development rate underscores the supply constraints imposed by its fully urbanized landscape and stringent approval processes. A few pockets beyond Irvine are seeing activity – Santa Ana and Anaheim had some larger complexes open in 2024, and cities like Cypress and Laguna Niguel saw rare multifamily additions – but these are the exceptions. For most Orange County communities, “built out” is the status quo, and new housing tends to come only by replacing something else. In effect, the geographic distribution of new projects tilts heavily to South County (Irvine and its surroundings), while Central and North County grow mainly through small infill and redevelopment. This pattern carries implications for investors: submarkets outside Irvine have very limited new supply risk on the horizon, whereas Irvine itself faces a moderate risk of temporary oversupply in the next few years. Even so, given Irvine’s continued job and population growth, analysts expect that new deliveries there will be absorbed “in stride,” without significantly elevating the metro’s vacancy beyond the ~4% equilibrium.

Economic Context: Employment, Migration & Affordability

Broader economic trends in Orange County provide important context for the multifamily market’s performance. The local economy in 2025 is solid but not without challenges. Job growth has been ongoing – Orange County recovered strongly in 2021 and continued to add jobs through 2024 – yet the rate of growth has lagged the national average since 2022. One reason is a tight labor supply: the county’s unemployment rate fell back below 4% in 2023 and remains around the mid-3% range, indicating labor market saturation. Essentially, Orange County is near full employment, and a shortage of available workers has somewhat capped the pace of job expansion. Total nonfarm employment in mid-2025 is roughly equal to the pre-pandemic peak, whereas nationally employment is ~6% above pre-pandemic levels (and the neighboring Inland Empire is ~7% above). This suggests that while Orange County’s economy is robust, it hasn’t grown as fast as some lower-cost regions that attracted more residents post-2020. Nonetheless, the quality and diversity of Orange County’s job base remain high. The county is a hub for professional and business services, technology and life sciences, tourism, and higher education, among other sectors. Major employers are expanding: for example, Walt Disney Co. (the county’s largest employer) received Anaheim’s approval in 2024 for a multi-year expansion plan (“DisneylandForward”) projected to create over 4,000 construction jobs and 2,300 permanent jobs in the coming years. Another pillar, the University of California, Irvine (UCI), employs 25,000+ people and anchors a thriving tech and biotech cluster in the Irvine area. Companies like Edwards Lifesciences and Blizzard Entertainment continue to grow their footprint in the region, attracting skilled workers. These economic drivers fuel housing demand: as high-paying jobs draw professionals into Orange County, many opt to rent (at least initially) due to the high cost of homeownership and the desire for flexibility/proximity to work. Additionally, the county’s amenities and quality of life – from climate and beaches to top-ranked schools and low crime rates – make it a magnet for renters who might be able to live elsewhere but choose Orange County.

Population and migration: Orange County’s population growth has been modest in recent years. The metro population is approximately 3.17 million in 2025, growing at only about 0.3% per year recently. High housing costs have led to periods of net domestic out-migration (local residents moving to more affordable regions), particularly during the 2017–2022 period when many Southern Californians left for the Inland Empire, Arizona, Texas, and beyond. However, these outflows appear to be moderating as of 2024–2025. Out-migration has slowed in part because the pandemic-era rush to remote-work destinations has abated, and more workers are returning to offices in Orange County or finding that the grass isn’t greener elsewhere. At the same time, international immigration is rebounding, which is significant for Orange County given its large foreign-born population. New immigrants (as well as returning foreign students/workers) contribute substantially to rental housing demand. The county also continues to see household growth (~0.5% annually) despite slow population gains, indicating smaller household sizes and new household formation (e.g., young adults moving out on their own). Demographically, Orange County is aging somewhat – the median age and share of retirees are creeping up – but it remains a family-friendly area that attracts middle-aged professionals with children. Affordability remains the primary long-term concern: with median single-family home prices around $1 million, many middle-income families are priced out of ownership, keeping them in the renter pool longer. The median household income in Orange County is roughly $117,000 (one of the highest in the U.S.), and it has been rising ~4% annually. This income growth has provided a bit of a safety valve for housing costs. As noted earlier, the typical rent now consumes around 27–28% of median income, improved from about 30% a few years ago. Still, Orange County is the 5th most expensive major rental market in the country, and affordability challenges persist for lower-income residents. Rent burden disparities are evident: higher-earning renters in luxury buildings might spend only 20% of income on rent, whereas those in workforce housing can easily spend 40%+. Local governments and developers are increasingly exploring solutions such as affordable housing mandates and density bonuses to address the gap. From an economic perspective, relatively high incomes and low unemployment bode well for rent collections and rent growth potential (tenants can absorb moderate increases). However, if affordability erodes too far, it could eventually constrain the region’s ability to attract new talent or force more residents to migrate out. For now, Orange County benefits from being a high-income, high-demand coastal economy – one that supports a robust multifamily market, even if growth rates are less heady than those of cheaper Sunbelt locales.

Strategic Outlook: Investment Opportunities and Development Risks

Given the market conditions described, Orange County offers a blend of attractive investment opportunities and important risks/challenges that stakeholders should weigh as part of their 2025 strategy. Below is a summary of key opportunities and risks in the Orange County multifamily sector:

• Opportunities – Redevelopment and Infill Projects: One of the most promising avenues is investing in or partnering on redevelopment projects that convert underutilized commercial land into housing. The trend of urban redevelopment in California is strong in Orange County – with numerous mall-to-apartment plans and other mixed-use conversions in the pipeline. These projects can unlock significant value, as they often turn well-located but obsolete properties (e.g. portions of shopping centers, office parks) into modern multifamily communities. Developers who navigate the entitlement process successfully can create high-demand housing where new supply is otherwise nearly impossible to add. From an investor’s perspective, backing such projects – or acquiring newly delivered assets born from redevelopment – offers a chance to capitalize on Orange County’s supply constraints and pent-up demand. Cities are increasingly supportive of these adaptive-reuse developments as a way to meet housing needs, which improves the probability of execution. In short, redevelopment of retail/office sites into apartments represents a major growth opportunity in the coming years.

• Opportunities – Value-Add and Workforce Housing Investments: Another strategic play is focusing on value-add acquisitions in the workforce housing segment (older 3 Star and 1–2 Star properties). With vacancy in these properties extremely low and virtually no new competing supply on the horizon, existing affordable complexes have a captive renter base. Savvy investors can purchase 1970s–1980s vintage apartment communities and undertake moderate renovations (unit upgrades, adding amenities) to boost rents, knowing that demand will remain robust. Even without large upgrades, better management and marketing can improve NOI in under-managed assets. Many private buyers are pursuing this strategy – in fact, 1031 exchange buyers have been willing to accept low initial cap rates (3–4%) for well-located Orange County apartments, confident that long-term rent growth and property appreciation will deliver strong returns. The continued shortage of affordable rentals means occupancy risk in this segment is minimal, and landlords often have waiting lists. Investing in workforce housing also positions investors to benefit from any future government incentives for preserving or creating affordable units. Overall, buying and repositioning Class B/C assets in Orange County is an opportunity to generate yield in a high-barrier market – essentially “buying low” on the quality spectrum but leveraging high demand.

• Opportunities – High-Growth Submarkets and Niche Segments: Orange County’s varied submarkets present targeted opportunities. Irvine, for instance, with its concentration of jobs and high-end development, will continue to attract affluent renters – owning stabilized Class A properties in this submarket can be lucrative as Irvine’s economy expands. On the other end, investing in built-out coastal cities (Newport Beach, Huntington Beach, etc.) offers stability, as these areas have little room for new development and command premium rents. Additionally, niche segments like senior housing or student housing tied to local universities (UCI, Chapman) have potential, given demographic trends and limited existing stock. Investors might also look at transit-oriented developments (TODs) around train stations or major transit corridors; with Southern California focusing on improved transit, properties with convenient commutes could see rising demand. It’s worth noting that Orange County historically averaged ~4% rent growth annually and rarely saw overall rents decline, even in recessions. The market’s long-term track record of rent resilience – supported by high-income tenants and diversifying employment – underpins the opportunity for steady growth. In essence, submarkets with strong job and population prospects, and properties in supply-constrained locations, position investors to capture outsized rent gains and value appreciation as the region’s prosperity endures.

• Risks – Interest Rates and Financing Costs: The most immediate risk to Orange County multifamily investment is the macro-economic climate of higher interest rates and tighter credit. Financing costs are significantly above their 2021 lows, which reduces investor leverage and can thin out the pool of buyers. As noted, 2024’s sales volume was subdued partly because many investors could not finance deals at pricing that sellers wanted. If interest rates remain elevated or rise further, cap rates could face upward pressure again, potentially softening property values. While Orange County has been resilient, it is not immune to capital market cycles – a surge in borrowing costs or a recessionary credit crunch could momentarily stall the investment market. Investors should be cautious with highly leveraged strategies and ensure deals pencil out with conservative debt assumptions. Likewise, developers must grapple with higher construction loan rates, which could delay or cancel projects (as evidenced by no major new construction starts since mid-2024). The upside is that if inflation and rates stabilize or fall, Orange County cap rates may compress further given the weight of capital eager to invest in top-tier markets. Nonetheless, the cost of capital is a critical risk factor to monitor in 2025.

• Risks – Localized Oversupply in Irvine and Lease-Up Challenges: Although Orange County’s supply growth is modest overall, the pipeline is highly concentrated in a few areas – notably Irvine. This presents a localized oversupply risk. With over 4,000 units under construction in Irvine, all slated to hit the market within a couple of years, there could be periods of elevated vacancy and rent concessions in that submarket. Indeed, rent growth in Irvine’s luxury segment already turned negative last year amid a batch of new deliveries. While demand in Irvine is strong (fueled by job growth and migration to the area) and is expected to absorb the new units over time without issue, investors owning properties there should be prepared for competitive leasing conditions in the short term. New luxury projects often offer significant concessions (one to two months free rent) during initial lease-up, which can put pressure on nearby properties to match incentives. There is also the risk that if the economic cycle weakens, Irvine could temporarily see its vacancy rise above the normal 4% level given the volume of new apartments. This risk is mitigated by the fact that developers have slowed down on starting any further projects – effectively, the pipeline after the current wave is very thin – but it remains a factor to watch. Outside of Irvine, oversupply risk is low (most cities won’t see enough new units to tip the balance). Asset management in Irvine over the next 12–24 months will require deft marketing and possibly flexibility on rents to maintain occupancy in the face of new competition.

• Risks – Regulatory and Approval Challenges: Orange County’s regulatory environment can pose challenges for development and operations alike. On the development side, stringent zoning laws, lengthy approval processes, and community opposition (“Not In My Backyard” sentiment) can significantly delay or derail projects. Even when there is strong demand for housing, city councils and local residents often push back on density and height, as seen with the Anaheim Hills project rejection. This adds uncertainty and cost for developers (entitlement risk), and it means the pipeline can be hard to replenish quickly. For investors, a slow entitlement process is a double-edged sword: it limits new competition (a positive for owners of existing assets) but it also makes expanding portfolios via development or major rehab more complex. On the operational side, California’s regulatory landscape includes statewide rent control (e.g. AB 1482 capping annual rent increases on most units) and ever-evolving tenant protection laws. Strict eviction rules and rent cap regulations could limit landlords’ ability to raise rents aggressively or reposition properties swiftly. While Orange County doesn’t have additional local rent control beyond state law, the political climate in California favors renter protections, so investors need to underwrite with those constraints in mind. Additionally, any future policy changes (such as stricter inclusionary housing requirements or higher affordable unit set-asides for new developments) could impact project feasibility. In summary, navigating the regulatory framework is a key risk – successful investors will need strong local expertise, legal guidance, and often a community outreach strategy to mitigate this.

• Risks – Affordability and Demand Sustainability: Finally, there are broader economic and social risks. Orange County’s high cost of living, if not addressed, could eventually impede its growth by driving more families and young professionals away. While recent data shows out-migration easing, the county must maintain a balance where job opportunities and quality of life outweigh housing costs for newcomers. Affordability pressures also raise the specter of political responses (as mentioned, more aggressive rent control or development fees) which could alter the investment calculus. Moreover, Orange County is not immune to macro-economic downturns: a recession that impacts its key industries (tourism, tech/medtech, etc.) or a significant spike in unemployment would soften rental demand and could lead to higher vacancies or slower rent growth. Investors should scenario-plan for a possible economic cooling. However, it’s worth noting that in past downturns (e.g. 2008 and 2020), Orange County’s rental market proved relatively resilient – any dips in rents or occupancy were smaller and shorter-lived than national averages, thanks to the region’s desirability and constrained supply. Still, caution is warranted: maintaining conservative projections and adequate reserves is prudent in case the economic environment shifts.

  
  

Outlook: Balancing these factors, Orange County’s multifamily market in 2025 appears fundamentally strong with a positive outlook, provided investors remain mindful of the risks. The strategic opportunities – infill development, value-add rehabs, and investing in high-demand submarkets – offer paths to create value and capitalize on the market’s strengths (high incomes, low vacancies, limited new supply). The risks, chiefly from economic conditions and regulatory hurdles, can be managed with due diligence and a long-term perspective. For developers, focusing on projects with broad community support (or by-right zoning) and staying attuned to cost control will be key. For investors, Orange County represents a classic “high-demand, low-supply” market, where patience and quality tend to be rewarded. As 2025 unfolds, expect Southern California housing trends to continue emphasizing housing affordability solutions, adaptive reuse development, and the interplay of migration patterns – all of which will shape Orange County’s multifamily performance. InnoWave Studio’s analysis indicates that Orange County will remain one of the most sought-after multifamily markets in California, offering both stability and growth potential for those who navigate its nuances effectively.
