Orange County’s multifamily housing market is poised for a significant shift as developers prepare to deliver the largest wave of new apartment inventory in six years, ending a period of supply constraints that has helped maintain stable vacancy rates and steady rent growth in one of California’s most expensive rental markets. According to a new report from Northmarq, after delivering fewer than 800 new units in the first half of 2025—barely outpacing the anemic 700 units completed during the same period last year—the market is bracing for approximately 4,000 unit completions by year-end, representing a 43 percent increase from 2024 levels. This supply surge comes as the market demonstrates remarkable stability, with vacancy rates holding steady at 4.5 percent and asking rents reaching $2,624 per month, up 2.1 percent year-over-year.
The consistency reflects Orange County’s unique position as a supply-constrained market where vacancy rates have operated within a narrow 100 basis point range since 2015. The market’s resilience is particularly evident in its premium coastal submarkets, where rent growth has significantly outpaced the broader region. Huntington Beach and Newport Beach have posted exceptional performance, with asking rents rising 6.8 percent and 5.3 percent respectively over the past year, reaching $2,704 and $3,236 per month. These coastal communities have achieved this growth alongside vacancy improvements, underscoring the continued demand for high-end rental housing in Orange County’s most desirable locations. The performance contrasts with more moderate growth in inland areas, where Anaheim recorded a 2.4 percent annual increase to $2,396 per month.
Supporting the rental market’s stability is an improving employment landscape. After experiencing a modest contraction in the first quarter, Orange County’s job market accelerated in the second quarter, with total employment increasing 0.5 percent over the past 12 months through the addition of 8,600 positions. The private education and health services sector emerged as the clear leader, expanding payrolls by 5 percent and hiring 13,500 workers over the past year. The leisure and hospitality sector also contributed positively, adding 3,200 positions with 1.4 percent growth—a notable recovery for an industry that has faced ongoing challenges. Based on the report, employment growth is forecast to continue at a steady 0.5 percent pace in 2025, with local employers expected to add 8,500 new hires, providing a foundation for continued rental demand even as new supply enters the market.
Analysts note that the sales market has shown signs of revival after a dormant first quarter that recorded no significant transactions. Activity resumed in the second quarter with a diverse mix of properties changing hands, primarily at opposite ends of the quality spectrum. Notably, two-thirds of year-to-date sales involved Class C assets, with the majority concentrated in Santa Ana, which now accounts for two-thirds of transactions compared to just 16 percent of sales between 2020 and 2024. This shift reflects changing investor appetite and opportunities in the market’s more affordable segments. At the premium end, Class A properties achieved record pricing, with a median price of $572,300 per unit—a new high for top-tier assets in Orange County. The mix of high-end and value-add transactions has driven the overall year-to-date median sale price to $378,300 per unit, up nearly 5 percent from 2024. Cap rates have remained stable in the low-5 percent range, averaging 5.1 percent during the second quarter, consistent with levels maintained since 2023 and reflecting the market’s continued investor appeal despite broader economic uncertainties. The most notable transactions included the following:
- The Skyline at MacArthur Place, located at 15 MacArthur Place in Santa Ana, was built in 2008 and consists of 350 units—it recently sold for $239.6 million, equating to $684,571 per unit.
- In Anaheim, the 314-unit Citron Apartments at 901 E. South Street, built in 2022, sold for $144.4 million, or $460,000 per unit.
- The Coventry Court, located at 16000 Cambridge Way in Tustin, was constructed in 2012 and includes 240 units. It traded for $83 million, reflecting a price of $345,833 per unit.
- In Huntington Beach, the Huntington Breeze apartments, situated at 16171 Springdale St., date back to 1987 and comprise 114 units. The property was sold for $35 million, or $307,018 per unit.
- In Garden Grove, the Vista Del Sol Apartments, built in 1968 and located at 8911 Mays Ave., feature 52 units. This asset sold for $16.4 million, equating to $315,558 per unit.
- The Imperial Apartments at 1722 N. Bush St. in Santa Ana, built in 1985, include 51 units. They sold for $15 million, which translates to $294,118 per unit.
Northmarq analysts underline that the construction landscape reveals interesting geographic concentration, with nearly two-thirds of the 6,100 units currently under construction located in Irvine, where over 4,000 units are underway. Anaheim follows with nearly 800 units, while remaining projects are scattered across the region. Despite elevated construction activity weighing on vacancy in Irvine, the submarket has recorded the strongest absorption rates regionwide, with apartments posting net move-ins for more than 1,000 units during the past 12 months. This performance demonstrates the market’s ability to absorb significant new supply when located in high-demand areas. Multifamily permitting activity spiked dramatically in the second quarter, with developers pulling permits for more than 1,400 units—70 percent higher than the region’s average quarterly permits over the trailing five years and up from roughly 400 units in the first quarter.
The coming months will provide a crucial test of Orange County’s market fundamentals as the largest supply wave in six years hits the market. The current construction pipeline represents 2.5 percent of total inventory, slightly higher than Los Angeles County but lower than levels throughout the rest of Southern California. Vacancy rates are forecast to rise modestly to 4.7 percent by year-end, up 30 basis points annually, as new completions accelerate. However, historical patterns suggest Orange County’s vacancy rates have shown resilience during previous periods of elevated supply growth. At the same time, rent growth is expected to continue, with annual gains projected to reach 1.5 percent by year-end, bringing average rents to $2,650 per month. The Anaheim and Santa Ana areas are expected to outperform market averages, while the rapid rent growth in northern coastal submarkets may begin to moderate.
Market analysts anticipate that investment activity patterns will evolve significantly as the development cycle matures. The steady increase in project completions has coincided with a decrease in property transactions, reflecting the market’s transition through a major development phase.
“Once the development pipeline returns to historical norms, allowing room for rents and vacancies to trend more favorably, investment activity will likely return to more typical levels between mid-2026 to 2027,” the Northmarq report states.
The potential for interest rate cuts in the second half of 2025 could provide additional catalyst for deal activity, potentially reviving opportunities that previously failed to meet return thresholds. However, the immediate impact of the supply surge may continue to influence sales activity patterns through the remainder of the year.
