IRVINE, Calif.

Irvine Company’s portfolio was nearly 90% leased at year-end, significantly outperforming the national office market vacancy rate of 22.2%, according to JLL’s Q4 2025 U.S. Office Market Dynamics.
This leasing momentum reflects Irvine Company’s continued focus on delivering the highest-quality workplaces through ongoing investment in premium amenities, experiences and market-ready solutions. As companies refine their workstyles, Irvine Company’s portfolio scale and versatility appeal to a wide range of customers—from small businesses seeking premium, move-in-ready space to specialized R&D and industrial users requiring highly customized environments.
Irvine Company also demonstrated strong customer retention in 2025. Renewals accounted for more than five million square feet—which is more than half of all leasing activity—and underscores the value customers place on long-term landlord relationships and best-in-class service.
“In 2025, the office market continued to see demand for amenity-rich, well-located workplaces that offer an elevated experience, bring teams together and drive growth and productivity. We’re seeing significant leasing momentum from technology, professional services, life sciences and healthcare customers, along with continued strength in lease renewals—reinforcing that companies are prioritizing quality, stability and long-term value in their workplace decisions.”
– Roger DeWames, President of Irvine Company Office Properties.

“We’ve been committed to the innovation economy in San Diego for nearly 20 years, growing alongside the investors and entrepreneurs we serve. Working with Irvine Company, we continue to expand our footprint here, offering our people and clients a space that inspires creativity and collaboration.”

“Silicon Valley Center’s amenities will enhance our employee well-being initiatives in a LEED Gold and Energy Star-certified space that’s closely aligned with our commitment to the environment. Together, we’re creating a greener world for our employees, customers and communities.”
“Irvine Company has consistently set the standard for investing in elevated, amenity-rich workplaces that perform in today’s market. Relocating our Chicago office to 300 North LaSalle reflects our confidence in the strength of Irvine Company’s portfolio and our shared focus on delivering high-quality environments that attract leading businesses.”
