Plaza Tower


Designed by renowned architect Cesar Pelli, Plaza Tower encompasses over 470,000 square feet of Class A office space and is home to some of the most respected professional firms and corporations in the United States.

The curved facade of Plaza Tower establishes a formal entrance which relates the building to the unique facets of its surroundings. This formality is articulated by the double loggias and setbacks at the seventeenth and twenty-first floors.

Plaza Tower stands as a prominent and identifying feature in the business, cultural and social landscape of Orange County.

Property Management

The property management team is dedicated to providing outstanding customer service and maintaining the best-in-class professional office environment that has developed in our buildings over the past 30 years.


Plaza Tower has a team of on-site engineers to maintain the buildings and grounds. The outstanding quality of maintenance and constant use of new technologies over the years has allowed our buildings to achieve the Energy Star rating and LEED Gold designation.

Public Safety

An integral part of the operations is public safety, providing 24 hour monitoring by utilizing a combination of on-site officers and a centralized dispatch center. Tenants may call the Client Services line 24/7 to have a public safety officer dispatched.
