PS Business Parks Inc. of Glendale said former executive vice president and second-in-command Mary Jayne Howard filed a discrimination complaint with the California Department of Fair Employment and Housing.
PS Business Parks Chief Financial Officer Jack Corrigan said he had no other details regarding the suit.
Howard left PS Business Park eight months ago when the company sued her husband, Larry Howard, for allegedly negotiating kickbacks from the company's suppliers.
The company said Larry Howard wasn't an employee or authorized agent of PS Business Parks. He filed a cross-complaint alleging the company was interfering with his contractual relations with various suppliers.
The Howards weren't immediately available for comment.
The lawsuits are still active, Corrigan said.
PS Business owns or has a stake in 125 properties with 12.4 million square feet of space in California, Texas, Oregon, Virginia and Maryland.
