GLENDALE, California — PS Business Parks, Inc. (AMEX:PSB) announced that it has completed three separate real estate transactions aggregating approximately 361,000 square feet for a combined purchase price of $56.4 million.

The buildings are adjacent to a 197,000 square foot complex that the Company acquired and developed between 1999 and 2001.
