Stanford University has ended an 86-year ground lease on its campus with Alpha Omega Housing Corporation (AOHC), the alumni corporation that provides housing to the Sigma Chi fraternity.

The 550 Lasuen house is under Stanford ownership and management as of Aug. 31, after the University terminated an 86-year-old ground lease held by a group of Sigma Chi alumni.

The Sigma Chi House, located at 550 Lasuen Mall, was the only undergraduate residence overseen by a non-university entity, according to Stanford.
