Nonprofit OneLegacy purchased an office building in Azusa for $18.4 million. It will be the group’s new headquarters. The nonprofit plans to relocate from downtown.

The 98,772-square-foot office building is at 1303 W. Optical Drive. OneLegacy will upgrade the lighting, glazing and HVAC systems, which will take about a year to complete.

“The new property reflects the tremendous growth OneLegacy has achieved over recent years while providing the space and resources needed for us to continue to save and heal even more lives through donation,” said OneLegacy Chief Executive Tom Mone.

OneLegacy will also build an additional 50,000-square-foot transplant recovery and research center and a 16,000-square-foot conference space. The nonprofit plans to spend $11.6 million on Phase 1 renovations and tenant improvements and $30 million on Phase 2, including donor recovery, a lab, conference space and a parking structure.

OneLegacy claims to be the largest organ, eye and tissue donation recovery group in the world. It has more than 200 hospitals and 11 transplant centers. As of February, it was the only federally designated group authorized to collect organs across the greater Los Angeles area.

In 2018, its number of donors increased 6.4% to 4,500. It brought in $105 million in 2018, which Mone previously told the Business Journal was a 10% increase from the previous year.

OneLegacy recently opened a $17 million, 40,000-square-foot transplant center in Redlands. The Azusa facility will be triple the size of the Redlands outpost.

Shadd Walker of Colliers International represented the seller, Proficiency Capital, in the building sale.

The property was built in 1987 as Aerojet’s headquarters. Northrop Grumman purchased Aerojet in 2004 and sold the building to Proficiency Capital. The building was renovated in 2019. It sits on 4.45 acres.
