**Former Gritstone Biomanufacturing Facility in Pleasanton Sells for $8.5 Million**
JLL Capital Markets has arranged the $8.5 million sale of Tri-Valley GMP, a 42,620-square-foot cGMP industrial biomanufacturing facility located at 4696 Willow Road in Pleasanton, California. The transaction was led by Erik Hanson, Senior Director at JLL, who represented the seller. The buyers are Cannae Partners and REALM.
Previously serving as Gritstone bio’s Tri-Valley hub, the facility was vacated in February. The property has undergone significant enhancements to support advanced biotech operations. According to JLL, the building now features 12 production rooms, ISO 5+ cleanroom space, and fully equipped quality assurance and quality control laboratories, making it a state-of-the-art lab and manufacturing complex.
Strategically located in the Tri-Valley and 680 Corridor region, the property offers excellent access to major transportation routes, including Interstates 680 and 580, as well as nearby Bay Area Rapid Transit (BART) stations. Pleasanton is considered a high-demand market for research and development, especially in the flex and lab space sector, with nearly 300,000 square feet absorbed over the last two years.
This sale highlights the continued demand for top-tier life sciences and biomanufacturing facilities in key Northern California submarkets.
