The two-story building (plus partial lower level) offers flexible suite configurations across 24,940 leasable SF, with a large lobby, shared conference room, three-stop elevator, and tenant storage. A new roof, paved lot, and updated mechanical systems make this a low-deferred-maintenance acquisition.
