685 Market Street

Description

Jones Lang LaSalle Americas, Inc. (“JLL”), as exclusive advisor, is pleased to present the rare opportunity to acquire the fee simple interest in 685 Market Street (the “Property” or “685 Market” or the “Monadnock Building”), a 210,244 square foot historic office building along Downtown San Francisco’s most prominent thoroughfare with high visibility ground floor retail. Currently 75% leased, 685 Market is home to the long-term headquarters of Notion - one of the fastest growing AI companies in the world.


Originally constructed in 1907, the Monadnock Building stands as one of San Francisco’s most iconic office properties with a storied history dating to the Great San Francisco Earthquake. While retaining its historic character, the building has undergone comprehensive renovation by current ownership, creating a fully modernized landmark asset.


The Property currently serves as the global headquarters of Notion, a pioneer in the rapidly expanding AI industry and one of the world’s fastest growing AI companies. Notion’s dynamic growth has already driven two expansions within the building, with contractual options to expand into the rest of the building.


685 Market presents investors with a compelling opportunity to acquire a fully renovated landmark office building on Market Street, secured by a high-growth technology tenant with substantial lease term and expansion potential.
