Real Estate Tech Trailblazer Mark Choey Lists His San Francisco Live-Work Loft for $3.2 Million Situated in the Historic Lighthouse Lofts of SoMa, the Three-Unit Property Features Dual Kitchens, Office Space, and Exclusive Roof Deck Access

Mark Choey not only called this sleek San Francisco loft home for over a decade, but the visionary real estate tech entrepreneur also birthed a number of groundbreaking companies under its roof. Now, the founder of the indie brokerage Climb (which was acquired by Realogy subsidiary NRT in 2016) and the real estate tech platform HighNote Labs is ready to part ways with his exceptional live-work space in the historic Lighthouse Lofts, located in the heart of SoMa, listing it for $3.2 million.

The historic Lighthouse Lofts building features a striking Gothic-inspired terracotta entrance.

Originally constructed in 1924 by the Samuel H. Cowell family as the headquarters for the San Francisco Lighthouse for the Blind, this distinctive building was reimagined as a live/work community in the late 1990s and is now a Category III contributory landmark. The 22-unit structure has housed several notable residents, including artist Klari Reis and the founders of the Battery social club, Michael and Xochi Birch. Choey acquired a corner loft in the spring of 2013, combining two units for $1.4 million, before adding an adjacent unit, creating a sprawling 3,600-square-foot residence spread across two levels. The interiors, crafted by the talented Lauren Geremia of Geremia Design, combine whimsical elegance with stylish touches, including a mix of epoxy and wood floors, soaring ceilings, exposed concrete, and oversized steel-frame windows that frame stunning city views.

One of the living areas is equipped with a basketball hoop.

Units 201 and 202: The entry foyer opens into an cavernous open-concept great room.

Units 201 and 202: An adjacent dining and lounge area.

The first two lofts, units 201 and 202, encompass 2,633 square feet with three bedrooms, two baths, an enclosed office, and multiple workstations. A standout feature on the lower level is the spacious living/dining area, which flows into a kitchen outfitted with custom cabinetry, a striking ceramic backsplash, and top-tier Bosch, Bertazzoni, and Fisher-Paykel appliances, alongside a game room. A mezzanine level houses a music lounge and the primary suite. The additional 1,056-square-foot loft (unit 203) features bamboo floors and includes a combined living/dining room, kitchen, and full bath on the lower level, plus a bedroom and office on the upper floor. The property comes with three parking spaces and a private storage unit. Residents also benefit from access to a roof deck and a dedicated custodian, all for a monthly HOA fee of approximately $2,715.
