Located directly across from Alta Plaza Park in Pacific Heights, 2690 Jackson Street offers a rare opportunity to acquire a pride-of-ownership building with flexible potential uses. Spanning approx. 4,600 sq. ft. (per tax records), the three-story property plus penthouse was most recently occupied by a private school and offers excellent repositioning potential. The building features large classroom-style spaces with high ceilings, abundant natural light, and classic architectural details, including crown moldings, built-ins, and a dramatic top-floor lounge with fireplace, exposed beams, and views toward the Bay and Alcatraz. Configured for single-tenant use, it includes a 2-car garage, elevator, and fire sprinkler system. Built in 1922, it retains much of its original character with a concrete slab foundation, wood post-and-beam framing, copper plumbing, 400-amp electrical, flat built-up roof, and central gas-fired radiant heat. Delivered fully vacant, it's ideal for an owner-user, school, non-profit, or residential conversion. Positioned at Jackson and Scott Streets, the property is surrounded by top schools, luxury homes, and parks, with easy access to Sacramento Street retail, the Presidio, and major transit.
