1253-1257 Mason Street presents a rare opportunity to acquire a completely vacant three-unit building in a prime Nob Hill location. The property is comprised of two three-bedroom flats and one two-bedroom flat, each occupying a full floor and offering spacious layouts with generously sized rooms. Delivered 100% vacant, the building offers tremendous flexibility for an owner-occupier, TIC developer, or investor seeking a value-add opportunity. The property enjoys stunning panoramic views spanning Coit Tower, the Transamerica Pyramid, Bay Bridge, Downtown skyline and the Bay. Period architectural details, bay windows and large-scale floor plans provide an attractive foundation for renovation, with the opportunity to create three distinctive residences that take full advantage of the building's size, character and views. A substantial garage provides parking for approximately two to three cars, along with additional space that may offer potential for expansion or other improvements, subject to City approval. With its complete vacancy, exceptional views, generous unit sizes, large garage and multiple potential exit strategies, the property represents a compelling opportunity to create significant value. Ideally situated in Nob Hill near the borders of Chinatown and North Beach, the property offers convenient access to some of San Francisco's most vibrant dining, shopping and cultural destinations. Jackson Square, Washington Square, North Beach, Chinatown and the Financial District are all within easy reach, providing a highly walkable and centrally located setting with convenient access to Downtown and the waterfront.
