Following a project proposal originally brought in 2020, new approvals have come through for the demolition and redevelopment of a 4.9-acre site at 3700 California Street in San Francisco. While original city approvals were met in 2020, the project has not yet begun its demolitions, awaiting further environmental approvals and plan revision approvals. The project would bring an injection of housing to the area between Pac Heights and the Inner Richmond neighborhoods, and developers are looking to begin construction as soon as possible.
TMG Partners has proposed the demolition of five of the six existing hospital facilities and the adaptive reuse of the Marshal Hale Hospital building, creating a combination of single and multi-family residential properties. The project will also retain the existing nine-unit residential building at 401 Cherry Street, bringing the total development area to 493 dwelling units.
The new multifamily buildings are to be constructed above below-grade parking, allowing for ease of vehicle access, while the 15 single-family properties are to be divided into private lots with private parking garages. Between the two types of housing, the units would range from studio to four bedrooms. The units will also be supported by shared onsite amenity spaces, including landscaped common areas, a fitness facility, roof decks, and other shared facilities.

The buildings would range from three to seven stories, with a maximum height of 80 feet. Taller buildings are to be intermixed with shorter buildings, breaking up the total block height. Each building would have a unique and variable façade design, with styles and blocking consistent with the surrounding neighborhood.
The building’s location is already a primarily residential area of San Francisco, and the conversion of the property from medical to residential will not have a significant impact on the average building usage. In addition to the building’s vehicle access, the blocks are supported by Muni bus options, and they are within walking distance from several parks and retail options. As a result, it is unlikely that the new development will have major impacts on the culture or livability of its surroundings.

I‘m absolutely loving the spread of housing here. Some people want to live in a smaller building than others and this really nails the housing diversity, while slightly jumping in average height of the surrounding neighborhood. I‘m hoping this gets shovels in the ground soon.
Amazing looking project. Seems like a super thoughtful and appropriately contextual approach with the right amount of density. Hope to see more of this kind of building throughout the rest of the city.
YES! What a beautiful improvement to this neighborhood. Hope it happens!
