Malloch Building, Residential apartment building in Telegraph Hill, San Francisco, US.

The Malloch Building at 1360 Montgomery Street is a residential structure with six floors built on a steep slope using wooden frame construction and reinforced concrete foundations. Each apartment features floor-to-ceiling windows and distinctive rounded fireplaces.

Irvin Goldstine designed the Malloch Building in 1937 for contractor John S. Malloch and his son John Rolph Malloch, who were listed as architect of record because Goldstine had not yet obtained his license. Goldstine received his license in 1940, and historian Gray Brechin later identified him as the designer. In the early 1980s the building was converted from rental apartments to condominiums.

The exterior displays silvery figures by artist Alfred Du Pont showing California themes such as Spanish explorers and labor symbols. These murals give the building a distinctive visual character in the neighborhood.

The building is a private residence, so visits are limited to viewing the exterior from Montgomery Street. The street-level entrance sits at the upper edge of the steep site, while the garage and two utility floors jut out below grade to the east. The Filbert Steps, which Bogart climbs in Dark Passage, lead up nearby.

The building served as a filming location for the 1947 film noir Dark Passage, starring Humphrey Bogart and Lauren Bacall. Most visitors today overlook this connection to Hollywood history that remains part of the neighborhood's cinematic past.
