1770 Fort Stockton Drive in Mission Hills is designed in the Prairie style.

4437 Alhambra Street in the Sunset Cliffs neighborhood was constructed in 1929 and illustrates the Spanish Eclectic style.

The land at 1398 Lieta Street in Clairemont is designated under Criterion A as a special element of Mission Bay due to the Japanese agricultural practices here during the 1930s through the 1950s, and the associated property rights restrictions, including the California Alien Land Law of 1913. Aizo and Komume Sogo, and their family, lived on and farmed this property as early as 1937. Forced into internment camps during WWII, the Sogos returned to farm this land in 1945. Aizo and Komume are two of the first five Japanese to be granted citizenship in San Diego County, enabling them to legally purchase their land in 1954.

The residential high-rise at 666 Upas Street in Hillcrest is designed in the International Modern style by Master Architect William Krisel.

The board also designated the building under Criterion D, while establishing Krisel as a Master Architect.

3155 Second Avenue in Bankers Hill, dating from 1904, was the first house built on this block and illustrates the folk Victorian style. Designated under Criterion A as a special element of the neighborhood, this building's significance derives from Theodosia B. Conner, a married woman who purchased and developed this property, which was a rare occurrence during the early 20th century. The house is also potentially significant as the residence of Master Architect Eugene Hoffman, from 1923 through 1933. Hoffman's enhancements include the balconies and doors leading onto them, and the rear second-story deck.

887 Golden Park Avenue in La Playa represents the Organic Geometric style and was designed by Sim Bruce Richards in 1954. Designated under both Criteria C and D, this is significant for the architectural style and as the notable work of a Master Architect. Character defining features include the angular massing, site-specific design that responds to particular views and vistas, vertical wood siding, and geometric detailing on the large beams, fenestration, and screens. This resource exemplifies Richards' principles of organic design and integrates Asian influences, such as the flared rooflines, indoor-outdoor relationships, and paper-covered lattice screens, also known as shoji screens.
