San Leandro is also nautical, which means that parts of it are somewhat historic and touch the ocean or tidal bodies of water, such as inlets and bays. Quite often, nautical areas such as these attract visitors and locals who come to enjoy the scenery and various waterfront activities.

At the end of World War II, American soldiers returned home triumphant and, with the help of the GI Bill, built homes by the millions on the edges of America's cities. These homes were predominantly capes and ranches, modest in size, but built to house a growing middle-class as the 20th century became the American century. San Leandro's housing was primarily built during this period, from the '40s through the '60s. A full 52.22% of the city's housing hails from this era. Other housing ages represented in San Leandro include homes built between 1970-1999 ( 30.62%) and housing constructed before 1939 ( 11.79%). There's also some housing in San Leandro built between 2000 and later ( 5.37%).
