South San Francisco's housing includes post-war single-family neighborhoods, hillside homes with panoramic views, and modern developments near downtown and the biotech corridor. Many homeowners are upgrading to efficient heat pumps that provide year-round comfort-heating for cool Peninsula mornings and optional AC for increasingly warm days.

South San Francisco's Peninsula location creates a comfortable coastal climate with cool marine layer mornings (often 55-65°F), mild afternoons, and occasional warm inland days reaching 75-80°F.
