What San Jose homeowners should know
San Jose's mild Mediterranean climate is easy on homes, but earthquakes are the main hazard: the city sits between the San Andreas, Hayward and Calaveras faults. Much of the housing was built during the 1950s–1970s Silicon Valley boom, so original plumbing, electrical and roofs are often due for replacement.
Summer heat in the Santa Clara Valley is stronger than in San Francisco, making AC more important, and expansive clay soils in parts of the valley can move foundations.
