The house withstood the 1906 earthquake with only slight damage . However , the home was threatened by the devastating fire , which followed the earthquake and destroyed about 40 % of San Francisco . The Haas family watched the fire from the roof of their house , but was soon forced to evacuate by city authorities . So the family , along with most other San Francisco residents , went to the nearest public park , Lafayette Park , to camp out during the emergency . Later , they temporarily moved to a large house in Oakland while the City was reconstructed
