The construction process was not without difficulty . Wright 's initial plans called for flat terrain , but the lot the Hannas purchased was hilly . Cost overruns meant that the original $ 15,000 price tag ballooned to over $ 37,000 ( $ adjusted for inflation ) . Additionally , Hanna discovered that his lot encompassed a portion of the San Andreas Fault . Wright , whose Imperial Hotel had survived the 1923 Great Kantō earthquake , was undaunted . Unfortunately , the home was severely damaged by the 1989 Loma Prieta earthquake . Although that branch of the fault was inactive during the quake , the foundation and chimney were essentially unreinforced and likely would have collapsed if the earthquake had lasted longer . A major 10-year restoration was completed in April 1999 , this time with seismic reinforcement
