purchased the 17000 sq ft (1,579.4 m²) property and lived in it for ten years. After that, he rented it out for a time, and in 2000, he stopped maintaining it. In 2004 Jobs stirred Woodside preservationist controversy by applying for a permit to tear the historic landmark down to build a smaller house. A judge ruled against demolition in early 2006. Jobs appealed the decision. In April, 2007 the California State Supreme Court refused to hear the Jobs appeal, which meant he could not raze the house. Nonetheless, Jobs won approval to demolish the Jackling House from the Woodside Town Council on May 13, 2009.
On April 29, 2010 the architectural-historical preservationists group Uphold Our Heritage appealed the March court decision to allow the Woodside to issue a demolition permit, submitted by the group's attorney Doug Carstens. The appeal put an "automatic stay" on the issuance of demolition permits. "If that (Yoho family relocation permits) works out, and it looks like there's a lot of promise to that working out, then it won't be necessary to pursue the appeal," he said. "We've always been in favor of relocation and restoration." "We respectfully disagree with the court's decision, and we have all along." Carstens said.
The house was demolished in February, 2011.
