Hollyhock House’s landmark status did not protect it from the ordinary trouble of water getting inside. After years of intrusion, alterations, and damage from the 1994 Northridge earthquake, a major restoration addressed the building’s condition. Work begun in 2010 repaired and prevented water damage, strengthened the structure against earthquakes, restored historic features, and reversed earlier changes. The house reopened in February 2015. Behind the pleasure of seeing Wright’s rooms again was a less visible achievement: making the building better able to survive the conditions that had worn it down.
