  2. Major damage 25 to 50% damaged 62
  3. Minor damage 10 to 25% damaged 66

Buildings CAL FIRE inspected after the fire, by how badly each was damaged. Inspectors record homes, businesses and outbuildings within 100 meters of the fire, and cannot always reach every one, so the counts can differ slightly from other reports.
