Why did the Five-O team move their offices in the ninth season?
The move, shown taking place in the season opener, “Nine Dragons”, was necessary because they could not do any exterior or interior filming at the palace because it was undergoing extensive renovations. So the fictional Five-O team “moved” to the old Territorial Building. Five-O moved for real, too, because their lease on the Fort Ruger studio was up. The office shots in the Territorial Building are not of a standing set — that is the REAL space in the Territorial Building, which became the temporary studio for the production.
