Project Titan, SixtyEight & SG5: Inside Apple's top-secret electric car project : The City of Sunnyvale has issued a number of permits to Apple at the site, proving the company leases at least three of the campus's seven properties. Apple has taken residence in the building with the largest footprint, which is outfitted with a battery room, reliability lab, water ingress lab, 2,000 gallon tank, conference room, break room, computer labs, and test chambers. Outside are bicycle parking facilities, while two large loading areas flank a row of overhead doors installed to the rear of the building.
