Tesla Fremont Plant, California

Tesla’s only vehicle assembly plant in the USA is in Fremont, California. It was built in 1962 by General Motors, and grew over time. Starting in 1984 it was operated as the New United Motor Manufacturing Plant, a partnership between Toyota and General Motors, making things like Toyota Corollas, until 2009, when it was the last car assembly plant in California to close. In 2010, Tesla bought it, reversing the trend, though it took a while for it to grow into the space, which is usually listed as somewhere between 4,300,000 and 5,500,000 square feet.
