Tesla officially relocated its headquarters to the site of its new Austin-area gigafactory Dec. 1, according to a filing from the U.S. Securities and Exchange Commission.

The form 8-K filing listed 13101 Harold Green Road, Austin, as the electric carmaker's new headquarters, the same site as Giga Texas. CEO Elon Musk first announced the company would relocate its main business address to Austin from Fremont, California, at an annual stockholders meeting in October. However, Musk did not specify if Giga Texas would share an address with the company's new headquarters at the time.

The decision to relocate was inspired by Tesla's expected growth in Texas, Musk said at the meeting.

"There's a limit to how big you can scale it in the Bay Area," he said. "Here in Austin, our factory is like five minutes from the airport and 15 minutes from downtown. And we're going to create an ecological paradise here, surrounded by the Colorado River. It's gonna be great."

Production out of the factory, which is slated to manufacture the new Tesla Cybertruck, other vehicles and batteries used in the company's cars, is set to begin by the end of the year, Musk confirmed in October, with production in full swing by the end of 2022.
