Tesla is quietly locking in more territory around its longtime Fremont factory, signing a major R&D lease and grabbing a chunk of industrial space just down the road as it races to bring the Optimus humanoid robot to life. The twin deals add engineering floor space and heavy-power manufacturing capacity that local brokers say are dialed in for robotics and advanced prototyping. For Fremont workers and suppliers, the moves make the city an even clearer hub for Tesla’s robotics ambitions.
What Tesla leased
According to the San Francisco Business Times, Tesla has taken a full-building lease for about 108,000 square feet at 45401 Research Ave., a hybrid office-and-R&D building just minutes from the main Fremont factory. Brokers told the paper the layout and utilities at the site are well suited for hardware engineering, software integration and small-batch prototyping tied directly to Optimus development.
A larger industrial play nearby
CoStar reported that Tesla also finalized a lease for roughly 267,099 square feet at the Milmont Industrial campus, a heavy-power industrial property developed by Hines and owned in partnership with Oaktree. The campus, which has been marketed for sale, offers the high ceilings and electrical capacity that manufacturers and robotics integrators look for when they need serious production muscle.
City response and context
The City of Fremont issued a statement welcoming Tesla’s choice of the city for Optimus manufacturing and clarified that mass production of the Model 3 and Model Y will continue even as portions of the campus are retooled. The city’s release said the retooling "will not result in job losses" and highlighted Fremont’s supply-chain infrastructure and skilled workforce as key reasons Tesla is doubling down locally.
Real estate and jobs angle
Market briefs show that demand for flexible R&D and advanced industrial space has been the bright spot in Silicon Valley commercial real estate, with specialized leases grabbing most of the attention in recent quarters. Cushman & Wakefield’s MarketBeat lists Fremont among the most active submarkets for specialized R&D deals, and Hoodline flagged the factory pivot earlier this year, which outlined potential local hiring and supplier impacts.
What to watch next
Investors and city officials will be watching hiring, supplier contracts and construction schedules as Tesla refits lines for Optimus, after CEO Elon Musk told investors on the Jan. 28 earnings call that S/X production space at Fremont will be repurposed for robots. The San Francisco Chronicle and other outlets reported that Tesla aims to ramp Gen-3 Optimus later this year, and Musk has publicly said he expects to begin selling humanoid robots by the end of 2027, per Axios.
