Top 6 tidbits about Tesla’s Gigafactory revealed through building permits
It’s no secret that Tesla’s $5 billion dollar Gigafactory 1 located just east of Reno, Nevada will be a critical component to the company’s goal of scaling mass production of batteries for its upcoming Model 3 and Tesla Energy product line. We know the Gigafactory will be one of the largest buildings in the world projected to occupy 13.6 million square feet, and we know the factory will be powered by renewable energy sources, with the goal of achieving net zero energy. However, construction permits filed by Tesla provide even more interesting insight to Gigafactory 1 that you may not already know.
Here are the top 6 tidbits of Tesla’s Gigafactory as revealed through building permits received by Tesla. Information is provided courtesy of analyst Jack Cookson of BuildingZoom.
1) July 29 launch event attendees may witness battery cells being made
Construction permit #0934363 indicates that the $51 million dollar “Battery Cell Manufacturing Equipment Installation” project is estimated to be complete on July 20th. This means that attendees of the highly anticipated July 29 Gigafactory ‘Grand Opening’ event may actually have the opportunity to see battery cells being manufactured.
2) Tesla can do it all
Tesla filed for building permits themselves as opposed to using a General Contractor. According to a report put together by Cookson of BuildZoom,
“Something we found different about this project is that Tesla filed the majority of their own building permits and is actually the contractor for the project. This means, that Tesla had to acquire a contractor license in Nevada and has taken on far more work than if they had just hired a General Contractor.”
This may not be such a bad idea considering Tesla’s recent involvement in a foreign worker scandal under poor supervision and management by factory sub-contractors.
3) Tesla’s Gigafactory is designed for earthquakes
Most buildings rest on a single foundation, however the enormous rectangular shaped Gigafactory rests on four individual foundations. This is designed so that each section of the building can shift independently of one another in the event of an earthquake.
4) The Gigafactory doesn’t stop growing
Tesla received a permit to expand the Gigafactory with a 4th Area ‘D’ and 5th Area ‘E’. The $63 million dollar D and E project is scheduled to be complete by the end of the year. Tesla’s enormous Gigafactory is currently only 14% of the total planned floor space, but will reach an astounding 13.6 million square feet when complete.

5) Tesla donated a fire truck to the local fire department
Tesla spent a total of $4.7 million dollars on fire safety, including a permit for a fire command center. Part of that included a donation of a fire engine to the local Storey County, Nevada fire station.
6) Giant refrigerator + water tank twice the size of an olympic pool
1 of the 84 permits filed indicates that the Gigafactory will have a giant chiller yard which will presumably be used for testing batteries while keeping them in a cool state.
The factory also has a a 1.5 million gallon water tank on site that is more than twice the size of an olympic sized swimming pool. Details within the permit do not indicate what this water tank will be used for.
Tesla has updated its Robotaxi app so riders can pick which vehicle they want before they book. The latest in-app screens now show two options side by side: the two-seat Cybercab and the four-seat Model Y.
A screenshot circulating Thursday shows the change in practice. In Austin, a rider could choose a gold Cybercab for two people or a Model Y for four. Tesla’s updated description calls Cybercab “our first purpose-built autonomous vehicle,” designed for safety, accessibility, and comfort, and says the lineup is available only through the Robotaxi app.

The distinction is more than cosmetic, and it’s important to note that Robotaxi refers to the platform, while Cybercab refers to a vehicle.
Model Y Robotaxis have carried the service since it opened in Austin in mid-2025 and later expanded to Dallas, Houston, and parts of Florida. Those vehicles are converted production SUVs that still have steering wheels and pedals.
Cybercab is different. It has no driver controls, butterfly doors, a low seat height meant to work with wheelchairs, extra trunk space for assistive devices, and braille on the handles. Tesla has registered dozens of the two-seaters with Texas regulators in the days leading up to its September 3 Austin event.
Giving riders a choice lets Tesla match the vehicle to the trip. Most rides involve one or two people, which is where Cybercab is meant to be cheaper and more efficient to operate. Groups of three or four, or anyone who needs more space, can still request a Model Y.
The same app handles booking, payment, cabin settings, and, on Cybercab, features such as phone-based door opening and in-cabin voice controls.
The update does not mean every city suddenly has both cars available. Cybercab support is listed for Austin first, and the purpose-built fleet is still small compared with the existing Model Y roster. Even so, the app change marks a shift from a single-vehicle pilot to a mixed fleet.
Riders can now choose between the compact, purpose-built robotaxi and the familiar SUV that launched the service.
Tesla Cybercab sightings are broadening far and wide, well outside of downtown Austin, Texas, with autonomy in focus as the company plans to launch the all-electric, two-seater this evening in the Lone Star State.
Tesla is set to launch Cybercab to a small group of people this evening in a dedicated event in Austin, Texas. Public details on the event are relatively slim.
However, Tesla’s focus on Cybercab falls well outside of the downtown Austin area and is expanding well across the United States as things continue to move quickly with the company’s autonomous efforts in 2026. Today, various images of Cybercab fleets in interesting locations have started to circulate.
The most notable is a fleet of at least 20 Cybercabs at Miami International Airport in Florida. Spotted last night, the fleet is expansive and is indicative of a looming release of Cybercabs once regulatory boxes are checked off.
Tesla has already been operating the Robotaxi platform in Miami for several months, but this Cybercab fleet at the airport could be joining the ride-hailing platform as approvals arrive:

Another fleet of Cybercabs was spotted at the Devon, PA showroom just outside of Philadelphia. We have seen several Cybercab units testing around the Philadelphia Metro Area, which is interesting considering Tesla does not have any active Robotaxi geofence in Pennsylvania.

Philadelphia would be an ideal location to test ride-hailing due to its dense tourist population, large, sprawling city layout, and to compete with other ride-hailing companies that operate in the city.
Expansive fleets of Cybercabs will be popping up in and around major cities throughout the rest of the year, if we were betting on it. Tesla has made it obvious that the Cybercab rollout will be aggressive and fast-paced, but within reason. Tesla is still prioritizing safety, so these testing phases will likely go on for some period of time before more members of the public are able to snag a Cybercab for a personal chariot.
The Tesla Model Y L is arguably the most hyped trim of the all-electric crossover, other than the Performance configuration that comes with white-knuckle speed and sports car-level handling.
However, it is not all perfect. Tesla owners in China who took delivery of the Model Y L, denoted with an L to highlight its longer wheelbase, are experiencing what they are referring to as “collapsing” of the rear wheels, as suspension issues appear to be an issue with some of the builds.

The gap between the wheel arch and tire has narrowed to the point that “not even a single finger” could fit, according to a report from Car News China. The failures are not tied to a specific mileage, as one owner said that after just 9,000 kilometers (5,600 miles), they noticed the suspension issue when their car was fully loaded.
Another one had the issue at 30,000 kilometers (18,640 miles) and noticed that the wheel gap shrank to two fingers, so not as drastic as the person who reported a similar issue at 9,000 km.
Tesla Model Y L is gaining momentum in China’s premium segment
Along with the visual recognition of the issue, others are saying the sagging is causing abnormal wear on the inside of the tires. Extra weight and instant torque already provide additional stress on the tires in electric vehicles during normal operation, so it is no surprise that this is another complaint.
There has been no recall issued by Tesla, and the company has not yet publicly acknowledged the issue.
Some are suggesting that owners use a “finger test” to self-diagnose whether there is an issue with the suspension. There should be four fingers between the tire and the wheel well; anything less than that starts to get dicey.
