New Tesla Gigafactory projects revealed through latest building permits
Teslarati has learned that the total value of all building permits issued for the Tesla Gigafactory now stands at $386 million, or $63 million more than the last time Jack Cookson of BuildZoom checked in with the local building inspector’s office.
Perhaps the most surprising bit of information is that a permit was issued recently for a “temporary tent structure” for a “special event” costing $300,000 likely to be used for the Gigafactory Grand Opening party. We recently spotted the massive tent, the size of two NBA basketball courts, in newly captured aerial photos of the Gigafactory.

“Section F Expansion” assumed to be one of the two new additions at the battery plant claimed the largest single permit by dollar at $22 million. There was also a permit issued for “seismic anchoring” totaling $9.4 million. Presumably, seismic anchoring is part of the foundation work for Section F.
We have to keep reminding ourselves that the current building represents less than 15% of the total size of the Gigafactory when finished. All the exterior walls except the main wall in front are temporary, designed to be broken through as new sections are added.
We’ve provided all of the notable permits filed for the Tesla Gigafactory via BuildZoom.
- The total value of work since we last checked in has been 63 million dollars, bringing the total for the entire project to 386 million dollars.
- First, and perhaps most relevant to the opening, is on July 18th Tesla filed a permit for a “temporary tent structure” for a “special event”. While I can’t be sure, the $300,000 tent might be for the grand opening.
- The biggest single permit was a 22 million dollar permit for the “Section F Expansion”.
- The first permits related to Panasonic work were issued to Tesla on June 28th and July 13th. The two permits are for the installation of Panasonic tools. The two permits were both designated to section B/C and totaled 16.2 million dollars.
- There was also 14.4 million dollars worth of addenda to sections D/E.
- There was 9.4 million dollars in seismic anchoring issued in permits.
- There was 350,000 dollars across two permits for contractor lunch tents, perhaps related to the increase in construction workers they recently took on.
- There was also a parking expansion and while I don’t know what a “Nitrogen Yard” is there was a permit for one.
As Panasonic executive vice president Yoshihiko Yamada explained at the Tuesday news conference, his company is fully committed to its partnership with Tesla. Panasonic took out two building permits of its own recently, both covering the installation of its proprietary machines and tools in sections B and C. The two permits together total $16.2 million.
The local building inspector’s office also recorded permits totaling $14.4 million for additional work in Sections D and E and $9.4 million in other miscellaneous work recently. They include an expansion to the parking area. Tesla made sure there was parking for 2,000 cars in time for the grand opening this weekend.
The pace of construction at the Gigafactory is accelerating. Workers are now busy seven days a week, working two shifts a day. In order to accommodate their needs, Tesla has applied for permits for two contractor lunch tents worth a total of $350,000.
Finally, Jack Cookson reports a permit application for a “Nitrogen Yard.” Exactly what that is or what role it will play in the production process remains unclear.
Although the two vehicles are built for completely different use cases, Tesla utilized engineering expertise while developing both the Cybercab and Semi to build a thermal architecture that would fit both vehicles. Of course, with some slight revisions.
The development was noted by Lars Moravy and Dan Priestley last week at Tesla’s Semi Handover event in Sparks, Nevada, where the company showed off its dedicated production facility for the Class 8 truck.

Tesla’s decision to develop one thermal architecture for both the Cybercab and Semi is one of the more revealing engineering choices in the company’s 2026 lineup:
“We designed it at the same time we designed the Cybercab and we said okay we’re going to take our most efficient vehicle and our biggest vehicle and we’re going to take one thermal system and make it work for both.”
Core parts, meaning the compressor, pumps, and heat exchangers, are shared, with only modest changes to cooling-loop sizing and a larger radiator on the truck. The result, they said, is a compressor and thermal stack already proven across millions of miles, delivering “reliability from day one.”
Priestley also highlighted a practical payoff of the indirect design:
“There’s no AC lines, there’s no refrigerant lines…It comes from the factory fully charged, sealed with refrigerant, and it just exchanges coolant. It doesn’t actually run refrigerant up to the front of the vehicle.”
This eliminates potentially leak-prone plumbing that would otherwise require hands-on service, reducing overall uptime and potentially cutting into business margins. The megamanifold runs cabin HVAC and every powertrain heating and cooling loop at once, recapturing waste heat from motors and the battery instead of dumping it the way a diesel engine does.
The approach is just the latest chapter in a continuing story of stretching thermal solutions across wildly different vehicles. Model Y’s Octovalve evolved into the Super Manifold used on Cybertruck, and later Model S/X refreshes. Cybercab then introduced Supermanifold V3, which Tesla says is 80 percent automated to build and 38 percent more efficient than typical automotive thermal systems.
This thermal system is also shared with Cybercab – one thermal system for both our most efficient vehicle & our biggest vehicle

Tesla has done the same with the 4680 cells, both being utilized in the Cybertruck and Semi, and with heat-pump compressors that Priestley noted were already common across the passenger-car fleet.
Concurrent development of crucial vehicle elements buys scale and reliability that a truck-only thermal system could not match. High-volume passenger car parts are cheaper and more accessible, which can give fleets a sealed, low-maintenance loop of operation from their first day of operation.
For owners and operators, that translates into less energy spent on cabin heat in the colder months, fewer refrigerant-related repairs, and a thermal architecture already stress-tested at passenger-car volumes before the first high-volume Semi left the lines in Nevada.
Tesla CEO Elon Musk certainly tipped off some details of the Tesla Roadster event with a broadening of information regarding the company’s decision to delay the unveiling for two weeks.
For years, people have speculated about what the Roadster will be capable of. While there have been plenty of things said about what it *could* do, we have not seen or been told by Tesla what it will actually be capable of.
However, over the past few days, Tesla’s weather updates have truly pushed the speculation into Plaid Mode, basically all but confirming the car will have some sort of aerial capability — whether that would be hovering or fully flying remains to be seen — but it definitely seems that it will be able to leave the ground intentionally.
“Because this event can only be held outdoors…”
Tesla posted on Monday that it would delay the Roadster event until October 15, and it indicated that it had to do this because the event “can only be held outdoors.”
With the potential SpaceX collaboration to develop cold-gas thrusters that will help the vehicle go airborne, doing this indoors is probably not a safe, or even plausible, possibility.

We’ve been tracking the weather closely with local meteorologists, but given the severe conditions predicted & because this event can only be held outdoors, we’ve made the difficult decision to reschedule.
New date is October 15. Additional details to…

FAA Airspace Restriction
The FAA gave Tesla a Temporary Flight Restriction (TFR) for 10,000 feet above ground level, much higher than the typical 2,000-foot restrictions that are usually placed at SpaceX’s McGregor, Texas site.
Tesla Roadster event requires restricted airspace, and the FAA obliges
Some have said that this massive increase is due to Tesla’s need to restrict unauthorized drone use for spying on the event.
Elon Admits High Winds
“Due to high winds, the new Roadster demo is postponed by 2 weeks,” Musk said in a post on X yesterday.

A reply reading, “What’s strong wind got to do with a car demo with four grounded wheels?” was directly below Musk’s post, satirically and sarcastically probing for more details.
All signs are pointing toward an aerial demonstration for the Roadster.
Tesla has secured $30 billion in fresh credit lines from Citibank and Wells Fargo in an effort to scale its biggest current projects.
Tesla agreed to a $20 billion three-year delayed-draw term loan facility from Citibank, it announced on Tuesday. Additionally, it signed a five-year, $8 billion revolving credit facility and a $2 billion, 364-day term credit facility with Wells Fargo.
In a filing with the Securities and Exchange Commission (SEC), that it “may draw” from the $20 billion delayed-draw term “from time to time” and “no more than ten times during the 18 months following the closing date.” This loan matures on September 29, 2029.
The five-year revolving facility from Wells Fargo will also be accessed by Tesla “from time to time,” and will become due and payable on September 29, 2031. Tesla can request two separate one-year extensions.
On the $2 billion, 364-day revolving loan, it becomes due and payable on September 28, 2027. Tesla can also increase its additional commitments to an additional $4 billion across the Revolving Facilities. This would increase the total facilities to $14 billion. Tesla said it does not plan to utilize any of these loans in 2026.
Tesla plans to utilize the money to help prop up its ambitions to scale its biggest products, each of which is either in early launch phases or still in development. Of course, we’re talking about Cybercab and Semi, which have launched, and Optimus, which is still under heavy development and working toward initial release.
All three Tesla products have one thing in common: they’ve all required Tesla to build new manufacturing lines for them.
For the Semi, Tesla built a brand new factory in Sparks, Nevada, adjacent to the Tesla Gigafactory. For Optimus, Tesla sunset Model S and X production at the Fremont Factory, which brought an end to the two flagship models, thus creating manufacturing space for the humanoid robot. Finally, Cybercab is being built at Gigafactory Texas and officially entered production earlier this year.
The cash will help Tesla bolster its finances for the continuing development of these products. Tesla said that it forecasts its CapEx to be over $25 billion, up from just over $8.5 billion last year. These loans surely help with that spending.
