Tesla’s 124-Stall V4 Supercharger in San Francisco: What the Permit Reveals About the Future of EV Charging Stops
Tesla just filed permits for one of its largest urban Supercharger stations yet—a 124-stall V4 site on San Francisco’s south side. But the headline number isn’t the only story. Buried in the permit filings is a 400-square-foot “micro-amenity” building that tells you exactly where Tesla thinks EV charging infrastructure is headed.
Here’s what the plans reveal, why the V4 platform matters, and what this means for every Tesla owner planning a trip through the Bay Area.
The Site: A Triangular Lot Off US-101
The proposed station sits at the corner of Alemany and Bayshore, on a lot currently used for yellow-cab storage. The location is strategic: it’s wedged directly against US-101, giving drivers easy off-ramp access without forcing them deep into city traffic.
The site plan shows 16 Tesla power units feeding charging posts arranged around the triangular property. That power density—16 cabinets for 124 stalls—is worth noting. It’s a ratio that suggests Tesla is building for sustained throughput, not just peak convenience.
What “V4” Actually Means for Charging Speed
The V4 platform isn’t just a new cable and a sleeker stall design. It’s the hardware foundation for Tesla’s 500 kW charging cabinets. Tesla only switched on its first full V4 station with that capacity last year, so a 124-post V4 build signals something important: Tesla is planning for the next decade of charging demand, not just today’s fleet.
Here’s how the current Supercharger generations compare:
| Feature | V3 Supercharger | V4 Supercharger |
|---|---|---|
| Max Power Output | 250 kW | Up to 500 kW |
| Cable Design | Thicker, liquid-cooled | Lighter, longer reach |
| Vehicle Compatibility | Primarily Tesla | Tesla + CCS-enabled EVs |
| Station Builds | Mostly open-air | Enclosed, amenity-focused |
| Power Cabinets | 4 stalls per cabinet | 8+ stalls per cabinet |
The practical takeaway: V4 stations charge faster, serve more vehicles, and are built with a different philosophy about what a charging stop should feel like.
The “Micro-Amenity” Building: Restrooms and Vending, Not a Diner
Tesla’s Hollywood Diner project generated plenty of buzz as a retro-futuristic vision of the charging stop of the future. The San Francisco permit tells a different story—one that’s arguably more realistic for urban installations.
The 400-square-foot structure is labeled a “micro-amenity” building. According to the permit filings, it’s a restroom-and-vending pavilion. The materials are straightforward: white aluminum composite panels, brushed stainless steel, a prefabricated metal canopy, and glass storefront entry doors.
The key insight: For an urban site, dedicated restrooms alone put this station ahead of most Superchargers. Tesla is prioritizing functional amenities over themed experiences—and that’s a signal about what actually matters to EV drivers.
This isn’t the diner concept. It’s a pragmatic response to a real problem: finding a clean, safe restroom during a charging session is consistently one of the top complaints among EV owners.
Why This Station Matters for Bay Area EV Drivers
San Francisco has a notorious shortage of convenient charging options. Many existing Superchargers in the city are in parking garages with access restrictions or in areas that feel unsafe after dark. This station addresses both concerns:
- High-visibility location directly off a major freeway
- Purpose-built amenities rather than retrofitted retail space
- High stall count to reduce wait times during peak hours
For drivers passing through or visiting the city, a 124-stall station with restrooms changes the calculus of planning a charging stop. You’re no longer gambling on whether a bathroom will be available or whether you’ll wait 20 minutes for a stall.
What This Tells Us About Tesla’s Charging Strategy
Tesla’s approach to Supercharger design has evolved through distinct phases. Early stations were utilitarian—just stalls and cabinets. The V3 era added some covered canopies and better lighting. Now, with V4, Tesla is treating charging stops as infrastructure that needs to support longer dwell times and higher throughput.
The micro-amenity building is a middle ground between the bare-bones approach and the full diner experience. It acknowledges that drivers need basic services without committing to the operational complexity of running a restaurant.
Key takeaways from the permit filings:
- 124 stalls makes this one of Tesla’s largest urban stations globally
- 16 power cabinets suggest full V4 500 kW capability
- 400 sq ft amenity building with restrooms and vending
- Prefab construction keeps costs manageable and timelines predictable
- Freeway-adjacent location prioritizes accessibility over aesthetics
Frequently Asked Questions
How fast will the V4 Supercharger charge my Tesla?
V4 stations with the new 500 kW cabinets can charge compatible vehicles at up to 500 kW, though most current Tesla models will see peak rates around 250-300 kW. The higher cabinet capacity means more vehicles can charge at high speeds simultaneously without throttling.
When will this San Francisco Supercharger open?
The permit was recently filed, so construction hasn’t started. Based on typical Tesla timelines for large stations, you can expect 6-12 months from permit approval to opening, assuming no significant delays.
Will non-Tesla EVs be able to use this station?
Yes. V4 Superchargers support CCS-enabled vehicles, and Tesla has been opening its network to other EVs across the U.S. The station’s high stall count suggests it’s designed to accommodate mixed traffic.
Is this the biggest Tesla Supercharger in California?
Not quite. Tesla has built larger stations in other states, but this would be among the largest in California and certainly the largest within San Francisco city limits.
The Bottom Line
The San Francisco V4 Supercharger represents Tesla’s practical answer to urban charging challenges: high capacity, functional amenities, and strategic placement. The micro-amenity building might lack the nostalgia appeal of the Hollywood Diner, but it delivers what drivers actually need—a clean restroom and a safe place to wait out a charging session.
If you’re planning EV travel through the Bay Area, this station is worth watching. Once operational, it should become one of the most reliable charging options in Northern California.
