The short version: there are no left-luggage lockers at San Francisco's transit hubs. Not at the Transit Center, not at Caltrain, not in BART. Here's what actually exists instead.
If you're used to European stations with a left-luggage counter, San Francisco will surprise you. The city's transit buildings — including the newest and largest one — simply don't offer storage.
| Place | Luggage storage? |
|---|---|
| Salesforce Transit Center | No — stated explicitly |
| Caltrain, 4th & King | No left-luggage office |
| BART stations | No |
| Ferry Building | No |
| SFO — Int'l Terminal G, Level 3 | Yes, staffed desk |

The Transit Center gap catches people out constantly. You arrive on a Greyhound or an AC Transit Transbay bus with six hours before a flight, and the building has a five-acre rooftop park, free Wi-Fi, 24-hour security — and nowhere to put a suitcase. What the Transit Center does have →
Commercial storage networks partner with shops, cafés and hotels that hold bags behind the counter. You book a slot on your phone, walk in, hand over the bag, and collect it later. Both operate across San Francisco. The links below are affiliate links — we may earn a commission at no cost to you. How this works →
One price per bag per day regardless of how long you leave it within that day. Simple arithmetic, and the better choice when you're storing bags for a full day or overnight — a hotel checkout at 11 a.m. against a 9 p.m. flight, for instance.
Charged by the hour with a per-bag service fee on top, and you pay when you collect rather than up front. Better value for a short gap — two or three hours between a checkout and a train — and it stops being the cheaper option once you pass most of a day.
These are genuinely different pricing models, not competing quotes for the same thing. Work out roughly how many hours you need before comparing: under about three hours the hourly model usually wins, over that the flat daily rate usually does.
Rough guide for one bag, using the published rates above. Treat these as estimates — both networks vary slightly by location and neither is a fixed tariff.
| You need storage for… | Likely cheaper |
|---|---|
| 2 hours between checkout and a train | Hourly |
| Half a day of sightseeing | Roughly even |
| A full day before a late flight | Flat daily |
| Two or more days | Flat daily |
| Checkout day at the hotel you slept in | Free — ask the desk |
Ask your hotel first, always. Most San Francisco hotels hold bags for guests on checkout day at no charge. Paid storage is for the cases a hotel can't cover — you're not in a hotel, you left days ago, or you want the bags waiting somewhere other than where you slept.
Store bags where your day ends, not where it starts. Dragging a case back across the city to collect it is the mistake that turns a free afternoon into a chore.
| If your day is… | Store around |
|---|---|
| Shopping, cable cars, downtown museums | Union Square |
| Ferry Building, waterfront, a ferry to Sausalito | Embarcadero |
| Fisherman's Wharf, Alcatraz, the northern waterfront | Fisherman's Wharf |
| Ending on Caltrain down the Peninsula | Mission Bay / 4th & King |
| Ending on a Transbay or long-distance bus | Financial District / SOMA |
| Ending on BART to SFO | Anywhere on Market Street |
Market Street is the spine. BART and Muni Metro share four stations along it, so a bag stored anywhere near Market is a short ride from Embarcadero, Montgomery, Powell, or Civic Center — and from there, straight to the airport. BART fares and stations →
SFO has exactly one storage facility: the Airport Travel Agency, in the Dianne Feinstein International Terminal on Level 3. It handles ordinary luggage plus outsize items — skis, surfboards, bicycles, golf equipment, dog kennels — with prices varying by size.
It's usually the wrong choice for a day in the city. Storing at the airport means returning to the airport to collect, then going through security anyway. If your plan is "land, see San Francisco, fly out tonight", store downtown near where you'll finish and go straight to the gate afterwards. Getting into the city from SFO →
Book before you walk over. Both networks run on partner shops with limited space, and a café that took twelve bags this morning may be full this afternoon. Booking on the app also fixes the price and the insurance cover.
Check the shop's closing time, not the network's. Your bag is behind the counter of a real business, and if that business shuts at 6 p.m. your bag is unreachable until morning. This is the single most common way storage goes wrong.
Muni and BART don't charge for luggage. There's no bag fare and no size limit worth worrying about — BART asks only that you keep bags out of doorways, and every station has elevators and wide fare gates. Storing bags is about convenience, not permission.
Don't leave bags unattended anywhere, ever. Not on a platform, not in a café while you step out, not in a parked car — vehicle break-ins are a genuine and well-documented problem in San Francisco, and a visible suitcase in a boot is exactly what's targeted.
