Storage unit cost in the Bay Area
This page covers San Francisco, Oakland, and San Jose in one place because the complaint is the same across the Bay: a cheap intro month, then a much higher bill. An r/bayarea thread asked for units that do not raise rent two or three times within a year. Put the advertised rate they sent you in the form. The receipt is an estimate, not a live facility quote for your ZIP.
This page does not look up a live facility rate for your ZIP. Type the advertised rent they gave you. Insurance and admin use typical estimates unless you replace them. Read the hike pattern, 28-day billing, or pick a unit size first if you still need those.
The receipt
Type the advertised monthly rent above. The receipt fills in as you type — month 1 extras and the month 4 hike bars.
