What a storage quote leaves out

A quote is one number. Between it and the amount that leaves your account sit three gaps this database can measure — and one it cannot see at all.

None of this is concealed. Public Storage publishes its rates on every location page in a format machines can read, which is how 52,892 of them ended up in this database in an afternoon. The trouble is compression. A search result gives you one figure, and that figure is the promotional rate, for the cheapest unit of that size, currently listed at that branch, for a period nobody states. Four qualifiers, and each one moves what you pay.

The rate has a second value printed beside it

Every listing carries two figures: the online rate you book at, and the regular rate. Across all 52,892 observations the higher lands within $1 of exactly one and a half times the lower, and since every price here is a whole dollar, that $1 is rounding. The rule does not bend by branch, market or size — a different multiple would miss by tens of dollars on a $221 unit, and nothing in 4,617 locations misses by more than that.

The multiple is easier to argue with than the money, so here is the money over a year:

One thing about how that pair gets described. Coming down from the regular rate to the online rate is a 33% discount. Going back up from the online rate to the regular rate is a 50% increase. Both sentences describe the identical two numbers, and the second is the one that applies to you, because you start at the lower figure and move up from it.

Nothing published says how long the lower number lasts

This is the gap we cannot close. No field in any listing we read records the length of the promotional period, so this database has nothing to report on it — no median, no range, not even a distribution to caveat. An assumed promotional length silently sets the whole annual figure, and that is the sort of number that gets repeated once written down, so we will not invent one.

What can be stated are the bounds. A 10x10 at the median of 4,417 branches is $95 a month advertised and $143 after reversion. Twelve months entirely at the first is $1,140; twelve months entirely at the second is $1,716. Your first year sits between those, and the only way to learn where is to ask the branch — about the specific unit, for the reason below.

The advertised figure is one unit out of several

More than half of what looks like a single price is not one. Of 27,404 branch-and-size combinations, 14,633 — 53.4% — carry more than one distinct unit of that size at that location; for the 10x10, 69%. These are not duplicate rows: one branch in Yukon, OK lists 15 separate 5x10s from $23 to $39. That is the extreme; the typical case is not small either: at the median branch listing more than one 10x10, the dearest sits $17 a month above the cheapest, a 19% gap inside one building.

The advertised number is the bottom of that stack. If the cheapest unit has gone by the time you call — and it is the one everyone is calling about — the next one up costs a median of $9 more, about 11%.

What separates units in a stack is normally climate control, floor level and door type. This database cannot tell you which is which: the field that would record it is populated on 241 of 52,892 rows — 0.46%, confined to 20 locations from one re-crawl. So where a table here shows a branch's cheapest 10x10, read it as the cheapest thing called a 10x10, not as like for like.

What this database does not contain at all

Insurance, administration fees, deposits, lock purchase, late fees, taxes: none of it, not one row. The ingester reads the operator's structured price offers, and those carry a rate and nothing else. We have no figure to publish and no defensible way to estimate one, so what a first payment totals is something this site cannot tell you. If another storage site quotes an average admin fee, ask where it was measured.

Also absent: history. Every observation was read on one day, 2026-08-12, so what happens to a sitting tenant's rate at month nine is invisible here, and anyone claiming to know it from a single crawl is guessing. Prices are re-read weekly and stored append-only; that answer is coming, it is not here yet.

Four things worth asking before you sign

Each answers a gap named above, and all four are answerable at the counter.

• How many months the online rate holds, and what it becomes afterwards — for the unit you are being given, not for the location.
• Whether the unit at the advertised price is the one being rented to you, or whether it has gone and you are being quoted the next one up.
• What that unit physically is: floor, climate control, door type. On a 5x5 that choice is worth $5 a month at one branch; on a 10x30, $38.
• What the first payment totals with everything included, rather than what the monthly rate is. That is the one figure here no dataset on this site can check for you.
