Storage unit prices in Trenton, NJ

Most Trenton branches advertise several 5x5 units at once, and the second one costs 29% more than the first at the same address. The $34 headline is the entry price, not the shelf.

The market also holds Lawrenceville, Mercerville and Monmouth Junction.

No branch on this page starts a 5x5 below $34, on Olden, or above $71, on Parkside, a band of just 109%.
Only 6 locations feed this page, so a single branch moves every figure on it further than it would in a bigger market.
That $34 rests on one address. The next cheapest branch, US Highway 1 in Monmouth Junction, wants $50, so a unit gone from the first is a 47% jump rather than a short walk.
Space is cheapest by area in the 10x20, at $0.64 a square foot, and dearest in the 5x5 at $1.36.

Where these numbers come from. 22 advertised prices read from Public Storage's own published listings across 6 locations, last checked 2026-08-12.

Online rate vs regular rate. Every listing publishes two figures. Measured across thousands of observations, the regular rate is 1.5× the online rate at the median, with 88% inside 1% of that and none outside 1.40–1.60×. That is a pricing rule, not a second quote. The online rate is the promotional price for booking on the web; the regular rate is what the unit reverts to. Budget on the regular rate. Comparisons here hold the basis constant, so the gap between locations is real either way.

These are advertised rates for new rentals, not quotes — Public Storage states prices are not guaranteed and they move with availability. Insurance, admin fees and limited-time offers are not included.
