If you operate in the Sun Belt, you already feel it. A new facility went up two exits down. Your street rate slipped. The phone rings a little less. You're not imagining it, and you're not doing anything wrong. You're absorbing a supply wave.
Here's the map, and then here's the part that matters: what you actually do about it.
The numbers
Supply peaked in 2023, when developers delivered about 78 million square feet of new storage nationally. A lot of that landed in the same handful of metros.
It's still working through the system:
- San Antonio adds roughly 656,000 square feet in 2026, the most of any U.S. market.
- Houston adds about 430,000.
- The most oversupplied markets cluster in Texas, Florida, and California, plus Charlotte, Denver, Tampa, and Atlanta.
- Recovery in the affected markets runs from late 2026 into 2027.
So if your facility sits in one of those metros, you're competing on price right now, and you will be for another year or more. That's the bad news, and there's no spin on it.
The good news, and it's real
The wave is cresting, not building. The pipeline is shrinking fast:
- Construction starts are down about 21 percent from the 2023 peak.
- Annual supply growth is projected at just 1.5 percent through 2027.
- The pipeline drops from roughly 51 million square feet in 2026 to about 44 million in 2027.
New supply is the kind of problem that fixes itself, slowly, as long as you're still standing when it does. The facilities that struggle aren't the ones in tough markets. They're the ones in tough markets that also gave up on getting found.
You can't make supply disappear. Here's what you control.
There's a line from the market research I keep coming back to, because it's exactly right: "You can't make new supply disappear. You can control how your facility is priced against competitors in real time, how quickly you respond to leads, how efficiently you manage delinquencies, and how your facility presents to a tenant searching online at 11pm on a Sunday."
That's the whole strategy for an oversupplied market. Four levers, all yours:
Price against the actual competition, in real time. Not against last year. Against the rate the new facility two exits down is quoting today. If you're not watching their rates, you're guessing. (Your web-to-street rate spread is a free read on how much pricing power you actually have.)
Answer leads fast. When supply is tight, the renter has options. The first operator to call back usually gets the unit. Minutes matter more in an oversupplied market than anywhere else.
Present better at 11pm on a Sunday. That's when people search. If your Google profile is half-filled and your reviews trail off, you lose to the new facility with fresh photos and a review program, even if your place is nicer in person. Especially then.
Don't bleed the back door. Every delinquency you don't manage is an empty unit you're competing to refill against new supply. In a soft market, keeping the tenants you have is half the battle.
Notice what's not on that list: out-building the new guy, or winning a price war to the bottom. You can't, and you shouldn't try. The move in an oversupplied market isn't to be the cheapest. It's to be the easiest to find and the easiest to rent from.
The honest read
A soft Sun Belt market punishes coasting. The operators who lose units in 2026 mostly aren't losing them to the new facility's lower rate. They're losing them to the new facility's better online presence and faster response, while telling themselves it's the market.
The market is real. It's also temporary. Supply growth falls to 1.5 percent a year and the affected metros recover into 2027. The question is whether your facility is the one renters find and pick during the squeeze, or the one quietly losing the map while it waits for the market to come back.
Where StorageAds fits
We built StorageAds to run those levers for our own facilities: watch competitor rates, get found on the searches that fill units, respond to leads fast, and see what's actually working, all in one dashboard. It's built for exactly this kind of market, where being found and being fast is the difference.
If you're in a Sun Belt metro, start with where you stand. Run the free audit. It shows your local ranking and reviews against the facilities nearby, including the new ones, in about two minutes.
