    **Robbed at Extra Space Storage** Update: go to Facebook. It seems to be a trend around the United States with this company. Search for shot and forgot. Gentleman talks about extra space storage in Austin, Texas. Then he does some investigate work. Several storage unit were robbed, and I am extremely disappointed with how Extra Space Storage handled the situation. Clients were told that there was nothing they could do regarding the security cameras, and they refused to investigate or review the footage to try to identify who was responsible. After such a serious security incident, I would expect the facility to provide some assistance or at least make a genuine effort to investigate what happened. Instead, nope. People chose a storage facility expecting our belongings to be reasonably secure. Having property stolen is bad enough, but the lack of assistance afterward has made the experience even worse. I strongly encourage anyone considering Extra Space Storage to research the facility's security history and read reviews carefully before storing their belongings there.

    I am also among the 15 units broken into at this location. I would likely feel better about it if there were more answers about when, who, and how this happened but I was instead given a lot of, "We aren't sure," responses with regards to the event. Break-ins may have been occurring up to a month ago; there is no footage and no other info. There were equally no assurances on how to keep my items secure going forward. The individuals who broke in likely went over the top of the unit and cut the lock from behind. I feel this is confirmed by the pieces of my lock found in my unit. Because of the responses (or lack thereof), I no longer feel safe and do not plan to maintain a unit here and I equally cannot recommend this location to anyone. I do want to recognize that the staff in the front office are extremely polite, but politeness does not keep my items secured.

    22 Sept 26: I was notified my indoor unit was broken into along with several other units throughout the facility. Someone climbed over the interior walls that separate the units and unbolted the door locks from the inside. I asked if the police were called / Answer: No, there was no damage to our facility so we didn’t call them I asked if they have video of the theft / Answer: “We did not review the video because we do not know when it happened” Website: “SAFE & SECURE Enjoy peace of mind while storing what’s precious. We’ll take care of your stuff as if it were our own.” 24 Sep 26 To ExtraSpace - Thank you for the public apology. What actions are you taking to investigate the incident and what actions are taken to prevent future incidents?

    ⭐ 1 STAR — DO NOT STORE YOUR VALUABLES HERE I strongly recommend GOING SOMEWHERE ELSE. I regret trusting this facility with my belongings. I had expensive collectible items stolen from my storage unit, and the way this situation has been handled has been incredibly disappointing. When you're paying a company to store your property, you expect reasonable security and for serious theft concerns to be treated seriously. That has not been my experience. One of my biggest concerns is the security setup. The facility only allows those small, inexpensive cylinder-style locks on the units. Customers are not given the option to use their own high-security lock or add a heavier-duty lock of their choice. These types of locks provide me very little confidence when you're storing expensive property. After having valuable collectibles stolen, the fact that customers have limited options for securing their own units is extremely concerning. I also asked about reviewing security footage to determine when my belongings may have been stolen and was told that I would need a subpoena to obtain that information. Whatever the facility's policy may be, being told that I couldn't review information that might help determine what happened left me with even more questions and frustration. Then there's the temperature issue. Temperatures inside the facility have been reaching approximately 79–82°F. If you're storing valuable collectibles, memorabilia, electronics, or other temperature-sensitive items, think very carefully before putting them here. Those temperatures can be a serious concern for certain types of stored property. What makes this experience even more frustrating is the inconsistency in how things are handled. Months before my belongings were stolen, I accidentally left two pieces of cardboard outside my unit. The facility charged me a $50 trash-removal fee within 24 hours. So apparently two pieces of cardboard were important enough to warrant a $50 charge, but after expensive collectibles went missing, I did not feel that same level of urgency or concern regarding my property. At this point, between the theft of valuable belongings, limited lock options, concerns about security, restricted access to surveillance information, temperatures reaching 79–82°F, and the way my concerns have been handled, I cannot recommend this facility. If you have anything valuable, especially expensive collectibles, I would think twice before storing them here. Ask about the security cameras, who can access the footage, what kind of locks you're allowed to use, what the actual interior temperatures are, and what happens if your property is stolen. I wish I had asked those questions before trusting this facility with my belongings. Don't make the same mistake I did. Take your valuables somewhere else.👎
