    Read some helpful reviews of Extra Space Storage, shared by real renters with genuine experiences and honest opinions.

    Be very cautious renting here. My 10x20 unit started at $225/month in July 2024. Since then, Extra Space has raised it to $305, then $385, and now $433 effective 7/1/2026. That's insane! That is nearly double the original rate with no added services, no upgrades, and no meaningful explanation beyond “market conditions.” What makes this even more frustrating is that their own website currently advertises 10x20 units at this same location for a $200 web rate / $306 in-store rate, while an existing customer is being charged $433 for the same size unit. In my opinion, this is an aggressive rate-hike strategy that customers should know about before moving in. The initial rate may look reasonable online, but based on my experience, the price can increase dramatically once your belongings are already stored there. I will be vacating and would not recommend this location unless you are prepared for major rate increases after move-in. **Edit 6/1/26: You will see below that they have a standard blurb they post on negative reviews asking the customer to 'call to discuss account details'. I want to pass along that they do not negotiate the insane price hike on longer term customers, instead they point you to the contract where they have the ability to increase pricing at their will. You have been WARNED** ... Read more

    Amazing experience! I went in for a lost key and new lock replacement and as soon as I walked in, the office was clean and smelled like Christmas. The staff was extremely helpful and even had found my keys and gave them back. Once I found they were broken by being run over, they helped with finding me a replacement immediately. ... Read more

    Account manager was very helpful. Onsite personnel were friendly and helpful. Very good experience. While this was an unusual, one-time event to temporarily store my RV, I would recommend them to everyone. ... Read more

    I personally didn't have the best experience, but it was my fault. I understand that protocol must be followed. I'm leaving this review because, in the midst of my situation, Derek went above and beyond by offering genuine help, and was nice about everything, all the while knowing that my account was delinquent, and my communication was subpar at best. A very rough day I was having, and Derek put a positive twist to it. I'd like him and everyone else to know that I am very appreciative. My whole experience could have been way worse. Thank you Derek! Little things, like the way you handled this situation, go a long way. ... Read more

    Frequently Asked Questions

    The right storage unit size depends on what you plan to store and how much space you need to move around your items.
