The units are clean and well-maintained, both inside and outside, and moving equipment is available at every building. I've also noticed that Michelle and Alma are always willing to help -- they answer the phone during operating hours (except when assisting customers on-site) and respond to emails promptly. I truly appreciate their outstanding service. I've been with Mount Diablo Storage for many years, and I love this place. Pam

They were charging me monthly on an old discontinued AMEX credit card which was never updated and allowed by AMEX, until I called and questioned the old card vs my new card!

Everyone I interacted with by phone, email, and in person was friendly, helpful, and knowledgeable. One of the employees even helped me move a table and heavy box that I couldn't lift myself after the movers left. I started with a 10x10 unit and moved into a smaller one a year later because they were going to charge $312/mo starting 4/30/2026 (started at $150 or $160/mo for 6 months, then rate increased to $200-something/mo). My new unit was $189/mo and I didn't have to deal with rent increases because I recently cleared out my unit after 3 months. The space is very safe and secure, requiring a code to enter and exit the gate. Also love the free coffee and tea. I'm happy to not have to pay for the unit anymore but would recommend to anyone considering storage space.

The place is clean, usually has enough carts, has a convenient bathroom, and my stuff hasn't been taken. Today I get there at 6:05 pm, and there is this sign on the gate. So I can't get in. The office is closed - apparently it closed very promptly at 6. I could have been there earlier if I had known - like if they had sent an email informing me of this rather significant change. They clearly have my email, as they keep sending me emails telling me the rent is going up. But no, I had to drive there and home for nothing. Not happy.

I've been renting here for years, and the access-hour issue has become unacceptable. The property…read moreadvertises access from 6 AM to 10 PM, yet for the past few months tenants have been told they need to leave when the office closes at 6 PM and that access is only during office hours. If access hours are being changed, that needs to be formally communicated and updated everywhere it's advertised -- not handled verbally by staff or by a piece of paper taped to the gate keypad. There have also been repeated issues with the on-site manager, Dana. I personally had a problem regarding my service animal when she instantly yelled at me that dogs were not allowed on the property and would not listen to anything I had to say. I ended up leaving and contacting the district manager, who clearly told me that service animals are allowed on the property as long as they are leashed and said he would speak with her. Dana had also put up "no animals in the building" signs, which mysteriously disappeared the day after I contacted the district manager. Lastly, I've had two rent increases within one year and am currently paying around $280 ($300 with late fees), despite requesting multiple times to move my payment due date to better match my pay schedule and being ignored. Meanwhile, the exact same size units online are listed between roughly $108-$170. I've been at this facility for over three years and have watched it steadily decline. At this point, management either needs to honor the 6 AM-10 PM access customers are paying for or clearly update the policy.
