We really needed this unit because our garage was overflowing with supplies and belongings we weren’t ready to part with. Since we’ve been here, Tatiana has been a tremendous help in finding us the perfect ground-floor unit for storage. Her customer service and work ethic are outstanding! The storage facility is very clean, and there’s no trash lying around. The rate was unbeatable. Later, we even had to upgrade to a larger unit, and the rate for that one was just as great. Highly recommend ... Read more

Security Public Storage. I originally went there to Rent a U-Haul because I have rented storage space from them in the past and they were really easy to talk to and eager to help. This time I needed a space in an emergency situation and it was as easy as ??!! Tatiana was still an employee and had everything ready when I got back to the facility. I loaded up returned the van and can relax knowing they have my best interest at heart. I won't ever go anywhere else. I wish I could take them to Arizona with me. ... Read more

These amenities include Climate-Controlled, Indoor, Drive-Up Access, Retail Available, Onsite Manager, Truck Rentals, Contactless Renting, Security Camera, Gate, Credit Cards Accepted, Elevators, First Floor Access, Multi-Level Storage and Online Payment. Most of these amenities can prove to be very useful depending on what you need to store. For example, climate-controlled units can come in handy for keeping sensitive items, drive-up access can make your loading and unloading process easier, and extra security measures will ensure your items are kept safe at all times.

The storage units offered by Security Public Storage - 521 Harbor Court can satisfy all of your storage needs. Different sizes here range from 25 to 210 square feet. You can go for smaller units if you don't have a lot of items to store, while choosing a larger space is recommended in case you need to store a lot of furniture, bigger items or even vehicles.

The unit size that you should choose obviously depends on how much stuff you need to store. On the one hand, you should think of smaller units (5'x5' or 5'x10') as closets – they can be used to store chairs, lamps, moving boxes and sports equipment, along with smaller pieces of furniture, books and documents.

On the other hand, the 10'x10' and 10'x15' spaces are good for storing larger items of furniture, bicycles and a larger number of possessions. If you need even more space, then 10'x20' and 10'x30' units can easily accommodate the contents of an entire 3- or 4-bedroom house.

Storage units offered by Security Public Storage - 521 Harbor Court come at a variety of prices, starting from $133 per month for typically smaller units. However, larger spaces can set you back up to $409 a month.

We know that when it comes to self storage, there is nothing more important than quickness and accessibility. Drive-up access is an extremely convenient amenity, as you can park your vehicle right next to your unit, making it significantly easier to load and unload the items you will use storage for. However, drive-up storage units tend to be outdoors, so you might consider indoor storage spaces with climate control if you're looking to keep temperature-sensitive items in peak condition.

Yes, you might, depending on what you need to put in storage. Climate-controlled spaces keep temperatures and humidity levels consistent all the time, which means they are perfect for storing sensitive items. Seeing that a whole host of things can be damaged by varying temperatures and excessive moisture, many people choose to rent climate-controlled units for personal items such as documents, photographs, paintings, collectibles, electronics, wooden furniture, antiques and even vehicles. If you're looking to store such items that are valuable to you, consider renting a climate-controlled unit!
