The staff here is absolutely incredible — especially Tatiana, Racheal, Chivon, and Rosa. While the prices are a bit higher, I gladly pay them because the level of security and peace of mind they provide is worth it. They truly make you feel like family, not just a customer. The office itself is very welcoming, with plants of different kinds that give the space a warm, reassuring feel.

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

This particular storage facility provides self storage units of different sizes, ranging from 50 to 210 square feet. Space is not an issue! If you have more belongings to store, or simply bulkier items or even vehicles, you should go for larger storage units.

You already know how much stuff you need to put in self storage, so figuring out the unit size you need is the next step. Smaller units such as 5'x5' or 5'x10' spaces can usually be filled with the amount of items you would normally store in a closet: a few chairs and lamps, sports equipment, garden tools and some boxes.

Moving on to larger sizes, imagine the 10'x10' and 10'x15' units as similar to a bedroom or a living room – larger pieces of furniture, sturdier equipment and bicycles can fit here. Finally, a 10'x20' unit has enough space for the contents of a 3-bedroom house, while the larger 10'x30' space easily accommodates the contents of a loaded semi-truck.

Accessibility and quickness are key when it comes to storage, so drive-up storage units are generally regarded as very convenient. Pull your car right up to your storage space, load, unload, and you're good to go! However, if you're mostly storing temperature-sensitive items, you should rather consider indoor storage units.

Climate-controlled units maintain consistent temperatures and humidity levels all year round, making them perfect for all your sensitive items. Moisture and varying temperatures can damage a whole host of things, and that is why a lot of people choose to use climate-controlled units to store items like wooden furniture, electronics, artwork, documents and photographs, collectibles, antiques, etc. If the belongings you're storing are important to you, you should consider renting a climate-controlled unit.
