Stephen K. - 3 June 2025
I was pleaseantly amazed at the affordable pricing,(Dependant on your actual needs, [of course]) and I'm a cheapskate. My advise, don't rent more space than you need, Stack them boxes high, and save a few bucks. Also, If you won't need floor level, get an upper. It's probably cheaper. WARNING: NO SMOKING. You can be cited or banned. DO NOT leave your bulk trash tossed at the dumpsters, the managers really hate that. Besides, dumpsters are usually padlocked. So either ask them nicely, or, since your moving truck usually has SOME space left, toss it at a WALLMART or something. I heard they will pinpoint the litter-er, and cite them, from the unit number they left from (account holder). TYPICALLY: Office is open until 6:00PM Mon-Sat. Gates: Until about 10:00PM (with access code of course). Sunday is variable, from site to site. Hours may vary, slightly. Check ahead of time. ... Read more

This particular storage facility provides self storage units of different sizes, ranging from 25 to 400 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.

Monthly prices for units offered by Extra Space Storage - 850 South Mount Vernon Avenue start from $41 and can go up to $286 for larger spaces.

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.
