Most guides on this topic read as if they were written for a generic storage unit in an average climate: stack boxes, use shelving, store furniture vertically. That advice is all sound, but it skips the dimension that matters most if you’re storing in Scottsdale: the environment your unit operates in, and how that changes what maximizing space actually looks like in practice.
Scottsdale summers regularly reach 115 degrees. At McDowell Mountain Community Storage, every unit is fully indoor and climate-controlled, which means your belongings are protected from the heat, regardless of what you store or how you pack them. But how you use the space inside that unit and which packing approaches work best in a facility with multiple loading docks and elevator access are worth thinking through carefully before you start moving things in. Doing it right on the first load saves you from having to rearrange everything a month later.
Start with the Right Unit Size, Not the Cheapest One
The most common storage space mistake isn’t how people pack their unit. It’s renting a unit that’s too small for what they actually have, then spending the entire rental period working around that constraint.
A unit that’s packed to the ceiling with no clear path to the back is technically “maximized,” but it’s maximized in a way that makes accessing anything in the rear impossible without moving half the unit. That’s not efficiency; it’s a recurring inconvenience that gets more frustrating every time you need something from the unit.
Before you start packing, use the space estimator to get a realistic sense of what size unit you actually need. The size guide shows what fits in each unit type, from a 5×5 to a 10×25, with specific examples of furniture combinations and room equivalents. Renting one size up from your initial estimate often costs less per month than you’d expect and eliminates the frustration of a chronically overpacked unit.
Pack Boxes to a Standard Height and Use Uniform Sizes
The single most impactful change most people can make to their packing approach is committing to uniform box sizes, particularly for boxes that will be stacked. Random box sizes create an unstable pyramid that can only go so high before it becomes unsafe, and it wastes the vertical space above every irregular item.
Medium boxes packed uniformly to their rated weight capacity stack more securely than large boxes packed light or heavy boxes that bow at the sides. Most moving supply retailers and storage facilities sell boxes in standardized sizes precisely because uniform stacking is the most efficient use of vertical space.
If you’re using our facility’s moving supplies, the team can help you identify which box sizes work best for what you’re storing. Consistent box dimensions, filled fully but not over-packed so they maintain their cube shape, will let you safely stack four to five boxes high with confidence and reach the top of a standard 8-foot unit without wasted air space between the top box and the ceiling.
Stack Heavy Items Low, Large Furniture to the Back
This principle is consistent across every storage guide for good reason: it affects both safety and accessibility. Heavy boxes and dense items should be placed on the floor or in the bottom layer of any stack. Large furniture, appliances, and bulky items that you’re unlikely to need during the storage period go to the back of the unit first.
In a multi-story facility like ours, with two elevators and multiple loading docks, this is easier to execute than in a single-story drive-up facility where you’re making choices under pressure while unloading a truck in the parking lot. Plan your layout before your first load arrives, not after the truck is half empty.
A simple sketch of your intended unit layout, drawn before moving day, is one of the most underused storage planning tools available. Label which wall the furniture goes on, where the aisle runs, and which area holds the items you’ll need to access regularly. Fifteen minutes of planning saves hours of reorganizing.
Create a Clear Aisle From Front to Back
A storage unit where everything is accessible from the front is one you’ll use. A storage unit where the thing you need is always somewhere in the middle is one you’ll dread visiting.
Leave a clear walking aisle down the center or along one wall from the front door to the back of the unit. This aisle doesn’t need to be wide; roughly two feet is enough to navigate, but it needs to run the full depth of the unit so nothing stored in the back becomes permanently inaccessible under layers of other items.
Items you need frequently go near the front, on the sides of the aisle, where you can reach them without moving anything else. Items you’re storing long-term and rarely need go to the back. This sounds obvious, but most people fill a unit from back to front and end up with the items they access most buried behind what they never use.
Use Furniture as Storage, Not Just Storage Subject Matter
Dressers, wardrobes, filing cabinets, and bookshelves take up floor space in a storage unit whether they’re empty or full. Pack them as if they’re boxes.
Dresser drawers can hold folded clothing, linens, or soft items that don’t need rigid boxes. Wardrobe boxes aren’t necessary if your wardrobe unit has a hanging rod; keep it assembled and fill the base with shoes, small items, or soft goods. Filing cabinets can hold documents, office supplies, or other small items that would otherwise need separate boxes. Bookshelves, if you’re leaving them assembled, are ready-made shelving for the unit itself.
In Scottsdale’s climate-controlled storage environment, you don’t need to worry about humidity warping wood furniture or heat degrading fabric items the way you would in a non-climate-controlled unit. Packing soft items inside furniture rather than in separate boxes is genuinely safe here, unlike in a standard outdoor drive-up unit during an Arizona summer.
Disassemble What You Can, Wrap What You Can’t
Bed frames, dining tables, sectional sofas, and large shelving units all take dramatically less floor space when disassembled. A queen bed frame that occupies eight square feet assembled leans against a wall and takes up less than a foot of depth when broken down into rails and headboard.
Store hardware for disassembled furniture in labeled zip-lock bags taped directly to the furniture pieces they belong to. This is one of those details that seems unnecessary until you’re trying to reassemble a bed frame six months from now with no memory of where the bolts went.
Items that won’t be disassembled, upholstered furniture, mattresses, electronics, mirrors, and artwork benefit from appropriate protective wrapping. Mattress bags, furniture blankets, mirror boxes, and stretch wrap are available at most moving supply outlets and at our facility. In a climate-controlled indoor unit, these materials protect against dust and surface damage rather than heat or moisture, but they’re still worth using for items you care about.
Label Every Box on Two Sides, Not Just the Top
Boxes stacked four high have labels facing the ceiling. You can’t read them without moving everything above them. Label every box on at least two visible sides, ideally the front-facing side and one adjacent side, so the contents are readable without disturbing the stack.
A simple color-coding system by room or category, a piece of colored tape or a colored marker, lets you identify which boxes belong to which category at a glance from across the unit. This matters most when you need one specific item from a unit that’s been organized for months, and the visual pattern of everything has become familiar background noise.
Take Advantage of What the Facility Offers
The practical advantages of an indoor, multi-story facility with elevator access and multiple loading docks extend beyond just the climate control. Moving appliances, heavy furniture, and large items to an upper-floor unit is genuinely manageable with elevator access, unlike in a walk-up or outdoor facility. The loading dock structure means a moving truck can unload directly at the building entrance rather than requiring you to cart items across a parking lot in summer heat.
If you’re not sure which unit size gives you the right combination of cost and space for what you’re storing, our team at McDowell Mountain Community Storage can walk you through the options and help you visualize what your specific items would look like in each size. We’re open seven days a week, and the size guide and space estimator on the site give you a useful starting point before you visit.

Frequently Asked Questions: Maximizing Space in a Storage Unit
What is the best way to stack boxes in a storage unit?
Stack heavier, denser boxes on the bottom and lighter boxes on top. Use uniform box sizes when possible for more stable stacking. Fill boxes fully, so they hold their cube shape and don’t bow or collapse under weight. Standard medium boxes stacked to their rated capacity can reach four to five boxes high safely in an 8-foot-ceiling unit, leaving minimal wasted vertical space.
Should I leave an aisle in my storage unit?
Yes. A clear walking path from the front door to the back of the unit makes every item accessible without having to move other items to reach it. Position items you access regularly near the front, along the sides of the aisle, and long-term storage items toward the back. An aisle of roughly two feet is sufficient for most units.
How do I keep my storage unit organized over time?
Labeling on two sides of every box, a simple inventory list with the unit’s contents, and a consistent system for putting items back where they came from after accessing them are the habits that keep a unit organized over months or years. Take a photo of the unit layout after your initial setup as a reference for future visits.
Does climate control change how I should pack my storage unit?
Yes, in some ways. In a climate-controlled, fully indoor unit like those at McDowell Mountain Community Storage, you don’t need to account for moisture-wicking packaging or heat-resistant materials the way you would in a standard outdoor unit in an Arizona summer. Soft goods can be packed inside furniture drawers without risk of mildew. Electronics don’t need extra heat protection. What you still want to protect against is dust accumulation over time, which appropriate coverings and sealed boxes address.
What size storage unit do I need to store the contents of a one-bedroom apartment?
A 10×10 unit is the standard recommendation for a one-bedroom apartment with standard furniture, boxes, and appliances. If you have oversized furniture, a sectional sofa, a king bed, or multiple large appliances, a 10×15 gives you more working room and aisle space.
