The Ultimate Self Storage Guide

Self Storage 101: Your Everything Guide to Self Storage

If you’ve found yourself reading this self storage guide, this is more than likely your first experience in needing a storage unit. Welcome. Self-storage isn’t just about stashing your stuff away in a box and forgetting it exists. Nope, it’s a world filled with choices, opportunities, and yes, a bit of strategy—all wrapped up in the glorious promise of reclaiming your personal space. This guide will help you do just that – reclaim your personal space in the smartest way possible, and provide you with answers to all of the questions you may have about storage.

Why Would You Need A Storage Unit

Moving

Moving of any kind is a giant task, and a bit more manageable with a solid moving checklist. An integral part of that is a storage unit. A storage unit can be a lifesaver in a variety of situations. For starters, moving houses often tops the list of reasons people turn to self-storage. A storage unit is great for downsizing, so you’re not overwhelmed with boxes. Buying and selling a house isn’t always one-to-one transaction. There are many scenarios where you must wait for your new place to be ready. Again a storage unit can be a great tool for those situations. Ultimately, when it comes to moving, a storage unit can give you the breathing room you need to stay organized.

Moving out of state? That’s another big one. Relocations, especially cross-country ones, can come with their unknowns.. A storage unit provides a secure spot for your belongings while you sort out the logistics of your new home. And let’s not forget college students. Dorm rooms are tiny, and when it’s time to head home for the summer, there’s usually no space to bring everything back. Stashing your mini-fridge, extra bedding, and textbooks in a local storage unit is a practical solution.

Decluttering

Then there are the everyday scenarios. Maybe you’re looking to declutter your house and need extra space for seasonal items like holiday decorations or winter coats. Or perhaps you’ve got some serious hobbies—think kayaks, mountain bikes, or even ATVs—and no room to keep them at home. Storage units are also ideal for seasonal equipment and tools safe and out of the way during the off-season.

Remodeling

Home remodeling and home improvement is another common reason people seek out storage. If you’ve never done a remodeling project before, you’ve probably underestimated the amount of mess it causes. And all of those belongings or items in that room must go somewhere else. That takes away valuable room in another area of your home. A storage unit helps you avoid all of this hassle. It keeps your belongings from getting dirty and dusty from the debris, and frees up the rest of your place while you remodel. 

Whatever your reason, storage units offer flexibility and peace of mind. By providing a secure, accessible space for your belongings, they let you focus on the task at hand—whether that’s settling into a new home, remodeling your bathroom, or simply enjoying a little extra elbow room at home.

The Cost of a Storage Unit

How Much Does a Storage Unit Cost?

Pricing can vary depending on factors like size, location, and the type of storage unit.
A small unit such as a 5×5 may cost anywhere from $22 to $55 a month, depending on location and unit type. A 10×10 may by anywhere between $55 and $115 a month. A 10X20 unit can cost anywhere between $115 and over $200 a month. And if you’re eyeing a space big enough to fit a small army’s worth of belongings (or a car) you’re looking at something bigger than a 10×20 unit which generally costs $200 or more per month.

What Affects the Price?

First off, location matters. Storage units in bustling urban centers will cost more than those in quieter, suburban areas. Add climate control into the mix—rentals that keep your items safe from wild weather swings—and you’ll see an uptick in cost. Accessibility is another factor; drive-up units or ground-level ones might come with a convenience surcharge. Don’t forget to check for promotions—many facilities, such as National Storage provide discounts for new customers or long-term rentals.

Storage Unit Sizes

You quickly realize that storage units are not one-size-fits all. It’s important to get the correct size storage unit so you don’t overpay for space you don’t need. Here’s how storage unit sizing  breaks down below.

Small Units

You might be asking, what can fit in a 5×5 storage unit? Imagine a unit the size of your hall closet – that’s essentially a 5×5 unit. A 5×5 unit is about 25 sq. ft. A 5×5 rental is ideal for those boxes of seasonal decorations, a few bins of memorabilia, and maybe even an old treadmill you’re totally going to use again one day.  A 5×5 unit is also a great choice if your garage or attic is overflowing with bins of photo albums, or hobby supplies. College students often use these smaller units to stash dorm essentials such as bedding, mini-fridges, and textbooks during the summer break.

A step up is a 5×10 unit, or about 50 sq. ft. of storage space. This space is ideal for storing the contents of a small room, such as a few pieces of furniture, boxes, or seasonal items. This unit size is popular for people who are storing items during a home renovation or decluttering a room in the house that was being used for storage. It’s also a great size for those with hobbies that come with a lot of gear—think kayaks, golf clubs, or camping equipment.

However, if you find yourself needing to store larger furniture, multiple appliances, or the full contents of a one-bedroom apartment, it’s time to consider upgrading to a medium-sized unit. This will give you the extra room needed to avoid cramming and keep your items accessible and well-organized.

Medium Units

One of the most common medium sized units is a 10×10, which is roughly 100 sq. ft. For those asking, what can I fit in a 10×10 storage unit? This unit is roughly the size of a small bedroom and can fit the contents of a one-bedroom apartment – furniture, appliances, and all.

One of the most common reasons people use medium storage units, like a 10×10 is for moving, especially those transitioning from a one-bedroom apartment to another apartment or home since a 10×10 unit can comfortably hold the contents of one-bedroom’s worth of furniture, appliances, and boxes.

Medium units like a 10×10 are also a popular choice for people looking to store seasonal or recreational items. Think camping gear, kayaks, or skis that don’t see daily use but need a safe, out-of-the-way place. They’re also great for storing larger collections of tools, lawn equipment, or outdoor furniture during off-seasons.

A 10×15 unit adds more depth, making it ideal for larger items or increased quantities. These units are often chosen when a small unit (5×10)  simply won’t cut it but a large unit (10X20) feels like overkill. 

A 10×15 is about 150 square feet. One of these rental units can handle the bulk of a two-bedroom apartment, including larger items like dining sets and oversized couches. For bigger projects involving multiple rooms like a kitchen and dining room renovation, a 10×15 unit ensures that all your furniture and belongings remain protected from dust and damage.

Large Units

A 10×20 is over 200 square feet. These rentals can store the contents of a three-bedroom house or a standard car. A 10×30 unit is over 300 square feet, and like having a private warehouse, perfect for large households or even small business inventory.

Common Items Stored in Large Units

Large storage units, such as 10×20, 10×30, or even larger sizes, are a practical solution for accommodating substantial amounts of belongings. These units are spacious enough to handle the contents of a multi-bedroom home, making them ideal for moving the family from one house to another. People often choose large units when they have an entire household to store, including big furniture pieces like sectional sofas, dining room sets, and king-sized beds. Appliances such as refrigerators, washers, and dryers also fit comfortably, along with multiple boxes of household goods. 

While many of the household items, like chairs and desks, you can place in your storage unit without a second thought, some items require some additional how-to when it comes to storage, such as storing appliances like washers, dryers, and other appliances. So keep that in mind as you’re moving things into storage.

Another common reason for renting a large unit is vehicle storage. A 10×20 unit can typically house a standard car, while larger spaces can accommodate trucks, boats, trailers, or recreational vehicles (RVs). This makes large units an excellent choice for people who need secure, weather-protected storage for their vehicles, especially during off-seasons or long-term travel. We take a comprehensive look at vehicle storage later in this guide.

Businesses often utilize large storage units for inventory overflow, equipment, or office furniture. Contractors, for example, may store tools, building materials, and supplies in these units, benefiting from the space to organize and access their items efficiently. Retail businesses also use large units to stock seasonal inventory, ensuring they have room to operate without overcrowding their stores or warehouses. We cover business storage in another section later in this guide.

Picking the Right Size Rental Unit

Start by taking inventory of what you need to store. Don’t forget to think vertically – stacking boxes can save a ton of space. And if you’re still unsure, our size guide can help you visualize your options.

Types of Storage Units

Storage units come in many types, each designed to meet a variety of needs and situations. In the following sections, we’ll explore the different types of storage units in detail, helping you understand what makes each one unique and how to choose the right option for your specific requirements.

Traditional Self-Storage (non-climate controlled) 

Non-climate-controlled storage units are the most traditional and economical option when it comes to self-storage. These units are perfect for storing items that are less sensitive to fluctuations in temperature and humidity, making them an affordable and practical solution for many people. 

Drive-Up Storage Units

Some of the common terminology you’ll see when you’re looking at traditional self storage is “drive-up” or “ground-level.” These allow you to access your belongings directly from your vehicle, making loading and unloading easy.

Drive-up storage units are especially convenient for those storing heavy or bulky items. With ground-level access, you can back your car, truck, or moving van right up to the unit, reducing the physical strain of moving large items. This setup is ideal for contractors or businesses storing tools, construction materials, or equipment they need to access frequently. On the other hand, indoor non-climate-controlled units—often located in larger storage buildings—provide an extra layer of security and are less exposed to outdoor dirt or debris.

What Can You Store in a Non-Climate Controlled Storage Unit?

So, what kind of items can you store in a non-climate-controlled unit? These units are great for things like outdoor equipment, gardening tools, patio furniture, and seasonal decorations. Items like plastic bins of clothing, books, or durable household goods also fare well if they’re properly packed and protected. People often choose these units for short-term needs, such as during a move or renovation, when items are not being stored long enough to be affected by environmental conditions.

While non-climate-controlled units are practical and cost-effective, it’s essential to pack your items carefully. Use heavy-duty plastic bins to keep moisture at bay, and consider placing pallets on the floor to prevent items from sitting directly on concrete, which can get damp. For added protection, use desiccants or moisture-absorbing packets in your storage boxes. With these precautions, non-climate-controlled units can effectively meet your storage needs without breaking the bank.

It’s worth nothing that it may seem like you can put just about anything in a storage unit. That certainly isn’t the case. Sure, storage can be a safe haven for most things, but also check out what things you should not put in a self storage unit, to ensure your belongings stay safe and protected. 

Climate-Controlled Storage

When it comes to self-storage, climate-controlled units are the gold standard for keeping your belongings safe from the unpredictable whims of Mother Nature. These units maintain a consistent temperature and humidity level year-round, which is crucial if you’re storing anything sensitive to extreme conditions.

So, when should you choose climate-controlled storage? The answer lies in the nature of your items and the climate where you live. If you’re in a region with significant temperature swings – think sweltering summers, freezing winters, or high humidity – a climate-controlled unit is a smart investment. Wooden furniture, for instance, can warp or crack when exposed to fluctuating conditions. Electronics are another prime candidate for these units, as high humidity can cause corrosion, while extreme heat might fry delicate components. Artwork, photographs, and family heirlooms also benefit greatly from the stable environment, ensuring that your cherished items remain in pristine condition over time.

What can and should be stored in climate-controlled storage? Besides the aforementioned items, also consider using these units for musical instruments, vinyl records, important documents, leather goods, and even clothing – especially if you’re storing something like a wedding dress or vintage apparel. Basically, anything you’d be upset to find damaged after a few months in storage should go in a climate-controlled space.

Of course, this level of protection comes at a price. On average, climate-controlled units cost about 25-50% more than standard storage options. When you’re storing valuable or sentimental items, the added cost is a small price to pay to avoid the heartbreak of damage caused by heat, cold, or moisture. Think of it as insurance against the elements – a little more upfront to save a lot down the line.

Vehicle Storage

Before we dive into the details, let’s take a moment to spotlight one of the most popular uses for self-storage: vehicle storage. Here we explore all the ins and outs of vehicle storage, including how to pick the right size and type of unit, what’s involved in preparing your vehicle for storage, and the perks of indoor versus outdoor options. From compact cars to massive RVs, we’ll cover the unique needs of different types of vehicles and offer practical tips to ensure they stay in top condition while stored.

Cars

Car storage might seem like an unnecessary luxury, but there are plenty of reasons to consider it. Reasons for car storage include: 

• Heading out of town for an extended period
• You have an extra vehicle you don’t use often 
• Free up garage or driveway space

Whatever the reason may be, indoor car storage offers unbeatable protection from weather, theft, and vandalism, making it ideal for high-value or classic vehicles. On the other hand, outdoor parking spaces are a cost-effective solution for less expensive cars or when short-term storage is all you need.

Preparing your car to be stored is a smart idea before you leave your car unattended in storage. Start by giving your vehicle a thorough cleaning inside and out. Dirt and grime can damage the paint and upholstery over time, so this step is essential for long-term storage. Next, check all fluids – oil, coolant, and brake fluid – and top them off as needed. Add a fuel stabilizer to the gas tank to prevent the fuel from breaking down, and consider disconnecting the battery to avoid drainage. Inflate the tires to their recommended pressure to prevent flat spots, and cover the car with a high-quality cover, even if it’s stored indoors, for an extra layer of protection.

Retrieving your car from storage requires its own checklist.  First, check for any signs of pests, leaks, or damage. Reconnect the battery if it was disconnected, and inspect the fluid levels again to ensure everything is in working order. Start the car and let it idle for a few minutes to get the engine warmed up and the fluids circulating. Finally, take it for a slow test drive to ensure the brakes, tires, and other systems are functioning properly before hitting the road for real. With these steps, your car will come out of storage in as good a condition as it went in.

Tire Storage

Many people will have an additional set of tires for their car for various seasons. When winter comes, it’s time to take off the all-season tires and put on dedicated snow tires, so on and so forth. But when tires are stored, they can be susceptible to cracking, flat spots, or even dry rot if not stored correctly. Thankfully you can prevent dry rot, and other common tire ailments while in storage with a little knowhow. 

Before storing your tires, start by cleaning them thoroughly. Use soap and water to remove dirt, grime, and brake dust, as these can degrade the rubber over time. Once clean, ensure they’re completely dry to avoid moisture buildup, which can encourage mold or mildew. If the tires are still mounted on wheels, consider deflating them slightly to reduce stress on the rubber and rims during storage.

For optimal storage, keep your tires in a cool, dry place away from direct sunlight, as UV rays can weaken the rubber. Storing them indoors is ideal, and if possible, use a tire rack to keep them off the ground and maintain their shape. If a rack isn’t available, stack them flat, but avoid placing heavy items on top to prevent distortion. For long-term storage, consider using tire storage bags or plastic sheeting to create a barrier against dust and humidity. It’s also wise to rotate the position of your stacked tires periodically to minimize flat spots. 

Motorcycles

Storing a motorcycle might seem straightforward, but there are important details to ensure it stays in top condition during its time in storage. A 5×10 or 10×10 unit is typically sufficient for most motorcycles, providing ample room for the bike itself along with any accessories or gear. However, choosing the right storage environment is only the first step.

Before placing your motorcycle into a unit, you should first prepare your motorcycle for storage. We’re going to sound like a broken record here, but it starts by cleaning the bike to remove dirt, grease, and road grime, as these can corrode the paint and metal over time. Once cleaned, apply a layer of wax to protect the exterior surfaces. Next, fill the fuel tank and add a fuel stabilizer to prevent the gas from breaking down, which could cause damage to the fuel system. Don’t forget to change the oil and replace the filter to remove contaminants that could degrade the engine components while in storage.

To protect the battery, disconnect it and store it separately in a cool, dry place. If you can, it is best to keep it off the ground, so it doesn’t freeze. That being said, you can leave it connected to the bike, but if you are going to store it for a long period, it’s smart to attach a trickle charger to the battery to prevent it from going dead over the long storage period. 

You’ll also want to elevate the bike or use a paddock stand to prevent flat spots from forming on the tires. Finally, covering your motorcycle with a breathable cover will help prevent moisture build-up and add a final level of protection.

When it’s time to take your motorcycle out of storage, give it a thorough inspection. Check fluid levels, reconnect the battery, and ensure the tires are properly inflated. Take a few minutes to start the engine and let it run to circulate oil through the system. 

Boats

Boat storage comes in two main varieties: indoor and outdoor, each with its own perks and considerations.

Indoor boat storage provides maximum protection for a watercraft. These spaces shield your boat from weather, pests, and even theft. Indoor storage is typically found in large warehouses or specialized storage facilities. You typically need a 10×20 or larger unit to fit a boat (of course, this all depends on the size of your boat), and as we discussed earlier, larger units tend to be more pricey.

Outdoor storage (often referred to as boat parking) on the other hand, is more budget-friendly and widely available. While your boat is exposed to the elements, many facilities offer covered options to mitigate some weather-related risks. This type of storage works well for short-term needs or in regions with milder climates. However, before you store our boat inside or outside, you should, like with other motorized vehicles, prepare it for storage.

Preparing your boat for storage, regardless of the type, is smart for the longevity of the machine. Start by thoroughly cleaning and drying the exterior to prevent dirt and moisture from causing long-term issues. Next, drain all water from the engine, bilge, and plumbing systems to prevent freezing and cracking during colder months. Adding fuel stabilizer to the tank and running the engine for a few minutes will protect the fuel system, while applying a protective wax coating to the hull keeps it looking pristine. Don’t forget to remove any electronics and valuables from the boat, and if you’re storing outdoors, consider shrink-wrapping it for an added layer of protection against weather and debris. And when it is time to get your boat summer ready, make sure you check the boat battery, check all fluids and ensure that your boat and trailer are still properly registered.

RVs & Trailers

A standard RV typically requires a space at least 12×30 or larger, depending on its length. Outdoor spaces are suitable for most trailers and RVs, but if you’re storing in a region with harsh winters or extreme heat, a covered or indoor storage option can provide added protection. Look for facilities that offer power hookups to maintain your batteries and keep essential systems operational if needed.

Preparing your RV or trailer for storage requires attention to detail to ensure it stays in excellent condition while not in use. Whether you’re storing it for the winter or during long gaps between road trips, taking a few key steps will help you avoid costly damage and keep it ready for your next adventure.

First, thoroughly clean both the interior and exterior of your RV or trailer. Remove all food to prevent attracting pests, vacuum and dust the interior, and wash the exterior to remove dirt, grime, and road salt that could corrode surfaces over time. Consider applying a protective wax coating to the exterior to shield it from the elements. A thorough cleaning can do wonders to prevent future problems.

Next, focus on maintenance tasks. Drain all water systems, including the fresh water tank, gray and black water tanks, and water heater. This prevents freezing and cracking during colder months. Add RV antifreeze to the plumbing system if necessary. Check and top off all fluids, including engine oil, brake fluid, and coolant, and ensure that your tires are inflated to the manufacturer’s recommended pressure to prevent flat spots during long-term storage.

Business Storage

Running out of office space can be a challenge for many businesses, and this is where business storage comes into play. Business storage refers to the use of self-storage units by companies to manage inventory, equipment, tools, or documents in a secure and organized manner. This can accommodate a variety of business types, from retail stores and contractors to freelancers and small offices.

Retail businesses often use storage units to handle inventory overflow, particularly during peak seasons. A medium-sized unit like a 10×15 can hold extra stock, display materials, or promotional items, ensuring the store remains uncluttered and functional. Contractors, on the other hand, benefit from larger drive-up units, which are perfect for storing tools, building materials, and equipment. These units provide easy access, allowing contractors to load and unload items quickly as they move between job sites.

Storing tools requires some additional considerations to ensure longevity. To store tools properly, as you might come to imagine, it starts with cleaning and drying all tools before storage to prevent rust or corrosion. Using pegboards can also help keep your tools accessible and organized. Power tools should have their batteries removed to avoid leaks or drainage. Placing silica gel packets in toolboxes or containers can help absorb excess moisture. 

Document storage is another common use for business storage. Law firms, accountants, and other professionals with large quantities of sensitive paperwork often opt for climate-controlled units. These units ensure important files are safe from moisture, temperature fluctuations, and pests. There’s also an additional aspect of security with storing your documents inside a storage facility. Finally, properly storing documents involves using sturdy filing cabinets or archival boxes and organizing them systematically for easy retrieval.

Wine Storage

Wine storage is a specialization only offered by some facilities. Dedicated wine storage facilities provide an ideal environment for your collection. Wine storage units are equipped with precise temperature and humidity controls, critical for preserving the quality and flavor of your wines over time. 

Different types of wine have varying temperature and humidity needs, though most thrive at around 55°F with a humidity level of 60-70%. Red wines, for instance, benefit from a slightly higher temperature range than whites or sparkling wines. Having these specific conditions maintained in a climate-controlled unit minimizes the risk of corks drying out, labels peeling, or wines becoming “cooked” due to excessive heat.

Can You Live in a Storage Unit?

Here’s the deal: no, you cannot live in a storage unit. Besides being illegal, it’s also wildly unsafe. Storage units lack essential amenities like running water, electricity, and proper ventilation, not to mention they’re just not designed for human habitation. Stick to using them for their intended purpose, and leave the living arrangements to actual housing.

How to Properly Pack and Use a Storage Unit

Packing a storage unit is like playing a life-sized game of Jenga. Get it right, and everything fits perfectly. Pack incorrectly, and you’re dodging falling boxes every time you open the door.

Packing Like a Pro

First, invest in sturdy, uniform boxes—they’re easier to stack and won’t cave in under pressure. Wrap fragile items in bubble wrap or blankets, and disassemble larger furniture to save space. Label everything clearly, because future-you will thank past-you when it’s time to retrieve that random blender.

Organizing for Access

Create aisles within your storage unit to ensure easy access to all your belongings. Instead of stacking items haphazardly, think of your unit like a miniature warehouse where everything has its place. By leaving a clear pathway down the center, you can reach items in the back without having to dismantle stacks or move heavy boxes unnecessarily.

Store frequently used items near the front of the unit so you can grab them without digging through the entire space. For instance, keep seasonal decorations or tools for occasional projects easily accessible. When stacking boxes, place heavier ones at the bottom to create a stable foundation, and lighter or fragile items on top to avoid damage. Using clear, labeled bins instead of opaque boxes can make finding specific items much simpler.

Shelving units are a game-changer for long-term storage. Vertical storage maximizes your space while keeping items organized and off the ground, which can also protect them from potential water damage. Group similar items together, like tools on one shelf, kitchenware on another, to streamline your inventory.

Finally, create a simple map or inventory list of your unit’s contents. This will save time and reduce frustration when you’re searching for specific items. Knowing how to pack your storage unit will make your life immeasurably less frustrating when it comes time to access the contents of your storage unit later. 

Maintenance

A well-maintained unit doesn’t just protect your items; it also ensures you’re getting the most value out of your rental.

Start by ensuring the unit is thoroughly cleaned before you move anything in. Sweep out any debris, check for moisture or leaks, and wipe down surfaces if necessary. Using plastic bins instead of cardboard boxes can help keep your items better protected from pests and humidity. For an added layer of security, elevate boxes and furniture on wooden pallets to improve airflow and prevent water damage in case of minor flooding.

To keep insects and rodents like mice out of your storage unit, avoid storing food or anything with strong scents. Use airtight containers for any items that might have an odor. Adding natural repellents like cedar blocks or sachets of lavender can help deter bugs. For rodents, place traps or bait stations around the unit, especially near entry points, and seal any visible gaps or cracks in the walls or doors.

Visit your unit periodically to inspect for signs of pest activity, such as droppings, gnawed materials, or spiderwebs. Keep the area tidy by organizing items to avoid cluttered corners where pests might nest. If you notice any issues, alert the storage facility management right away so they can address the problem before it escalates.

Amenities to Expect at Storage Facilities

Storage facilities have stepped up their game in recent years. Here’s what to look for:

Accessibility

As previously discussed, drive-up units make loading and unloading a much simpler task. Beyond that,  24/7 access ensures you can grab your items whenever you need them.  Also, look for storage facilities with wide lanes especially for maneuverability regarding trucks and trailers.

Security

Modern facilities are like mini fortresses, designed with security as a top priority. Gated entries ensure that only authorized individuals can access the premises. Surveillance cameras monitor activity around the clock, deterring theft and ensuring that any incidents are recorded for investigation if needed. Also, look for a facility that offers high-quality locks, often paired with which can make it extremely difficult for unauthorized access to occur.

Some facilities take security even further by offering individual unit alarms. These alarms are triggered if someone tampers with the lock or door, providing an immediate alert to the facility’s management.

Extras

Many facilities offer perks like moving truck rentals, packing supplies, and even mailing services. These extras can save you time and effort during a move.

Insurance and Storage Units

Insurance might not be the most exciting topic, but it’s an important one. If you’re asking, can i rent a storage unit without insurance, the answer is most likely, no. Most facilities require proof of insurance, and your homeowners’ or renters’ policy might already cover stored items. If not, tenant protection plans are usually available.

Insurance provides peace of mind by covering theft, water damage, fire, and more. It’s a small investment for the security of your belongings and can save you a lot of headaches down the line. 

Self-storage doesn’t have to be complicated. With the right preparation and a solid understanding of your options, you can make the most of your storage experience. Ready to declutter your life?
