Apartment living offers numerous advantages, including prime locations, cozy layouts, vibrant communities, and affordability. But let’s be honest: storage space isn’t one of them. From holiday decorations to bulky furniture, your belongings can quickly overwhelm your living space. The solution? Finding extra space with an apartment storage unit.


At a Glance: Best Storage Units for Apartments

This guide will help you choose the perfect storage size, ensuring you’re not overpaying for space you don’t need or cramming everything into a tight space.


Why Consider an Apartment Storage Unit?

The Problem: Limited Space in Your Apartment

Closets fill up. Boxes pile high. You start tripping over bikes, seasonal bins, or furniture that just doesn’t fit. Suddenly, your home feels more like a warehouse than a sanctuary.

The Solution? External Storage

A storage unit is like an extra room you rent. Move nonessential items out of your apartment and free up your space, without paying for a bigger lease.

Do I Really Need a Storage Unit if I Live in an Apartment?

Yes, an extra storage solution will help if you’re short on space or rotating items seasonally. They’re also great if you do not have vehicle storage at your complex! Even a small storage option, such as a 5x5, can hold off-season clothing, sports gear, or boxes that would otherwise clutter your living room.


What Factors Influence the Ideal Storage Unit Size?

When selecting an apartment storage unit, begin by determining the number and type of items you’ll be storing. And then consider your access requirements. Identifying this ahead of time will ensure you have plenty of space.

Quantity of Items

  • Just a few boxes of personal items? → smaller unit.

  • Entire apartment move → medium or large unit.

Types of Items

  • Small & medium-sized boxes stack easily → smaller unit.

  • Furniture, mattresses, and appliances eat up floor space fast. → medium or large unit.

  • Vehicle, motorcycle, or boat? → large or extra-large unit.

Need for Access

  • Frequent Visits? Choose a slightly larger unit for aisle space or drive-up storage unit.
  • Long-term storage? Pack tighter in a smaller space.

Remember, ceilings are usually tall in storage units (approximately 8 feet+). By stacking boxes vertically, you can choose a smaller unit.

Apartment Storage Unit Considerations: Climate, Access & Security

There are other factors to consider when selecting the right storage unit for your apartment. A few things to think about?

Climate Control

When To Choose It:

  • Storing wood and leather furniture, electronics, artwork, or clothing.
  • Living in an area with extreme heat, cold, or humidity.

When You Can Skip It:

  • Storing tools, plastic bins, outdoor gear, patio furniture, or short-term items.

Access & Convenient

  • Location: Storage locations near you will mean shorter trips.
  • Hours: Do you need 24/7 access or standard hours, such as 6:00 AM to 10:00 PM?
  • Drive-Up Storage Units: Easily load and unload directly from your car. A necessity if you need vehicle storage.

Business Storage Needs

If you're working from home, you should consider whether you need storage for business inventory or other office supplies. If you're running a small service-based business out of your apartment, such as painting or landscaping, you may need a large unit, such as a 10x30 storage unit

Security

Self-storage facility security features to look for include:

FAQ: Are Climate-Controlled Storage Units Worth the Cost?

Yes, if you're storing sensitive items, such as furniture, electronics, and documents. For plastic totes, tools, or short-term storage, you may not need it.


Vehicle Storage and Outdoor Parking for Apartment Residents

If your apartment complex doesn't offer garage space or has limited parking, a storage facility can be a suitable solution. This will help you find a place to store your outdoor gear, vehicles, and other belongings.

Why Consider Vehicle Storage?

  • Cars and Trucks: A 10x20 unit (one-car garage equivalent) can protect your vehicle from weather or theft.
  • Motorcycles or Scooters: Even a 5x10 works for one or two bikes, with room for helmets and gear.
  • Bicycles: If your apartment lacks a bike room or bike rack, a 5x5 unit will keep them safe and out of your living room or entryway.
  • Seasonal Vehicles: Store boats, jet skis, or ATVs when not in use. Without a garage at your apartment complex, you'll be unable to store them on-site.

FAQ: Can I Store a Vehicle in an Apartment Storage Unit?

Yes! Many facilities offer drive-up units or designated vehicle storage options. Always confirm requirements, such as proof of registration and insurance.


Apartment Storage Unit Cost & Budget Tips

Storage units are an additional monthly cost that you'll need to think about; however, the cost of a self-storage unit is less expensive that moving into a larger apartment. You'll get extra space at a better price! 

Before you rent a storage unit:

  • Compare Facilities: Prices can vary widely.
  • Check Promotions: Many storage facilities offer "First Month Rent Only $1" or "50% Off 3 Months"
  • Check Web Rates: Many storage facilities offer discounted rates if you rent or reserve your unit online.
  • Ask About Fees: There may be additional one-time or monthly fees, including an admin fee, insurance, or late fees.

Quick Step-by-Step: Choosing Your Apartment Storage Unit

Here's a quick list of the five steps you want to take when selecting your self-storage unit:

  1. Inventory your items. List furniture, boxes, and appliances.

  2. Declutter first. Don’t pay to store what you don’t need.

  3. Estimate size. Use online calculators, but lean slightly larger if unsure.

  4. Visit facilities. Seeing units in person helps.

  5. Talk to managers. Share your inventory; they can recommend the right fit.

FAQ: What if I Pick the Wrong Size?

If your unit is too small, you’ll have to upgrade (which can be inconvenient, but is possible). Too large, and you’ll overpay. When in doubt, opt for the slightly larger option for added flexibility.
