  • Introduction

    Storage units are secure, enclosed spaces that people rent to store possessions they aren't using or they don't have space for in their homes. Some of the most popular items to put in a storage unit are old furniture, vehicles, seasonal clothing, mattresses, toys, art, and other collectibles.

    Storage units are leased from the owner of a storage facility, which usually has many of such units on a single lot. Units are typically rented per month, with a rental agreement that details activities and items that are prohibited in the unit.

    At some facilities, there are indoor and outdoor units. The indoor units are sometimes climate-controlled. Units usually come in a range of sizes for different amounts of storage, with the price fluctuating based on the size and other amenities like climate control and electricity.
  • How much do storage units cost on average?

    The average cost of renting a storage unit can fall in a range between $20 and $450 per month. The variance in price depends on a variety of factors, such as size, the value of the items being stored, and whether it is temperature controlled.

  • Can you live in a storage unit?

    No. Living in a storage unit violates the rules of most storage unit rental companies, and most local and federal housing laws require that the owners of a storage facility evict anyone found living in one of the units.

  • How can you figure out what size storage unit you need?

    To select a storage unit big enough to fit your belongings but not so large that you'll be paying for unfilled space, put the possessions you intend to store in one place, calculate the approximate volume by measuring the height, length, and width of the load and multiplying them together.

  • How do you know if you need a storage unit?

    If you have more possessions than you have space to store them in your home, you may need a storage unit. It's a practical, cost-effective option to put things that you don't use often or are not appropriate for the current season in another location.

  • Does homeowners insurance cover a storage unit?

    Most homeowners insurance policies don't cover storage units automatically. If your homeowners policy has coverage for "off-premises personal property," items in a storage unit are usually included.

  • How do you store clothing in a storage unit?

    An important consideration when storing clothing in a storage unit is making sure it stays dry. When storage facilities are not climate-controlled, you'll want to use a vacuum-sealed bag or a wardrobe box to protect your clothes against moisture and insects.
