Before moving your items into self storage, be sure to double-check that everything you have is safe to store. Here’s a quick rundown of the items that we allow to be stored:

Medical & Pharmaceutical Supplies

If you’re a sales representative for a medical or pharmaceutical supply company, self storage can be a convenient solution for keeping your products organized and easily accessible without cluttering up your office or filling your car trunk. Most medical supplies are allowed (as long as they aren’t radioactive), but check with your Extra Space Storage facility manager just in case.

Construction, Landscaping, & Other Service Tools

Do you operate a construction, landscaping, or other home service business? You can store your tools and equipment at Extra Space Storage. Trailers, mowers, plumbing supplies, building materials, and more are acceptable to store at our facilities. If there’s something you’re not sure is on the “safe list,” ask a manager!


Vehicles of all sizes can be stored with Extra Space Storage! We offer indoor, covered, and outdoor vehicle storage options throughout the country for motorcycles, cars, business vans, small trucks, boats, jet skis, snowmobiles, trailers, campers, and RVs. The only stipulations are that your vehicle must be registered, insured, and in operational condition.

Some items may seem as though they’re safe to store at home or at your business, but we don’t allow them at Extra Space Storage. Here’s a quick rundown of the items that we do NOT allow to be stored:

Combustible, Flammable, Hazardous, or Toxic Materials

If you’re wondering what liquids or materials you shouldn’t keep in your storage unit, it’s anything that is considered inherently dangerous. That includes, but is not limited to:

  • gasoline

  • compressed gas

  • propane tanks

  • kerosene

  • lamp & motor oil

  • acid

  • grease

  • corrosives

  • fertilizers

  • paint

  • cleaners

  • narcotics

  • fireworks

  • products containing asbestos

  • radioactive equipment or supplies

  • hazardous, toxic, or biological waste

Perishable Food

Perishable food and even pet food is not allowed to be kept at Extra Space Storage. The storage of produce, meat, and any item that may spoil can attract unwanted pests and will result in the termination of your lease agreement.


When it comes to plants, you cannot store any (living or dead) inside an Extra Space Storage unit. Plants can attract pests and cause an infestation that does irreparable damage to both your unit and the stored belongings of other customers at our facility.


In the event that you have extra tires—meaning more than the four attached to your vehicle—you may not use a storage unit to keep these items. The cost to dispose of tires puts a strain on facility owners, and the difficulty in putting out a tire fire (should they catch fire) can create a larger problem.

Yourself or Your Animals

No matter what, you or any animal you own is prohibited from living in your storage unit at Extra Space Storage. It’s illegal, and it puts you and other storage customers at risk. So don’t do it!
