Storage units work well for most household items, furniture, seasonal goods, and business inventory. Facilities restrict flammable materials (gasoline, propane, paint thinner, chemicals), perishable food, plants, animals, and illegal items. Firearms, ammunition, and valuable items like jewelry vary. Some facilities prohibit them entirely, while others allow them with restrictions. Storing prohibited items can violate your lease agreement and result in access restrictions. Review your lease's prohibited items section to avoid issues.
