General Self Storage Information


  • Do not store hazardous or toxic materials OR flammable liquids or gases OR foods. If you are not sure you should store something, ask the staff!
  • Do not store any combustibles! Do not store items such as propane tanks, old paint, cleaning fluids, gasoline or other things that might create or intensify a fire. Why risk your possessions just to keep a few cents worth of leftovers?
  • Remember, you alone are responsible for providing insurance on your property. You must buy insurance coverage yourself and you must pay the premium yourself; we do not insure your goods.  Use the best lock possible to protect your valuables.
  • Remember that only the tenant is legally entitled to enter the storage space unless other arrangements have been made with the self storage facility; for example, if you want friends and members of your family to use your storage space, you must list them under access rights on the rental agreement.
  • Visit your self storage space on occasion to check the condition of your possessions; occasionally move or shift your goods so that you see all sides of them. Report any problems immediately.
  • When moving out of storage, give at least 10 days written notice on the Great Spaces Move Out form. Take everything and don’t leave any trash. Leave the unit in broom-clean condition. Remove your lock.  Check out with the office when you have completely moved out.
  • If storing bedding, clothing or furniture covered in fabric or property that may be affected by changes in temperature, it may be wiser to rent climate-controlled space to provide a better storage environment for your personal possessions. Be certain that everything stored is dry, as any moisture may cause mildew. If you move during rain, dry off your goods before placing them into storage. Do not store anything that is wet; moisture is bad for virtually all property or goods.
Packing Tips


  • Fill boxes to capacity. Partially full or bulging boxes may collapse or tip over while stored.
  • Label your cartons and goods. This will make accessing items much easier.
  • Books and documents: Pack books flat to protect spines; use small boxes to avoid cartons that are too heavy to move easily. Put heavy items on bottom.
  • Dishes and glassware: Glass items should be individually wrapped; use blank wrapping paper for best results; “nest” cups and bowls, stand plates and platters; fill air pockets with wrapping paper or foam peanuts; don’t put breakables under other boxes.
  • Mirrors, windows, screens: Wrap all glass well; store on edge, not flat.
  • Lamps: Pack lamp shades separately; use blank paper to wrap lamp shades and other property that may be damaged by ink stains from regular newsprint.
  • Furniture: Stand sofas and mattresses on end; disassemble beds and tables; wrap legs in wrapping paper; keep upholstery off floor; place loose, light plastic dust covers or sheets over furniture.
  • Appliances and electronics: Clean appliances thoroughly. Refrigerators and freezers must be defrosted and dry and washing machines completely drained. Remove doors of appliances and store separately; desiccants (drying agents) should be used and containers checked and emptied regularly. Gasoline must be completely drained from items stored in climate controlled units.
  • Bicycles:  Wipe a few drops of oil on bicycles and tools to prevent rusting, then store these items away from furniture to avoid oil staining.
  • Clothes:  Wardrobe boxes allow you to store your clothing on hangers.  Shoes can be stored in the bottom of wardrobe boxes, while folded clothing can be stored in boxes or dresser drawers.
  • Leave enough room for a walkway or aisle to the rear of the unit.  Don't over pack the unit!
  • Keep items that you will need to get access to more frequently at the front of your unit.
  • Great Spaces caries a complete selection of moving and packing supplies.  We carry a complete line of the boxes, tape, mattress covers, paper, peanuts, locks, etc.
