Storage units can provide temporary space for furniture, packed household belongings, seasonal equipment and other possessions during a move. However, not everything can be stored safely or legally.
Perishable food, hazardous chemicals, fuel, living things, wet belongings and irreplaceable documents should generally remain outside a storage unit. Temperature-sensitive possessions may also require climate-controlled conditions rather than ordinary storage.
Understanding what should and should not go into a storage unit can protect your belongings, prevent pest and mold problems and help you avoid violating the storage agreement.

Read the Storage Agreement First
Review the written agreement before placing any belongings inside the unit.
Look for information about:
- Prohibited items
- Access hours
- Payment deadlines
- Late fees
- Security
- Insurance requirements
- Climate control
- Vehicle storage
- Locks
- Emergency access
- Abandonment procedures
- Property liens
- Notice requirements
- Unit inspections
Ask for clarification when the rules are unclear. Do not assume an item is permitted simply because it fits inside the unit.
Create photographs and a written inventory before storage begins.
Furniture
Furniture is commonly stored during a move, but improper preparation can lead to scratches, warping, odors or mold.
Clean Furniture First
Food crumbs, body oils, dirt and moisture can attract pests or damage surfaces over time.
Vacuum upholstered furniture and allow it to dry completely. Clean wood, metal, leather and other materials according to manufacturer instructions.
Disassemble When Appropriate
Taking apart tables, bed frames and shelving can reduce the required space.
Before disassembly:
- Photograph the assembled furniture.
- Label each section.
- Place hardware in a resealable bag.
- Attach the hardware securely or store it in a designated parts box.
- Keep assembly instructions.
Do not disassemble furniture beyond your ability to reassemble it safely.
Use Breathable Protection
Protect furniture from dust without trapping moisture. Plastic wrapped tightly around certain materials for an extended period can hold condensation against the surface.
Use appropriate furniture covers, blankets or breathable materials based on the item and storage environment.
Avoid placing furniture directly against exterior walls when doing so could expose it to condensation.
Clothing and Fabrics
Clothing, bedding, curtains and other fabrics can be stored when they are clean and completely dry.
Before packing:
- Wash or clean the fabric.
- Dry it thoroughly.
- Remove stains.
- Fold it carefully.
- Use suitable containers.
- Label the contents.
- Avoid overpacking.
Moisture trapped inside a container can lead to mold and odor.
Avoid storing clothing inside thin plastic bags for extended periods. Strong containers that protect against dust and pests are generally more suitable.
Delicate, antique or valuable textiles may require specialized preservation conditions.
Books
Books can be stored, but they are vulnerable to moisture, high temperatures, pests and excessive weight.
The Library of Congress recommends a cool, relatively dry environment for book storage and advises against placing valuable collections in locations with uncontrolled temperature, humidity or flood risk.
When packing books:
- Use small, strong boxes.
- Place heavy books at the bottom.
- Pack books flat or vertically with the spine down.
- Fill empty spaces.
- Keep boxes off the floor.
- Avoid overloading.
- Keep books away from liquids.
Read the Library of Congress guidance on storing books when preparing valuable or long-term collections.
Photographs and Family Records
Photographs can deteriorate when exposed to heat, humidity, light and poor-quality packing materials.
The Library of Congress notes that high humidity can damage photographic materials. Its guidance on the care and storage of photographs explains appropriate enclosures and environmental conditions.
For important photographs:
- Create digital backups.
- Use suitable protective sleeves.
- Place them in rigid archival-quality containers.
- Avoid damp or hot spaces.
- Keep boxes away from the floor.
- Consider climate-controlled storage.
- Transport irreplaceable photographs personally when possible.
Original birth certificates, passports and critical financial or legal records should not be placed somewhere you cannot access immediately.
Electronics
Televisions, computers, audio equipment and gaming systems may be sensitive to heat, cold, humidity and condensation.
Before storing electronics:
- Back up important data.
- Remove batteries when appropriate.
- Photograph cable connections.
- Label cords.
- Clean and dry the equipment.
- Use original packaging when suitable.
- Protect screens.
- Keep equipment off the floor.
Climate control may be appropriate when temperature or humidity fluctuations could damage the equipment.
Do not store electronics with leaking batteries, liquids or cleaning chemicals.
Allow cold equipment to return gradually to room temperature before use when condensation may be a concern.
Household Appliances
Refrigerators, freezers, washing machines, dryers and small appliances must be clean and dry before storage.
Refrigerators and Freezers
Empty, defrost, clean and dry them completely. Keep doors slightly open when safe and permitted to prevent trapped odors and moisture.
Do not store food inside.
Washing Machines
Drain the machine and hoses according to manufacturer instructions. Residual water may leak or contribute to mold.
Small Appliances
Remove food, grease, water and detachable components. Pack fragile parts separately.
Follow manufacturer instructions for transportation and storage.
Kitchenware
Dishes, cookware and small kitchen items are generally suitable for storage when clean and dry.
Pack fragile items individually and label the boxes. Do not place heavy cookware above glassware or ceramics.
Our guide on how to pack fragile items for moving explains how to protect dishes, glasses and other breakable belongings.
Avoid storing food residue, dirty dishes or damp kitchen towels.
Tools and Equipment
Hand tools and power tools can usually be stored when permitted.
Before storage:
- Remove dirt.
- Clean oil or residue.
- Protect sharp edges.
- Secure loose parts.
- Remove or protect batteries.
- Take steps to prevent rust.
- Label heavy boxes.
- Drain prohibited fuel.
Do not store gasoline, propane or other flammable fuels with equipment.
Follow the manufacturer’s instructions when preparing lawn equipment, generators or power tools.
Seasonal Decorations
Holiday decorations and seasonal household items are generally suitable for storage.
Use rigid, labeled containers and protect fragile ornaments individually.
Group decorations by season rather than placing unrelated items together. This makes it easier to retrieve what you need without opening every box.
Avoid storing wax candles, delicate decorations or temperature-sensitive items in extreme heat.
Sports and Outdoor Equipment
Clean and dry bicycles, camping equipment, sports gear and outdoor furniture before storage.
Remove:
- Soil
- Grass
- Food
- Moisture
- Fuel
- Prohibited pressurized containers
Tent fabric, sleeping bags and other textiles should be completely dry to prevent mildew.
Inflatable equipment should be cleaned and stored according to manufacturer instructions.
Items That Should Not Go Into a Storage Unit
Some belongings create serious safety, legal or preservation concerns.
Perishable Food
Meat, dairy products, produce, frozen food and prepared meals require controlled temperatures.
The Food and Drug Administration explains that refrigerated foods generally need to remain at 40°F or below, while freezers should remain at 0°F. An ordinary storage unit is not designed to provide food-safe refrigeration.
Perishable food can spoil, create odors and attract pests.
Open or Improperly Packaged Food
Even shelf-stable food can attract pests when packaging is open, damaged or poorly sealed.
Many storage agreements prohibit food entirely. Review the applicable rules before storing unopened canned or dry goods.
Do not store food in cardboard boxes when insects or rodents may reach it.
Fuel and Flammable Materials
Gasoline, propane, fireworks and similar materials create fire and explosion risks and are generally prohibited.
Do not store:
- Gasoline
- Diesel fuel
- Propane cylinders
- Lighter fluid
- Fireworks
- Kerosene
- Flammable solvents
- Fuel-filled equipment
Emptying a container does not automatically make it safe. Follow applicable disposal and equipment-preparation guidance.
Paints, Chemicals and Hazardous Waste
Some paints, cleaners, oils, batteries and pesticides contain ingredients that require special care.
The Environmental Protection Agency explains how to identify and manage household hazardous waste.
Contact your city or county waste authority for local disposal instructions. Do not pour chemicals into drains, combine products or transfer them into unmarked containers.
Wet or Damp Belongings
Never place wet furniture, clothing, boxes or equipment into storage.
Moisture can cause:
- Mold
- Mildew
- Odor
- Rust
- Staining
- Box failure
- Damage to nearby belongings
Allow every item to dry completely before storage. Replace damp cardboard rather than hoping it will dry inside the unit.
Plants
Plants require light, water, air circulation and suitable temperatures. A storage unit is not an appropriate environment for living plants.
Soil and plant material may also attract insects or create moisture problems.
When moving across state lines, agricultural rules may affect which plants can travel to the destination.
Animals
Animals should never be left inside a storage unit. Units do not provide appropriate ventilation, temperature control, sanitation, water or supervision.
Leaving an animal in a storage unit may also violate animal-welfare laws.
Cash and Jewelry
Cash, jewelry, precious metals and highly valuable collectibles should be kept in a more appropriate secure location.
Review insurance limitations before storing anything valuable. Storage security features do not guarantee protection against theft, fire, water or other damage.
Irreplaceable Documents
Avoid storing original:
- Passports
- Birth certificates
- Social Security records
- Immigration documents
- Property documents
- Essential medical records
- Financial documents
- Family records
- Current moving paperwork
You may need these documents without notice. Keep them secure and accessible, with protected digital copies when appropriate.
Medication and Medical Equipment
Essential medication should remain available and within appropriate temperature conditions.
Many medications and medical supplies can be damaged by heat, freezing or moisture. Follow instructions from the healthcare provider, pharmacist or manufacturer.
Do not place equipment required for daily health needs somewhere that may be inaccessible outside business or access hours.
Items You Do Not Own
Do not store borrowed, rented or leased property without permission.
Review the relevant agreement before placing rented furniture, equipment or vehicles into long-term storage.
Illegal or Stolen Property
Illegal substances, stolen goods and items that cannot lawfully be possessed should never be placed in storage.
A private storage unit does not provide immunity from criminal or civil laws.
Firearms and Ammunition
Firearm and ammunition rules vary significantly according to jurisdiction and storage policy.
Before storing anything in this category, verify:
- Federal requirements
- State and local laws
- Facility policy
- Access-control requirements
- Insurance terms
- Fire-safety rules
- Storage and transportation requirements
Do not assume firearms and ammunition can be stored together or that the facility permits either.
Is Climate-Controlled Storage Necessary?
Climate-controlled storage may be appropriate for items sensitive to temperature and humidity.
| Item | Climate Control May Be Helpful Because |
|---|---|
| Electronics | Condensation, heat and humidity can affect components |
| Wooden furniture | Temperature and moisture changes may contribute to warping |
| Leather | Heat and humidity may cause drying, staining or mold |
| Photographs | Humidity and heat can accelerate deterioration |
| Books and documents | Moisture can cause mold, distortion and staining |
| Artwork | Materials may react to environmental changes |
| Musical instruments | Wood, adhesives and finishes may be sensitive |
| Antiques | Older materials may require stable conditions |
| Collectibles | Heat and moisture may reduce condition and value |
| Delicate textiles | Humidity can contribute to mold and deterioration |
Climate control reduces certain environmental risks but does not eliminate them. Verify the temperature and humidity conditions described in the agreement.
How to Prepare a Storage Unit
Inspect the unit before bringing in belongings.
Check for:
- Water stains
- Active leaks
- Unusual odors
- Pest evidence
- Damaged walls or ceiling
- Door and lock problems
- Standing water
- Excessive humidity
- Obstructed access
Photograph the empty unit and report concerns before moving anything inside.
How to Pack a Storage Unit
Plan the layout before loading.
Keep Belongings Off the Floor
Use appropriate shelving or raised supports when permitted. This can reduce exposure if minor water enters the unit.
Leave an Access Path
Create a clear path from the entrance to the back. Do not pack belongings so tightly that nothing can be reached.
Place Heavy Boxes at the Bottom
Stack only strong, similarly sized boxes. Do not place heavy containers over fragile belongings.
Keep Frequently Needed Items Near the Front
These might include:
- Seasonal clothing
- Important household supplies
- Children’s equipment
- Work materials
- Tools
- Holiday decorations
Avoid Exterior Walls When Appropriate
Temperature and condensation may be greater near some walls. Leave air space when possible.
Create a Storage Inventory
Record everything placed inside.
| Inventory Detail | Example |
|---|---|
| Box number | Storage 14 |
| Contents | Winter clothing |
| Location | Front-right shelf |
| Condition | Clean and dry |
| Photograph | Yes |
| Date stored | September 10 |
| Approximate value | $300 |
| Retrieval priority | Seasonal |
Take photographs of valuable belongings and the completed unit. Keep the inventory outside the unit so it remains accessible.
Review Insurance and Risk
Do not assume that the facility is financially responsible for every type of loss.
Review:
- Existing homeowners or renters coverage
- Separate storage coverage
- Deductibles
- Coverage limits
- Excluded events
- High-value-item limits
- Documentation requirements
- Security requirements
Keep receipts, photographs, serial numbers and inventory records.
Insurance terms are separate from the storage unit’s physical security features.
Inspect Stored Belongings Periodically
Long-term storage should not be treated as completely maintenance-free.
When access is permitted, check for:
- Water
- Mold
- Pests
- Odors
- Collapsed boxes
- Rust
- Temperature-related damage
- Unauthorized access
- Lock problems
Update your inventory when items are added or removed.
Common Storage Mistakes
Avoid:
- Storing damp belongings
- Placing boxes directly on the floor
