What Items Cannot Be Stored in a Storage Unit
Hazardous and flammable materials, perishable goods, living things, illegal items, and environmentally harmful substances are generally prohibited from storage units. These restrictions protect your belongings, the facility, other customers, and the local environment. Understanding what you cannot store helps you plan your move effectively and avoid costly rejections at the door.
Urban Self Storage in Bunbury and East Bunbury enforces these restrictions consistently across all secure storage facilities based on safety standards, insurance requirements, and legal obligations that apply to storage operators across Western Australia.
Why Storage Facilities Restrict Certain Items
Storage facilities restrict certain items for interconnected safety and legal reasons. Fire safety is the primary concern: flammable and combustible materials create genuine risk in enclosed environments where many people’s belongings are stored together.
Insurance liability is another major factor. Storage operators carry comprehensive insurance policies that explicitly exclude coverage for prohibited items. If a fire or chemical spill occurs involving restricted materials, the facility’s insurance won’t cover the damage.
Legal compliance also plays a critical role. Environmental protection laws, dangerous goods regulations, and fire safety standards all govern what storage facilities can legally accept. Storage operators who ignore these rules face significant penalties, licence suspension, or legal action. Urban Self Storage maintains compliance with all relevant Western Australian regulations.
Finally, storage unit rules protect the broader community. Hazardous materials stored improperly can leak, corrode, or combust. Perishable goods attract pests and create health hazards that spread throughout the facility and potentially into the surrounding area.
Hazardous and Flammable Materials You Cannot Store
Hazardous and flammable materials represent the largest category of prohibited items in storage units, posing immediate fire and explosion risks.
Fuels, gases and combustible liquids
Petrol, diesel, kerosene, and other fuel products are strictly prohibited. These ignite easily and burn intensely, presenting serious fire risk even in small quantities. Propane cylinders, butane canisters, and compressed gases are similarly banned because they can explode if damaged or exposed to heat.
Paint thinners, turpentine, and solvents are combustible and often prohibited. Water-based paints are sometimes allowed, check with Urban Self Storage before bringing any paint products. Fireworks and ammunition are combustible materials that storage facilities won’t accept.
Chemicals and corrosive substances
Cleaning chemicals, pesticides, herbicides, and fertilisers are generally prohibited due to corrosive or toxic compounds that can damage stored items and contaminate the facility. Drain cleaners, oven cleaners, and similar caustic products fall into this category.
Batteries, particularly car batteries and lithium types, are often restricted because they can leak corrosive acid or catch fire if damaged. Asbestos-containing materials are prohibited due to health risks and require specialist disposal through licensed facilities.
Perishable Goods and Living Things
Perishable items cannot be stored in self-storage units because they decompose, attract pests, and create health hazards. Food, whether fresh or packaged, will spoil and eventually leak, creating odours and attracting rodents and insects that spread throughout the facility.
Animal feed, hay, grain, and similar products also decompose and attract pests. Living creatures, pets, livestock, birds, fish, reptiles, and insects, cannot be stored. Storage units lack climate control, natural light, food, water, and proper ventilation for animals to survive. Plants require light, water, and specific temperature ranges to survive and will die and decompose without these conditions.
Illegal and Stolen Items
Storage units cannot be used for illegal drugs, illegally obtained weapons, counterfeit goods, or stolen merchandise. Facilities are required by law to refuse these items, and storing them puts you at legal risk.
Firearms and ammunition require special handling. Some facilities accept firearms under strict conditions, they must be unloaded, secured, and stored separately from ammunition. Many facilities prohibit firearms entirely. Urban Self Storage’s storage unit rules specify whether firearms are permitted, so contact the team before attempting to store any weapons.
Ensure you have proof of legitimate ownership or purchase before storing items acquired through house clearances or estate sales.

How to Prepare Items for Long Term Storage
Proper preparation prevents damage, pest attraction, and rule violations. Begin weeks before your move-in date.
Create a detailed inventory and compliance check
List every item you plan to store, organised by category: furniture, appliances, electronics, tools, and seasonal goods. For each item, verify it’s not on the prohibited list. Cross-reference your storage agreement from Urban Self Storage with each category. If you’re uncertain about any item, paint, batteries, garden chemicals, old electronics, contact the team before moving day.
Prepare items to prevent deterioration and pest attraction
Cleanliness is critical. Wipe down furniture, appliances, and goods to remove dirt and food residue that attract rodents and insects. Empty and defrost refrigerators completely, leaving ice or food inside creates mould, odours, and pest problems affecting neighbouring units. Run a rinse cycle with white vinegar through washing machines and dishwashers, then leave doors open for 24 hours before storage.
Drain fuel from lawn mowers, chainsaws, and petrol-powered equipment. Never store equipment with fuel in the tank; petrol evaporates in enclosed spaces and creates fire hazard. Remove batteries from cordless tools and electronics.
For moisture-prone items, electronics, documents, photographs, antique furniture, use silica gel packets or moisture-absorbing containers inside boxes. Refresh these packets every few months for long-term storage to prevent mould and corrosion.
Disassemble and pack strategically
Break down large furniture where practical. Beds, desks, dining tables, and shelving units take up significantly less space when disassembled. Keep all hardware in clearly labelled ziplock bags, then tape these to the corresponding furniture piece. Photograph the assembly process before disassembly for reassembly reference later.
Pack boxes securely with sturdy packing tape on bottom and top. Avoid overfilling boxes; heavy boxes are difficult to move and may collapse. Label each box on at least two sides with contents and room origin. Use permanent marker for durability. For long-term storage, consider colour-coded labels or a numbering system linked to a master inventory spreadsheet.
Wrap furniture in blankets, furniture pads, or moving blankets to prevent scratches. Use bubble wrap for smaller items and electronics. Avoid plastic sheeting directly against wood furniture; plastic traps moisture and causes mildew.
Organise your unit for access and safety
Place frequently accessed items, seasonal decorations, business inventory, toward the front. Store heavier items on lower shelves; lighter boxes go above. Never stack boxes higher than eye level; they become unstable and difficult to retrieve safely.
Leave a small aisle down the middle of the unit for safe movement and periodic inspections. Store valuable or fragile items in the middle of the unit, away from the door and exterior walls, to protect them from temperature fluctuations and frequent door openings.
Document and photograph valuable items
Photograph items before moving them into storage. Take clear photos of serial numbers on electronics, furniture condition, and any existing damage. Keep receipts, warranty documents, and proof of purchase for expensive items. Store digital copies in cloud storage for accessibility.
For business inventory or high-value goods, create a detailed spreadsheet listing each item, condition, approximate value, and unit location. Update this spreadsheet if you add or remove items.
Self Storage Insurance Requirements for Your Unit
Understanding self-storage insurance is crucial for protecting your belongings. Most storage facilities, including Urban Self Storage, do not carry insurance on customer items. Your belongings remain your responsibility, and you need appropriate coverage to protect against theft, damage, loss, or environmental harm.
Check your existing home and contents insurance
Review your current home or contents insurance policy. Many policies include some coverage for off-premises storage, but terms vary significantly. Some policies cover storage unit contents for limited periods (often 30 to 90 days), while others exclude storage units entirely.
Contact your insurer directly and ask:
- Are items stored in a self-storage unit covered under my current policy?
- If yes, what is the maximum coverage amount and duration?
- Are there exclusions for specific item types (electronics, jewellery, documents, business inventory)?
- What is the excess (deductible) if I make a claim?
- Do I need to notify the insurer before storing items?
- Are theft and vandalism covered, or only fire and weather damage?
Write down the answers and keep them with your storage agreement. If your existing policy doesn’t adequately cover storage units, you’ll need additional insurance.
Storage-specific insurance policies and what they cover
If your home insurance doesn’t adequately cover storage unit contents, you can purchase storage-specific insurance. This coverage typically protects against fire, theft, vandalism, water damage, and weather-related damage.

When you apply for storage insurance, you’ll need to provide:
- A detailed inventory of items being stored
- The approximate total value of all items
- The storage facility location and unit size
- The expected duration of storage
- Security features at the facility (CCTV, access control, on-site management)
Urban Self Storage’s 24/7 CCTV surveillance, access control systems, and secure perimeter fencing are security features that insurers consider when calculating premiums. Facilities with robust security typically qualify for lower insurance rates because theft risk is reduced.
What storage insurance typically excludes
Storage-specific policies have important exclusions. Most do not cover perishable goods, living creatures, illegal items, wear and tear, inadequate packing, lack of maintenance, or high-value items without documentation. Some policies exclude items stored for business purposes; commercial storage insurance may be required for stock, equipment, or inventory.
Read the policy document carefully before purchasing and ask the insurer to clarify any exclusions relevant to your items.
Documenting value and ownership for claims
If you need to make an insurance claim, you’ll need to prove ownership and value. Insurers typically require receipts or invoices, photographs, serial numbers, appraisals for high-value items, and bank or credit card statements.
Create a detailed inventory spreadsheet before moving items into storage. Include item description, approximate value, purchase date, and condition. Store digital copies in cloud storage for accessibility. Update the spreadsheet if you add or remove items.
How security features at Urban Self Storage reduce your insurance risk
Urban Self Storage’s security measures, 24/7 CCTV surveillance, electronic access control, secure perimeter fencing, and on-site management, reduce theft risk and may qualify you for reduced premiums on storage-specific policies. However, security measures do not eliminate the need for insurance. Insurance protects you against all types of loss, including damage from fire, water, weather, or pest infestation.
What to Do If You’re Unsure About Your Items
If you’re uncertain whether a particular item can be stored, contact Urban Self Storage directly before moving day. The team in Bunbury and East Bunbury can answer questions about specific items and explain what’s prohibited and why.
Many items fall into grey areas. Some storage facilities accept certain items others refuse. Rather than guessing, get clarification from your storage provider. Review your storage agreement carefully before signing and keep a copy for your records.
If you discover prohibited items after moving in, inform Urban Self Storage immediately. Don’t attempt to hide them. Facilities conduct regular inspections, and prohibited items will eventually be discovered.

Frequently Asked Questions
Why are flammable materials prohibited in storage units?
Flammable materials like petrol, diesel, paint thinners, and solvents pose serious fire and explosion risks in enclosed spaces. Storage facilities house many units in close proximity, so a fire in one unit could spread rapidly to others. Facilities restrict these items to protect all customers’ belongings and comply with fire safety regulations. Always check your storage agreement for the complete list of prohibited items.
Can I store food or perishable items in a storage unit?
No, perishable items including food, animal feed, and fresh plants cannot be stored in self-storage units. These items attract pests, decompose, and create odours that damage other customers’ belongings. Even sealed food packaging can break down over time. If you need to store non-perishable household goods during a move or renovation, ask the team about what’s permitted for your specific situation.
How do I check if my items are safe for storage?
Review your storage unit agreement carefully before moving items in. Most facilities provide a detailed list of prohibited items covering hazardous goods, perishables, illegal items, and living things. If you’re unsure about a specific item, contact the storage facility directly before bringing it to your unit. This prevents problems later and ensures you’re protected under your storage agreement and insurance.
What happens if I accidentally store a prohibited item?
If a prohibited item is discovered, the facility may require immediate removal at your expense. In serious cases involving hazardous materials, the facility could shut down your unit access, charge removal fees, or pursue legal action. Your storage insurance may not cover damage or loss caused by prohibited items. Always confirm what you can store before moving anything in, and contact the team if you have questions.
