What Not To Put
In Storage
The Basics
Three Categories,
Not One
There are three different lists and people tend to blur them. There is what a facility prohibits in its contract, which is mostly about fire, flooding and pests. There is what a moving company cannot legally transport, which is a shorter and stricter list governed by hazardous materials rules. Then there is the largest category, things that are perfectly legal to store and a bad idea anyway, because they will be ruined by the time you come back. Most of what goes wrong falls into that third group.
Nothing flammable or combustible, anywhere
Gasoline, propane, paint thinner, lighter fluid, fireworks, ammunition primers. Facilities prohibit them and movers cannot carry them. Empty and drain fuel from mowers and generators before either.
Nothing alive and nothing that was recently food
Plants, pets and perishables. Also the half used bag of rice you did not think about, which is how a unit becomes a pest problem for the whole row.
Anything damp will ruin everything near it
A washing machine that was not drained, a fridge stored sealed, a mattress that went in slightly wet. Mold does not stay in one place.
Documents, photographs and electronics need climate control
Or they need to be somewhere else entirely. Inland San Diego heat in a metal unit is genuinely destructive to adhesives, tapes, vinyl and battery cells.
Do not store anything you would panic about losing
Passports, deeds, jewelry, irreplaceable photographs. Not because facilities are unsafe, but because access takes time you may not have in an emergency.
The Lists
What Is Actually
Prohibited
Flammables and fuels
Gasoline, diesel, propane, kerosene, lighter fluid, paint thinner, acetone. Prohibited by facilities and not transportable by a household goods carrier.
Explosives and ammunition
Fireworks, flares, ammunition and primers. Firearms themselves vary by facility and by law, so ask rather than assume.
Corrosives and pool chemicals
Acids, chlorine, muriatic acid and pool shock. These damage other property even when sealed, and chlorine in a hot unit is a genuine hazard.
Perishables and open food
Anything that can rot, and anything sealed that a rodent can smell. Pet food is the most commonly forgotten item on this list.
Living things
Plants and animals, without exception. Plants also carry pests into a facility where they will spread.
Wet or damp items
Not prohibited so much as guaranteed to cause damage. Drain appliances, dry everything, and leave fridges and washers propped open.
Allowed But Unwise
Legal To Store,
Bad Idea Anyway
Candles and anything wax based
An inland unit in August will reduce them to a puddle that spreads into whatever is beneath.
Vinyl records, tapes and film
Heat warps vinyl and degrades magnetic tape. If it matters, it wants climate control or a cupboard at home.
Batteries and battery powered devices
Lithium cells do not like heat, and a leaking alkaline battery ruins the device it is in. Remove batteries from anything going into storage.
Important documents
Legal papers, deeds, passports and tax records. Not because they will be damaged, but because retrieval takes a trip, and you will want them on a day when you cannot make one.
Upholstered furniture without a cover
Fabric absorbs whatever is in the air over months. Cover it, do not just push it against a wall.
Local Notes
San Diego Heat
And Humidity
The two local conditions worth planning around pull in opposite directions. Inland, through El Cajon, Santee, Lakeside, Escondido and the East County valleys, summer heat inside a metal unit is significantly higher than the outside temperature, and it degrades adhesives, warps vinyl and shortens battery life. On the coast, through Pacific Beach, Ocean Beach, Imperial Beach and up the coastal strip, heat is less of an issue and humidity is more, which matters for timber furniture, leather, artwork and paper. If your belongings include any of those categories, climate control is a real decision rather than an upsell. Our storage page covers what we hold directly, and our page on what movers can and cannot move covers the transport side of the same question.
