Most storage facilities require some form of insurance as a condition of renting. And even when they don't require it, anything you've stored is at risk from theft, fire, flooding, and pests. Here's what you need to know before you sign a rental agreement.
Does Your Existing Insurance Cover Storage Units?
Homeowner's Insurance
Most standard homeowner's policies extend off-premises coverage to belongings stored in a storage unit — typically at 10% of your personal property coverage limit. So if your home is insured for $200,000 in personal property, you'd have about $20,000 in coverage for stored items.
Caveats:
- Your deductible applies.
- Coverage is usually ACV (actual cash value), not replacement cost — meaning you get what a used item is worth, not what it costs to replace it.
- Flooding and vermin damage are commonly excluded.
Renter's Insurance
Same structure as homeowner's — off-premises coverage typically at 10% of your policy limit. A $30,000 renter's policy gives you $3,000 in storage coverage, which is fine for clothes and furniture but inadequate for electronics, musical instruments, or jewelry.
Action: Call your insurer before signing a storage lease. Ask specifically: what is my off-premises storage coverage limit, and what perils are excluded?
Facility-Offered Insurance
Almost every storage facility sells insurance at the point of signup — usually $8–$25/month for $2,000–$10,000 in coverage. It's convenient, but there are limitations:
- Coverage limits are often low relative to cost.
- Many policies exclude flooding, mold, and "mysterious disappearance" (theft with no signs of forced entry).
- You're buying from the facility, who benefits from low payouts.
That said, facility insurance fills the gap when your homeowner's/renter's policy doesn't extend off-premises, or when you need higher limits than your existing policy provides.
What Storage Insurance Typically Covers
| Peril | Typically Covered | Often Excluded |
|---|---|---|
| Fire and smoke | ✓ | |
| Theft (forced entry) | ✓ | |
| Vandalism | ✓ | |
| Water damage (burst pipe) | ✓ | |
| Flooding (rising water) | ✗ | |
| Mold and mildew | ✗ | |
| Vermin / pest damage | ✗ | |
| Theft (no forced entry) | ✗ | |
| Vehicle / boat damage inside unit | ✗ |
What Is Never Covered
Regardless of the policy source, these items are nearly universally excluded from storage insurance:
- Cash, coins, and precious metals
- Jewelry above a low sub-limit ($500–$1,000 typically)
- Fine art without a separate rider
- Firearms
- Business inventory and commercial merchandise
- Vehicles (need a separate auto or marine policy)
How Much Coverage Do You Actually Need?
Take 10 minutes to do a rough inventory of what you're storing. Estimate the replacement value — not what you paid years ago, but what it would cost to buy the equivalent today.
- Furniture set: $800–$3,000
- Electronics (TV, laptop, monitor): $500–$2,000
- Clothing: $500–$2,000
- Bikes or sports equipment: $300–$1,500
- Musical instruments: $200–$5,000+
Add it up. If your total exceeds your existing coverage limit by more than a few hundred dollars, supplemental insurance is worth it.
Frequently Asked Questions
Does renter's insurance cover a storage unit?
Usually yes, at 10% of your personal property limit. A $25,000 renter's policy gives you $2,500 in off-premises storage coverage. Check your policy declarations page for your specific limit and call your insurer to confirm storage units are included.
What happens if someone breaks into my storage unit?
File a police report immediately — most insurance claims require it. Document the loss with photos and a list of missing items with estimated values. Contact your insurer within 24–48 hours. If you have facility insurance and home/renter's insurance, you can only claim from one — you can't double-collect.
Is facility insurance worth it?
It depends. If your renter's or homeowner's policy already provides adequate off-premises coverage, facility insurance is often redundant. But if you're renting without those policies, or if you're storing high-value items that exceed your existing limits, facility insurance is a reasonable stopgap.
