Self Storage Insurance: Protection Plans vs Your Own Policy (2026)
Most storage agreements require your goods to be covered, but you may already have cover through your homeowners or renters policy, usually with a lower limit for storage. The cost question is really two questions: what your own policy pays for goods in storage, and whether the facility will accept it instead of selling you its plan. Plan prices are set by each operator, so this page sets out what to compare rather than printing a premium.

Do You Need Storage Insurance?
Short answer: you usually need proof of cover, but you may not need to buy a new policy. Check your renters or homeowners policy first. One homeowners form posted by the Maine Bureau of Insurance (form HO 3000 02 13, checked October 2026) covers personal property “anywhere in the world”, but caps property “located in a self-storage facility” at “10% of the limit of liability for Coverage C, or $1,000, whichever is greater.” If that limit covers what you are storing, ask the facility whether it will accept your policy instead of its plan.
Three Ways to Cover Stored Goods
Facility Protection Plan
Cost: Set by the operator, billed with rent
Coverage: Fixed limit tiers chosen at signing
Deductible: Per the plan terms
PROS
- +Bought at the counter, same day
- +No existing policy needed
- +Accepted by the facility by definition
CONS
- -Some are protection plans rather than insurance policies: read who pays claims
- -Limits and exclusions vary
- -May exclude business property
Homeowners or Renters Policy
Cost: Often nothing extra if you already have a policy
Coverage: Often a lower storage limit than at home
Deductible: Same as your policy
PROS
- +No extra premium if the limit is enough
- +Insurer regulated by your state
- +One policy for home and storage
CONS
- -Storage limit may be well below your contents limit
- -Claims go on your insurance history
- -Your deductible may be higher than the goods are worth
Separate Storage or Business Policy
Cost: Quoted by the insurer
Coverage: Chosen to match what you store
Deductible: Per the policy
PROS
- +Limit can match high-value contents
- +Independent of your home policy
- +The route for business inventory
CONS
- -Requires shopping around
- -Check the facility accepts it before you buy
- -Separate claims process
Limits Inside a Homeowners Policy That Catch People Out
The same filed form (HO 3000 02 13) shows the kind of sub-limits to look for in your own policy. Your insurer's wording may differ.

- ■Property away from the home used primarily for business: $1,000.
- ■Theft of firearms: $500. Theft of jewelry, watches and furs: $1,000.
- ■Flood, surface water and waves: excluded.

How Much Coverage Do You Need?
1. Value it
Estimate the replacement cost (not the original price) of everything going into the unit. Photograph it as you pack.
2. Find your storage limit
Read the storage or other-locations section of your policy, or ask your insurer to confirm the limit in writing.
3. Cover the gap
If the limit is below the value, ask your insurer about raising it, or compare the facility plan's tiers against a separate policy.
Questions for the facility: is cover compulsory, will you accept my own policy, what proof do you need, and if I buy your plan, who is the insurer or administrator, what is the limit, the deductible and the main exclusions?
