Self Storage Insurance: What You Need and What It Costs (2026)
Most facilities require insurance, but you might already be covered. Here is how to avoid paying twice and how to choose the right coverage level.
Do You Need Storage Insurance?
Short answer: You need proof of coverage, but you may not need to buy a new policy. Check your renters or homeowners insurance first. Many policies include off-premises coverage that extends to storage units at no additional cost. If you are already covered, decline the facility's plan and save $120 to $240 per year.

How Much Coverage Do You Need?
$2,000 - $5,000
$10 - $12/mo estimated
Storing low-value items: holiday decorations, old furniture, boxes of household goods. Facility insurance is sufficient.
$5,000 - $15,000
$8 - $15/mo estimated
Storing furniture, electronics, or a mix of household items worth moderate amounts. Third-party insurance gives better value.
$15,000 - $25,000+
$15 - $30/mo estimated
Storing high-value items: antiques, art, expensive furniture, business inventory. Need a dedicated policy with adequate limits.
Rule of thumb: estimate the replacement cost (not original price) of everything you are storing. Most people overinsure for low-value items and underinsure for high-value collections.
