The single most common insurance misconception in the storage industry: tenants assume the facility's insurance protects their vehicle. It doesn't, in almost all cases.
Standard storage contracts explicitly transfer all of these risks to the tenant. The Self Storage Association publishes model contract language that every major facility uses some version of, and "tenant's property is stored at tenant's sole risk" appears in essentially every contract.
Translation: your comprehensive coverage — not theirs — is what pays when something happens. If you drop your coverage during storage, you have no protection for the most common failure modes.
Standard auto insurance has four main components. Only one is essential during storage.
Covers damage to your vehicle from non-collision causes: theft, vandalism, fire, flood, hail, falling objects, animal damage, glass breakage, weather events, riots. The Insurance Information Institute maintains a detailed breakdown of what comprehensive covers. Keep this coverage active at all times during storage. This is the single most important component — it covers ~95% of storage-facility incident types.
Covers damage from hitting another vehicle or object. You can't collide with anything if you're not driving, so collision is rarely useful during storage. Most insurers allow you to suspend collision during documented storage periods. Savings: typically 30-40% of the premium.
Covers damage you cause to others — their vehicle, their property, their injuries. Required by law in most states while driving. During storage, you're not driving, so liability is inactive. Most insurers allow full suspension of liability during stored periods (though some states require minimum liability even on stored vehicles — check with your carrier).
Covers damage caused to YOU by an uninsured or underinsured driver. Also irrelevant during storage. Usually suspended with liability.
Most major insurers offer a dedicated "stored" or "lay-up" mode for vehicles that aren't in use. The request process varies by carrier.
Online request through Progressive's app or website. Called "limited coverage" mode. Usually processed same-day. Requires confirmation that the vehicle is at a fixed storage address and non-operational.
Similar online process. Called "comprehensive only" mode in most GEICO products. Can be toggled on and off during your policy period.
Requires a call to your agent. Agent can reduce coverage to comprehensive-only; the change applies as of the date you request.
Similar to State Farm — agent-processed, usually same-day.
Has a formal "stored vehicle" endorsement available online. One of the easier carriers for active-duty military doing extended deployments.
Agent-processed. Has a specific "limited use" product for stored vehicles.
Agent-processed. Confirm minimum liability requirement in your state; Liberty Mutual historically requires a small amount of liability even in stored mode.
The day before you drive the vehicle again, toggle coverage back to full. Driving on a stored-mode policy is technically uninsured driving — you have no collision or liability coverage. Most carriers let you toggle back online or by phone in under 10 minutes, so there's no reason to delay.
For vehicles over about $25,000, specialty collector-car insurers often provide better coverage at lower cost than standard auto insurance. Their business model: assume limited annual mileage and priced storage, and pass the savings through.
The largest specialty insurer. Hagerty covers classic, exotic, modern collector, and increasingly some specialty daily-driver vehicles. Known for their valuation tools (the Hagerty Price Guide is an industry reference) and agreed-value policies. Typical premium: 25-50% less than equivalent standard auto coverage on the same vehicle.
Grundy specializes in antique and classic cars with unlimited mileage options (unusual among specialty insurers). Strong choice for collector-car owners who also drive their cars regularly to shows.
Founded in 1976, focuses on collectors with multi-vehicle collections. Agreed-value policies, spare-parts coverage, automobilia coverage (signage, memorabilia, etc.) that most standard auto policies don't offer.
Heacock is part of Hagerty now but maintains its own brand. Historically strong in the show-car and concours-level collector space.
Antique auto specialist, active since 1961. Particularly strong for pre-1970s vehicles where other insurers may not have comparable valuation data.
If you meet those conditions (most collector owners do), specialty insurance is almost always the better product.
Boat insurance policies often have built-in "lay-up" provisions that automatically suspend liability and collision during a stated off-season period. The National Marine Manufacturers Association and U.S. Coast Guard Office of Boating Safety both reference lay-up as a standard industry concept.
Typical lay-up periods:
Major boat insurers — Progressive Marine, BoatUS, Foremost, GEICO Marine, Allstate — all offer built-in lay-up discounts. Typical savings: 30-50% off the in-use premium during lay-up months.
Similar structure. "Lay-up" or "stored" mode suspends collision and liability while keeping comprehensive. Good Sam, Progressive, Farmers, Foremost all offer this. Some RV insurers have dedicated "full-timer" products for people who live in their RVs and rarely store them, and separate "recreational use" products that assume seasonal storage.
Typical RV insurance cost ranges:
What you'll actually pay for insurance during storage. All numbers assume the vehicle is in storage at a secure facility or a locked home garage.
| Vehicle type | Value | Standard auto in-use | Stored mode (comp only) | Collector policy (if applicable) |
|---|---|---|---|---|
| Commuter sedan | $18,000 | $90-$140/mo | $25-$40/mo | N/A |
| Pickup truck | $38,000 | $120-$180/mo | $35-$55/mo | N/A |
| Late-model SUV | $52,000 | $140-$220/mo | $45-$70/mo | N/A |
| Classic Mustang (1967-1970) | $75,000 | $180-$300/mo | $60-$100/mo | $30-$55/mo (agreed value) |
| Porsche 911 Turbo (modern) | $180,000 | $250-$450/mo | $90-$160/mo | $65-$120/mo |
| Ferrari collector | $400,000 | $450-$800/mo | $160-$280/mo | $140-$250/mo |
| Classic Harley-Davidson | $18,000 | $80-$140/mo | $20-$35/mo | $15-$30/mo (Hagerty) |
| Class A motorhome | $120,000 | $180-$300/mo | $60-$100/mo | N/A (use specialty RV) |
| 28-ft boat | $65,000 | $90-$160/mo | $35-$70/mo (lay-up) | N/A |
| Jet ski | $15,000 | $40-$80/mo | $15-$30/mo | N/A |
Your actual premium depends on driving record, credit score (most states), location, and coverage limits. The spreads above are typical mid-range quotes from comparison shopping across 5+ carriers.
This distinction is enormous for classic, collector, and specialty vehicles.
Pays the depreciated market value at the time of loss. Standard on most auto policies. How the carrier calculates market value: comparable sales data, condition adjustments, optional inspection.
The problem with ACV on appreciating vehicles: insurance carriers often apply depreciation even to vehicles that are actually appreciating. A 1970 Shelby Mustang might be worth $180,000 in the actual collector market but be valued at $60,000-$90,000 by a standard auto insurer's depreciation tables.
Pays a pre-negotiated insured amount regardless of market fluctuations. Standard on specialty collector-car policies. How it's established: professional appraisal, price-guide reference, or owner declaration with documentation.
The benefit: on total loss, you get exactly what the policy says. If you have a $180,000 agreed-value policy and the car is destroyed, you get $180,000 (less deductible). No arguing about market conditions or depreciation tables.
A collector has a 1967 Camaro SS valued at $120,000 in the current market. They have two policy options:
The agreed-value policy costs less AND pays more. This is why serious collectors almost always use specialty insurers.

Many storage facilities offer "tenant insurance" at checkout, typically $10-$40/month for $2,000-$10,000 of coverage on stored property. This is almost always overpriced compared to independent alternatives.
The facility has a captive-insurance arrangement with a third-party carrier. The facility collects the premium, remits to the carrier, and keeps a commission — often 40-60% of the premium. The actual underlying coverage could be bought directly from the same carrier for 40-60% less.
Before accepting facility insurance, ask your existing insurers whether your current policies extend to the storage facility. Usually yes — and if so, you're paying twice.
Comprehensive is essential — it protects against theft, fire, flood, vandalism, weather. Collision and liability can usually be suspended since you're not driving.
Typically 40-60% on the monthly premium. Specialty collector insurers can save another 20-40% on top.
No, in almost all cases. Facility insurance covers their property and operational liability. Your vehicle is protected by your comprehensive coverage, not theirs.
Comprehensive auto insurance covers flood damage to vehicles. You may want separate coverage for contents inside the vehicle (RV appliances, personal items).
ACV pays depreciated market value; agreed value pays a pre-negotiated amount. Agreed value is dramatically better for appreciating classic cars.
Legally sometimes, practically never a good idea. Storage is peak-risk for theft and weather, and those are exactly what comprehensive covers.
Contact Hagerty, Grundy, American Collectors, or J.C. Taylor directly. They'll require vehicle details and an appraisal or price-guide valuation. Switching usually takes 1-2 weeks.
Sometimes. Some insurers charge a small premium for outdoor storage in high-theft or high-weather regions. Indoor facilities with documented security often qualify for discounts.
Update your coverage. Classic-car policies let you increase agreed value annually. Standard auto policies don't adjust for appreciation — another reason specialty insurers are better for collectors.
Usually yes, either through a separate contents rider or via your homeowners / renters policy which often extends to off-site storage. Confirm with your agent.
