Bring it with you: this guide is also available as a printable one-page checklist you can carry on the tour.
A supercar storage facility will always look impressive on Instagram. Polished floors, dramatic lighting, a row of GT3s under covers — none of it tells you whether your car will come out in twelve months better than it went in. The difference between a professional facility and an expensive parking garage lives in details you can only confirm in person: setpoints on a wall panel, a fire suppression head, a clause in the contract.
This checklist is built for a walkthrough. Every point below is something you can physically see, ask about, or request in writing during a single tour. Work through it in order — a well-run facility expects these questions and answers them without hesitation. It's the same territory we cover when we vet operators for this directory; see how we verify facilities for the full standard.
Environment: The Room Itself
1. Stated temperature and humidity setpoints — and visible equipment
Ask for numbers, not adjectives. "Climate controlled" means nothing without setpoints. You want to hear a specific target — commonly somewhere in the 60–75°F range for temperature and roughly 40–55% relative humidity — and then you want to see the hardware that delivers it: dedicated dehumidifiers or a desiccant system, thermostats or a monitoring panel, and ideally a data logger showing history rather than a single moment in time. Humidity is the one that kills cars. Sustained humidity above about 60% invites corrosion on brake rotors, fasteners, and unprotected aluminum, and encourages mold in leather and Alcantara interiors. This matters everywhere, but it's non-negotiable in humid markets — if you're comparing exotic car storage in Tampa, dehumidification capacity should be your first question, not your tenth.
2. Fire suppression type
Look up. A modern facility should have an actual suppression system, not just extinguishers on the wall. Ask what type: wet-pipe sprinklers are common and effective, but pre-action systems are preferable in vehicle storage because they won't dump water from an accidentally damaged head — water only enters the pipes after a separate fire-detection event. (Dry-pipe systems, despite the name, do discharge from a damaged head; they exist for freeze protection.) Some high-end facilities also use clean-agent systems in enclosed private bays. Whatever the answer, ask when it was last inspected; suppression systems carry inspection tags with dates on them, and you can read the tag yourself.
3. Floor condition and vapor barriers
Concrete transmits ground moisture upward, straight at your undercarriage. Look for sealed or epoxy-coated floors in good repair — no cracking, no dusting, no efflorescence (the white powdery mineral bloom that signals moisture migrating through the slab). Ask whether the slab was poured over a vapor barrier; older buildings often weren't, in which case the coating and the dehumidification system have to work harder. Sealed floors also make fluid leaks obvious, so problems get spotted early.
4. Spacing between vehicles and dedicated bays
Door dings don't care what the neighboring car cost. Vehicles should be spaced so that a door can open fully without contact — roughly three feet of clearance between cars is a reasonable benchmark — and there should be clear lanes for moving cars in and out without shuffling five others first. If the facility offers dedicated bays or private enclosed units, ask whether your car keeps the same spot or gets repositioned as inventory changes. Repositioning means more cold starts and more low-speed maneuvering around other people's cars.
Security: Who Gets In, and What Gets Recorded
5. Camera coverage and access logs
Walk the floor and count blind spots. Coverage should include every entrance, every vehicle area, and the exterior approaches — and footage should be recorded and retained, not just displayed live on a monitor. Then ask the more revealing question: how is access logged? Every entry into the storage area should generate a record — key fob, PIN, or biometric — tied to a specific person. If the answer is a shared door code, everyone with the code is anonymous, and the cameras are your only record of who stood next to your car.
6. Alarm system and monitoring
An alarm that rings locally is a noise; an alarm that's centrally monitored is a response. Ask whether intrusion and fire alarms are monitored 24/7 by a third-party service that dispatches police or fire, and whether anyone is on site overnight. Also ask what happens on a signal after hours — who gets called, and how fast someone with keys can be at the building.
7. Insurance: garagekeepers coverage, certificate on request
This is the point most owners skip and most regret. Ask specifically whether the facility carries garagekeepers legal liability coverage — the policy type that covers customer vehicles in the facility's care, custody, and control — and whether that coverage is "direct primary" (pays first, regardless of the facility's fault), "direct excess" (pays regardless of fault, but only above what your own policy covers), or "legal liability only" (pays only if the facility is negligent). Then ask for a certificate of insurance. A professional operator produces one on request without friction. While you're at it, call your own insurer: many agreed-value policies have storage provisions, and you want the two policies to overlap, not gap.
Operations: What Happens to the Car Between Visits
8. Battery tending as standard practice
Modern exotics are electronics platforms that happen to have wheels; a McLaren or a late-model 911 left unplugged can drain its battery in weeks, and deep discharge can mean fault codes, lost presets, or a dealer visit. Battery maintainers should be standard practice on every stored car, not an upsell — and you should see them in use on the tour: quality maintainers (not trickle chargers) connected to the cars on the floor, with cables routed cleanly. Ask how they handle cars with lithium batteries or battery disconnect procedures specified by the manufacturer.
9. Movement and exercise policy
Ask what happens to your car monthly. Some facilities offer scheduled exercise — starting the engine and bringing it to full operating temperature, or short drives to keep seals lubricated and prevent flat-spotting on tires. Others deliberately leave cars untouched unless instructed. Either policy can be right, but it should be a documented policy you choose, with a log of every start and every mile. "We start them when we get a chance" is the wrong answer; so is discovering unexplained mileage at pickup. Tire care matters here too: ask about inflation checks or tire cradles for long-term stays.
10. Transport logistics: enclosed carrier access and staging
If you buy at auction, ship to events, or move cars between homes, the facility becomes a logistics node. Check the physical realities: can a full-size enclosed transporter actually reach the door and load under cover, or does your car sit on a public street during transfer? Is there a staging area where cars can be prepped, inspected, and documented before loading? Facilities in busy collector markets handle this constantly — operators offering exotic car storage in Los Angeles often coordinate directly with transport companies, and a facility that receives carriers weekly will describe its intake process in detail, including condition photos on arrival.
People and Paperwork
11. Who actually touches the cars
Ask directly: who moves the vehicles, and what's their background? You want a small, named group of trained staff — not "whoever's on shift" — and you want to know whether the facility ever uses valets, porters, or third-party contractors to move cars. Ask about background checks, driving record reviews, and whether staff are trained on the quirks of low, wide, high-strung cars (nose lifts, cold-start protocols, single-clutch transmissions that hate creeping). The tour itself is evidence — watch how staff move around the cars already there.
12. Contract terms: access hours, liability, rate lock
Before you sign, read for three things. First, access: what hours can you retrieve your car, is appointment notice required, and is there a fee for access or for each in-and-out? Second, liability: what does the facility disclaim, what does it accept, and does the contract language match what the manager told you about insurance on the tour? Third, rate terms: is your monthly rate locked for a defined term, and how much notice does either side owe on termination or increases? Pricing varies widely by market and service level — our guide to what exotic car storage costs breaks down the ranges — but whatever the number, it should be in writing with the conditions attached.
Scoring the Tour
You don't need a facility to ace all twelve points — you need to know which ones it misses and whether those misses matter for your car and your climate. A facility with modest cameras but direct garagekeepers coverage and obsessive battery tending may serve you better than a showpiece with beautiful floors and a shared door code. Take notes, ask for the certificate of insurance, and trust the operators who answer fast and in specifics.
Better still, start with facilities that have already been checked against standards like these. Browse the city index to find verified exotic and classic car storage facilities near you, then bring this checklist to the tour.
