Garage keepers insurance, explained for specialty shops

Garage keepers insurance pays for damage to customers’ vehicles in your care, custody, and control. Garage keepers coverage comes in three forms that pay very differently — Legal Liability pays only if you were negligent, Direct Primary pays regardless of fault, and Direct Excess pays only after the customer’s own policy responds. The ISO endorsement most carriers build on writes Legal Liability as the default and makes the other two optional elections.

Then read the exclusions printed on that same form. Theft or conversion caused by your own employees is excluded, and so is faulty work you performed — the two scenarios a shop actually loses sleep over. Underneath all of it sits an older rule that decides most arguments: as a bailee, once the customer shows the car arrived fine and came back damaged, the burden shifts to you to show reasonable care. Coverage is the second question. Evidence is the first.

This is general information, not legal or insurance advice.

What is garage keepers insurance?

Garage keepers insurance is a commercial auto coverage that responds to damage to customers' vehicles while they are in your care, custody, and control — on the lot, in the bay, or being moved. It is distinct from garage liability, which covers your operations and premises, not the customer's car. Which form you buy decides whether a claim gets paid at all.

The distinction gets blurred in conversation because agents sell them together. Garage liability answers for bodily injury and property damage arising out of your operations. Garage keepers answers for the customer’s Model Y sitting in bay two. A tint shop with a general liability policy and no garage keepers line has, functionally, no coverage for the cars it holds (Insureon).

What is the difference between Legal Liability, Direct Primary, and Direct Excess?

Legal Liability pays only if the shop is found negligent, and can deny a theft claim outright if the insurer concludes the shop had adequate security. Direct Primary pays regardless of fault and costs more. Direct Excess pays only after the customer's own policy responds. Most disputes trace back to a shop that bought Legal Liability and assumed it bought Direct Primary.

Read your declarations page and find which of those three words is printed on it. Shops are frequently surprised (Intrepid Direct). The form itself settles which one you get by default: ISO’s Garagekeepers Coverage endorsement CA 99 37 10 01 writes Legal Liability as the standard grant and carries Excess and Primary as separate elections you have to ask for and pay for. Nobody upgrades you by accident.

How do garage keepers limits and deductibles actually work?

Limits are typically written per location, deductibles are owed per auto, and an aggregate caps the policy. In a single event that damages six cars, you can owe six deductibles. The working rule brokers give is to set the limit at the total value of every vehicle on your lot on your busiest day.

That last line is the one to act on. A five-bay PPF shop in December with three Model X, two Rivians, and a customer’s 911 waiting on film is carrying a lot value that has nothing to do with its revenue.

What limits do garage keepers programs actually offer?

They differ by orders of magnitude, so read the program rather than the category. Progressive states that most policies offer a maximum limit of $2,500 per occurrence, with a deductible that is typically $500, and sells garage keepers only packaged with garage liability and on-hook towing. NEXT Insurance's appetite guide writes garage keepers up to $100,000 — and excludes auto detailing from the garagekeepers endorsement entirely. Century Surety's garage program publishes $150,000 per auto, submit to $300,000, and $1,000,000 per location.

Now put a number on the other side. Mitchell’s 2025 year in review puts US repairable severity at $6,395 for a battery-electric vehicle against $5,105 for an internal combustion one (Mitchell). A PPF bay holding several Teslas overnight has six figures of other people’s property inside the fence, and a $2,500 per-occurrence limit is under 40% of one average BEV repair. The gap between the two Century numbers — per auto and per location — is the arithmetic every shop should do before renewal (Progressive, NEXT, Century Surety).

One correction while we are here, because the opposite is widely assumed: EVs are not written off more often. Mitchell reports an EV total loss rate of 7.25% against 8.49% for all internal combustion vehicles (Mitchell). The exposure a shop carries is severity per repair, not a higher chance of a write-off.

How much does garage keepers coverage cost?

Broker-published averages put garage keepers alone at roughly $1,000 to $1,300 per year, and a full garage package — liability plus garage keepers plus the rest — at roughly $3,000 to $8,000 per year. Your number moves with lot value, location, claims history, and the coverage form you pick.

Treat those as broker-published averages and nothing more; they are a sanity check on a quote, not a prediction. What moves the number most is lot value and claims history — which is exactly where custody discipline pays back.

What does one garage keepers claim cost at renewal?

More than the claim, and for several years. Century Surety publishes a loss-free credit of 0.95 for one year loss free, 0.90 for two years, and 0.85 for three. One claim resets that clock, so the verified swing is up to 15% of garage premium across the renewals that follow, on top of the per-auto deductible you already paid. Treat it as a schedule and judgment credit rather than a workers compensation style experience modifier — it is underwriter discretion, not a formula.

That is Century Surety’s own published schedule (Century Surety garage program). Add it up honestly: the deductible you pay on the claim, plus up to 15% of garage premium for the several renewals it takes to climb back to a three-year credit. A single scuff argument you cannot answer is not a one-year event.

What is commonly excluded?

The ISO Garagekeepers Coverage endorsement CA 99 37 10 01, the form most carriers build on, excludes loss due to theft or conversion caused in any way by you, your employees, or by your shareholders, and separately excludes faulty work you performed. Those are the two scenarios a shop actually fears — an employee drove it, and we damaged it doing the job — and they are the two the standard form most plausibly excludes. Said plainly: the shop, not the carrier, frequently eats those losses.

The endorsement is public and the language is short. Under C. Exclusions 1. of ISO form CA 99 37 10 01:

Sit with what those two cover. An employee drove it is the first one. We damaged it doing the job is the second one. Those are not exotic edge cases — they are the two scenarios a shop owner names when you ask what keeps them up, and the standard form is the most likely place both of them stop. The implication has to be stated plainly rather than buried: in those events the shop, not the carrier, frequently eats the loss (CA 99 37 10 01).

Which reframes what a custody record is for. If the carrier is not going to answer for an employee’s unauthorized drive, then the only thing standing between that event and your own checkbook is whether you can tell — early, and with dates — that it happened at all.

Who has the burden of proof if a customer car is damaged?

Under bailment law, a shop holding a customer's car is a bailee with a duty of reasonable care. Once the customer shows the car was delivered undamaged and returned damaged, the pattern jury instructions in New Jersey, Wisconsin, and Colorado all raise a presumption of negligence and hand the shop the burden of coming forward with evidence that it was not negligent. A shop with no record starts that argument already losing.

Bailment is old, boring, and decisive, and three states publish the rule in the words a jury actually hears. New Jersey states it in Model Civil Jury Charge 4.41 (njcourts.gov). Wisconsin states it in JI-Civil 1025.7 (wilawlibrary.gov). Colorado states it in CJI-Civ. 16:6, titled, with no ambiguity at all, “Failure of Bailee to Return Property or Return It in Undamaged Condition — Presumption of Negligence” (coloradojudicial.gov).

A presumption of negligence arises when the bailor establishes that the bailed property was damaged while in the possession of the bailee. The bailee then has the burden of going forward with evidence to show that he or she was not negligen[t].
— Wisconsin JI-Civil 1025.7

Colorado supplies the consequence. That chapter, citing Krueger v. Ary, explains that when a rebuttable presumption goes unrebutted, “the presumed fact is established as a matter of law.” Rebutting takes evidence, and evidence means a record. This is the whole thesis of this guide, and it needs no statistic to carry it: a shop with no record starts the argument already losing. “We do not think anyone drove it” is not a record. A plain-English explainer of the underlying doctrine sits at UpCounsel.

How often are customer cars damaged or stolen at repair shops?

Nobody publishes that number, and we are not going to invent one. Garage keepers is not a separate NAIC statutory line — it sits inside commercial auto physical damage — so there is no premium or loss series to read. No public dataset reports how often customer vehicles are damaged, stolen, or driven without authorization at repair, detail, or valet businesses. A CourtListener API search returns only 38 US opinions since 2015 that mention garagekeepers at all, which counts published appellate writing rather than incidents. What can be stated is the legal posture, the exclusions printed on the form, and the limits math.

We went looking for the number a page like this is supposed to open with, and it is not there. Garage keepers is not broken out as a statutory line in NAIC reporting — it sits inside commercial auto physical damage — so there is no premium or loss series to read against it. No public dataset counts customer vehicles damaged, stolen, or driven without authorization at repair, detail, or valet businesses. A CourtListener API search returns 38 US opinions since 2015 that mention garagekeepers at all, and that is a count of published appellate writing, not of incidents.

So this guide quotes no frequency figure, and you should be wary of pages that do. What can be sourced is everything above: the legal posture, the exclusions printed on the form, and the limits math. Those decide the outcome of one case at a time, which is the only kind of case you will ever be in.

What do garage keepers underwriters actually ask about?

Physical security and driver quality. Admiral's garagekeepers legal liability application asks about CCTV, alarms, lighting, guards, a key lockbox, a written customer contract, and posted signs. Argo's garage application asks whether you always ride along on test drives, how you verify a driver's license, whether vehicles go out overnight, and how keys are stored. CRC's garage application rates window tint as a percentage of your work mix and lists valet and parking as a business type. None of them rate a documentation system, and no carrier in this class publishes a credit for keeping custody records.

Read that list for what is missing from it. Underwriters in this class rate fences, cameras, key cabinets, and driving records — physical security and driver quality. Not one of them rates a documentation system, and no carrier here publishes a credit for keeping custody records. We would rather write that down than imply a discount that does not exist. A custody file changes what happens after a claim, not what you pay before one.

What documentation does an insurer actually want?

Intake condition evidence, timestamped, from before the work started, plus a clear record of who had custody and what moved. Broker guidance is explicit on this: intake documentation is what establishes which damage was pre-existing, and that matters most when coverage turns on negligence.

Thorough intake documentation helps establish what damage was pre-existing, which is critical when coverage depends on negligence.
— Intrepid Direct

Note the conditional in that sentence. If you bought Legal Liability, your intake photos are not paperwork — they are the coverage trigger. The corresponding movement question (did the car leave the lot, how far, when) is covered in the guide on customer cars damaged at a shop.
