Garage liability vs garage keepers

This is general information, not legal or insurance advice. Forms vary by carrier and by state, and the only form that governs your claim is the one attached to your policy.

That is the sentence the whole distinction rests on. It is not a limitation buried in an endorsement or a carrier’s house wording — it is a numbered exclusion in the liability section of the standard form, and it removes the customer’s car before anyone asks whether the shop was at fault.

What is the difference between garage liability and garage keepers insurance?

Garage liability answers for injury and damage your operations cause to other people and their property. Garage keepers answers for damage to the customer's vehicle you are holding. They are not competing products — the second exists because the first is written to exclude it. In ISO's Business Auto Coverage Form CA 00 01, the Care, Custody Or Control exclusion at Section II.B.6 removes property damage involving property owned or transported by the insured or in the insured's care, custody or control. A customer's car in bay two is property in your care, custody or control, so the liability side stops at the edge of your own lot. The Garagekeepers Coverage endorsement CA 99 37 is the instrument that puts it back, and it does so on its own terms: its own limit, its own deductible, its own exclusions, and only at the locations listed on its schedule.

The exclusion is the mechanism, not a technicality

Shops tend to read the two coverages as a product decision — the basic one and the upgrade. The forms describe something else: a deliberate hand-off between two documents, where the first says what it will not do and the second exists to do it.

• The liability side takes the car out. CA 00 01 Section II.B.6 excludes property damage involving property “owned or transported by the ‘insured’ or in the ‘insured’s’ care, custody or control” (independentagent.com). The one carve-out is liability assumed under a sidetrack agreement — a railroad siding provision that will never apply to a body shop. Note how broad the rest is: it is not limited to cars, and it is not limited to negligence.
• The endorsement puts the car back. CA 99 37 agrees to pay “all sums the ‘insured’ legally must pay as damages for ‘loss’ to a ‘customer’s auto’ or ‘customer’s auto’ equipment left in the ‘insured’s’ care while the ‘insured’ is attending, servicing, repairing, parking or storing it” in your garage operations (independentagent.com).
• It attaches to a policy rather than replacing one. The endorsement’s own opening states that it modifies insurance provided under the Business Auto, Motor Carrier and Truckers coverage forms, and that “with respect to coverage provided by this endorsement, the provisions of the Coverage Form apply unless modified by the endorsement.” So the underlying policy still supplies the conditions — including the duties after a loss, which the endorsement does not modify.

The definitions do the rest of the work. CA 99 37 defines a customer’s auto to include “any customer’s auto while left with you for service, repair, storage or safekeeping,” and — a detail worth catching — states that “customers include your ‘employees’, and members of their households who pay for services performed.” The staff car being fixed on a Saturday is a customer’s auto if someone paid for the work. Garage operations is defined to cover the locations used for selling, servicing, repairing, parking or storing customer autos “and that portion of the roads or other accesses that adjoin these locations”, which is how a car damaged while being backed across the street to the overflow lot stays inside the grant.

Which coverage pays when a customer's car is damaged at my shop?

Garage keepers, if you bought it and the loss is not excluded. The endorsement pays all sums the insured legally must pay as damages for loss to a customer's auto or customer's auto equipment left in the insured's care while the insured is attending, servicing, repairing, parking or storing it in your garage operations. Garage liability does not reach that loss at all, because the care, custody or control exclusion removed it before the question of fault ever came up. This is the most expensive misunderstanding in shop insurance: a shop with a large liability limit and no garagekeepers endorsement has no coverage for the cars on its own lot, and the size of the liability limit makes no difference to that.

Do I need both garage liability and garage keepers?

If you hold customers' vehicles, yes — they cover different halves and neither substitutes for the other. Garage keepers is an endorsement rather than a policy: CA 99 37 states that it modifies insurance provided under the Business Auto, Motor Carrier and Truckers coverage forms, and that with respect to coverage provided by the endorsement, the provisions of the coverage form apply unless modified by the endorsement. There has to be a policy underneath for it to attach to. The common failure is not a shop that bought one and skipped the other; it is a shop that bought a package, assumed the customer-car half came with it, and never read the schedule.

Why does garage liability exclude the customer's car?

Because liability insurance is priced for the risk of harming strangers, and property you voluntarily take possession of is a different risk with different economics. A shop chooses which cars to accept, how many, how long to hold them and how to secure them, and it is paid for holding them. Insurers underwrite that exposure separately — by location, by limit, and with its own deductible — rather than letting it ride on a liability limit sized for a collision on a test drive. The exclusion in CA 00 01 is deliberately broad: it removes property owned or transported by the insured as well as property in the insured's care, custody or control, with one narrow exception for liability assumed under a sidetrack agreement, which is a railroad siding provision that will never apply to a body shop.

Does garage keepers cover everything garage liability leaves out?

No, and the gaps are named in the endorsement itself. CA 99 37 Section C excludes liability resulting from any agreement by which the insured accepts responsibility for loss; loss due to theft or conversion caused in any way by you, your employees or your shareholders; defective parts or materials; and faulty work you performed — with work you performed defined to include work someone performed on your behalf and the providing of, or failure to provide, warnings or instructions. A customer's car damaged by your own bad repair is a faulty-work loss, not a garage keepers loss. A car taken by your own technician is excluded outright. And a promise written into your own intake paperwork can move a loss into the contractual-obligations exclusion by itself.

Two of those four are worth sitting with, because they are the ones that turn a shop’s own conduct into the reason a claim fails. The theft exclusion removes loss “due to theft or conversion caused in any way by you, your ‘employees’ or by your shareholders” — so the identity of whoever last had the vehicle decides the claim as much as the damage does. The faulty-work exclusion is broader than it first reads, because the endorsement defines work you performed to include “work that someone performed on your behalf” — a sublet alignment or a subcontracted glass job is still your work for this purpose.

Is garage keepers coverage automatic at every location I operate?

No. CA 99 37 opens by stating that the endorsement provides only those coverages where a limit of insurance and a premium are shown for that coverage in the schedule, and only for the location shown in the schedule. Three things follow from that sentence. Coverage is per location, so a second building, an overflow lot or a storage yard is uncovered unless someone added it. Coverage is also per coverage type — comprehensive, specified causes of loss, and collision each need their own limit and premium, so a policy can answer for a hailstorm and not for a car rolled into a pillar. And the direct coverage options are printed as checkboxes: if neither EXCESS INSURANCE nor PRIMARY INSURANCE is marked, the endorsement stays on a legal liability basis and pays only when you are legally liable.

The endorsement also carries a short list of property it will not pay for at all, and that list is a useful reminder of how old the form is: sound reproducing equipment unless permanently installed, tapes and records, citizens’ band and two-way radios and scanners unless installed in the opening the manufacturer left for a radio, and radar or laser detectors and jammers. It was drafted in 2001. Nothing in it contemplates a vehicle whose infotainment, drive credentials and trip history are part of the car itself — which is a gap shops running late-model EVs should raise with a broker rather than assume away.

Is it garagekeepers or garage keepers?

ISO writes it as one word — the endorsement is titled Garagekeepers Coverage — while brokers, carriers and state filings use garage keepers, garagekeepers and garage keeper's more or less interchangeably, and abbreviate the legal liability version GKLL. Nothing turns on the spelling. What does turn on wording is the difference between garage liability and garage keepers, which sound like two names for one product and are two different coverages with two different triggers.

Where the argument actually ends up

Sorting out which form applies is the first half. The second half is proof, and it runs on a different track entirely. Garage keepers written on the default legal liability basis pays only when the shop is legally liable — and in a bailment, the customer who shows the car was delivered undamaged and came back damaged shifts the burden onto the shop to come forward with evidence that it was not negligent. That is the position the pattern jury instructions describe, and it is the reason a coverage question so often turns into a documentation question. The guide on a damaged customer car covers the burden and the reported cases; the garage keepers guide covers limits, deductibles and what one claim does at renewal.

The two elections that change this are the checkboxes on the schedule. Direct Primary pays without regard to legal liability. Direct Excess pays without regard to legal liability but only over other collectible insurance, which pulls your customer’s own policy in first. If neither box is checked, you have neither.
