Insurance for an auto repair shop: costs, coverage and exclusions
Auto repair shop business insurance costs turn on payroll, car count and the work you do, and the exclusions decide what a claim actually pays.
What to take away
- Insurance for an auto repair shop has two core linesgarage liability and garagekeepers. Garage liability covers the business. Garagekeepers covers customer cars in your care.
- Workers compensation is priced on payroll by class code. In NCCI states, repair shops often fall under class 8380, automobile service or repair center. Technician wages drive that premium more than any other input.
- General liability excludes the vehicle itself and the work you performed. A botched repair is a garagekeepers or warranty claim, not a slip-and-fall claim.
- Every policy carries a care, custody and control exclusion. Garagekeepers is the endorsement that buys that exposure back.
- Costs vary by state, payroll and the value of cars you hold overnight. The table below lists typical 2026 ranges by line. Ask your carrier or a licensed broker for rates in your state. No national figure survives contact with a single ZIP code.
This article is general business information, not insurance, legal, tax or repair advice. Coverage forms, limits and state filing rules vary. Read your own policy and confirm anything you plan to rely on with your carrier or a licensed broker. The Shop licensing rules and compliance filings behind them vary by state and municipality too.
Garage liability and garagekeepers
Garage liability is the base policy for the business. It answers for customer injuries in the waiting area and for damage you cause away from the shop. Landlords and dealer referral agreements usually ask to see a certificate before they will sign.
Garage Liability vs Garagekeepers
Garage liability
- What it covers
- Customer injury, premises
- Typical annual cost
- $1,200 to $6,000
- Limits basis
- Payroll, revenue, limits
- Who asks for it
- Landlords, dealer referrals
Garagekeepers
- What it covers
- Customer cars in your care
- Typical annual cost
- $750 to $2,500
- Limits basis
- $100,000 to $250,000
- Who asks for it
- Vehicle value on lot
Payroll, revenue and the limits you choose drive its price. Those three numbers are what your broker needs before quoting.
Garagekeepers answers for customer vehicles while they sit in your care, custody and control. It pays when a car is damaged on the lot, stolen overnight, or hurt by a fire or a failed lift. The limit you need follows the value of the cars you hold overnight, not the value of your own equipment.
Two forms exist: legal liability, which pays only when you are legally on the hook, and direct, which pays regardless of fault.
Direct costs more and ends arguments faster.
Coverage, exclusions and cost by line
| Line | What it pays for | What it excludes | Typical annual cost as of 2026 |
|---|---|---|---|
| Garage liability | Customer injury, premises damage, off-site operations | The customer's vehicle, your faulty work | $1,200 to $6,000 for one location |
| Garagekeepers | Customer cars in your care, theft, fire, lot damage | Vehicles you own, employee cars | $750 to $2,500 for $100,000 to $250,000 in limits |
| Commercial property | Building, lifts, tools, parts inventory | Customer vehicles, wear and tear | $0.40 to $1.50 per $100 of insured value |
| Workers compensation | Employee injury and lost wages | Owner-only shops in some states | $1.20 to $8 per $100 of payroll by state class |
| Commercial auto | Shop trucks, tow vehicles, loaner cars | Customer cars you are road-testing | $1,200 to $4,000 per vehicle |
| Umbrella | Claims above the underlying limits | Anything the base policy already excludes | $750 to $2,500 for a $1 million limit |
| Pollution liability | Fuel, oil, solvent and refrigerant releases | Standard policies exclude these | $750 to $3,500 with waste oil or A/C service |
The pattern in that table is the one owners get wrong. General liability and property cover what you own. Garagekeepers and commercial auto cover what you move.

What the exclusions look like in practice
Care, custody and control. Every general liability policy excludes property in your care. A car on your lot is in your care. The general liability policy steps aside, and garagekeepers answers.
Buy garagekeepers on two numbers, the limit and the deductible. The per-vehicle limit should sit at or above the highest-value car you expect to hold overnight, and the aggregate should cover the ordinary mix on the lot. A $90,000 truck with a $50,000 per-vehicle limit leaves a $40,000 gap the shop pays itself.
Set the deductible at the largest amount you can pay from cash without touching the operating account. Check whether it applies per vehicle or per loss before you sign.
Your work and your product. Faulty workmanship is excluded from general liability. If a repair fails and damages something else, the claim runs through garagekeepers or through the parts and labor warranty you gave the customer. This is the exclusion behind most comeback disputes.
Road testing and employee use. A technician driving a customer car is usually covered under garagekeepers. A shop-owned truck or loaner needs commercial auto. Confirm which policy answers before a road test turns into a claim.
Pollution. Fuel, oil, solvent and refrigerant releases are excluded from standard policies. If you store waste oil or run an A/C service bay, ask about a pollution endorsement. The EPA's automotive sector requirements and its refrigerant handling rules set the federal floor your carrier will ask about.
How the premium is built
Insurers price a repair shop on several factors. Payroll by class code, car count, average repair order, whether you do bodywork or towing, and your loss history all move the number. A shop writing $1,200 average repair orders pays more than one writing $400 tickets at the same car count.
The arithmetic is simple enough to run yourself. Take your annual technician payroll, multiply by the workers compensation rate your state assigns to your class code, and add the garage liability base. Add garagekeepers as a percentage of the value of cars you typically hold overnight.
Two variables decide most of it: annual payroll and highest vehicle value on the lot. Everything else is a modifier. Your state's assigned rate is published by its insurance department or rating bureau. NCCI lists class code 8380 for automobile service or repair centers in NCCI states. A broker will quote it in an afternoon.
California is the clearest contrast. The state does not use NCCI. The WCIRB publishes advisory pure premium rates by class code, and each insurer files its own rate against them. Texas publishes NCCI loss costs, and carriers add their own multipliers. The same payroll can price very differently in the two states.
How each line prices for a small shop:
- Workers compensation
- per $100 of payroll, set by the state rate for your class code and your claims history.
- Garage liability
- on payroll, revenue and the limits you select.
- Garagekeepers
- on the value of the cars you hold overnight and the limit you set.
- Commercial property
- per $100 of insured value for the building, lifts, tools and parts.
- Commercial auto
- per vehicle, by driver record and radius of operation.
- Umbrella
- on the underlying limits and the number of vehicles and locations.
- Pollution liability
- on whether you store waste oil or run an A/C service bay.
The table above carries the typical 2026 cost ranges by line. Those are typical ranges, not quotes. Your state, limits, deductibles and loss history move them. A broker can bind coverage the same week.
Where safety records change the price
A shop with a documented safety program pays less than one without. OSHA's safety management guidance describes the find-and-fix approach carriers reward: inspect, correct, record, repeat. Lift inspections, eye protection, ventilation and chemical handling all feed the same file.
That file does double duty. It lowers the workers compensation modifier, and it is the first thing a carrier asks for after a claim. Keep it current, and keep it separate from the customer-facing side of the business.
Carriers may apply a schedule credit for a documented program at renewal. The size depends on the carrier and state. A clean three-year loss run helps too.
Fitting the premium into the month
Insurance is a fixed line the month has to clear before a bay earns anything. It belongs in the same calculation as rent and software, not in a folder labeled overhead. Profit margins and break-even points shows where that line lands per bay.
Review the policy at renewal, not after a loss. Car count, payroll and the cars you hold overnight all drift during a year. A limit set two years ago may no longer match what sits on the lot tonight.
A shop paying $12,000 a year across those lines carries about $1,000 a month in fixed insurance cost.
When 2027 rates land
No 2027 rate is public yet, so the figures in this article are the 2026 ones. Your 2027 renewal will reprice at your policy anniversary, using the payroll, car count and lot values from the year just ended.
State rate filings land on set dates, and the date depends on the state and the rating bureau. Ask your broker which filing applies to your class code before you budget the year.
Common questions
What does insurance for an auto repair shop cost?
Every line prices on a different base, from payroll for workers compensation to vehicle values for garagekeepers. Typical 2026 ranges for a small shop are in the table above. Your state rate filing, your limits and your loss history move each one.
Does garagekeepers cover a customer car stolen from the lot?
Usually yes, if the policy is in force and the car was in your care. Legal liability forms may require you to be legally responsible first. Direct forms pay regardless of fault. Check which form you hold before you need it.
Is a road test covered?
A technician driving a customer car is normally covered under garagekeepers. A shop-owned truck, tow rig or loaner car needs commercial auto. Confirm the split with your carrier in writing.
Why did my premium rise with no claims?
Workers compensation rates reset by state filing, and carriers reprice every line at renewal. Ask the broker to show which variable moved on your policy.
Does general liability pay for a comeback repair?
No. Faulty workmanship is excluded, and the vehicle is excluded as property in your care. The claim runs through garagekeepers or the warranty you gave the customer.
