Mobile detailing insurance usually means general liability plus an auto policy, either commercial auto or hired and non-owned auto. Add coverage for client cars in your care, such as garagekeepers. General liability usually excludes property in your care, custody, or control. Insureon puts the 2025 median general liability premium for detailers and car washes at $54 a month.
The SBA says laws requiring insurance vary by state. Your services, vehicles, helpers, and contracts set the rest. Fill in the mobile detailing insurance broker worksheet as you read, then take it to a licensed broker or agent.
What insurance do mobile detailers need?
A mobile detailer usually needs three policies. General liability usually responds to injuries and damage to other people. The auto policy must fit who owns the vehicle. Client-car coverage handles the car you work on.
Add tools coverage when the kit rides in the van. Add workers compensation when a helper joins, under your state's rules.
Six common mobile incidents map to the policy that usually responds. Policy wording decides each row, so each row carries a question for the broker.
| Incident | Policy that usually responds | Exclusion or question to ask |
|---|---|---|
| Polisher burns paint, or a chemical stains trim, on the client's car | Garagekeepers coverage or a care, custody, or control endorsement (Simply Business) | Does the coverage apply at the client's home or workplace? Does it cover a workmanship error? |
| A customer trips over your hose at the job | General liability, which SBA says covers bodily injury, medical expenses, and defense costs | What are the per-occurrence limit, the aggregate limit, and the deductible? |
| You crash while driving to a job | Commercial auto for a business vehicle. Hired and non-owned auto for rented or employee cars (The Hartford). | Progressive Commercial says personal auto often does not cover business use. Does the policy pay for your own vehicle or only for harm to others? |
| An extractor is stolen from the van | Inland marine or tools and equipment coverage (Progressive Commercial) | Is theft from a locked vehicle covered, and overnight storage? What is the per-item sublimit? Bolted-in equipment may fall under commercial auto. |
| A helper is injured on a job | Workers compensation (Progressive Commercial; California Department of Insurance) | When does your state require it for your helpers? Ask your state workers compensation agency. |
| A neighbor complains about wash water or chemical runoff | Usually none under general liability. The California Department of Insurance lists pollution as a major exclusion. | Is any pollution coverage available? Confirm runoff rules with your local stormwater authority. |
Does general liability cover a client's car?
Usually no. The California Department of Insurance lists care, custody, or control among the major general liability exclusions. IRMI says that exclusion "eliminates coverage with respect to damage to property in the insured's care, custody, or control." A client car you are washing or polishing sits in your care.
Simply Business addresses workmanship errors, such as burning paint with a polisher. It says you typically need garagekeepers primary coverage or a care, custody, or control endorsement. IRMI says auto businesses other than dealers get garagekeepers coverage through the Garagekeepers Coverage (CA 99 37) endorsement.
Progressive Commercial describes garagekeepers legal liability as protection for customer vehicles parked, serviced, or stored at your business. Ask whether a customer's driveway or workplace counts as a covered location. Progressive Commercial also names bailee's customer insurance, an inland marine form, as another way to close the gap.
Put three more client-car questions on the worksheet:
- Are items inside the car, such as a child seat, included?
- Is a car kept overnight covered, and where?
- Is settlement actual cash value or replacement cost, and what is the deductible?
How much does mobile detailing insurance cost?
Four publishers put general liability at or under $79 a month, and each figure rests on a different basis. Compare a figure only with its publisher, basis, and year in view. Do not average them. Your own quote replaces all of them.
| Coverage | Figure | Publisher and basis | Year |
|---|---|---|---|
| General liability | $54 a month ($646 a year), $1 million per occurrence and $2 million aggregate | Insureon: median of policies for car washes and auto detailers who apply for quotes | 2025 |
| General liability | From $17.92 a month | Simply Business: 10th percentile of relevant policies sold by Simply Business, July to December 2025 | 2025 |
| General liability | $55 a month median, $79 a month average | Progressive Commercial: new customers, all industries | 2025 |
| Stand-alone general liability | $810 a year, about $68 a month | The Hartford: average for its small business customers. It does not offer coverage for detailers and says the amounts can help estimate costs. | Page updated 2026 |
| Business owner's policy (BOP) | $1,687 a year, about $141 a month | The Hartford: same small business customer average | Page updated 2026 |
| Garage keepers | $38 a month ($458 a year), $1 million per occurrence, $2 million aggregate, $500 deductible | Insureon: median of policies bought by its auto service customers, all auto service businesses | 2025 |
| Commercial auto | $46 a month ($550 a year) | Insureon: median for car washes and auto detailers who apply for quotes | 2025 |
| Business auto | $207 a month median, $276 a month average | Progressive Commercial: new policies, per vehicle, liability and physical damage, no violations | 2025 |
The two auto figures conflict because they measure different groups. Insureon counts detailers and car washes who applied for quotes. Progressive Commercial counts new business auto policies per vehicle with no violations. Treat the pair as a wide range and price your own vehicle.
Insureon says limits, deductibles, services, equipment value, location, revenue, and employee count all move the premium.
Insurance is fixed overhead. Enter the monthly premium total in the cost-per-detail calculator to see what it adds to each job.
Worked example: premium per job and a tool sublimit (hypothetical)
Inputs: $150 a month in total premiums, 30 jobs a month, a $6,000 tools limit, a $1,200 per-item sublimit, and a $500 deductible. These inputs are hypothetical. Replace each one with your own quote.
- Premium per job: $150 / 30 jobs = $5 per job.
- A stolen polisher is worth $1,500.
- Deductible after the sublimit: $1,200 - $500 = $700 payout. Uncovered loss: $1,500 - $700 = $800.
- Deductible off the loss first: $1,500 - $500 = $1,000 payout, under the sublimit. Uncovered loss: $500.
Result: the payout stays under the $6,000 limit in both orders. The deductible order moves the payout by $300. Record which order each quote uses.
Do you need insurance for mobile detailing?
You need some insurance once you have employees. SBA says the federal government requires every business with employees to have workers' compensation, unemployment, and disability insurance. SBA adds that some states also require additional insurance. A customer contract can add its own requirements.
Run a coverage check on your operation. Each line needs an answer from a broker.
- Pass: every activity on the worksheet has a named policy, a limit, a deductible, and a written answer.
- Fail: any activity lacks a named policy or has only a verbal answer. Treat that activity as uncovered until the broker confirms it in writing. Rerun the check.
Rerun it after a new vehicle, a first hire, a new service, overnight storage, or a new contract. The first paid detail checklist also says to accept only work within your insurance.
Tax treatment of premiums
IRS Publication 334 lists liability insurance among the business premiums you can generally deduct. It also lists insurance on vehicles used in your business. For a vehicle with personal use, deduct only the business-use share of the premium.
The mileage method changes the auto line. Publication 334 says: "If you use the standard mileage rate to figure your car expenses, you can’t deduct any car insurance premiums." Confirm the treatment for your return with a qualified tax professional.
Common questions
What insurance do I need as a detailer?
A solo detailer driving to jobs starts with general liability, the right auto policy, and client-car coverage. Tools coverage follows the kit into the van. Workers compensation comes with the first helper, under state rules. A contract may add a certificate or additional insured requirement, so read it with your broker.
How much is $1,000,000 liability insurance a month?
Insureon puts the median at $54 a month for a $1 million per-occurrence general liability policy for auto detailers and car washes. That figure also carries a $2 million aggregate limit. Other publishers' figures sit in the cost section with their basis. Your services, location, limits, and deductible set your price.
What does garagekeepers coverage insure against?
Garagekeepers coverage insures damage to customer vehicles in your care. Progressive Commercial names fire, theft, vandalism, and collision for vehicles parked, serviced, or stored at your business. IRMI says non-dealer auto businesses add it by endorsement. Confirm whether it applies at a customer's driveway and to workmanship errors.
How much is garage keepers liability insurance?
Insureon puts the median garage keepers premium for auto service businesses at $38 a month, or $458 a year (2025). That median policy has $1 million per occurrence and $2 million aggregate limits and a $500 deductible. It covers all auto service businesses, so a detailer's price can differ. Get client-car coverage priced as its own line on each quote.
Do I need an LLC to get general liability insurance?
No. SBA's insurance table lists general liability under "Any business." SBA says an LLC protects personal assets in most instances, and a sole proprietor can be held personally liable for business debts. Pick a structure with the steps to start a detailing business.
