What insurance does a detailing business actually need?
A solo mobile detailer with no employees should budget roughly $3,000–$3,500/year for general liability, garagekeepers, and commercial auto combined. A small shop with 2–3 employees runs closer to $8,000–$9,000/year once workers' compensation and shop-vehicle coverage are added. Four coverages make up almost the entire picture: general liability (third-party injury/property damage from your operations), garagekeepers liability (the customer's vehicle itself, while it's in your care), commercial auto (any vehicle used for business, including "just driving to jobs"), and workers' compensation (legally required in most states once you have employees).
The single most common budgeting mistake is assuming general liability covers vehicle damage. It doesn't — that's a completely separate policy, and it's the one most new detailers skip.
General liability insurance: what it covers and what it costs
Auto detailing and car wash businesses pay an average of $54/month ($646/year) for general liability insurance, based on standard limits of $1 million per occurrence and $2 million aggregate. General liability covers third-party bodily injury and property damage caused by your business operations — a customer slipping on a wet driveway, your pressure washer cracking a window, a chemical spill damaging a client's patio.
What it does not cover: damage to the vehicle you're actually working on. That's a coverage gap by design, not an oversight — vehicles in your care fall under a different policy entirely.
Garagekeepers legal liability: the coverage most new detailers skip
Garagekeepers liability covers the customer's vehicle itself while it's in your care, custody, or control — a rotary buffer burning through clear coat, a steamer damaging a screen, chemicals bleeding into leather, a ding while repositioning a car for the next stage. Expect to pay $800–$2,000/year, averaging $1,000–$1,300/year for $75,000 in limits with $250–$500 deductibles.
This is also the coverage commercial and fleet clients ask for by name before they'll sign anything — if you've priced out a fleet detailing contract, assume the client's insurance requirement includes proof of garagekeepers, not just general liability.
Commercial auto insurance for mobile detailers
Personal auto insurance almost universally excludes business use, and insurers can — and do — deny a claim after the fact once they discover the vehicle was being used commercially. Mobile detailing vans commonly run $100–$250/month; the broader commercial van average is $189/month ($2,272/year) for minimum coverage, ranging $95–$362/month depending on vehicle, coverage limits, and driving record.
Location moves this number a lot: urban high-cost states like New York ($249/mo), California ($238/mo), and Florida ($269/mo) run well above lower-density states like Iowa ($111/mo), Idaho ($120/mo), and Wisconsin ($138/mo). Commercial auto rates have also risen 8–10% recently in higher-cost states, driven by auto-parts tariffs and rising repair costs — a reason to re-shop this policy at renewal instead of auto-renewing.
Workers' compensation: when you actually need it
Most states require workers' comp starting with your first employee, full- or part-time. A handful of states set the threshold at 3 or more employees. Texas is the only state where it's fully optional for private employers. Cost averages $113 per employee per month ($1,354/year) across industries, though the real range runs $16–$343/employee/month depending on state and risk classification — detailing typically sits toward the lower end of that range, but confirm your specific classification rather than assuming.
Bundling into one policy: BOP vs. buying separately
A Business Owner's Policy (BOP) bundles general liability with commercial property coverage for an average of $89/month ($1,073/year) — cheaper than buying the two separately. A Commercial Package Policy (CPP) averages $71/month ($850/year) and can usually have garagekeepers added as an endorsement on the same policy. For most solo and small-shop operators, getting a BOP or CPP quote from 2–3 carriers that specifically write detailing/car-wash policies and adding garagekeepers plus commercial auto as endorsements is cheaper than four standalone policies.
Do you need a business license bond too?
Most states require nothing detailing-specific beyond a general business license, a seller's permit if your state taxes the service, and proof of insurance. The exception: a few states specifically regulate car washing/mobile detailing with a surety bond requirement. California and New York both require a $150,000 bond for licensed operators — but both exempt a solo operator with zero employees from the state-level bond and license (a local business license is still typically required). Bond premiums run 1–10% of the bond face amount, so a $150,000 bond costs $1,500–$15,000/year if it applies to you. State requirements vary — check your state's page at detailflowpro.com/regulations before assuming either way.
A worked budget: solo mobile operator vs. a 3-employee shop
Solo mobile, no employees: general liability ($646) + garagekeepers ($1,000) + commercial auto ($1,800 mid-range) = ~$3,450/year, no workers' comp required.
Shop with 3 employees: BOP bundling GL + property ($1,073) + garagekeepers ($1,300) + commercial auto for one shop vehicle ($2,272) + workers' comp for 3 employees (~$1,354 × 3 = $4,062) = ~$8,700/year.

Common mistakes that cost more than the premium would have
The same handful of gaps show up again and again once a detailer has an actual claim:
- Skipping garagekeepers because "general liability should cover it." It doesn't — a single high-end vehicle damage claim ($5,000–$50,000+ on a luxury or exotic car) with no garagekeepers coverage comes entirely out of pocket.
- Driving on a personal auto policy for a "just driving to jobs" mobile setup. Insurers can and do deny claims once commercial use is discovered — leaving you fully exposed on exactly the kind of accident insurance exists for.
- Signing a fleet or commercial contract before confirming the client's insurance minimums. Many commercial and property-management clients require $1M+ general liability and proof of garagekeepers before day one — confirm this before you finalize the pricing.
- Letting coverage lapse mid-contract to save a renewal premium. A lapsed policy discovered by a fleet client is grounds for contract termination in most commercial agreements.
