How to start a car detailing business in 2026

Mobile or a bay first? Mobile means no rent and a selling point for busy owners, and it's how most of the owners quoted below started — one in Minnesota who says “Everything is ready to go in the van” (The Globe, May 2023), one in Massachusetts who added a trailer with a water tank and generator so he could work in apartment parking lots (WJAR, October 2026). A bay means rain-proof days and the controlled light that paint correction and coatings need; one Minnesota owner who moved from a private garage to a storefront says the change was "efficiency and visibility" (New Ulm Journal, April 2026), and one California owner raised prices $25 to $50 a service after moving into a fixed location (Housecall Pro's customer story, October 2025). Start mobile with daily drivers, learn the paint, and move into a bay once the calendar can pay the rent.

The kit, and what it costs. Housecall Pro's start guide puts a basic mobile kit at $800 to $1,500, an intermediate one at $2,000 to $5,000 and a professional one at $5,000 to $15,000, with a pressure washer at $500 to $1,300, a professional vacuum at $200 to $600 and products at $300 to $500 (Housecall Pro, September 2026); Detail King's blog says $1,500 to $3,000 part-time, $5,000 to $10,000 mobile and $10,000 to $25,000 or more for a shop (Detail King, September 2025). The dealers' own prices, seen October 2026: a Griot's Garage G9 dual-action polisher is $179.99 (Griot's Garage); Harbor Freight's Bauer 8-millimeter polisher is $64.99 and its 20-millimeter long-throw $79.99 (Harbor Freight; Harbor Freight), its 9-gallon wet/dry vacuum $79.99 (Harbor Freight), its 1,800 PSI electric pressure washer $99.99 and its 2,000 PSI $189.99 (Harbor Freight; Harbor Freight), a foam cannon $34.99 (Harbor Freight) and a 3,500-watt inverter generator $799.99 (Harbor Freight); a Mytee Lite III heated carpet extractor is $1,475 at Detail King (Detail King); a 100-gallon water tank is $459.95 and a 150-gallon $649.95 — "a typical full exterior wash uses 10 to 15 gallons per vehicle" (Detail King; Detail King); a 50-milliliter CarPro Cquartz UK 3.0 coating kit is $79.99, rated for two to five years at about 10 milliliters a coat (CarPro); and Detail King's complete start-up kit — two Rupes polishers, the Mytee extractor, a Tornador, a foam cannon and chemicals for 35 to 40 vehicles, no pressure washer, tank or generator — is $5,226 (Detail King, October 2026). Buy the polisher and the extractor you'll use for a thousand hours; everything else can be the cheap one at first.

How to price: by package and by vehicle size. Every menu above does it the same way: three packages, a price for a sedan and higher ones for an SUV, a truck and a van, add-ons priced separately (pet hair, odor, headlights, engine bay), and the coating as its own quote. Set the package from the hours it takes — Centex Mobile Detailing prints "2–4 hours" for a full detail (Centex) — and time every job for the first month. Write it down before the first car: our free car detailing checklist is what each package includes, in the order the work is done, and the vehicle inspection form is the walk-around that records every chip and stain before you touch the car. Our guide to car detailing pricing goes deeper, and the invoice template is for after.

How to register a car detailing business. In the US it's the same four steps in every state, with different fees. Form the business — an LLC is $40 in Kentucky (Kentucky SOS), $300 in Texas (Texas SOS) and $70 in California plus a $20 statement of information (California SOS), where every LLC also owes an $800 yearly tax (California FTB) — or file a DBA if you'll trade as a sole proprietor under a business name. Get the free EIN (IRS), open a business bank account, and get a city business license where your city wants one: Seattle's is $73 a year for a business with under $20,000 of revenue in the city and $147 from $20,000 to $499,999 in 2026 (City of Seattle). Our guide to whether you need an LLC walks through the choice.

Do you need a license to detail cars? For the detailing itself, no state license turned up — but cities permit mobile washers, the wash water is regulated in every city we checked, and some states tax the service. No state occupational license for car detailing appears on the Texas, California, Florida, New York or Washington pages we read; the paperwork is the registration above, plus:

• Mobile washer permits. El Monte, California, charges a mobile vendor permit of $158 plus $100 per vehicle and a $40 processing fee, requires a certificate of liability naming the city, and forbids using a residential property in connection with the business (City of El Monte). Lake Wales, Florida, registers mobile car washes with code compliance once they hold a business tax receipt, renewed yearly (City of Lake Wales). New York City requires a Car Wash License that "covers washing, detailing, drying, polishing and vacuuming" whether "at a fixed place or a mobile service" — $550 for up to two years and a $150,000 surety bond ($30,000 with a collective bargaining agreement) (NYC Business); "the penalty for operating an unlicensed mobile car wash is $100 per day" (NYC Department of Consumer and Worker Protection, May 2024).
• The wash water. The EPA frames it as a city stormwater matter and cites Fairfax County, Virginia's ordinance against "unpermitted commercial car wash water" in storm drains (EPA, February 2023). San Diego: "It is illegal to discharge polluted water from mobile business activities (pressure washing, pet grooming, mobile detailing, carpet cleaning, etc.) into the Municipal Separate Storm Sewer System" — "up to $10,000 per day per incident" — with disposal to landscaping or a sewer cleanout with the owner's permission (City of San Diego; City of San Diego, 2021). Austin: "Power washing and mobile car wash wastewater may not be discharged into the storm sewer if it contains pollutants or cleaning compounds," and an unauthorized discharge to the sanitary sewer is a Class C misdemeanor "punishable by a fine of up to $2,000 per day per violation" (Austin Water). Pinellas County, Florida: contaminated wash water and detergents "may not enter the street, stormdrain or gutter," with fines "up to $10,000 per day" (Pinellas County). A reclaim mat, a waterless or rinseless wash, or the customer's lawn: pick one before the first car.
• Working from home. San Diego allows one business vehicle on the street for a home occupation, "may not exceed a one-ton carrying capacity," and one customer on the premises at a time (City of San Diego, 2020); Orlando charges a $50 home occupation processing fee and bars outside storage of equipment (City of Orlando, 2022). Check your zoning before the van and the tank live in your driveway.
• Sales tax. New York taxes detailing performed by employees as a service (New York Department of Taxation, TB-ST-105); Washington lists "car wash … or detailing cars, trucks, campers, boats" among retail sales (Washington Department of Revenue); Florida exempts "a plain wash job" but taxes "the entire charge for a wash job, in which wax, silicones, or any other substance is added that forms a protective film or coating" (Florida Department of Revenue, Rule 12A-1.006); Texas's list of taxable services doesn't include car washing or detailing (Texas Comptroller, January 2026) and "sales tax is not due on the labor to maintain motor vehicles," though the "waxes, and polishes" you use up are taxable to you (Texas Comptroller, April 2026); California doesn't tax a pure service (CDTFA Regulation 1501; CDTFA). Check your state's revenue department and ask an accountant before you print a menu.
• Workers' compensation. California requires it from the first employee (California DIR); Texas leaves it optional for most private employers (Texas Department of Insurance). Federal safety law doesn't cover the self-employed — OSHA lists "self-employed workers" among those the OSH Act doesn't cover (OSHA) — but it covers you from your first helper.

Outside the US. In England and Wales, no registration for car valeting appears on gov.uk, but the water does: "Surface water drains discharge directly to the environment. You must make sure contaminated water from your premises and business activities goes into the foul drain or is recycled or removed," and to the foul drain only with your water company's consent (gov.uk, February 2026); a sole trader registers for Self Assessment once they earn more than £1,000 in a tax year (gov.uk). In Victoria, Australia, EPA tells the auto trade to wash in a wash bay or "use a mobile wash mat to collect wastewater," and that "you need a trade waste agreement with your water corporation before you can dispose of industrial waste into the sewerage system" (EPA Victoria, May 2025); Sydney Water requires "written permission before discharging trade wastewater," naming car washes (Sydney Water), and the ABN is free (business.gov.au). Wherever you are, confirm the rules with your council and an accountant before the first paid car.

Insurance. General liability pays when a polisher meets a mirror; garage keepers cover is the one detailers forget, and it's the one a dealership asks about. Insureon's averages for auto detailing and car wash businesses are $54 a month ($646 a year) for general liability, $89 a month for a business owner's policy, $46 a month ($550 a year) for commercial auto and $131 a month ($1,567 a year) for workers' compensation (Insureon, March 2025). Garage keepers insurance "protects against accidental damage to a vehicle in your care, custody, or control" — "no matter who is at fault," including vandalism and weather, but not the customer's belongings inside the car and not "faulty repair work" — and auto service professionals pay $38 a month on average (Insureon, December 2023; Insureon). "Almost every state requires" commercial auto for company-owned vehicles, and "most states require workers' comp for car washes and detailers that have employees" (Insureon). Get quotes from more than one insurer.

Franchise or independent? Three franchisors print their figures. DetailXPerts' initial fee is $35,000 and its total investment $103,500 to $240,100 (DetailXPerts); Ziebart's fee is $45,000, its total $450,100 to $924,000, with a $750,000 net worth requirement and royalties of 8% falling to 5% (Ziebart); Tint World's total is $239,950 to $449,950, and its top half of stores averaged $1,060,773 in revenue in its 2026 disclosure document (Tint World) — the franchisors' own words, from their own pages. Every owner quoted in the next section went independent, and one started with $500.

The business, and the calendar. Offer a maintenance plan at the end of every detail, pitch a used-car lot or a small fleet on a fixed wash day, and keep the coating work for the days the skill is ready. For one owner starting mobile, our free car detailing business plan puts the start at $2,399–$14,920: the kit, chemicals, a water tank — a generator at the high end — a year of general liability with garage keepers and commercial auto at the high end, registration, a city license or mobile permit, the website, software, and two months of running costs. Your own vehicle and living costs come on top.
