  2. EPA Stormwater Compliance — Clean Water Act Section 402

    Mobile car wash operations that discharge wash water are subject to the federal Clean Water Act. The EPA's National Pollutant Discharge Elimination System (NPDES) prohibits discharge of polluted wash water to storm drains or waterways without a permit. Most mobile operators achieve compliance by using containment systems and disposing of water via sanitary sewer. Larger operations (e.g., fleet washing facilities) may require an NPDES permit.

State of Kentucky

  1. Kentucky Business Registration

    Mobile car wash and auto detailing businesses organized as an LLC, corporation, or limited partnership must file organizing documents with the Kentucky Secretary of State and file an annual report each year. A business operating under a trade name other than its real name must also file a certificate of assumed name under KRS 365.015: a sole proprietor files it with the county clerk of the county where the principal place of business is located, while an LLC, corporation, or limited partnership files it with the Secretary of State and then records a file-stamped copy with the county clerk. An LLC is commonly chosen to limit personal liability for work performed on customers' property.

    Official government source

    $40 to file LLC articles of organization or for-profit articles of incorporation (corporations also owe organization tax, $10 minimum); $15 annual report; certificate of assumed name $20 at the Secretary of State, or the county clerk's KRS 64.012 recording fee ($33 for five pages or fewer; the Jefferson County Clerk publishes $46) for a sole proprietorSecretary of State filings are effective on the date filed; the assumed-name certificate runs five years and is renewable

  2. Kentucky Environmental / Stormwater Compliance

    Mobile car wash operations generate wastewater containing detergents, surfactants, oils, and road grime. Kentucky water quality regulations in 401 KAR Chapters 5 and 9, administered by the Division of Water in the Energy and Environment Cabinet and consistent with the federal Clean Water Act, prohibit discharging this wash water to storm drains, street gutters, or waterways. Operators must use a containment mat with a recovery system (wet/dry vacuum or pump) or route wash water to a sanitary sewer with the local sewer utility's approval. There is no Kentucky Department of Environmental Quality; contact the Division of Water for guidance.

    Official government source

    No fee — this is a self-compliance obligation, not a permit; a KPDES permit is required only for a direct discharge to waters of the CommonwealthImmediate — no application or approval step for ordinary containment-and-recovery compliance

  3. Kentucky Sales and Use Tax Registration

    Kentucky's 6% sales tax applies to retail sales of tangible personal property and to the specific services enumerated in KRS 139.200. Car washing and auto detailing are not among the enumerated taxable services in that statute, so the labor itself is generally not taxable; however, any tangible products a detailer sells to the customer (waxes, air fresheners, accessories) are taxable retail sales, and the business owes use tax on supplies bought without tax. Register for a sales and use tax account through the Kentucky Department of Revenue's One Stop Business Portal, and confirm your specific services with the Department before deciding not to collect.

    Official government source

    No fee to register for a Kentucky sales and use tax account; the tax rate is 6% of gross receipts on taxable salesNot published by the Department of Revenue; One Stop registration is completed online

City of Lexington / Fayette County

4 stops
  1. Lexington-Fayette Urban County Government — Occupational License

    Any business entity operating in Fayette County, including a mobile car wash or auto detailing business travelling to customers, must apply for and obtain an initial occupational license from the LFUCG Revenue Department before starting. LFUCG does not issue a flat-fee general business license: the occupational license fee is 2.25% of an individual's compensation and a business's net profits, reported on an annual Net Profits License Fee Return. Employers also file an Employer's Return of License Fee Withheld quarterly, or monthly when quarterly withholding exceeds $300, plus an annual reconciliation.

    Official government source

    $100 initial license fee and a $100 annual minimum license fee, plus the 2.25% occupational license fee on net profits and payrollNot published by the LFUCG Revenue Department; the license must be obtained before starting business

  2. Lexington Stormwater / Wastewater Discharge Compliance

    LFUCG runs an MS4 stormwater program under a permit issued every five years by the Kentucky Division of Water, administered locally by the Water Quality Division of Environmental Quality and Public Works. The program bars pollutant discharges to the storm sewer system, which covers mobile car wash water carrying detergents, oils, and road grime. Operators should contain runoff with a portable berm or mat, recover it with a wet/dry vacuum or pump, and dispose of it to a sanitary sewer connection or a licensed disposal facility rather than a storm drain, gutter, or waterway.

    Official government source

    No fee — this is a discharge prohibition, not a permit or registration for individual operatorsImmediate — compliance applies from the first day of operation; there is no application step

  3. Hazardous Chemical Handling (OSHA Hazard Communication)

    Fayette County has no chemical-use registration for mobile detailing. The Lexington-Fayette County Health Department's environmental health programs are food protection, food handler certification, mosquito control, onsite sewage, public swimming pools, rabies control, radon, and tattoo parlors — none of which registers cleaning chemicals. A detailer using cleaning agents, engine degreasers, or solvents must instead keep a Safety Data Sheet for each chemical and follow labeling, storage, and disposal rules under the federal OSHA Hazard Communication Standard (29 CFR 1910.1200), enforced in Kentucky by the Kentucky Occupational Safety and Health Program. Wash water disposal is separately governed by LFUCG's stormwater ordinance.

    Official government source

    No fee — no registration exists; OSHA Hazard Communication compliance carries no filing costNot applicable — there is nothing to apply for

  4. Lexington Home Occupation Zoning Compliance (if operating from a residence)

    A mobile car wash operator storing a vehicle, equipment, and supplies at a Lexington residence is governed by the home occupation provisions of the LFUCG Zoning Ordinance, administered by the Division of Planning within Planning and Preservation at 101 E. Vine St. Home occupations are treated as an accessory use subject to conditions such as no customer or employee traffic, no exterior signage, and no outdoor or bulk storage; LFUCG publishes no standalone Home Occupation Permit or fee. Zoning questions and permit applications run through the Accela citizen portal and the One Stop Lexington zoning portal.

    Official government source

    No separate home occupation permit fee is published by LFUCG; zoning and construction fee estimates are available through the One Stop portalNot published by LFUCG Planning and Preservation
