  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 Florida

3 stops
  1. Florida Business Registration

    Mobile car wash and auto detailing businesses operating in Florida must register with the Florida Division of Corporations (Sunbiz) if structured as an LLC, corporation, or partnership. Sole proprietors using a trade name must file a DBA registration. An LLC is recommended to protect personal assets, as mobile operations working at customers' properties carry inherent liability.

  2. Florida Environmental / Stormwater Compliance

    Mobile car wash operations generate wastewater containing detergents, surfactants, oils, and road grime. Florida rules - consistent with federal Clean Water Act NPDES requirements - prohibit discharging wash water to storm drains, street gutters, or waterways. Operators should use a containment mat and recovery system (wet/dry vacuum or pump) or direct wash water to a sanitary sewer. Operators using hazardous cleaning solvents may need additional handling compliance. Contact the Florida Department of Environmental Protection (DEP) for compliance guidance.

    Official government source

    Free–$200 (registration or permit fee, if required)1–4 weeks (if permit required; otherwise immediate with self-compliance)

  3. Florida Sales Tax Registration

    Auto detailing that applies materials (wax, sealants, protectants) is taxable in Florida as maintenance of tangible personal property that includes materials (Rule 12A-1.006, F.A.C.); washing-only services where no tangible personal property is transferred are exempt. Register with the Florida Department of Revenue, collect the applicable state (6%) plus county surtax on taxable charges, keep transaction records, and remit on schedule.

City of Miami / Miami-Dade County

4 stops
  1. Miami General Business License

    Mobile car wash and detailing businesses operating in the City of Miami must obtain a Business Tax Receipt, renewed annually — mobile businesses without a fixed commercial location in the city can apply directly for the BTR (no Certificate of Use needed). A Miami-Dade County Local Business Tax Receipt is also required.

    Official government source

    Varies by business classification under the City of Miami fee schedule; no citywide fee range is published on the official BTR page — confirm with the City of Miami at (305) 416-20871–2 weeks

  2. Miami Stormwater / Wastewater Discharge Compliance

    Mobile car wash operators in Miami may not discharge wash water into storm drains, gutters or waterways. Contain runoff (berms/mats), recover water with a wet/dry vacuum, and dispose to a sanitary sewer or approved facility. Miami-Dade DERM enforces countywide water-quality rules (county code Chapter 24), and the city can cite illegal discharges.

    Official government source

    No permit fee for basic compliance; fines possible for illegal discharge1–3 weeks (self-certify compliance before operating)

  3. Miami-Dade County Environmental Health — Chemical Use Registration (if applicable)

    No Miami-Dade County chemical-use registration for mobile detailing businesses could be verified. Businesses storing or disposing of significant quantities of solvents or degreasers are subject to Miami-Dade DERM hazardous-materials and waste rules (county code Chapter 24) and should keep Safety Data Sheets and use proper disposal; contact DERM if you store regulated quantities.

    No verified county registration or fee exists for ordinary detailing chemicals1–2 weeks

  4. City of Miami Accessory Use (home-based business)

    A mobile car wash operator based at a Miami residence applies for an Accessory Use (the home-based counterpart of the Certificate of Use) through MiamiBiz, then the Business Tax Receipt. Florida's home-based business law (§559.955) limits what the city may restrict: the business may not be regulated more strictly than similar residences, with allowances for regulating visible heavy equipment and on-street vehicle parking.
