Evansville / Vanderburgh County Requirements
4 requirementsEvansville General Business License
All mobile car wash and auto detailing businesses operating in Evansville must obtain a general business license from the city. Mobile operations that travel to customers throughout the city are covered by a single city license. The application requires your business entity information, contact details, and a description of services. Renewed annually.
Evansville Stormwater / Wastewater Discharge Compliance
Evansville prohibits the discharge of mobile car wash wastewater into storm drains, gutters, or waterways. Wash water contains detergents, oils, and road grime that are harmful to local waterways. Operators must: (1) use a portable containment berm or mat to capture runoff, (2) vacuum up wash water with a wet/dry vac or pump, and (3) dispose of collected water at an approved sanitary sewer access point or licensed disposal facility. The city's Public Works or Stormwater division may conduct inspections. Violations may result in fines.
Vanderburgh County Environmental Health — Chemical Use Registration (if applicable)
Mobile detailing operations in Vanderburgh County that use chemical cleaning agents, engine degreasers, or solvents beyond standard car wash soap may need to register with the county Environmental Health department. Businesses using hazardous materials must maintain a Safety Data Sheet (SDS) for each chemical and comply with proper storage and disposal requirements.
Evansville Home Occupation Permit (if operating from residence)
Mobile car wash operators who store their vehicle, equipment, and supplies at a residential address in Evansville may need a Home Occupation Permit from the city. Restrictions typically include: no employee meetings at the residence, no exterior signage, and no large-scale storage of chemicals that would require hazmat permits.
Indiana State Requirements
3 requirementsIndiana Business Registration
Mobile car wash and auto detailing businesses operating in Indiana must register with the Indiana Secretary of State 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.
Indiana Environmental / Stormwater Compliance
Mobile car wash operations generate wastewater containing detergents, surfactants, oils, and road grime. Indiana environmental regulations — consistent with federal Clean Water Act requirements — prohibit discharge of this wash water to storm drains, street gutters, or waterways. Operators must use a wastewater containment mat and recovery system (wet/dry vacuum or pump), or must ensure wash water flows to a sanitary sewer inlet. Operators using hazardous cleaning solvents or degreasers may require a state permit. Contact the Indiana Department of Environmental Quality for compliance guidance.
Indiana Sales Tax Registration
Car washing and auto detailing services are typically subject to sales tax in Indiana. Register with the Indiana Department of Revenue to obtain a seller's permit and collect the appropriate state and local sales tax from customers. Keep records of all transactions and remit taxes on the required schedule.

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.
