  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 Iowa

3 stops

  1. Iowa Business Registration

    A mobile car wash or auto detailing business organized as an LLC, corporation, or limited partnership registers with the Iowa Secretary of State, online through Fast Track Filing. A sole proprietor operating under a name other than their own legal name instead records a verified trade name statement with the county recorder where the business is located, under Iowa Code chapter 547; Iowa has no state-level DBA filing. An LLC is worth considering here because mobile work is done on customers' property.

    Official government source

    $50 to file an LLC certificate of organization or for-profit articles of incorporation with the Secretary of State; $7 for a one-page county trade name filing; nothing if a sole proprietor uses their own legal name. LLCs also file a $30 biennial report onlineOnline filings through Fast Track Filing are usually processed within a few business days

  2. Iowa Stormwater and Wastewater Compliance

    Mobile car wash wastewater carries detergents, surfactants, oils, and road grime. Iowa rules, consistent with the federal Clean Water Act, prohibit discharging it to storm drains, street gutters, or waterways. Capture the wash water with a containment mat and a wet vacuum or pump, or make sure it drains to a sanitary sewer inlet. Iowa's environmental regulator is the Iowa Department of Natural Resources (Iowa DNR) - there is no "Iowa Department of Environmental Quality." Operators using hazardous solvents or degreasers should check with DNR about permitting.

    Official government source

    No routine registration or permit fee for ordinary containment-and-recovery operation; costs are the containment mat and recovery equipment you buyNo application to wait on when you contain and recover wash water; allow several weeks if DNR determines a discharge permit is needed

  3. Iowa Sales Tax Permit

    Car washing and auto detailing are enumerated taxable services in Iowa, so a mobile car wash does need to collect sales tax. Register with the Iowa Department of Revenue through GovConnectIowa to get a sales and use tax permit, then charge the 6% state rate plus any local option sales tax that applies where the service is performed. Keep records of every transaction and file on the schedule the department assigns you.

City of Des Moines / Polk County

4 stops

  1. No General Business License Required in Des Moines

    Des Moines does not issue a general business license, so a mobile car wash or detailing business needs none. The City Clerk licenses only specific activities — alcohol, tobacco, transient merchant, mobile food vendor, peddler, pawn shop, theater, solid waste hauler, salvage dealer and similar — and mobile detailing is not among them. What does apply is zoning for where you store equipment, permission from property owners where you work, and the city's stormwater rules on wash water.

    Official government source

    $0 — no such license existsNot applicable

  2. Des Moines Stormwater Discharge Compliance (mobile car wash)

    Des Moines prohibits discharging anything but clean stormwater into storm drains, gutters, or waterways under its illicit discharge ordinance, enforced by Public Works' Clean Water Program. Mobile car wash and detailing wastewater carries detergents, oils, and road grime, so capture it — a containment mat or berm plus a vacuum extractor is the usual method — and dispose of it to the sanitary sewer or another approved route rather than the street. The city issues no permit or registration for this; the rule applies directly.

    Official government source

    $0 — there is no permit fee; violations carry enforcement penaltiesNo application; comply from your first job and call the Clean Water Program (515-283-4950) with disposal questions

  3. Chemical Handling for Mobile Detailing (no Polk County registration exists)

    There is no Polk County chemical use registration for mobile detailers - the requirement as written does not exist. What does apply: if you use degreasers, solvents, or other hazardous cleaning products, keep a Safety Data Sheet for each one and follow the labelled storage and disposal instructions, per OSHA hazard communication rules and the local fire code. Wash water and spent solvent must not go to a storm drain. Polk County Public Health handles environmental health questions if you are working near a sensitive waterway.

    Official government source

    No registration and no feeNothing to apply for

  4. Des Moines Home Occupation Review (if operating from a residence)

    A mobile car wash operator who parks the vehicle and keeps equipment and supplies at a Des Moines residence goes through home occupation review with the Zoning Enforcement Division in Neighborhood Services, which handles home occupation applications and reviews. Typical conditions are no employees or clients meeting at the house, no exterior signage, and no chemical storage at a scale that would trigger fire code or hazmat requirements. Reach the division at [email protected] or 515-283-4207.

    Official government source

    No home occupation fee is published by the Zoning Enforcement DivisionAllow a couple of weeks for zoning staff to review and respond
