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.

1. Louisiana Secretary of State Business Registration

   A mobile car wash or auto detailing business organized as an LLC, corporation or partnership files its formation documents with the Louisiana Secretary of State's Commercial Division through the geauxBIZ portal. A sole proprietor operating under any name other than the owner's own legal name registers a trade name with the Secretary of State — Louisiana has no parish-clerk DBA filing. An LLC is commonly chosen for liability separation because mobile crews work on customers' property, though the entity does not substitute for liability insurance.

2. Louisiana Stormwater and Wastewater Discharge Compliance (no permit or registration)

   Mobile car wash wastewater carries detergents, surfactants, oils and road grime. Under the Clean Water Act and the Louisiana Water Quality Regulations administered by the Louisiana Department of Environmental Quality's Water Permits Division, that wash water may not be discharged to storm drains, street gutters, ditches or waterways. Contain runoff with a berm or containment mat, recover it with a wet/dry vacuum or pump, and dispose of it to a sanitary sewer inlet with the sewer authority's permission or at a licensed facility. There is no LDEQ registration or permit created specifically for mobile car washing; an LPDES permit is required only if your operation has a discharge that needs one. Solvents and degreasers additionally trigger hazardous-waste storage, labeling and disposal duties.

   Official government source

   No registration or permit fee applies to an ordinary mobile car wash — this is a compliance obligation, not a paid application. Budget instead for containment and recovery equipment and for disposal. LDEQ charges fees only where an LPDES permit or coverage is actually required.·Not applicable — there is nothing to apply for and no waiting period. The prohibition applies continuously from the day you operate. Contact the LDEQ Water Permits Division before you start if you are unsure whether your operation needs LPDES coverage.

3. Louisiana Sales Tax Registration

   Louisiana taxes only specifically enumerated services, and car washing/auto detailing is not among them. Register as a dealer with the Louisiana Department of Revenue only if you also sell, lease or rent tangible personal property or digital products — for example retail car-care products (R.S. 47:301(4)). Local sales tax may still apply to goods you sell; confirm with LDR and your local collector.

1. New Orleans General Business License

   Mobile car wash and auto detailing businesses in New Orleans must obtain an Occupational License from the Bureau of Revenue (Department of Finance) — there is no City Clerk business-licensing office. Apply through the One Stop App; an active Louisiana Secretary of State filing is required. A single city license covers mobile operations travelling to customers across the city. Licenses expire December 31 and are renewed annually (Form 8030 or online).

   Official government source

2. Stormwater / Wastewater Discharge Compliance (no city permit)

   Mobile car wash wastewater carrying detergents, oils and road grime may not be discharged into storm drains, gutters or waterways in New Orleans. Contain runoff with a portable berm or mat, recover it with a wet/dry vacuum or pump, and dispose of it at an approved sanitary sewer access point or licensed facility. This is a continuing compliance obligation under city ordinance and state water-quality law — no standalone city permit, registration or inspection program for mobile car washes was identified. Drainage and sewer questions go to the Sewerage & Water Board or the Department of Public Works; state water-quality permitting is LDEQ's.

3. Chemical Handling and Wastewater Compliance (no Orleans Parish registration exists)

   There is no Orleans Parish 'Environmental Health chemical use registration' — the City of New Orleans and Orleans Parish are consolidated and no such program exists. Mobile detailing operations using cleaning agents, degreasers or solvents must maintain a Safety Data Sheet for each chemical and follow OSHA storage, labeling and disposal rules, and must not discharge wash water or solvents to storm drains; state water-quality permitting is administered by the Louisiana Department of Environmental Quality's Water Permits Division.

4. Certificate of Occupancy (Home Business)

   New Orleans has no separate 'Home Occupation Permit.' A mobile car wash operator who stores the vehicle, equipment and supplies at a residential address needs a Certificate of Occupancy (Home Business) from the Department of Safety and Permits; each business location must be inspected and approved. Apply through the One Stop App with an Acknowledgment of Limitations on Home Occupations and, for renters, a letter of permission from the property owner. Limits include no exterior signage and no on-site customer traffic; bulk chemical storage may trigger separate requirements.
