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. New Jersey Business Registration

   Mobile car wash and auto detailing businesses formed as a corporation, LLC, LP or LLP must file a Certificate of Formation/Authorization with the New Jersey Division of Revenue and Enterprise Services, then file the tax/employer registration form NJ-REG. Sole proprietors and general partnerships file only NJ-REG; a sole proprietor using a trade name registers that name with the county clerk, not the State. An LLC is commonly chosen for liability protection because mobile detailing work happens on customers' property.

2. New Jersey Environmental / Stormwater Compliance

   Mobile car wash operations generate wastewater containing detergents, surfactants, oils, and road grime. New Jersey 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 New Jersey Department of Environmental Protection (NJDEP) for compliance guidance.

3. New Jersey Sales Tax Registration

   Car washing and auto detailing are taxable in New Jersey: the Sales and Use Tax Act taxes charges for maintaining, servicing or repairing tangible personal property, including motor vehicles (Publication ANJ-6, Auto Repair Shops). Register by filing the Business Registration Application (Form NJ-REG) with the Division of Revenue and Enterprise Services; indicate that you will collect sales tax and the Division issues a New Jersey Certificate of Authority (Form CA-1). New Jersey has a single statewide 6.625% rate and no additional local sales tax, so there is no local rate to add. Keep records of all transactions and file returns on the schedule the Division of Taxation assigns.

1. Newark Business Licensing — No General Business License

   Newark does not issue a general business license covering all businesses. The City's Online Business Portal licenses only specific enumerated trades — restaurants, retail, bakeries, dry cleaners, building contractors, public garages, tire shops, used car lots and similar — and mobile car wash or auto detailing is not a listed category. Check with the City's online license hotline (973-877-9415) whether any listed category applies. A home-based operation is separately subject to Newark's home-occupation zoning rules (Zoning and Land Use Regulations Sec. 41:4-6-8), administered by the Division of Planning and Zoning.

2. Stormwater Discharge Prohibition (mobile car wash wastewater)

   Car-wash wastewater is not clean stormwater. New Jersey's stormwater rules and the municipal separate storm sewer (MS4) permitting program administered by NJDEP prohibit discharging it to storm drains, gutters or waterways, and Newark enforces the same prohibition through its own stormwater and sewer rules. Operate with a portable containment berm or mat to capture runoff, recover the wash water with a wet/dry vacuum or pump, and dispose of it to a sanitary sewer connection with the sewer authority's permission or through a licensed disposal facility. This is an operating prohibition, not a permit — non-compliance is enforced by fine.

3. Hazardous Chemical Handling and Wash-Water Disposal Compliance

   Essex County does not run an 'Environmental Health' department or a chemical-use registration program — its health functions are the Division of Community Health Services and the Office of Public Health Management, neither of which registers cleaning chemicals. What does apply to a mobile detailing business using degreasers, solvents or strong cleaners: keep a Safety Data Sheet on hand for every chemical under the federal OSHA Hazard Communication Standard, store and dispose of each product according to its label and NJDEP rules, and keep wash water and solvent residue out of storm drains, which New Jersey's municipal stormwater rules prohibit. Capture and dispose of your wash water properly rather than letting it run to the curb.

4. Newark Home Occupation Zoning Permit (if operating from residence)

   Newark regulates home-based businesses as 'home occupations' under its Zoning and Land Use Regulations (Sec. 41:4-6-8), administered by the Division of Planning & Zoning. Key limits relevant to a mobile car wash: any vehicle associated with the home occupation must have a designated on-site parking space in a driveway or garage; no outdoor storage of goods or materials is permitted; there must be no change in the dwelling's appearance or other visible evidence of the business (no signage or artificial light); at most one non-resident employee; the business may use no more than 20% of the dwelling's gross floor area; and it may not produce noise, odor, fumes, waste run-off or other nuisance outside the dwelling. Newark's zoning definition of home occupation excludes automobile or other vehicle repair, so repair work may not be conducted at the residence.
