  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 Alabama

3 stops
  1. Alabama Business Registration

    Mobile car wash and auto detailing businesses operating in Alabama as an LLC, corporation, or partnership must register with the Alabama Secretary of State. Sole proprietors are not required to file a DBA; a trade name filing with the Secretary of State is optional. An LLC is recommended to protect personal assets, as mobile operations working at customers' properties carry inherent liability.

  2. Alabama Environmental / Stormwater Compliance

    Mobile car wash operations generate wastewater containing detergents, surfactants, oils, and road grime. Alabama environmental regulations — consistent with federal Clean Water Act requirements — prohibit discharge of this wash water to storm drains, street gutters, or waterways; no person may discharge pollutants into waters of the state without a valid NPDES permit or coverage under a general NPDES permit. Operators should use a wastewater containment mat and recovery system (wet/dry vacuum or pump), or ensure wash water flows to a sanitary sewer inlet. Contact the Alabama Department of Environmental Management (ADEM) Water Division for compliance guidance.

    Official government source

    No fee for the compliance obligation itself; NPDES permit fees apply only if a permit is required — confirm with ADEMOngoing compliance obligation; permitting timelines apply only if a permit is required

  3. Alabama Sales Tax Registration (Alabama Department of Revenue)

    Alabama sales tax is a privilege tax on the retail sale of tangible personal property; services such as car washing and detailing are generally not taxed, though labor to fabricate an item is taxable and any retail products you sell are. Register with the Alabama Department of Revenue through My Alabama Taxes if you will make taxable retail sales, and confirm your specific obligations with ADOR.

City of Montgomery / Montgomery County

4 stops
  1. City of Montgomery Business License

    Mobile car wash and auto detailing businesses operating in Montgomery must obtain a city business license from the Finance Department's License and Revenue Division. The application asks for your business entity information, contact details and a description of services, and the license is renewed annually. Confirm with the division whether one license covers mobile work across the city and whether any additional location or home-occupation approval applies.

  2. Stormwater / Wastewater Discharge Compliance (Montgomery)

    Mobile car wash wastewater must not be discharged to storm drains, gutters or waterways: wash water carries detergents, oils and road grime. Under Alabama's NPDES program, administered by the Alabama Department of Environmental Management, no person may discharge pollutants to waters of the state without an NPDES permit or coverage under a general permit. Operators should contain runoff (berm or mat), recover it with a wet/dry vacuum or pump, and dispose of it to sanitary sewer with permission or through a licensed disposal facility. Confirm local requirements with the City of Montgomery, whose site blocks automated access.

    No fee is published for the compliance obligation itself; NPDES permit fees apply only if a permit is required - confirm with ADEMOngoing compliance obligation; no registration window is published

  3. Hazardous Materials and Wastewater Compliance (no chemical-use registration confirmed)

    No 'chemical use registration' program for mobile detailers could be confirmed at Montgomery County or the City of Montgomery. Operators using cleaning agents, engine degreasers or solvents must still keep a Safety Data Sheet for each chemical under OSHA rules, store and dispose of them properly, and comply with ADEM's NPDES/stormwater rules barring pollutant discharge to waters of the state.

    Official government source

    No registration fee - no such county registration was confirmed to existNot applicable - no confirmed registration process

  4. Montgomery Home Occupation / Residential Zoning Approval (if operating from residence)

    Mobile car wash operators storing equipment at a residential address in Montgomery should confirm home occupation permit or residential zoning requirements with the City of Montgomery before operating. The city's website blocks automated access, so the administering office, restrictions and fee could not be confirmed from an official source - contact the city directly.
