City of Dallas / Dallas County

3 stops

  1. City of Dallas -- No General Business License Required

    The City of Dallas does not require a general business license, occupational license, or citywide business registration -- no such license exists. The city's operating approval for a business occupying a commercial space is the Certificate of Occupancy, applied for through the DallasNow portal (Dallas Development Services). Home-based and mobile businesses with no commercial premises generally need no city-level general license, only compliance with zoning and any industry-specific permits.

  2. Stormwater / Wastewater Discharge Compliance

    Pressure washing businesses in Dallas must comply with the city's stormwater ordinance: wastewater containing detergents, oils, or other pollutants may not enter storm drains and generally must be captured and disposed of to the sanitary sewer. This is a compliance requirement, not a permit. Confirm specifics with City of Dallas stormwater staff (Dallas Water Utilities); TCEQ administers the statewide stormwater program.
