City of Silver Spring / Montgomery County

3 stops

  1. No Local General Business License Required

    Silver Spring is an unincorporated community in Montgomery County with no city government, so there is no Silver Spring business license. Neither Maryland nor Montgomery County requires a general business license; the Clerk of the Circuit Court licenses only specific activities (e.g., retail Trader's License), which do not cover pressure-washing services. No local general business license is required to operate.

  2. Stormwater / Wastewater Discharge Compliance

    Pressure washing businesses in Silver Spring must comply with Montgomery County stormwater rules. Wastewater containing detergents, oils, or other pollutants cannot be allowed to enter storm drains; wash water must be contained and directed to the sanitary sewer or collected for proper disposal. Contact the Montgomery County Department of Environmental Protection for specific requirements; the Maryland Department of the Environment regulates discharges at the state level.
