North Potomac is a county-run, unincorporated area wedged between Gaithersburg to the north, Rockville to the east, Travilah to the south and Darnestown to the west. Farmland that grew tobacco, then wheat and dairy, now holds subdivisions, a Universities at Shady Grove campus and Muddy Branch Stream Valley Park, a greenway of more than 876 acres. The DuFief Mill site and Maple Spring Barns recall the farming past.
Our restroom trailers, mobile shower trailers and shower and restroom combination trailers are ADA-accessible, delivered to your site and available as short-term rentals or long-term leases.
North Potomac is unincorporated, so Montgomery County handles permits; the Department of Permitting Services runs the special event process for events open to the public. Where food is served, the county's Licensure and Regulatory Services office issues Special Food Event licenses, and its page asks for a well and septic permit where applicable and says to allow 30 days for well water testing and septic inspection. Events in Muddy Branch Stream Valley Park need a Montgomery Parks permit.
Start the health review early if the site uses a well or septic system, since the county advises allowing 30 days for testing and inspection.

County health: Department of Health and Human Services (DHHS), Licensure and Regulatory Services: licenses Special Food Events (fixed location, up to 30 consecutive days; application at least two working days ahead). No county rule specific to restroom or shower trailers was found, so ask DHHS and DPS whether a trailer with a wastewater connection or holding tank needs review.

Parts of North Potomac are farm-descended lots, and the county's Special Food Event page treats well and septic as a real scheduling factor: it asks for a well and septic permit where applicable and says to allow 30 days for well water testing and septic inspection. Anyone planning a party or fundraiser with food service on such a lot should start that process early, because restroom and handwashing arrangements are often reviewed alongside it. The county's general sanitation requirements document can be requested from Licensure and Regulatory Services.
