ADA-Accessible Trailers. Delivered Across Maryland, 24/7.
Call (888) 385-5513Fair week at the Montgomery County Agricultural Fairgrounds suits an eight-stall 30 ft trailer, while contractors at federal campuses like NIST can use a combination trailer with both showers and restrooms, which generally require advance clearance. For Gaithersburg, ADA-compliant ramp access is available. The route is about 1 hour by our drive-time estimate, and the phone is open all hours for emergency delivery, for short or long terms.

Gaithersburg is a Montgomery County city in central Maryland along I-270, north of Rockville. It is home to the Montgomery County Agricultural Fairgrounds, the National Institute of Standards and Technology campus, and planned communities such as Kentlands and Crown. Temporary restrooms and showers are used at fair and fairground events, city park festivals, and construction or contractor crews working on technology, lab and residential projects.
Common needs in Gaithersburg: pharma and biotech, county fairgrounds, NIST.
Call it a bathroom trailer or a portable restroom trailer: it arrives on wheels, connects to water and power, and leaves when the work or event ends. Rent for days, or lease for months.
Anyone planning an event in Gaithersburg should start with the certificate of insurance, because the City's special event permit voids if the City is not named as co-insured. Applications are due at least two weeks before the event, and the City's event toolkit calls for a City tent permit above roughly 10 by 10 feet (other City material says 12 by 12), so check the current size with the City. Maryland law also requires recycling collection at special events. Questions go to the City's permitting staff or Parks, Recreation and Culture.
County office: Department of Permitting Services (DPS), 7th floor, Wheaton, MD 20902; (MC311); https://www.montgomerycountymd.gov/department-permitting-services
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.
Permit rules and event dates change, so confirm current requirements with the office before you order. Water and power hookups are confirmed in your quote. For federal and state basics (OSHA, ADA, wastewater) read the Maryland rules guide.
