Call (888) 385-5513Planning an event restroom trailer rental for the Tri-County Fairgrounds in Petersburg? The drive to the fairgrounds and other Grant County sites is about 4 hours 15 minutes from Maryland. Late-evening and early-morning calls are welcome, emergency delivery requests can be made at any time, and ADA-compliant stalls that include a ramp can be had on short-term rental, long-term rental or leasing terms.

Petersburg is the Grant County seat, set where the North Fork joins the South Branch of the Potomac. Its calendar leans on the Tri-County Fair, which Grant, Hardy and Pendleton counties share, and on the Spring Mountain Festival in late April. Grant Memorial Hospital and the county schools keep weekday traffic steady, and the Petersburg Wave draws glider pilots each March. Temporary restrooms and showers tend to be needed for crowds, work crews and long event days at these sites.
Decide early whether the site is city property, a county park or the fairgrounds, since each has a different office to ask, and keep the trailer clear of riverbank ground when the South Branch is running high.

Petersburg grew where the North Fork meets the South Branch of the Potomac, and the river has a long flood record, with major floods in 1924, 1936 and 1949 and the great flood of 1985. Riverside sites such as Welton Memorial Park, which has a walking trail and two boat ramps on the South Branch, are pleasant for events but sit close to the water. Before choosing a spot, ask City Hall whether the location falls inside the mapped flood area, watch the forecast in the days before delivery, and pick firm, level ground with room for a service vehicle to turn around.
Two recurring events set the busiest stretches of the Petersburg calendar. The Tri-County Fair usually runs from late July into the first days of August at the fairgrounds, with evening concerts, a demolition derby and 4-H and FFA programs drawing families from Grant, Hardy and Pendleton counties. The Spring Mountain Festival, organized by the Grant County Chamber of Commerce, usually takes place the last weekend of April and has included a parade, a car, truck and tractor show and a motorcycle show. Both reward early planning, because restroom and shower needs are fixed by the event dates.

The free Spring Mountain Festival brings parade-day and car-show crowds in late April, and Town Park pavilions host gatherings through the warm months. ADA restroom stalls help where the permanent facilities are limited.
The South Branch has flooded the town in 1924, 1936, 1949 and 1985. After high water, repair and cleanup crews may need a shower and restroom trailer on site for the duration of the work.
Inside Petersburg city limits, City Hall is the first office to contact about placing a trailer on city streets, lots or other city property. Town Park lies in the city but is run as a Grant County park, so pavilion reservations there go through county Parks and Recreation. The Tri-County Fairgrounds is operated by the Tri-County Fair Association. No published special-event or temporary-trailer permit form for Petersburg could be found, so the city office should confirm what applies.
Permit office: City of Petersburg City Hall
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.
Town Park sits in Petersburg but is operated as one of the Grant County parks, and the county lists its pavilions among reservable shelters. Start with Grant County Parks and Recreation, then check with City Hall if the trailer would touch city streets or other city property.
The fair is typically held in the last week of July into the first days of August at the Tri-County Fairgrounds in Petersburg; the 2026 fair ran July 25 to August 1. It is organized by the Tri-County Fair Association for Grant, Hardy and Pendleton counties, so fairground space is arranged with the association.
The South Branch of the Potomac flooded Petersburg badly in 1924, 1936, 1949 and 1985, and FEMA publishes a flood map for the city. Riverside spots such as parks along the bank deserve a check with City Hall, and a delivery site on higher, firm ground is the safer choice.
Petersburg is in Grant County, West Virginia. Closest Maryland service cities:
Moorefield is roughly 9 miles northeast of Petersburg, in Hardy County rather than Grant County. Delivery crosses the boundary to reach it. Nine miles and a different county are both ordinary for Petersburg, so Moorefield is easy to include in the coverage here.
