What does Arlington require for a special event?
Arlington's Office of the Fire Marshal runs special event fire-code permits for events affected by the Virginia Statewide Fire Prevention Code or the Arlington County Fire Prevention Code. The county's page does not mention portable toilets.
The fire-code permit is about the event's fire safety, and the plan for it may include the layout of the site. A unit placed where it would block a fire route or a hydrant is a matter for the fire code, and the spot is shown on the plan. The county's page does not set a portable toilet rule, so the organiser confirms the restroom arrangements with the county.
Arlington's Rosslyn and Ballston corridor is a dense construction area, and a unit on a construction lot follows the county's own construction and public space rules, which the provider checks for the spot.
What is the rule in Alexandria?
No portable toilet rule was found for the City of Alexandria. The city is an independent city with its own permits, and the spot is checked with the city before the booking.
Alexandria's Old Town and its waterfront draw large events, and its streets are narrow and historic. A unit on a public street or the waterfront needs the city's permit route for that space, and the plan states the route. Because no sourced rule was found for portable toilets, the organiser is asked to confirm the requirement with the city before the unit is booked.
Where a city permit is needed for a street closure or a public space, the unit is shown on the permit's site plan.
What does Montgomery County require?
The county's Department of Permitting Services requires a special event permit for events that generate or invite public participation or spectators and affect public streets, sidewalks or nearby properties.
Bethesda, Silver Spring, Takoma Park and Chevy Chase, Maryland all sit in Montgomery County, and an event in those places that affects public space needs the county's special event permit. Other county permits may also apply. No county rule on portable toilets was found, so the organiser confirms the restroom arrangements with the Department before the unit is booked.
Takoma Park is a city with its own municipal permits, and an event there follows the city's route as well as the county's where both apply.
What about Prince George's County?
No Prince George's County rule for portable toilets was found. The towns and cities inside the county have their own municipal permits, and the spot is checked with the town or city before the booking.
Hyattsville, College Park, Riverdale Park, Greenbelt, Bowie and Brentwood each have their own municipal government, and the county government covers the rest of the county, including Upper Marlboro, the county seat. The provider confirms the place and its permit route before booking. The organiser asks the town or county office to confirm the portable toilet requirement, since no sourced rule was found.
Lanham is an unincorporated community in the county, and its events go through the county's own routes.
Why does the District's rule not apply across the line?
Each jurisdiction sets its own rules for its own streets, parks and events. The District's permits and the MSETG review do not apply to a unit placed in a Virginia or Maryland jurisdiction.
The District's special event review and its public space rules cover the District only. A unit in Arlington or in Montgomery County is governed by the rules of that county or city. The provider checks the spot against the right jurisdiction, and it does not carry a District permit across the line as if it applied.
A route that crosses the line needs both sets of rules for the parts of the route in each place.
