Standard Portable Restrooms for Baltimore Events and Sites

What a standard unit is and where it fits

A standard unit is one enclosed restroom with a single door, a vent, a sealed tank and a hand sanitiser, and it stands on a footprint small enough for a sidewalk or a yard.

The unit is built to be moved, which makes it the right tool for a spot that changes from one weekend to the next. The walls are a moulded shell, the floor is sealed, and the holding tank sits below the seat so it can be emptied by a truck without anyone opening the unit. Most of what a guest sees is the door, the light and the hand sanitiser, and those are the parts a technician checks first.

A standard unit is not a permanent building and should not be treated as one. It needs level ground to stand properly, a clear route for the truck, and a little room around the door so the next person can get in without squeezing past the one before. A spot that works for one unit can fail for four, because the walkway and the turning space are what the crowd actually uses.

• Fits most sidewalks, side yards and event lots
• Needs firm, level ground for the footing
• Keeps a clear door swing and a short walk for guests
• Leaves the holding tank accessible to the truck

How many standard units does a party or job need?

Count by the hours and the crowd rather than by the guest list, and let a technician set the number, because the right answer depends on when people arrive and how long they stay.

A simple rule of thumb, used only as a starting point, is that the busiest hour decides the count. A three-hour afternoon party with a single cake break can run on two units. The same guests arriving together at a fixed time will queue for a unit, and a queue is what turns a pleasant afternoon into a complaint.

Baltimore's own guidance does not set a units-per-guest ratio for events, and this page does not invent one. The count is agreed with the organiser and the technician on the plan, using the date, the expected crowd, the hours and any food or drink service. Where a permit is involved, the restroom plan goes into the same file as the rest of the event plan.

Placement, footing and access on a Baltimore street

A unit has to stand where it does not block a door, a hydrant, a driveway or a fire lane, and it has to stand flat enough that the door closes on its own.

Baltimore's older blocks were not laid out for portable units. The footing is often brick, flagstone or uneven concrete, and a unit set on a slope will drift and let the door swing open. The technician looks at the footing first and levels the unit on a pad or with shims where the surface demands it.

Access matters as much as footing. A truck with a tank to pump has to reach the unit, turn and leave. On a narrow street that may mean a plan that uses a different curb cut or a shorter route. Tell us about parked cars, low branches and any gate that must stay open, and the plan will show where the truck can stand.

• Keep the door clear of steps, poles and parked cars
• Check for hydrants, driveways and fire lanes before placement
• Use a pad or shims on uneven brick or flagstone
• Confirm the truck route and the turning space

Servicing, cleaning and the day it is collected

A standard unit is serviced on a schedule set at booking, pumped when its tank is due, and collected when the rental ends, with the spot left as it was found.

For a single-day party the unit usually goes out and comes back without a servicing visit. For a multi-day job or a festival weekend the tank is pumped on a schedule, and the stock of paper, sanitiser and any cleaning supplies is checked on the same visit.

Pickup is planned as carefully as delivery. The crew needs to know where the unit stands, what time the spot must be clear and whether a permit requires the site to be cleared by a set hour. Once the unit is gone, the spot is checked, because a city or county office may ask for it to be left clean.
