Convention and Expo Event Toilets in San Diego

How big is the outdoor crowd during convention week?

Comic-Con International reported more than 135,000 attendees over four days in 2022, and a different source said organizers cap attendance near 125,000. The free events around the Gaslamp Quarter and Petco Park add thousands more. The outdoor crowd depends on the program, so plan from your own event's footprint, not from the headline number.

Headline attendance counts people with badges, and your activation might draw a small part of that or a separate crowd altogether. Organizers of side events should estimate their own peak and discuss it with the permit office.

Petco Park is quoted at about 42,000 seats in some sources and 40,000 in others. The point for a rental plan is that it is a large venue with its own restrooms, and an overflow event adds people to streets that were not built for them.

What does a downtown permit conversation involve, and who controls the Convention Center?

Events on city streets or plazas go through the City of San Diego Office of Special Events, whose guideline is one toilet per 250 people at peak with 10 percent accessible. Private lots depend on the landlord, and the Convention Center operator controls its own halls and forecourts. Confirm the current rule with the right office.

The city guideline excuses an event from supplying toilets when the immediate area already has enough accessible and non-accessible public facilities. A plaza next to a convention hall may seem to qualify, but organizers should ask the permit office, not assume.

County rules apply for food: if the activation includes a food booth, the county's temporary food event checklist asks for one toilet per 15 food employees within 200 feet of the booth, with approved handwashing.

If your event is inside the center, the operator supplies the restrooms and sets the rules. If your event is next door, you are on someone else's ground. Know which before you call.

How do tight downtown blocks change placement?

Dense blocks leave little room, so cabins often go on a side street, a loading zone or a vacant lot with a barricade and a staff member. The provider needs the real width of the space, the turning room for a truck and a contact who can open a gate. A unit that does not fit the footprint will be moved, at a cost.

Downtown San Diego has fewer open fields than a suburb. A parking lot near the waterfront or a dirt lot between buildings can look generous on a map and feel cramped when a queue line is added. Check the plan against the lines you expect.

Neighbors matter. A hotel, a restaurant or a residential tower next to the cabins deserves notice, and a clear plan for noise, light and cleaning can prevent complaints.

What about crews who build and strike the event?

Setup and teardown crews can outnumber visitors on the days around a show, and they work long shifts on lots with no restrooms. Plan a separate small bank for crew, positioned where trucks can reach it, and count the days crews are on site, not just the days the public attends.

Load-in at a convention district begins days before the doors open. Riggers, electricians, builders and security staff arrive early and leave late, and they need toilets from the first morning. If the event is on a city site, Cal/OSHA's rule for employers of one toilet per 20 employees or fraction, per sex, may apply to the crews, so check with whoever employs them.

A crew bank can often be a few standard cabins and a handwash stand placed out of the public view. It should be on the booking from day one, not added when the first complaint arrives.

How do queue lines change the plan?

A queue line can hold thousands of people for hours on a sidewalk, and everyone in it is a potential toilet user who cannot leave without losing their place. Provide units along or at the end of the line, with a staff member to hold places, and tell the provider where the line forms.

The line is a moving crowd whose size changes by the hour, and its position changes as it fills. The organizer should plan for the line at its longest, and agree with the permit office how it will be routed so cabins are not blocked.

Some producers place a small bank where the line turns, so that no one is more than a short walk from a cabin. Others use cabins at the end of the line and a roaming volunteer to keep it moving. Both can work if the units are on level ground and visible.
