How many accessible portable toilets does a Houston event need?
The Houston special-event sheet asks for portable toilets at 1 per 300 persons of projected attendance, with 10 percent wheelchair accessible. For 3,000 people that is 10 units, with 1 accessible. Smaller events round up, since a unit cannot be split. Confirm the count with the permit office for your event.
The numbers are the City of Houston's starting count for producers and they apply to events that go through the city process. They are not the limit of what is sensible. A parade viewing area where many older guests stand for hours may call for a larger share of accessible units than the sheet's bare 10 percent.
If your event is in one of the independent cities, such as Bellaire, Pasadena or Missouri City, the permit process is the local city's, not Houston's. Ask the city or the property owner what applies. This call line gives no city-specific rules for those places, and it cannot tell you whether a unit satisfies any accessibility requirement.
Where should an accessible unit be placed on a site?
Place it on a firm, level surface close to the main entrance, with a clear path to the door and no steps, cables or loose gravel in the way. Houston city park guidelines put units on or near pavement; on private land, you and the provider's driver choose a similar spot.
A ramp does not help if it ends in soft grass. Houston's park guidelines call for units on or about a paved surface at a spot chosen by Houston Parks and Recreation staff. That rule is for city park permits only, but the idea carries over to any site: pavement under the ramp, space in front of the door, and a path that a wheelchair can follow from where guests arrive.
Walk the route before the event. Look at where the units sit relative to the stage, the food area and the parking, and ask a person who uses a wheelchair to look at the plan if you can. Moving a unit after guests arrive is the provider's job and takes time.
Do accessible units work in Houston heat and rain?
They work, with the same limits as any plain unit: an enclosed cabin in direct sun gets hot, and a soft lawn can defeat a ramp after rain. Ask for a shaded, paved spot, and consider a trailer for guests who need more comfort during long summer events.
Houston has issued repeated heat advisories, with temperatures at or above 105 F and a heat index near 112 F. A guest who has limited mobility and cannot leave quickly feels that more than most. At a long summer event, an accessible stall inside an air-conditioned trailer is a considerate option when the provider has one.
Rain matters in a different way. A wet field can soak a ramp's base and make a wheelchair route impassable. If the forecast turns, tell the provider so the driver can adjust the placement before the delivery.
