How many stalls does a wedding need?
Work the number from the busiest hour of the event, then check it against the city's ratio and the parks department's figure. The provider and the permitting office settle the final number together.
City guidance works to about one toilet per 50 people at expected peak attendance, and it recommends that 5 to 10 percent of the units be ADA-accessible. The parks department applies a lower figure on its own special-request form, and it decides whether temporary toilets are required. Those two sources do not agree, so the count is confirmed with the permitting office instead of being treated as a single rule.
The guest list is only the start. A wedding with a long cocktail hour and a short ceremony puts the load on the bar and lawn area, and a wedding with a late reception puts it on the last hour.
Does a wedding trailer need a permit?
It depends on where the venue is. A venue inside Austin follows the city's process, and a venue outside the city follows the county or the nearby city that arranges events in its limits.
Events in West Lake Hills, Pflugerville, Manor and Buda are arranged with that city. Events in unincorporated Travis County are arranged with the county, and the county's mass-gathering permit asks for a signed contract with the toilet provider, a site plan that shows each toilet's location labeled for men or women, and handwashing stations with running water.
The state definition of a mass gathering applies to events held outside a municipality. It starts at more than 2,500 people, or more than 500 where under-21s and alcohol conditions apply, and it covers events lasting more than five continuous hours or running into 10 pm to 4 am.
Can a trailer sit on a septic property?
Yes, as long as the trailer is self-contained and nothing is connected to the septic system. The handwashing wastewater goes to a holding tank that the provider empties, not to the drain field.
A venue on a septic system, rather than a public sewer, needs the trailer to hold its own waste. A restroom trailer keeps its waste in its own holding tank, and the handwashing water is held the same way. The state standard for mass gatherings allows wastewater to go to holding tanks or to subsurface absorption, and for a trailer the holding tank is the practical choice.
A septic drain field should not take event loads. Event use can overload a small system, and a field that is saturated after rain can fail under a crowd.
What moves the price of a wedding trailer?
Trailer size, the number of stalls and sinks, how long it stays, how often it is serviced, how far the venue is from the provider's yard, and whether the truck can turn at the placement. The price is explained and approved before work starts.
The biggest single factor is access. A venue where the truck can turn at the pad is quicker to set and to pick up, and a venue with a long narrow drive, a low gate or a soft lawn takes more time at both ends. Hill-country venues with long drives add time on the road as well as on the site.
The provider confirms the price for the venue before delivery. No figure is given on this page, because a figure depends on the trailer, the dates and the site, and only the provider can state it for a particular job.
Where should a trailer go on the day?
On level ground, close to the guest route, away from low ground and from the drain field, with room for the truck to turn in and out.
Placement works best when the trailer is in view of the reception but not in the photographs. A spot at the edge of the lawn, behind a line of trees, is often the right answer, provided the route from the reception to the trailer is firm and lit enough for guests to use after dark.
The heat matters for placement. In an average year Austin has about 29 days at 100 degrees Fahrenheit or hotter, and a trailer set in full sun on a June afternoon gets hot inside.
