How many stalls does a wedding need?
A common starting point is to match stalls to the guest count and the length of the event, but there is no single rule for private parties. The provider suggests a size from your headcount, hours and whether the party includes a long cocktail hour or open bar.
The Maricopa County code sets a minimum of one toilet per 100 attendees at public gatherings without enough permanent toilets, but a private wedding is a different category and the county's special event rules apply to events where food is sold or given away. Check which applies to you, and treat the number as a floor, not a target.
For comfort, plan above the minimum. A queue at a wedding builds fast after the ceremony and dinner. Ask the provider how many stalls would keep the wait short, and do not skimp if the party runs late.
Where should the trailer go on a private lot?
Put it on firm, level ground that the tow vehicle can reach, close to the party but away from the ceremony and the dining area. Check gates, overhead branches and sprinklers. Shade on the entrance side makes it more pleasant, and a lit path helps after dark.
Large lots in Paradise Valley, Scottsdale and Ahwatukee often have long drives, desert landscaping and irrigation lines. Tell the provider where those are. A tow vehicle on a soft verge or over a sprinkler line can do damage that is expensive to fix, so mark the route.
Photographers will thank you for putting the trailer behind a wall, a hedge or a corner of the house. Guests will thank you for a sign, a lit path and a mat on loose gravel.
Is there anything to check with the town or the venue first?
Yes. Private lots can have homeowner association rules, and towns can have their own event or noise rules. We have not confirmed rules for individual Valley towns, so ask your town or the venue whether a trailer, a generator and overnight parking are allowed.
For a rented venue, ask the venue manager what is allowed. Some venues have their own preferred arrangements, and some require vendors to carry specific paperwork. Pass any request to the provider through the line, since it is the provider that holds the trailer and answers for it.
Tell neighbors if a generator will run. A trailer on a power hookup is quieter, so ask whether the property has an outlet that suits it.
What details make guests comfortable?
A lit path, a clear sign, a mat at the door, steady handrails, soap and towels, and a trailer cool enough to be pleasant. Ask the provider what the trailer includes, and tell it about any extras you plan to add such as flowers or a scented candle.
Guests notice small things. A step that wobbles, a dark path or a trailer that smells of chemicals will be remembered longer than the flowers. Ask the provider about its cleaning routine before the event, and about whether it can restock during a long reception.
If your guest list has older relatives or small children, ask about a lower step or a handrail. Do not place anything fragile or flammable inside the trailer, and keep candles and open flames well away.
