Power, Water and Space
Most trailers need power from an outlet or a generator, level ground, room to tow in and set up, and some need a water connection. Steps are not accessible; ask for a lift or ramp, or add an ADA unit beside the trailer.
In the 6 listed places averaging 20+ inches of snow, the tow path and pad need plowing before delivery and pickup.
Who Handles Local Rules
For a restroom trailer parked on a public street or in a public lot, or set up for an event on public land, the government to ask depends on where the site is. Of the 27 listed Montana places, 19 are incorporated, 8 are unincorporated Census-designated places. In an incorporated place, ask the city, town, village or borough; in an unincorporated community, ask the county. We don't say whether a permit is needed; each city page names who to ask.
What to Ask For
- Number of stalls for your headcount
- Power the trailer needs and who supplies the generator
- Whether it needs a fresh-water hookup
- Room to tow it in and level it
- Steps vs a lift or ramp for accessibility
