Washington Conditions That Matter for Restroom Trailers
Across the 189 Washington places listed here (NOAA 1991–2020 normals by nearest station):
- 88 of 189 listed places average 30+ freezing nights, 22 of them 120+
- None of the 189 listed places average 60+ days at 90°F
- 13 of 26 places with snowfall data average 20+ inches of snow
Freezing nights are limited in much of the state, so the power supply for lights, pumps and air conditioning is usually the bigger planning item.
Range Across the State
Across the 189 listed Washington places with this figure (NOAA 1991–2020 normals), the low end is about 21 nights a year at 32°F or below (Tacoma, Lakewood and 21 other listed places) and the high end about 147 (Yakima, Toppenish and 3 other listed places); the middle place is near 29.
By Climate Region
By DOE Building America climate region (county level, PNNL guide), the planning focus shifts: Marine (154 places): soft ground for the tow vehicle in damp months; Cold (35 places): heat and protected water lines for much of the year.

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 13 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 189 listed Washington places, 119 are incorporated, 70 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
