California Conditions That Matter for Restroom Trailers

Across the 544 California places listed here (NOAA 1991–2020 normals by nearest station):

  • 63 of 544 listed places average 30+ freezing nights, 8 of them 120+
  • 224 of 544 listed places average 60+ days at 90°F
  • 1 of 60 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 544 listed California places with this figure (NOAA 1991–2020 normals), the low end is about 0 nights a year at 32°F or below (Los Angeles, Pasadena and 83 other listed places) and the high end about 222 (South Lake Tahoe); the middle place is near 4.

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 1 listed places averaging 20+ inches of snow, the tow path and pad need plowing before delivery and pickup.

In the 224 listed places with 60+ hot days, confirm the power supply covers the air conditioning.

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 544 listed California places, 351 are incorporated, 193 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
