Caldwell at a Glance
Climate figures: NOAA 1991–2020 normals from the Boise Air Terminal, ID station, about 22 miles away. Conditions on your site can differ from the station's.
Planning Around the Weather
The closest NOAA climate-normals station, Boise Air Terminal, ID, is about 22 miles from Caldwell's Census point, far enough that conditions on your site can differ; treat the 1991–2020 normals below as a guide. DOE's Building America map puts Canyon County in the Cold climate region (IECC 2021 zone 5B, PNNL county guide). Winters in this region are long enough that freezing, not heat, is usually the main limit on units that carry water.
Dry, Windy Sites
Only about 12 inches of precipitation falls in an average year, in the driest tenth of U.S. places in our data. Dry ground usually holds a truck and a wheelchair well, but open, dry sites can get windy and dusty: ask for units to be staked or tied down on exposed ground.
Freezing Nights
About 108 nights a year reach 32°F or below, more than most U.S. places in our data, mostly between late fall and early spring. Water-carrying units need a plan from late fall into spring: give your dates when you call and ask how hand-wash water and flush tanks are kept from freezing. Snow is light, about 18 inches in an average year.
Summer Hot Spells
About 55 days a year reach 90°F, more than most U.S. places in our data; hot spells come and go rather than lasting all summer. If your dates land in a hot spell, ask for an extra service visit on multi-day rentals and keep hand-wash stations topped up.
Job Sites and Home Projects
New Housing
About 31.8% of Caldwell's housing units were built in 2010 or later (ACS 2020–2024), about 2.8 times the U.S. share of 11.4% and higher than nine in ten U.S. places in our data. Projects that build in phases can move units as each phase finishes; ask for relocation as a service visit when you book. About 6.8% were built in 2020 or later, in the top tenth of U.S. places in our data.
Newer Homes
Half of Caldwell's housing units were built in 2003 or later (median year built, ACS 2020–2024), newer than nine in ten U.S. places in our data. Newer lots often have a driveway the truck can reach, which makes it easier to place a unit for additions, pools or landscaping work.
Housing Mix
The most common housing type is detached houses, about 79% of units (higher than three in four U.S. places in our data), followed by two- to four-unit buildings at about 6% (ACS 2020–2024). Detached houses usually have a driveway or yard where a crew's unit can stand within reach of the service truck. In small multi-unit buildings where tenants stay in place during work, put the crew's unit where it does not block a shared entrance. About 73% of occupied homes are owner-occupied (higher than most U.S. places in our data); for a rented home, the landlord's OK comes before the unit.
OSHA 29 CFR 1926.51 counts everyone on site at once: three crews of 15 make 45 workers, which means 2 toilet seats and 2 urinals, not one unit per crew. More on sizing: construction rentals in Idaho.
Events, Weddings and Parties
An all-day festival for 5,000 people over six hours needs 38 units on the PSAI event chart, or 42 to 46 with alcohol (PSAI adds 10–20%). Every cluster of restrooms needs at least 5% accessible units, rounded up; hard, dry ground usually works as the route to the ADA unit, loose sand or gravel does not.
Cold, not heat, limits the outdoor season: from late fall into spring, ask for a heated restroom trailer or units that do not depend on running water. At open-field events on dry, exposed ground, ask for units to be staked. For a backyard party at a house, you can ask for a single unit; a deluxe flushable unit needs no hookups.

Who to Ask About Local Rules
Caldwell is an incorporated city with its own municipal government. For an event on public land, or a unit that will stand on a street, sidewalk or in a park, ask the Caldwell city government before you book what applies.

What weather should I plan for in Caldwell?

The station is more than 15 miles away, so your site can differ. Plan for dry, open ground first: stake units on windy sites.

Who do I ask about a permit for an event or a unit on the street in Caldwell?
Ask the Caldwell city government. Its special-events or street-use office can say what applies to your date.
What affects the price of a porta potty rental?
Unit type, number of units, rental length, servicing frequency and how easy the site is to reach. The provider quotes before you book.
