Hermiston at a Glance
Climate figures: NOAA 1991–2020 normals from the Hermiston Muni Ap, OR station, about 1 miles away.
Planning Around the Weather
DOE's Building America map puts Umatilla 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 9 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 115 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.
Summer Hot Spells
About 50 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 12.8% of Hermiston's housing units were built in 2010 or later (ACS 2020–2024), above the U.S. share of 11.4% and higher than most U.S. places in our data: newer construction sits alongside older stock, so job sites range from new homes to additions and repairs.
Homes From the 1970s and 1980s
The median year built for Hermiston's housing is 1986 (ACS 2020–2024), newer than most U.S. places in our data. Housing from that era is now 35 to 55 years old; crews replacing roofs, windows or mechanical systems on it need a toilet on site like any other crew.
Older Paint on Renovation Jobs
A large share of Hermiston's housing, about 43% of units, was built before 1980 (ACS 2020–2024). EPA’s Renovation, Repair and Painting Rule covers paid work that disturbs painted surfaces in homes built before 1978, and OSHA’s lead standard for construction (29 CFR 1926.62) requires adequate hand-washing facilities for workers exposed to lead. If the crew will sand, scrape or demolish old paint, put one of the hand-wash stations next to the toilet.
Mobile Homes
The most common housing type is detached houses, about 57% of units (lower than most U.S. places in our data), followed by buildings with five or more units at about 15% (ACS 2020–2024). Detached houses usually have a driveway or yard where a crew's unit can stand within reach of the service truck. Apartment and condo projects bring larger crews, and a property manager decides where units go. In a manufactured-home community, the community's management decides where a unit for setup or repair work can stand. About 38% of occupied homes are rented (owner share lower than most U.S. places in our data), so check who controls the property before a unit goes on it.
OSHA 29 CFR 1926.51 sets the floor: one toilet for up to 20 workers, then a seat and a urinal per 40 (per 50 at 200 or more). More on sizing: construction rentals in Oregon.
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. More: event rentals in Oregon and wedding restrooms in Oregon.
Who to Ask About Local Rules
Hermiston 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 Hermiston city government before you book what applies.
In a manufactured-home community, ask the community's management first.
