Conditions at a Glance
Climate figures: NOAA 1991–2020 normals from the Boise Air Terminal, ID station, about 16 miles away. Conditions on your site can differ from the station's.
Conditions for Job Sites
New Housing
About 22.4% of Nampa's housing units were built in 2010 or later (ACS 2020–2024), about 2.0 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 7.4% were built in 2020 or later, in the top tenth of U.S. places in our data.
Newer Homes
Half of Nampa's housing units were built in 2000 or later (median year built, ACS 2020–2024), newer than three in four 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 75% of units (higher than most U.S. places in our data), followed by two- to four-unit buildings at about 9% (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 70% 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.
The closest NOAA climate-normals station, Boise Air Terminal, ID, is about 16 miles from Nampa'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.
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. Freezing nights are routine in winter; ask whether the provider changes its service approach for winter job sites. 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. On hot-spell weeks, an extra service visit keeps units usable for the crew.
How Many Toilets
OSHA 29 CFR 1926.51(c)(1) sets the minimum number of toilets on a construction site by headcount:
| Number of employees | Minimum toilet facilities |
|---|---|
| 20 or fewer | 1 toilet |
| 20 or more | 1 toilet seat and 1 urinal per 40 workers |
| 200 or more | 1 toilet seat and 1 urinal per 50 workers |
Worked examples, rounding up as the table is usually read: 15 workers need 1 toilet. 45 workers need 2 toilet seats and 2 urinals (45 ÷ 40 = 1.125, rounded up to 2). 210 workers need 5 seats and 5 urinals (210 ÷ 50 = 4.2, rounded up to 5).
On a subdivision with three crews of 15 working at once, count all 45: that is 2 toilet seats and 2 urinals, not one unit per crew.
Servicing frequency is set with the provider when you book; tell us headcount and shift length. OSHA's job-site toilet table has the full table.
Placement and Access
Put units on firm, level ground the service truck can reach, close to where crews work, clear of crane swing, excavation and vehicle routes, and move them as the work moves.
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. Stake units on open lots or set them against a structure, and keep them away from dust thrown up by grading.
Federal OSHA or State Plan
Idaho is not an OSHA-approved State Plan state: federal OSHA covers most private-sector workers there (osha.gov State Plans, accessed 2026-10-13), so 29 CFR 1926.51 is the toilet rule for private job sites. State and local government workers are not covered by federal OSHA.
Who to Ask About Local Rules
Nampa is an incorporated city with its own municipal government. For a unit placed in the street, on a sidewalk or in another public right-of-way next to the job site, ask the Nampa city government before you book what applies.
What to Ask For
- Crew size at the busiest point and shift length (OSHA sets the minimum by headcount)
- Rental term and service frequency
- A spot on site the service truck can reach
- Whether units need to move as the work progresses
- Winter servicing and freeze protection for holding tanks

Does Idaho use federal OSHA or a State Plan?

Can job-site units stay out all winter in Nampa?
Yes, standard units have no running water to freeze, but with about 108 nights a year at or below 32°F, ask how the provider services them in winter and protects any hand-wash stations.
