Conditions at a Glance
Climate figures: NOAA 1991–2020 normals from the Denver-Stapleton, CO station, about 12 miles away.
Conditions for Job Sites
New Housing
About 18.5% of Thornton's housing units were built in 2010 or later (ACS 2020–2024), above the U.S. share of 11.4% and higher than three in four U.S. places in our data: newer construction sits alongside older stock, so job sites range from new homes to additions and repairs.
Housing Mix
The most common housing type is detached houses, about 62% of units (lower than most U.S. places in our data), followed by buildings with five or more units at about 20% (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. About 71% 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.
DOE's Building America map puts Adams 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 156 nights a year drop to 32°F or below, more than nine in ten U.S. places in our data, so freezing weather covers a large part of the year. Winter job sites need units that keep working through months of freezing nights: ask how the provider keeps holding tanks and any hand-wash water from freezing between service visits.
Snow and Access
Average snowfall is about 49 inches a year, more than three in four U.S. places in our data, enough to bury a ground-level path several times a winter. Make the units' spot part of the site's snow plan: plowed snow piled against units blocks doors and the service truck's access.
Summer Hot Spells
About 42 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).
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.
Federal OSHA or State Plan
Colorado 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
Thornton 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 Thornton 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
- Who plows the truck's path to the units
