Weather and Building Across the State
Heat
Torrington has the most hot days of all 17 Wyoming places listed here: about 53 days a year at or above 90°F (NOAA normals, Torrington Muni. Airport, WY station). None of the 17 listed places reach 90°F on 60 or more days a year. For most of the state, heat is a summer-month issue rather than a constant one.
Freezing Nights and Snow
Jackson has the most freezing nights of all 17 Wyoming places listed here: about 235 nights a year at or below 32°F (NOAA normals, Moose 1 NNE, WY station). All 17 listed places average 120 or more freezing nights, when water-carrying units need winterizing or heat for months at a time. Lander has the most snowfall of the 7 listed Wyoming places with this figure: about 88 inches of snow a year (NOAA normals, Lander Hunt Field Airport, WY station). All 7 places with snowfall normals average 20 inches or more, enough to plan for a plowed path to the units.
Rain
Powell has the least precipitation of all 17 Wyoming places listed here: about 6 inches of precipitation a year (NOAA normals, Lovell, WY station). 14 of 17 listed places get under 15 inches a year: firm, dry ground, but wind and dust on open sites, so ask for units to be staked.
New and Older Housing
Ranchettes has the highest share of recent housing of the 16 listed Wyoming places with this figure: 16.5% of housing units built in 2010 or later (ACS 2020–2024). 9 of 16 listed places are above the U.S. share of 11.4%. That describes the housing stock, not current permits, but it shows where new-home construction has been concentrated; OSHA's toilet table applies to every one of those job sites. Torrington has the oldest housing of all 17 Wyoming places listed here: a median year built of 1966 (ACS 2020–2024). 1 of 17 listed places have a median year built of 1970 or earlier, where renovation crews in existing buildings are the usual job site.
Climate Regions
Listed places by DOE Building America climate region (county-level, PNNL guide to IECC 2021 zones): Cold (16), Very cold (1). A state spanning several regions means the right advice depends on the city, which is why each city page has its own figures.
Job-Site Toilet Rules: Federal OSHA or State Plan
Wyoming runs an OSHA-approved State Plan, Wyoming Occupational Safety and Health Administration (Wyoming OSHA), Wyoming Department of Workforce Services, that covers most private-sector workers as well as state and local government workers (osha.gov State Plans, accessed 2026-10-13). State Plans must be at least as effective as federal OSHA, so check the State Plan's construction sanitation rule alongside 29 CFR 1926.51.
The federal minimum, OSHA 29 CFR 1926.51(c), is one toilet for 20 or fewer workers, then one toilet seat and one urinal per 40 workers, or per 50 at 200 or more. Sizing details: construction rentals in Wyoming.
Who Handles Event and Street-Use Rules
Of the 17 Wyoming places listed here, 16 are incorporated cities, towns, villages or boroughs and 1 are Census-designated places, unincorporated communities without a municipal government. The rule of thumb for an event on public land or a unit on a street or sidewalk: in an incorporated place, ask the city, town, village or borough government; in an unincorporated community, ask the county. We do not say whether a permit is needed; each city page names who to ask.
