Arizona Conditions That Matter for Job Sites

Across the 90 Arizona places listed here (NOAA 1991–2020 normals by nearest station, ACS 2020–2024):

• 37 of 70 listed places have more housing built since 2010 than the U.S. 11.4% (ACS)
• 8 of 90 listed places average 120+ freezing nights a year
• None of the 17 places with snowfall data average 20+ inches of snow

More than half of listed places have an above-U.S. share of recent housing; the figure describes the housing stock, but it points to subdivision-scale job sites where OSHA headcounts add up quickly.

Range Across the State

Across the 70 listed Arizona places with this figure (ACS 2020–2024), the low end is about 1.3% of housing units built 2010 or later (Sun City West) and the high end about 58.4% (Queen Creek); the middle place is near 12.1%.

By Climate Region

By DOE Building America climate region (county level, PNNL guide), the planning focus shifts: Hot-Dry (72 places): dust, wind and summer heat on open lots; Mixed-Dry (11 places): wind on open lots and freezing winters; Cold (7 places): months of freezing nights on winter jobs.

Federal OSHA or State Plan

Arizona runs an OSHA-approved State Plan, Arizona Division of Occupational Safety and Health (ADOSH), Industrial Commission of Arizona, 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)(1):

Worked examples: 15 workers need 1 toilet; 45 workers need 2 toilet seats and 2 urinals (45 ÷ 40 rounded up); 210 workers need 5 seats and 5 urinals (210 ÷ 50 rounded up).

Who Handles Local Rules

For a unit placed in the street, on a sidewalk or in another public right-of-way next to the job site, the government to ask depends on where the site is. Of the 90 listed Arizona places, 55 are incorporated, 35 are unincorporated Census-designated places. In an incorporated place, ask the city, town, village or borough; in an unincorporated community, ask the county. We don't say whether a permit is needed; each city page names who to ask.
