Delaware Conditions That Matter for Job Sites

Across the 20 Delaware places listed here (NOAA 1991–2020 normals by nearest station, ACS 2020–2024):

• 6 of 17 listed places have more housing built since 2010 than the U.S. 11.4% (ACS)
• None of the 20 listed places average 120+ freezing nights a year
• All 16 places with snowfall data average 20+ inches of snow

Most listed places have a smaller share of recent housing than the U.S., so renovation crews in existing buildings are a common job-site type; OSHA's table applies to them too.

Range Across the State

Across the 17 listed Delaware places with this figure (ACS 2020–2024), the low end is about 0.3% of housing units built 2010 or later (Wilmington Manor) and the high end about 24.5% (Middletown); the middle place is near 9.0%.

By Climate Region

All listed Delaware places with a climate-region assignment fall in one DOE Building America region, Mixed-Humid (17 places): summer servicing and winter freeze protection.

Federal OSHA or State Plan

Delaware 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.

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 20 listed Delaware places, 10 are incorporated, 10 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.
