Weather and Building Across the State

Heat

Delavan has the most hot days of all 156 Wisconsin places listed here: about 21 days a year at or above 90°F (NOAA normals, Lake Geneva WWTP, WI station). None of the 156 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

Ashland has the most freezing nights of all 156 Wisconsin places listed here: about 185 nights a year at or below 32°F (NOAA normals, Ashland Kennedy Mem. Airport, WI station). All 156 listed places average 120 or more freezing nights, when water-carrying units need winterizing or heat for months at a time. Superior has the most snowfall of the 97 listed Wisconsin places with this figure: about 90 inches of snow a year (NOAA normals, Duluth, MN station). All 97 places with snowfall normals average 20 inches or more, enough to plan for a plowed path to the units.

Rain

Monroe has the most precipitation of all 156 Wisconsin places listed here: about 38 inches of precipitation a year (NOAA normals, Brodhead WWTP, WI station). None of the listed places reaches the wet band (46 inches or 12 days with an inch), so rain is a day-of-event issue rather than a seasonal one.

New and Older Housing

Hobart has the highest share of recent housing of the 147 listed Wisconsin places with this figure: 45.2% of housing units built in 2010 or later (ACS 2020–2024). 51 of 147 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. Shorewood has the oldest housing of the 153 listed Wisconsin places with this figure: a median year built of 1939 or earlier (ACS 2020–2024). 48 of 153 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 (156). Winters in this region are long enough that freezing, not heat, is usually the main limit on units that carry water.

Shoreline Places

20 of 156 listed places have a Census reference point within 5 km (about 3 miles) of the shoreline in the TIGER coastline layer, which includes Great Lakes shores. Beach and waterfront sites need a firm approach for trucks and a firm route for ADA units.

Job-Site Toilet Rules: Federal OSHA or State Plan

Wisconsin 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), 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 Wisconsin.

Who Handles Event and Street-Use Rules

Of the 156 Wisconsin places listed here, 154 are incorporated cities, towns, villages or boroughs and 2 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 town or township it sits in, or the county. We do not say whether a permit is needed; each city page names who to ask.

Questions About Renting in Wisconsin

My town isn't listed. Can I still call?

Yes. 156 Wisconsin places have their own page because they have published Census and NOAA figures, but we take calls for any address in Wisconsin. Call (888) 417-6737, answered 24/7. Tell us the units you want; the provider confirms what's available for your site.

What weather matters most for rentals in Wisconsin?

Freezing nights: All 156 listed places average 120 or more a year at 32°F, so hand-wash stations, deluxe flush tanks and trailers need winterizing or heat in the cold months. (NOAA 1991–2020 normals.)

Does Wisconsin use federal OSHA or a State Plan for job sites?

Wisconsin 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.

What about sites near the Wisconsin border?

Call the same number. Several listed Wisconsin places have towns in Minnesota, Illinois, Iowa, Michigan among their nearest neighbours; we connect you with a provider that serves the site's actual address, in whichever state it is.

How many porta potties do I need?

For events, the PSAI chart sizes units by crowd and hours; for job sites, OSHA 1926.51 sets the minimum by headcount; and at least 5% of each cluster should be ADA-accessible.

Don't know where to start?
