Construction Porta Potty Rental in Madison, WI

Conditions for Job Sites

New Housing

About 14.3% of Madison'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.

Homes From the 1970s and 1980s

The median year built for Madison's housing is 1980 (ACS 2020–2024), newer than most U.S. places in our data. Housing from that era is now 35 to 55 years old; crews replacing roofs, windows or mechanical systems on it need a toilet on site like any other crew.

Apartments, Townhouses and Rentals

The most common housing type is buildings with five or more units, about 44% of units (higher than nine in ten U.S. places in our data), followed by detached houses at about 40% (ACS 2020–2024). Apartment and condo projects bring larger crews, and a property manager decides where units go. About 54% of occupied homes are renter-occupied (ACS; owner share lower than nine in ten U.S. places in our data), so property managers and landlords often book the units for renovations and decide where they stand.

DOE's Building America map puts Dane County in the Cold climate region (IECC 2021 zone 5A, 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 147 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 52 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.

Lead-Safe Renovation

About 51% of housing units predate 1980 (ACS 2020–2024). Under OSHA’s lead standard (29 CFR 1926.62), workers exposed to lead need adequate hand-washing facilities, and EPA’s RRP Rule covers paint-disturbing work in homes built before 1978; add hand-wash stations to the order on those jobs.

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.

Who to Ask About Local Rules

Madison 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 Madison city government before you book what applies.

If you rent your home, check with the landlord or property manager before a unit goes on the property.
