Madison conditions that change the order
Madison construction is heavily institutional, which means University of Wisconsin campus and Capitol-adjacent work with the access rules those bring. Campus sites frequently restrict service vehicle movement to specific hours and specific approaches, so the service window is dictated by the institution rather than by our route. Sizing tends to run above the OSHA floor here because these are long-duration projects where a compliance gap is more likely to be observed than on a short commercial job.
Access and placement in Madison
The isthmus is the defining constraint. Between Lake Mendota and Lake Monona the street grid is narrow, one-way, and heavily parked, and Capitol Square placements have to work around a permanent pedestrian ring. Course events like Ironman need units staged at intervals along public right-of-way, each requiring its own access window before roads close.
Madison covers roughly 278,001 residents across Dane County, with ZIP codes beginning at 53703. We place units around Camp Randall Stadium and Memorial Union Terrace, and through neighbourhoods including The Isthmus and Williamson Street. About 1 hour west of Waukesha via I-94.

How many units a Madison site actually needs
OSHA 29 CFR 1926.51(c) requires employers to provide adequate and readily accessible toilet facilities at every construction work location, with the minimum unit count set by the number of workers on site at any one time.
Worked example: a 45-worker Madison site
Take a job site off The Isthmus in Madison running a peak crew of 45. OSHA 29 CFR 1926.51(c) sets the floor at 2 units. That floor is a compliance minimum, not a service plan: a 60 to 70 gallon tank covers roughly a 10-person crew for a week, so 45 workers consume about 5 unit-weeks of capacity every week.
We would place 5 units and 3 hand-wash stations on weekly service, which comes to roughly $1,080 to $1,975 per month for that Madison site. Running the bare OSHA 2-unit minimum instead would technically satisfy the ratio, but the units would exceed capacity mid-week and stop counting toward compliance, because a soiled unit does not count.
Access shapes the placement more than the count does here. The isthmus is the defining constraint. About 1 hour west of Waukesha via I-94, which determines the service window your superintendent can plan around.

What you will pay in Madison
| Rental type | Price range | Basis |
|---|---|---|
| Monthly rental, 1x weekly service | $150 to $275 | per unit per month |
| Monthly rental, 2x weekly service | $240 to $425 | per unit per month |
| Winter monthly rental with antifreeze charging (December-March) | $195 to $340 | per unit per month |
| Hand-wash station paired to units | $110 to $200 | per station per month |
What moves the number
- Contract length, as multi-month job-site contracts price below month-to-month placements
- Peak simultaneous headcount, which sets the unit count under OSHA 29 CFR 1926.51(c) rather than the total project roster
- Service frequency, driven by crew size rather than the calendar: a 10-person crew fills a 60-gallon tank in about a week
Madison-specific factors
- Seasonal pressure specific to Madison: Dane County Farmers' Market on Capitol Square and Ironman Wisconsin concentrate regional inventory demand into a handful of weekends, and rates firm up accordingly.
- Cold-weather servicing follows the local freeze pattern rather than a calendar date. Dane County runs colder overnight than the Lake Michigan shoreline, so the antifreeze window here opens earlier and closes later than it does in Milwaukee.
- Placement difficulty affects labour time on every visit. Course events like Ironman need units staged at intervals along public right-of-way, each requiring its own access window before roads close.
Ranges reflect Wisconsin market rates observed in 2026 for delivery, weekly servicing, and pickup. Final pricing depends on unit type, service frequency, placement distance from our Waukesha dispatch point, and rental duration. Call for a firm quote.

What is the going rate for construction porta potty rental around Madison?
$150 to $275 per unit per month for a monthly rental, 1x weekly service, or $240 to $425 per unit per month for a monthly rental, 2x weekly service. About 1 hour west of Waukesha via I-94, and that distance is what decides whether a route surcharge is added. Madison sits on our regular Dane County run, so most placements here avoid one.
How many portable toilets does a Madison construction site need?
Take a job site off The Isthmus in Madison running a peak crew of 45. OSHA 29 CFR 1926.51(c) sets the floor at 2 units. That floor is a compliance minimum, not a service plan: a 60 to 70 gallon tank covers roughly a 10-person crew for a week, so 45 workers consume about 5 unit-weeks of capacity every week. Event organizers are responsible for restroom capacity beyond any permanent park facilities, and permanent park restrooms are frequently closed outside the summer season.
Do I need a permit for construction porta potty rental in Madison?
The unit itself is not permitted, but the activity it serves often is. In Madison that runs through the City of Madison Parks Division, Park Event Permit. Park event permits are issued through the Parks Division, with street-use events routed separately through the Street Use Staff Commission. Lead times lengthen sharply for Capitol Square and lakefront park dates. Fees vary by park, footprint, and whether alcohol or amplified sound is requested; confirm the current schedule with the Parks Division when you apply.
Which parts of Madison do you cover?
All of Madison and the wider Dane County area, covering ZIP codes 53703, 53704, 53705, 53711, 53713, 53715, 53717, 53719. We place regularly around Wisconsin State Capitol, Camp Randall Stadium, Memorial Union Terrace, and through The Isthmus, Williamson Street, Monroe Street. About 1 hour west of Waukesha via I-94.
How does cold weather affect a Madison placement?
Dane County runs colder overnight than the Lake Michigan shoreline, so the antifreeze window here opens earlier and closes later than it does in Milwaukee. Lakeshore park placements at Olbrich and along Lake Monona sit on ground that stays soft well into spring, and course-side units on terrace lawn need mats after wet weather. Antifreeze charging is added to each service visit through that window, and hand-wash stations come off site in favour of sanitiser dispensers until overnight lows clear freezing.
