Roadwork crews move along the street, so the restroom has to move with them or sit within reach of every work zone. Construction toilet rules count the workers on the job, and a unit too far away may not count as provided. A technician places and moves units with the crew lead. The price is explained and approved before work starts.
The city resurfaces streets every year. The annual resurfacing program paved 36 streets in spring 2026, and the capital budget behind that work covers street resurfacing alongside other capital projects. A resurfacing crew does not stay in one place. It works one block, then the next, with milling machines, rollers and trucks, and it needs a toilet within reach of wherever it is working on a given day.
Utility crews work the same way. They open a trench for a line, backfill it and move to the next stretch of street. The OSHA construction rules do not depend on whether the crew is laying asphalt or running a line, since they count the people working on the job. Work of this kind generally falls under the construction toilet rule in 29 CFR 1926.51, so the toilet count and the washing facilities follow from the number of workers and how far the nearest toilet is.
This page covers how a technician places units for a moving crew, how the OSHA mobile-crew provision works and where it stops, how handwashing is set up, and what a resurfacing or utility job needs from its schedule. It is written for the crew lead and for whoever sets the work zones. The construction toilet guide explains the federal rule in full, and the construction site page covers stationary crews.
Do not set a unit in a travel lane, on a curb cut or on a grade that could tip it, and do not stand a unit at the edge of a trench. A unit left full in a closed zone should be serviced or removed before the crew returns, and a unit blocking a sidewalk or a crosswalk should be moved at once. The crew should keep hoses and pump lines clear of the paving equipment, since a line that is run over can spill.
The technician asks for the block-by-block schedule, the number of workers in each zone and the days each zone is open. A moving crew is planned by zone rather than by address, so the placement follows the map. Where two crews work the same week, each one is counted, even if they share a unit.
The minimum toilet count comes from the number of workers in the zone at one time. Under the OSHA table, one facility covers twenty or fewer workers, and above that a toilet seat and a urinal are added for each forty. The count for each zone is written into the plan, and the peak day sets the count for that week.
A moving crew needs a unit close enough to reach on its break. The OSHA exemption for mobile crews depends on transportation being readily available to nearby toilets, and an OSHA letter indicates that toilets too slow to reach are not counted as provided. The unit is set on a pull-off or the curb side, out of traffic, with room for the service truck to stop beside it.
When the crew moves to the next block, the unit moves too. The move is scheduled with the crew lead, the old spot is cleared, and the new spot is checked for firm, level ground before the unit goes down. A unit left behind in a closed zone is hard to reach for the crew that still needs it, and it is removed once the zone is finished.
Washing facilities are required on construction sites under 1926.51(f), so a handwash station sits beside the units and moves with them. Units are pumped on the schedule set for the crew's size, and a full unit is replaced rather than left in use. The handwash station is refilled before each shift, since an empty station defeats the rule's purpose.
Not necessarily on every block, but a toilet has to be provided at the site, and a unit too far away does not count as provided.
Under the OSHA construction rule, a mobile crew may rely on nearby toilets when transportation to them is readily available, and an OSHA letter indicates that toilets which take too long to reach are not counted as provided. The rule does not set a minute figure, so there is no number to quote. The test is whether the crew can reach a unit during its break without leaving the work zone or walking through traffic.
When the answer is no, a unit goes into the zone. A technician sets the count and the location with the crew lead and writes both down, so the next crew to take over the zone does not inherit an unplaced count.
The count is the number of workers at the peak of the day, using the OSHA tiers for construction work.
The construction table counts the workers on the site: one facility for twenty or fewer, and seats and urinals above that for every forty. A paving crew that peaks higher on one day sets the count for that week, even if the average is lower. The technician plans from the peak, not the average, and adds a unit where the crew would otherwise queue.
Units used only by construction personnel fall outside the federal accessibility guidance for public-use units.
Federal guidance quoted by the Justice Department and the Access Board requires at least 5 percent of clustered single-user units to be accessible for public use, and never fewer than one per cluster. That guidance is not a Columbus rule. Portable toilets used at construction sites exclusively by construction personnel are fully exempt from it.
If the work runs beside a pedestrian route, a park or a busy public frontage, the site owner or the city should say whether the units there count as public use. The question is settled before the placement is set, so an accessible unit is not added after the crew has already moved on.
Construction sites need washing facilities under the OSHA rule, and a handwash station can move with the crew and the units.
Under 1926.51(f), washing facilities are required on construction sites. A handwash station goes beside the units and moves with them, and it is refilled before each shift. A crew that works through a dusty or muddy shift uses the station more than a crew on a dry day, so the refill schedule follows the crew's use.
The station needs a level spot and a route for the service truck, the same as a unit does. Setting the station and the units in the same visit saves a stop on the route, and the technician checks both on each move.
The price is explained and approved before work starts, and the largest factor is the number of zones and moves, since each move is a truck visit.
The number of zones and the number of moves are the largest factors for a moving crew. Other factors include how many units the peak crew needs, how long the job runs, how far the truck drives between zones, how much ground preparation the placement needs and whether any unit must be accessible. Each of those is set on the zone map before the quote.
No figure is published on this page. The local provider quotes each job from the zone map, and the quote is explained before the first unit goes down. Ask for the zone moves and the service visits to be listed separately, so the scope is clear.
A paving crew works one block at a time over a few days. Units are placed at the end of each block, near the crew's staging area, and moved each time the work moves. The crew is usually counted as one zone, and the count is set by the workers on the day with the most people, not by the average.
A utility crew digs and backfills in a narrow corridor and may run several trenches at once. Units go at the staging point or a pull-off where the truck can reach them, rather than inside the trench zone. Where a crew is mobile and transportation to a nearby toilet is readily available, the mobile-crew provision in 1926.51(c)(4) may apply, but the nearby toilet has to be reachable in practice.
Where a crew stays at one site for several weeks, the arrangement looks more like a construction site. A unit is placed on a firm pad close to the work, serviced on a fixed schedule and counted under the OSHA tiers for the workers on the pad. The construction site page covers this arrangement in more detail.
The city's annual resurfacing program paved 36 streets in spring 2026, according to reports of the program. A program of that size moves through the city in zones over the year, and a crew of that kind needs its units placed by zone, not at one fixed site. The Columbus area page covers the city's core streets.
Work on a major road usually runs under lane closures, with the crew in a corridor between the traffic and the curb. The unit goes at the edge of that corridor, not in the travel lane, and the truck needs a pull-off close enough to service it without blocking traffic. The Groveport area page covers the south side, where crews work along the warehouse belt roads.
Downtown and the Scioto corridor have dense traffic and tight staging areas, so units are set where a service truck can pull off without blocking a lane. A crew working near the river or the creeks also needs the unit kept off drainage paths, so that runoff from the work does not flow into the unit's base. Placement in those areas is agreed with the crew lead on the zone walk.

Single-unit portable toilet rental for job sites, yards, and events across Columbus and Franklin County.
How a unit is delivered, leveled and placed in Columbus and Franklin County so the service truck can reach it for every pump-out.
In Ohio, the waste in a portable toilet is treated as sewage and septage, and only a registered septage hauler may pump it.
The right rental term depends on how long the site runs, how many people use the unit and how often it needs to be emptied.
The phone line is answered 24 hours a day. A visit the same day happens only when a technician is free, and no arrival time is promised. Give the zone map and the start date at booking so the unit is planned in advance.
A unit only counts for crews close enough to reach it on a break. Two crews on separate blocks need their own units, placed where each crew can reach them without leaving its zone.
The technician and the crew lead choose the spot on the zone walk. Any unit placed in a public street or lane is cleared with whoever controls that street before it goes down.
Units used only by construction personnel are exempt from the federal public-use guidance. If the work is beside a public route or park, the site owner or the city should say whether the units there count as public use.
The move is scheduled with the crew lead. The old spot is cleared, the new spot is checked for firm, level ground, and the unit is set and checked before the crew uses it again.
