How many toilets does a job site need?
Start from the federal table in 29 CFR 1926.51(c)(1), counted against the number of workers on site at one time. The provider confirms the count for the site before delivery.
The table sets one facility for 20 or fewer workers. Above 20 it sets one toilet seat and one urinal per 40 workers, and at 200 or more it sets one toilet seat and one urinal per 50 workers. A widely repeated contractor figure of one toilet per 20 workers does not match this table, so the count is taken from the table itself and not from a rule of thumb.
The count should be checked against the shift overlap, the number of trades on site and any visitors who use the toilets. A site that counts only the day crew can be short during a change of shift, and the table applies to the workers who are actually on site, not to the total on the payroll.
What makes a unit count as provided?
A unit counts when workers can reach it in reasonable time and it is kept in sanitary condition. OSHA's interpretation letters say a unit that is too far away or dirty does not satisfy the requirement.
The distance test is practical. A unit at the far end of a large site, behind active equipment and a fence line, is not provided in the sense the table means, even though it is on the map. The placement is chosen so the walk from the work area is short enough that workers will actually use the unit.
The sanitary test is about servicing. A unit whose tank is full, whose floor is wet or whose door is propped open is not sanitary, and it does not count toward the minimum.
Does Austin add its own rules for job-site toilets?
Austin's rest-break ordinance was overturned by state law in 2023, and this page does not state what applies today. The city's general right-of-way rules apply to any unit placed on a sidewalk or a closed driveway.
The state law passed in June 2023, House Bill 2127, bars local rules stricter than state ones, and it overturned the city's construction-worker rest-break ordinance. The status of later litigation is not confirmed on this page, so the present-day rule is checked with the city or the state before it is relied on.
For a unit on a sidewalk or a driveway, the general right-of-way rules apply: a Temporary Use of Right of Way permit for a sidewalk or driveway closure, notice to 311 at least three days before a planned closure, and five feet of continuous pedestrian access where items sit on a sidewalk. No portable-toilet-specific right-of-way rule was found.
What moves the price for a construction site?
The number of units, how long the job runs, how often the units are serviced, how far the site is from the provider's yard, and whether the truck can reach the placement without a detour. The price is explained and approved before work starts.
Long jobs have a different cost shape from short ones. A site that runs for many months needs a fixed servicing route for the whole run, while a short job pays most of its cost in delivery and pickup. Access also moves the price: a site behind a gate with narrow lanes and materials stacked along the route takes more time at each visit.
No figure is given on this page. The price depends on the site, the headcount and the schedule, and the provider confirms it for the site before delivery.
Can a unit go in a tight downtown lot?
Sometimes, but it depends on the space inside the site and on any right-of-way use. Where the lot has no room, the units are placed inside the hoarding line or in permitted right of way, with notice to 311.
Downtown sites often have no lay-down yard and no street frontage to spare. The unit has to fit inside the site fence or in a permitted space in the right of way, and the truck has to reach it without blocking traffic or a sidewalk. A unit that cannot be reached is not provided, so the placement is chosen before the crane and the materials arrive.
Access in older parts of the city is also narrow. Heritage oak canopy over narrow streets can limit the truck's height on the approach, and the route is checked with a tape before the rental starts.
