Job sites follow OSHA. OSHA 29 CFR 1926.51 requires 1 unit for up to 20 workers, then 1 toilet seat and 1 urinal per 40 workers from 20 to 199 workers, and 1 per 50 workers at 200 or more. Hand washing has to be available where the work involves contaminants.
Job sites are counted by peak crew, not by project headcount. A Cambridge site running 60 workers during framing and 12 during fit out needs provision sized for 60 while that phase lasts.
Review the schedule when the site changes. A Cambridge project that needed twice weekly during framing rarely needs it through a fit out with a third of the crew.
What should you plan for in Cambridge?
On public facing Cambridge events, put at least one ADA accessible unit on a level, firm route from the main area. Accessible does not help if the path to it is gravel or grass.
The access rule is simple and worth designing around: within about 25 feet of where the truck can stop. Courtyards and rear lots on Cambridge sites frequently fail it.
Order enough standard units and the ADA unit stays available for the people who need it. Accessible units get used by everyone when the queue at the standard units is long, which is a capacity problem rather than a signage one.
Units arrive from the yard cleaned, restocked and deodorised, so the first use is on a fresh unit. On a Cambridge event that is the detail guests actually notice.

Cambridge porta potty questions
How many units do I need for 150 guests?
Start at 3 standard units for a 4 hour event. Add roughly 15 percent if alcohol is served, include at least one ADA unit, and add one hand wash station.
Do restroom trailers need power and water?
Most do. Trailers typically need a standard power connection and either a water hookup or an onboard fresh water tank, and they need level ground to sit on.
What happens if a unit is not serviced on schedule?
Call the provider. If the truck could not reach the unit, the visit normally still counts as billed, so keeping the approach clear on service days matters.
Do units need lighting at a Cambridge event?
For anything running past dusk, yes. Most units have a daylight roof panel only and become unusable after dark without surrounding light.
How much notice do you need for a Cambridge job site?
A few days is usually enough for a standard unit. Trailers, ADA units and large multi unit orders need longer, particularly in peak season.
