How many porta potties does a job site need?
A job site needs 1 porta potty for up to 20 workers, then 1 seat and 1 urinal for every 40 workers, under OSHA 29 CFR 1926.51 Table D-1. Once a site reaches 200 workers, the ratio becomes 1 seat and 1 urinal per 50. Each standard unit we rent has both, so it counts as one full set.
| Crew size | OSHA floor (29 CFR 1926.51, Table D-1) | Worked example |
|---|---|---|
| 1–20 workers | 1 toilet | A 5-person framing crew in Killeen: 1 unit |
| 21–199 workers | 1 seat plus 1 urinal for every 40 workers | 120 workers ÷ 40 = 3 units |
| 200 or more | 1 seat plus 1 urinal for every 50 workers | 230 workers ÷ 50 = 4.6, so 5 units |
The rule versus what works. OSHA sets the minimum. We plan about 1 unit per 10 workers on a 40-hour week with one weekly cleaning, because a 60-gallon tank fills faster than the rule expects.
Crews working 50-hour weeks, or any crew in July heat, should add a second weekly visit. Read the rule at 29 CFR 1926.51 on eCFR, or run your crew size on the calculator's crew tab.
Do construction sites need a hand wash station?
Construction sites need washing facilities under OSHA 29 CFR 1926.51(f) whenever workers apply paint, coatings, herbicides or pesticides, or handle other harmful materials. The rule calls for running or tepid water, soap and towels. For everyday framing and roofing crews, a station is optional but cuts down on sick days.
Our two-sink station holds 22 gallons, about 350 washes, and we refill it each week. See hand wash station specs, and read the full OSHA toilet rules for Central Texas job sites.
Can you deliver to job sites on Fort Hood?
Yes. Commercial trucks enter Fort Hood through the North Clarke Road truck inspection gate off westbound I-14/US-190, and every person in the truck is checked against FBI databases. Give us the contracting officer or site contact and the building number, and book on-post deliveries at least a day ahead.

Where should a job site porta potty go?
Put a job site porta potty on level ground within about 100 feet of where our service truck can stop, clear of trenches, crane swing areas and material drops. Turn the door away from the street. On sloped lots west of Killeen and in Copperas Cove, pick the flattest pad near the site entrance.
| What our crew needs | Standard or flushing unit | Wheelchair-accessible unit | Restroom trailer |
|---|---|---|---|
| Clear width through gates or paths | At least 4 ft (units are 43.5–47 in wide) | About 5.5 ft (unit is 62 in wide) | A drive about 10 ft wide to the spot |
| Headroom | 8 ft (units stand 91 in) | 8 ft | 12 ft for the trailer and roof A/C |
| Ground | Flat and firm: slab, gravel, caliche, packed soil or turf | Flat, firm and on a route a wheelchair can use | Close to level; we shim with blocks |
| Hose reach for service | Within about 100 ft of where the truck parks | Within about 100 ft | Truck backs right up to it |
| Hookups | None | None | 20-amp, 110-volt outlet within 50 ft, or a generator |
A few cities we serve spell out job site toilets. Cedar Park's residential guidelines say a "Port-o-can must be provided, to services area of no more than four houses," checked at the building layout inspection (Cedar Park residential guideline packet). See our Cedar Park page.

How are construction rentals billed?

Construction Site Toilets: common questions
Can you deliver to a lot with no street address yet?
Yes. Send a map pin, cross streets or the lot and block number, plus a site contact's phone.
Can I rent a unit for a 3-day roofing job?
Yes, as a short-term rental. Same-day delivery is available, but ordering a day ahead skips the same-day fee.
Do you take purchase orders?
Yes, for commercial accounts. Ask about monthly statements and net terms.
Can the unit move as the job moves?
Yes. We relocate units on site for a per-move fee, and towable units suit road crews.
What if a unit tips over or gets damaged?
Call right away. We clean up and swap the unit. Damage from misuse or vandalism is billed under our rental terms.
