Porta Potty Requirements by Crew Size (OSHA Chart + Real-World Planning)
Use this page to answer, fast: “How many portable toilets do I need?” We include OSHA minimums, plus the planning guidance that prevents long lines, odor, and downtime. Pottys Plus delivers across NJ—including Jersey City, Newark, and Bayonne—and services sites along the NJ Turnpike (I-95), I-78, I-280, and Route 440.
OSHA construction sanitation minimums come from 29 CFR 1926.51(c)(1) Table D-1. These are baseline requirements; heavy-use sites often need more.
| Crew Size (on site) | OSHA Minimum (Construction) | Best-Practice Planning (To prevent downtime) |
|---|---|---|
| 1–20 | 1 toilet | 1 toilet per 10–15 workers if heavy use, heat, long shifts, or no nearby indoor restroom. |
| 21–40 | At least 1 toilet seat + 1 urinal (Table D-1 scales per 40 workers) | Consider 2 toilets (or 1 + urinal) if multiple trades or peak break times. |
| 41–80 | 2 toilet seats + 2 urinals | Add units or increase pumping if you see lines, odor by mid-day, or high paper usage. |
| 81–120 | 3 toilet seats + 3 urinals | Plan separate banks by work zone (reduces walking time and “nobody uses it” problems). |
| 121–200 | 1 toilet seat + 1 urinal per 40 workers | Often needs more than minimum if hot weather, concrete pours, or long shifts. |
| 201+ | 1 toilet seat + 1 urinal per 50 workers | Add redundancy (spare unit) and increase service frequency to avoid shutdown risk. |
OSHA Minimum vs “Won’t Get Complaints” Planning
OSHA minimums are a baseline. In the real world, restroom performance depends on: shift length, heat, number of trades, lunch/break timing, and whether workers have quick access (not a 6-minute walk).
Option A: Publish OSHA minimum (compliance-first)
- Use the table above as your baseline for OSHA compliant construction restrooms.
- Pair it with a documented weekly porta potty service plan.
Option B: Publish best-practice planning (operations-first)
- For active jobsites, plan closer to 1 toilet per 10–15 workers if heavy use or no indoor restroom.
- Hot weather + direct sun → add service frequency or add units.
- Multiple floors/zones → place units by work area to reduce downtime.
When you need separate women’s units
If your units are multi-stall or not single-occupancy, you’ll typically need separate facilities for each sex. Many portable restrooms are single-occupancy, which simplifies compliance and usage.
Delivery & Placement Reality (NJ)
For reliable delivery and service, access matters. If you want to avoid redelivery risk, run our access tool: Delivery Access Checker.
- Gate & route: confirm access is clear and reachable from the street.
- Plan for service: placement should allow safe servicing during the project.
- Spill prevention: use trays on sensitive surfaces—see containment trays.
New Jersey Jobsite Scenarios (Real Planning Examples)
These examples reflect common projects across North Jersey—from logistics corridors near the Turnpike to urban sites around Jersey City, Newark, and Bayonne.
Construction (Urban / Tight Access)
Crew: 35 • Duration: 8 weeks
Suggest: 2–3 units + 2x per week service (increase in heat).
Best for sites near I-78 / I-280 corridors where break spikes happen.
Warehouse / Logistics
Crew: 75 • Multi-trade • Long shifts
Suggest: add units by zone + increase pumping vs one “overloaded” bank.
Common along NJ Turnpike (I-95) and Route 440 routes.
Public / Municipal Work
Crew: 20 • Roadwork / parks
Suggest: 1–2 units + placement that supports safe servicing.
Pair with handwash station rentals for public-facing sites.

FAQs (Voice-Search Friendly)
What are the OSHA restroom requirements for construction crews?
OSHA’s construction sanitation minimum comes from 29 CFR 1926.51(c)(1) Table D-1: 20 or fewer workers need 1 toilet; above that, toilets/urinals scale by headcount. [oai_citation:1‡OSHA](https://www.osha.gov/laws-regs/interlinking/standards/1926.51/all?utm_source=chatgpt.com)
Is it really one porta potty per 10 workers?
That’s a common planning rule for comfort and productivity—especially for heavy use, long shifts, and hot weather. The OSHA construction minimum is different (Table D-1). Many sites choose 1 per 10–15 to prevent lines and complaints.
How often should porta potties be serviced on a jobsite?
It depends on crew size, heat, and usage. A common baseline is weekly service, but medium/heavy use often needs 2x per week or more. Use our estimator: Service Frequency Estimator.
Do I need an ADA portable restroom on a construction site?
Many public-facing sites and certain project requirements call for an ADA-compliant unit. We recommend including an ADA option when the job is open to the public or when accessibility is required by the project. See: ADA unit details.
What’s the fastest way to get an accurate recommendation?
Text your address, crew size, duration, and start date to 732-592-1800. We’ll recommend unit count + a service plan that prevents overflow calls and downtime.
