How many units do you actually need?
Start with headcount, not guesswork. OSHA 1926.51(c) sets construction sites at 1 toilet facility for 20 workers or fewer, then 1 toilet seat and 1 urinal per 40 workers once you pass that mark, scaling to one per 50 at 200 or more. Farms and agricultural crews fall under a different rule: OSHA 1928.110 calls for one facility per 20 hand-labor employees, reachable within a quarter mile walk. Events run on a different math entirely, driven by guest count and hours, not labor law. If you are still not sure where your job lands, our guide on how many porta potties you need walks through both formulas. Weddings and festivals usually want a mix: a few standard units, one deluxe flushable unit near the tent, and an ADA accessible unit by the entrance. ADA Standards 213.2 requires at least 5 percent of a cluster to be accessible, never fewer than one unit, so a bank of ten needs at least one ADA-compliant stall.
Where should units go on site?
Pick flat, stable ground with truck access before you pick a spot near the action. Our delivery trucks need about 60 feet of straight clearance behind the unit to place it safely, so a tight alley in downtown Norfolk or a fenced lot off Hampton Boulevard needs a walkthrough first. Surfaces should be firm and slip resistant under ADA Standards 302.1, which matters most after rain rolls in off the harbor. Keep a 36 inch clear path to every unit per ADA Standards 403.5.1, and if you are renting an ADA unit, the door opening itself needs 32 inches clear under ADA Standards 404.2.3. Ramps built to reach a unit cannot run steeper than 1:12 per ADA Standards 405.2. If your event sits near temporary fencing or a crowd barrier line, leave a service lane so the pump truck can reach every unit on cleaning day without rerouting foot traffic.
When should you book before the event?
Book as soon as your date and headcount are locked, ideally two to three weeks out for anything over a hundred guests. Standard units run $100 to $350 a day, with weekly rentals landing between $130 and $500 depending on unit count and add-ons. Weekend events in Norfolk typically run $125 to $400 for the rental itself, plus a delivery fee that ranges $50 to $150 for weekly jobs or spikes to $125-$540 for weekend turnarounds. Monthly job sites pay $125 to $325 for the unit alone. Longer construction jobs should check monthly porta potty rental rates before committing to weekly billing, since the per-day cost drops the longer the unit stays. If you are still pricing options, the full cost breakdown covers every duration side by side.
| unit | day | week | month |
|---|---|---|---|
| standard | $100-$350 | $130-$500 | $125-$325 |
| ADA | $200-$400 | $240-$500 | - |
| deluxe | $85-$1200 | $150-$290 | - |
What service schedule keeps units usable?
Weekly service is the baseline, and ANSI/PSAI Z4.3 sets one visit per week for up to 10 users across a 40 hour week as the standard interval. High-traffic weekend events need more frequent pumping, especially with 200-plus guests cycling through a handful of units. Every unit on our routes carries a 60 to 70 gallon holding tank, and a standard unit measures roughly 44 by 48 inches on the ground and stands about 92 inches tall, so plan clearance accordingly when units sit near handwashing stations or a portable sink setup. Handwashing itself has two separate rules worth knowing: general sanitation falls under OSHA 1926.51(c), while washing facilities tied specifically to paints, coatings, herbicides or insecticides trigger OSHA 1926.51(f)(1). Either way, 29 CFR 1910.141(d)(2) requires soap and a towel or hand-drying device at any wash station; hand sanitizer alone does not satisfy that rule. Crews working near Chesapeake, 23.0 miles south of Norfolk, or out toward Hampton, 12.6 miles north, follow the same schedule since routes run daily across both.
What's the difference between a standard unit and a deluxe unit?
A standard unit is a basic non-flushing toilet with hand sanitizer built in. A deluxe flushable unit adds a flush mechanism, a sink, and interior lighting, and it costs more per day, roughly $85 to $1200 depending on features and rental length.
Do I need an ADA unit even for a small event?
If you are clustering multiple single-user units, yes. ADA Standards 213.2 requires at least one accessible unit in any cluster, regardless of how small the cluster is, with no exception below 5 percent.
How far in advance should I book for a Norfolk wedding?
Two to three weeks out is safe for most venues. Peak season weekends book faster, and deluxe or restroom trailer units move first, so lock your date before finalizing headcount if you are close to a holiday weekend.
Can I rent a single unit for a one-day home project?
Yes. Day rentals for a standard unit run $100 to $350, and home renovation projects typically need only one unit unless the crew tops 20 workers under OSHA thresholds.
What happens if my event runs longer than planned?
Call ahead and we extend service before your scheduled pickup. Rates scale by duration already built into weekly and monthly pricing, so extending a day rental into a week costs less per day than paying repeated daily rates, and it avoids a rushed emergency porta potty call.
