How many units do you actually need?
Start with headcount and hours, not guesswork. OSHA 1926.51(c) sets construction crew ratios: 1 toilet for 20 workers or fewer, then 1 toilet seat and 1 urinal per 40 workers once you pass 20, and per 50 once you hit 200 or more. For events, the math runs differently and our sizing guide walks through both. Farm crews fall under a separate rule: OSHA 1928.110 calls for one facility per 20 hand-labor employees, reachable within a quarter mile, which matters for agricultural jobs spread across a field. Construction sites juggling trailers, trash and fencing all at once should look at full site services rather than ordering pieces separately. If your event runs a single weekend, standard unit counts differ from a month-long construction dumpster rental job, so match your count to duration, not just headcount.
What size unit fits the job?
A standard unit runs about 44 by 48 inches on the ground and stands roughly 92 inches tall, with a 60 to 70 gallon holding tank underneath. That footprint works for most portable toilet rental jobs in Brownsville, but bigger crews or upscale events need more. A deluxe flushable porta potty adds a flush mechanism and sink for weddings or corporate sites. For guests who need more room, ADA Standards section 304.3.1 requires a 60 inch turning circle, and section 404.2.3 sets a 32 inch minimum clear door opening; our ADA accessible porta potty meets both. Larger crowds outgrow single stalls fast, and a 2 stall restroom trailer or 4 stall restroom trailer handles the overflow better than adding five more standalone units scattered across a Brownsville lot.
Do I need an ADA-accessible unit?
Yes, once you cluster units. ADA Standards section 213.2 requires at least 5 percent of clustered single-user portable toilets to be accessible, and never fewer than one, no matter how small the job. The accessible unit also needs a 36 inch clear path in, per ADA Standards section 403.5.1, and stable, slip-resistant ground under it per section 302.1. Check our ADA restroom requirements page before locking in your order. This isn't optional for public events in Brownsville: a wedding at a rented hall, a county fair booth, or a marathon route all count as clustered placements. Pair it with a broader portable restroom rental plan so the accessible unit sits in the same line of sight as the rest, not tucked behind a fence where nobody can find it.
Where should the units go?
Placement decides whether delivery goes smoothly or turns into a headache. A roll-off delivery truck needs about 60 feet of straight clearance behind it, and porta potty trucks need similar room to back in and level the unit. Check overhead lines, soft ground and slope before the truck shows up; our porta potty placement guide covers grading and clearance in more detail. If you're near Cameron Park, 6.6 miles southwest of Brownsville, or Los Fresnos, 8.1 miles northwest, confirm the delivery address is accessible by a full-size truck, not just a passenger car. Placement in the public right of way needs confirming with the city directly, since Brownsville's specific rule on that isn't something we can quote here; check with the city before you set units at a curb or sidewalk edge. See porta potty permit requirements for what to ask about.
Service and cleaning schedule
ANSI/PSAI Z4.3 sets a baseline of one service visit per week for up to 10 users across a 40 hour week; busier sites need more frequent pumping. Handwashing matters too: 29 CFR 1910.141(d)2) calls for soap and towels or a hand-drying device, not sanitizer alone, so pair your order with a handwashing station rental or portable sink rental. If your crew works with paints, coatings or pesticides, OSHA 1926.51(f)(1) requires washing facilities specifically for that exposure. Review our how often are porta potties cleaned page for what a normal visit includes. Standard unit rentals run from single days to full months; check porta potty rental cost or monthly porta potty rental for the pricing spread by duration.
| Duration | Low | Typical | High |
|---|---|---|---|
| Day | $100 | $150 | $350 |
| Week | $130 | $200 | $500 |
| Month | $125 | $200 | $325 |
How far in advance should I book?
Book as early as you can once you know your date, especially for weekend events or peak construction season. Units, trucks and drivers get scheduled days out, and last-minute calls limit your options. For urgent situations, see emergency porta potty rental.
What if my event runs on a weekend only?
Weekend rentals cost more per day than week-long bookings, since the unit still needs full delivery and pickup for a short window. A standard unit weekend rate typically runs $125 to $400. Ask about event restroom rental packages built for two-day events.
Can I add handwashing stations to my order?
Yes, and most Brownsville sites should. A grease trap or contaminant-heavy job triggers OSHA 1926.51(f)(1) directly. Bundle a hand sanitizer station rental or full sink unit with your toilet order; see handwashing requirements for the full breakdown.
Do I need a permit for a porta potty in Brownsville?
Right-of-way placement needs confirming with the city; we can't quote a specific ordinance here. Driveway or private lot placement usually avoids that question entirely. Check porta potty permit requirements before you finalize a curbside spot.
What's the difference between a porta potty and a restroom trailer?
A standard unit is a single stall with a holding tank; a trailer has multiple stalls, sinks and often flush plumbing. Trailers suit weddings and multi-day events better. Compare options at restroom trailer rental or check restroom trailer rental cost for pricing.
