How many units do I actually need?
Start with your headcount, not your gut. OSHA 1926.51(c) sets the construction ratio: one toilet for 20 workers or fewer, then one toilet seat and one urinal per 40 workers once you pass 20, dropping to one seat and one urinal per 50 at 200 or more. For events, our placement guide and the how many porta potties do I need page walk through headcount math in more detail. If you are running a farm crew, field sanitation falls under OSHA 1928.110 instead, which asks for one facility per 20 hand-labor employees within a quarter mile walk. Renovation jobs around Renton usually need just one standard unit, while a multi-crew build might call for several plus a dedicated ADA accessible porta potty. Check the OSHA portable toilet requirements page before you finalize a count, and if the job runs long, look at monthly porta potty rental pricing instead of booking week to week.
What does the unit itself need to clear?
A standard unit is about 44 by 48 inches on the ground and stands roughly 92 inches tall, so measure your spot before delivery day, not after the truck shows up. If anyone on-site uses a wheelchair, ADA Standards section 213.2 requires at least 5 percent of clustered units to be accessible, with a minimum of one no matter how small the cluster. That accessible unit needs a 60 inch turning circle under section 304.3.1 and a 32 inch clear door opening under section 404.2.3, plus a 36 inch clear path per section 403.5.1. Ground surface matters too. ADA section 302.1 calls for stable, firm, slip-resistant footing, which rules out loose gravel or soft turf as a pad. Ramps, if you need one, cannot exceed a 1:12 slope per section 405.2. Review the full ADA restroom requirements page and compare a deluxe flushable porta potty against a standard unit if your crew or guests will be on-site more than a few hours.
Where should the unit actually go?
Pick level, stable ground within reach of a service truck, and keep it away from soft soil that turns to mud in Renton's wetter months. Delivery crews need roughly 60 feet of straight clearance behind the truck to maneuver, so a driveway, a lot corner, or a curb lane with a clear approach all work better than a tight courtyard. Keep the unit at least a short walk from food service or prep areas, and never block a fire lane or an accessible route. If you are placing units in the public right of way anywhere in Renton, that placement needs confirming with the city directly, since we cannot state a permit rule without checking it first. For construction sites, pair placement with the temporary fence rental or chain link temporary fence layout so the toilet sits inside the secured perimeter, not outside it. Lighting matters after dark too. OSHA 1926.56(a) sets minimum illumination levels for active construction areas, so a nearby light tower rental may be worth adding to the checklist for evening shifts.
Should I add handwashing or is the unit enough?
Add a separate handwashing station if your crew works with paint, coatings, herbicides, insecticides, or anything else that counts as a harmful contaminant under OSHA 1926.51(f)(1); that standard exists specifically for those exposures, not for general hand hygiene. For everyday sanitation, 29 CFR 1910.141(d)(2) still applies at general industry sites and requires soap plus towels or a hand-drying device, not sanitizer alone. A handwashing station rental or portable sink rental covers that gap fast, and a hand sanitizer station rental is a fine add-on but never a substitute where the regulation calls for real washing. Review the handwashing requirements page before your crew starts work, especially on paint or coating jobs. Service interval matters here too: ANSI/PSAI Z4.3 sets a baseline of one service visit per week for up to 10 users over a 40 hour week, so a bigger Renton crew or a busy event weekend needs more frequent pumping, not the standard schedule. Add that to your porta potty rental cost planning early, since service frequency changes the porta potty rental per day math.
| unit | day | week | month |
|---|---|---|---|
| standard | $100-$350 | $130-$500 | $125-$325 |
| ada | $200-$400 | $240-$400 | n/a |
| deluxe | $85-$1200 | $150-$290 | n/a |
Weekend rates run separately from these day, week and month figures; a standard unit weekend typically falls between $125 and $400 depending on count and add-ons. If your job runs long, renting the standard unit for a month usually beats paying week to week.
Frequently asked questions
How far out should I book before an event?
Book at least a week out for anything over 50 guests, longer during Renton's busy event season. Renton Porta Pros can sometimes turn around faster, but locking dates early protects your unit count and avoids a scramble. Check emergency porta potty rental if something falls through last minute.
Do I need a permit to place a unit in Renton?
Right-of-way placement needs confirming directly with the city; we are not stating a specific rule here. On private property you generally have more flexibility. See the porta potty permit requirements page for what to ask when you call.
What is the difference between a standard and deluxe unit?
A standard unit is a basic non-flushing toilet with a 60 to 70 gallon holding tank. A deluxe flushable porta potty adds a flush mechanism and often a sink, at a higher price point shown in the table above.
Can one unit serve a whole small crew?
Under OSHA 1926.51(c), one toilet covers up to 20 workers, so a small Renton crew often needs just one standard unit. Once you pass 20 workers, add a second facility to stay compliant.
Does Renton Porta Pros serve nearby cities too?
Yes. Renton Porta Pros delivers to Tukwila, 6.3 miles west, and SeaTac, 8.0 miles southwest, along with other nearby areas listed on the service areas page.
