Book units at least 1 per 20 workers under OSHA 1926.51(c), confirm delivery clearance, pick a unit type, and lock a service day before the truck shows up. Skipping any of the four is the most common reason a Commerce City job site or event ends up short on the day it matters most.
Start with headcount, not guesswork. OSHA 1926.51(c) sets 1 toilet for 20 workers or fewer, then 1 toilet and 1 urinal per 40 workers once you pass 20, scaling to 1 per 50 once a crew hits 200. Agricultural crews fall under a different rule: OSHA 1928.110 calls for a facility within a quarter mile walk, one per 20 hand-labor workers. Events run on guest count and hours, not labor law, so a wedding or festival planner should work from our porta potty placement guide instead. If your Commerce City crew is small and mixed with subcontractors, round up. Our how many porta potties do I need page walks the math in more detail, and if you are staging an event rather than a build, check event restroom rental for guest-per-unit ratios instead of the OSHA table.
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. That footprint matters when you're squeezing a unit next to a fence line or a trailer on a tight Commerce City lot. Long-haul crews often step up to a deluxe flushable porta potty for better hand comfort over a multi-week job. Any site expecting visitors with mobility needs should plan for ADA accessible porta potty units: ADA Standards 213.2 requires at least 5 percent of clustered single-user units be accessible, never fewer than one, with a 60 inch turning circle under 304.3.1 and a 32 inch clear door opening under 404.2.3. Larger crews or multi-day events sometimes skip individual units entirely and go with a 2 stall restroom trailer or 4 stall restroom trailer instead, which also solves handwashing in one footprint.
Placement decides half your headaches before the truck ever leaves the yard. The route to each unit needs a stable, slip-resistant surface under ADA 302.1, and a minimum 36 inch clear path under ADA 403.5.1 if the site expects public or mixed-ability foot traffic. A roll-off delivery on the same site needs about 60 feet of straight clearance behind the truck, so if you're pairing a roll-off dumpster rental with your restroom order, walk both drop zones before the trucks arrive. Keep units clear of active work per the housekeeping standard in OSHA 1926.25, and if the job involves any barricading near excavation or traffic, review temporary fence rental or a crowd control barrier rental alongside your restroom layout. Confirm ahead of time whether placement in the public right of way needs sign-off from the City of Commerce City; that is not something to guess at on delivery day.
Book delivery at least a few days ahead for standard jobs, and treat anything inside 24 hours as emergency porta potty rental territory. ANSI/PSAI Z4.3 sets a baseline service interval of once a week for up to 10 users across a 40 hour week, so a 20-person crew running two shifts needs to service more often, not less. Washing facilities tied specifically to paints, coatings, herbicides or insecticides fall under OSHA 1926.51(f)(1), while general handwashing setup should still meet 29 CFR 1910.141(d)(2), which requires soap and towels or a hand-drying device; hand sanitizer alone does not satisfy it. Pair your restroom order with a handwashing station rental rather than relying on sanitizer stations alone for a construction crew. For pricing across timeframes, compare a porta potty rental per day quote against a monthly porta potty rental before you commit, since Commerce City Porta Pros prices differently by duration.
| unit | day | week | month |
|---|---|---|---|
| standard | $100 - $350 | $130 - $500 | $125 - $325 |
| ada | $200 - $400 | $240 - $400 | - |
| deluxe | $85 - $1,200 | $150 - $290 | - |
A standard unit over a weekend typically runs $125 to $400, which matters if your event falls Friday through Sunday rather than a full week. See porta potty rental cost for the full breakdown by unit and duration before you request a quote.
Commerce City sites near Brighton, roughly 9.5 miles north, or Derby, about 9.0 miles southwest, should factor drive time into delivery windows, especially for early-morning construction starts. If your project sits closer to Northglenn, 12.5 miles west, confirm your delivery window when you request a quote rather than assuming a standard slot.
Book standard jobs several days out and treat same-day needs as emergency service. Event season fills fast, so weddings and festivals should lock units weeks ahead. Construction crews starting a multi-month job should set a recurring service day immediately rather than scheduling call-by-call.
Yes, if the public attends. ADA Standards 213.2 requires at least one accessible unit whenever single-user toilets are clustered, regardless of total headcount. A 20-guest backyard event with no public invitation is different from a ticketed festival open to anyone.
Units run out of capacity faster than expected and service intervals get overwhelmed. OSHA 1926.51(c) ratios are a floor, not a comfort number. Rounding up one unit per tier, especially past 40 or 100 workers, avoids a mid-week emergency call.
That needs confirming with the City of Commerce City before delivery. Placement rules vary by lot, road type and event permit status, and nothing here should be treated as a blanket yes. Ask your provider to confirm before the truck is dispatched.
Not automatically. Many standard units ship without a sink, so pair the order with a handwashing station if your crew or guests need soap-and-water access under 29 CFR 1910.141(d)(2). Deluxe and trailer units often include a built-in sink instead.
