How many units do I need?
Start with your headcount, not your gut. OSHA 1926.51(c) sets the construction ratio at 1 toilet for 20 workers or fewer, then 1 toilet seat and 1 urinal per 40 workers once you pass 20, and 1 per 50 once you hit 200 or more. Farms and hand-labor crews fall under a different rule: OSHA 1928.110 calls for one facility per 20 employees, reachable within a quarter mile walk, which matters if your Colorado Springs job site stretches across acreage. Events run on a headcount-per-hour formula rather than a fixed roster, so a wedding of 150 needs a different count than a construction crew of 150. Our guide to how many porta potties you need walks through both models in detail. If you are planning a wedding, a festival, or a county fair, size the order to peak attendance, not average attendance, because a lunchtime rush will expose an undersized order fast.
What type of unit fits my job?
Match the unit to the work, not the budget alone. A standard portable toilet covers most construction sites and casual outdoor gatherings, and it runs on a 60 to 70 gallon holding tank sized about 44 by 48 inches on the ground. If guests expect more, a deluxe flushable unit adds a flush mechanism and a nicer interior for weddings or corporate events. For any job open to the public, ADA Standards section 213.2 requires that at least 5 percent of clustered single-user units be accessible, with a minimum of one no matter how small the cluster, so add an ADA accessible unit even for a small block party. Larger crews or multi-day events in Colorado Springs often do better with a restroom trailer, sized as a 2 stall, 4 stall, or 8 stall unit depending on headcount. Renovation crews working with paints, coatings, or solvents should also plan for washing facilities under OSHA 1926.51(f)(1), which applies specifically where paints, coatings, herbicides or insecticides are in use.
Where should the unit go?
Clearance rules do most of the deciding for you. ADA Standards section 403.5.1 requires 36 inches of clear route width to and around any accessible unit, and section 404.2.3 sets the minimum door opening at 32 inches, so measure your path before delivery day, not after. The ground itself matters too: ADA Standards section 302.1 calls for a stable, firm, slip-resistant surface, which rules out soft turf or loose gravel for an accessible placement. If you are renting a roll-off dumpster alongside your restrooms, remember the truck needs about 60 feet of straight clearance behind it to load and unload. Placement in the public right of way in Colorado Springs needs confirming with the city before delivery, so check that before you commit to a curbside spot. Our placement guide and permit requirements page cover the walk-through in more depth, and if you are near a residential septic system, pair your rental plan with a look at septic tank warning signs so you are not solving two problems at once.
When should I schedule service?
Book delivery early and set a service rhythm before the first user shows up. ANSI/PSAI Z4.3, the industry service standard, sets a baseline of one service visit per week for up to 10 users across a 40 hour week, which works for a small job site but falls short fast on a busy event weekend. Multi-week construction jobs in Colorado Springs typically run on monthly rental terms, while a single weekend wedding or festival is priced as a standalone rental. Check the per-day rate page if your job is short and undefined, and the general cost guide if you want the full range side by side.
| unit | day | week | month |
|---|---|---|---|
| standard | $100 - $350 | $130 - $500 | $125 - $325 |
| ada | $200 - $400 | $240 - $400 | - |
| deluxe | $85 - $1200 | $150 - $290 | - |
A standard unit for a single weekend event typically lands between $125 and $400. If your event needs handwashing separate from the toilet itself, note that 29 CFR 1910.141(d)(2) requires soap and towels or a hand dryer at any washing station, since hand sanitizer alone does not satisfy that rule; a handwashing station rental or portable sink rental covers that gap.
Frequently Asked Questions
Do I need a permit for a porta potty in Colorado Springs?
That depends on placement. If the unit sits on private property, most jobs need no separate permit, but placement in the public right of way needs confirming with the city first. Check our permit requirements page before you finalize a curbside or street-adjacent spot.
How far in advance should I book?
Book construction jobs and monthly rentals at least a week out, and weekend events two to three weeks out during peak season. Colorado Springs fills fast on race weekends and festival dates, so early booking protects your preferred delivery window and unit type.
Can I rent just one unit for a small backyard project?
Yes. A single standard unit covers most home renovation jobs and small backyard gatherings. Pair it with a dumpster if you are also clearing debris, since many renovation customers order both together.
What if my event needs an accessible unit?
Order at least one ADA unit regardless of your total headcount. ADA Standards section 213.2 requires it whenever units are clustered, and section 304.3.1 calls for a 60 inch turning circle nearby, so leave that clearance when you plan your layout.
Do storage containers or fencing belong on this checklist too?
If your site needs security or storage alongside restrooms, add them to the same order. A temporary fence rental secures the perimeter, and a storage container rental protects tools and materials between shifts on multi-day Colorado Springs jobs.
