How many units do I need?
Start with headcount, not guesswork. OSHA 1926.51(c) sets construction ratios: 1 toilet for 20 or fewer workers, then 1 toilet seat and 1 urinal per 40 workers once you pass 20, dropping to 1 per 50 at 200 or more. Events run differently. Most planners use one standard unit per 75 to 100 guests for a few hours, scaling up for longer days. If you're not sure which bucket you fall into, this breakdown of unit counts walks through both. For farm and hand-labor crews, OSHA 1928.110 asks for one facility per 20 employees, reachable within a quarter mile walk, which matters if your Indianapolis site spreads across several fields. Always round up, not down. A standard porta potty rental covers most jobs, but check the ADA accessible porta potty requirement below before you finalize the order.
What size and surface does the unit need?
A standard unit runs about 44 by 48 inches on the ground and stands roughly 92 inches tall, so measure your placement spot before delivery day. ADA Standards section 304.3.1 calls for a 60 inch turning circle around accessible units, and section 403.5.1 wants at least 36 inches of clear path leading to them. Ground matters as much as square footage. ADA Standards section 302.1 requires the surface to be stable, firm and slip resistant, which rules out soft mulch or loose gravel for an accessible unit. If you're renting a restroom trailer instead, plan for a level pad and enough clearance for the delivery truck to back in. Our placement guide covers slope, overhead lines and how close units can sit to entrances. Indianapolis job sites with tight lots should also check the dumpster sizes and dimensions page if a roll-off is sharing the same corner.
Do I need a permit for placement?
Maybe. Placement in the public right of way, on a sidewalk, or in a street lane usually needs sign-off, and that has to be confirmed directly with the City of Indianapolis before delivery. We can't quote a rule number here because it varies by exact location and by whether the unit sits on private property or public frontage. Start with our permit requirements page for the questions to ask, and loop in your contractor if this is a construction site services job where the general contractor holds the permit. Renting for a private event on your own property is usually simpler, but if you're near a street, a park, or a venue with its own rules, ask before delivery day, not after the truck is already circling the block looking for a driveway.
What does a rental include and cost?
Pricing depends on unit type and rental length, and longer terms cost more in total but less per day. Here's what typical Indianapolis rentals run:
| Unit | Day | Week | Month |
|---|---|---|---|
| Standard | $100-$350 | $130-$500 | $125-$325 |
| ADA accessible | $200-$400 | $240-$400 | -- |
| Deluxe flushable | $85-$1200 | $150-$290 | -- |
Delivery fees typically add $100 to $150 for a single day and $50 to $150 for a week, separate from the unit rate. Weekend rentals for a standard unit generally land in the $125 to $400 range, priced as a flat block rather than a daily multiple. For a deeper breakdown by rental length, see porta potty rental cost, porta potty rental per day, and monthly porta potty rental. Servicing follows the ANSI/PSAI Z4.3 baseline of one visit per week for up to 10 users across a 40 hour week, though busy sites often need more frequent stops, which our cleaning schedule page explains. If you need a handwashing station rental alongside the toilets, 29 CFR 1910.141(d)(2) requires soap and towels or a hand-drying device at that station, since sanitizer alone doesn't satisfy the rule.
Water access matters too. OSHA 1926.51(a)(1) requires an adequate supply of potable water at any place of employment, which is why most construction accounts pair toilets with a handwash unit rather than relying on sanitizer gel. If your crew handles paint, coatings, herbicides or insecticides, OSHA 1926.51(f)(1) requires washing facilities specifically for that contaminant exposure, not just a general sink. Check our handwashing requirements page if that applies to your Indianapolis site.
Last item on the list: confirm delivery access. A roll-off truck needs about 60 feet of straight clearance behind it, and portable restroom trucks need something close to that for a clean setup. If you're coordinating multiple services, our service areas page lists coverage out to towns like Greenwood, 15.4 miles south, and Fishers, 17.4 miles northeast, so you can plan delivery windows around drive time.
How far in advance should I book?
Book standard units at least a week out for events, longer for construction accounts needing weekly service. Peak weekends in Indianapolis fill fast, especially near festivals. If your date is inside 72 hours, check emergency porta potty rental for faster turnaround options.
Do I need an ADA unit even for a small event?
If you're clustering multiple single-user units, ADA Standards section 213.2 requires at least 5 percent to be accessible, and never fewer than one. Even a two-unit setup needs one accessible unit under that rule.
Can I place a unit on grass or gravel?
Grass works if it's firm and level. Loose gravel or soft mulch fails the slip-resistant surface standard under ADA 302.1 for accessible units. Ask about a plywood pad if your Indianapolis site has soft ground.
What happens if I underestimate headcount?
Lines form, units fill faster, and service visits may need to increase mid-rental. It's cheaper to add one extra standard unit upfront than to call for a same-day swap once guests or crew arrive.
Does a construction site need more than one unit type?
Often yes. Crews frequently pair a standard porta potty rental for daily use with a storage container rental or temporary fence rental for site security, especially on multi-week Indianapolis builds.
