At least 5 percent of a cluster of portable toilets must be ADA accessible, and never fewer than one unit, per ADA Standards section 213.2. For a Woodland event or job site with 20 standard units, that means a minimum of one wheelchair-accessible unit, sized for an actual turning circle inside.
An ADA accessible porta potty is not just a bigger box. ADA Standards section 304.3.1 calls for a 60 inch diameter turning circle inside the unit, enough room for a wheelchair to rotate fully. The door opening has to clear 32 inches per section 404.2.3, and the path leading up to it needs a minimum 36 inch clear width under section 403.5.1. Woodland job sites and event grounds both have to account for that approach path, not just the unit itself. Floors and ground surfaces under the unit must be stable, firm and slip resistant per section 302.1, which usually means a level pad, not gravel or soft turf. Grab bars, a lower toilet seat height, and door hardware that operates with one hand and under 5 pounds of force, per section 309.4, round out the build. If you are placing units for a wedding, a fair, or a construction crew, our porta potty placement guide walks through the ground prep these units actually need.
The 5 percent rule from ADA Standards 213.2 is the floor, not a suggestion, and it applies whether you are renting from Woodland Porta Pros for a backyard project or a full festival footprint. One accessible unit is required no matter how small the cluster gets. Construction sites layer a second rule on top: OSHA 1926.51(c)(1) sets toilet counts by crew size, one facility for 20 workers or fewer, scaling up from there. Neither rule waives the other. If you are unsure how many total units your headcount calls for before applying the accessible percentage, the how many porta potties do I need guide breaks down the math by worker or guest count. For events specifically, our event restroom rental page covers guest-count ratios that differ from a job site crew.
Reach range matters as much as unit count. ADA Standards section 308.2.1 caps a forward reach at 48 inches high and 15 inches low, which is why grab bars and paper dispensers inside an accessible unit sit lower than you would expect. If a ramp is needed to reach the unit, section 405.2 limits the running slope to 1:12, so a unit set on a raised pad or curb in downtown Woodland needs a longer ramp run than most people plan for. Placement also has to account for delivery access: a standard porta potty rental unit needs a stable, mostly flat spot, and our crews figure that into every drop in Woodland and out toward Yolo, about 7.2 miles northwest, or Monument Hills, roughly 8.3 miles west. If your site has a loading dock or narrow lot, mention it when you request a quote so we route the right truck.
Short answer: almost always yes, once you have any portable toilets at all. The 213.2 clustering rule triggers as soon as you have more than one unit on site, and OSHA's general sanitation rule at 1926.51(c) governs construction crews regardless of accessibility questions. Field crews working agricultural sites fall under a separate standard, OSHA 1928.110, which requires potable water, toilets and handwashing within a quarter mile walk of hand-labor employees, at one facility per 20 workers. That standard shows up often on farm work outside Woodland proper, and our farm and agricultural restrooms page covers it in more depth. Whether you are booking a deluxe flushable porta potty for a wedding or a fleet of standard units for a subdivision build, the accessible unit requirement rides along automatically. Renting through a construction site services package does not exempt you from it either.
| unit | day | week | month |
|---|---|---|---|
| standard | $100 to $350 | $130 to $500 | $125 to $325 |
| ada | $200 to $400 | $240 to $240 | not commonly quoted |
ADA units carry a premium across the board; even weekly ADA rates in Woodland run at or above the low end of the day rate. Full breakdowns live on our porta potty rental cost and porta potty rental per day pages, and long-term jobs should check monthly porta potty rental for better per-day math.
Only clusters of more than one unit trigger the requirement under ADA Standards 213.2, but that threshold is low. A single unit at a small backyard job has no accessible mandate. Two or more units, even at a small Woodland job site, means at least one has to be accessible.
Yes. Some Woodland renters book a single ADA unit for a small event with an anticipated guest needing accessible access. It works like any porta john rental booking, just built to the wider dimensions and grab bar spec.
A standard unit runs about 44 by 48 inches on the ground and stands roughly 92 inches tall. ADA units are built wider inside to fit the 60 inch turning circle required by section 304.3.1, so the footprint is noticeably larger.
Yes, when trailers serve as the primary restroom option. Our restroom trailer rental and ADA restroom requirements pages both apply the same door width and reach-range standards; check the 4 stall restroom trailer page for accessible stall configurations.
ADA Standards are federal, so enforcement runs through civil rights complaint channels rather than a Woodland department. Confirm any placement questions tied to public right of way with the city directly before your event date.
