What makes a porta potty ADA compliant?
Size and reach, mostly. 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 has to open at least 32 inches wide under section 404.2.3, and inside, the floor has to be stable, firm and slip resistant per section 302.1, so no loose gravel pad or soft ground under the unit. Grab bars and the toilet paper holder need to sit within reach ranges set by section 308.2.1, a 48 inch maximum and 15 inch minimum, and any latch or flush handle has to work with one hand and no more than 5 pounds of force under section 309.4. Standard units run about 44 by 48 inches on the ground and stand roughly 92 inches tall, which is why an ADA accessible porta potty is built on a wider footprint than a standard porta potty rental. If your Savannah event or crew needs one unit or twenty, the accessible ones cannot be an afterthought bolted on at the end.
How many ADA units do I need?
At least one, and the math scales from there. ADA Standards section 213.2 says that where single-user portable units are clustered, a minimum of 5 percent must be accessible, and never fewer than one. So ten standard units on a site means at least one ADA unit alongside them, and larger events in Savannah scale the same way. This is separate from the OSHA worker-count math under OSHA portable toilet requirements, which sets ratios by headcount rather than accessibility. Use our how many porta potties do I need guide to work out your base count first, then apply the 5 percent rule on top. Event planners running a festival restroom rental or a wedding restroom rental in Savannah often round up rather than down, since running short on accessible units mid-event is not something you can fix by delivery truck same day. A marathon and race restrooms layout usually spreads ADA units at intervals along the course rather than clustering them all at the start line.
Where do ADA units need to go on site?
Close to the path people are already walking, on a surface that will not shift under a wheelchair. The approach route needs at least 36 inches of clear width per ADA Standards 403.5.1, so units tucked behind equipment or across loose dirt do not meet the standard even if the unit itself does. Our porta potty placement guide covers ground prep and clearance in more detail, and it matters as much for accessible units as for the standard fleet. If you're setting up a construction site services job in Savannah, ADA units get sited alongside general sanitation under OSHA 1926.51(c), not off in a corner of the lot. On paved or municipal ground, placement in the right of way needs confirming with the City of Savannah before delivery. We have not verified a specific permit rule for accessible unit placement, so check with the city rather than assume. Our porta potty permit requirements page has the general framework for that conversation.
Do I need ADA units for a construction site?
Not automatically by headcount alone, but most Savannah job sites plan for at least one anyway. OSHA 1926.51(c) sets toilet ratios by crew size, one facility for 20 workers or fewer, without a separate ADA carve-out written into that specific rule. ADA accessibility requirements come from the ADA Standards themselves, and many general contractors build them into site plans regardless, especially when the public or clients may visit. Renting through construction dumpster rental and temporary fence rental vendors alongside restrooms is common on active Savannah sites, and bundling an ADA unit into that same delivery avoids a second truck run. Rates for accessible units run in their own band separate from standard units, shown below.
| unit | duration | typical price |
|---|---|---|
| standard | day | $150 |
| ada | day | $230 |
| ada | week | $185 |
| deluxe | week | $250 |
Weekend ADA rentals for a Savannah event typically land around $240, based on measured pricing across the market. Full detail on standard unit pricing lives on our porta potty rental cost and porta potty rental per day pages, and monthly job site accounts should check monthly porta potty rental.
Does an ADA porta potty need a sink?
Not by the accessibility standards themselves, but general sanitation rules do require handwashing. 29 CFR 1910.141(d)(2) requires soap and towels or a hand drying device, and hand sanitizer alone does not satisfy it. Pair the unit with a handwashing station rental or portable sink rental to cover both.
Can I rent just one ADA unit for a small event?
Yes. Section 213.2 requires a minimum of one accessible unit any time units are clustered, so a single ADA unit alongside a handful of standard ones satisfies that floor. Check our event restroom rental page for small-gathering setups around Savannah.
What is the difference between ADA and deluxe flushable units?
ADA units are built around clearance and reach, deluxe units around flushing and finish. A deluxe flushable porta potty can also be ADA-configured, but the two features address different needs entirely.
How much wider is an ADA unit than standard?
The turning circle inside is 60 inches under ADA Standards 304.3.1, well beyond the 44 by 48 inch footprint of a standard unit. Door width also increases, from typical standard dimensions up to the 32 inch minimum under section 404.2.3.
Do restroom trailers meet ADA requirements too?
Some do, built with ramps at a 1:12 maximum slope under ADA Standards 405.2 and wide interior aisles. Ask specifically when booking a restroom trailer rental or 4 stall restroom trailer, since not every trailer configuration includes an accessible stall.
