At least one accessible unit per cluster of portable toilets is the baseline: ADA Standards section 213.2 calls for 5 percent of clustered single-user units to be accessible, with a minimum of one, no matter how small the job site is. San Rafael crews and event planners both need to plan for it up front.
Compliance comes down to space and reach, not just a bigger box. The unit needs a 60 inch turning circle inside per ADA Standards section 304.3.1, a door opening at least 32 inches wide per section 404.2.3, and a stable, slip resistant floor under section 302.1. Grab bars and a raised seat sit at a fixed reach range so a wheelchair user does not have to stretch past section 308.2.1's 48 inch high, 15 inch low limits. Door hardware has to work with a closed fist, not a pinch or twist, per section 309.4. Our ADA accessible porta potty units in San Rafael are built to those dimensions, not just labeled bigger. If you are comparing them against a standard porta potty rental, the difference is mostly in the door width and the interior turning space, not the tank.
The route in has to stay a clear 36 inches, per ADA Standards section 403.5.1, from the parking area or building entrance to the unit door. That means no hose reels, no stacked debris, no generator cords crossing the path. If the ground slopes to reach the pad, a ramp cannot exceed a 1:12 run per section 405.2, which usually means a longer ramp than most crews expect. This is where our porta potty placement guide earns its keep: a unit that meets every interior spec still fails inspection if the approach is blocked or too steep. On sites near downtown San Rafael where space is tight, we walk the path with the site super before delivery to catch this early, because moving a full unit after service starts costs more than planning around it. See our porta potty rental checklist for what to check before the truck rolls.
Start with total toilet count under OSHA 1926.51(c): one facility for 20 workers or fewer on a construction crew, then one toilet seat and one urinal per 40 workers as the crew grows past that. From that total, ADA Standards section 213.2 sets the accessible share at 5 percent, rounded up, with one accessible unit required even on a two-unit job. A 60-person crew running four standard units under 1926.51(c) still needs one accessible unit in the cluster, full stop. Event planners run the same math from expected attendance rather than a headcount; our how many porta potties do I need page walks through both paths. For a wedding at a Marin venue or a race staged through San Rafael, event restroom rental and marathon and race restrooms both need the same accessible ratio, not just raw unit count.
Yes. Section 213.2 does not carve out an exception for weddings, festivals or farmers markets, so any cluster of portable toilets at a public event needs its accessible share same as a job site. Wedding restroom rental and festival restroom rental orders both get at least one ADA unit worked into the layout, and for larger gatherings a 4 stall restroom trailer or 8 stall restroom trailer often includes an accessible stall built into the trailer rather than a separate standalone unit. San Rafael sees enough outdoor events through the year that guests expect it, and a venue coordinator asking about compliance is usually asking about this exact rule. If the event is smaller, a single ADA accessible porta potty placed near the entrance covers it without adding a full trailer.

Pricing depends on how long the unit sits and whether it is delivered alongside standard units or on its own. Full breakdowns live on our porta potty rental cost and porta potty rental per day pages, and longer commitments are covered under monthly porta potty rental. A separate delivery fee applies on top of the unit rate for most orders in San Rafael and towns nearby like San Anselmo, 4.3 miles west, or Larkspur, 5.1 miles southwest.
Yes, typically. An ADA unit's day rate runs higher than a standard unit's, since it needs a bigger footprint and reinforced hardware. Compare it against standard porta potty rental pricing directly before booking multiples for a crew.
Yes. Section 213.2 requires at least one accessible unit regardless of total unit count, so a two or three unit job in San Rafael still needs that single ADA unit worked into the order.
No. A deluxe flushable porta potty adds comfort features like a flush mechanism, but it does not automatically meet ADA's door width or turning circle specs unless built to that standard.
Yes, when they serve the public or a workforce covered by the same ratio. Our 8 stall restroom trailer and restroom trailer rental options can include a dedicated accessible stall inside the trailer.
