Striping ADA Passenger Loading Zones

An accessible passenger loading zone is a marked area where a vehicle can pull up so a passenger using a wheelchair or mobility device can transfer to and from the vehicle on level, protected ground. It is not the same as an accessible parking space. A parking space is where a driver leaves a vehicle and walks away. A loading zone is a drop-off and pick-up area, common at hospital entrances, hotel canopies, medical clinics, senior facilities, schools, and venues that move people in and out by van or shuttle.
The two get confused on plan sheets all the time, but they are striped differently and serve different functions. This guide covers how an accessible passenger loading zone is marked, the dimensions that govern it, and when your site is actually required to provide one. For where loading zones fit in the broader accessibility picture, see our pillar on ADA parking compliance in Oregon.
An accessible passenger loading zone has two parts that work together: the vehicle pull-up space and the access aisle alongside it.
| Element | Requirement |
|---|---|
| Vehicle pull-up space length | At least 20 feet long |
| Access aisle width | At least 60 inches (5 feet) wide |
| Access aisle length | Runs the full 20-foot length of the pull-up space |
| Access aisle position | Adjacent to and at the same level as the pull-up space |
| Vertical clearance | At least 114 inches along the vehicle route to, at, and from the loading zone |
The 114-inch vertical clearance is the detail people forget. A high-roof accessible van needs overhead room to reach the zone, sit in it, and leave it. Low canopies, drive-through overhangs, and parking-structure beams can quietly defeat an otherwise perfect loading zone.
Marking a loading zone is straightforward once the dimensions are set, but precision matters because the access aisle must read clearly as a no-park zone.
The same hatching discipline used for parking access aisles applies here. If you want the full treatment on aisle width, hatch spacing, and no-park markings, our ADA access aisle striping spec covers it in depth.
The loading zone and its access aisle should be close to level. Excessive slope makes a wheelchair transfer dangerous, and standing water in a low spot signals a grading problem. As a working target, the surface should hold to a maximum of 2 percent slope in all directions across the loading zone and aisle, the same tolerance that governs accessible parking stalls.
A loading zone is only useful if it connects to the door. The access aisle has to feed a continuous accessible route, no curb without a ramp, no step, no break in the surface, leading to the accessible entrance. A perfectly striped zone that dumps a wheelchair user at a six-inch curb is not compliant. Our guide on the accessible route from parking to the door explains how that connection has to hold together.
Not every site needs an accessible passenger loading zone. The trigger is generally tied to whether your facility provides a passenger loading zone at all. The principle under the 2010 ADA Standards is that where loading zones are provided, accessible ones must be too. Certain facility types are specifically called out:
If your site has a canopy drop-off, a covered entry lane, or a valet stand, you are very likely in loading-zone territory. Oregon code may add specifics on top of the federal baseline, so a site survey is the right way to confirm whether your particular entrance requires one and how many.
If your medical office, hotel, school, or venue has a drop-off lane, it likely needs an accessible passenger loading zone striped to spec, and tied to an accessible route. Cojo Excavation & Asphalt lays out loading zones with the correct 60-inch aisle, 20-foot length, hatching, and route connection.
