How Wide an Accessible Parking Aisle Is

A common planning width is 5 feet for an access aisle beside an accessible stall, and 8 feet beside a van stall. Some layouts share an aisle. Confirm the current standard and the local code. The aisle is not a parking space, and it should sit level with the stall.

Five feet and eight feet are planning widths

An access aisle is the striped loading zone beside an accessible stall, not an extra parking space. A common planning width is 5 feet beside an accessible stall and 8 feet beside a van stall. Some layouts share one aisle between two stalls. Markings and signs are part of the requirement, not decorations you add if paint is left over. These widths are the figures people plan with. Confirm the current ADA Standards and the local code before you stripe, because a blog is not the official. The aisle should be on the same level as the stall so a wheelchair is not climbing a lip. Include the aisle in the paved area. If you only pave the stall rectangles, the aisle becomes a gap or a gravel strip nobody can cross.

The aisle adds square feet and tons

A 5 foot aisle beside an 18 foot stall is 90 square feet. At 2 inches of compacted hot mix and 145 pounds per cubic foot, 5 times 18 times 2 divided by 12, times 145, divided by 2,000, is 15 times 145 divided by 2,000, about 1.1 tons. An 8 foot van aisle on the same 18 foot length is 144 square feet and about 1.7 tons by the same planning math. Those tons are only the aisle. The stall beside it is additional pavement. The plant ticket is the real weight. If two stalls share one aisle, you pave one aisle, not two, and you still cannot park a car in it. Put the shared aisle on the sketch so the stall count does not swallow it.

Level, clear, and connected

The aisle has to stay clear of carts, snow piles, and the dumpster. It has to connect to a route a person can actually use to reach the door. A wide aisle that dead-ends at a curb without a ramp is an unfinished layout. Slope limits apply here as well as in the stall. Check the current ADA Standards and the local official for the flatness and the markings rather than copying a neighbor's lot. If the asphalt overlay will raise the aisle above the sidewalk, mill or design the thickness so the level connection survives. Overlay tons still plan near 145 pounds per cubic foot on the area you pave, aisle included. Say that figure is a planning estimate. Stripe after the final surface is down, not before an overlay buries the lines.

A practical sequence

Plan about 5 feet for an access aisle and about 8 feet for a van aisle, then confirm the current standard.
Keep the aisle clear and at the same level as the stall.
Include the aisle square feet in the asphalt tons.
Ask the local official about markings, signs, and the route to the door.

The mistake to skip

Counting the access aisle as a parking stall, or leaving it unpaved beside a new asphalt stall.

Questions people ask

Is the access aisle a narrow parking space?

No. It is the loading area beside an accessible stall. A common planning width is 5 feet, or 8 feet beside a van stall, and some layouts share one aisle. Confirm the current ADA Standards and the local code. The aisle should be level with the stall, marked, and kept clear. Cars do not park in it.

Do I include the aisle in the asphalt order?

Yes. It is paved area. A 5 by 18 foot aisle is about 1.1 tons at 2 inches and 145 pounds per cubic foot, and an 8 by 18 foot van aisle is about 1.7 tons, as planning estimates. The stall is extra. The plant ticket is the real weight. Stripe the aisle after the final mat is in place.
