Steps
Fetch 2010 Standards Section 502 via ada.gov/law-and-regs/design-standards/2010-stds or the US Access Board's Chapter 5 parking guide.
Confirm car space minimum width is 96 inches with an adjoining 60-inch-minimum access aisle.
Confirm van space option A: 132-inch space + 60-inch aisle, or option B: 96-inch space + 96-inch aisle.
Confirm 98-inch minimum vertical clearance for the van route, space, and access aisle.
Confirm access aisle maximum slope is 1:48 in all directions and it must connect to an accessible route.
Known gotchas
Two configurations exist for van spaces (132/60 or 96/96) — either is compliant; both require the same 'van accessible' signage and 98-inch vertical clearance.
Width measurements are to centerlines when spaces are marked with lines, except the end space, which is measured to the full line width.
