ADA Accessible Parking, Explained in Plain English
If you manage a commercial property, accessible parking compliance is your liability — not your painter's. Here's what the requirements actually mean, so you know what you're paying for.

Careful Restriping, Done Right the First Time
Lots get restriped over and over with the same layout, even after the rules change or the lot's space count changes, which can leave property managers exposed without knowing it. Before we repaint, we walk your existing layout with you and note your accessible stall count, aisles, and signage, so we can re-mark them accurately and consistently. For a new or reconfigured layout, we recommend confirming requirements with your local building official or an accessibility professional first.
Step One
How Many Accessible Spaces Does Your Lot Need?
The number of required accessible spaces scales with your lot's total parking count — not a flat percentage. Here's the federal standard table:
| Total Spaces in Lot | Minimum Accessible Spaces Required |
|---|---|
| 1–25 | 1 |
| 26–50 | 2 |
| 51–75 | 3 |
| 76–100 | 4 |
| 101–150 | 5 |
| 151–200 | 6 |
| 201–300 | 7 |
| 301–400 | 8 |
| 401–500 | 9 |
| 501–1,000 | 2% of total spaces |
| 1,001+ | 20, plus 1 for every 100 spaces over 1,000 |
Source: 2010 ADA Standards for Accessible Design, Section 208.2. This is the federal minimum. Tell us your total space count and city and we'll tell you what applies — federal and Florida both.
Step Two
The Van-Accessible Ratio
Not every accessible space can just be a standard accessible stall — a portion have to be van-accessible, meaning wide enough (or paired with a wide enough aisle) for a vehicle with a side-mounted wheelchair lift or ramp to deploy.
- At least 1 in every 6 accessible spaces (or fraction thereof) must be van-accessible, with a minimum of 1 van-accessible space in any lot that has accessible parking at all.
- Van-accessible spaces need 98 inches of vertical clearance at the space, the access aisle, and the vehicle route to and from the space.
Step Three
Stall & Access Aisle Dimensions
| Space Type | Minimum Width | Required Access Aisle |
|---|---|---|
| Standard accessible (car) | 96 in (8 ft) | 60 in (5 ft) adjacent aisle |
| Van-accessible (Option A) | 132 in (11 ft) | 60 in (5 ft) adjacent aisle |
| Van-accessible (Option B) | 96 in (8 ft) | 96 in (8 ft) adjacent aisle |
Access aisles must run the full length of the space they serve, connect to an accessible route, and be marked (typically with diagonal hatching) to discourage vehicles from parking in them. Two adjacent accessible spaces can share a single access aisle.
Surface slope for accessible spaces and aisles is capped at 1:48 (about 2%) in every direction — steeper grading is a common compliance failure worth checking for before striping.
Step Four
Signage Requirements
- Every accessible space needs a posted sign with the International Symbol of Accessibility, mounted so the bottom of the sign is at least 60 inches above the ground.
- Van-accessible spaces need an additional "Van Accessible" designation on or below the sign.
- Signs must be visible from a vehicle parked in the space and can't be obstructed by landscaping, other signage, or parked cars.
- Pavement stencils (the painted symbol on the ground) reinforce the sign but generally don't replace the posted sign requirement.
We handle both the pavement stenciling and can coordinate post-mounted signage as part of a restriping or stencil job.
