ADA Parking Requirements in Alabama: Stalls, Signs, and Sizes
· Port City Striping
Accessible parking is the most common compliance problem on Alabama lots — not because owners ignore it, but because the rules are counted, measured, and signed in ways most people have never had spelled out. Here's the whole thing in plain English.
The short answer: you need 1 accessible space per 25 total spaces (the table below scales up), at least one van-accessible space, and a vertical sign at every accessible space. Paint alone doesn't comply.
How many accessible spaces you need
The 2010 ADA Standards set the count by your lot's total:
| Total spaces in lot | 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 |
At least 1 of every 6 accessible spaces (and always at least one) must be van-accessible. Medical facilities need more than the table — outpatient facilities need 10% of patient/visitor spaces accessible, and rehab facilities 20%.
What makes a space compliant
- Size. A standard accessible stall is at least 8 feet wide with a 5-foot access aisle beside it. A van space is either 11 feet + 5-foot aisle or 8 feet + 8-foot aisle.
- The access aisle. It must be marked (hatching is the convention), it can be shared between two stalls, and it can't double as a drive aisle. Painting over an access aisle to squeeze in a stall is a classic violation.
- Location. Accessible spaces go on the shortest accessible route to the entrance, on ground that's firm, stable, and nearly level — slopes no steeper than 1:48 in any direction.
- Signs. Every accessible space needs a vertical sign with the access symbol, mounted so its bottom edge is at least 60 inches above the ground; van spaces add a "van accessible" sign. Signs are what keep the space identifiable when a car is parked on the paint.

"My lot is old — am I grandfathered?"
Mostly no. Title III of the ADA expects existing businesses to remove barriers where it's "readily achievable" — and re-striping a lot is the textbook example of readily achievable. Any re-stripe, re-pave, or renovation is expected to bring the parking up to current standards. In practice: the moment you touch the lot, do the ADA items.
What non-compliance actually risks
- Private lawsuits. ADA complaints are filed by private plaintiffs, and accessible parking is the easiest violation to spot from the street — "drive-by" suits are a real industry, and settling one costs more than striping a dozen lots.
- Federal penalties. DOJ civil penalties for ADA violations run well into five figures for a first violation.
- Failed inspections and stalled deals. Permit renewals, remodels, lender property reports, and new tenants all surface parking compliance.
Against all of that, the fix is usually one visit: paint, hatching, symbols, and a few signs.
The Gulf Coast wrinkle
Compliance fades here — literally. Mobile's sun bleaches blue paint and hatching faster than owners repaint it, so a lot that complied five years ago may not read as compliant today. When you restripe on the normal Gulf Coast cycle, the ADA items renew with it.
