Calculate Parking Spaces & Striping Cost
ADA spaces require wider stall (12 ft) + access aisle + signage. Extra cost: $35–$75 per ADA space.
ADA Parking Space Requirements
Federal ADA law requires a minimum number of accessible spaces based on total lot size. Non-compliance can result in significant fines.
| Total Parking Spaces | Required Accessible Spaces | Van-Accessible Required |
|---|---|---|
| 1–25 | 1 | 1 |
| 26–50 | 2 | 1 |
| 51–75 | 3 | 1 |
| 76–100 | 4 | 1 |
| 101–150 | 5 | 2 |
| 151–200 | 6 | 2 |
| 201–300 | 7 | 3 |
| 301–400 | 8 | 3 |
Standard ADA space
12 ft wide with 5 ft access aisle (17 ft total), or 11 ft wide with 8 ft van access aisle.
Signage required
Each accessible space must have a sign with the ISA symbol, mounted at 60–66 inches above the ground.

Frequently Asked Questions
How much does parking lot striping cost?▼
New parking lot striping costs $0.20–$0.50 per linear foot. Restriping (painting over existing lines) costs $0.15–$0.35 per linear foot. A typical 50-space lot with standard 9×18 ft stalls has approximately 2,000 linear feet of striping and costs $400–$1,000 to restripe.
How many parking spaces fit in a 10,000 sq ft lot?▼
A 10,000 sq ft lot (approximately 100×100 ft) fits roughly 25–35 parking spaces using standard 90° layout with 9-foot wide stalls and 24-foot drive aisles. Actual count depends on lot shape, entrances, and any landscape islands.
How often should parking lot striping be repainted?▼
Parking lot stripes should be repainted every 2–3 years for high-traffic lots, every 3–5 years for low-traffic lots. UV exposure, weather, and traffic volume accelerate fading. Faded lines are a liability issue — ADA lines must remain clearly visible.
What is the ADA parking space requirement?▼
Federal ADA law requires 1 accessible space per 25 total spaces for lots with 1–100 spaces, scaling to more spaces for larger lots. At least 1 space must be van-accessible (with an 8-foot access aisle). Signs must be posted at each accessible space.
