If your Metro Atlanta property is open to the public, your parking lot is required by federal law to meet ADA accessibility standards. Noncompliance can mean civil complaints, costly retrofits, and federal enforcement. For most commercial property owners and property managers across Fulton, DeKalb, Gwinnett, Cobb, Clayton, and Cherokee counties, the challenge is knowing exactly what the rules require and having a contractor who can execute them correctly.
How Many Accessible Spaces Are Required
The number of required accessible spaces is based on your lot's total capacity. Lots with 1 to 25 spaces require 1 accessible space. Lots with 26 to 50 require 2, 51 to 75 require 3, and 76 to 100 require 4. From there, the count scales: 101 to 150 spaces require 5, 151 to 200 require 6, 201 to 300 require 7, 301 to 400 require 8, and 401 to 500 require 9. Lots with 501 to 1,000 spaces must designate 2% of total capacity, and lots over 1,001 spaces require 20 accessible spaces plus 1 for every 100 spaces over 1,000.
Of all required accessible spaces, at least one in every six must be van-accessible. If your lot requires only one accessible space total, that single space must meet van-accessible standards. Medical facilities and outpatient care centers carry higher ratios than standard commercial properties.
ADA Parking Stall Dimensions
A standard accessible space must be at least 8 feet wide with a 5-foot access aisle running its full length, for a combined minimum width of 13 feet. A van-accessible space requires either an 11-foot space with a 5-foot aisle, or an 8-foot space paired with an 8-foot aisle, for a combined minimum of 16 feet in either configuration. The 8-foot space with an 8-foot aisle is the more common setup in retrofitted Metro Atlanta commercial lots.
Access aisles must be marked with diagonal striping to discourage parking in them. This is one of the most frequently lost elements when a lot is restriped without a proper ADA layout review. If your access aisles are unmarked or absent, your lot is not compliant regardless of how many blue painted spaces you have.
ADA Parking Space Requirements by Facility Type
ADA Handicap Parking Sign Requirements
Every accessible space requires a sign displaying the International Symbol of Accessibility, mounted so its bottom edge is at least 60 inches above the ground, positioned at the head of the space so it is visible from the driver's seat. Van-accessible spaces require a separate "Van Accessible" designation on the sign or immediately below it.
Signs are required in addition to pavement markings, not instead of them. A lot can have correctly sized and striped accessible spaces and still fail a compliance review because signs are mounted at the wrong height, knocked over, or missing the van-accessible call-out. This is one of the most common compliance failures on older Metro Atlanta commercial properties where original posts have been replaced without reference to current standards.
Surface, Slope, and Georgia Winter Damage
The ADA requires accessible spaces and access aisles to have a maximum slope of 1:48 in any direction, roughly a 2% grade. This requirement intersects directly with pavement conditions in Georgia.
Heavy rainfall and temperature swings cause surface distortion in asphalt over time. When water infiltrates cracks and the surface is repeatedly saturated, it weakens the base layer and can cause settlement that raises and lowers sections of pavement season by season. A surface installed level may develop slopes that exceed 2% after several years of Georgia weather exposure. If your accessible spaces sit near drainage points, expansion joints, or areas that have been patched repeatedly, a slope assessment as part of a restripe review is worth doing.
Georgia's intense UV exposure and summer heat accelerate this degradation. High temperatures break down asphalt binder and speed up surface raveling in parking lots that have not been maintained with regular asphalt sealcoating. A lot that looks intact may have surface issues that affect ADA compliance and stability underfoot.
How a Professional Parking Lot Restripe Addresses ADA Compliance
Not all restripes are the same. A maintenance restripe follows the existing layout. An ADA-compliant restripe reviews the layout against current standards, identifies missing or undersized elements, and repaints to spec. This typically means correcting space counts, widening access aisles, adding van-accessible designations, restriping pedestrian crossings, and painting diagonal access aisle hatching.
At Appell Striping, our parking lot striping crews work from a layout plan before any paint goes down. For properties with surface damage that needs to be addressed first, we coordinate pothole repair before the layout work begins. If your lot also needs sealcoating, the sequence matters: sealcoating must cure fully before restriping, typically 24 to 48 hours in Metro Atlanta summer conditions.
If your lot predates 2010, when the current ADA Standards for Accessible Design took effect, a layout review is overdue.
Frequently Asked Questions
How many ADA parking spaces are required in a parking lot?
The count is based on total lot capacity, starting at 1 accessible space for lots with up to 25 spaces and scaling from there. At least one in every six accessible spaces must be van-accessible.
What are the ADA parking stall dimensions?
A standard accessible space is 8 feet wide with a 5-foot access aisle. A van-accessible space is either 11 feet wide with a 5-foot aisle or 8 feet wide with an 8-foot aisle. Both configurations require a combined minimum width of 16 feet.
What are the ADA handicap parking sign requirements?
Signs must display the International Symbol of Accessibility with the bottom edge mounted at least 60 inches above the ground, at the head of the space facing the driver. Van-accessible spaces require an additional "Van Accessible" designation.
Can freeze-thaw damage affect ADA compliance?
Yes. The ADA requires a maximum slope of 2% in accessible spaces. Freeze-thaw heaving over Georgia winters can distort pavement over time and push previously compliant surfaces past that threshold.
