Parking and ADA compliance
Verify parking layouts meet ADA requirements and local zoning codes. Helonic checks accessible stall counts, van-accessible dimensions, access aisles, signage, and accessible routes from parking to building entries automatically from your site plans.
Why parking compliance matters
ADA violations carry real legal liability and expensive field remediation.
From site plan to compliance report
Helonic measures every accessible stall, aisle, and route against ADA limits.
Count and classify
The AI reads the site plan or parking plan to count total stalls, identify accessible stalls, and classify van-accessible versus standard accessible spaces.
Measure dimensions
Every accessible stall is checked for minimum width (96 inches), access aisle width (60 inches standard, 96 inches for van-accessible), and proper signage placement.
Trace routes
The accessible route from each accessible stall to the nearest building entrance is traced, checking for proper slope, curb ramps, cross-slope, and obstructions.
Verify ratios
Total accessible stall count is checked against parking lot size per ADA Table 208.2, including the required proportion of van-accessible spaces.
What we check
Coverage across the most frequently cited ADA parking requirements.
Accessible stall count
Calculates the required number of accessible parking spaces based on total lot size per ADA Table 208.2, and verifies the drawings provide the correct count.
Van-accessible dimensions
Checks that van-accessible spaces provide the full 132-inch width (or 96-inch space with 96-inch aisle) and minimum 98-inch vertical clearance at the stall, access aisle, and route.
Access aisle width
Verifies that every accessible stall has a properly sized access aisle that is level, marked, and connects to the accessible route without requiring travel behind parked vehicles.
Signage placement
Checks that accessible stalls have proper signage including the International Symbol of Accessibility, mounted at the required height, with van-accessible designations where required.
Accessible route to entry
Traces the path from accessible parking to the building entrance, verifying compliant slopes (max 1:20 running, 1:48 cross), curb ramps, detectable warnings, and clear width.
Zoning count compliance
Verifies total parking count against project zoning requirements, checking standard stalls, compact stalls, EV charging spaces, and bicycle parking where required by local code.
Why this matters
ADA parking violations are among the most common accessibility complaints filed against commercial properties. Beyond code compliance, they carry real legal liability. The Department of Justice actively pursues ADA violations, and private lawsuits are increasingly common. Fixing parking after construction means re-striping, re-grading, and sometimes re-pouring concrete.
The requirements seem straightforward but the details trip up even experienced designers: van-accessible spaces on the passenger side, access aisles that connect to accessible routes, proper slope at the stall itself. Helonic catches these details systematically so they are resolved during design rather than after the parking lot is paved.
