Check a ramp run against ADA 405 / IBC 1012:

- Max rise 30 inches per run (intermediate landing required)
- Landing 60 inches minimum at top + bottom of every run
- Cross slope ≤ 1:48

Slope (≤ 1:12): PASSSingle-run rise (≤ 30″): PASS
Reminder: every run requires a 60″ minimum landing at top + bottom, cross slope ≤ 1:48, and edge protection + handrails per ADA 405.9 / 405.8. Existing-construction alterations may use up to 1:10 over short runs (ADA 405.2 exception).
