Resolve vertical platform lift (VPL) vs. elevator classification disputes with an AHJ

Steps

1. Identify which standard the AHJ is applying: ASME A18.1 covers vertical/inclined platform lifts intended solely for mobility-impaired persons, while ASME A17.1 covers elevators generally.
2. Check the ADA Standards' referenced A18.1 edition (1999 or 2003, per U.S. Access Board guidance) against the edition adopted by the local building code, since a lift compliant under one may not automatically satisfy the other without an equivalent-facilitation determination.
3. Verify the device's travel distance and intended use case against the local building code's specific threshold for when a VPL is permitted instead of a full elevator — treat any specific foot limit as jurisdiction-specific, not universal, since this session found figures varying by source and by device model.
4. When an AHJ disputes classification, document the applicable standard and edition in writing, since where standards disagree the more stringent one generally controls unless the AHJ approves an alternative.
5. Escalate unresolved disputes through the AHJ's formal variance/appeal process rather than relying on self-certification or manufacturer literature alone.
