Confirm private residence elevator requirements and hoistway door gap hazard rules under ASME A17.1 Section 5.3

Steps

1. Confirm private residence elevators (vertical) are covered by A17.1 Part 5, Section 5.3, distinct from Section 5.4 which covers private residence inclined elevators.
2. Check for post-2016 hoistway-door/car-door gap provisions intended to prevent small-child entrapment between the hoistway door and car door.
3. Reference Nonmandatory Appendix H (Private Residence Elevator Guarding, tied to 5.3.1.7.2) for guarding illustration guidance.
4. Treat any specific numeric gap value (e.g., sill gap, door-to-door gap, ball-reject test dimension) cited in secondary sources as provisional until verified against the exact adopted A17.1 edition text.
5. Check state/local retrofit mandates separately — retrofit of pre-2016 residential elevators for door-gap compliance is typically driven by state or local amendment, not a uniform federal mandate.
