PART X
PRIVATE RESIDENCE ELEVATORS

Delete and revise Part X Scope to read as follows:

SCOPE

This Part applies to power elevators that are limited in size, capacity, rise, and speed and are installed in or at a private residence. This Part also applies to similar elevators installed in buildings as a means of access to private residences within such buildings provided the elevators are so installed that they are not accessible to the general public or to other occupants in the building.

NOTE: This Part has been developed to provide a minimum standard of safety for private residence elevators. These elevators are installed for the convenience of those persons who are unable to use stairways. Private residence elevators, while they are usually installed in single-family dwellings, may be installed within a separate apartment in a multiple dwelling where they are not accessible to the general public or to other occupants of the building. It is frequently necessary to install such elevators in open stairwells, as the construction of the building may not provide space for an enclosed hoistway.

Since the size, speed, load, rise, and use are limited, it is possible to provide an adequate level of safety without requiring the equipment to meet the standards in other parts of the Code. Equipment installed for use by the general public is subjected to much more severe and frequent service.

Although private residences are usually exempt from routine inspections, this Code will provide a basis for evaluation of existing equipment during resale or exchange of property. It will also be useful when an "installation placed out of service" is returned to use.

It should be noted that the rules of this Part of the Code do not apply to all power elevators installed in private residences, but only to those that meet the definition for "private residence elevator." All other elevators in private residences are required to comply with all the rules of the other parts of this Code.

All residential elevators shall comply with the following by November 7, 2023.
