Compliance Requirements
For single- and two-family dwellings in California, elevators are not required by code, but where installed, there are specific compliance requirements:
- Elevators installed within a residential dwelling unit, or serving just one such unit, must comply with the California Code of Regulations, Title 8, Elevator Safety Orders. This governs design, construction, installation, and safety features such as hoistway enclosures and door protections.
- Private residence elevators must comply with Section 11B-409 of the California Building Code and ASME A17.1 safety standards. Operation must be automatic, and elevator cars must provide a clear floor space of at least 36 inches by 48 inches, meeting additional accessibility and safety criteria for car doors, gates, call buttons, and floor surfaces.
- For new elevators, emergency operation with Phase I recall and Phase II emergency in-car function are required.
- Standby power is generally not required for single-family applications unless furnished, but if provided, certain transfer requirements apply.
- If an elevator is provided as part of a multistory unit in a building with more than two units, additional adaptability and accessibility requirements may apply, including ensuring adaptable design and that elevator service is to all floors with dwelling units.
- Where elements of an existing elevator are altered, upgrades must extend to all linked elevators.
