Hi,

I am working on a parage garage that has 5 floors and an single elevator.

I am trying to understand when the elevator is required to be on an emergency (700) or legally required standby system (701) generator.

If the elevator is not part of required means of egress, does the elevator even need an generator?

Can someone point me in the right direction?

Even if the elevator were effectively powered from a generator, the relevant building codes may still require that the elevator NOT be routinely usable during most varieties of power outage. Certainly not in case of fire or natural disaster.

Go to Chapter 27 of your adopted Building Code and see where Emergency (Article 700) and / or Standby (aka legally required Article 701) power is required based on the occupancy type or unique building application.

Generally you will need Article 701 power if the elevator is used for accessible means of egress (Section 1009), emergency operations (Section 3003), fire service access elevator (Section 3008) and occupant evacuation elevator (Section 3008). It is also needed for high-rise buildings (Section 403.4.8)

This is the latest version if you are curious https://codes.iccsafe.org/content/IBC2024P1/chapter-27-electrical

If the building has a floor that is 4 or more stories above the lowest level of discharge, the elevator is required to be a means of egress, which means that it is required to be on emergency power.

So if you have a building that is 5 or more stories above ground, the elevator should be required to be on standby power

School me on this, shouldn't there be approved plans already in place for a job like this that were called out by an engineer?
IMO, the approved plans should have all the information in them.
However, the engineers and architects usually have boiler plate statements like, Not responsible for this or that, contractors to verify all dimensions, contractor's responsibility to know all applicable codes.

Thank you Ron. This was helpful. After reading the code, it was decided that it will be on standby power.

thanks for the info... do you have a code reference for the 4-level rule?
