Maybe not the same in NYC, but generally even passenger elevators are not required to have emergency power unless they are part of the means of emergency egress (intended to be used during a fire.)
It is up to the authority having jurisdiction to classify what’s emergency and what’s not. And it’s important that they do, because per article 700, non-emergency loads are not allowed to be on the emergency panel. The elevator would either be required to be on the emergency panel or required not to be.
I retired from a large Pa hospital that had twenty two elevators. One could have been considered a freight elevator because it only carried food & supplies one floor from loading dock up one floor to cafeteria. All but one of the other elevators traveled from first floor to top ( 12th ) floor. Was told that JACHO or some other authority only required 50% of the elevators to be on EM power but every one went thru ATS'S to supply all of them with EM power. Was well thought out. Where they had an elevator bank of 4 elevators 2 were on an ATS & the other 2 thru another ATS. Was friendly with the two full time elevator tech who worked there. They were very happy when they remodeled elevators by replacing the old DC motors with AC motors & VFD'S. A lot more reliable and lot less maintenance.
