MEA stands for: Materials and Equipment Acceptance
There is no MEA requirement or any other pre-approval process for platform lifts in NYC. They must be permitted and inspected by the Elevator Division just as a commercial elevator.

For plans review simply put on drawings ‘to be filed under separate elevator permit’. We do get requests for MEA#s from time to time even though the process has not applied to wheelchair lifts for over 20 years. See the city’s website MEA index and you will find wheelchair lift as a category but only one item listed that is obviously a mistake and has nothing to do with wheelchair lifts.
