Necessity of an elevator?

Will be renovating an existing 4 story residential building. Would like to add a 5th Floor. Entrance to building is on the 2nd floor. 1st floor is technically below grade but an occupiable space. there are only 2 units. the first 2 floors will be a duplex. 3,4, and 5 will be a triplex.

One DOB engineer says no need for elevator. another says yes an elevator is required since i am technically over 4 floors even though entrance is on second floor. it seems overkill to add an elevator that will only serve the 3rd floor (entrance to triplex). are there other alternatives in lieu of an elevator?

want to figure these out before filing.

anyone know if there is a way around this? i figured knowledgable brownstoners may be able to help.

thank you in advance.
