Cost to build an Elevator in a 9 Unit Building?

[Garrett Hogan]

I am currently working on securing a deal for a 9 unit condo new construction building in the boston area. The building will be 4 stories tall about 12k square and will require an elevator. The elevator will have a roughly 8x8 concrete block shaft and elevator inside. Trying to figure out a good ballpark cost for the pre-lim budget.

Does anyone have experience building an elevator of this size? What did it cost you?
