i’m working on a condo/apartment building of 42 units. It has a 4,000 sq ft ground floor consisting of a retail space, lobby, laundry, elevator, stairs, mechanical, and parking space. The residential units are on 4 floors above that and a portion of the parking.

Emial from condo guy:

we need to add a 10x10 storage unit for each unit on the ground floor.

lets do some math: 10x10x42 equals 4200 sq ft.
