You don't need a main disconnect on a sub panel unless it's in a building separate from the main building AND has more than 6 branch/feeder breakers in it, AFAIK

The disconnect will typically be near the meters for a condo.

That is the answer to the question. Yes there is so a disconnect. In the case of an emergency, all the subs can be turned off at the meter cabinet.

It has more to do with the code requirement to keep the unfused service cables as short as possible. After an disconnect with OCP is provided the cables can be as long as needed to run to each unit.
