McMansions Become 'McApartments,'

It should be noted that this phenomenon happened with Brownstones too.

These days, they are 3-4 apartments.

McMansions don't seem as readily adaptable to dividing into apartments, but a lot of them are going to end up as such, because there is no market for them.

It will have the effect of "urbanizing" those neighborhoods though, exactly the opposite of what was intended by the folks who bought and live in such homes.
