What happened to the time that penthouse meant ONE unit on the top floor or on the roof of the building? Only New Yorkers call upper floor units "penthouses." Ridiculous and pretentious. Am I describing New Yorkers?????

You're both wrong. "Penthouse" means a dwelling unit **added on** to the top of an existing building. pent, same root as in append.

There can be more than one unit. But to Aaron2's point, not more than one top floor. Also to Aaron2's point, it's sort of a key point to step the addition back, creating generous terrace space (preferably wraparound). These are bereft of any outdoor space at all ... not even a spitting balcony. So sad.
