This gets into an interesting discussion as to when something has to be "brought up to code". This might be worth its own question/thread, but I'll put it out here anyway.
In most jurisdictionsmany areas (your mileage may vary), your local jurisdiction/inspector may require that as part of a major remodel of a bathroom or kitchen for example requires that, that the bathroom/kitchen be made code-compliantbrought into compliance with the current codes. For a kitchen, this might mean having to provide 2 20-amp GFCI protected circuits for counter outlets, even if there was only a single 15-amp non-GFCI circuit there originally. In a bathroom, it might entail providing the proper venting.
OP says his condo was completely remodeled. To me that means it needed to be brought up to current code requirements, which means having the bathroom properly vented. But being a condo unit, this may not have been practical.
The gray area is what differentiates a minor update from a major renovation. Tearing a bathroom down to the studs is definitely a major reno. Replacing a toilet - no. Painting the room, NO.
