There's no progression flag made when dropping off Yasmin at Charlie's, so you can take her to the Crackhouse which will be open, and it still makes a checkpoint too.

I'm guessing because there's no cutscene, which is how the game makes progression flags, that it's all just one "level". I tried it on other missions (for example, going straight to the warehouse on "Filthy Business" and even clipping inside the police station, but because there's a cutscene when you get into the van, or when you kill McCormack, it makes a progression flag, so both places are closed until the flags are triggered and those areas become available).
