On top of the arbitrary square footage requirements that wlesieutre already mentioned, in a lot of cases it boils down to windows per room requirements, as well as the typical <x> requirements per room, where rooms like kitchen and bathroom are the most problematic.

While I'm generally not a big fan of regulations, I get that there are definitely well-intentioned regulations for legitimate problems, such that landlords weren't allowed to cram too many people into too small a space, or demand that too many people share too few kitchens and bathrooms, but for those who choose the path for themselves, those self-same regulations are burdensome.
