      Not just zoning, the average office building needs thorough work for that to happen. Washrooms are centralized and one per floor in an average office building for example, for it to have a bathroom for every apartment, it needs extensive piping.

      It can definitely be done though, I live in such a building myself.

        The piping also needs to be oversized for apartment areas compared to offices.

        Local company made this mistake, raised an apartment building on sewage piping designed for offices. At peak hours in the evening and morning the sewage ended up backflowing into the apartments at the lower levels.
