No maid in university housing - discover university sims 4?

There was one in the dorm where the Best Friends premade household lives (at Britechester University grounds) but not in the cheapest dorm on Foxbury grounds. But my roommates there are very diligent and considerate and do all the cleaning for my Sim. I did notice however that in the dorm that the maid came, the housemates didn't do much cleaning and tended to have the dishes pile up, not pick up trash on floor and let the toilets stay stinky.
