Building lacks garbage room and alley. How to handle garbage

[Account Closed]

I've acquired an old family building. Mix use. I have a major issue with trash collection. There is no designated trash room. Large barrels currently sit in the elevator landing. Unsitely and smelly. I can't make a room in the basement as the elevator only goes to the ground floor. So it may seem that I have to convert a storage closet on the commercial office floors as the "trash" room. But I fear it will just be smelly and dirty with all the household waste and office waste. The food and liquids really are a hassle that I want to contain.
