Mini splits mounted on back of building

I am considering installing mini splits for my 3-family building in brooklyn. Each floor will have it’s own condenser. Can the condenser be installed on each floor on the back of the building? So for example the 3rd floor condenser would be installed about 25ft above ground level. The 2nd floor’s condenser 15ft above the ground and the 1st floor’s condenser 5ft above the ground.
