How do i get rid of drain flies?
Everyone I ask says drain flies are a sign of dirty pipes, but this building is literally only 3 months old, grease hasn't even been poured down these drains.

If each sink has a trap then the flies should not be able to get in. So first, check to see that there is a trap and that water is in them. If they are OK then the other possibility is the flies are coming down the vent pipe for the sinks toilets, etc. Those SHOULD attach to the drain pipes behind the water traps, if they were done wrong then that could be how the flies are getting in.

You get limonene citrus oil and pour half a cup down each drain now put drain screens in all your drains bingo no more flies

Get some screen wire, shape it around the drain vents on the roof, slid them up a little, and zip tie them in place . They are not coming up the drain, they are coming down the drain vents .
