Well, that's what I though too, balcony is fine. However, condo still trying to enforce "no smoking on balcony" (weed and cigarettes).
No sure if it's legal.
Anyway, the neighbor who complained brought the subject during the annual owner meeting (which happened every year). Luckily she is in the condo below me and all the other owner told her it couldn't come from me since the smoke is going up not down so it couldn't be me.
No more complain since that ????
