As we all know, second hand smoke is never a pleasant experience; tight living quarters make it even worse.
Most people in apartment complexes come in with the notion that there will be some unpleasant smells associated with living with other people, and are not bothered by smoke so long as it is contained. However, sometimes that is just not possible with smoke. If this is the case, it is reasonable that a tenant would become annoyed. But what does what is a tenant to do? They can call the landlord, ask the smokers to stop, plug up any holes, etc, but what happens when they find that their efforts were in vain?
The good news is that there is something you can do. After you let your landlord know that there is a serious second hand smoke issue, preferably in writing, tenant may bring suit against their landlords on the grounds of implied warranty of habitability. Under this theory, courts have looked to the facts and circumstances of the situation to determine whether the second hand smoke is so pervasive as to continue constructive conviction, i.e. your living situation was so badly that you were not kicked out by your landlord but you might as well have been. See Poyck v. Bryant, 31 Misc.3d 699 (N.Y County Civil Ct. 2006).
