Thank you all for the comments. I was going to email her this, please let me know your thoughts:
Dear ___,
I was in your apartment today for the maintenance problems that we had discussed, and noted clear evidence of smoking: ashtrays with cigarette butts and unit smelled like smoke.
As you know you have a strict no-smoking policy in your lease. I have attached the lease addendum that you signed back in October. I don't know why you would blatantly disregard these lease rules.
At this point, you have 2 options:
1. you voluntarily move out by May 31. This will avoid filing eviction, which is in YOUR best interest because an eviction would go on your permanent record making it very difficult for you to rent other homes. I would strongly suggest you take this route.
2. If you don't do #1, then we have to file eviction. This will go on your permanent record.
I'm sorry to be the bearer of bad news but these are the rules, and the no-smoking policy could not be more clearly spelled out in your lease agreement that you signed. We have no tolerance for smoking -- it damages the unit, it is very difficult to get the smell out, and it is a fire hazard.
Let me know if you have any questions,
