@John Chan - I had a 10+ year chain smoker in one unit that I inherited.  

There is 1 smoker on the first floor and it is awful.  

If you are not a smoker and your other tenants are not smokers then it can be a big problem.If you get this lady to leave plan on de-greasing the ceilings, walls, ductwork etc. to get the film of smoke out.Either way it sounds like you are going to be spending a lot of money in the future so plan for it now.

There's a meet-up for BP members on June 30th from 6-9 at Rally Point Sport Grill in Cary (1837 Harrison Ave) so if you're free come on by.

We've had trouble with marijuana smokers getting stoned or flaking off on the job. 

They are required to take inside THEIR lawn furniture, fire pit, bikes, container pots etc etc etc...I am to cut down potential flying coconuts from palms, take into storage kayaks, hammocks, BBQ grills etc...as far as panels themselves, I wrote that they are encouraged to install the panels (I don't expect them to), but it is my discretion whether I will do it or not, no guarantees. 

PUB AND GRILL off of Camp Bowie in Fort Worth.  

All, Looking at a house that has a bad smell in it, they had dogs and a smoker.  

The Capital Grille (in Rosemont) is an excellent restaurant with awesome steaks.

We will re-pipe flute pipe, electrical, refrigeration piping, install Aprilaire media filters and add grille with duct work through the wall into the finished area of the basement.
