just go for it, as long as you're not walking the halls doing it, no harm no foul.
I am afraid that then can in fact change any rental agreement as long as they give the resident a 30 day notice in writting in advance before any changes to the lease can be made. They have in fact done this. Is it correct for them to ban e-cigs no but as with most properties that have smokers there is more damage then most.
I have been in the rental management business for 27 years, so yes if you are renting you all need to read, every lease has a provision that say's as long as 30-day notice is given in writing then yes changes can be made
I think the key here is when they say "lighted" in their definition of smoking. Just don't "light" your high-tech smoking device.
I have the most amusing vision in my head of someone "lighting" their PV and then walking into the leasing office...
The really devious side of me says that you should start looking for another place to live until your lease is expired. After you get moved and get your deposits back, send a thank you note with a little P.S. that says "By the way, I just wanted to let you know that I vaped in the apartment. Bet you couldn't tell, could you?"
Not encouraging you to actually do this. Just sayin'.
