I do not know of any apartments that have announced they are medical marijuana friendly but I did recently see an ad on Craig's list for a small 2 bedroom house where the landlord states he is MMJ friendly and had no problem with a small personal grow in the house.

I think the key is discretion. Many apartments have thin walls so sounds and smells will travel. I would not consider growing in an apartment because of how easy it would be for the smell to travel and I would be more inclined to use a vaporizer in that circumstance.

At this point I would not be eager to share MMJ status with a landlord. I am sure there are many out there that do not care as long as you pay the rent, but since there is still a hysteria surrounding MMJ I would keep it on the down low. Maybe after getting to know your landlord, showing you are a good tenant, paying the rent on time and keeping then place up, then I MIGHT speak of MMJ.

Good luck and keep us posted how it goes.
