Clean and safe home for rent

Whenever there is a need for me to find new rental homes for my family, I want to ask the landlord if a particular place is that much clean. I also need to ask if the previous owners are smokers or not as I want a smoke free home. I may sound too fussy but I just want a clean home for my family. And to think that I will be renting, I want that my money will be worth it with the cleanliness as well as I want a safe new place to live with my husband and kids.
