Basics of what we do:Electrical Check: Breakers, spot check outlets, check GFCI outlets, turn on/off lights, check smoke/CO detector. 

If I owned single family (I don't) I'd consider dogs.If you think someone might be a smoker instead of asking if they smoke ask them how many cigarettes they smoke a day (picked that one up on the forum).Check their social media - if you see photos of a dog or cat that's significant (could be a parents' pet so use your best judgement) or photos of them smoking and you'll have your answer. 

Background checks, that's the beauty of listing on FB is you can check out their FB profile & if they have a picture of themselves smoking a bong you can easily skip past that person; if all else fails I know a guy who's wife is a PI and she can run a background check on someone for me for like $20 (it doesn't hurt that she used to work for the state's Department of Criminal Investigation).

At my properties I do not allow smoking, pets, or parties.

Smoking something that really increases the risk of serious complications being used to fight the virus is the height of irony.

Then inspect if they fail to file for eviction. if you didn’t smell cigarette smoke either they are vaping inside (just as bad for property damage), or if you smoke you wouldn’t be able to smell it sadly.  

Other then that, most of the time you’ll just need the Carbon/smoke detectors and fire extinguisher.

& utilities for 3-4 guys with jobs and no pets or smoking.

Anyone have experience using an ozone generator for removing fire smoke smell?
