In the future, make sure language in the lease addresses this.You want to avoid having a tenant work on your property for a few reasons: The work may be done poorly and you'll have to redo it; the tenant may become injured doing the work and bring a lawsuit against you; it muddies the waters of your  existing relationship.The most I allow my tenants to do is change out the smoke detector batteries if needed- even that is in the lease.Good luck!

But, she also expected me to find out who was smoking when she thought she smelled smoke.  

One of my SFH renters called me this morning to let me know they had called the fire department because they noticed smoke coming from a vent.  

I am happy to report that they have NO EVICTIONS, no bankruptcies, okay credit scores, no criminal records, no smoking, no pets.

Yes, moving sucks, regardless of whether they work hard or sit home and smoke dope, but it's not the end of the world. 

(coincidentally she had the highest credit score out of all the applicants).Keep in mind if someone has a Section 8 Voucher I give a LOT of leeway on what their credit score is.....I also don't care much about the "income" because I know most if not all of the rent is paid by Section 8......However, if I see a felony or eviction on that background check in the last 5 years.....they are automatically rejected....................If two candidates are fairly equal regarding credit scores, etc....then I will also look at who smokes....anything....at all.......I don't allow smoking of anykind in my rentals in Oakland and Concord....i don't care if it;s legal or not....I will also look at if they have an animal or pet (there's a difference) or not.....I do not allow any pets in my rentals in California......and I will look at how many people will live there....the less the better.In Cleveland, I can't really control all of this because my property manager will deal with this on a day to day basis, but if I happen to get a phone call or text from a potential renter in Cleveland you can best believe I ask these types of questions before I pass the info on to my property manager.

We just went through renovating a cigarette smoker cat spray house (an inherited tenant) and after 3 full scrubbings with TSP, soaking slab and subfloors in vinegar several times over several weeks, then painting subfloors with Kilz, duct cleaning, etc., it finally seems to be resolved.  

A lot of Chinese guys will also have the habit to smoke indoors, if that is not what you want, also make it clear to them. 

Agreement Rules Addendum: this contains all the rules, no smoking, don't wash you car, storage in limited in basement, how to report maintenance, yada yada (my uncle who is a real estate lawyer reviewed and confirmed everything that needs to be in there is, and will hold up in MA court)3.

So maybe some new tech there but I would be surprised.I would even put yeast down the toilet every time I changed the batteries in the smoke detectors.
