Municipal Ordinance Violations.....if you ignore the code enforcement liens they will issue a municipal ordinance violation against the owner, which will result in a warrant for your arrest. 

I'm going into Cadillac arrest!"  

The politicians are all spending their days trying to figure out how to cheat landlords out of their money.The law I'd like to see these morons pass is one that says that a renter living in my house and not paying rent is actually committing theft and that I should be allowed to have them arrested for stealing. 

That fueled a neighborhood rally that led to the drug dealer's, who committed the crime, arrest and conviction.

As far as drugs, I would deal with it in a non-curable breach of contract section such as: Non-Curable Breach of Agreement: Any of the following events will be deemed a non-curable breach of this Lease; (a) Police raid upon your Premises; (b) Your arrest for possession/sale/storage of any narcotic/controlled substance/chemical or herbal contraband in or about the Premises; (c) Failure topermit Owner's entry to the Premises following receipt of adequate notice; (d) Failure to cooperate with Owner or any pest controller/fumigator/exterminator following receipt of notice of such services; (e) Defaults by you causing Owner to serve more than two notices to pay or quit, in any twelve (12) month period; (f) A misrepresentation on your Rental Application; (g) Delivery of any security door/gate key to anyone not party to this Lease.

Whole ordeal cost me over $2500.I also regret, of no ones fault but my own, not researching the area more which I would have avoided the stress of my own safety and the half dozen or so calls I made to police, which resulted in arrests. 

I would think that from an income qualification standpoint, it could only benefit the situation, but be sure to verify all other qualification:  previous evictions, bankruptcy, arrests...or whatever else would be a no-go as per your guidelines.3.
