@Matthew Paul Lots of drugs. time is irrelevant at some point

Next week got a notification on door about having drug activity in hallway of billding.

If, after inspection, you decide you don't think the tenants are a good fit (hoarders, signs of drug use, etc.) you an always put in the contract that the property is to be delivered vacant.

There was a small fire in the downstairs den area so I'm thinking that it might have been a drug lab related fire because it is selling for so cheap.

If they refuse, evict them and get them out.You may also considering screening all your current occupants to clean out any drug dealers, sex offenders, etc.

You can always add a provision in your lease for your tenants to provide that consent by signing the agreement, but not for their associates showing up on the premises.Based on your description, I myself could be thrown in jail instead of the drug dealers I am recording that are conducting illicit activities inside the vestibule of my own building.

Check this out:  State Clan Lab Decontamination LawsTwenty-five states have enacted clandestine drug lab assessment or clandestine drug lab decontamination laws, or both.

It wasn’t from one of the guys routinely drug through the paper and court (another reason to be a little cautious).  

The mother died without a will and the daughter had so many other issues at the time that she just couldn't deal with it, she is relatively young and drugs were involved w her mother's death, so there are a lot of issues here. 

Only to get a phone call from the office manager telling me that he used my window money to buy drugs and that he never ordered my windows.Best of luck.
