The first thing I do when I buy a property is update the CO detectors and the smoke detectors.

Lately, there have been other issues, such as smoking cigarettes in his unit and playing loud music late at night as well.

Main items of concern:Lease set up: Business to owner, specific items to include - boiler plate or company that can generate for a feeLiability issues and insuranceADA requirements: the owner had stated only required depending on what tenants live in the facility- carbon/smoke alarms - no ramps, etc (seems fishy as in construction rules on ADA are stringent)As the owner do I need any short of license?

The couple that lived in the home smoked so my realtor let me borrow his Ozone generator to help get the smoke smell out (works amazingly) I am adding a new kitchen countertop, faucet, backsplash and repainting the kitchen cabinets.

Condos are not my thing, but this thing is a smoking hot deal.

If you are buying commercial assets like retail in the millions or more in price most brokers co-op so you have a buyer broker on your side.Residential at smaller price points you can run into more newbie type agents that might do anything to make a buck to survive.Commercial brokers many are already multi-millionaires that have been in the business awhile so don't need to (blow smoke up you know where).

She has people living in the unit that are not supposed to be there, she has a dog in the unit although the lease clearly states no pets and her mother (who is not on the lease) continues to smoke in and around the property although the lease clearly states "No smoking".

And of course working smoke alarms (and if gas, carbon monoxide detectors).  

On their application they both said they're non-smoking, however I recently found a few pieces of evidence that one of the tenants has been smoking outside.

One interesting find during the inspection of the "in law" suite was that no smoke detectors were installed in the furnished basement.That being said, this has me concerned about the potential quality of work that went into the rehab, and whether or not licensed contractors/personnel did the work?
