I own a house in Portland Oregon and I have an applicant that says they smoke but they’ll do it out side.

Tenant doesn't move anyone else in.90 day inspection ( watch for cleanliness).Pot smoking is very common. 

Are you sure your licensed contractor knows the current smoke and CO detector laws for your area.

Seller's also have to pay an attorney/title company to close, complete a smoke cert, recording costs etc. 

I just had one last week, it was a broken smoke detector. 40 bux.Potential for Difficult Tenants JUST like cash tenants, screening is the key.Property Damage Issues JUST like cash tenants, screening is the key.Harder to Evict Difficult Tenants NO it's not, in OH anyway.Full-Paying Tenants May Turn Away NOT sure what this means?

With the lower tenants smoking downstairs, and the smell of their smoke wafting into the upstairs, we are concerned that smoke smell will turn some potential renters away.I know we need to honor the lease that the tenants were under before we bought the property. 

***There are smoke detectors and a portable fire extinguisher in the retail unit. 

@Julie McCoy, @Lucas CarlI've actually been leaning towards the Smokes just because it's only 3-4 hours away from me. 

There are two types of nuisance, criminal nuisance and non-criminal nuisance:""Non-Criminal Nuisance Example; Smoking and the tenant's tobacco smoke drifts into another rental unit, but only if the landlord prohibits smoking in all units."

After not getting responses to schedule an inspection, I smelled smoke outside the door and went in to investigate.
