Tenant and Marijuana

[Doug Webb]

Ok so I have a duplex with a top unit short-term rental, and a bottom unit long-term rental.  We are in Seattle, and the bottom unit tenants will frequently sit out on their deck below and smoke marijuana (perfectly legal!), which wafts up to the deck and back rooms of the short-term rental above.  I've been told bluntly that our reviews for the short-term rental are not going to be great from the smell.

Any thoughts on how to reason with the tenants below, given what they are doing is perfectly legal?!
