Medical Marijuana user in mixed residential/commercial building

[Ryan Mangini]

I recently closed on my first deal which is a building with 3 commercial properties on the bottom and 9 apartments on the second floor. A resident on the second floor is a medical marijuana user who vapes for her condition. The bottom floor office complains of smelling weed in the office at times. The building is non-smoking but after researching, it seems the tenant has the right to do so under state fair housing laws (PA) due to reasonable accommodation for her condition. Currently stuck on what to do in this situation. Any input would be appreciated.
