Remodeling with Dust and tenant

[Tim Jahnke]

I am doing a remodel where I am removing plaster and laths. My up stairs tenant is complaining she is allergic to the dust and I need to remodel both bathroom before I can finish up down stairs because both bathrooms share same drain lines. My concern is some type of hospital bills or other major re-percussions. I want to give some type of legal notice that I cant get sued or she has 60 days to vacate. How does one do this ?
