Lead laws and fair housing laws

[Account Closed]

Hi! I just purchased my first multi family home (3 family, each unit has 3 bedrooms). I moved into one unit, the second unit is staying from the previous landlord, and the third unit is vacant. I’ve posted the third unit to a few rental sites, and since it’s 3 bedrooms, most of the people interested are families with children. 

So here’s my dilemma. Since this is an owner occupied 3 family, I’m excluded from the lead mitigation act as well as the fair housing act. I don’t want to rent to a family with kids for ethical reasons (I don’t have a lead certificate of conformance). But I can’t advertise “no kids” because I’m afraid of getting into trouble with the fair housing act even though I seem to be excluded. Should I just delay renting and spend potentially a lot of money getting the third unit a certificate of conformance? Or is there some other way I can try to avoid that expense and somehow find adult tenants for that unit? Any insight would be greatly appreciated!
