4 Adults in my 2 Bedroom: Can I Discriminate?

[Christopher Reynolds]

Hello everyone. I have an apartment for rent now, and I have a caller asking me how many adults I'd allow in this apartment (loaded question). He said it was he, his girlfriend, his sister, and his cousin I think. 4 adults.

I don't have to tell you all the reasons why I dislike this idea. However, I was wondering how I'd know if I could say no to this arrangement legally. I know familial status is a protected class, and if this was 2 adults and 2 kids, it's a no brainer what should happen. However, I wasn't sure what I should do here. Are there maximum occupancy allowances mandated at the state level, or municipal level? I tried searching for official statistics but couldn't find anything.

I told the caller that each applicant would have to be on the lease, each would have to qualify with good credit and references, and each would be jointly and severally liable for rent, should 3 of the tenants move out. He seemed fine with that.

Thanks so much for any help you can provide!
