Occupants per sq foot?

[Brandyn Dietman]

Hey y'all! I just had an interesting question from a tenant in a studio apartment.. Single mom with her son who stays every now and again, no big deal they're both on the lease. However, she just came and said her friend needs a place to stay for the summer. And she wanted to ask if it's ok if she stays (she already told her yes and is in the unit for the last day) Her lease states she can have a guest for 2 weeks. I'm planning on making an amendment to her lease with her "guest" on it stating liability and an increase of $30 per month to cover the utilities I cover for another adult. However, she's Ina. Studio apartment.. Is there a Wisconsin statute or Milwaukee county statue that states how many people are allowed per square fm foot? I remember there being a number but I can't find it for the life of me. Thanks!
