Question about occupants

[Jane S.]

Recently rented to a family of 5 with 2 adult men unemployed. A little nervous about that but the numbers worked, the women are carrying the financial burden.

When I went there Saturday to do the condition inventory there were 2 little kids there. One 9 months, one almost a toddler. They were the great grandkids of the main tenant, her grandson's kids. They are going to be there every other weekend. They were not listed on the rental apps. 

This is a surprise. Do I consider them occupants, even though they only live there every other weekend? Am I responsible for their safety etc.? I dont know their full names or their parents' names, who don't live there. 

Just wondering as it never happened before, and feeling like the tenants should have informed me about details, parentage, etc.  I dont know if they have legal custody, if the parents are divorced, whats going on. But it means additional wear & tear especially as the babies get bigger. Thank goodness their lease is 6 months.

The house is perfect for multigenerational living but this takes the cake ...
