Subject: Difficult Tenant: Escalating Issues & Safety Concerns (Former On-Site Resident) - Multiple Witnesses - Seeking EvictionBackground:I am a landlord renting out a room in my property.

How do 5-7 people share food space, kitchenware, cooking time, etc?

I'm sure y'all already knew that!

Simply safety screening criteria.

Safety: Owner-occupied neighborhoods can contribute to local safety.

The dishwasher may have a grinder in it for food particles, and the discharge might go into the disposal.

They focus on safety issues, such as wood rot, water damage, and structural integrity of balconies and decks.

The best defense against rats entering your property is to seal off all entry points (holes, cracks in walls), remove food sources (dirty dishes, food left in trash cans), and water sources (like leaks). 

To remedy that, the carpets should be ripped up and sealant applied to the subfloor, at minimum.There are also tiles in the smaller upstairs bathroom that are lifting up and creating a safety hazard; putting a rug on top is not a sufficient solution.The house is in a condition that materially interferes with the health of household members.

I don't think you are going to be able to get insurance for two separate living units in a single-family when they are both illegal and likely do not have the correct egress windows (basement) for fire safety which could subject you to huge liability if something happens to either party.
