Tenant Personal Property damaged by Water Damage

[Kyle Pallanck]

I recently came across an interesting situation and being a future landlord I was hoping someone would be able to shed light on the situation.

Multifamily Property:

There is a two unit duplex with each unit stacked on top of each other and the top unit is currently being renovated. During the renovation a pipe started leaking water onto the tenants below causing damage to their personal property (Bedding, etc.). The water leaking (Dirty brown water) onto the tenants property caused staining and discoloration to the bedding and mattress. The issue wasn't found immediately until the tenant returned home after work to find the issue so the water had time to seep in.

Now, the tenant is requesting payment for a new mattress ($300). Does the landlord need to pay or would it be the tenants problem?

Thanks for everything in advance and look forward to learning more! (Not sure if it matters, but happened in MA)
