Grease Fire - Security Deposit Question

[Mark N.A]

So there was a grease fire in one of our units last night. No one was hurt but the fire did some half-way serious damage, especially since the children's sitter tried to dump the burning grease down the sink.

The insurance deductible is $500.

Here's the question: My partner wants to charge the deductible against the tenant's security deposit.

Anyone have any thoughts on this?
