I rented an apartment in a complex for ~2yrs. During my tenancy the plumbing for the adjacent laundry room broke and leaked into my apartment ruining some of my clothes and books. This happened twice.
There is a quote in my rental agreement saying that the landlord is not responsible for any damage to personal property (citing water pipes specifically). I was told by the small claims court advisor in my county that this clause is illegal but did not have references for me.
Is such a clause really illegal and if so where can I find the specific law that says so?
How late after the incident can I sue the landlord?
