Thanks for your question and good afternoon.

If your plumbing caused the damages here you likely are held liable to repair the other tenant's property.It would come down to what you find out as far as the cause of the leak.You may want to go on and report this to your condo insurance and let them deal with any claim and costs to repair.You will likely have to pay the deductible but at least the bulk of the costs to repair would be covered.

If your leak caused the damages then likely your condo policy would take responsibility and pay the claim.

See what brother finds and then if it was your leak then you should contact your insurer and let them resolve it.
