This is completely unacceptable, IANAL but it’s not the tenants’ responsibility to remedy shoddy construction. I recommend reaching out to legal aid clinics and having a lawyer write them a demand letter - ask them if this is a scenario where you can withhold rent. Also, please report to HPD, not sure who your case manager was but I found Albert to be extremely knowledgeable.
As far as providers, I have Assurant renters insurance, it’s $115/year due on signing, if you do file a claim for damages they will likely go after the landlord for damages. Since this is an existing condition, you might want to look into how that would affect your coverage prior to purchasing.
Edit: I’m annoyed for you haha. Please contact your local councilmember, too. I looked him up for you, his name is Oswald Feliz and he used to work as a tenant lawyer! Explain succinctly and professionally the situation, be sure to address him as Councilmember Feliz.
His email is
OFeliz@council.nyc.gov also CC the legislative office at
district15@council.nyc.gov.
If they’re still dragging their feet, next time it rains film a video and send it to the news stations, tag them on Twitter (tag your councilmember, the building management company, the builder, everyone).
