We are a converted 200 unit co-op in Queens. One of the former sponsors' rent-stabilized tenants has filed an HP complaint and harassment complaint against his landlord, who is also the management company, and the Co-Op for leaks, mold, and lots of other HP violations.. No one from the Board has appeared at any of the hearings as per the management company. Now the tenant is making a motion for contempt against us. Do we have to notify the co-op's insurer for an order to show cause. The tenant claims the Corporation is responsible for the leaks from outer walls, mold, water damage to his contents etc. We think it is a landlord-tenant matter. Any suggestions>
