I have had several problems with a new condo unit I purchased. The building got its C.O. (Certificate of Occupancy) in May. We moved in mid-July. We were the second family to move in to our apartment. During the summer, we had no AC for a week. Now, during the winter, we have no heat. I have been on management's case (who is one of the sponsor's niece) and the other sponsor's case since last week. The building is trying to correct the problem, but it delays sending the proper repair people quite a bit. What can I do? Any legal remedies I can take? is it worth filing with HPD now? Should I wait until the Sponsor doesn't control the Board and get other unit owners to join me in a lawsuit? Several of us are frustrated.
