Sunny Isles Beach’s luxury Regalia condominium, where each unit takes up an entire floor and has floor-to-ceiling glass walls, needs $30 million in repairs due to construction and design defects, an attorney for residents said.

Problems include safety hazards like using the wrong or no screws for balcony railings and putting electrical grills meant only for indoor use on oversized balconies. Other issues include water leaks blamed on design and construction flaws and missing luxury finishes.
