The condominium association for the 66-storey Aston Martin Residences in Miami has filed a Chapter 558 claim alleging widespread construction defects, including crumbling concrete, cracked slabs, leaking balconies and post-tension system problems documented by Epic Forensics & Engineering. A post-tension component reportedly fell onto the pool deck on November 24, 2025 (no injuries), and the association raises concerns about corrosion and exposed reinforcing steel that could pose life-safety risks. Riverwalk East Developments denies the allegations, while a separate lawsuit accuses developer German Coto of failing to deliver promised amenities and of questionable financial dealings, with the association seeking over $5 million and a full financial review.
Owners of Two-Year-Old Aston Martin Residences File Claim Alleging Crumbling Concrete, Leaks and Safety Risks
The Aston Martin Residences, a 66-storey, 391-unit luxury tower at 300 Biscayne Boulevard Way in Miami whose units sold for as much as $59 million, is the subject of a Chapter 558 claim brought by its condominium association. Construction was completed in 2024, and non-developer unit owners assumed control of the association in March 2025.
Association Files Chapter 558 Notice
The association has submitted a formal Chapter 558 notice under Florida law — a required step that gives developers and contractors an opportunity to address alleged defects before a lawsuit is filed. The claim, supported by a turnover inspection from Epic Forensics & Engineering, alleges extensive construction and life-safety issues across the building.
Documented Defects
According to the association's filing and the forensics report, the problems include:
- Crumbling and cracked concrete throughout the structure
- Improperly sloped balcony decks leading to water intrusion
- Deteriorated surfaces and unsealed openings
- Issues with the post-tension system, including a grease cap that reportedly detached and fell onto the pool deck on November 24, 2025 (no injuries reported)
- Corrosion and exposed reinforcing steel that raise potential life-safety concerns
- Alleged deficiencies in core building systems — fire protection, plumbing, electrical and mechanical systems — plus elevators, doors, railings, waterproofing, exterior finishes and the seawall
"Developers are rushing to get these buildings constructed and sold so quickly that one has to question quality control and who's making sure these huge projects are being constructed properly," said David Haber, one of the association's attorneys. "Know Thy Developer — what is in the glossy pre-sales brochure is often not what you end up with."
Developer Response
Riverwalk East Developments has rejected the association's allegations, saying the project was delivered to "premium standards of design and construction." The developer stated that the association's complaint distracts from the association's own unresolved obligations and expressed confidence that the legal process will show the facts and lead to a fair resolution.
Separate Financial and Amenities Dispute
In a separate legal action filed in January, the association named developer German Coto, alleging he failed to deliver several promised luxury amenities and that millions in association funds flowed through undisclosed contracts benefiting the developer and his associates. That suit seeks more than $5 million in damages and a full review of the building's financial records. (Coto is the son of Argentine businessman Alfredo Coto.)
What Happens Next
The Chapter 558 notice begins a period during which the developer and contractors may inspect, offer repairs, or negotiate. If the association remains unsatisfied, it may proceed to file a formal lawsuit seeking damages and remedial work. The association is pursuing millions in damages related to alleged defects and safety risks.
