Athens four-story apartment building collapses; all accounted for as investigation begins

The collapse occurred at 22 Alkminis Street in the Petralona district of central Athens.
Hospitals on standby for potential injuries included G. Gennimatas, Sotiria, and Tzanio.
A command post was established by the Hellenic Fire Department to coordinate the urban search-and-rescue operation.
The response involved the National Ambulance Service (EKAV) as part of a coordinated multi-agency effort.
Two specially-trained search-and-rescue dogs were deployed to assist in the rubble clearance.
A four-story apartment building collapsed Tuesday morning in Athens' Petralona district, sending clouds of dust through narrow streets and triggering a major rescue operation. Four people were initially feared trapped in the rubble at 22 Alkminis Street, but by midday all four were confirmed safe, according to Detroit News.
Authorities detained five people — including laborers and the owner of a neighboring construction site — within hours of the collapse, Yahoo News reported. Officials are investigating whether nearby excavation work undermined the building's foundations and caused the disaster.
Residents reported hearing loud cracking sounds at around 10:12 AM. The building came down completely just six minutes later. The Hellenic Fire Department activated a Level 3 urban search-and-rescue protocol almost immediately. Thirty firefighters and eight fire engines arrived on scene by 10:40 AM, according to Hellasjournal.
Two specially trained search-and-rescue dogs from the 1st EMAK — Greece's Special Disaster Management Unit — sniffed through rubble voids for signs of life. A Fire Department spokesperson said the operation was "high-risk due to the instability of the neighboring wall" and that crews prioritized the basement apartments during the critical first hour. By 12:45 PM, all four people initially feared trapped were located safe outside the debris field.
Utility crews moved fast to prevent a second disaster. HEDNO, Greece's electricity grid operator, and the Public Gas Company severed all gas and power lines to the 20–24 Alkminis block. The two agencies issued a joint statement confirming the perimeter was secured by 11:15 AM.
Three hospitals — G. Gennimatas, Sotiria, and Tzanio — were placed on standby for potential casualties, The Australian reported. The National Ambulance Service (EKAV) joined firefighters and police at the scene. Athens Mayor Haris Doukas visited the site and said city social services were providing "immediate housing for the seven families displaced."
Greek police detained five people — including the foreman and the owner of the adjacent construction site — under what is known in Greek law as the "Aftoforo" procedure, meaning caught in the act. They face potential charges of negligent bodily harm and violation of building safety regulations, according to Albeu.
One neighbor told local media: "The whole street was shaking for three days because of the jackhammers next door. We told them it wasn't safe." Engineers from the Technical Chamber of Greece say nearby excavation likely damaged the building's footings — the concrete base structures that hold older Athens buildings upright. A forensic report from the Ministry of Infrastructure is expected within 48 hours.
The collapsed building dates to the 1960s — part of a generation of concrete structures now reaching the end of their design life. Petralona has seen a 40% rise in property values over three years, driven by gentrification and a rush to convert old apartments into short-term rentals. That pressure has pushed many owners toward fast, cheap renovations with minimal oversight.
Greek law — specifically Law 4495/2017 — requires rigorous structural checks before renovation work begins. But contractors often use small-scale work permits to skip deep inspections. This collapse echoes a 2024 incident in Piraeus where renovation work killed a 31-year-old off-duty police officer. Opposition politicians are now calling for mandatory safety audits of all buildings over 50 years old across Athens.
