Gas grill explosion on balcony triggers apartment fire in Rettenberg

A gas grill explosion on a balcony sparked a fire in an apartment building in Rettenberg. The blaze spread to the exterior wall and parts of the roof before firefighters brought it under control. Two residents suffered minor injuries

The incident began when a gas grill on a balcony malfunctioned. Investigators believe a defect in the appliance triggered the explosion, which quickly ignited nearby materials. Flames then reached the building's exterior, damaging the wall and roof structure.

Fire crews arrived promptly and contained the fire before it spread further. While the blaze caused significant structural harm, the two injured residents received treatment for smoke-related issues. Authorities estimate the total property damage at around €50,000. Such incidents are not uncommon in Germany. Over the past five years (2021–2025), around 1,200 balcony fires caused by grills were reported nationwide. Fire service statistics from the Federal Office of Civil Protection (BBK) record between 200 and 300 cases annually, with most occurring in urban areas like Berlin and North Rhine-Westphalia.

The fire in Rettenberg has raised concerns about grill safety on balconies. Investigations will focus on the exact cause of the defect. Meanwhile, the building's residents face repairs and temporary disruptions while the damage is assessed.
