The incident happened late last week when Dumitro Palamaryuk, a Romanian national resident in Via Montegrappa, Brescia, went out onto his balcony to have a cigarette.
The railing came loose so suddenly that he was unable to do anything to arrest his fall.
"It was all over in three seconds," his wife told Corriere. "I saw him lean on the railing, turn around and then fall. It was a horrible."
The father of one was rushed to hospital, but died from severe head injuries shortly after arriving.
Palamaryuk's neighbours told Corriere that he had expressed concern about the condition of the balcony on more than one occasion in the weeks before the accident.
"He had repeatedly spoken to his building administrator and to the landlord about the state of the balcony," said neighbour Michele Lucariello.
Police have opened an investigation into the incident and will be speaking to the landlord and building administrator in the coming days.
Last summer, a 17-year-old German student was killed after falling from a balcony in Tuscany, while earlier this year, residents in Rome had a lucky escape after their entire building collapsed overnight.
