The alarm was raised after a suspected explosion at 23.27pm local time, 22.27 (GMT).
There are currently no reports of any injuries.
Malmo Police said: ”On site, we have found damage to two apartment doors and a lift.”
The explosion is believed to have taken place in the stairwell of the apartment building.
Local police do not know the cause of the explosion and have called in the national bomb squad for advice.
No suspicious packages or items were seen in the stairwell before the explosion.
The explosion comes just weeks after a nightclub was devastated by a detonation in the Swedish town.
The bomb squad responded to the explosion at the Babel nightclub on November 3.
Police chief officer Magnus Lefèvre said: “There has been some explosion on the club, but we do not know what has been detonated.
“The bomb group and technicians are on your way to investigating it.”
The club was closed at the time and no one was injured.
The explosion followed a similar event almost exactly one year before.
