However, no casualty was reported.
According to a neighbour, Siti Rosdiana, 44, she heard someone calling out her name about 4.20pm.
"I immediately went to the ground floor and saw fire coming from my neighbour's unit," she recalled, adding the fire came from a small room where she believed her neighbour had kept her sewing machine.
Siti said she ran up to the first floor and knocked on the door to the premises several times together with other neigbours but nobody was home.
"I think we could have stopped the fire from growing bigger if only we could unlock the door on time," she said, adding the premises belonged to a family of four and that the wife worked as a tailor while her husband worked with City Hall.
"I called the Fire and Rescue Department but my 21-year-old daughter helped me to talk to them because I was too shocked to speak after seeing the fire getting bigger," she said.
A Fire and Rescue team led by Operations Chief Ariffin Harris rushed to the scene following a distress call about 4.34pm.
The fire was brought under control about 30 minutes later.
The cause of fire and estimated loss are still being investigated.
