Boarding house blaze in Sydney's north-west prompts council investigation

A local council is expected to investigate a boarding house in Sydney’s north-west after a blaze broke out overnight.

The fire began just after midnight in the Dundas Valley property, prompting an evacuation of the nine-room building.

Firefighters were called to the scene and began searching the rooms and assisting with the escape of all seven residents.

At one point the roof began to collapse and forced firefighters outside, with one male firefighter suffering minor leg injuries. 

The injured firefighter was taken to hospital and has since been released.

A female resident was also taken to hospital for minor injuries she sustained while escaping, and another man was treated for smoke inhalation.

The cause of the fire has not been determined, but it is believed it may have started accidentally in a bedroom on the top floor of the home.

The boarding house has since come under scrutiny, after residents revealed they had not been required to complete a bond or lease of paperwork upon moving in.

Fire and Rescue NSW have passed on information to Parramatta City Council in order to ensure rules and regulations are being met.

The council stipulates that a property with five or more lodgers must be registered, and is currently investigating whether that is the case.

If convicted of failing to meet regulations, the landlords could face hefty fines.
