Police are investigating a house fire at a unit complex in Warring Street at Ravenswood that occurred early Sunday morning.
Multiple crews from Tasmania's fire and emergency services were alerted to the blaze just before 3 am, and it was quickly extinguished.
Police advised the single bedroom unit was unoccupied at the time and no other properties in the vicinity were damaged by the fire.

The house sustained significant damage estimated at $200,000 with police advising the cause of the fire was yet to be determined as of Sunday afternoon.
The fire was the second blaze to occur within 48 hours after a Mayfield woman was charged by police for allegedly setting a caravan alight in an unrelated incident on Friday night.
That fire spread to a house resulting in an estimated $40,000 worth of damage.
The two blazes over the weekend bring the total number of fires to occur in the suburbs of Ravenswood and Mayfield in less than a month to six.
On September 25, a house in Treherne Street at Mayfield became the fourth property to be damaged by fire in less than a week, after a vacant home at Hargrave Crescent in the same suburb was set alight - 24 hours earlier.
The Mayfield fires came only three days after two blazes in Ravenswood occurred, with one reportedly the target of arsonists.
According to neighbours, an unoccupied property at Rosetta Place was intentionally set alight at 4am on September 23.
Four days earlier on September 20, Tasmania's fire and emergency services again attended a separate Warring Street unit responding to reports of a fire.
A neighbour of that property said it was not the first time a fire had been deliberately lit at the home.
The fire was quickly extinguished, but caused about $3000 worth of damage to the property.
Tasmania Police confirmed five deliberately lit fires had been recorded in the past four months.
Anyone with information about deliberately lit fires should contact police on 131 444 or Crime Stoppers anonymously on 1800 333 000.
