Police attended the house on Gilfillan Street in Whyalla Norrie in South Australia when a fire started inside a rear shed at 6.30am Sunday.
It is alleged the remains of a hydroponic cannabis crop was located and investigations are continuing as to whether it contributed to starting the fire.
The shed and contents, including 'a number' of Harley Davidson motorcycles, were destroyed.
The total cost of the damage is believed to exceed $190,000.
The male homeowner, who police say is a member of the outlaw motorcycle gang the Red Devils, was arrested and charged with cultivating cannabis and possessing prescribed equipment.
The 45-year-old received bail to appear at Whyalla Magistrates Court at a later date.
"Police want to remind the public that the growing of cannabis is not only illegal but also poses as a real danger, particularly when being grown hydroponically," a police spokesperson said.
