Cleveland magistrate Deborah Vasta handed down the maximum fine of $667.25 for failing to comply with smoke alarm legislation.
“It seems a pittance, however it’s not for me to comment on the laws,” she said.
Wayne Godinet, 34, and his boys died after an early morning blaze tore through the Todman Street property.
The children’s mother, Samantha Stephenson, and another woman survived after fleeing as the two-storey home was engulfed in flames.
The fire also destroyed two neighbouring homes and left several people needing treatment for minor burns and smoke inhalation.
The 61-year-old property owner from Tweed Heads was not present when the deadly blaze occurred or when she was sentenced in Cleveland Magistrates Court on Tuesday.
Vasta read Beadel’s guilty plea – which had been submitted in writing – to one count of owner failed to comply with smoke alarm installation.
The 100-year-old house had been relocated from Brisbane, engaging an electrician to do what was required prior to legislation changes, the court heard.
“It’s absolutely no excuse that she failed to keep abreast of the laws required of an investment property owner in having the premises legally wired with smoke detectors after January 2022,” Vasta said.
The deadly blaze left the small Moreton Bay community in shock.
After the fire, relatives travelled from around Australia and New Zealand to pay their respects to Godinet and the five boys at Russell Island.
The children included four-year-old twins with the other boys aged 11, 10 and three.
Police expect to submit a report to the coroner in the “near future”, officers said earlier.
