Nearly a year has passed, however, cafe owner David Taylor claims that no repairs have been made to the building since.
Family-run Tonstate Group, who previously owned a section of the building which contained the Elephant House cafe, went into liquidation shortly after the blaze in 2021.
Mr Taylor has 12 more years left on his lease of the property. While he has received £350,000 from his insurance company to renovate the cafe, he cannot start work until the building has been made safe.
He told BBC Scotland that the situation had "become a nightmare".
Mr Taylor said: "I've been inundated with emails and letters from Harry Potter fans asking when the cafe will be reopening and I don't know what to tell them as the liquidator hasn't returned my calls.
"I've also sent a lawyer's letter to them but I've still had nothing back from them.
"Nobody in the building can start refurbishing until structural engineers are appointed by the building owner. The building owner has done nothing for almost a year now."
Liquidator Mike Solomons told BBC Scotland that the company was "addressing issues", and that it would try to assist the building owners and tenants "as soon as possible".
It is believed that the blaze started in the Patisserie Valerie cafe next door to the Elephant Cafe.
A cleaner raised the alarm at around 6am on August 24 last year, after she noticed smoke coming up through the floor.
The level four fire spread across the five-storey building, affecting rental flats, as well as the Oz Bar and Merchants restaurant.
One firefighter was taken to hospital after battling the inferno.
Speaking to the Evening News shortly after the fire, Mr Taylor said: “It’s looking like a bomb has gone off in there, to be honest. From what I can see there are ceilings that have come down and floors on our level caved in.
At the time, he estimated that it would take a few months to return the cafe to its former glory, which he said was “devastating”.
The Tonstate Group, which owned the building before the fire, went into liquidation after a serious dispute between the owners.
Property executive Edward Wojakovski, who owned the company with his former father-in-law, Arthur Matyas, was accused of taking funds from the group.
Mr Taylor said: "I feel really angry and upset that we can't start refurbishing works because we've been caught up in a wealthy family dispute."
A spokeswoman for Mike Solomons told the BBC: "The liquidators understand that the fire at George IV Bridge has left the property owners and tenants in an extremely distressing and frustrating situation.
"Unfortunately, the fire occurred prior to the liquidators' appointment, however the liquidators have and are continuing to seek to address the issues surrounding the fire to try and assist the property owners and tenants as soon as possible."
