The owners of Weston-super-Mare's Birnbeck Pier still owe North Somerset Council £120,000 for the demolition of the fire ravaged Royal Pier Hotel.
The authority stepped in to demolish the seafront hotel which was left in an unsafe state following a fire in 2010.
The former hotel is owned by CNM Estates - the same firm which owns the derelict neighbouring Birnbeck Pier.
Council chiefs had asked CNM Estates to demolish the fire ravaged building and make it safe.
But after no work was carried out, North Somerset Council was forced to step in on health and safety grounds and funded the £120,000 demolition and clear up.
As yet, the money has not been repaid.
North Somerset Council deputy leader Councillor Elfan Ap Rees said: "The council had to step in and demolish the hotel for safety reasons.
"What was left was a dangerous building and we asked the owners to demolish it.
"This cost £120,000 which the council is still owed.
"We expect to recover these costs."

The news of the outstanding money comes at the same time as North Somerset Council announced it is to issue a notice to CNM Estates ordering it to repair the crumbling Birnbeck ier.
The repairs notice orders the owners to return to structure to the condition it was in when it was listed in 1983.
Authority leaders say they were forced to issue the notice after 'exhausting all other options' - a claim that CNM Estates refutes.
The Grade II* listed pier is the only one in the country which links the mainland to an island.
The pier has been closed to the public since 1994 and is now on a Buildings at Risk Register.
The town’s RNLI lifeboat service was forced to move off the island in 2014 after concerns for the crew’s health and safety because of the dilapidated state of the structure.
CNM Estates purchased the pier in 2014 after major redevelopment plans fell by the wayside.

It was already in a poor state following years of neglect.
CNM will be given a timescale in which to carry out the repairs to the pier.
If they are not forthcoming one option could be for the council to compulsory purchase the pier.
A council spokesman said: "Once the repairs notice is served, CNM will have a few months to make repairs to the pier.
"We will discuss any further steps with Historic England and make a decision on future options as and when.
" A compulsory purchase order (CPO) might be one of those options, but can only happen if all other avenues have failed."
The Bristol Live asked CNM Estates for a comment on the unpaid demolition fee but has yet to receive a response.
