Owners of properties across the Bath area that have been vacant for more than 10 years will be charged a 300% council tax premium to encourage them to bring them back into use.
In April 2013, Bath & North East Somerset Council levied a 50% council tax premium on homes that had been vacant for two years or more.
From April last year, that 50% increased to a 100% premium for properties vacant between two and five years and a 200% premium was levied for properties empty more than five years.
The council is now tackling long term empty properties by increasing the levy on council tax to 300% on properties that have been vacant for 10 years or more.
This latest change will come into effect on Thursday 1st April.
The council is also highlighting the advice and financial support it currently offers to owners of empty homes, through loans, grants and VAT reduction.
There is also advice and practical support available helping owners to avoid enforcement action.
There are currently over 200 long term empty homes in B&NES that are subject to a council tax premium, with 24 of them having been empty for 10 years or more.
Councillor Tim Ball, cabinet member for Housing, Planning and Economic Development, said: “Unoccupied homes can have a negative impact on our communities and our landscape.
“They can be a magnet for anti-social behaviour and can devalue neighbouring homes, as well as being an unnecessary drain on public services.
“We have a growing housing need in B&NES and unoccupied homes are a wasted resource we cannot afford.
“By increasing the council tax premium on properties that have stood vacant long-term, we want to encourage owners to make their properties available to become much-needed new homes for other residents.
“We have a range of tailored support and advice available to help people do this if they are struggling or feel overwhelmed about getting started.”
The current total number of properties empty for six months and over in Bath and North East Somerset stands at 814.
