Derelict properties are being knocked down under orders from Arun District Council.
The action was taken as the council stepped up its crackdown on the unoccupied houses.
Councillors have been told the legal authority to demolish three of the empty dwellings was issued last year.
One property was razed to the ground by the council. Another’s owner carried out the work. The owner of the third property has appealed against the order.
The action in 2019 – reported to councillors last week – follows the first of the houses to be demolished the previous year.
Nat Slade, Arun’s group head of technical services, said: “Empty homes represent a wasted resource and can have a negative impact on local communities.”
The latest figures show 394 homes in the Arun district were empty last April. That was after 283 had been brought back into use between April, 2014, and the end of last year through the work of the council’s empty homes officer, Helen Stevens.
Councillors agreed the enforced sale procedure should be updated.
