Along with San Fulgencio, a number of other cash strapped municipalities are looking at building works that have been completed without their knowledge. In many cases they will be regularised and the owners will have an increased IBI bill.
On the coast for example, Orihuela council are finding lots of planning violations at the homes of ex-pats in the form of extensions, terraces covered in etc etc. Although much of this work can be regularised, in 14 cases so far, the owners have been ordered to bulldoze the illegal work. They have a choice to do it themselves or the council will do it for them and charge.
The council have also found one villa at La Murada that cannot be regularised and therefore will need to be demolished entirely.
