Pietradefusi, Irpinia hills between Avellino and Benevento
Pietradefusi lies in northern Irpinia, the hilly inland area of the province of Avellino, on the low hills that separate Avellino from the Benevento area. The land is gently rolling and farmed, with the main village and several hamlets spread over different hilltops, and both cities are within driving distance for work, secondary schools and hospitals.
For a buyer, the first thing to know is earthquake hazard. Pietradefusi is in seismic zone 1, the highest class on the Civil Protection scale, along with 57 other municipalities in the province, and the expected ground acceleration in the built-up area is 0.250 g. Irpinia has had strong earthquakes before, and many houses were rebuilt or strengthened in past decades: before buying, ask to see the design, the structural sign-off and the paperwork for any strengthening work, as well as the certificate of habitability.
The population is shrinking noticeably. In 2023 there were 1,918 residents, down 19.2% on the 2011 census, or 457 fewer people, according to Istat, the national statistics office. The average age of 48.0 is above the provincial 46.2, and over-65s make up 26.3% against 23.9%. Foreign residents are 8.8%. Declared incomes are below the provincial average.
Most of what comes up for sale is village houses, sometimes large, often with ground-floor storerooms and a plot of land, which need a careful look at wiring, plumbing, damp and insulation. The climate is zone D, with colder winters than on the Campania coast.
The Revenue Agency's cadastral maps are available, so the report can go from the address to the land parcel. Landslide maps for the slopes and flood maps along the gullies are checked for the same address.
