Sirignano, where Irpinia faces Naples

Sirignano belongs to the Baianese, the strip of the province of Avellino that looks towards Naples rather than to its own provincial capital. The village lies at the foot of the Partenio mountains, among hills planted with hazelnuts and olives, and the Neapolitan plain begins a few kilometres to the west. Many residents work around Nola or in Naples.

The population is young for a village in Irpinia, and the market reflects it: buyers tend to look for flats in recent blocks or houses with some land rather than old homes to renovate. Households are larger than average, with 2.52 people each. For commuting by rail, the reference is the Circumvesuviana, the regional line that ends at Baiano; otherwise people drive.

Istat, the national statistics office, describes an almost stable village: 2,842 residents (2023), down 1.3% since 2011. The average age is 42.1, against 46.2 in the province, and over-65s are 17.6%, far fewer than the provincial 23.9%. Foreign residents are 3.1%. Declared incomes are slightly above the provincial average.

Almost all of the province of Avellino has high seismic hazard: 58 municipalities in zone 1 and 60 in zone 2. Sirignano is in zone 2, with an expected ground acceleration of 0.191 g. For houses built before the latest building codes, ask the seller for the structural paperwork and have a surveyor inspect the property.

At the foot of the hills, the report checks the official landslide and flood maps for the address, as well as the price band, cadastral data and nearby services.

For anyone buying in Sirignano, the building matters a great deal: ask for the design year, whether it met the 2008 seismic standards, and whether any seismic retrofit has been carried out.
