San Sossio Baronia, a village in eastern Irpinia

The Baronia is the eastern part of Irpinia, a district of broad hills and wheat fields opening out towards Puglia, and San Sossio is one of its villages. The built-up area sits on a rise, with the oldest houses gathered at the top and newer ones along the approach roads; around it lie farmland and farmsteads. For work and services people head to Ariano Irpino, Grottaminarda or Avellino, by car.

The point buyers need to focus on is earthquake safety. San Sossio Baronia is in seismic zone 1, the highest on the Civil Protection Department scale, with an expected ground acceleration of 0.253 g; 58 municipalities in the province of Avellino are in zone 1. Many buildings in the area were rebuilt or repaired after the 1980 earthquake: ask for the design date, the structural sign-off and the works paperwork, and for older buildings a structural survey.

According to Istat, the national statistics office, there were 1,481 residents in 2023, down 12.7% on 2011. The average age is 47.1, against 46.2 for the province; over-65s make up 27.8% and foreign residents 3.3%. Declared incomes are below the provincial average.

On the Baronia hills the slopes need careful attention: the report checks the gradient, elevation and official landslide maps at the address, and the flood maps in low-lying areas near streams.

The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps for the whole municipality, so the report can trace the plot and building from the house number.
