San Giorgio del Sannio, in the hills south-east of Benevento
San Giorgio del Sannio sits in the hills south-east of Benevento, at around 380 metres, along the roads that run from the city towards Irpinia. Benevento is about ten kilometres away and for many residents it is the place for work, study and the main services; the town still has its own shops and services, also used by the smaller villages around it.
Compared with the inland areas of Sannio, the population is holding up better here: at the end of 2023 there were 9,696 residents, down 1.2% on 2011, and San Giorgio ranks 4 by population in the province. The estimated average age of 45.4 is lower than the provincial 46.5, over-65s are 22.5% and foreign residents 2.3%. Declared incomes are clearly above the average for the province of Benevento.
For buyers, earthquakes are the central issue. San Giorgio is in seismic zone 1, the highest class on the Civil Protection scale, together with 47 other municipalities in the province, and the expected ground acceleration in the built-up area is about 0.253 g. The Apennines of Campania have a long history of strong quakes. For any house, ask for the design year, the rules applied, the structural sign-off and later work; for a building from before the 1980s, paying an independent engineer to look at the structure before you make an offer is money well spent.
Housing is varied: blocks from recent decades in the central area, older masonry houses, and detached homes scattered across the rural districts. Landslides are not rare on the clay hills of Sannio, and the report checks them at the exact address together with flood hazard in the gullies.
The Revenue Agency publishes cadastral maps here, so the report can go from the address to the building's land parcel. The climate zone is D.
