Paderna, a hill village near Tortona

Paderna is a small hill municipality in the area around Tortona, in south-eastern Piedmont, at about 300 metres, with Tortona as the reference town for work, secondary schools and services. The village is grouped on a rise surrounded by fields, copses and scattered houses, linked to the plain by provincial roads running down towards the plain around Tortona.

Homes are mostly village buildings in brick and stone, often with a courtyard, and farmsteads with outbuildings. Many have been extended in several stages, so check that what is actually there matches the floor plans held at the land registry and the building permits. Climate zone E brings cold winters; in large houses insulation and the boiler are the first things to look at.

In 2023 there were 186 residents, down 19.5% from 231 in 2011, according to Istat, the national statistics office. The estimated average age is 52.9, against 48.9 in the province of Alessandria, over-65s make up 34.9% and households average 1.71 people. Foreign residents account for 4.8%. Declared incomes are slightly above the provincial average.

Paderna is in seismic zone 3 under the Civil Protection classification, like 127 of the 187 municipalities in the province, with expected ground acceleration of about 0.091 g. For a masonry house built before recent standards, ask what work has been done on the roof and floors and whether the walls are tied together.

On hills, soil and slope matter too: the report checks the official landslide and flood maps for the address and finds the land parcel on the Revenue Agency's cadastral maps.
