Diano Arentino, in the hills behind the Gulf of Diano
Behind Diano Marina, in the hills that enclose the Gulf of Diano, Diano Arentino is a hill municipality with its town hall at around 330 metres and houses spread between small hamlets along the road that climbs from the coast. The sea is visible from many spots and is a short drive away, but life here is that of a village in the Ligurian hinterland, with terraces, dry-stone walls and narrow lanes.
Buyers choose between houses in the old hamlets, often on several levels and without parking, and homes scattered across the terraces, with land and a view. Either way, access, parking and the state of the dry-stone walls holding up the terraces all matter. On the slopes and along the streams that run down to the sea, the report measures gradient and elevation and reads the official landslide and flood maps for the exact address.
Diano Arentino is holding on to its residents, and gaining a few: 693 residents in 2023, up 2.2% on 2011. The average age is 49.2, close to the 48.7 of the province of Imperia, and foreign residents make up 13.4%. Average declared income is in line with the provincial figure.
The province of Imperia is split between two seismic zones of the Civil Protection (Protezione Civile) classification: 30 municipalities in zone 2 and 36 in zone 3. Diano Arentino is in zone 2, with an expected ground acceleration of about 0.152 g. In the stone houses of the old hamlets, often joined together, it is wise to have an engineer check the masonry and floors.
The Revenue Agency (Agenzia delle Entrate) cadastral maps are published, and the report finds the land parcel and building from the address, useful for working out which terraces really belong to the house.
