For example: Via Giacomo Matteotti 1, Osoppo.

Osoppo, the fortress above the Tagliamento

The fortress hill, rising on its own from the plain on the left bank of the Tagliamento, is Osoppo's landmark. The village lies at its foot, where the valleys open out onto the Friulian plain, a few kilometres from Gemona; Udine is about half an hour away and the motorway to Tarvisio and Austria runs through the area. Next to the village there is an industrial zone that also provides work for the surrounding municipalities.

The village was almost entirely rebuilt after the 1976 earthquake, and that shows in its housing: many homes date from the reconstruction, with structures designed for seismic risk, and few are genuinely old. Buyers mostly find detached and semi-detached houses with gardens. Near the Tagliamento and the channels, the report checks the official flood maps for the address.

There are 2,783 residents (2023), down 7.4% since 2011. The average age is 48.0, a little below the province of Udine (48.5), people over 65 make up 26.1% and foreign residents 8.6%.

Osoppo is in seismic zone 1, the highest, like 18 other municipalities in the province, with an expected ground acceleration of 0.257 g. For a reconstruction house, ask for the original design and the engineer's sign-off; for a house built or extended later, the structural permits for that work.

The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps, so the report goes from the address to the parcel and links constraints and services to it. The climate is zone E in the Italian classification, with cold winters.

For anyone buying in Osoppo, 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.
