Piossasco, below Monte San Giorgio south-west of Turin
Piossasco sits where the Turin plain runs into the first hills, at the foot of Monte San Giorgio on the south-western edge of the metropolitan area. Turin is about twenty kilometres away and many residents work in the city or in the towns around it. The place has grown mainly as somewhere to live: detached houses and small blocks of flats on the flat ground, a compact old core, and scattered homes on the lower slopes of the hill.
Buyers are really choosing between two settings. On the flat, roads are easy and services close by; on the flanks of San Giorgio you gain greenery and views, but the slope of the plot, the condition of retaining walls and winter access all matter. Piossasco has no railway station and most people reach Turin by car, which is worth factoring in if anyone in the household commutes.
At the end of 2023 there were 17,952 residents, down 1.3% on 2011, or 234 fewer people: in practice a stable population. The estimated average age is 46.5, below the provincial 47.4, and over-65s make up 24.7% against 26.4%. Foreign residents account for 5.0%. Declared incomes are slightly below the provincial average.
Seismic zones are set by Italy's Civil Protection Department (Protezione Civile). In the metropolitan area of Turin most municipalities, 271 of them, are in zone 3 like Piossasco; the other 41 are in the lowest zone. Expected ground acceleration in the built-up area is about 0.093 g, a moderate value. For a house from the 1960s or 1970s it is worth asking for the structural drawings and whether any strengthening work has been done since.
The Revenue Agency (Agenzia delle Entrate) cadastral maps cover the municipality, and the report goes from the address to the plot. On the hillside and along the streams running off it, landslide and flood hazard varies from spot to spot, so it is checked for the address rather than for the town as a whole.

For Italy's Civil Protection Department, Piossasco is in seismic zone 3, a zone where strong earthquakes are possible but rare. Most municipalities in the province (271 of 312) are in the same zone.
In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.093 g, a moderate value: the level with a 10% probability of being exceeded in 50 years, on rock.
Even in zone 3, seismic standards apply to new buildings: for an older building, ask about the design year and any structural work.

Radon and contaminated sites
Piossasco is not among the radon priority areas designated by the Regione Piemonte in 2023. Radon varies from building to building and can only be known by measuring it, especially on ground floors and in basements.
Official databases list 3 contaminated sites, or sites still under investigation, in Piossasco, and one more has been cleaned up or closed. The report tells you whether one is close to the address.
Landslides and flooding
Landslide and flood hazard changes from one street to the next even within Piossasco: the report checks the address against the ISPRA maps.
House prices
The Revenue Agency's price ranges per square metre (OMI) apply to zones, not to whole municipalities: the report gives the range for the address's zone.
