Spiazzo, in Val Rendena on the Sarca river
Val Rendena is the Sarca valley that climbs towards Pinzolo and Madonna di Campiglio, between the Adamello massif and the Brenta Dolomites. Spiazzo covers a central stretch of it, with the main village and some hamlets on the valley floor and the lower slopes. Further down is Tione, the hub of the Giudicarie area for schools and services; Trento is about an hour's drive.
Winter and summer tourists pass through, but Spiazzo remains a community lived in all year round. There were 1,259 residents in 2023, down 4.3% on the 1,315 of 2011 according to Istat, the national statistics office. The average age is 46.9 (45.4 in the province), over-65s are 25.6% and foreign residents 9.7%. Declared incomes are in line with the provincial average.
Buyers need to know one thing that differs from most of Italy. Spiazzo, like all of Trentino, uses the tavolare land register: ownership is recorded in the Libro fondiario (land book), and the maps are not those of the Revenue Agency (Agenzia delle Entrate), which does not publish them here. So the report does not show the cadastral plot and says so, while still providing the other data for the address. Land book extracts can be requested from the competent land registry office or through the notary.
Seismic hazard is low: zone 3 of the Civil Protection classification, like 146 other municipalities in the province of Trento, with an expected acceleration of 0.062 g. The climate matters more, zone F with long, snowy winters, and therefore insulation and heating.
In an alpine valley, streams and slopes count too: the report checks the available official flood and landslide maps for the address and measures distances to schools, the pharmacy and shops.

Even in zone 3, seismic standards apply to new buildings: for an older building, ask about the design year and any structural work.

Landslides and flooding
Landslide and flood hazard changes from one street to the next even within Spiazzo: 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.
Land registry
For Spiazzo the Revenue Agency does not publish cadastral maps: the land registry here uses the tavolare (land book) system. The report cannot give a parcel reference, but it still checks risks, services and transport at the address and states this clearly.
