The report looks at the exact point: landslide and flood risk, seismic zone, price per square metre for the area, services and nearby stops.

For example: Via Dante 7, Milan.

Carbonia, a town born with the mine

Carbonia is a planned town: it was inaugurated in 1938 to house the miners of the Sulcis coalfield in south-west Sardinia. Its layout, with broad squares and rationalist buildings, still reflects that origin, and the great Serbariu mine is now a coal museum. Carbonia shares the role of capital of the province of Sulcis Iglesiente with Iglesias, in an area that also looks out towards the islands of Sant'Antioco and San Pietro.

Such a young town has a housing stock with a clear history: the town was built from the late 1930s onwards, and its original core is less than a century old. For a buyer, the most useful questions concern the state of repair, the work carried out over the years and the energy class shown on the energy performance certificate (attestato di prestazione energetica, APE). The report lists the documents to request, from the compliance declarations for the electrical and heating systems to the certificate of habitability (agibilità).

The report then adds the checks that depend on the exact spot: landslide and flood hazard from the official plans, elevation and slope of the ground, and nearby services.

On earthquakes, the information is short. The whole province of Sulcis Iglesiente, 24 municipalities, is classified in seismic zone 4, the minimum level.

The land registry is the standard one: the Revenue Agency (Agenzia delle Entrate) publishes cadastral maps for Carbonia, and the report derives the land parcel from the address. As always, the data describe the plot and the building; for an individual flat you need the cadastral record (visura) and floor plan (planimetria catastale).

Key points

  • Town founded in 1938 for the Sulcis miners.
  • Buildings from the 1930s onwards: check condition and energy class.
  • All 24 municipalities in Sulcis Iglesiente in seismic zone 4.
  • Joint provincial capital with Iglesias.

Overview

Carbonia is the capital of the province of Sulcis Iglesiente, in Sardegna. At the end of 2023 it had 25,971 residents, ranked 0 of 24 municipalities in the province. 22% of the province's residents live here.

Earthquakes

For Italy's Civil Protection Department, Carbonia is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. All 24 municipalities in the province are in the same zone.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.050 g, a moderate value: the level with a 10% probability of being exceeded in 50 years, on rock.

In zone 4 the risk is low, but for an older building it is still worth asking about the state of the structure.

Landslides and flooding

Landslide and flood risk changes from one street to the next, even within the same municipality: for this reason we do not summarise it as a single figure for the whole of Carbonia.

The report checks the exact address against the ISPRA national maps and tells you in plain words whether the building falls within an at-risk area. The official map is also available on IdroGEO.

House prices

We do not publish price tables by municipality. The report gives the minimum and maximum price per square metre for the address's zone, from the Revenue Agency's OMI valuations, with the reference half-year. It is a range for the zone, not the value of a specific home.

Population

Compared with the 2011 census, the resident population has fallen by 10.1%. The estimated average age is 51 years, in line with the province. 33% of residents are over 65 (the regional figure is 27%). Foreign residents make up 1.7% of the population. On average, a household has 2.1 members.

Public transport

We do not yet have open public transport timetables for this municipality: the report says so explicitly, without inventing distances.

Land registry

The Revenue Agency publishes the cadastral maps for Carbonia: the report finds the building's parcel, that is its sheet and parcel number, starting from the address.
