Domus de Maria, the beaches of Chia and the south coast

Domus de Maria includes Chia, with its beaches, lagoons and coastal tower, a stretch of Sardinia's south-western coast that is busy in summer. The village itself is a few kilometres inland, at the foot of hills covered in scrub, while the coast is dotted with holiday villages, residences and holiday homes. Cagliari is reached by car along the coast road.

The housing market is driven by tourism. Near the sea, people mostly buy second homes, often in residential complexes with shared areas and rules; in the village are residents' homes, which are simpler. If you buy on the coast, check planning compliance, landscape restrictions, service charges and which services stay open in winter.

There were 1,642 residents in 2023, down 2.0% since 2011 according to Istat, the national statistics office. The average age is 51.6, above the provincial 48.1, and over-65s make up 30.8%. Foreign residents are 2.6%. Declared incomes are above the provincial average.

Sardinia has very low earthquake hazard: all 70 municipalities in the province are in zone 4, with an expected ground acceleration here of 0.050 g. On the coast, salt air, damp and upkeep of windows and systems matter more.

The Revenue Agency publishes the cadastral maps. The report finds the land parcel and checks the official flood maps for that address, worth reading carefully near the lagoons and the streams that reach the sea at Chia.

  • Home of Chia, on Sardinia's south coast.

Overview

Domus de Maria is a municipality in the province of Cagliari, in Sardegna. At the end of 2023 it had 1,642 residents, ranked 46 of 70 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Domus de Maria is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. All 70 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.

Population

The estimated average age is 52 years, higher than the province average (48). 31% of residents are over 65 (the regional figure is 27%). Foreign residents make up 2.6% of the population. On average, a household has 1.9 members.
