San Teodoro, La Cinta beach, the lagoon and Tavolara
In summer San Teodoro changes completely: the streets fill up, houses shut for months reopen and every service runs flat out. The town lies on the north-east coast of Sardinia, south of Olbia and its airport, along the main east coast road. Offshore you can see the island of Tavolara, which together with Capo Coda Cavallo lies within a marine protected area.
The best-known beach is La Cinta, a long strip of sand between the sea and the San Teodoro lagoon. The property market is largely a holiday market: small villas, residence complexes and flats in developments built for holidaymakers, many of them empty in winter. There are 25.62 bars and restaurants per 1,000 residents, against 11.00 for the province, and households average 1.76 people. If you want to live here all year, find out what stays open out of season.
The resident population is growing: 5,113 in 2023, up 12.6% on 2011. The average age is 47.9 and over-65s make up 23.2%, against 23.3% for the province. Foreign residents account for 7.4%.
Sardinia is the least earthquake-prone part of Italy: all 26 municipalities in the province are in seismic zone 4, the lowest on the Civil Protection scale, and expected ground acceleration here is about 0.050 g. The climate is mild, and for a house by the sea salt air on steel and render, wind and the state of the roof matter more.
Near the lagoon and along the streams coming down from the granite hills, heavy rain can flood roads and ground floors. The report checks the official flood maps for the address and finds the plot on the Revenue Agency (Agenzia delle Entrate) cadastral maps.

Overview
San Teodoro is a municipality in the province of Gallura Nord-Est Sardegna, in Sardegna. At the end of 2023 it had 5,113 residents, ranked 6 of 26 municipalities in the province.
Earthquakes
For Italy's Civil Protection Department, San Teodoro is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. All 26 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
Compared with the 2011 census, the resident population has grown by 12.6%. The estimated average age is 48 years, in line with the province. 23% of residents are over 65 (the regional figure is 27%). Foreign residents make up 7.4% of the population. On average, a household has 1.8 members.
Income and climate
In tax year 2024, taxpayers in San Teodoro declared an average taxable income of 22,362 euros, in line with the province (21,361 euros). The Italian average is 24,895 euros.
San Teodoro is in climate zone B, with 765 heating degree days: heating may be switched on from 1 December to 31 March, for up to 8 hours a day. The same table puts the town hall at 15 metres above sea level.

Radon and contaminated sites

Landslide and flood hazard changes from one street to the next even within San Teodoro: 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
The cadastral maps for San Teodoro are public: from the address the report finds the sheet and parcel number.
Liveability area by area
