Tremezzina, the Lake Como shore facing Bellagio

Tremezzina was created in 2014 by merging Lenno, Mezzegra, Ossuccio and Tremezzo, on the western shore of Lake Como, on the stretch that looks across to Bellagio. Within its boundaries are some of the most visited places on the lake: Villa Carlotta in Tremezzo, Villa del Balbianello on the Lenno headland, Isola Comacina off Ossuccio and the Sacro Monte of Ossuccio, a UNESCO World Heritage Site.

For buyers the lake shapes almost everything. Houses along the Via Regina road and on the lakefront have the view and access to the water, but also the traffic of the tourist months. Higher up, the hillside hamlets offer quieter stone houses, often on narrow lanes with little parking. A large share of the homes are second homes or holiday lets. Como and Menaggio can be reached by car along the Regina or by the lake ferries.

There were 4,981 residents in 2023, down 1.9% on 2011. The population is older than the average for the province of Como: the average age is 48.3 against 46.3, and people over 65 make up 27.3%. Foreign residents account for 9.0%. Average declared income is a little below the provincial figure.

Earthquakes are not a concern. All 147 municipalities in the province are in seismic zone 4, the lowest class, and the expected ground acceleration here is about 0.041 g. In older buildings damp, roofs and wiring and plumbing matter more, not least because many houses stay shut for months.

The slopes behind the lake are steep, and in heavy storms the streams coming off the mountains can carry water and debris down to the shore. The report checks landslide and flood risk at the address, including lake floods, and uses the cadastral maps of the Revenue Agency (Agenzia delle Entrate).

Key points

  • Formed in 2014 from Lenno, Mezzegra, Ossuccio and Tremezzo.
  • Over-65s at 27.3%, average age 48.3.
  • The whole province in seismic zone 4.
  • Steep slopes: landslides and lake floods to check.

Overview

Tremezzina is a municipality in the province of Como, in Lombardia. At the end of 2023 it had 4,981 residents, ranked 35 of 147 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Tremezzina is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. All 147 municipalities in the province are in the same zone.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.041 g, a low 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 fallen by 1.9%. The estimated average age is 48 years, higher than the province average (46). 27% of residents are over 65 (the regional figure is 24%). Foreign residents make up 9.0% of the population. On average, a household has 2.1 members.
