Costa Masnaga, Lecco's Brianza on the line to Monza
In the Lecco part of Brianza, between Molteno and the villages running down towards Lake Pusiano, Costa Masnaga is a place of low-rise houses, workshops and detached homes, where farmland alternates with residential streets built over the last few decades. Lecco, Como and Monza are all a short drive away, which explains much of the demand for housing.
For anyone working in Milan, the most useful link is the railway that runs from Lecco down to Monza via Molteno. In the open public transport timetables, rail stops in the municipality number 1, with 1 train lines. Otherwise people get around by car, on Brianza's provincial roads, which fill up at rush hour. If you are buying a house near the industrial areas, visit on a weekday too, to hear the traffic and noise.
The population is stable: 4,772 residents in 2023, up 0.4% on 2011. The town is younger than average: the mean age is 44.7 against 46.6 in the province of Lecco, and over-65s are 22.6% against 25.2%. Foreign residents account for 7.9%. A large share of the municipal area is built over, a sign of how dense Brianza has become.
Seismic risk is low. Costa Masnaga is in zone 3, like 63 other municipalities in the province, with an expected ground acceleration of about 0.050 g. For houses built between the 1960s and the 1980s, insulation, windows and heating matter more, since they drive energy bills. The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps, and the report traces the land parcel from the address.
