Arzano, a small, densely built town north of Naples

Arzano borders the northern outskirts of Naples and the town of Casoria, in the belt of municipalities where housing runs from one place to the next with no countryside in between. Its territory is small and almost entirely built over, with few green spaces and hardly any free land left, and it is one of the most densely populated places in the province.

People who buy here usually work in Naples or the northern suburbs and come for prices below those of the city. The housing stock is mostly apartment blocks and small condominiums from the years of fast growth, with only a handful of buildings from the old farming village. The individual building matters a great deal, as do parking, street noise and rush-hour traffic. As in much of the Naples area, before completing it is wise to have a surveyor (geometra) check that the property matches the planning and cadastral records, including any past amnesty applications (condoni).

Arzano has been losing residents: 31,938 at the end of 2023, down 8.6% since 2011, or 2,995 fewer people. The population is still young, like that of the province of Naples as a whole, one of the youngest in Italy: an average age of 43.0 against 43.2, with over-65s at 20.5%. Foreign nationals are few, 1.7%, and declared incomes are below the provincial average.

The whole province falls into seismic zones 2 and 3 of the classification set by the Civil Protection Department. Arzano is in zone 2, like 75 other municipalities, with an expected ground acceleration of about 0.162 g. The 1980 Irpinia earthquake damaged many buildings in the Naples area, and some blocks here predate current seismic rules. Asking for the structural completion certificate (collaudo), the design year and any work on the structure is the minimum.

The Revenue Agency (Agenzia delle Entrate) publishes its cadastral maps, so the report finds the plot from the address and measures the distance to schools, pharmacies and shops from that point.

Key points

  • Small, almost fully built-up territory next to Naples.
  • Population down 8.6% since 2011, over-65s at 20.5%.

For Italy's Civil Protection Department, Arzano is in seismic zone 2, a zone where strong earthquakes are possible. Most municipalities in the province (76 of 92) are in the same zone.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.162 g, a medium-high value: the level with a 10% probability of being exceeded in 50 years, on rock.

For anyone buying in Arzano, the building matters a great deal: ask for the design year, whether it met the 2008 seismic standards, and whether any seismic retrofit has been carried out.
