Sant'Agnello, citrus gardens and coast next to Sorrento
Sant'Agnello and Sorrento run into each other without a visible border: the same tufa terrace ending in sheer cliffs above the sea, the same walled lemon and orange gardens, the same hotels looking across the Bay of Naples to Vesuvius. Sant'Agnello is the more residential part of the Sorrento plain, with villas, private parks and a station on the Circumvesuviana railway to Naples.
The housing market is shaped by tourism. Space is tight, new building is rare, and some homes are used for short-term lets; anyone buying to live here faces high prices and scarce parking. There are 8.26 cafés and restaurants per 1,000 residents against a provincial rate of 4.49, and in summer the peninsula's roads clog up.
There are 8,593 residents (2023), down 4.8% since 2011. The population is older than the Naples average: an average age of 45.3 against 43.2, with 22.8% over 65 against 20.0%. Foreign nationals make up 3.3%, and declared incomes are above the provincial average.
Compared with most of the province of Naples, where 76 municipalities are in seismic zone 2, the Sorrento peninsula has lower hazard: Sant'Agnello is in zone 3, with expected ground acceleration in the built-up area of about 0.098 g. In villas and historic buildings, the tufa structures, the floors and the alterations made over time still need checking.
The more serious issue is the coast. The tufa cliff above the sea is prone to rockfalls, and the gullies that cut through the plain carry storm water. The report checks the official landslide and flood maps for the exact address and identifies the cadastral parcel.

Earthquakes
For Italy's Civil Protection Department, Sant'Agnello is in seismic zone 3, a zone where strong earthquakes are possible but rare. Only 16 of 92 municipalities in the province are in zone 3.

Even in zone 3, seismic standards apply to new buildings: for an older building, ask about the design year and any structural work.

Liveability area by area
The Vicinalia liveability index runs from 0 to 100 and looks at the place, not the people who live there: services within walking distance, transport, green space, natural hazards, air, quiet, buildings and connection. Here it is worked out at the centre of each of the 28 inhabited census areas in Sant'Agnello. Half of the residents live in areas scoring 61 or more.
