Lake Como, Garda or Maggiore? What Really Differs When You Buy a House by an Italian Lake

By Patrick · 2026-10-22

Choose a lake by what you will live with, not by its name. The Brescia shore of Lake Garda costs almost twice as much as Lake Como on official values, Garda sits in a higher earthquake zone, and the steep shores carry far more landslide and flood exposure than flat southern Garda. On every lake, the shoreline and any jetty belong to the state.

Lake Como, Lake Garda and Lake Maggiore look alike in photographs and are very different to own. This guide compares them on the points that change what a house costs, what you can do with it and what can go wrong. The figures come from official sources: the OMI reference values of Italy's revenue agency, the national seismic classification and ISPRA's flood and landslide data.

First, which region's shore?

The lakes cross regional borders, and the region decides several rules that follow.

• Lake Como (Lario) lies entirely in Lombardy, in the provinces of Como and Lecco.
• Lake Garda is split three ways: the western and south-western shore is Lombardy (province of Brescia), the eastern shore is Veneto (Verona), and the northern tip is Trentino.
• Lake Maggiore has a Lombard eastern shore (province of Varese), a western shore in Piedmont (Stresa, Verbania, Arona) and a northern tip in Switzerland.

So "a house on Lake Garda" can mean Sirmione in Lombardy or Malcesine in Veneto, with different regional rules for lettings and the lakeshore.

Price: the famous lake is not the expensive one

Here are the median OMI reference values for the comuni that touch each lake, Lombard shore only, from the second half of 2025:

• Lake Garda, Brescia shore (14 comuni): €2,475 per m², gross rental yield 3.9%
• Lake Como (43 comuni): €1,350 per m², gross yield 4.6%
• Lake Maggiore, Varese shore (15 comuni): €1,325 per m², gross yield 4.4%

OMI values are the official reference values the Italian state publishes twice a year. They sit below portal asking prices, and nowhere more than on a lake shore, so use them to judge an asking price, not to predict what you will pay.

Two things stand out. Garda's Brescia shore is flat, sunny and built up to the water, so almost every valuation zone is a lake zone. Lake Como is steep: most of its comuni climb far up the mountain behind the villa on the shore, and the comune figure blends the hamlet on the ridge with the road along the water. On Lake Como itself the spread is wide. The lakefront of Como city is valued at €3,550 per m², Cernobbio at €2,325, while Bellagio has no zone above €1,700 and the comuni at the northern end sit around €1,000. At the median, €300,000 buys about 222 m² on Lake Como and about 121 m² on the Brescia shore of Garda. The dearer lake also yields less.

Earthquakes: the lakes split cleanly

Italy assigns a seismic zone to every comune, from Zone 1 (highest hazard) to Zone 4 (lowest). According to the national classification of the Civil Protection Department:

• Lake Como, western (Como) shore: Zone 4.
• Lake Como, Lecco branch: mixed. Lecco, Malgrate, Valmadrera, Abbadia Lariana and Mandello del Lario are Zone 3; Lierna, Varenna, Bellano, Dervio and Colico are Zone 4.
• Lake Maggiore, both shores: Zone 4.
• Lake Garda: Zone 2 on the Lombard shore (13 of 14 comuni; Limone sul Garda is Zone 3) and on the Veneto shore.

Zone 2 does not make a house unsafe, but it raises the stakes of the structural survey on an older building and the cost of works that touch the structure. There is a tax angle too: the Sismabonus relief for anti-seismic works applies only in Zones 1 to 3, so it is not available on the Como side of Lake Como or on Lake Maggiore. Where it does apply, it is a deduction from Italian income tax over ten years, not a grant.

Water and slopes: check the comune, then the parcel

ISPRA, Italy's environmental research institute, publishes for every comune the share of buildings that sit in flood and landslide hazard areas. Some lake comuni stand out (shares of the comune's buildings):

• High flood hazard (the scenario expected every 20 to 50 years): Colico 11.2%, Varenna 10.8%, Domaso 8.7% on Lake Como; Stresa 7.3% on Maggiore. On Garda's southern shore the figure is low: Desenzano and Salò 0.5%.
• Landslide hazard (high and very high classes): Varenna 36.5%, Baveno 27.7% and Stresa 21.5%. Flat southern Garda is close to zero.

These are comune profiles, not a verdict on one house. The official map for a parcel is the river-basin authority's hazard plan, and a geometra (technical surveyor) can pull it before you make an offer. Lakes also rise. In October 2024 Lake Como flooded much of Piazza Cavour in Como. Ask how often the stretch of shore you are looking at has flooded.

The 300-metre rule

Every strip of land within 300 metres of a lake shore is protected landscape by statute, including ground that rises steeply above the water (art. 142 of the Cultural Heritage and Landscape Code, D.Lgs. 42/2004). A new window, a different roof, a pool, a jetty or solar panels need a landscape authorisation (autorizzazione paesaggistica) before any work begins, and the answer is not always yes. The main exception is the historic core: areas already zoned as old town or built-up in the town plan of 1985 fall outside the statutory band.

If you plan to change a lakeside house, find out what the comune and the landscape office will accept before you sign, not after. Our guide to planning compliance explains why the house itself also has to match its permits.

The shore belongs to the state, and so does your jetty

In Italy the shore of a lake is public property, the demanio lacuale. A lakeside owner does not own the jetty, the mooring buoy or the boathouse on it; they hold a concession and pay a yearly fee. In Lombardy the comuni grant these concessions through the lake-basin authorities (Regione Lombardia); in Piedmont and Trentino other bodies do.

A concession is granted to a person, not to a property. When the house is sold, the buyer has to apply to take it over, which usually works but does not have to. A jetty used for decades without any title is a liability, not an asset. Before you sign, ask the seller for the concession document, its expiry date, the last fee receipt and confirmation that it can be transferred to you.

Short lets: registration, not caps

Lombardy regulates short-term lets by registration. Every tourist let needs a regional code, the CIR, and since 1 January 2025 the national code, the CIN, on every advert. We found no lake comune with a cap on private short lets, and in 2025 Italy's Council of State annulled the limits that Sirmione, on Garda, had placed on private landlords (judgment 2928/2025). Rules can change, so check with the comune before you count on rental income. Our guide to the short-term rental tax covers the tax side.

Before you make an offer on a lake house

• Ask for the OMI zone of the address and compare the asking price with it.
• Look up the comune's seismic zone and order a structural survey on an older building, especially on Garda.
• Have a geometra check the parcel on the flood and landslide maps, and ask how high the lake came in 2024 and 2025.
• Check whether the house sits inside the 300-metre band and what has been authorised there.
• Ask for every concession that comes with the house, and for the right to take it over.
• Remember the yearly costs of a second home, including IMU in full; our guide to buying costs in Italy lists every tax and fee.

Where Trovara fits

If you are still choosing a lake, the Trovara Market Report Lombardy (€19) prices all 43 Lake Como comuni one by one, along with the Lombard shores of Garda, Maggiore and Lugano and Lake Iseo, and covers the seismic, flood, landscape and lakeshore rules in depth. It covers the Lombard shores only; Stresa, Verbania and Malcesine are not in it. What you pay for it counts towards your first property report.

Once you have a house in mind, the Trovara Individual Property Report (€109) checks that address: valuation, seismic and hydrogeological exposure, landscape and heritage constraints, and the all-in cost. You can see the format in our sample report.

Prepared with AI assistance and reviewed by the Trovara team. This article is general information, not tax or legal advice. Prices are OMI reference values for the second half of 2025, as published in the Trovara Market Report Lombardy; seismic zones are from the Civil Protection Department; flood and landslide shares are from ISPRA IdroGEO (CC BY 4.0, figures derived by Trovara). Rules checked in October 2026. Always verify with a geometra, a notaio or a lawyer before you sign.
