Property valuation in Trieste: what it's worth, by zone (2026)

In Trieste, in the first half of 2026, a standard home (abitazione civile) in normal condition was worth between €1,650 and €3,100 per square metre, depending on the zone. The figures come from the OMI (Osservatorio del mercato immobiliare), an observatory within the Italian Revenue Agency (Agenzia delle Entrate). With your zone and the right floor area, you can work out your home's range in ten minutes; the floor, the light, the condition and the paperwork then narrow it down.

At a glance

• The basis: the OMI values, revised every six months, with three quarters of their data taken from sale deeds.
• The floor area: the cadastral extract (visura catastale) already gives the area measured the way the OMI wants it (gross, balconies at 30%).
• The sum: the square metres times the minimum and the maximum for your zone. That is the range for an ordinary home.
• Over twelve months the midpoint of the range rose in all 11 zones: from 10% in San Vito to 19% in the urban centre.
• The asking price is not the price signed: in north-east Italy, sales close on average 5% below the asking price; across Italy, selling takes about five months (Bank of Italy).

OMI values in Trieste, zone by zone

The OMI divides the municipality into 11 zones and publishes a minimum and a maximum per square metre for each. These are the values for standard homes in normal condition, meaning the condition most often found in that zone:

OMI zone	Neighbourhoods	Sale, €/m²	Rent, €/m² per month
B2	Historic centre	2,500–3,100	8.5–12.1
B1	Urban centre	1,800–2,300	6.7–9.2
C1	San Vito	1,950–2,600	7.4–10.5
C2	San Giacomo, Chiarbola, Servola, Monte San Pantaleone	1,650–2,150	5.3–7.7
C3	Cologna, Roiano, part of Gretta	1,750–2,300	6.5–9.5
C4	Chiadino, Guardiella, San Giovanni, Rozzol	1,750–2,450	6.7–9.6
C5	Scorcola	2,100–2,750	7.0–9.6
D1	Southern outskirts, Altura, San Sergio, Santa Maria Maddalena	1,700–2,050	5.8–7.4
D2	Opicina	1,800–2,500	6.3–8.9
D3	Part of Gretta, Barcola, the Costiera	2,150–3,100	8.0–12.0
R1	Villages on the Karst plateau	1,750–2,250	6.2–9.1

How to read it:

• The right row. For its statistics the OMI pairs standard homes with cadastral categories A/2 and A/3, and "economy-type" homes (tipo economico) with A/4, A/5 and A/6. Economy-type homes sit lower: in San Giacomo and Servola, €1,250–1,600 per m². Villas and detached houses (ville e villini) have rows of their own: in Barcola and along the Costiera, €2,100–3,100 per m².
• The right boundary. OMI zones do not line up with the rioni, the neighbourhoods people name in everyday conversation. You can find yours on the Agency's map (GEOPOI, free to use) by searching for the address.
• What is left out. The minimum and maximum describe the ordinary homes in the zone. The OMI deliberately excludes properties of exceptional quality or in very poor repair: the penthouse with a terrace over the gulf and the house that needs gutting fall outside the range.

The right floor area: take it from the cadastral extract

The OMI range only works with floor area measured the OMI way: gross, including internal walls and outer walls up to 50 cm thick, plus half of any walls shared with the neighbours. Balconies and terraces you can step out onto from the home count at 30% up to 25 m² and at 10% beyond that; cellars and attics at 50% if they connect with the home, 25% if they don't.

You don't have to calculate this yourself. Since 9 November 2015 the cadastral extract has shown the area calculated under Presidential Decree (DPR) 138/1998, whose rules the OMI has adopted. Owners can download it free of charge from the Agenzia delle Entrate's online services; the figure is missing only when the cadastre holds no usable floor plan (planimetria). You will see two numbers: the total area, and the area "excluding uncovered areas" (escluse aree scoperte), which leaves out balconies and terraces. For the sum you need the first.

Two traps that are typical of Trieste:

• Local custom measures something else. For sales "by measurement" (a misura), the Trieste collection of trade usages (Raccolta degli usi, art. 50) counts the area from the inner face of the façade walls, without their thickness; balconies and terraces count at 50% up to 5 m² and 33% above that, glazed-in ones at 70%. In period buildings, where façade walls are thick, the gap with gross area is noticeable. OMI values only with OMI square metres.
• A veranda counts only if it is authorised. A veranda closed in without planning permission adds no value: it is a problem to sort out before the final deed (rogito) (cadastral and planning compliance).

The same collection says that in Trieste a flat, with its garage, cellar and attic, is "generally" sold as a whole (a corpo): the price is for that home, not per square metre. Under the Civil Code (art. 1538), a difference in size moves the price only when the real measurement differs by one twentieth, 5%, from the one written in the contract.

A worked example

Example: a flat in San Vito (zone C1), category A/2, on the third floor with a lift, in normal condition. The cadastral extract gives 92 m² of total area, balcony included. In the same building there is a 14 m² garage.

Step	Calculation	Result
The home's range	92 m² × €1,950 and × €2,600/m²	€179,400–239,200
Midpoint of the range	92 m² × €2,275/m²	€209,300
The garage (C1: €2,100–2,900/m²)	14 m² × €2,100 and × €2,900/m²	€29,400–40,600
Rent, for comparison	92 m² × €7.4 and × €10.5	€681–966 a month

In San Vito a garage is worth more per square metre than the flat: €2,100–2,900 per m² against €1,950–2,600.

Next you move the point within the range. Here the third floor with a lift and a glimpse of the sea push it up; the bathroom that needs redoing and energy class G push it down. A reasonable estimate lands in the upper half, not at the top: €2,350–2,450 per m², or €216,000–225,000, garage not included.

If the aim is to close at €220,000, asking around €230,000 leaves the margin the market expects. Asking €260,000 usually means cutting the price after weeks of few viewings.

The rent in the example, taken at the middle of the range, would yield about 4.7% a year on the value. That is a gross yield: tax, running costs and empty months bring it down.

What moves your home within the range, and out of it

The OMI says so itself: within the same zone, value changes with the floor, the outlook, the orientation and the quality of the surroundings, none of which the values can see. In Trieste these weigh most:

1. Floor and lift. Many period buildings in the centre have no lift: a fourth floor reached on foot appeals to fewer buyers than a second.
2. Light and orientation. In a city built on a hillside, two flats in the same building can face opposite ways.
3. The view. A glimpse is not half a view; a full view over the gulf often takes a home outside the range.
4. Condition. A home that needs renovating loses more than the cost of the works: buyers also price in time, permits and surprises.
5. Energy class. It has to appear in the listing, and it weighs on the buyer's bills (the APE and energy class).
6. The building. High service charges, or major works the owners have already approved, get knocked off in the negotiation.
7. The paperwork. A floor plan that doesn't match, a veranda without permission, a transfer of ownership never entered in the land register (Libro fondiario): they do more than lower the price, they can stop the deed (the documents you need to sell).

Why an online valuation gets yours wrong

Property portal calculators basically do the sum from the table: a zone average times the square metres you type in. For the order of magnitude, that is fine. But they often start from asking prices in listings, and they cannot see what moves the price: floor, light, view, condition, building, paperwork.

The OMI comes out only twice a year, but it looks at completed sales: in 2024 about 75% of its data on sales came from deeds and 20% from offers. In September 2026 the average asking price on idealista in Trieste was €2,673 per m², above the midpoint of the OMI range in 10 zones out of 11.

Then there is a second valuer the seller doesn't get to choose: the buyer's bank. In the second quarter of 2026, 63% of purchases went through with a mortgage, and the average loan covered 78% of the home's value (Bank of Italy). The value is set by the bank's valuer: if the price is higher, the buyer pays the difference out of pocket, or the negotiation stalls (the mortgage with the real monthly payment).

Frequently asked questions

How much is my house worth in Trieste?

The OMI gives you the range: the square metres on your cadastral extract times the minimum and the maximum for your zone. Where you fall within it depends on floor, light, view, condition and paperwork, and only someone who sees the home and compares it with nearby sales can tell you.

Is an online property valuation reliable?

For the order of magnitude, yes. For setting the price, no: it doesn't see your home, and it often starts from listings rather than sales.

Is the cadastral value what my home is worth?

No. The cadastral value (valore catastale) is the cadastral income (rendita catastale) increased by 5% and multiplied by 110 if the buyer qualifies for first-home relief (prima casa), or by 120 for other homes. With a cadastral income of €800, that gives €92,400 or €100,800. It is used to work out the taxes on the purchase, not the price (the buyer's taxes).

How often are OMI values updated?

Every half-year, a few months after the period ends. We read the values in this guide (first half of 2026) in October 2026, and we update the guide when the next half-year comes out.

Do I need a formal valuation to sell my home?

To set the price, usually not: a well-made comparison with similar sales is enough. A valuation report (perizia) signed by a surveyor is needed when the value has to stand up in front of others, for example when heirs divide an estate or in a court case.

What to do now

• Download the cadastral extract from the Agenzia delle Entrate's online services and note the total area and the category.
• Find the zone on the OMI's GEOPOI map and do the sum: square metres times the minimum, square metres times the maximum.
• Write down, honestly, what moves your home up or down: floor, lift, light, view, condition, energy class, service charges.
• Check the paperwork before you set the price: a floor plan that matches, an authorised veranda, registration in the Libro fondiario.
• Put the costs next to the price: what selling a home costs.

What this guide doesn't tell you

It doesn't tell you what your home is worth: it gives you the range for an ordinary home in your zone and a way to reason about it. OMI values, as the Agency itself states, are no substitute for valuing an individual property. For a value that stands up in front of others you need a surveyor; for the taxes on the sale, the notary and an accountant (commercialista).

If you sell with us. We read the paperwork first, then come to see the home and give you a price range with the reasoning behind it, built on similar homes in the zone and on the Agenzia delle Entrate's values, as in this guide. No commitment. Tell us about your home.
