Regulated rent (canone concordato) in Trieste: how it works in 2026

Regulated rent (canone concordato) is a let with a cap: the rent sits within a range set by Trieste’s local rent agreements, and in return landlord and tenant get tax benefits. In Trieste two agreements are in force today. Here you will find how they work, the zone map, the tables and a free calculator.

Two agreements, both in force

The City of Trieste publishes two local rent agreements and calls both of them in force (page updated on 26 August 2026). The 2022 one was extended by nine of its associations with a protocol of 11 December 2025; the 2025 one, on the other hand, says it replaced it. A lease signed between 15 December 2022 and 15 December 2025 stays on the 2022 agreement until it expires. For a new one, as we read the texts, you choose after comparing the two ranges: one agreement in full, certified by an association that signed it or has adhered to it. No court has ruled on Trieste; our reading also rests on a 2024 judgment of the Regional Administrative Court (TAR) of Lombardy.

Agreement of 15 December 2025

Filed on 15/12/2025; applies to leases signed from 16/12/2025. Tutelati.casa adhered, notified to the City on 13/08/2026 (stated start date: 11/08/2026). The certificate of compliance is issued by one of these associations.

Why there are two agreements, and how you choose →

How it is calculated, in five steps

  1. The zone: in 2025 it comes from the OMI zone of the address (the zones of the Agenzia delle Entrate’s property market observatory), in 2022 from the streets listed in the agreement and its maps. The two zonings do not match.
  2. The weighted floor area: the net floor area of the home (inside, walls excluded), plus balconies, cellar, garage and garden with their coefficients.
  3. The band: in 2025 it is set by a score of 30 features (low, medium, high); in 2022 by a list of features of the home (types A, B and C) that places it in one of three sub-bands.
  4. Increases and reductions: furnishing, APE, term, transitional lease, special value. In 2025 they are added together and applied once only.
  5. The range: floor area times the value per square metre for the zone and band, with the increases. The rent is chosen within it.

The calculator does these steps for you, even if you don’t know everything: it tells you how much, in euros, the missing answers weigh.

The zone map

Type the address or tap the map: you see the zone under the 2025 agreement and the one under the 2022 agreement. The button above the map switches from one agreement to the other.

We find the zone for you, under both agreements. You can also tap the home on the map.

Zone 1 · up to €11.40/m² per monthZone 2 · up to €11.00/m² per monthZone 3 · up to €10.10/m² per monthZone 4 · up to €8.80/m² per month

2025 zones: OMI zones of the Italian Revenue Agency, second half of 2025. 2022 zones: the City’s general map. Addresses © OpenStreetMap contributors. The agreements and the certifying association have the final say.

What landlords and tenants gain

  • Flat-rate tax (cedolare secca) at 10% instead of 21%, unchanged since 2020: it applies to the 3+2, the transitional lease and the student lease, because Trieste is a high housing-pressure municipality.
  • ILIA reduced to 75%: in Friuli Venezia Giulia the property tax is ILIA, not IMU. In Trieste the municipal regulation grants the reduction only to leases with the certificate of compliance, attached to the ILIA declaration: this applies to the 3+2, the transitional lease and the student lease.
  • Under ordinary income tax (IRPEF), on a 3+2 a smaller share of the rent is taxed and the registration tax is calculated on 70% of it (not for transitional leases).
  • The tenant with a 3+2 at regulated rent, if the home is their main home, gets an income-tax (IRPEF) deduction, higher for lower incomes.

Frequently asked questions

Which agreement applies to a new lease in 2026?

The City publishes two, both in force: the 2022 one, extended by nine of its associations, and the 2025 one. As we read the texts, you choose: one agreement in full, and the certificate of compliance from an association that signed it or has adhered to it. The calculator shows you the two ranges side by side; the basis and the risks of the choice are in the article on the two agreements.

How long does a regulated-rent lease last?

The 3+2 lasts at least three years and, unless the parties agree otherwise at expiry, is extended by law for two more. The transitional lease lasts at most 18 months (at least one, under the 2025 agreement), with a temporary need written down and documented. The university student lease runs from 6 months to 3 years.

Who decides the amount of the rent?

The landlord and the tenant, by choosing a value within the agreement’s range for that home: you cannot go above the maximum, nor below the minimum.

Do you need the certificate to get the 10% flat-rate tax?

Yes, if the lease was not signed with the assistance of the landlords’ and tenants’ associations. It is issued by an association that signed the chosen agreement, or one that has adhered to it. Details in the article on the certificate of compliance.

Must a transitional lease in Trieste stay within the agreement’s bands?

Yes: in municipalities with more than 10,000 inhabitants the transitional rent is also calculated with the bands of the local agreement, with its own increase (up to 20% in the 2025 agreement, up to 5% in the 2022 one).

What happens after the first five years?

If nobody gives notice, the lease renews. The rules on renewal, notice and ISTAT updating are in the article on renewal and ISTAT.
