Regulated rent (canone concordato) calculator for Trieste
How much can you ask, or how much should you pay?
Answer what you know, skip what you don’t: the range appears as soon as you say how big the home is, and narrows as you answer. We calculate together the two agreements that the City of Trieste publishes as in force, the 2025 one and the extended 2022 one: the two ranges sit side by side, and we tell you which gives more.

- A figure as soon as you say how big the home is
- We tell you what we don’t know, and how much it weighs
Is the lease still to be made, or is there one already?
In Trieste two local rent agreements are in force, as the City states: the one of 15 December 2025 and the one of 14 December 2022, extended by its signatories. For a new lease you choose: we show you both, and the lease follows the one you choose in full.
Where is the home?
The address decides the zone. Type it in, or tap the map where the home is.
We find the zone for you, under both agreements. You can also tap the home on the map.
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.
How big is it?
The agreement counts the net floor area: the space inside the home, without the walls, balconies or cellar. If you haven’t measured it, that’s fine: tell us where your square metres come from and we’ll do the conversion.
Where do your square metres come from?
There is also…
These count too, at a percentage. The garage and parking spaces only if you let them together with the home.
Balconies or terraces
Cellar or loft
Garage
Covered parking space
Open-air parking space
Garden or courtyard for your use only
Shared garden with lawn
What is the home like?
Each feature is worth points (Annex 1 of the 2025 agreement): the points decide the band, low, medium or high. For the 2022 agreement the same answers decide the sub-band. Answer what you know; “don’t know” is perfectly fine.
What is the heating like?
Do you have the certificates of conformity (dichiarazioni di conformità) for all the systems?
Fixed air conditioners in at least half the rooms?
Double glazing on at least half the windows?
Reinforced door, window bars or alarm?
Video entryphone?
Photovoltaic panels, or solar panels for hot water?
Any home automation?
Energy and furnishing
Do you have the APE, the energy performance certificate?
Will you let it furnished?
Does the kitchen have an oven, a hob and a fridge?
Which lease do you want to make?
It changes the cap: we show you all of them, choose which one to highlight.

How the calculation works
Regulated rent has a cap and a floor, set by the City’s local rent agreements. The calculator follows their steps: the zone from the address, the weighted floor area (net floor area plus balconies, cellar and parking spaces with their coefficients), the band from the features of the home, and the increases for furnishing, APE, term and type of lease.
The sums are done by the same engine we use in the agency to prepare leases, tested against cases calculated by hand. The result is shown in €100 brackets: the figure to the cent depends on measurements and documents that are best looked at together.
Two agreements, two ranges
In Trieste the City publishes two agreements in force: the one of 14 December 2022, extended by nine of its associations on 11 December 2025, and the one of 15 December 2025. We calculate them together and show you the two ranges side by side, marking the one that gives the higher cap for your home. For a new lease, as we read the texts, you choose: you tap the range of the chosen agreement, the lease follows it in full and the certificate is issued by an association that signed it or has adhered to it. A lease signed between 15 December 2022 and 15 December 2025 stays on the 2022 agreement until it expires. We explain this in 2022 or 2025?.
If you don’t know the floor area, the APE or the zone
Almost every question has a “don’t know” answer; for the floor area it is enough to know how many rooms the home has. For each doubt we keep all the possibilities open and calculate the lowest and the highest cap: the real range lies in between. Then we tell you, in euros, which missing answers weigh most, so you know what is worth checking first.
If you have the square metres from the cadastral extract, the APE or a listing, we convert them into net floor area with a stated margin. If you only know how many rooms the home has, the estimate is wider. If you type the address, we look up a nearby stop, food shop or pharmacy and park on OpenStreetMap and suggest the answers: you can always change them.
After the calculation
To get the 10% flat-rate tax (cedolare secca) and the other benefits, a lease made without the assistance of the associations needs the certificate of compliance (attestazione di rispondenza). You can prepare the lease with our generator, or make it with us.
You can print the summary, and save the estimate in your area with a free account. And if you would rather talk it through with a person, there is “We’ll call you back”: choose the days and times, and we contact you by phone or email.
Frequently asked questions
Is the result valid as a certificate of compliance?
No. It is an estimate to help you get your bearings: the certificate is issued by an association that signed the agreement applied or has adhered to it, on the basis of the lease details.
Which floor area should I enter?
The net internal floor area: the floor of the rooms, without walls, balconies, cellar and unregistered mezzanines. If you only have the square metres from the cadastral extract, the APE or a listing, choose where they come from: we do the conversion.
What if the home is on the boundary between two zones?
Under the 2025 agreement, on the boundary or where in doubt, the zone with the higher value applies. If the address falls on the boundary we use that zone; if it is close to one, we tell you.
With 13 or 19 points, which band am I in?
The 2025 agreement contradicts itself: article 7 and the note to Annex 2 do not match. We show the cap for both bands; which one applies is decided by whoever issues the certificate of compliance.
Can I have a regulated-rent lease without an APE?
You need an APE to let a home in any case. Without a valid class we cannot tell whether the energy increase or the reduction applies: we consider all the possible classes, from G (minus 10%) to A (plus 12%).
Are the 2022 tables updated for ISTAT inflation?
The 2022 agreement allows them to be updated every year for new leases, and one of its signatories, Confappi, publishes the October 2025 tables. The lower cap uses the original table, the higher one the updated table.
Data used: local rent agreement of 15/12/2025 and agreement of 14/12/2022 (with the protocol of 11/12/2025 and the tables updated for ISTAT inflation in October 2025); OMI zones of the Agenzia delle Entrate, 2nd half of 2025; the City of Trieste’s 2022 zone maps; addresses, stops, food shops, pharmacies and parks from OpenStreetMap. Checked on 26/10/2026.
