Cost of renovating a house in Italy: budget, bonus and how to estimate

The cost of renovating a house in Italy has no single answer, and anyone who gives one in a line, as a price per square metre, is simplifying more than a budget can afford. What a renovation costs depends on what is found behind the plaster, on what you decide to change, on the finishes, on legal constraints and on how the site is organised. A serious estimate can still be built, item by item, and the quotations that arrive can be read with method.

This guide explains how to reason about the cost of renovating a house in Italy: which items make up the budget, which public references exist for unit prices, what a turnkey contract changes and how the tax deductions now in force work. It is written by Federico Cappellina Architects, an architecture practice in Verona that designs residential projects in north-east Italy and Lombardy and supervises their construction, for owners and buyers who do not know the Italian system. We do not publish a price list: the figures quoted come from public sources named in the text and are references, not quotations. Nothing here is legal or tax advice.

Cost of renovating a house in Italy in brief

There is no reliable single figure for the cost of renovating a house in Italy per square metre. Popular averages mix works that have nothing in common.
The real number comes from a measured list of works (in Italian, computo metrico estimativo): quantities taken from the design and priced. See our guide to the bill of quantities in Italy.
The cost of renovating a house in Italy has five parts: works, technical fees, permits and charges, furnishings, and a reserve for the unexpected.
The regional price list is a public reference for unit prices (Veneto 2026: DGR 486 of 9 June 2026); it does not say what a private contractor will charge.
Tax relief exists but changes with every budget law: for expenses in 2025 and 2026 the Agenzia delle Entrate gives 50% or 36%, with a cap of 96,000 euros.
A turnkey price is worth what the contract lists. Independent site supervision protects the owner in every contract form.

Cost of renovating a house in Italy per square metre: what the averages say

Consumer-finance and property websites publish averages per square metre. One example is an article on money.it from May 2025, which gives an average of between 400 and 850 euros per square metre for a renovation and observes that for high-level renovations the figure can exceed 1,000 euros, with no ceiling. Other sources give narrower or wider ranges, and none reliably tells a house in Veneto from one in another region.

The difficulty is that such an average holds together jobs with nothing in common: repainting and a complete replacement of services, windows and floors; a flat of one hundred square metres and a villa with a swimming pool; a catalogue finish and a detail drawn specially for the house. For a villa, the cost per square metre is almost always the result of a sum, not the starting point. We therefore start from the survey and the design and arrive at the figure through the bill of quantities.

If you come from a market where rules of thumb per square metre or per square foot are common, treat them as a first orientation and nothing more. The cost of renovating a house in Italy is settled by the list of works, not by the floor area on the title deed.

What drives the cost of renovating a house in Italy

The variables that weigh most on the cost of renovating a house in Italy are always the same. Knowing them explains why two quotations can differ greatly even for the same property.

The condition of the building. Electrical and plumbing systems to be redone, rising damp, floors or roofs to be strengthened, windows to be replaced. What cannot be seen before the walls are opened is the first source of surprises.
The extent of the intervention. A job that touches structures, layout, façades and services involves more trades, and more coordination, than a renewal of finishes.
The performance required. Insulation, heating and cooling, high-performance windows, home automation and acoustics cost more than basic solutions.
Finishes and details. Floors, wall coverings, sanitary ware, doors, lighting: in many budgets the most elastic part, and the one where the final cost is really decided.
Constraints. A listed or landscape-protected property needs extra authorisations and time, and may impose materials and techniques.
The site. Difficult access, tight spaces, works in an occupied house, the season and the availability of contractors.
Time. A longer site costs more, through equipment hire, site supervision and the inconvenience to the owner.

The five parts of the cost of renovating a house in Italy

A complete budget is not the same thing as the contractor’s quotation. To avoid underestimating the cost of renovating a house in Italy, break it into five groups of expenditure.

1. The works

The building and services works carried out by contractors: demolition and disposal, masonry and plaster, screeds and waterproofing, electrical, plumbing, heating and cooling systems, windows and doors, floors and wall coverings, metalwork and joinery, painting. They are estimated with the bill of quantities (computo metrico estimativo): a list of work items with measured quantities and unit prices.

2. The technical fees

Survey, design, the building application, specialist reports (structures, services, energy), site supervision and safety coordination. How the fee is calculated is explained in our guide to architect fees for a villa in Italy.

3. Permits and charges

The building permit or notice that applies to the works, and the fees due to the Comune (the municipality). Where the renovation is among those that carry a charge, the construction contribution (contributo di costruzione) of Article 16 of D.P.R. 380/2001 comes into play; for renovation the municipality may set values lower than those for new buildings. Which notice is required is the subject of our guide to CILA and SCIA.

4. Furnishings and supplies bought by the owner

Kitchen, bathrooms, decorative lighting, curtains, furniture: if they are not in the contract with the contractor they belong in a separate budget line, because they change the result as much as the building works do.

5. The reserve for the unexpected

A share of the budget should stay unallocated, set with the designer according to the age and condition of the building. A house from the 1960s with original services does not carry the same margin of uncertainty as one built after 2000.

How to estimate the cost of renovating a house in Italy in six steps

A serious estimate of the cost of renovating a house in Italy is a sequence, and the order matters.

Inspection and survey. Measurements, condition of the services, levels, visible structures, any cracks or damp. An approximate survey produces an approximate bill of quantities.
Brief and priorities. What you want to achieve, what is not to be touched, what can wait.
Design. Plans, elevations, sections and details. With the design you know what is being built, and the cost stops being a figure per square metre. Our guide to the house design process in Italy describes the phases.
Bill of quantities. Quantities are measured from the design and priced with unit prices, for which a public reference is the regional price list discussed below.
Specification and request for quotations. The same items, quantities and materials go to several contractors, so that their offers can be compared. The document that describes how the work is done is the construction specification (capitolato).
Contract and site supervision. The cost is controlled during the works, through progress statements and variations approved in writing by the site manager (direttore dei lavori) on the owner’s behalf.

The regional price list: a public reference for the cost of renovating a house in Italy

To judge whether the cost of renovating a house in Italy is consistent item by item, designers use the price lists (prezzari) published by the Italian regions. In Veneto the price list is published by the Regione: the 2026 edition was approved by regional resolution DGR no. 486 of 9 June 2026 and has been in force since 1 July 2026. It can be consulted online on the regional price list website and comprises the list of prices, the price analysis, the parametric costs and the measurement rules, also in open file formats.

It is a reference list born for public works. It does not say what a private contractor will ask for your site, but it lets you check whether an item is very far from the reference unit prices, and understand which costs are included in a work item (materials, labour, equipment hire, general expenses). A quotation below these values needs an explanation; so does one far above them. Other regions publish their own price lists, and the relevant one is that of the place where the house stands. How a measured list is read is explained in our guide to the bill of quantities in Italy.

Turnkey renovation (chiavi in mano) and the cost of renovating a house in Italy

With a turnkey formula (chiavi in mano, literally “keys in hand”) a single party, usually a general contractor or a company coordinating several trades, undertakes to deliver the complete work for a defined price and time. It reduces the number of people the owner deals with and can give more certainty on the final figure. It must still be read carefully, because the price is worth what the contract lists.

What is included. Building works, services, finishes, disposal, permits? A turnkey offer without a detailed specification leaves room for “excluded” works that become extras.
Who checks the execution. If the person who designs, builds and checks is the same, the owner has no independent control. Site supervision entrusted to an independent professional protects the owner in a turnkey contract too.
How variations are handled. They must be approved with a written quotation, item by item.
Time and penalties. A contractual programme and the consequences of delay.

Whatever the contract form, quotations can be compared only if they describe the same work: the same quantities, materials and excluded items (disposal, scaffolding, permits and making good are often outside the price), and the same conditions. An unpriced bill of quantities, which each contractor fills in on the same list, is the simplest way to obtain offers that can be compared.

We design and supervise the works; execution belongs to the contractor chosen by the owner, and the bill of quantities lets us compare offers on equal terms. A turnkey price changes how the cost of renovating a house in Italy is organised, not how it is verified.

Tax deductions that reduce the cost of renovating a house in Italy

Part of the cost of renovating a house in Italy can be recovered through the tax deduction for building renovation (recupero del patrimonio edilizio), which Italian media and websites often call a “bonus”. According to the Agenzia delle Entrate page on the amount of the deduction and its limits, for expenses incurred in 2025 and 2026 the deduction is 50% for the main home of an owner or holder of a real right of enjoyment (diritto reale di godimento), and 36% in the other permitted cases, with a maximum eligible expense of 96,000 euros. For 2027 the percentages fall to 36% and 30%, with the same limit; from 2028 to 2033 a rate of 30% applies to all dwellings in the permitted cases, with a limit of 48,000 euros, and from 2034 the rate is 36%.

The deduction is a tax recovery spread over the years, not an immediate discount on the invoice, and it depends on precise requirements: the nature of the works, the building title, the way payments are made and the documentation. The rules change with the budget laws, so before basing a budget on the deduction read the current page of the Agenzia and speak to an accountant (commercialista); the page itself carries no explicit date and refers to circulars of 2025. Whether it is useful to you also depends on your own tax position in Italy, which a non-resident owner should check first. For our part, we deal with the technical side: the correct building application and the documentation of the works.

Mistakes that inflate the cost of renovating a house in Italy

Most overruns in the cost of renovating a house in Italy come from a few repeated mistakes.

Starting work without a design. Decisions taken during the works cost more than decisions taken on paper.
Changing your mind during the works. Every variation means work to be removed and new prices to be agreed.
Choosing the lowest quotation without reading it. Missing items reappear later as extras.
Underestimating the services. The least visible part and, if redone during the works, the one that weighs most.
Having no reserve. A budget with no margin breaks at the first surprise.

Three scenarios for the cost of renovating a house in Italy

We give no figures, because they depend on the property, but we can show where the cost of renovating a house in Italy moves from one kind of intervention to another. They are examples of reasoning, not quotations.

Renewal of finishes

Paint, floors, doors, bathrooms left where they are. The main items are finishes and supplies, the building application is light (often ordinary maintenance or a CILA, the notification of works signed by a qualified technician) and surprises are few, because structures are not opened. The budget depends above all on the choice of materials.

New services and a new internal layout

New systems, bathrooms and kitchen moved, partitions demolished and rebuilt, new windows. Work runs in sequence, so one contractor’s delay reflects on the others. The bill of quantities becomes indispensable, and the reserve for the unexpected has to be sized with care, because existing services are known only by opening the walls. The building title depends on what is touched, as our guide to CILA and SCIA explains.

Deep renovation with structural changes

New openings in load-bearing walls, strengthening, rebuilt floors or roofs, changes to elevations, an improved thermal envelope. To the works are added structural and energy reports, heavier applications, longer times and, in some cases, the construction contribution. It is also the case in which to weigh renovation against demolition and rebuilding, as our guide to demolishing and rebuilding a house in Italy explains; the heavier title is covered in our guide to the building permit in Italy.

Controlling the cost of renovating a house in Italy during the works

A site that runs long costs money even when contractors ask for nothing more: supervision requires more visits, a house you live in stays out of use, and a substitute rent keeps running. Time is therefore designed like everything else: a programme that orders the work, allows for materials with long delivery times and shows the dates by which the owner must decide. Postponed decisions are the first cause of delay and of cost.

The designer’s work on the cost of renovating a house in Italy does not end with the first estimate. In chronological order:

first, feasibility is checked with a parametric budget, to avoid developing a design that is out of scale;
during design, choices are steered towards solutions that fit the budget, showing the cost of the alternatives;
at tender stage, the bill of quantities and specification are prepared and the offers are compared;
on site, quantities are checked and variations are approved in writing with their price;
at the end, the accounts are closed and the documents are handed over, including those needed for the certificate of habitability.

The client therefore always knows what is being paid for and why, which is the reason we consider site supervision part of the design and not an additional service.

The cost of renovating a house in Italy if you live abroad

Many owners manage a renovation at a distance, and the Italian system allows it if a few things are settled at the outset. Ask for the bill of quantities and the specification in a form you can read. Require every variation to be priced and approved in writing before it is carried out. Make sure that payments follow progress statements and not arbitrary dates. Entrust the checking of quantities and quality to a professional who answers to you and not to the contractor. And before counting on any tax deduction, ask an accountant whether it applies to your situation.

These points matter more at a distance, because you cannot see the site every week. Without a survey, a design and a measured list of works, the cost of renovating a house in Italy remains a guess, and a guess is hard to manage from another country. If the renovation is part of a purchase, our guides to buying land in Italy and to the questions to ask an architect cover the checks that come before the budget.

Cost of renovating a house in Italy: frequently asked questions

What is the cost of renovating a house in Italy per square metre?

The cost of renovating a house in Italy depends on the condition of the property, the extent of the works and the finishes. Popular estimates vary widely (one source gives 400 to 850 euros per square metre as an average and more than 1,000 euros for high-level work) and do not replace a bill of quantities prepared on the design.

What does a turnkey renovation mean, and how does it change the cost of renovating a house in Italy?

A single party delivers the complete work for a contractual price and time. It is worth checking what the contract includes, who checks the execution and how variations are handled.

Which tax deductions apply to the cost of renovating a house in Italy?

According to the Agenzia delle Entrate: 50% for the main home and 36% in the other permitted cases for expenses in 2025 and 2026, with a limit of 96,000 euros; 36% and 30% for 2027; from 2028 to 2033, 30% with a limit of 48,000 euros. The rules change with the budget laws.

How does the regional price list help check the cost of renovating a house in Italy?

It is the reference list of unit prices for building work, published by each region. The Veneto list for 2026 was approved by DGR 486 of 9 June 2026 and has been in force since 1 July 2026.

Do I need an architect to control the cost of renovating a house in Italy?

For many interventions the building title requires a qualified technician to sign the application, and a good design and bill of quantities reduce surprises. Involvement ranges from the application alone to a full design with site supervision.

How long does a renovation take, and does time change the cost of renovating a house in Italy?

It depends on the scope, the constraints and the availability of contractors, and it should be fixed in the contract with a programme. A longer site costs more, even when contractors ask for nothing extra.

Is the cost of renovating a house in Italy the same as the contractor’s quotation?

No. The quotation covers the works; the budget also includes technical fees, permits and charges, furnishings supplied by the owner and a reserve for the unexpected.
