Lottizzazione abusiva: illegal land subdivision in Italy

In Italy, splitting land into plots and selling them is lottizzazione abusiva, an illegal subdivision and a criminal offence, when the features of the plots, such as their size, number, position, the works planned or the profile of the buyers, show unequivocally that they are meant for building against the zoning plan or without permission (DPR 380/2001, Article 30). The buyer of a plot carries real risk: a recorded order from the comune makes deeds on the plots void, after 90 days without withdrawal the land passes to the comune, and a final criminal judgment leads to confiscation.

What Article 30 says

The rule sits in Article 30, paragraph 1, of DPR 380/2001, Italy’s consolidated building code, and covers two different situations. In the first, works begin that transform land in planning or building terms against the zoning instruments in force or adopted, against national or regional law, or without the required permission. Think of a new access track or foundations being dug on farmland.

The second concerns splitting the field into new cadastral parcels (frazionamento) and selling them. Land is also illegally subdivided when the transformation is «prepared through the subdivision and sale, or equivalent deeds, of the land in plots» whose features «show unequivocally» that they are meant for building. Lawyers and judges call the first a material subdivision (lottizzazione materiale) and the second a paper subdivision (lottizzazione cartolare). The statute does not use those labels, but it describes both cases.

The paragraph also gives examples («quali», such as) of the plot features to look at: size against the nature of the land and its use under the plan, the number of plots, where they lie, any planned infrastructure such as roads and utilities, and facts about the buyers. What the law requires is that the features of the plots show «unequivocally» that they are meant for building; whether they do in a given case is for the comune and the courts to assess. The diagram below places these elements on an imaginary field.

Warning signs on a plot for sale

A buyer usually looks only at the plot on offer. The warning signs often sit in the field it was carved out of, and they can be read in public records. The table turns the criteria in paragraph 1 into practical questions. It is a reading aid, not a list set out in the law.

An advert selling «plots» of farmland «with room for a cabin» is a sign not to ignore: the seller is the one talking about building. A visura is an extract from the cadastral database; a map extract (estratto di mappa) shows the parcel with its neighbours. To tell this apart from an ordinary split of a field, see the guide on buying part of a plot.

What the buyer of a plot risks

The consequences run on two tracks, one administrative and led by the comune (the municipality), the other criminal. Both concern the land, whoever owns it when they arrive.

The comune’s track. When the head of the relevant municipal office finds a subdivision without the required permission, he or she orders it suspended. The order is served on the owners of the land and on the others answerable under Article 29: the permit holder, the client and the builder. It halts work at once, bans any transfer of the land and buildings between living persons, and must be recorded (trascritto) in the property registers (Article 30, paragraph 7).

Once recorded, deeds on those plots are void and cannot be signed, whether before a notary or privately, until the order is cancelled or lapses (paragraph 9). If the order is not withdrawn within 90 days, the subdivided land passes by law into the comune’s disposable assets, and the comune must demolish the works (paragraph 8).

The criminal track. An illegal subdivision is punished with imprisonment of up to two years and a fine of 30,986 to 103,290 euros. The sentence is arresto, the custodial penalty Italian law provides for the class of offences called contravvenzioni (Criminal Code, Article 17). The fine is the 15,493 to 51,645 euros written in Article 44, paragraph 1, letter c, doubled by Decree-Law 269/2003, which provided that the fines in Article 44 are «increased by one hundred per cent» (Article 32, paragraph 47). A final judgment that finds the subdivision orders confiscation of the subdivided land and the buildings on it: the land passes to the comune free of charge, and the judgment is entered in the property registers at once (Article 44, paragraph 2).

The zoning certificate in the deed

Paragraph 2 of Article 30 is the rule the notary applies to sales of land. A deed is void, and can be neither signed nor recorded, unless the certificato di destinazione urbanistica (CDU), the comune’s certificate of the planning rules for the land, is attached. The exception is land that forms the grounds of a building registered in the buildings cadastre, provided those grounds cover less than 5,000 m².

The comune must issue the CDU within 30 days of the request, a binding deadline. It stays valid for a year if the seller declares that the plan has not changed (paragraph 3). If the comune misses the deadline, the CDU can be replaced by a declaration from the seller, or one of the co-owners dividing the land, stating that the request was made and giving the land’s planning use under the plans in force or adopted, or that no such plans exist, or that the approved general plan requires detailed implementing plans (paragraph 4). Agree its wording with the notary. A deed signed without a CDU can be confirmed later, even by one party alone, by a notarial or authenticated deed with a certificate attached that refers to the date of the original deed (paragraph 4-bis).

The CDU tells you what the plan allows on that land. It does not tell you whether the field has already been divided and sold in plots, or whether proceedings are open: a perfectly valid CDU can sit alongside a subdivision under way. How to read one is explained in the guide to the CDU.

When Article 30 does not apply

Paragraph 10 sets a time limit and a list of exclusions. The article’s provisions apply to deeds signed and subdivisions filed with the cadastre after 17 March 1985. In any case they do not apply to:

• divisions between heirs, and wills;
• gifts between spouses and between relatives in the direct line, such as parent and child;
• deeds that create, change or end security rights, such as a mortgage, or easements.

The list covers those deeds, not what happens next. A division between heirs or a gift to a son stays outside, but later sales to strangers are not on the list. If the history of a field shows a division between heirs followed by sales of pieces to outsiders, have the notary assess the whole sequence.

An illegal subdivision concerns the land. If a house already stands on the plot, Article 46 applies as well: deeds on buildings begun after 17 March 1985 are void unless the seller states the details of the building permit or of the permit issued in regularisation. How to spot unauthorised work on the building itself is covered in the guide to unauthorised building work.

How to check before the preliminary contract

Do these checks before you sign any commitment, including the preliminary contract (compromesso), because once an order is recorded no deed on the plot can be signed. The comune has up to 30 days to issue the CDU, so request it first.

1. The map around the plot (online, same day). Order the map extract centred on the parcel and look at the parcels around it: shape, size, numbering. Narrow, regular parcels in a row with consecutive numbers may point to a recent split. The Agenzia delle Entrate, which runs the cadastre, issues the extract free of charge as a PDF, including for parcels owned by others; the steps are in the guide to the cadastral map extract.
2. The history of the original parcel (online, same day). A historical visura, also available online from the Agenzia delle Entrate, shows which parcel the plot came from, when it was split and how many parcels were created. If the seller has already sold other pieces, the owners’ names show it. The guide to the historical visura explains how to read it.
3. The property registers (online or at the counter). A search of the property registers (ispezione ipotecaria) on the seller and earlier owners shows whether a suspension order or a confiscation judgment has been recorded. The procedure is in the guide to the ispezione ipotecaria.
4. The comune’s planning office (timing depends on the comune, so ask early). Ask in writing, quoting sheet (foglio) and parcel (particella), whether any proceedings for illegal subdivision concern the field, and whether an approved subdivision plan (piano di lottizzazione) authorises the split.
5. The CDU (up to 30 days). The seller or your technician requests it from the comune; the comune charges a secretarial fee on it within a minimum and maximum set by law (Decree-Law 8/1993, Article 10, paragraph 10), and the issuing office will tell you the amount.
6. The notary (before the preliminary contract). Hand over everything: map, visure, register search, the comune’s reply and the listing. The notary judges whether what you have gathered points to a risk and whether the deed can be signed.

The TerrenoCheck report helps with the first step: it shows the parcel together with its neighbours found in the cadastral data, as in the example below.
