Buying a house in Italy: verifying the urban planning compliance and the risks of unauthorized construction

Buying a house in Italy and verifying the urban planning compliance: understanding building violations, illegal construction, and securing your investment.

Buying a house in Italy and verifying the urban planning compliance

Buying a house in Italy requires verifying its urban planning compliance before any acquisition. This step is essential to avoid risks associated with unauthorized alterations, illegal construction, or breaches of town planning regulations.

A property may appear compliant at first glance, while still having significant irregularities under Italian law.

"Abuso edilizio" in Italy: definition and legal risks

Under Italian law, an abuso edilizio refers to any work carried out on a property without authorization or in breach of a building permit.

This includes new constructions, as well as unauthorized internal modifications or extensions.

A situation involving an illegal building work can lead to significant consequences. Local authorities may order the demolition of non-compliant parts, impose administrative fines, or prevent the sale of the property.

In some cases, an illegal construction also prevents the buyer from securing mortgage funding or carrying out future renovations.

Types of Non-Compliance with Italian Urban Planning Regulations   

Italian law distinguishes between several types of urban planning violations.

Total non-compliance (abuso totale) refers to a property built without any building permit. This is the most severe violation and is often difficult to regularize.

Partial non-compliance (abuso parziale) involves works carried out partially without authorization or not in accordance with the issued permit. This may include extensions, volumetric modifications, or changes of intended use.

Minor irregularities may also exist, such as discrepancies between the cadastral plans and the actual state of the property.

Each situation must be analyzed on a case-by-case basis to assess the risks and options for regularization.

Regularizing unauthorized construction and planning permits in Italy

In certain cases, a building violation (abuso edilizio) can be regularized.

The regularization depends on several factors and it is essential to verify the compliance with current urban planning regulations at the time of submission. Specific procedures exist to obtain retroactive approval (autorizzazione a posteriori), subject to strict legal conditions.

However, not every building violation is eligible for regularization. An unauthorized construction that contradicts fundamental planning laws cannot be cured and may result in a mandatory order to restore the property to their original layout.

A preliminary due diligence assessment determines whether regularization is achievable and outlines the expected costs and timelines.
