Sardinia Property Due Diligence Guide for American Buyers
Sardinia carries the permit irregularity and cadastral mismatch risks common across southern Italy, plus two island-specific complications: the coastal Piano Paesaggistico Regionale (PPR) and maritime access rights. All seven checks must be completed by an independent Italian attorney before the compromesso is signed and the deposit is paid.
Why Sardinia Requires Specialist Due Diligence
Depopulation in the interior, informal postwar construction, and incomplete cadastral updates have left a material portion of the Sardinian property stock with some form of irregularity in its legal record, the same pattern found across Sicily and Calabria. Sardinia adds a further layer: an island-wide coastal landscape protection regime and archaeological heritage overlays tied to the nuraghe (Bronze Age stone structures) scattered across the territory. This is not a reason to avoid the market. It is a reason to engage an attorney who has handled these specific issues before.
The Seven-Step Due Diligence Checklist
1. PPR Zone Classification
Determine whether the property falls within the coastal 300-meter PPR buffer and what specific renovation restrictions apply. This is the first check for any coastal or near-coastal property, and it should be run before you spend further time or money evaluating the property.
2. Title Search
Your attorney searches the Conservatoria dei Registri Immobiliari (Land Registry) to confirm the seller holds clear, unencumbered title. In Sardinia, inherited properties frequently involve multi-heir estates with unresolved succession, particularly in the interior villages. Confirm that the succession (successione ereditaria) is complete and properly registered.
3. Building Permit Conformity
Your attorney requests the building permit history (concessioni edilizie) from the municipality and compares the permitted structure to the actual building. Informal additions, enclosed terraces, and unauthorised floors are common across both the inland villages and older coastal construction.
4. Cadastral Conformity
The Catasto holds the registered floor plan (planimetria catastale) of the property. Your attorney compares this plan to the physical building and to the building permits. Unresolved cadastral discrepancies block a valid deed of sale.
5. Waterfront and Maritime Access Rights
For any property with direct sea access, a private path to the shore, or mooring rights, confirm the demanio marittimo (maritime public domain) access classification. These rights are separate from property ownership and are frequently misunderstood by buyers relying only on the listing description.
6. Heritage Designation (Vincolo)
Sardinia has significant archaeological and landscape heritage overlays, including proximity restrictions tied to nuraghe sites. A vincolo restricts renovation: exterior changes, structural modifications, and additions require Soprintendenza approval that may not be granted. Confirm whether the property or its land carries any vincolo before an offer is made.
7. Urban Planning Violations
Your attorney checks the municipal planning records for outstanding violations (abusi edilizi) registered against the property. Violations regularised through a condono (building amnesty) are generally acceptable if the process is complete and documented. Active unresolved violations represent a material legal risk.
Engaging the Right Attorney
Your Italian attorney for a Sardinian purchase should have specific island transaction experience, ideally with both interior village purchases and coastal PPR reviews, since the two present genuinely different risk profiles. Attorney fees for a standard interior residential transaction run 2,000 to 5,000 EUR. For coastal luxury purchases, budget 5,000 to 10,000 EUR given the added PPR and maritime access complexity. This is not where to economise.
Frequently Asked Questions
What is the PPR and why does it matter for Sardinian due diligence?
The Piano Paesaggistico Regionale restricts construction and significant renovation within 300 meters of Sardinia's coastline. It affects renovation scope, new construction, and exterior modifications. It must be checked before any coastal property offer, since it can block work regardless of what the current structure appears to allow.
Is the notaio responsible for buyer due diligence in Sardinia?
No. The notaio is a neutral public officer who executes the deed and collects transfer taxes. Your independent attorney performs buyer-side due diligence, including the PPR and maritime access checks specific to Sardinia.
How long does due diligence take in Sardinia?
Allow two to four weeks for interior properties and up to six weeks for coastal properties requiring a full PPR review. Municipal offices, particularly in smaller interior comuni, have variable response speeds.
