Luxury villa due diligence in Mallorca requires more than a standard conveyancing check. High-value villas are often located on rustic land, have been extended over several decades and include pools, guest houses, garages and terraces whose legal status is not always what the sales particulars suggest. At Raso Investments we examine these points for the buyer before any binding commitment, so that the price reflects what can legally be owned, used, insured and later sold.
The aim is not to find reasons to abandon a transaction, but to identify risks early enough to negotiate, require corrective action from the seller, or adjust the price and contractual protections.
Why luxury villa due diligence in Mallorca is different
A large proportion of Mallorca’s detached villas stand on land classified as rustic (suelo rústico), where building is heavily restricted. Island and regional planning rules have changed many times, and buildings that were lawful when first constructed may have been extended later without a licence. Some works can no longer be subject to demolition because the period for the authorities to act has expired, but they may still be considered out of planning (fuera de ordenación), which limits future works. Other breaches, particularly on protected rustic land, may not be subject to any time limit at all.
Coastal properties raise additional questions under the Spanish Coastal Law, which regulates the public maritime-terrestrial domain and the protection zones next to it. Easements of access, transit and protection can restrict what may be built or used close to the shore.
What we review on a villa
- Land classification and plot. Urban or rustic classification, protection categories, minimum plot rules and any discrepancies between the Land Registry, the Cadastre and the physical boundaries.
- Building licences and final certificates. We compare the licences and end-of-works certificates with what is actually built, including the main house, annexes, guest accommodation and outbuildings.
- Swimming pools, terraces and annexes. Pools, porches, pool houses and garages are frequently added without authorisation. We check whether they are covered, whether they can be legalised and what that would involve.
- Unauthorised works and planning proceedings. We consult the municipality, and the Consell de Mallorca where relevant, about any open disciplinary or sanctioning proceedings and about the risk of future action.
- Coastal law constraints. For seafront properties, the position of the maritime-terrestrial boundary and the applicable easements.
- Charges and encumbrances. Mortgages, seizures, rights of way, water rights, shared access roads and agreements with neighbours.
- Utilities and services. Water supply, wells and their authorisation, septic systems, and electricity connection in rural locations.
- Tourist rental registration. Whether the villa holds a registration that can be maintained by a new owner. See our page on the holiday rental licence (ETV).
How we work
We begin with the documents available from the agent or the seller and with our own searches at the Land Registry and the Cadastre. Where planning questions arise, we review the municipal files and, when needed, work with an independent architect or surveyor instructed by the buyer to compare the documentation with what is on site. Our findings are delivered in a written report that distinguishes between risks that are acceptable, risks that should be addressed in the contract and risks that justify renegotiation or withdrawal.
When the review is complete, we translate the conclusions into contractual protections: conditions precedent, seller warranties, retentions from the price, specific obligations to regularise works before completion, or the right to recover the deposit. You can read about the wider purchase process on our page on buying property in Mallorca.
Common risks and mistakes
- Assuming that because a building appears in the Cadastre it has a valid licence. The Cadastre is a tax register and does not confirm planning legality.
- Paying for built area that is not registered or cannot be legalised.
- Planning major renovation works without first checking whether the existing building is out of planning, which may prevent anything beyond minor repairs.
- Ignoring the cost and time needed to legalise works, where legalisation is possible at all.
- Relying on verbal assurances that a tourist rental licence will be transferred.

Tax aspects
A luxury villa can have significant tax consequences beyond the transfer taxes paid on purchase. Ownership may give rise to obligations under wealth tax and the solidarity tax on large fortunes, and the choice between buying personally or through a company affects income, capital gains and inheritance taxation. The amounts and thresholds depend on each case and on the regulations in force, so we assess them individually. Our tax law team can review the structure before you sign.
The tax review should also anticipate the exit. Improvements and legalisation costs that are properly documented may later increase the acquisition value of the villa for capital gains purposes, while undocumented works cannot be taken into account. Where the seller is not resident in Spain, the buyer must also withhold part of the price for the Tax Agency, a point we coordinate with the notary at completion. Each case is reviewed individually under the regulations in force.
Frequently asked questions
Can unauthorised works be legalised?
Sometimes. It depends on the land classification, the type of works and the rules in force. In some cases legalisation is possible through a specific procedure; in others, particularly on protected rustic land, it may not be.
What happens if the pool has no licence?
The consequences vary. It may be legalisable, it may be beyond the period for enforcement, or it may expose the owner to sanctions. We assess each case before you commit.
Does the seller have to fix planning problems before the sale?
Not automatically. That is a matter for negotiation, which is why the findings must be available before signing the private contract.
How long does a villa due diligence take?
It depends on the complexity of the property and the responsiveness of public bodies. We indicate a realistic timetable once we have seen the documents.
