Building or renovating a villa in Mallorca is a project in which legal decisions made at the start determine both the cost and the final value of the property. Before works begin, the owner must know what the planning rules allow, which licence is required, how the contracts with the architect and the builder will allocate risk, and what protection exists if defects appear. Raso Investments advises private owners and investors on these questions, from the initial planning review to the handover of the finished works and any dispute that may follow.
Our role is legal, not technical. We work alongside the architect and other professionals chosen by the owner, making sure that the project is lawful and that the contracts protect the owner’s investment.
Planning rules when building or renovating a villa in Mallorca
The first question is always what can legally be done on the plot. This depends on the classification of the land, the applicable municipal plan, the rules adopted by the Consell de Mallorca for the island, and the regional planning legislation. On urban land, the plan sets parameters such as buildable area, height, setbacks and occupation. On rustic land, the possibilities are much more limited and are subject to specific regional and island rules.
The legal status of the existing building is equally important. A villa that includes works carried out without a licence may be classified as out of planning, which can restrict renovation to minor works and prevent extensions. This is why we recommend reviewing the licence history before buying a property to renovate. Our page on luxury villa due diligence explains that review.
Licences and authorisations
- Building licence. New buildings, extensions and major renovations require a municipal building licence based on a project drawn up by a qualified architect.
- Prior communication. Some minor works can be carried out after a prior communication to the town hall, but the scope of works covered is limited and must be checked case by case.
- Sectoral reports. Projects on rustic land, near the coast, in protected areas or affecting heritage may require additional reports or authorisations from other authorities.
- End of works and occupation. On completion, the architect issues the end-of-works certificate and the owner must obtain the documents required to occupy and use the building, including the certificate of habitability in the Balearic Islands.
Contracts with the architect and the builder
Many disputes in construction arise from contracts that are incomplete or that simply accept the builder’s standard terms. We draft or review the contracts with the following points in mind:
- A clear description of the works by reference to the project, the specifications and the quality of materials.
- The price, whether fixed or by measurement, and the treatment of changes and additional works.
- A timetable with milestones and, where agreed, penalties for delay.
- Payments linked to certified progress, with retentions as a guarantee until the defects period expires.
- Insurance, health and safety obligations, and responsibility for subcontractors.
- The procedure for handover, the list of snagging items and the start of warranty periods.
Warranties and liability for defects
The Spanish Building Act establishes liability periods for those involved in construction: one year for finishing defects, three years for defects affecting habitability and ten years for structural defects, counted from the handover of the works. Builders, architects, technical architects and developers may be liable according to their role. In residential construction, ten-year insurance covering structural damage is generally required, with limited exceptions, for example in some cases where an individual builds a single home for their own use. If the property is later sold within the ten-year period, the absence of that insurance can become an obstacle.
If problems arise during or after the works, see our page on property disputes in Mallorca, and our general page on procedural law and arbitration.
Common risks and mistakes
- Starting works under a prior communication when the works actually require a full licence.
- Extending or adding a pool on rustic land without confirming that it is permitted.
- Paying large advances not linked to certified progress.
- Accepting handover without documenting outstanding defects.
- Not obtaining the end-of-works documentation and the certificate of habitability, which affects supplies, letting and resale.
Tax aspects
Construction and renovation costs have tax consequences. Improvements properly documented with invoices can increase the acquisition value of the property for future capital gains purposes, while ordinary repairs cannot. The municipal tax on construction works is charged on the licence budget. The applicable VAT treatment depends on the type of works and the property. Each case is reviewed individually under the regulations in force. See our page on capital gains tax on property in Spain.
Where the works are financed by a loan, or carried out on a property owned through a company, the documentation of payments becomes even more important. We recommend that every payment to the builder or professionals is made by bank transfer against an invoice that identifies the works, and that the certificates issued by the architect are kept together with the licence and the end-of-works documents. This file supports any later warranty claim, the legalisation of the building in the Land Registry and the calculation of tax on a future sale.
Frequently asked questions
Can I add a swimming pool to my villa?
It depends on the land classification and the applicable rules. On some rustic land it may be possible with a licence; in other cases it may not be permitted.
Do I need a lawyer as well as an architect?
The architect designs and supervises the works. A lawyer reviews the planning position, drafts the contracts and protects you if things go wrong. The roles are complementary.
What if the builder abandons the works?
The contract should provide for termination, certification of the works carried out and the use of retentions. We assess the options and the claims available.
Can I renovate a villa I have just bought?
Yes, if the building’s legal status allows it and the necessary licence is obtained. Checking this before purchase avoids surprises.
