Libro del Edificio in Mallorca: The Maintenance Manual for New-Build Properties

Responsible for this content: Frank Menze

When you take over a newly built property in Mallorca, you normally get more than just the keys: the developer owes you the Libro del Edificio – the complete technical and administrative documentation of what was actually built. Many buyers have never heard of it, and confuse it with the energy certificate or with the entirely different Informe de Evaluación de Edificios (IEE), which concerns older existing buildings. This guide clearly separates the two documents, explains what you should insist on at handover, why a missing Libro del Edificio can even make registering your property in the land registry more difficult – and from what point the ten-year IEE obligation applies to you as the owner of an older building.

Libro del Edificio Mallorca: Rights and Obligations

Is the Libro del Edificio missing for your new build, or are you unsure whether your existing house already needs an IEE?

Libro del Edificio vs. IEE: the difference at a glance

Both terms are often used loosely in everyday language as "the papers for the house" – yet they cover two completely different situations. One you receive when building, the other you owe as the owner of an old building.

Feature Libro del Edificio Informe de Evaluación de Edificios (IEE)
Legal basis Art. 7 LOE (Ley 38/1999) Ley 12/2017 (LUIB), Balearic Islands
Created during construction, prepared by the developer recurring, commissioned by the owner
Who receives it end user / buyer submitted to the municipality
Applies to new builds and major renovations buildings 50 years or older
Frequency one-off, accompanies the building permanently renewed every 10 years
Purpose Documentation of the work carried out, maintenance Condition assessment of existing buildings

Note: If you're buying a resale property, both can theoretically be relevant – the original Libro del Edificio from the time of construction and, if the building is old enough, a due IEE. During the property inspection, check both separately.

What exactly is the Libro del Edificio?

The legal basis is provided by Article 7 of the Ley 38/1999, de Ordenación de la Edificación (LOE). It states, in essence, that all documentation relating to the work carried out forms the Libro del Edificio and must be handed over to the end users of the building. That's the crucial sentence: the Libro doesn't belong to the developer, the architect, or the building management – it belongs to you as the buyer, or to the community of owners.

Two consequences follow from this for everyday life in Mallorca:

  1. It is not a single form, but a collection of documents relating to the building as actually constructed – not what was originally planned, but what was ultimately built in the end.
  2. The developer is obliged to hand it over to you at completion. If you don't actively request it, experience shows it often ends up, in practice, in a drawer at the site management office rather than with you.

Attention: A missing Libro del Edificio isn't just an inconvenience. It can prove decisive later on if you need to prove a construction defect or make a warranty claim – more on this in the guide to construction defects and liability in Mallorca.

What is usually included in the Libro del Edificio

The exact required content is governed by the preceding paragraphs of Art. 7 LOE and is compiled differently in practice by architecture firms and developers. Without prescribing a definitive legal list, the following are typically included in practice:

Typical component Benefit for you as the owner
Project documentation of the work carried out Proof of what was actually built
Acceptance and completion certificates Basis for later defect claims
Maintenance instructions for installations Basis for maintenance planning
Registration records for technical installations Necessary for maintenance contracts and inspections
Warranty documents from the contracting companies Important in the event of complaints

Note: This list is a practice-based guide, not an exhaustive legal catalogue. If in doubt, request written confirmation at handover of exactly which documents are included.

When do you receive the Libro del Edificio – and what if it's missing?

When buying a new-build property, handover of the Libro del Edificio is part of the key handover. If it is missing, you should demand it in writing from the developer before paying the final instalment or signing off on acceptance. If you are buying an off-plan property, handover of the Libro del Edificio should be included in the handover clause of the purchase contract.

The document also becomes practically relevant at the Land Registry: for the registration of a completed new-build declaration (obra nueva terminada), the Land Registry checks compliance with the building-law requirements for handover to users – and this includes the Libro del Edificio. If it is completely missing, this can make registration of the property more difficult or delay it. If in doubt, have this confirmed in advance by your lawyer for the property purchase and check the land registry entry.

Note: Whether a missing Libro del Edificio will cause your specific purchase contract or your financing to fail depends on the individual case and the notary or Land Registry involved. A blanket statement on this cannot be made responsibly – clarify this individually before notarisation.

The Informe de Evaluación de Edificios (IEE) in the Balearics

The IEE works quite differently. It does not concern the construction of a new building, but the recurring condition assessment of existing buildings. It is based on the Ley 12/2017, de urbanismo de las Illes Balears (LUIB). Under this law, owners – natural or legal persons as well as owners' associations – of buildings that have reached an age of 50 years must submit an IEE every 10 years.

Exempt from this obligation are structures of minor architectural significance and simple technical execution, as defined in national legislation.

Criterion Regulation under LUIB
Buildings affected Buildings 50 years or older, excluding structures of minor architectural significance and simple technique
Inspection interval renewed every 10 years
Who submits it Owner or community of owners
Where it is submitted to the relevant municipality
Exception Buildings of minor significance as defined by the state

Please note: The specific deadline for the first IEE, the procedure and a possible municipal register are regulated by the municipalities in their own ordenanzas. A common municipal pattern sets a deadline of no more than five years for the first report, starting from when the building reaches 50 years of age or from completion of works that changed the architectural configuration – or the deadline expressly set by the town hall. However, this is a municipal regulatory level, not a Balearic-wide deadline. Check with your own municipality about the rules that apply there.

You can find out more about the procedure and the building assessment itself in the guide IEE/ITE Obligation Mallorca.

What applies if you own a flat in a community?

For owners of a flat, one rule is particularly convenient: if the IEE is drawn up on behalf of the community of owners for the whole building, this one report has effect for every individual flat and commercial unit in the building. As an individual owner, you therefore don't need to commission an additional report yourself if the community has already done so.

Conversely, this also means: if you own a flat in an older building, check whether the community of owners has organised the IEE within the deadline – as an individual owner you benefit from this, but you also have an interest in the community fulfilling its obligation.

Fuera de ordenación: limits on renovation works

For buildings classified as fuera de ordenación, an additional restriction applies: even if the IEE recommends or requires certain works, only the measures explicitly permitted by the relevant LUIB provision for such buildings may be carried out there. A positive or negative IEE finding does not lift this urban planning restriction. You can find details on this in the guide Fuera de Ordenación Mallorca.

Who is allowed to sign the IEE?

For the IEE, the following applies: it may be signed by anyone with the professional qualification under the LOE – that is, professionals who are permitted to draw up building projects or take on site management, as well as registered inspection bodies with suitably qualified staff. In practice, the Libro del Edificio is compiled by the architects involved in the construction and the site management; no comparable explicit statutory signing rule for this document has been established here. For practical help finding professionals near you, it's worth taking a look at the Construction & Renovation Directory.

Note: There is no official fee schedule for the cost of drawing up a Libro del Edificio or an IEE. In individual cases, get several quotes from qualified professionals rather than relying on a flat rate figure.

Most common mistakes when handling the Libro del Edificio

  • Not actively requesting it: Buyers rely on the developer to hand over the Libro of their own accord – in practice, it's often forgotten or only provided upon request.
  • Confusion with the energy certificate: The energy certificate is a separate document and does not replace the Libro del Edificio.
  • Confusion with the IEE: Anyone expecting an IEE for a 15-year-old new build is confusing the two systems – the 50-year threshold only applies to the IEE.
  • Missing handover clause in the purchase contract: Without an explicit contractual obligation to hand it over, its absence becomes harder to enforce later.
  • Ignoring the community's joint IEE obligation: Individual owners assume it "isn't their business," even though the community as a whole is responsible.

Checklist: Libro del Edificio when buying a new build

  1. Before signing the purchase contract: Agree on the handover of the Libro del Edificio as an explicit clause.
  2. At the key handover: Check the completeness of the documents together with a professional.
  3. Before the final payment: Obtain confirmation that the Libro matches the building as actually constructed.
  4. Before notarisation: Clarify with your lawyer whether all requirements for the land registry entry of the obra nueva terminada have been met.
  5. After moving in: Keep the Libro safe and stored permanently – it accompanies the building for decades.

What comes next?

Once the Libro del Edificio has been handed over, it's best to keep it permanently within reach – for example, together with the energy certificate and the documents relating to the building permit. It becomes relevant as soon as you later renovate, sell or assert warranty claims. Once your building reaches the 50-year mark, the perspective shifts: the IEE then takes over the role of ongoing condition documentation, and you should find out in good time from your municipality about the applicable deadlines and procedures.

Conclusion

The Libro del Edificio is not bureaucratic paperwork, but your technical file on the building – and legally speaking, your property once you become the end user of the property. Actively demand it when buying a new build, before you pay the final instalment. For older existing properties, the crucial question is different: has your building reached the 50-year threshold, and is there a valid IEE in place? Both documents relate to different phases of your property's life – confusing them risks evidentiary problems in the event of construction defects in one case, and an overlooked municipal obligation in the other.

Official sources

What is the difference between the Libro del Edificio and the Escritura?
The Escritura is the notarial purchase contract for the property, while the Libro del Edificio is the technical documentation of the completed construction work. Both documents are independent of one another and do not replace each other.
Does the developer have to hand over the Libro del Edificio automatically?
Under Art. 7 LOE, handover to the end users is provided for, but in practice you should actively request it and set it out as a clause in the purchase contract.
Does the IEE also apply to single-family homes?
Yes, the obligation under the LUIB applies to buildings aged 50 years or more regardless of whether it is a leasehold flat or a single-family home, with the exception of structures of minor architectural significance.
Who has to commission the IEE for a leasehold flat?
As a rule, the owners' association commissions the IEE for the entire building. Such a communal report automatically applies to every individual flat within it.
What happens if the Libro del Edificio is missing when registering the property in the Land Registry?
Missing documentation relating to the handover to the users can make it more difficult to register the completed new-build declaration. Clarify this in advance with your lawyer or notary on a case-by-case basis.
Are there fixed fees for preparing a Libro del Edificio or an IEE?
No, there is no official fee schedule for this. Get several quotes from qualified professionals.
How often does the IEE need to be repeated?
Under the LUIB, every ten years once the building has reached the 50-year threshold.
Does the Libro del Edificio also apply to major renovations?
The LOE documentation requirement relates to completed construction work; for major renovations, it is worth clarifying with the responsible architect exactly which documents need to be produced.
