Land Law: maintenance duties and building assessment reports

Last reviewed: 10 October 2026. This summary is for information only and is not legal advice; the only legally valid text is the one published in the official gazette.

What it regulates and who it affects

The consolidated Ley de Suelo y Rehabilitación Urbana (Spanish Land and Urban Rehabilitation Law) establishes rights and duties relating to land and buildings. For owners, the maintenance duty and its relationship with rehabilitation works are particularly relevant. It must be coordinated with regional and municipal legislation. Its provisions on building assessment include annulled sections: the original wording cannot be used as a fully applicable national obligation.

What you need to know

• Article 15 includes maintenance duties and use compatible with planning rules. Ownership entails maintaining the required conditions, even without a municipal notice or a fault affecting every neighbour.

• Article 16 addresses the maintenance duty for buildings. The need for works must be analysed under its terms, scope and limits; it is not authorisation to renovate without the required administrative permissions.

• Article 29.1 provides for the competent authority to require evidence of maintenance condition, accessibility and energy efficiency in collective residential buildings. The specific obligation must be checked against the territorial rules.

• Paragraphs 2 to 6 of article 29 and article 30 were annulled by the Tribunal Constitucional (Spanish Constitutional Court). Do not cite their rules as applicable or infer professional authorisation or a universal frequency from them.

• An ITE (Inspección Técnica de Edificios, building inspection) or IEE (Informe de Evaluación del Edificio, building assessment report) is not an inspection of every finish in the flat you are buying. Request the report, outcome, outstanding actions and evidence of remedy, alongside checking the particular home’s condition.

• Article 28 governs documentation for declarations of new construction. A construction’s Land Registry entry and planning status must not be confused with certifying the physical quality of every component.

Application to a home

An owners’ community knows about falling façade material and receives rehabilitation quotations. Before choosing solely by price, identify protective measures, the cause and technical scope. The maintenance duty requires addressing the risk, while a claim against whoever caused it needs a different assessment. If buying in that building, checking only the debt certificate omits works that have not yet been approved and outstanding inspection documentation.

Maintenance, planning legality and civil liability are related but distinct matters. An orden de ejecución (administrative order requiring works) can require action without resolving who must ultimately bear damage costs between private parties. Nor does a favourable inspection guarantee the absence of concealed installation problems or new defects. Check the report’s date, examined parts and limitations to understand which conclusion it supports.

Documents to cross-check

Request building reports, notices, orders requiring works, minutes, quotations and documents showing remedy. Identify the address, cadastral reference and affected elements. For a purchase, gather the Land Registry description and documents for later interventions. Distinguish the repair design, execution and completion certificate: do not assume an obligation is completed because a quotation has been approved or an invoice issued.

Key deadlines and figures

Do not confuse the moment an issue appears with the deadline for bringing a legal action. Keep the documents establishing each milestone and use the table only for the situation it describes. Where a row refers to a contract or decision, consult that document: there is no universal figure that can replace it.

What to do if it affects you

1. Identify the transaction and applicable law. Record the municipality, contract date, handover date and the parties’ status. Distinguish a purchase, a letting, maintenance work and a damages claim. This classification avoids applying a time limit from a different situation and allows you to seek legal advice with specific facts.
2. Build a verifiable case file. Keep the original documents and make working copies. Organise photographs by date and room, retain complete messages and connect every payment to its purpose. If a document is missing, record your request for it; missing information must not be filled with assumptions about what happened.
3. Describe the problem and its extent. Explain what you observed, where and since when, separately from what you believe caused it. Record any parts that could not be inspected and whether people or property are affected. Where there is a risk, prioritise protection and document the necessary measures before continuing the financial dispute.
4. Communicate with a traceable record. Address your letter to the relevant person or organisation and retain evidence of its content, dispatch and receipt or attempted delivery. Identify the home, issue and attached documents. Request a specific response and distinguish asking for information, claiming damages and proposing negotiation: they may have different effects.
5. Check the time limits with advice. Maintain a chronology of communications and actions, without assuming that a call, visit or promise to repair something extends the deadline. If court proceedings are being considered, seek advice on the prior negotiation requirement, its exceptions and effects on prescripción (limitation) or caducidad (expiry of an action). An administrative procedure does not automatically replace that step.
6. Define a solution that can be checked. If repairs or a settlement are offered, specify the work, access, documents, acceptance and subsequent verification. Keep evidence of the previous condition and records of any intervention. Before signing a waiver, final settlement or acceptance without reservations, review its scope so you do not close issues that remain unresolved.

How an expert can help

An expert can provide a technical basis where the problem requires checking maintenance condition, observable damage and repair priorities without replacing the building’s regulated documents. The report must identify what was inspected, which documents were used and any limitations. Its conclusions must distinguish observations, sufficiently established causes and unresolved questions. A legal disagreement cannot be resolved simply by adding photographs, and an expert opinion does not replace the authorisation required for regulated certificates or designs.

Verify Home Inspector can consider an inspection or expert assessment within its specialism and the agreed scope. To discuss availability and work, you can request a quote. Before commissioning, clarify whether you need measurements, a financial assessment, a further visit or preparation for confirming the report in court, as these are different tasks and must not be assumed to be automatically included.
