ITE and IEE building reports before buying a flat in Spain

Neutral editorial illustration of a building inspection; it does not depict a specific property or an actual ITE/IEE report.

Before buying a flat, it is useful to check not only its finishes but also the documents for the entire building. An ITE or IEE may contain information on condition, accessibility and energy efficiency, but its name, obligation, frequency and consequences depend on the autonomous community and municipality. The buyer needs an up-to-date document for the chosen building and evidence that its requirements have been fulfilled.

ITE and IEE are not universal quality certificates

Spanish rules are divided among national, autonomous-community and municipal levels. At national level, Article 29 of Royal Legislative Decree 7/2015 provides that the competent authority may require owners of collective residential buildings to certify their state of conservation, compliance with current universal-accessibility requirements and degree of energy efficiency. However, part of the former national provisions in that article was declared unconstitutional; the specific regime must be checked where the building is located.

Different territories use the names ITE, IEE and their own registers or forms. An age threshold and deadline from another city cannot be treated as applicable to the property. The first questions for the building manager and lawyer are: which document is required here, by which authority, as of what date and for which building?

What the document may show the buyer

The report helps establish which parts of the building were inspected, which deficiencies were recorded and which actions the authority required. An IEE may also address accessibility and energy performance. Yet a favourable result as of the inspection date does not guarantee that no hidden defects exist today. Leaks, works or a change in condition may have occurred between the report and the purchase.

Read more than the final classification. The date, building identification, signatory, inspected elements, findings, correction deadlines and annexes all matter. If the report refers to a separate project, completion certificate or municipal decision, request it. A manager’s statement that the building “passed the inspection” does not replace the complete set.

Minimum document request

• the current ITE/IEE, or written confirmation explaining why it is not required;
• evidence of filing or registration with the competent authority;
• the authority’s decision and result classification, where applicable;
• orders, deadlines and documents proving that findings were remedied;
• projects, permits and certificados final de obra for major works;
• community minutes, quotations, special assessments and payment status;
• later technical reports if the condition has changed.

Compare the report with the community minutes

Financial consequences may continue even when the inspection has formally ended. The community may have approved works to the façade, roof, lift or accessibility, allocated contributions and contracted a builder. Request minutes covering several years and the current budget. Establish separately which part of a special assessment has already been charged to the seller and which payments are expected after completion.

Do not infer too much from the absence of a line in the monthly community fee. Major works may be financed by separate contributions, a community loan or stages. The lawyer should check how the contract allocates expenses between the parties; the technical adviser should check whether the selected solution addresses the problem.

Check that the address and building scope match

A complex may include several blocks, a garage, commercial premises and common areas. Make sure the document covers the block and elements relevant to the flat. A matching development name is not enough. Compare the address, cadastral references or another identifier with the authority’s records.

If the flat is above a garage, below the roof or next to an expansion joint, the building’s overall classification does not remove the need to inspect those areas. Ask the engineer to read the ITE/IEE before the visit so that the listed locations and the result of repairs can be checked.

The report and current condition should corroborate each other

During the viewing, note recent localised painting, cracks, a damp smell, the condition of balconies, corrosion, drainage and accessibility of common routes. These observations are not a diagnosis. Give photographs and notes to the professional who will compare them with the report. An additional inspection may be necessary if the document is old or works remain incomplete.

The buyer should not interpret technical terminology as a promise of safety. A visual inspection, for example, has limitations; inaccessible areas and concealed structures may not be assessed. Look for the section describing methodological limitations.

Accessibility: inspect the entire route

A reference to accessibility in an IEE does not mean that the route from the street to the flat suits a particular person. Inspect gradients, thresholds, doors, the lift, turning spaces and the route to the garage. Permitted exceptions and reasonable adjustments may exist, but a specialist must determine their application under the current rules and to the building concerned.

If works are planned, establish whether the community has approved them, whether permits have been obtained and who pays. Do not rely on an advertising promise that a lift is “coming soon” without documents and a realistic timetable.

Energy efficiency in the IEE and CEE

Do not confuse an IEE with the energy performance certificate for the particular flat. Royal Decree 390/2021 regulates energy performance certification. Ask for the CEE and label relating to the property being purchased and verify registration. Building energy-performance information is useful, but actual bills depend on occupancy patterns and equipment.

If the document is missing or overdue

Do not automatically conclude that the sale is impossible, and do not accept an assurance that the document is “not needed by anyone”. Ask the lawyer to establish the obligation for the autonomous community, municipality, building type and age, and the consequences of its absence. The issue may involve an order, penalty, works and future expenditure.

Before paying a deposit, define in the contract which documents the seller must provide and what happens if the review produces a material result. Do not leave the phrase “everything is fine with the ITE” without a list of annexes and a date.

Building comparison sheet

1. Which ITE/IEE regime applies and when was it checked?
2. What was inspected and which areas were excluded?
3. Which findings were made and have they been closed with documents?
4. Which works have been approved or are under discussion?
5. How are the works financed and is there any debt?
6. Does the current condition match the report?
7. Is an additional engineer’s inspection needed?

Compare buildings using the same questions, not merely the word favorable. A good review result is a clear set of documents, completed actions and a budget that accounts for them. This material was checked on 25 October 2026; regional and municipal rules must be confirmed separately as of the transaction date.
