Shared building ownership law: works, debts and communities

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

Ley 49/1960, sobre propiedad horizontal (LPH, Spanish shared building ownership law) governs relations between owners of properties subject to propiedad horizontal. It affects homes, commercial premises and common elements, as well as those representing the comunidad de propietarios (owners’ community). It provides a framework for maintenance, works and expenditure obligations. For a specific issue, check the título constitutivo (document establishing the ownership regime), statutes and resolutions, together with the component where the damage originates.

What you need to know

• The community must carry out certain necessary maintenance, safety and habitability works under article 10. A meeting having not yet approved a quotation does not make an established risk an exclusively individual problem.

• Article 9 establishes owners’ obligations, including contributions to common expenses. On purchase, the property is liable for amounts that have fallen due in the current year and the three preceding calendar years on the terms laid down by law.

• Review the community debt certificate with its date and scope. Distinguish outstanding balances, approved derramas (special contributions) and works still being considered. A certificate does not predict every expense that may subsequently be approved.

• Article 7 restricts alterations affecting safety, structure or external configuration and requires notification of internal works on its specified terms. Owning the space is not enough before removing a wall or enclosing a terrace.

• The voting majorities and requirements for resolutions depend on the subject. No single voting rule is valid for all works. Keep the meeting notice and minutes, and consult the applicable resolution before treating a conversation between neighbours as effective.

• An element for exclusive private use can remain common by its nature or ownership title. For terraces and roofs, distinguish use, maintenance, damage and responsibility; water entering your living room does not automatically determine who must pay.

Application to a home

Imagine a terrace used by just one home and damp appearing in the flat below. The starting point is not to split the bill by intuition. Gather the ownership title, waterproofing history and communications; identify whether a common layer, drain or private installation has failed. Maintenance and responsibility can then be established. Where there are several causes, a partial solution may remove the stain temporarily without repairing the source, so checking the proposed works also matters.

The duty to maintain an element and liability for causing damage do not always coincide. An owner may have altered a common arrangement, while a community may maintain an installation whose defect affects only one home. Separate those questions. When negotiating a repair, make clear what will be repaired, who commissions it and how the result will be checked, without turning access for repairs into a general waiver.

Documents to cross-check

Gather the document establishing the ownership regime and statutes, minutes relating to the works, debt certificate, quotations and invoices for previous interventions. Add photographs of both sides of the damage where possible and mark its location on a plan. If a pipe runs through several flats, request available information about its route; do not attribute ownership simply because you can see it inside your home.

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 the source of damp, the condition of a common element or the scope of a repair. 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.
