The snagging list for a new apartment may contain a scratched frame, a shower that leaks and a crack above a doorway. Putting them in one email is sensible administration. Treating them as one legal problem is less helpful. In Spain, the nature of the damage, the building's acceptance date and the time for bringing a claim can all matter. Start by creating an evidence file that someone else can understand without having visited your home.
Know which handover date you are looking at
A buyer normally remembers completion day: the deed was signed, the balance paid and the keys collected. Spanish construction law also uses a different event, recepción de la obra, when the contractor's completed work is accepted by the developer. That event may precede your purchase.
The Building Act, or LOE, links its material-damage periods to acceptance without reservations or the correction of those reservations, as applicable. Obtain the acceptance record and any document recording remedial completion. Do not substitute the date on your flight booking, first occupancy or purchase deed. The statutory framework is in LOE articles 6 and 17.
Keep three timelines: construction acceptance, your purchase and possession, and the emergence of each defect. This small distinction makes later conversations much more precise. If you have yet to buy, include these documents in your new-build purchase checks, alongside the sales specification and approved changes.
Understand the one-, three- and ten-year categories
Under LOE article 17, the contractor has a one-year responsibility period for material damage arising from execution defects affecting finishes or completion. Three years concerns construction or installation defects causing a failure of habitability requirements. Ten years applies to specified structural defects directly compromising mechanical resistance and stability. These categories concern qualifying damage; they do not make every problem in a ten-year-old home a structural claim. Read the statutory categories in the BOE.
A separate rule governs actions for that material damage: article 18 provides a two-year limitation period from when the damage occurs, without prejudice to contractual actions. Identifying the relevant event and the effect of communications or other legal steps requires case-specific advice. It is unsafe to read “ten years” as permission to wait ten years after noticing a problem. LOE article 18 sets out the action period.
A hairline crack does not classify itself. Its position, movement, underlying cause and consequences may matter more than its appearance in a photograph. Similarly, a damp patch may involve a window detail, pipework or a common roof. Record the symptom first; let investigation establish the cause.
Build a defect file that survives a change of contact
After-sales staff can change, subcontractors may visit separately and several owners may report similar problems. Give every issue a stable reference. Keep original photographs, then make annotated copies showing the location. A short video can explain intermittent behaviour better than several still images.
| Record | Useful detail | Avoid |
|---|---|---|
| Location | Apartment, room and exact component | “The wall” with no orientation |
| Observation | What happened, when and under which conditions | A guessed technical diagnosis |
| History | Previous reports, visits and attempted repairs | Deleting an issue after repainting |
| Outcome | Work completed and how the result was checked | Marking everything closed after a visit |
For example, a fictional buyer living abroad discovers water beneath a terrace door during a November stay. A neighbour remembers a similar event in September. Record each account separately, with its source and any dated images. Do not silently change the first recorded incident to November because that was your first personal visit.
Ask anyone attending to leave a written description of observations and work. Store invoices and receipts for necessary mitigation. Where urgent safety concerns arise, obtain prompt professional help; evidence gathering should not delay essential protective action.
Commission a technical report with a defined question
A useful instruction is more specific than “check the apartment”. Explain whether you need to establish likely cause, document the extent of damage, assess urgency or evaluate a proposed repair. Ask what the inspection can establish without opening concealed parts and what further tests would require permission.
The guide to property inspections in Spain explains how to compare scope and limitations. A mortgage valuation or a developer's internal job sheet serves a different purpose from a report investigating a recurring defect.
Provide the sales specification, drawings available to you, building documentation, maintenance records and previous repair notes. The Spanish Building Code includes requirements concerning use and maintenance documentation. Those records help the professional distinguish construction performance from later alterations or maintenance issues.
If the suspected source is a shared roof or façade, involve the community's representative. Your apartment's damage and the communal cause may need coordinated access and investigation. Keep your own evidence even where a collective discussion is already underway.
Separate the developer, contractor and insurer
Your sales contact may be an effective starting point, but retain the legal names and addresses of the developer, contractor and relevant professionals. The LOE contains rules allocating responsibility between participants. A practical repair conversation and a legally effective claim are connected tasks, not necessarily the same document.
Send a clear, traceable description identifying the property, issues, evidence and response requested. For significant damage, disagreement or approaching deadlines, obtain advice on recipients and delivery method. Do not assume a casual message to a salesperson deals with every limitation issue.
Insurance needs its own check. Obtain the actual policy details and claims procedure. Our self-builder's guide to ten-year structural insurance explains why this cover should not be confused with a promise that all snagging, appliances or cosmetic repairs are insured. The policy and the statutory responsibility framework require separate reading.
Accept a repair only after defining a sensible check
Ask what will be repaired, when access is needed, which finishes will be reinstated and what evidence will show the underlying problem has been addressed. A newly painted ceiling may look reassuring while telling you little about the roof above it. Record a repair as completed before recording the defect as resolved.
Add the final reports to your Spanish home purchase file. Buyers planning their own build can use the same document discipline when comparing construction quotes and choosing a builder.
For your next step, collect the acceptance record, purchase specification and a dated incident list. If you are planning a purchase or construction project, tell us the location, stage and issue you want to clarify, so your enquiry starts with the details that matter.
