Something breaks in the flat. You call the landlord, he calls it normal wear and tear, you are not so sure, and nobody wants to be the one paying for the plumber. In Spain the answer is not a matter of goodwill or who shouts loudest — it is written into the law, and knowing the rule saves you both money and a lot of arguing. Here is how it actually works, from a dripping tap to a dead boiler.
Spanish rental law — the LAU, Ley de Arrendamientos Urbanos — draws one line and holds it. The landlord has to keep the property fit to live in. The tenant handles the small stuff that wears out from ordinary use. Article 21 puts it plainly: the owner pays for the repairs needed to preserve the home, and cannot pass that cost on through the rent, unless the damage is the tenant's fault. Ordinary wear and tear, the day-to-day knocks of living somewhere, is on you. It sounds neat until you try to work out which side a broken shower pump falls on.
There is no official price list, which is exactly why arguments start. The rough test courts and agencies use is whether the fix is about keeping the home habitable (landlord) or replacing something cheap that simply wore out (tenant). A washer that needs changing, a worn ring on a tap, a few lightbulbs, a drain you clogged — small, and yours. A boiler that dies, a leak from the ceiling, damp climbing a wall, the hot water cutting in and out, a fault in the wiring — that is the building and its installations, and it is the landlord's problem. When a repair is genuinely borderline, the paperwork you signed matters as much as the general rule.
The law has an escape hatch for this, and it is worth knowing. If a repair cannot wait and the delay would cause serious damage or leave you without something essential — no water, no heating in January, a leak flooding the flat — you can arrange the fix yourself and claim the cost back, as long as you tell the landlord first where that is possible and the problem is not your fault. Tell him, keep the message, keep the invoice. It is a safety valve for real emergencies, not a licence to call your own handyman for routine jobs and send the bill.
These are the cases that come up most in Spanish rentals. None of them is absolute — a lease clause can shift some of them, so read before you sign.
The single habit that prevents most disputes: report the fault in writing and do it quickly. A WhatsApp message with a photo and a date is enough to prove you did your part. If you sit on a leak for two months and it takes out the parquet, the landlord will argue you made it worse, and he may be right — under the LAU you are expected to tell him as soon as you know. Once you have reported it, the ball is in his court; if he ignores a serious problem, that is a breach on his side and can even affect the contract.
Before signing, ask what is included and who covers what. Some landlords write in a clause shifting appliance repairs onto the tenant, or the other way round. Under the LAU a blanket clause that pushes genuine habitability repairs onto the tenant can be challenged, but a clear and specific clause about a specific item usually holds. Meet the landlord or the agency halfway: agree in the contract who fixes the boiler, who pays for the annual air-conditioning service, and what counts as a small repair. Two sentences here save a winter of cold showers and arguments.
