When the new build is late: your rights when delivery is delayed

You had circled the day on the calendar. June, September, the following March: the date you were going to drop your suitcase in the hallway of your new-build flat on the Costa Blanca. And then the crane is still there, the developer's email arrives with the word "unforeseen" in it and the date moves a quarter, sometimes two.

A delay on a new build is not an abstract drama. The Alicante province alone has more than a hundred developments with completion dates announced for 2025 and 2026 according to the main sector portals. Each time one slips, families renew rental contracts, couples postpone moves and overseas buyers reshuffle flights. The sensible question is not whether developers are allowed to be late. It is what happens when they are.

Why a development runs late in 2026

Before reading clauses, understand the context. The Spanish construction sector has been repeating the same diagnosis for two years now: the lack of skilled labour is the main cause of delays according to 75 % of directors consulted by the construction lobby in the global survey published in October 2024. The average age of a Spanish builder rose from 37.3 in 2007 to 45.1 in 2022. There is no generational handover, and you can feel it in the speed at which a floor slab gets poured.

Add the rise in material costs (90 % of Spanish firms report increases, almost twenty points above the international average), the bottlenecks in electrical connections and the heavy municipal paperwork. The uncomfortable conclusion is that a three- or six-month delay does not always signal bad faith. Sometimes it is a snapshot of a stretched industry.

That does not free the developer from his obligations. It just helps you understand who you are negotiating with.

The date in the contract: the first document to read

When you signed the private purchase contract, the delivery date had to appear there "with full clarity". Spanish case law is strict about that wording. A formula like "foreseeably during the second semester" leaves the developer with room to slide the milestones without consequences. A formula like "before 30 September 2026" pins him down.

If your contract belongs to the second category and the date passes, you already have your first piece of documentary evidence. You do not need anything else to start the conversation.

The money you have already paid is guaranteed by law

The Law 38/1999 of Building Regulation, in its First Additional Provision, requires the developer to guarantee every amount he receives on account before delivery. That guarantee takes the form of a bank guarantee or a surety insurance policy, individualised for each buyer and deposited in a special account. It is not a favour. It is a legal duty.

If the works do not start or do not finish on time, the path is clear. You serve the developer a formal written demand (burofax with proof of receipt, almost always) for the return of the amounts paid, the taxes paid on top and statutory interest. He has thirty days to refund. If he does not, you go straight to the guarantor or insurer with the guarantee or the policy in hand, and they answer with their own balance sheet.

Keep proof of every transfer from day one. Without it, the guarantee becomes abstract.

When a delay lets you walk away from the contract

The Spanish Supreme Court has been clear: a delay in delivery is a breach by the seller, even when it is not particularly long. That gives you two paths once the date has passed.

The first is to demand performance. You ask for delivery and you claim the damages the delay caused you. You keep buying the home.

The second is to terminate the contract. You hand back the promise, recover the amounts paid with their interest and also claim damages. Here the Law 38/1999 guarantee does the heavy lifting.

The choice is not trivial. If the development is in an area where prices have risen between signature and today (Jávea, Moraira, the new outskirts of Dénia), holding on to the contract may be more profitable than getting your money back. If the area has cooled or your personal situation has changed, terminating sets you free.

The penalty clause and the limits on the judge

Many modern contracts include a penalty clause: a daily or monthly amount the developer pays you for each day of delay, up to a cap. The figure replaces any open argument about how much the delay actually cost you. You collect what was agreed.

Article 1154 of the Civil Code lets the judge moderate that figure if he considers it disproportionate. But the Supreme Court has clarified in recent years that this moderating power only applies when performance was partial. If what was agreed was exactly "so many euros per day of delay in delivery" and the developer is late by exactly that, the judge cannot trim the figure. It applies as written.

The "in re ipsa" damage: the ruling that changed the conversation

The Supreme Court ruling 623/2014, dated 18 November, sealed a right buyers had been claiming for years: the mere loss of the use of your home is already a compensable damage in itself. You do not have to prove you paid rent elsewhere or stayed in a hotel. It is enough to show that the home was not delivered on time.

The Supreme Court called it damage "in re ipsa", "in the thing itself". If you bought to live there and you could not, there is a harm that is presumed. Courts then calculate the use-value through objective criteria, typically the market rent of a comparable flat over the months of delay. It is a calculation, not a piece of paper.

The first occupancy licence in the Valencian Community

Another very local detail. In the Valencian Community the old habitability certificate was replaced in 2004 by the Responsible Declaration of First Occupancy, processed by the relevant town hall (Alicante, Elche, Dénia, Calp, wherever the home sits). Without that filing, the home cannot be occupied legally, the definitive utility supply is not switched on and the notary cannot sign the deed.

If the developer invites you to take delivery of a finished building but the first occupancy licence is not yet processed, that is not a complete delivery. And the days keep counting.

Force majeure and the bankruptcy of the builder

The developer has an escape route: force majeure. A pandemic, a natural disaster or an unforeseeable regulatory change can suspend the deadline. But the burden of proof is his, and the courts are demanding. A short transport strike, a rise in cement prices or the delay of one specific supplier do not usually qualify.

The developer also cannot hide behind the bankruptcy of the builder he hired. Spanish Supreme Court case law, repeated frequently in the last decade, has made clear that the developer answers to the buyer even when the builder enters insolvency proceedings. Choosing a solvent builder is the developer's risk, not yours.

The day the keys do arrive

Delays end, almost always. The crane comes down, the windows go in, the entrance hall lights up and one day you get the phone call you have been waiting for. By then you already know the stones in the path: walk through the home with care, check the first occupancy licence, sign the delivery minutes and keep everything in one folder.

And if the road had extra days in it, there are laws and rulings that give you tools to settle the accounts. You do not always have to reach a courtroom. Often it is enough to know the terrain for the conversation with the developer to change tone.
