Purchasing an off-plan property in Spain remains one of the most common ways to access high-quality new-build homes on the Costa Blanca and other coastal regions. For many international buyers, the process is unfamiliar: staged payments, construction timelines, legal guarantees and developer obligations differ from those in the UK, Northern Europe or the US.
This guide sets out the essentials: what “off-plan” actually means, how payments are protected, what the law requires from developers, and the points every buyer should verify before signing.
What Off-Plan Means in Spain
An off-plan property is a home purchased before construction is completed often before building has started. Instead of buying a finished unit, you buy a legally approved project backed by:
- a building licence (licencia de obra),
- technical documentation defining the development, and
- a guaranteed payment structure regulated under Spanish law.
Off-plan does not mean paying the full price upfront. It also does not mean handing money directly to the developer without safeguards. Spanish regulations are strict, and payments must be protected.
Escrow and How Buyer Funds Are Protected
All payments made before completion must be deposited into a special escrow or blocked account used solely for construction costs of the project. Developers cannot use these funds for other activities or other developments.
Your lawyer should confirm:
- the details of the escrow account,
- the bank or insurance provider guaranteeing the deposits, and
- that each staged payment is covered by a bank guarantee or surety insurance.
Under Spanish law, if the developer fails to complete the property or deliver the home by the agreed date, buyers have the right to reclaim all protected funds plus interest.
The Legal Framework: LOE 38/1999
The regulation of new-build and off-plan homes falls under the Ley de Ordenación de la Edificación (LOE 38/1999).
This law establishes:
- the obligations of developers, architects and contractors,
- the requirement to protect buyers’ deposits, and
- the liability periods for construction defects.
The LOE is the backbone of consumer protection in Spain’s new-build sector and is one of the reasons off-plan purchases are widely considered safe — provided due diligence is carried out.
The 10-Year Guarantee (Decennial Structural Insurance)
Every new-build property in Spain includes a set of compulsory guarantees:
The 10-year insurance (seguro decenal) is especially important. Without it, the developer cannot obtain the final habitation certificate (licencia de primera ocupación), meaning the property cannot be legally delivered to buyers.
Typical Off-Plan Payment Schedule
While individual developments vary, most off-plan purchases in Spain follow a similar structure:
1. Reservation
A small reservation fee (€3,000–€10,000) removes the unit from the market for a defined period while contracts are prepared.
2. Private Purchase Contract (PPC / Contrato de Arras)
Usually signed within 2–4 weeks.
At this stage, buyers typically pay 10% of the purchase price, minus the reservation fee already paid.
3. Construction Stage Payments
Staged payments: often 20–30% in total are made during construction.
Each payment must be:
- deposited in the project’s escrow account, and
- protected by an individual bank guarantee.
Developers usually tie instalments to construction milestones (e.g., completion of structure, façade, or installations).
4. Final Payment at Completion
The remaining 60–70% is paid at the notary upon delivery of:
- the finished property,
- the habitation certificate, and
- the final bank guarantee release.
This final payment is often financed through a Spanish mortgage, which is common for international buyers purchasing new-build property in Spain.
What Buyers Should Verify Before Signing
A well-structured off-plan purchase is transparent and predictable. Before paying any deposit, your lawyer should confirm:
Project Legality
- Building licence (licencia de obra mayor) granted and in force.
- Developer registered and fully authorised.
- Technical project approved by the local municipality.
Financial Guarantees
- Bank guarantee or insurance for each payment.
- Escrow account details.
- Delivery deadline and penalty clauses.
Documentation Provided
- Full building specifications and materials list (memoria de calidades).
- Floor plans, orientation, parking/storage allocation.
- Community facilities and future maintenance obligations.
Developer Track Record
- Previous completed developments.
- Financial stability.
- Timelines met in earlier projects.
Good developers on the Costa Blanca are used to working with international buyers and maintain high transparency. Still, independent verification is essential.
