Signing Off on Your New Build in Spain

A thorough final inspection can save months of post-handover problems.

Reaching the final stages of a construction project is an exciting milestone. Whether you are building a bespoke luxury villa in Marbella or developing a multi-unit resort on the Costa del Sol, the finish line is finally in sight. However, before you accept the keys and sign off on a new build, there is a critical phase that dictates the long-term success of your investment: the final handover and “snagging” process.

At MDCI, we have over 30 years of experience managing luxury developments and protecting our clients’ interests through professional Project Management in Spain. We know that modern construction is complex, and the final 5% of a project often requires the most rigorous attention to detail. Accepting a building prematurely can lead to unforeseen costs, delays, and endless stress.

To help you navigate this final hurdle and avoid the pitfalls of modern construction, our project management experts have compiled a comprehensive checklist of what you must verify before final sign-off on your new build. We hope it will help you to avoid common problems people face when they move in.

1. Legalities, Licenses, and Paperwork Required Before Sign-Off

In Spain, a physical completion is not the end of the story, sign-off from the authorities and the receipt of the correct paperwork is just as vital – and an important part of the process. Never sign off without verifying the following Spanish Construction Licenses:

• Certificado Final de Obra (CFO): The architect and technical architect (Aparejador) must sign this document certifying the works have been completed according to the licensed project. This allows for the liquidation of the work, the guarantee process to commence and the LPO application to begin.
• Boletines (Installation Certificates): Check that you have the official stamped certificates for electrical, water, gas, and telecommunications installations.
• Warranties and Manuals: Collect all manufacturer guarantees for appliances, HVAC systems, pool machinery, and the Libro del Edificio (The Building Book), which outlines ongoing maintenance requirements.
• Licencia de Primera Ocupación (LPO): Ensure the First Occupation License has been granted by the local Town Hall (Ayuntamiento). Without this, you cannot legally live in the property or connect utility meters in your name.

2. Exterior, Shell, and Landscaping Checks

For luxury villas and resorts, the exterior presentation and structural integrity are paramount.

• Façade and Roof: Inspect for any cracks, uneven rendering, or missing roof tiles. Ensure gutters and downpipes are correctly installed and clear of construction debris.
• Waterproofing and Drainage: Check terraces, roofs, and basements. Southern Spain experiences heavy seasonal rains, yet flat roofs are common, so proper drainage and damp-proofing are absolutely essential to prevent leaks.
• Pool and Gardens: Verify the pool machinery is fully operational, pool tiles are intact, and the automatic irrigation system for the landscaping is functioning properly.
• Boundary Walls and Gates: Test all automated entry gates, intercoms, and ensure boundary walls meet the specified heights and architectural finishes.

3. Interior Snagging Checklist

This is where microscopic attention to detail saves you from future headaches. Look out for problems in the following areas:

• Flooring and Tiling: Tap tiles lightly to check for hollow spots which indicate poor adhesion. Ensure grout lines are clean and consistent, and that there are no scratched or chipped tiles.
• Walls and Ceilings: Look closely at the plastering and paintwork under both natural and artificial light to spot uneven surfaces, drips, or hairline cracks.
• Doors and Windows: Open and close every door and window. Check that locks work smoothly, weather seals are intact, and there are no scratches on the glazing or aluminium frames.
• Joinery and Cabinetry: Inspect built-in wardrobes, kitchen cabinets, and luxury fittings. Check alignments, test soft-close hinges, and review the surface finishes for damage.

4. Testing Utilities, Climate Control, and Smart Home Systems

Luxury properties in Spain rely heavily on sophisticated Mechanical & Electrical (M&E) systems and these all need to be checked to ensure they are working correctly.

• HVAC (Heating, Ventilation, and Air Conditioning): Test the air conditioning on both hot and cold settings. If aerothermal underfloor heating is installed, verify that the manifold is properly labelled and the system reaches the desired temperature in each zone.
• Plumbing: Turn on all taps and showers, and flush all toilets. Check water pressure and look for any immediate signs of leaks under sinks. Ensure hot water arrives promptly to the furthest bathrooms.
• Electrics and Domotics: Test all sockets and light switches. In high-end builds, ensure the Smart Home (domotics) system is fully integrated, programmed correctly, and that you have been trained on how to use it.

5. Understanding Financial Retentions in Spain

It’s a legal requirement in Spain that a 5% quality retention is made from all of the monthly payments to the main contractor. These retained funds are to cater for “hidden construction defects” within the 12-month guarantee period. This protects owners from quality issues, electrical faults or water damage which often don’t become apparent for a significant period of time and ensures there’s money put aside to fix these issues. However, this is not designed to cover minor snagging items which are easy to see at the completion of the project. These should be identified and resolved before handover and before the final payment is made.

Conducting a thorough final inspection requires technical knowledge, a trained eye, and a deep understanding of Spanish construction standards. Without the right experience or the time to keep things on track, it is easy to overlook defects that could turn into costly liabilities. There are specialist snagging companies who can come in at the end of the project and produce a report to be given to your constructor if you don’t have a project manager.

Should I Hire a Project Manager for a New Build in Spain?

A professional project manager can oversee snagging, contractor coordination, legal compliance, and quality control throughout the build process.

One of the roles of our dedicated, multi-lingual Project Management team is to manage the final handover, including snagging, reporting and working with the construction team to put right any defects.  This is just one part of our role and how we protect your interests every step of the way through your project.

For clients who do not require full project management services, we offer independent construction project monitoring with comprehensive monthly reporting to keep you fully informed at every stage of the build.
