Avoid Costly Mistakes: The Importance of Local Knowledge in Spanish Construction
There’s a common misconception when international individuals or investors build in Spain, that it’s better to use builders from outside of Spain. However, in our 27 years of project managing construction projects in Spain, we can tell you that nine times out of ten this is not correct. That’s because, local knowledge and oversight is crucial to successfully complete a project on time, on budget and in line with local regulations.
When international teams come over here, they bring their own working practices, materials and approach, which is highly successful in their home country, but may not be suitable, or even allowed here in Spain. Read on for an example of this problem in practice.
Is Your Construction Team Creating a Compliance Risk?
Real Example: Defects Found in a 5€ Million Spanish Villa. Why Imported Expertise Failed on a Premium Spanish Build.
As we are specialists in luxury villa development in Spain, we were recently requested to inspect a newly built €5 million villa that was marketed as being of superior quality, because much of the workforce came from outside Spain. Unfortunately, the reality did not match the promise and many of the problems were actually caused by these international workers.
While skilled workers can come from anywhere, construction methods, materials, regulations, and building standards vary significantly from country to country. In Spain, local construction systems require specific installation techniques and compliance with Spanish building regulations. When teams are unfamiliar with these requirements, mistakes, delays, and costly rework often follow.
In this case, we identified several issues, including:
- Interior-grade tiles used on external entrance steps instead of non-slip surfaces.
- Missing rainwater drainage at the top and bottom of stairways.
- No visible drainage system around the pool terrace.
- Lack of water taps for irrigation and terrace cleaning.
- Poor tile alignment, resulting in noticeable gaps and uneven finishes.
- Oversized front door without draft protection or a spyhole.
- Large-format floor tiles that were not centrally aligned or evenly distributed.
- Hollow-sounding wall panels, suggesting poor installation.
- Stair balustrades below recommended safety heights and unsafe terrace step-ups
- Raised terrace flooring with no accessible maintenance points for drainage systems.
These were only some of the deficiencies observed. In addition to issues such as these, importing materials and staff from abroad regularly causes problems with managing delivery schedules, delays, varying costs due to exchange rates and language and cultural barriers, which can make working on site difficult for all.

What could this mean for the owners? How Construction Defects Can Affect Your First Occupation Licence
These are far from simple or cosmetic snagging items, which are to be expected in a final inspection. Several of these are major issues which not only raise serious safety concerns, but could also jeopardize the project being granted its First Occupation Licence (LPO) and make it uninsurable.
The same safety code states that outdoor public or high-traffic/entrance steps must use Class 3 non-slip tiles, therefore the use of interior grade tiles would cause the property to fail the basic safety inspections that would be required to get your LPO. The slip and fall risk can also cause insurance issues, if a guest, staff member or future buyer slips on the tiles, or falls due to the glass balustrade. An insurer would have a legal right to deny any claim due to lack of compliance, leaving the property owner at risk of paying out compensation.
Last, but not least, if a terrace has raised flooring (suelo técnico) but no accessible hatches to clean or inspect the drains underneath, it fails the habitability and maintenance guidelines required for the building’s permanent documentation (El Libro del Edificio).
Insurance Risks Associated with Non-Compliant Construction
The lack of drainage will also likely cause a formal warning from the independent technical control agency (OCT) as they are red flags for causing water damage. This official warning could cause the insurance company refuse to issue the Decenal policy. Without it, you cannot legally sell the house or get a mortgage. This can also impact any house insurance policy. If the terrace or pool area floods and damages the villa’s foundations or lower levels because there were no drainage points or irrigation taps to manage runoff, the insurer will likely attribute the damage to a “design and construction defect” rather than a sudden, accidental event. Construction defects are universally excluded from standard home insurance coverage.
As you can see, these aren’t details which can be fixed at a later date, these are significant issues and must be solved before the owner can move in.
Why Local Project Management Is Essential for Luxury Developments in Spain.
The lesson from this real life example is simple: construction practices that work well in one country may not be suitable in another. Local building methods exist for good reasons, including climate, maintenance requirements, regulations, and long-established best practices.
Successful projects require more than skilled labour. They need experienced project management, strong technical oversight, and a thorough understanding of local standards. A knowledgeable and local Project Manager in Spain helps ensure quality, compliance, efficiency, and ultimately delivers the project on time and within budget.

Frequently Asked Questions (FAQ)
What is a First Occupation Licence (LPO) in Spain and why is it denied?
A First Occupation Licence (Licencia de Primera Ocupación or LPO) is an essential certificate issued by the local Town Hall confirming a newly built property complies with all health, safety, and habitability laws. An LPO is typically denied if the building violates Spain’s national building code, the CTE (Código Técnico de la Edificación), due to structural defects, inadequate drainage, or safety hazards like illegal balustrade heights. Without an LPO, you cannot legally move into the property, rent it out, or connect it to main utility supplies.
What are the legal height requirements for glass balustrades in Spain?
Under Document DB-SUA (Safety in Use and Accessibility) of the Spanish building code, balustrades must be at least 110 cm high if the potential drop is greater than 6 meters. For drops lower than 6 meters, the minimum legal height is 100 cm. Any step-ups or raised features near the glass that effectively reduce this height will cause the property to fail inspection.
Can using international builders in Spain invalidate my home insurance?
Yes. If your property is built with construction defects or code violations—such as using slippery interior-grade tiles on outdoor entrance steps—insurance companies have the legal right to deny claims for slips, falls, or structural damage. Furthermore, critical drainage omissions can cause the Technical Control Agency (OCT) to issue an official warning, prompting insurers to deny the mandatory 10-year structural insurance policy (Seguro Decenal), which legally blocks future property sales and mortgages.
What tile slip rating is required for outdoor steps in Spain?
Spain’s building regulations state that outdoor public, high-traffic, or main entrance steps must use Class 3 non-slip tiles. Installing interior-grade tiles on external stairways creates a severe slip-and-fall hazard, violates basic safety codes, and will result in a failed local council inspection.
Why do international construction teams struggle with Spanish builds?
While international workforces are highly skilled, they often import building practices, material tolerances, and design standards that do not comply with Spain’s climate or national building code (CTE). Common issues include failing to install mandatory local drainage systems, ignoring required maintenance access points for raised terrace flooring (suelo técnico), and neglecting the legal safety requirements necessary to compile the mandatory building logbook (El Libro del Edificio).
