Renovating Property in Costa Brava: A Complete Guide
A practical guide to renovating property in Costa Brava as an international owner — what to expect, what it costs, how permits work and how to manage a project from abroad. Written specifically for non-resident buyers purchasing and renovating property in the Baix Empordà and Costa Brava region.
THE OPPORTUNITY
Waarom kopers renoveren
aan de Costa Brava
The Costa Brava housing market has a large stock of older properties — village houses, traditional stone farmhouses (masies), coastal homes from the 1960s and 70s, and properties in historic town centres. Many of these come to market at lower prices precisely because they need work.
For international buyers, this creates a clear opportunity: purchase a characterful property at a competitive price, invest in renovation and end up with a home that combines local character with modern comfort — often at a total cost below what a turnkey property would have cost.
Common reasons buyers renovate:
- Modernising outdated interiors while preserving architectural character
- Improving energy efficiency for year-round comfort
- Adapting the layout for family use or rental purposes
- Restoring traditional architectural features such as stone walls, vaulted ceilings or original tiles
- Adding outdoor spaces, pools or terraces
- Bringing a property up to modern building standards
For many buyers, renovation is part of the property strategy from the beginning — not an afterthought. The key is understanding what you are committing to before you buy.
THE PROFESSIONALS
Who is involved in a renovation project in Spain?
Renovating property in Spain involves multiple independent professionals, each responsible for their own area. Understanding who does what — and how they interact — is one of the most important things to get right before a project starts.
Main professionals involved in renovation projects:
- Contractor (empresa constructora) — carries out the physical work. May specialise in structural work, general building, or specific trades.
- Architect (arquitecto) — required for projects involving structural changes, extensions or facade modifications. Prepares technical drawings and applies for major permits.
- Technical architect (aparejador / arquitecto técnico) — oversees the construction process and certifies that work meets specifications. Required on many projects.
- Interior designer — coordinates finishes, materials and aesthetics. Optional but valuable for full renovation projects.
- Specialist tradespeople — electricians, plumbers, tilers, carpenters, painters. Often subcontracted through the main contractor.
- Suppliers — materials, fixtures, fittings. Lead times can affect project timelines significantly.
Each of these professionals works within their own scope. For international owners who are not on site day-to-day, the challenge is not finding good professionals — it is making sure they all work together towards the same outcome, on the same timeline and within the agreed budget.

PERMITS
Zijn vergunningen nodig voor renovaties in Spanje?
Yes — in most cases. Whether a permit is required, and what type, depends on the scope of the work and the municipality where the property is located. Understanding permit requirements before buying a property with renovation plans is essential.
Types of permit in Spain:
- Minor works permit (licencia de obras menores) — for cosmetic and non-structural work: painting, tiling, replacing fixtures, minor bathroom or kitchen updates. Faster to obtain, lower cost.
- Major works permit (licencia de obras mayores) — required for structural changes, extensions, facade modifications, changes to the building’s layout or use. Requires architect-prepared technical drawings and typically takes 1–4 months to obtain.
- End-of-works certificate (certificado de fin de obra) — required after major works are completed. Certifies that the work matches the approved plans.
Special considerations in Costa Brava:
- Many properties in the region have special architectural or heritage status, which restricts what modifications can be made to facades and exteriors.
- Some municipalities in Baix Empordà have specific local regulations regarding property extensions and roof modifications.
- Properties in protected natural areas (e.g. near the Parc Natural del Cap de Creus or protected coastline) face additional restrictions.
Starting work without the correct permit can result in fines, orders to restore the property to its original state and complications when selling. Always verify permit requirements before starting any work — even works that seem minor.

RENOVATION COSTS
What does renovation in Costa Brava actually cost?
Renovation costs in Costa Brava vary significantly depending on the property, the scope of work and the quality level of materials and finishes. There is no reliable fixed price per square metre — costs depend entirely on the project.
Rough cost ranges (Costa Brava, 2024–2025):
- Light cosmetic renovation (paint, floors, fixtures): €300–€600/m²
- Full interior renovation (kitchen, bathrooms, floors, electrical, plumbing): €800–€1,500/m²
- Full structural renovation (structural work, new roof, full systems): €1,500–€2,500+/m²
Additional costs to factor in:
- Architect and technical architect fees: 5–10% of construction cost
- Permit costs: vary by municipality and project size
- Project management or coordination fees
- Contingency: always budget 15–20% extra — especially in older properties
Important: In older properties — traditional stone houses and pre-1980s coastal buildings — hidden issues are common. Structural problems, outdated electrical systems and damp are frequently discovered once work begins. A contingency budget is not optional — it is essential.
Practical example: Full interior renovation of a 120m² village house at €1,000/m²:
- Construction cost: €120,000
- Architect fees (approx.): €8,000
- Permit costs (approx.): €2,000
- Contingency 15%: €18,000
- Total budget: approx. €148,000
TIMELINES
How long does renovation take in Costa Brava?
Renovation timelines depend heavily on scope, contractor availability and the permit process.
Realistic timeframes by project type:
- Light cosmetic renovation: 1–3 months
- Full interior renovation: 3–6 months
- Full structural renovation: 6–18 months
- Projects requiring major permits: add 1–4 months for permit approval on top
What causes delays?
- Permit approval timelines — especially for major works
- Contractor availability — skilled tradespeople in the Costa Brava are in high demand
- Material delivery delays
- Hidden problems discovered during work
- Changes in project scope — common when owners see the property stripped back
- Communication breakdowns between the different professionals involved
For international owners who are not on site full-time, delays are harder to detect and manage. A project that is running behind is rarely communicated proactively by contractors — it needs to be actively monitored.

MANAGING FROM ABROAD
Why renovation from abroad is harder — and how to manage it.
Managing a renovation project remotely is one of the biggest practical challenges international owners face. It is not impossible — but it requires a clear structure, reliable local contacts and a communication system that keeps you genuinely informed about what is happening on the ground.
The specific challenges of remote renovation management:
- Decision-making delays — when questions arise on site that need owner input, not being locally available creates delays. Small decisions become bottlenecks.
- Quality oversight — you cannot inspect work in progress. By the time you visit, problems may already be covered up or far advanced.
- Communication gaps — most local contractors in the Costa Brava communicate primarily in Spanish or Catalan. Nuance is lost in translation, and important information is sometimes not passed on at all.
- Budget creep — additional costs tend to be presented as unavoidable facts rather than decisions. Without someone on site reviewing and challenging claims, budgets move quietly.
- Contractor coordination — when multiple tradespeople are working on the same project, coordination between them is needed. Without oversight, they work around each other rather than together.
What effective remote management looks like:
- Regular structured progress updates — with photos, not just verbal reports
- Clear written documentation of all decisions, changes and additional costs
- An independent person on the ground who represents your interests — not the contractor’s
- A payment structure that aligns with progress milestones, not just invoices submitted
- Planned site visits at key stages: before work starts, after structural work, after first fix, before finishes

COMMON MISTAKES
What international buyers often get wrong when renovating in Spain.
Renovation projects in Spain are not inherently difficult — but there are specific mistakes that international buyers make repeatedly. Most of them are avoidable with the right preparation.
Not getting a renovation assessment before buying
Many buyers fall in love with a property and commit to purchasing it before they have any realistic idea of what the renovation will cost or involve. A pre-purchase renovation assessment by a local professional — even an informal one — can prevent very expensive surprises. → Read more about what to check before buying property in Spain
Underestimating costs and timelines
Initial contractor quotes are almost always lower than the final project cost. Scope changes, hidden issues and material price movements all push costs up. Budget at least 15–20% contingency on top of any quote you receive.
Choosing the lowest quote
The cheapest contractor is rarely the best value. In the Costa Brava market, very low quotes often indicate that the contractor is cutting corners, underestimating the scope, or planning to recoup the difference through change orders later. Compare quotes carefully — and understand what each one includes and excludes.
Starting work before permits are in place
Working without the correct permits can result in fines, mandatory restoration of the original state and serious complications when selling. The fact that “everyone does it” does not protect you if the municipality inspects the property.
No written documentation
Verbal agreements, changes made informally, and undocumented decisions create disputes. Everything should be in writing: the original contract, any changes to scope, any additional costs agreed. This is especially important when you are managing the project from abroad.
Paying too much upfront
A contractor who requires more than 20–30% upfront before work begins is a risk. Structure payments around milestones: a deposit to start, payments at key stages (foundations complete, first fix complete, finishes complete), and a retention held until final sign-off.

FREQUENTLY ASKED QUESTIONS
Common questions about renovating
property in Costa Brava.
Do I need a permit to renovate property in Spain?
In most cases, yes. Minor cosmetic works — painting, tiling, replacing fixtures — typically require a minor works permit. Structural changes, extensions, facade modifications and changes to the building’s layout require a major works permit, which needs architect-prepared drawings and takes longer to obtain. Always verify permit requirements with the local municipality before starting any work.
How much does renovation cost in Costa Brava?
Costs vary widely by scope and quality level. As a rough guide: light cosmetic renovation €300–€600/m², full interior renovation €800–€1,500/m², full structural renovation €1,500–€2,500+/m². Always add 15–20% contingency, especially in older properties where hidden issues are common.
How long does a renovation project take in Costa Brava?
Light cosmetic renovation: 1–3 months. Full interior renovation: 3–6 months. Full structural renovation: 6–18 months. Projects requiring major permits add permit approval time on top — typically 1–4 months. Contractor availability and material delivery times also affect timelines significantly.
Can I manage a renovation from abroad?
Yes — but it requires clear structure, reliable local contacts and a good communication system. The key challenges are decision-making delays, quality oversight, communication gaps and budget creep. Having an independent coordinator on the ground who represents your interests — not the contractor’s — makes a significant difference.
Do I need an architect for a renovation in Spain?
An architect is required for projects involving structural changes, extensions, facade modifications or changes to the building’s official use. For interior-only renovations without structural changes, an architect is not always legally required — but a technical architect (aparejador) is often recommended to oversee the work.
What should I check before buying a property that needs renovation?
Before committing to a property with renovation plans: get a realistic renovation estimate from a local professional, understand the permit requirements for the work you have in mind, check whether the property has any heritage or architectural restrictions, and factor the full renovation budget — including contingency — into your total investment calculation. → Read the full guide on buying property in Spain
