The Baix Empordà property market — the heart of the Costa Brava — has a large stock of older buildings: village houses, traditional stone farmhouses (masias), coastal homes from the 1960s and 70s, and properties in historic town centres. Many come to market at lower prices precisely because they need work.
For international buyers, this creates a genuine 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. For many buyers, renovation is part of the plan from the beginning — not an afterthought.
The challenge is not the renovation itself. It is managing an unfamiliar process, with local professionals working in a different language, from a different country, often under time pressure. Our own renovation project in Calella de Palafrugell taught us more about that process than any article could. Not because it went fundamentally wrong, but because reality kept moving differently from the plan.
The combination of lower purchase price, strong renovation potential and the possibility of creating something personal in a characterful setting is compelling — particularly in inland villages and older coastal towns where turnkey properties are rare and expensive.
What buyers are typically trying to achieve:
Understanding what a renovation realistically costs, how long it takes and what it demands in terms of management is the most important step a buyer with renovation plans can take — ideally before the purchase contract is signed.
Carries out the physical work. The quality, reliability and communication style of the contractor determine more about the outcome than any other single factor.
Required for projects involving structural changes, extensions or facade modifications. Prepares technical drawings and applies for major permits. Does not typically oversee day-to-day site management.
Oversees the construction process and certifies that work meets specifications. Required on most projects of any significant scope.
Electricians, plumbers, tilers, carpenters, painters. Often subcontracted through the main contractor.
For international owners who are not on site day-to-day, the challenge is not finding good tradespeople — it is making sure they all work towards the same outcome, on the same timeline and within the agreed budget. That coordination rarely happens by itself.
The most underestimated part of a renovation project on the Costa Brava is the permit process. Not because of cost — permit fees are usually manageable — but because of the impact on overall scheduling. Starting late on the permit means waiting later in the project.
For non-structural work: painting, new flooring, replacing fixtures, minor bathroom or kitchen updates without layout changes. The procedure is straightforward — an application to the ayuntamiento, a brief description of works, a licensed contractor to carry them out. Approval typically takes a few weeks.
What surprises buyers: even for projects that are modest in cost, the ayuntamiento can classify them as requiring a licencia mayor. The determining factor is whether the layout or facade is affected — not the budget.
Required for structural changes, extensions, facade modifications and changes to the building's official layout. The application requires technically drawn plans from a registered architect — and depending on the project, a structural report from the aparejador as well.
Legally, the municipality has two months to respond once the file is complete. Official processing time: 3 to 6 months. In practice it can run longer, depending on the municipality's workload and the completeness of the submitted file.
Our own licencia menor in Calella de Palafrugell took 14 weeks — against the Ajuntament de Palafrugell's own estimate of 8. The file was complete at submission. The municipality had a processing backlog and took five weeks to issue its first response. A second iteration followed over a detail in the works description. Two small causes, six weeks extra.
Many properties in historic town centres — particularly in Begur, Pals and Palafrugell — fall under heritage status or urban planning protection rules. These restrict what can be changed on the facade, which materials are permitted, and sometimes even roof pitch and window configuration. The restrictions are set out in each municipality's POUM (Plan d'Ordenació Urbanística Municipal) and are publicly accessible.
Verify a property's heritage status before purchasing. Discovering restrictions after the fact is expensive.

Submitting a permit application is step one. But the Catalan permit process is iterative — the municipality regularly returns applications with a list of observations (requerimientos), the architect addresses them, and the file is resubmitted. Sometimes several times. Anyone unaware of this plans around a timeline the reality doesn't support.
The file is assembled by the architect, typically with input from the aparejador. What it contains as standard: a description of works, technical drawings, a certified commission letter, and depending on the project, a structural report or energy performance assessment.
Submission is digital for most municipalities in Catalonia, but the process runs through the ayuntamiento of the specific municipality. The acknowledgement of receipt marks the start of the official processing period.
We submitted three times in Palafrugell before the file was finally approved. First time: a document in the wrong format. Second time: a technical drawing that didn't match the works description. Third time: a stamp missing from the Collegi d'Arquitectes. Each cost weeks. None was significant. All were preventable.
The tip we now give as standard: have the architect review the complete file before submission — not after.
Few ayuntamientos communicate proactively on progress. If the processing period passes without a response, it is on you — or someone acting on your behalf — to follow up. In some municipalities, direct contact with the official handling the file is the only reliable way to find out where things stand.
Managing that from abroad means navigating language barriers, time zones and the reality that a municipal official is not going to return a call from an unknown foreign number.
The ayuntamiento process in Spain: what actually happens →
The cédula de habitabilidad is the official habitability certificate for a property in Catalonia. It confirms that the property meets minimum standards for occupation: minimum floor area, ventilation, sanitation, natural light. Without a valid cédula, you cannot apply for a water connection in Catalonia — and in some cases, an energy contract either.
For most property purchases in Catalonia, a valid cédula is a condition of notarial transfer. Validity periods are 15 years for properties built or substantially renovated after 2004, and 10 years for older buildings. After a substantial renovation, the cédula must be renewed.
Check whether the cédula is valid and when it expires before purchasing. For a property that needs renovation, the odds that the cédula has lapsed — or was never issued — are significant.
After a full or substantial renovation, the architect applies for the cédula with the Agencia de l'Habitatge de Catalunya, following issuance of the certificat final d'obra.
Our own application in Calella de Palafrugell ran entirely through the architect. After the certificat final d'obra was issued, he filed with the Agencia de l'Habitatge. The process took around six weeks — longer than planned, but not because the procedure was complex. The certificat final d'obra itself was late.
An architect who delivers the certificat final d'obra late blocks the cédula application — and with it, the legal occupation of the property. This is a common bottleneck on renovation projects that run over schedule. Plan the cédula as the project's closing step, not as a formality that takes care of itself.

The contractor determines more about the outcome of a renovation than any other single factor. Yet the selection process is more often driven by chance, an estate agent's recommendation or the lowest quote than by deliberate evaluation.
Demand for quality contractors in Baix Empordà is high. Contractors with a strong reputation have full order books. The gap between quote and start date can run to 3 to 6 months on larger projects.
This has direct implications for scheduling: anyone who expects to start work the day a permit comes through has underestimated how early a contractor needs to be engaged.
What we try to establish in an initial conversation: does the contractor ask immediately about the permit situation? One who doesn't isn't thinking ahead.
On projects above 50,000 euros, we collect at least three quotes as standard. When comparing, look beyond the total figure — are materials specified, are the finishes described, are delivery timelines concrete? Detailed quotes are not always the cheapest, but they are the most honest basis for comparison.

The figures below are indicative. Final costs depend on the property's technical condition, accessibility, material choices, permit requirements and the assessments of the architect and contractor.
| Scope | Typical cost per m² |
|---|---|
| Light cosmetic (paint, floors, fixtures) | 300 to 600 euros |
| Full interior (kitchen, bathrooms, floors, electrical, plumbing) | 800 to 1,500 euros |
| Full structural (structural work, new roof, full systems) | 1,500 to 2,500+ euros |
Use the renovation cost indicator for Baix Empordà to size a budget before you have quotes — it gives a realistic range per m² across three renovation levels.

We work with 15 to 20% contingency on top of quoted amounts as standard. Hidden defects — damp, asbestos, outdated wiring — price increases and mid-project scope changes are common on the Costa Brava, not exceptional.
Initial contractor quotes tend to run 15 to 30% below final project cost. That is not necessarily a sign of bad faith: some discoveries simply aren't visible until the walls come open.
| Indicative total cost, full interior renovation, 120 m² | Amount (€) |
|---|---|
| Interior construction | 120,000 |
| Structural works (damp, roof) | 18,000 |
| Architect and aparejador | 8,000 |
| Permits and administration | 4,500 |
| Contingency (15%) | 22,575 |
| Total | 173,075 |
Not every renovation has to happen in one go. Phasing — beginning with structural work and systems, finishing interiors later — can make sense when the budget is constrained or when you want to see how the project develops before committing to final choices on finishes and fittings.
The permit situation matters here: some combinations of work require that everything falls under a single licencia mayor. Have the architect or aparejador assess whether phasing extends or shortens the overall project timeline before locking it in.
| Scope | Typical duration |
|---|---|
| Light cosmetic renovation | 1 to 3 months |
| Full interior renovation | 3 to 6 months |
| Full structural renovation | 6 to 18 months |
| Projects requiring major permits | Add 3 to 6 months for approval |
The most common factors that extend timelines: permit approval, contractor availability, hidden defects, communication breakdowns and material lead times.
Small decisions that would take five minutes in person become delays of several days by email. Work on site does not wait automatically while you respond.
You cannot inspect work in progress. Work that does not meet specification is significantly cheaper to correct before finishes go on than after.
Most local contractors communicate in Spanish or Catalan. Important information — a structural issue, a supplier delay, a scope change — is sometimes not passed on at all. Not through bad intent, but because communicating with a foreign owner in their language takes effort nobody makes automatically.
Additional cost requests tend to be presented as unavoidable facts. Without someone on site to assess claims, budgets move quietly in one direction.
A pre-purchase assessment by a local professional can prevent significant overcommitment. The assessment costs less than the surprise it prevents.
Initial contractor quotes are almost always below the final project cost. We work with at least 15 to 20% contingency on top of any quote as standard.
Compare quotes carefully and understand what each one includes. Very low quotes often indicate that corners are being cut, or that the difference will be recovered through change orders later.
Working without the correct permits can result in fines, mandatory restoration and serious complications at the point of sale.
In our experience, a contractor who requires more than 20 to 30% upfront is a risk signal. Structure payments around milestones and hold a retention until final sign-off.

An architect is required for structural changes, extensions, facade modifications or changes to the building's official use. For interior-only renovations, an architect is not always legally required — but a technical architect (aparejador) is usually involved regardless on projects of any scope.
Get a realistic renovation cost estimate, understand the permit requirements, check for heritage status that restricts modifications, and verify whether existing works were done with the correct permits. Also check whether the cédula de habitabilidad is valid.
As early as possible. Quality contractors on the Costa Brava carry full order books. In practice, we see the gap between quote and start date run to 3 to 6 months on larger projects. Begin the selection process once you have clarity on the scope — not once the permit arrives.
Yes, but it requires active oversight. Work without someone on the ground quickly leads to quality issues, unnoticed scope changes and additional costs that only surface after the fact. An independent coordinator on site is not a luxury on any project of significant scope.
The architect designs, draws and applies for permits. The aparejador (technical architect) oversees construction and certifies that work meets the technical specifications. On projects requiring a licencia mayor, both are typically involved. On smaller projects, the architect may not be required — the aparejador rarely isn't.
