Renovation in Badalona
Ten kilometres up the coast from the centre, on the metro, with a beach of its own and a price per square metre that still surprises people arriving from northern Europe. Sound structures, exhausted services.

Short answer
What a renovation costs in Badalona
A full renovation in Badalona runs from €780 to €1,600 per m², so a 75 m² flat comes out between €58,500 and €120,000 over 10–14 weeks on site, fixed in writing 48 hours after the technical visit. The figure is this predictable because the 1960s and 1970s blocks that dominate here have sound concrete frames — you are pricing services and finishes, not structural risk. What a foreign buyer should price separately is the building itself: the ITE inspection and any derrama already voted.
| What you are buying | Typical size | Indicative cost | Where the money goes |
|---|---|---|---|
| Flat, 1960–1985 block | 65–85 m² | €50,700–€136,000 | Electrics, plumbing, external joinery |
| Older low-rise, Dalt de la Vila | 70–100 m² | Priced after inspection openings | Timber floor structure, damp |
| Recent development, Gorg | 80–110 m² | €62,400–€121,000 | Layout and finishes only |
| Internal insulation to façade | Per square metre | €55/m² | The best return in this stock |
| Bathroom only | 4–6 m² | from €3,200 | 10–18 working days |
Three things that are not in the listing and not in our quote
- The ITE: the compulsory technical inspection of buildings over 45 years old, commissioned by the residents association — if it has not been passed, some licence applications stall
- A derrama: an extraordinary levy voted by the comunidad de propietarios for lift, roof or façade, which attaches to the flat and becomes yours on the day you sign
- The cédula d’habitabilitat, the certificate of occupancy you need to let the property legally and to connect the utilities
Housing stock
What you actually find in Badalona
Badalona grew quickly between the 1960s and the 1980s to house an industrial workforce. That single fact explains most of what a buyer sees today: blocks from that period with perfectly sound structure and services that have reached the end of their working life.
What comes up most often
- Blocks of 1960 to 1985 in Llefià, La Salut and Sant Roc: modest floor areas, no insulation at all
- Older low-rise property in Centre and Dalt de la Vila, frequently with timber floor structures
- Recent development in Gorg and Montigalà: little to repair, a great deal to personalise
- Detached houses in Canyadó and Bufalà, where roof and envelope enter the budget
The work with the best return
In a 1970s block the biggest gain in comfort per euro spent comes from external joinery with thermal breaks combined with internal insulation to the façade. You notice it the first winter and it shows on the bill. For an owner who intends to let the property, it is also the cheapest way to move the energy rating.
Paperwork
Licences and the ITE at Badalona town hall
Badalona has its own municipal ordinance and its own timescales. What is true in Barcelona is not automatically true ten kilometres up the coast, and assuming otherwise costs weeks.
What each type of work needs
- Interior work not touching structure: comunicación previa, a notification to the ayuntamiento
- A change of layout affecting structure: licencia de obra menor with a technical project
- Extension, roof or façade: licencia de obra mayor
- Any work in a building over 45 years old: the ITE may need to be current
What the ITE is
The Inspecció Tècnica de l’Edifici is a compulsory technical inspection for buildings over 45 years old, commissioned by the residents association rather than by an individual owner. If the building has not passed it, certain licence applications stall. We check the status before filing anything, because it is not something a foreign owner would normally think to ask about.
What buying here actually involves
Badalona rewards buyers who look at the building rather than only at the flat. A block from 1972 can have a sound frame, a lift that was retrofitted into the stairwell, no insulation whatsoever and a rising main that has never been touched, and none of that appears in the listing. Before committing, it is worth establishing three things: whether the ITE is current, whether the residents association has any major works already voted and levied, and whether the flat has an individual gas connection or none at all. Each of those changes the renovation budget by a meaningful amount, and each is far cheaper to discover before exchange than afterwards.
Frequently asked
Renovations in Badalona: common questions
Between €780 and €1,600 per m² for a full renovation. For a 75 m² flat that is €58,500 to €120,000 depending on finishes, fixed in writing 48 hours after the technical visit.
For interior work that does not touch structure, a comunicación previa to the ayuntamiento. If structure or façade is modified, a licencia de obra menor or mayor with a technical project. The filing is handled for you.
It is the compulsory technical inspection of buildings over 45 years old. If your building has not passed it, some licence applications are delayed. It is the residents association that commissions it, not you, so we verify the status before filing.
It is the best cost-to-benefit intervention in that building type. New external joinery plus internal insulation to the façade eliminates the draughts and produces a clear, measurable reduction in heating costs.
Yes. Filing the comunicación previa or the licence application, commissioning the technical project where one is required, and following the file through the ayuntamiento are all part of the job. You do not have to be in the country for any of it.

What we learn on site
Real housing problems in Barcelona, explained by the people who fix them.
Doors: lacquer or replace
Nearly every flat bought in Barcelona comes with dark varnished doors from another era. Lacquering them white is the most visible improvement per euro that exists — on the right doors. On the wrong ones it is money thrown away.
Common mistakes
Very few renovation mistakes are dramatic. Most are small decisions taken quickly, in the wrong order, that you then live with for fifteen years.
Open or closed kitchen
The decision is presented as a matter of taste. It is mostly a matter of how you cook, how the flat is built, and what you will do with the property in ten years.
