Renovation in Granollers and Mollet del Vallès
Half an hour north of Barcelona you get the floor area the city stopped offering. What comes with it is a 1970s services installation and two town halls that do not follow Barcelona rules.

Short answer
What a renovation costs in Granollers and Mollet
A full renovation in Granollers or Mollet runs from €780 to €1,600 per m², so a typical 85 m² flat of the 1970s comes out between €66,300 and €136,000. On site that is 11–15 weeks, with the municipal paperwork running in parallel rather than before. The figure is fixed in writing within 48 hours of the technical visit.
The range is this predictable because of the building period: blocks put up between 1965 and 1985 have a concrete frame that is almost always sound, so you are pricing services and finishes, not structural risk.
| What you are buying | Typical size | Indicative cost | Where the money goes |
|---|---|---|---|
| Flat, 1960s–80s block | 70–100 m² | €54,600–€160,000 | Electrics, plumbing, external joinery |
| Town house between party walls | 110–160 m² | Priced after inspection openings | Roof, damp, timber joist bearings |
| Development from the 2000s | 80–110 m² | €62,400–€121,000 | Layout and finishes, little repair |
| One bathroom only | 4–6 m² | from €3,200 | 10–18 working days |
| One kitchen only | 8–12 m² | from €4,500 | 12–25 working days |
What moves the number
- Whether the supply needs a new boletí before reconnection
- How far a second bathroom sits from the existing soil stack
- A top floor, where roof and insulation join the scope
- A narrow lift: split deliveries, small-format materials
The property stock
What you are actually looking at here
Granollers and Mollet grew on industry between the sixties and the eighties, which left two very different things to buy.
Flats of the 1970s and 1980s
Three or four small bedrooms, a long corridor and a living room that never worked. The frame is fine; the wiring, pipework and windows are finished. All three mean opening walls, so doing them together costs far less than in stages — otherwise you pay for the same wall twice.
Town houses in the old centres
Load-bearing masonry, timber or ceramic joists, usually a rear patio. Before a price exists we open inspection holes at the joist bearings and check for rising damp, because that is where a quote either holds or collapses. The patio, resolved properly, becomes the most used room in the house; roofing it over needs a licence.
For non-resident owners
Buying here from abroad, and the three words you need
Most foreign buyers here want floor area and the R2 and R3 lines into Barcelona. The work usually happens while you are in another country — fine, provided the parts needing a signature are known in advance.
Comunicació prèvia or a licence
Interior work that leaves the structure and façade alone is a comunicació prèvia: you notify the town hall and work can begin. Touch the structure or a communal element and it becomes a licence with a technical project, which adds weeks. Granollers, Mollet and Parets each have their own ordinances. We file in your name.
Cédula d’habitabilitat
The certificate of occupancy issued by the Generalitat. You need a valid one to let the flat legally and to get utilities connected, existing homes are certified for fifteen years, and a renovation that moves a bathroom normally means a new one is issued afterwards.
Comunidad and derrama
The comunidad de propietarios is the owners association that runs the block and votes its budget. It wants a liability policy, permitted noise hours and lift permission, which we file in advance. A derrama is an extraordinary levy it votes for building-wide work — lift, roof, façade — charged to owners on top of the monthly fee. Not in our quote, but yours to pay. Read the last two sets of meeting minutes before you buy.
How the job runs without you
- Fixed written quote after the technical visit, not a range that drifts
- Photographs at each stage, decisions sent before they are needed
- Material choices grouped into batches, not one at a time
- Deliveries, waste and the skip permit are ours, not yours
Frequently asked
Renovations in Granollers i Mollet: common questions
An 85 m² flat comes out between €66,300 and €136,000 depending on the level of finish. In 1970s blocks the number is unusually predictable because the concrete frame is normally sound and there is no structural unknown to price.
Often, and in a family flat it changes daily life more than any finish. It depends on the floor area and on the distance to the existing soil stack, since the waste run needs fall. We confirm it at the technical visit rather than assuming it.
No. Granollers, Mollet, Parets and the surrounding municipalities are standard coverage, 25 to 30 km out with direct access by AP-7 and C-17. Same price per square metre, same weekly reporting.
Electrics and plumbing, then external joinery. None of it shows, all of it decides safety, comfort and your energy bill for decades. Each means opening walls, so one pass is cheaper than stages.
Yes. We establish whether the work is a comunicació prèvia or a licence with a technical project, file it in your name, and deal with the residents association directly. Granollers and Mollet each have their own procedure and neither follows Barcelona.

What we learn on site
Real housing problems in Barcelona, explained by the people who fix them.
VAT on renovations
Two invoices for the same kitchen can differ by eleven percentage points of tax without a single thing about the work having changed. What decides the rate is the building, the buyer and the proportion of materials — never the contractor.
Children and pets
Most of a renovation is compatible with family life. A handful of days are not, and they are known weeks in advance — which is exactly what makes them manageable.
Permits
Not every renovation needs a licence. Barcelona has an immediate filing for minor works, and picking the right one is the difference between starting next week and starting in two months.
